Description

押して切る粘着テープPress and cut adhesive tape
 本発明は、包装、紙などの貼り付けに用いる帯状粘着テープ及び、容器と蓋の固定、食品パックの束の結束など一時的な固定に用いる帯状粘着テープであって、短手方向の中央付近に、粘着テープの長手方向に沿って複数の切れ込みまたは、切れ込みに替えてミシン目やミシン目の集合が間隔を開けて連続的に形成された、切断容易性を有する「押して切る粘着テープ」に関する。  The present invention relates to a strip-like adhesive tape used for attaching packaging, paper, and the like, and a strip-like adhesive tape used for temporary fixation such as fixing of a container and a lid, binding of a bundle of food packs, and the vicinity of the center in the short direction In addition, a plurality of cuts along the longitudinal direction of the pressure-sensitive adhesive tape, or a perforation or a group of perforations formed continuously at intervals in place of the cuts, which relates to a “push-cut pressure-sensitive adhesive tape” having ease of cutting. .
 従来から、帯状の粘着テープの切断には、ハサミやテープカッター等の切断具を用いるか、指で粘着テープを挟んでねじ切るといったことが行われてきた。
 しかし、子供にとって切断具の使用は困難な場合がある。また、切断具が手元にない場合に、指でねじ切ろうとすると、粘着テープの手切れ性が悪いために切断できない場合や切断できても粘着テープ同士が互いに付着し合う場合があり、所望通りの切断に多くの手間がかかって煩雑であった。 
 また、容器と蓋の固定、食品パックの束の結束や、ダンボール箱の蓋の封印など一時的な固定に粘着テープが用いられてきたが、開封に手間がかかったり、カッターなどの刃物を用いると商品を傷つけたりする恐れがあった。
 このような事態を回避する目的で、粘着テープにミシン目等の切断部を設けて切断を容易とするような技術が開発されており、それに関して既にいくつかの発明が開示されている。 
Conventionally, cutting of a strip-shaped adhesive tape has been performed using a cutting tool such as scissors or a tape cutter, or by screwing the adhesive tape with a finger.
However, it may be difficult for a child to use a cutting tool. In addition, when the cutting tool is not at hand, if you try to thread it with your finger, the adhesive tape may adhere to each other if it cannot be cut due to poor hand cutting properties of the adhesive tape or even if it can be cut. Cutting took a lot of time and was cumbersome.
Adhesive tape has also been used for temporary fixing, such as fixing containers and lids, bundling bundles of food packs, and sealing lids on cardboard boxes. There was a risk of damaging the product.
In order to avoid such a situation, a technique has been developed in which a cutting part such as a perforation is provided on the adhesive tape to facilitate cutting, and several inventions have already been disclosed in this regard.

 次に、特許文献2には、「易裂性粘着テープ」という名称の発明が開示されている。 
 特許文献2に開示された発明は、非伸長性で、寸法安定性のプラスチックフィルムからなる基材の片面全面に微細な凹部を形成し、フィルムの少なくとも片面に粘着剤層を設けたことを特徴とする。 
 このような構成の発明においては、包装作業時等に加わる引張強度に耐える強度を有するとともに、切断器具を必要とせずに容易に端部から切り裂くことができる程度の端裂抵抗を有する。 
Next, Patent Document 2 discloses an invention named “easy tearable adhesive tape”.
The invention disclosed in Patent Document 2 is characterized in that a fine recess is formed on the entire surface of one side of a non-extensible and dimensionally stable plastic film, and an adhesive layer is provided on at least one side of the film. And
In the invention having such a configuration, it has a strength that can withstand the tensile strength applied during the packaging operation and the like, and has an end tear resistance that can be easily cut from the end portion without requiring a cutting tool.
 特許文献3には、「切れ目を入れた強力粘着テープ」という名称の考案が開示されている。 
 特許文献3に開示された考案は、強力粘着テープの側面から20度以内の角度をもって切り込みが設けられ、この切れ込みは両側面より交互に設けられるという特徴を有する。 
 このような構成の強力粘着テープにおいては、切れ込みを設けたことにより、側面から容易に粘着テープを切断できる。 
Patent Document 3 discloses a device named “strong adhesive tape with a cut”.
The device disclosed in Patent Document 3 is characterized in that cuts are provided at an angle of 20 degrees or less from the side surface of the strong adhesive tape, and the cuts are alternately provided from both side surfaces.
In the strong adhesive tape having such a configuration, the adhesive tape can be easily cut from the side surface by providing the cut.
 特許文献4には、「手切れ性粘着テープ及びその製造装置」という名称で、手切れ性を維持し、引張強度等を向上させた粘着テープ及びその製造装置に関する発明が開示されている。 
 特許文献4に開示された発明は、帯状プラスチックフィルム基材の一面に粘着層を設けて形成した粘着テープにおいて、この長手方向に沿って一定間隔をおいて連続する孔を形成し、各孔は角部を有しない形状で、テープ側縁より1.5mm以上の内側に設けられ、テープの幅方向に手切れ性が容易となるという特徴を有する。 
 このような構成の手切れ性粘着テープにおいては、手切れ性は損なわれず、また各孔における製造及び取扱作業時に応力が集中する箇所がないため、引張強度及び引張伸び率が向上する。 
Patent Document 4 discloses an invention relating to a pressure-sensitive adhesive tape that maintains hand-cut property and has improved tensile strength and the like, and a device for manufacturing the same, under the name “hand-cut adhesive tape and its manufacturing device”.
The invention disclosed in Patent Document 4 is a pressure-sensitive adhesive tape formed by providing a pressure-sensitive adhesive layer on one surface of a belt-shaped plastic film substrate, and forming continuous holes at regular intervals along the longitudinal direction. It is a shape that does not have a corner, and is provided on the inner side of 1.5 mm or more from the side edge of the tape.
In the hand-cut adhesive tape having such a configuration, the hand-cut performance is not impaired, and there is no portion where stress is concentrated in the manufacturing and handling operations in each hole, so that the tensile strength and the tensile elongation are improved.

In the adhesive tape having such a configuration, since the scar as a starting point of cutting is given at an inner position away from the end edge of the tape, there is no decrease in the strength of the end edge of the tape. Alternatively, the disadvantages of unintentional cutting from the end edge due to excessive tension, fluctuating tension, and oblique tension, which have been a problem with the prior art easy-cut adhesive tape having a scar near the end edge, are greatly improved.
 特許文献6には、「ミシン目入り一般包装用粘着テープ」という名称で、テープを貼付後に、容易に手で切り離すことのできる粘着テープに関する考案が開示されている。 
 特許文献6に開示された考案は、一般包装用粘着テープの幅の中央部附近に、テープの長さ方向に沿ってミシン目を入れたことを特徴とする。

 特許文献1に開示された考案においては、ミシン目状のスリットを設けた切り込み部を設けたことにより、切断金具等を使用することなく確実、容易に粘着テープを切断できる。 
 しかし、包装、容器と蓋の固定、食品パックの束の結束、紙などの貼り付けなどに用いられる粘着テープのフィルム基材は薄いので、この方法では引張強度が確保できず切れてしまう。また、手指で切断する場合には、切り込み部を間に入れてその両側の切り込み部でない部分を手指で挟持しテープをねじ切る必要があるので、両手を必要とする。よって、作業中に片手がふさがっている場合には、その作業を中断してテープを切断後に作業を再開しなければならず、容易に粘着テープを切断できるとはいえない場合がある。また、手指が粘着面に触れるので、指紋の跡が粘着テープに残り美観を損ねる場合がある。さらに、切断後に粘着テープが手指に絡みつき粘着テープを貼り付けることが困難な場合がありうる。 
In the device disclosed in Patent Document 1, the adhesive tape can be reliably and easily cut without using a cutting metal fitting or the like by providing a cut portion provided with a perforated slit.
However, since the film base material of the adhesive tape used for packaging, fixing the container and lid, bundling a bundle of food packs, attaching paper or the like is thin, the tensile strength cannot be secured by this method and the film is cut. Further, when cutting with fingers, it is necessary to insert both incisions and sandwich the portions that are not the incisions on both sides with fingers to screw the tape, so both hands are required. Therefore, when one hand is blocked during the work, the work must be interrupted and the work must be resumed after cutting the tape, and it may not be easy to cut the adhesive tape. In addition, since the finger touches the adhesive surface, the trace of the fingerprint may remain on the adhesive tape and impair the appearance. Furthermore, it may be difficult for the adhesive tape to get entangled with fingers after cutting and to stick the adhesive tape.
 次に、特許文献2に開示された発明においては、包装作業時等に加わる引張強度に耐える強度を有するとともに、切断器具を必要とせずに容易に端部から切り裂くことができる程度の端裂抵抗を有する。 
 しかしながら、フィルムの手切れ性向上のため基材フィルムの側端部は凹部の形成密度を大にしている。一方、幅方向中心部領域は引張力に抗するよう側端部よりも粗密度に形成される。したがって、手切れ性はもっぱら基材フィルムの側端部において良好であり、最初に基材フィルムの側端部を引き裂く際に、その方向によっては中心部に切れ込みが及ばず側端部のみが分離する可能性がある。これを防止するためには、特許文献1に開示された考案と同様に切断したい部分を手指で確実に挟持しテープをねじ切る必要があるので、煩雑となる場合がある。よって、作業効率が低下するおそれがある。また、全面に微細な凹部を形成するためテープ表面への印刷に影響を与える可能性がある。 
Next, the invention disclosed in Patent Document 2 has an endurance resistance that can withstand the tensile strength applied during packaging operations and the like and can be easily cut from the end without the need for a cutting tool. Have
However, in order to improve the hand cutting property of the film, the side end portions of the base film have a large formation density of the concave portions. On the other hand, the central region in the width direction is formed with a coarser density than the side end portion against the tensile force. Therefore, the hand cutting property is good mainly at the side edge of the base film, and when the side edge of the base film is first torn, depending on the direction, the center does not cut and only the side edge is separated. there's a possibility that. In order to prevent this, as in the device disclosed in Patent Document 1, it is necessary to securely pinch a portion to be cut with fingers and screw the tape, which may be complicated. Therefore, there is a possibility that work efficiency may be reduced. In addition, since fine concave portions are formed on the entire surface, printing on the tape surface may be affected.
 特許文献3に開示された考案においては、20度以内の角度で切れ込みを設けたことにより、側面から容易に粘着テープを切断できる。 
しかし、側縁部に切れ込みをつけるため、側縁にかかる力により粘着テープは非常に切れやすくなる。このため、粘着テープの巻体からフィルム基材を剥がす時に側縁部に力が加わると裂けてしまい巻体から剥がすことが難しい。 
In the device disclosed in Patent Document 3, the adhesive tape can be easily cut from the side surface by providing the cut at an angle of 20 degrees or less.
However, since the side edge is cut, the adhesive tape is very easily cut by the force applied to the side edge. For this reason, when a film base material is peeled off from the wound body of the adhesive tape, if a force is applied to the side edge portion, it tears and is difficult to peel off from the wound body.
 特許文献4に開示された発明においては、手切れ性は損なわれず、また引張強度及び引張伸び率が向上する。 
 しかし、取扱作業時に応力が集中する箇所がないため、かえってテープの切断方向が一定とはならないことが考えられる。よって、所望通りに切断できず新たに切断器具等が必要となる可能性があり、手切れ性が維持されているとはいえない。さらに、粘着テープの側縁部近くにスリットがあるため、取り扱い中に側縁部が分離して手にまとわりつく可能性があり、作業性が悪い。また、スリットのため粘着テープの外観品質やテープ表面への印刷に影響を与える。
In the invention disclosed in Patent Document 4, hand cutting performance is not impaired, and tensile strength and tensile elongation are improved.
However, since there is no portion where stress is concentrated during the handling operation, it is conceivable that the cutting direction of the tape is not constant. Therefore, it may not be cut as desired, and a new cutting tool or the like may be required, and it cannot be said that the hand cutting property is maintained. Furthermore, since there is a slit near the side edge portion of the adhesive tape, the side edge portion may be separated during handling and cling to the hand, resulting in poor workability. In addition, the slit affects the appearance quality of the adhesive tape and the printing on the tape surface.
 特許文献5に開示された発明においては、本願と同様に粘着テープを上から押して切断する。粘着テープには、短手方向に沿って0.5mm間隔で傷痕を7列千鳥状に付与した例があるように、この切断方法はミシン目を切るように上から押す力で不特定の隣接する傷跡をつないで切断する方法である。この粘着テープは切断した切断端のすぐ近くに多くの傷跡があるため、巻体から粘着テープの切断端を剥がす際に切断端近くの傷跡に力が加わり粘着テープ縦に切れてしまい使用できない可能性が高い。また、一時的固定にこの粘着テープを用いると意図せぬ力により傷痕群に沿って切れる可能性が高い。 In the invention disclosed in Patent Document 5, the adhesive tape is pressed from above and cut as in the present application. As in the case of adhesive tape, in which there are 7 rows of staggered marks at 0.5 mm intervals along the short direction, this cutting method is unspecified by the force of pushing from above to cut perforations. It is a method of cutting by connecting scars to be cut. This adhesive tape has many scars in the immediate vicinity of the cut end, so when peeling the adhesive tape's cut end from the roll, force is applied to the scar near the cut end and the adhesive tape cuts vertically and can not be used. High nature. Moreover, when this adhesive tape is used for temporary fixation, there is a high possibility that the adhesive tape will be cut along the scar group by an unintended force.
 特許文献6に開示された考案においては、包装用粘着テープの短手方向中央部にミシン目が形成されたもので、ミシン目部分から切断して連結された段ボール箱の分離を行うものである。この粘着テープは、ミシン目を利用して切るため、輸送中などに外部からの力により切れやすい可能性がある。さらに、段ボール箱の合わせ目とミシン目を一致させる必要があるため、箱の連結時に注意が必要である。 In the device disclosed in Patent Document 6, a perforation is formed at the center in the short direction of the packaging adhesive tape, and the cardboard boxes connected by cutting from the perforation are separated. . Since this adhesive tape is cut using a perforation, it may be easily cut by an external force during transportation. Furthermore, since it is necessary to match the seam and the perforation of the cardboard box, care must be taken when connecting the boxes.
 上記のように切断器具を用いないで粘着テープを切断する場合の解決すべき主な課題は、簡単な操作で切断可能でありながら引張強度を確保できることである。また、切断時に粘着面に触れないこと及び側縁部のみが切れないこと、切断時や粘着テープを巻体から剥がす時などに粘着テープが意図に反して切れないこと、粘着テープの外観品質維持や、物品の一時的な固定に用いた粘着テープが物品の固定解除時以外に切れにくく、必要時には固定解除しやすいこと等である。 
 本発明は、上記課題の少なくとも一つを解決するために、指先や爪で粘着テープ表面を上方から押すことにより、粘着テープの長手方向の任意の位置で容易に切断可能な押して切る粘着テープを提供することを目的とする。さらには、引張強度と切断容易性を調整可能な押して切る粘着テープを提供することを目的とする。
The main problem to be solved when cutting an adhesive tape without using a cutting tool as described above is that a tensile strength can be secured while being cut by a simple operation. Also, do not touch the adhesive surface when cutting, and only the side edges will not be cut, the adhesive tape will not cut unintentionally when cutting or peeling the adhesive tape from the roll, etc., maintaining the appearance quality of the adhesive tape In addition, the adhesive tape used for temporarily fixing the article is difficult to break except when the article is unfixed, and is easily released when necessary.
In order to solve at least one of the above problems, the present invention provides an adhesive tape that can be easily cut at any position in the longitudinal direction of the adhesive tape by pressing the surface of the adhesive tape from above with a fingertip or a nail. The purpose is to provide. It is another object of the present invention to provide a pressure-sensitive adhesive tape that can be adjusted by adjusting its tensile strength and ease of cutting.
 上記目的を達成するため、請求項1記載の発明は、帯状フィルム基材の少なくとも一面に粘着層を備えた,押して切る粘着テープであって、帯状フィルム基材の長手方向に沿って,複数の貫通する長さが0.3mm以上かつ3mm以内である切れ込みが間隔を空けて連続的に配置され列を形成し、この列は帯状フィルム基材の短手方向の中央に1列設けられ、さらにそれら貫通する切れ込みの長手方向が帯状フィルム基材の長手方向に対し角度α(10度≦|α|≦60度)をもって形成されたことを特徴とする。
 なお、本願において帯状フィルム基材とは、粘着テープの支持体を指し、短手方向の中央とは、略中央あるいは中央付近も含む概念である。
In order to achieve the above object, the invention described in claim 1 is a pressure-sensitive adhesive tape provided with an adhesive layer on at least one surface of a strip-shaped film substrate, and a plurality of strips along the longitudinal direction of the strip-shaped film substrate. The incisions having a length of not less than 0.3 mm and not more than 3 mm are continuously arranged at intervals to form a row, and this row is provided in the center of the strip-shaped film base in the short direction, and further, The longitudinal direction of the notches penetrating them is formed with an angle α (10 degrees ≦ | α | ≦ 60 degrees) with respect to the longitudinal direction of the strip-shaped film substrate.
In addition, in this application, a strip | belt-shaped film base material points out the support body of an adhesive tape, and the center of a transversal direction is a concept also including substantially the center or the center vicinity.
 請求項1記載の押して切る粘着テープを切断するには、押して切る粘着テープの長手方向の任意の部分を手で固定するか、物体に貼りつけ固定し、押して切る粘着テープの短手方向の中央付近を帯状フィルム基材面に対し上から、指の先端部分か爪の部分で押す。これにより押して切る粘着テープの固定された部分と押した部分との間に引っ張る力が生じる。この引っ張る力が、帯状フィルム基材の短手方向中央につけた切れ込み自体を拡張する力となる。また、帯状フィルム基材は幾らかの伸長性があるため、切れ込みは押した部分から離れるほど拡張し難くなることから、
押した部分に最も近い切れ込みが拡張し始める。さらに、粘着テープを長手方向に引っ張る力が作用しているので、切れ込みは押して切る粘着テープの短手方向の両側縁部に向かって拡張する。従って、切断時に押して切る粘着テープが長手方向に裂けることがない。また、切れ込みは押して切る粘着テープの短手方向の中央に形成されているので、特許文献4のように側縁部のみが切れることがない。
 また、本発明の押して切る粘着テープにおいては、切断には一つの切れ込みしか関与しないので、特許文献1におけるミシン目状の切り込み部のように粘着テープの短手方向に沿って隣接する切れ込み同士を近づけてつながりやすくする必要がない。
In order to cut the adhesive tape to be pressed and cut according to claim 1, an arbitrary portion in the longitudinal direction of the adhesive tape to be pressed and cut is fixed by hand or fixed to an object, and the center in the short direction of the adhesive tape to be pressed and cut. Press near the top of the band-shaped film base with the tip of your finger or the nail. As a result, a pulling force is generated between the fixed part and the pressed part of the pressure-sensitive adhesive tape to be pushed and cut. This pulling force becomes a force that expands the cut itself made in the center in the short direction of the belt-like film substrate. In addition, since the band-shaped film substrate has some extensibility, the notch becomes difficult to expand as it moves away from the pressed part,
The notch closest to the pressed part begins to expand. Furthermore, since the force which pulls an adhesive tape to a longitudinal direction is acting, a notch expands toward the both-sides edge part of the transversal direction of the adhesive tape to push and cut. Therefore, the adhesive tape that is pushed and cut at the time of cutting does not tear in the longitudinal direction. Further, since the cut is formed at the center in the short direction of the pressure-sensitive adhesive tape to be pushed and cut, only the side edge portion is not cut as in Patent Document 4.
Further, in the pressure-sensitive adhesive tape of the present invention, since only one notch is involved in the cutting, the notches adjacent to each other along the short direction of the pressure-sensitive adhesive tape as in the perforated notch part in Patent Document 1 are used. There is no need to be close and easy to connect.
 さらに、粘着テープを押して切るために切れ込みを拡張させるには、切れ込みまたは、その周辺に局所的な強い力を加える必要がある。よって、指の先端や爪の部分で粘着テープの表面を押すことが必要である。さらに、押す場所も粘着テープの側縁部付近の表面を押すと粘着テープはよじれて力を逃がすために、粘着テープ中央を押したほうが力を加えやすい。よって、切れ込みは粘着テープの短手方向中央に配置する。また、粘着テープの任意の部分で切断できるように複数の切れ込みを長手方向に沿って間隔をあけ連続して配置する。  Furthermore, in order to expand the notch to press and cut the adhesive tape, it is necessary to apply a strong local force to the notch or its periphery. Therefore, it is necessary to press the surface of the adhesive tape with the tip of the finger or the nail portion. Furthermore, since the pressure-sensitive adhesive tape is twisted to release the force when the surface to be pressed is pressed near the side edge of the pressure-sensitive adhesive tape, it is easier to apply the force by pressing the center of the pressure-sensitive adhesive tape. Therefore, the cut is arranged at the center in the short direction of the adhesive tape. Further, a plurality of cuts are continuously arranged at intervals along the longitudinal direction so as to be cut at any part of the adhesive tape.
 なお、押して切る粘着テープには巻体からはがす時や使用時、製造時においても長手方向に対し引っ張る力が作用する。押して切る粘着テープにはこの引っ張る力によって切断されない引張強度と粘着テープ面を押すことで容易に切断できることが求められる。
 必要な引張強度や粘着テープの表面を押した場合の切断のしやすさは実際の利用場面や使用目的によって異なるが、押して切る粘着テープは切れ込みの角度α、切れ込みの長さによって調整ができることを以下に説明する。
It should be noted that a force that pulls in the longitudinal direction acts on the adhesive tape that is pushed and cut when it is peeled off from the wound body, used, or manufactured. The pressure-sensitive adhesive tape to be pushed and cut is required to have a tensile strength that is not cut by this pulling force and to be easily cut by pressing the pressure-sensitive adhesive tape surface.
The required tensile strength and ease of cutting when the surface of the adhesive tape is pressed differ depending on the actual use situation and purpose of use, but the adhesive tape to be pressed and cut can be adjusted by the angle of cut α and the length of the cut. This will be described below.
 本発明は切れ込みを拡張させることで粘着テープを切断する。しかし、切れ込みの角度αが0度の場合は、粘着テープを長手方向に引っ張っても、切れ込みが拡張されないため、引張強度はほとんど低下しない。切れ込みの長さが同じ場合においては、角度αの絶対値が0度から大きくなる、すなわち切れ込みの長手方向が粘着テープの短手方向と平行な状態に近づくにつれ、切れ込みが拡張されやすく引張強度は低下する。角度αの絶対値が90度の時、引張強度は最も低い。なお、後述の実験結果によれば、角度αの絶対値が90度の時と比較して、引張強度が有意に高くなり、かつ、切断できる範囲として、角度αは10度≦|α|≦60度であることが望ましい。
 なお、切れ込みの角度は、複数の切れ込みにおいて一定である必要はなく、切れ込み毎に異なっても良い。 
The present invention cuts the adhesive tape by expanding the cut. However, when the cut angle α is 0 degree, even if the adhesive tape is pulled in the longitudinal direction, the cut is not expanded, so that the tensile strength hardly decreases. In the case where the length of the cut is the same, the absolute value of the angle α increases from 0 degree, that is, as the longitudinal direction of the cut approaches a state parallel to the short direction of the adhesive tape, the cut is easily expanded and the tensile strength is descend. When the absolute value of the angle α is 90 degrees, the tensile strength is the lowest. In addition, according to the experimental results described later, the angle α is 10 degrees ≦ | α | ≦ as a range in which the tensile strength is significantly higher than that when the absolute value of the angle α is 90 degrees and can be cut. It is desirable to be 60 degrees.
In addition, the angle of a notch does not need to be constant in several notches, and may differ for every notch.
 一方、切れ込みの角度αが同じであれば、切れ込みの長さが長いほど拡張されやすいので切断しやすくなるが、長すぎると引張強度は低下する。逆に、切れ込みの長さが短いほど強くなる。切れ込みの角度αの絶対値が90度に近づくほど、引張強度を確保するには、切れ込みの長さを短くするしかないが、短すぎると切れ込みが拡張されにくく、本発明の特徴である一つの切れ込みを拡張させて切断することが困難になる。よって、具体的には、切れ込みの長さは0.3mm以上で3mm以下、好ましくは2mm以下であることが望ましい。その理由は、一般的なOPPフィルム等のテープでは、0.3mm未満の切れ込みでは切れ込みの拡張ができず、テープを変形させてしまい切ることは困難である一方、切れ込みが5mm程度になってしまうと、引張強度が大きく低下してしまうのである。さらに、切れ込みが長いと巻き体等から剥がす時に切れ込みの片側が剥がれても、もう片側が巻き体に残り、切れ込みの部分から裂け易くなる。特に、剥がす方向に対し、切れ込みの方向が90度に近いほど、このような現象が起こる。従って、0.3mm以上で3mm以下、好ましくは2mm以下が望ましいのである。さらに、2mm以下が好ましいのは、切れ込みの長さが0.3mm以上では切断が可能であるため、引張強度をテープの材料を選ばずに担保するにはなるべく短い寸法であることが望ましいためである。 On the other hand, if the notch angle α is the same, the longer the notch length is, the easier it is to be expanded and the easier it is to cut. Conversely, the shorter the cut length, the stronger. As the absolute value of the notch angle α approaches 90 degrees, in order to ensure the tensile strength, the length of the notch can only be shortened, but if it is too short, the notch is difficult to expand, and one of the characteristics of the present invention is It becomes difficult to extend the cut and cut. Therefore, specifically, the length of the notch is 0.3 mm or more and 3 mm or less, preferably 2 mm or less. The reason for this is that, with a tape such as a general OPP film, it is difficult to extend the cut with a cut of less than 0.3 mm, and it is difficult to deform and cut the tape, but the cut is about 5 mm. As a result, the tensile strength is greatly reduced. Furthermore, if the cut is long, even if one side of the cut is peeled off when it is peeled off from the wound body or the like, the other side remains on the wound body and is easily torn from the cut part. In particular, such a phenomenon occurs as the cut direction is closer to 90 degrees with respect to the peeling direction. Therefore, it is desirable that the thickness is 0.3 mm or more and 3 mm or less, preferably 2 mm or less. Furthermore, 2 mm or less is preferable because cutting is possible when the length of the cut is 0.3 mm or more, and therefore it is desirable that the dimensions be as short as possible to ensure the tensile strength without selecting the tape material. is there.
 押して切る粘着テープの帯状フィルム基材は幾らかの伸縮性があるため、切れ込みを押す位置が切れ込みから離れるほど切れ込みは拡張され難くなり、押して切る粘着テープが切断しにくくなる。このため、長手方向の切れ込み同士の間隔は狭いほうが良い。しかしながら、前述したように押して切る粘着テープの切断では、長手方向に切れることはないが、切れ込みの長手方向の間隔が狭すぎると、巻体から粘着テープを剥がすときなどの力により粘着テープの切れ込みが長手方向につながり縦切れすることがある。このような縦切れを防止するために、具体的には粘着テープの長手方向の切れ込みの間隔は、切れ込みの長さの1倍以上で、少なくとも2mm以上が望ましい。
 その理由は、切れ込みの長さよりも短い間隔では、粘着テープが長手方向に切れてしまい易く、いわゆる縦切れの状態となってしまうので、切れ込みの長さの1倍以上であることが望ましい。さらに、発明者による実験結果では、一般的なOPPテープ等の材質では、テープ幅を1mm幅と2mm幅に切って引張り試験を実施した結果、2mm幅では長く伸びて切れ難くなったため、切れ込みの長さが短い場合であっても、2mm程度の間隔があることが望ましいのである。
 ここで、長手方向の切れ込み同士の間隔とは、長手方向に隣接する切れ込みの端部と端部の長手方向の最短の間隔を指す。
Since the strip-like film base material of the pressure-sensitive adhesive tape to be pushed and cut has some elasticity, the cut becomes difficult to expand as the position where the cut is pushed away from the cut, and the pressure-sensitive adhesive tape to be pushed and cut becomes difficult to cut. For this reason, it is better that the interval between the cuts in the longitudinal direction is narrow. However, as described above, the pressure-sensitive adhesive tape is not cut in the longitudinal direction when it is cut. However, if the distance in the longitudinal direction of the cut is too narrow, the pressure-sensitive adhesive tape is cut by force such as when the pressure-sensitive adhesive tape is peeled off from the roll. May be connected in the longitudinal direction and cut vertically. In order to prevent such vertical cuts, specifically, the interval between the cuts in the longitudinal direction of the pressure-sensitive adhesive tape is not less than 1 times the cut length, and is preferably at least 2 mm.
The reason is that the adhesive tape is likely to be cut in the longitudinal direction at an interval shorter than the length of the cut and is in a so-called vertical cut state. Furthermore, in the experimental results by the inventor, with a general material such as OPP tape, the tape width was cut into 1 mm width and 2 mm width, and as a result of performing a tensile test, it became long and difficult to cut at 2 mm width. Even when the length is short, it is desirable that there is an interval of about 2 mm.
Here, the interval between the cuts in the longitudinal direction refers to the shortest interval in the longitudinal direction between the ends of the cuts adjacent to each other in the longitudinal direction.
 なお、複数の切れ込みが連続的に形成されることには、押して切る粘着テープの長手方向に沿って均等間隔をおいて形成されることのほか、複数の切れ込みが均等間隔をおいて形成されたのちに切れ込みのない一定長さ部分が連なり、さらにこの組み合わせが繰り返されるという場合も含まれる。このような切れ込みの連続的な形成により、任意に意図した位置で押して切る粘着テープが切断される。  In addition, in order to form a plurality of cuts continuously, in addition to being formed at equal intervals along the longitudinal direction of the pressure-sensitive adhesive tape to be pushed and cut, a plurality of cuts were formed at equal intervals. There is also a case where a portion of a certain length without a cut is connected and this combination is repeated. By continuous formation of such cuts, the adhesive tape that is arbitrarily pushed and cut at the intended position is cut.
 請求項1における切れ込みとは、フィルム基材の一部が単に厚さ方向に切れ込んでいる状態にあるものを指し、開口部がなく面積を有しないものをいう。よってフィルム基材の一部を故意に取り除いて形成したために一定の面積が形成されたものは含めないが、レーザー等による切り込み時や切り込み後にフィルム基材が縮小するなどして発生するわずかな面積の開口部は、請求項1における切れ込みに含める。また、貫通する切れ込みとは、フィルム基材を貫通したものをいうが、実際の切れ込みの形成時に発生するわずかに未貫通の切れ込みを排除するものではない。
 切れ込みの形は、直線状の他に曲線、突起物により形成される不定形のものを含む。
The notches in claim 1 refer to those in which a part of the film substrate is simply notched in the thickness direction, and means that there is no opening and no area. Therefore, it does not include those formed by deliberately removing a part of the film substrate, but it does not include those formed with a certain area, but a slight area generated when the film substrate shrinks when cutting with laser or the like The opening is included in the notch in claim 1. Moreover, although the notch which penetrates means what penetrated the film base material, it does not exclude the slightly unpenetrated notch generated when the actual notch is formed.
The shape of the cut includes not only a straight line but also an indeterminate form formed by a curve or a protrusion.
 切れ込みは、開口面積を有する穴と比べほとんど開口面積を有さないために、粘着層がフィルムの表面に漏出しにくい。従って、べたついたり汚れたりしにくい。また、汚れないことで切れ込みも目立つようにならないため、外観品質を維持できる。また、穴としてフィルム基材の一部を取り除いて形成すると、取り除いた基材の処理が必要になるので望ましくなく、切れ込みが望ましいのである。
 上記構成の押して切る粘着テープにおいては、切れ込みの長さ、切れ込みの角度、切れ込みの長手方向についての間隔を調整することにより、押して切る粘着テープの長手方向の引張強度と、押して切る粘着テープの切り易さが調整できる。なお、この引張強度及び切り易さは、使用目的、使用方法に適するよう調整される。
Since the cut has almost no opening area compared to a hole having an opening area, the adhesive layer is less likely to leak onto the surface of the film. Therefore, it is difficult to get sticky or dirty. In addition, the appearance quality can be maintained because the cuts do not become noticeable because they are not dirty. Further, if a part of the film base material is removed as a hole, it is not desirable because the removed base material needs to be processed, and a notch is desirable.
In the pressure-sensitive adhesive tape of the above configuration, by adjusting the length of the cut, the angle of the cut, and the interval in the longitudinal direction of the cut, the tensile strength in the longitudinal direction of the pressure-cut adhesive tape and the cutting of the pressure-sensitive adhesive tape to be cut Ease can be adjusted. The tensile strength and ease of cutting are adjusted to suit the purpose and method of use.
 次に、請求項2記載の発明は、請求項1記載の押して切る粘着テープにおいて、複数の貫通する切れ込みは、短手方向の中央に設けられる1列の配列に代えて、帯状フィルム基材の短手方向の中央から両側縁部までの長さの各2/3の範囲内に,帯状フィルム基材の長手方向に沿って間隔を空けて連続的に配置される複数列を形成し,これらの列同士は、切れ込みの長さの1.5倍以上で、少なくとも3mm以上の間隔を空けて設けられ、これらの複数列における切れ込みは互いに千鳥配列を形成し、さらに複数の貫通する切れ込みの列のうち,一部またはすべての列の複数の貫通する切れ込みにおいて,これら切れ込みの長手方向が帯状フィルム基材の長手方向に対し角度α(10度≦|α|≦60度)をもって形成されたことを特徴とする。 Next, the invention according to claim 2 is the pressure-sensitive adhesive tape according to claim 1, wherein the plurality of slits penetrated in place of the one-row arrangement provided in the center in the short direction. A plurality of rows that are continuously arranged at intervals along the longitudinal direction of the belt-like film base material are formed within the range of 2/3 of the length from the center in the short side direction to both side edges. Are arranged at intervals of at least 3 mm at least 1.5 times the length of the cuts, and the cuts in the plurality of rows form a staggered arrangement with each other, and a plurality of through rows of cuts Among these, in some or all of the plurality of through-cuts in the row, the longitudinal direction of these cuts was formed at an angle α (10 degrees ≦ | α | ≦ 60 degrees) with respect to the longitudinal direction of the strip-shaped film substrate. Features The
 押して切る粘着テープの短手方向の幅が広くなるにつれ、上から指先や爪で押す位置が中央付近からその周辺にばらつく可能性がある。
 また、帯状フィルム基材は幾らかの伸長性を持つため、力が作用した場所から離れるにつれ切れ込みを拡張させる力が弱くなる。よって、帯状フィルム基材の短手方向の中央から両側縁部までの長さの各2/3の範囲内に切れ込みの列を複数列配置することで、押す位置がばらついてもいずれかの切れ込みに十分な力が作用し安定的に切断することができる。なお、2/3の範囲内には略2/3の範囲内であるものも含まれる。
 さらに、切れ込みの列と列の間を指先や爪で押した場合は、角度αの絶対値が小さな場合でも切れ込みが拡張するので必要な引張強度を確保でき、かつ切断しやすい。 
また、両側縁部近くには切れ込みを配列しないため、請求項1の場合と同様に巻き体から粘着テープを剥がす時に側縁部のみが切れることがない。
 なお、帯状フィルム基材の短手方向の中央から両側縁部までの長さの各2/3の範囲内に,帯状フィルム基材の長手方向に沿って間隔を空けて連続的に配置される列とは、帯状フィルム基材の長手方向に平行な列以外に、帯状フィルム基材の短手方向の中央から両側縁部までの長さの各2/3の範囲内を蛇行する列も含める。
As the width of the adhesive tape that is pushed and cut increases in the short-side direction, the position of pressing with the fingertip or nail from above may vary from the vicinity of the center to the periphery.
In addition, since the belt-like film base material has some extensibility, the force for expanding the cut becomes weaker as the distance from the place where the force is applied. Therefore, by arranging multiple rows of notches within the range of 2/3 each of the length from the center in the short direction of the strip-shaped film base to both side edges, even if the pressing position varies, any of the notches Sufficient force can be applied to the surface to stably cut. In addition, what is in the range of about 2/3 is also included in the range of 2/3.
Further, when the space between the rows of cuts is pushed with a fingertip or a nail, the cuts are expanded even when the absolute value of the angle α is small, so that the necessary tensile strength can be ensured and it is easy to cut.
Since notches are not arranged near both side edges, only the side edges are not cut when the adhesive tape is peeled from the wound body as in the case of claim 1.
In addition, it arrange | positions continuously along the longitudinal direction of a strip | belt-shaped film base material in the range of each 2/3 of the length from the center of the transversal direction of a strip | belt-shaped film base material to a both-sides edge part. In addition to the row parallel to the longitudinal direction of the belt-like film substrate, the row includes a row meandering within the range of 2/3 each of the length from the center in the short direction of the belt-like film substrate to both side edges. .
 切れ込みの長手方向が前記帯状フィルム基材の長手方向に対し角度α(10度≦|α|≦60度)であれば、列によって異なる角度であっても良いし、切れ込みごとに角度αが異なっても良い。請求項1と同様に角度αの絶対値が小さくなるほど引張強度は低下しない。 If the longitudinal direction of the cut is an angle α (10 degrees ≦ | α | ≦ 60 degrees) with respect to the longitudinal direction of the strip-shaped film substrate, the angle may be different depending on the row, and the angle α is different for each cut. May be. As in the first aspect, the tensile strength does not decrease as the absolute value of the angle α decreases.
 帯状フィルム基材を上方から指先で押したときの押して切る粘着テープの切断の仕組みは請求項1と同様であり、1つの切れ込みしか関与しないので、粘着テープの短手方向にミシン目を形成する必要はない。押して切る際には、粘着テープの長手方向に引っ張る力により切れ込みの裂ける方向が両側側縁部に向かうため、ジグザグに長手方向に向かって切れることがない。また、裂ける方向を切れ込みの配置(切れ込み同士の間隔)や切れ込みの向き(角度α)でコントロールする必要がない。 The mechanism for cutting the adhesive tape when the band-shaped film substrate is pressed with the fingertip from above is the same as in the first aspect, and only one notch is involved, so a perforation is formed in the short direction of the adhesive tape. There is no need. When pushing and cutting, since the direction of tearing is directed to both side edges by the force of pulling in the longitudinal direction of the adhesive tape, it is not cut zigzag in the longitudinal direction. Moreover, it is not necessary to control the direction of tearing by the arrangement of notches (interval between notches) and the direction of the notches (angle α).
 切断時などに粘着テープの縦切れを防ぐために、同一列の粘着テープの長手方向の切れ込みの間隔は、具体的には、切れ込みの長さの1倍以上で、少なくとも2mm以上とすることが望ましい。
 さらに異なる列同士で千鳥配列に切れ込みを配置する場合は、巻体から粘着テープの切断端を剥がす際に意図しない切断が起きないように、切断端から最寄りの切れ込みの端部までの最短の間隔を2mm以上開けたほうが良い。このため、列とは無関係に長手方向の切れ込みの間隔は2mm以上開けることが望ましい。ただし、巻体から粘着テープの切断端を剥がすことがあまりないなど利用上問題がない場合はこの限りではない。
 列と列の間隔も、具体的には切れ込みの長さの1.5倍以上とし、さらに少なくとも3mm以上とすることが望ましい。これは、同一列に配置された場合と同様な理由に加えて、列と列の切れ込みがつながると粘着テープの切断に直結するため、列間での安全率を1.5倍としていることに他ならない。
 このように切れ込みの間隔や列の間隔を開けることで、巻体から粘着テープの切断端を剥がす時や切断時などに意図しない切断を起こしにくい。
In order to prevent the longitudinal cut of the adhesive tape at the time of cutting or the like, specifically, the interval between the longitudinal cuts of the adhesive tape in the same row is preferably at least 1 mm of the length of the cut and at least 2 mm or more. .
In addition, when placing cuts in a staggered arrangement between different rows, the shortest distance from the cut end to the nearest cut end to prevent unintentional cuts when peeling the cut end of the adhesive tape from the roll Should be opened 2mm or more. For this reason, it is desirable that the longitudinal notch interval be 2 mm or more regardless of the row. However, this does not apply when there is no problem in use, such as not often peeling the cut end of the adhesive tape from the roll.
Specifically, the distance between the rows is preferably 1.5 times or more of the length of the cut, and more preferably at least 3 mm. In addition to the same reason as in the case where they are arranged in the same row, if the cuts between the rows are connected, it leads directly to the cutting of the adhesive tape, so the safety factor between the rows is 1.5 times. There is nothing else.
In this way, by providing a notch interval or a row interval, unintentional cutting is unlikely to occur when the cut end of the adhesive tape is peeled off from the wound body or at the time of cutting.
 上記構成の押して切る粘着テープにおいては、切れ込みの列の数、列の間隔、切れ込みの長さ、切れ込みの角度、切れ込みの長手方向についての間隔を調整することにより、押して切る粘着テープの長手方向の引張強度と、押して切る粘着テープの切り易さが調整できる。なお、この引張強度及び切り易さは、使用目的、使用方法に適するよう調整される。 
 この他、請求項1に記載の押して切る粘着テープと同様の作用を有する。
In the pressure-sensitive adhesive tape of the above configuration, by adjusting the number of rows of cuts, the interval between rows, the length of the cuts, the angle of the cuts, and the intervals in the longitudinal direction of the cuts, You can adjust the tensile strength and ease of cutting the adhesive tape. The tensile strength and ease of cutting are adjusted to suit the purpose and method of use.
In addition, it has the same action as the pressure-sensitive adhesive tape of claim 1 for cutting.
 次に、請求項3記載の発明は、帯状フィルム基材の少なくとも一面に粘着層を備えた,押して切る粘着テープであって、長さが0.3mm以上かつ3mm以内であるミシン目又はミシン目集合が、帯状フィルム基材の短手方向の中央から両側縁部までの長さの各2/3の範囲に,帯状フィルム基材の長手方向に沿って,間隔を空けて連続的に配置され列を形成し、この列は1列または複数列設けられ、列同士は、ミシン目又はミシン目集合の長さの1.5倍以上で、少なくとも3mm以上の間隔を空けて設けられ、これらミシン目又はミシン目集合の長手方向が帯状フィルム基材の長手方向に対し角度α(10度≦|α|≦60度)をもって形成されることを特徴とする。 
 上記のミシン目とは、請求項1及び請求項2に記載の貫通する切れ込みに代えて微小な切れ込みが、貫通する切れ込みの長手方向と同方向の直線上に切れ込みと同じ長さに並ぶものをいう。
また、ミシン目集合とは、複数本の上記ミシン目が並列して1つの集合を形成するもので、その長さが0.3mm以上かつ3mm以内のものをいう。
 従って、押して切る粘着テープの上方から力が加えられると、ミシン目を形成する微小な切れ込み同士が連結(連続)し、貫通する切れ込みにほぼ等しい1つの切れ込みを形成する。その後の切れ方は請求項1、請求項2と同じである。
 よって、指先や爪による局所的な力をテープ面に加えることでミシン目とほぼ等しい1つの貫通した切れ込みが完成し、この切れ込みが拡張して粘着テープ両端の側縁に到達し切断されるという作用を有する。
 ミシン目を構成する切れ込みは微小であるため、粘着テープを長手方向に引っ張っても切れ込みが拡張し難い。このため、一本の切れ込みと比較すると、同じ長さのミシン目は強い引張強度を有する。 
Next, the invention described in claim 3 is a perforated or perforated adhesive tape having an adhesive layer on at least one surface of a belt-like film substrate, the length of which is 0.3 mm or more and 3 mm or less. The assembly is continuously arranged at intervals along the longitudinal direction of the belt-like film substrate in the range of 2/3 each of the length from the center in the short direction of the belt-like film substrate to both side edges. This row is provided with one or a plurality of rows, and the rows are provided at least 1.5 times the length of the perforation or perforation set and at least 3 mm apart. The longitudinal direction of the mesh or perforation set is formed with an angle α (10 degrees ≦ | α | ≦ 60 degrees) with respect to the longitudinal direction of the belt-like film substrate.
The perforation described above is such that a minute notch is arranged in the same length as the notch on a straight line in the same direction as the longitudinal direction of the notch penetrating instead of the notch penetrating according to claim 1 and claim 2. Say.
Further, the perforation set refers to a plurality of perforations forming one set in parallel and having a length of 0.3 mm or more and 3 mm or less.
Therefore, when a force is applied from above the adhesive tape to be pushed and cut, the fine cuts forming the perforation are connected (continuous) to form one cut substantially equal to the cut through. Subsequent cutting methods are the same as those in the first and second aspects.
Therefore, by applying a local force from the fingertip or nail to the tape surface, one through notch almost equal to the perforation is completed, and this notch expands to reach the side edges at both ends of the adhesive tape and is cut. Has an effect.
Since the cut forming the perforation is very small, it is difficult to expand the cut even if the adhesive tape is pulled in the longitudinal direction. For this reason, the perforation of the same length has a strong tensile strength as compared with a single notch.
 さらに、ミシン目集合の場合は、押して切る粘着テープに上方からの力を加えると、複数本のミシン目同士の間における微小な切れ込みも連結(連続)しやすくなり、一列の場合よりも切断しやすくなるという作用を有する。
 ただし、並列するミシン目の列数が多いほど、粘着テープの切断端の周辺では、切れずに残った微小な切れ込みも多くなるため、巻体から粘着テープの切断端を剥がす時に意図しない切れを起こしやすい。このため、粘着テープの使用方法に応じミシン目の列数を決めることとするが、列数は2列が望ましい。
In addition, in the case of perforation set, if a force from above is applied to the adhesive tape that is pushed and cut, the minute notches between the multiple perforations will be easily connected (continuous), and cut more than in the case of a single row. It has the effect of becoming easier.
However, as the number of perforated lines in parallel increases, the minute cuts that remain without being cut near the cut end of the adhesive tape also increase, so unintentional cuts may occur when peeling the cut end of the adhesive tape from the roll. Easy to wake up. For this reason, the number of rows of perforations is determined according to the usage method of the adhesive tape, but the number of rows is preferably two.
 このミシン目を形成する微小な切れ込み同士の間隔及び複数本の並列するミシン目同士の間隔は押して切る粘着テープに上方から局所的な力が加わると容易に切断可能な間隔とする。 The intervals between the minute notches forming the perforations and the intervals between the plurality of parallel perforations are such that they can be easily cut when a local force is applied from above to the pressure-sensitive adhesive tape.
 さらに、請求項4記載の発明は、請求項1乃至請求項3のいずれか1項に記載の押して切る粘着テープにおいて、帯状フィルム基材は、切れ込み又はミシン目又はミシン目集合を含む一部に粘着層を備えない部分を持つことを特徴とする。
 一時的な物品の固定に粘着テープを用いる場合、固定の解除は粘着テープを切断するか、粘着テープを物品から剥ぎとることが必要になる。
 一時的な固定に押して切る粘着テープを使用した場合は、切れ込み、ミシン目、ミシン目集合及びそれらの周辺部が他の物に粘着していると、力を加えても切れ込みが拡張しないため切断できない。しかし、帯状フィルム基材の切れ込みを含む一部に粘着層を備えない部分を持つことで、爪や指先などで力を加えると切れ込みが拡張し、粘着テープが裂け易くなる。さらに、切れ込みが拡張した方向にも粘着層を備えないほうが粘着テープを切断しやすいため、切れ込み及び側縁部までを含むその周辺部に粘着層を備えない部分があっても良い。反対に、押して切る粘着テープの用途によっては完全な切断が不要な場合もあるため、一部の切れ込みや側縁部を含むその周辺部が粘着層を備えても良い。
Further, the invention according to claim 4 is the pressure-sensitive adhesive tape according to any one of claims 1 to 3, wherein the strip-shaped film base material is a part including notches, perforations, or perforated aggregates. It has the part which is not provided with the adhesion layer.
When an adhesive tape is used for temporarily fixing an article, releasing the fixation requires cutting the adhesive tape or peeling the adhesive tape from the article.
When using adhesive tape to cut by pressing for temporary fixing, if the notch, perforation, perforation assembly and their peripheral parts are sticking to other objects, the notch will not expand even if force is applied. Can not. However, by having a portion that does not include the adhesive layer in a part including the cut of the belt-shaped film substrate, the cut is expanded when a force is applied with a nail or a fingertip, and the adhesive tape is easily torn. Furthermore, since it is easier to cut the adhesive tape if the adhesive layer is not provided in the direction in which the cut is expanded, there may be a portion not provided with the adhesive layer in the peripheral portion including the cut and the side edge. On the contrary, since the complete cutting may not be necessary depending on the use of the pressure-sensitive adhesive tape to be pushed and cut, the peripheral portion including a part of the cuts and the side edges may be provided with an adhesive layer.
 帯状フィルム基材への粘着層の塗布は、例えば粘着テープの長手方向に沿って、短手方向の幅の半分程度まで塗布するほうが粘着テープを製造しやすい。このような場合の、短手方向中央部から左右に2列の切れ込みを持つ粘着テープでは、一列は結束するものに粘着するため切れ込みが拡張せず切断されない。このように粘着層を備えることで切断されない場合は、切れ込みを備える意味が乏しいことから切れ込みを省略してもよい。 
 一時的な物品の固定の解除として、粘着テープを物品から剥ぎとる場合は、切断端の周辺部に粘着層がないと物品に粘着していないので、この部分を掴み剥がしやすい。物品の固定に必要な粘着テープの長さが予めわかっている場合は、必要な長さごと、あるいは一定の長さごとに切れ込みを設けこの切れ込み及び切れ込み周辺部から片側または両側側端部まで粘着層を備えないことで実現できる。
 この他、請求項1乃至請求項3のいずれか1項に記載の押して切る粘着テープと同様の作用を有する。 
The application of the adhesive layer to the belt-shaped film substrate is easier to produce the adhesive tape, for example, by applying up to about half the width in the short direction along the longitudinal direction of the adhesive tape. In such a case, in the adhesive tape having two rows of cuts on the left and right sides from the central portion in the short direction, the cuts do not expand and are not cut because one row sticks to what is bound. Thus, when it does not cut | disconnect by providing an adhesion layer, you may abbreviate | omit a notch from the meaning with which a notch is provided.
When the adhesive tape is peeled off from the article as a temporary release of the article, it is not adhered to the article unless there is an adhesive layer around the cut end, and this part is easily grasped and peeled off. If the length of the adhesive tape required for fixing the article is known in advance, cuts are made for each required length or for a certain length, and adhesive is applied from the notch and the periphery of the cut to one or both sides. This can be achieved by not providing a layer.
In addition, it has the same action as the pressure-sensitive adhesive tape of any one of claims 1 to 3.
 本発明の請求項1記載の押して切る粘着テープにおいては、押して切る粘着テープの中央付近にテープ面に対して上方から指先や爪などによる集中した力が加えられると中央に配列された切れ込みの一つが側縁部に向け伸長し粘着テープは切断される。このため切断時に粘着テープが長手方向に裂けにくいという効果を有する。
 また、切断時の操作も粘着テープの短手方向中央部付近を指の先端部分か爪の部分で押すだけなので、子供でも片手で行うことができる。
 さらに、切断時に粘着テープの粘着層に指が触れないため、切断後にテープが指に付着し、不快な思いをすることや絡んで使用不能となること、指紋の跡が粘着テープに残ることがない。
 また、粘着テープを例えば巻体から剥がす時などの切断時以外においても、切れ込みが粘着テープ短手方向の中央付近にあることから、側縁部のみが切れることがない。
 さらに、使用目的により粘着テープに求められる引張強度と切断のしやすさは異なるが、粘着テープのフィルムの材質や厚さを考慮したうえで、切れ込みの長さと切れ込みの角度αを調整することで必要な引張強度と切断のしやすさを確保できる。例えば、後述する図3(a)に示すように、角度αを小さくしても必要な引張強度を確保しながら切れ込みの長さを長くすることができるので、切れ込みからやや離れた位置を押した場合でも粘着テープの切断が可能である。このため、単位面積当たりの切れ込みの数を少なくできる。このように、押して切る粘着テープは様々な構成とすることができるので、汎用性が高い。また、押して切る粘着テープの切れ込みは小さく、開口面積がほとんどないため、外観上も優れている。
 加えて、切れ込み同士の間隔を調整することで、粘着テープを特定の位置において切断できることから、産業利用で常に一定長さで使用するといった用途において、経費削減や製品の均一化に貢献することができる。
 また、押して切る粘着テープは、切れ込み付近への局所的な力で極めて容易に粘着テープを切断可能である反面、輸送中や取り扱い中に粘着テープに面的な力が加わった場合は、切れ込みがあまり拡張しないため粘着テープは切れにくい。また、切れ込み付近以外に局所的な力が加わった場合も同様である。さらに、粘着テープの側縁部に力が加わった場合は、テープがねじれて力を逃がすことから、粘着テープは切れにくい。このため、本発明の押して切る粘着テープは、容器の蓋の一時的な固定や食品パックを束ねる時の粘着テープに適する。
In the pressure-sensitive adhesive tape according to claim 1 of the present invention, when a concentrated force from above is applied to the tape surface near the center of the pressure-cut adhesive tape by a fingertip, a nail or the like, one of the cuts arranged in the center. One stretches toward the side edge and the adhesive tape is cut. For this reason, it has the effect that it is hard to tear an adhesive tape to a longitudinal direction at the time of a cutting | disconnection.
In addition, since the operation at the time of cutting is simply performed by pressing the vicinity of the center of the adhesive tape in the short direction with the tip of the finger or the nail, even a child can perform it with one hand.
In addition, since the finger does not touch the adhesive layer of the adhesive tape at the time of cutting, the tape may adhere to the finger after cutting, making it uncomfortable or entangled, and leaving fingerprint marks on the adhesive tape Absent.
Further, even when the adhesive tape is not cut, such as when the adhesive tape is peeled off from the wound body, since the cut is near the center in the short direction of the adhesive tape, only the side edge portion is not cut.
Furthermore, although the tensile strength required for adhesive tapes and the ease of cutting differ depending on the purpose of use, the length and the angle α of the notch can be adjusted by considering the material and thickness of the adhesive tape film. Necessary tensile strength and ease of cutting can be secured. For example, as shown in FIG. 3A to be described later, since the length of the cut can be increased while ensuring the necessary tensile strength even if the angle α is reduced, a position slightly away from the cut is pushed. Even in this case, the adhesive tape can be cut. For this reason, the number of notches per unit area can be reduced. In this way, the pressure-sensitive adhesive tape that is pushed and cut can have various configurations, and thus has high versatility. In addition, the pressure-sensitive adhesive tape has a small cut and has almost no opening area, so it is excellent in appearance.
In addition, since the adhesive tape can be cut at a specific position by adjusting the interval between the cuts, it can contribute to cost reduction and product uniformity in applications such as always using a fixed length for industrial use. it can.
In addition, the pressure-sensitive adhesive tape can be cut very easily with local force in the vicinity of the cut, but on the other hand, if surface pressure is applied to the pressure-sensitive adhesive tape during transportation or handling, the cut will not occur. The adhesive tape is difficult to cut because it does not expand so much. The same applies when a local force is applied in addition to the vicinity of the notch. Furthermore, when a force is applied to the side edge portion of the adhesive tape, the tape is twisted to release the force, so that the adhesive tape is difficult to cut. For this reason, the pressure-sensitive adhesive tape of the present invention is suitable for temporarily fixing the lid of the container or for bundling food packs.
 本発明の請求項2記載の押して切る粘着テープにおいては、複数列のうちのいずれかの切れ込みに力が作用することから、短手方向の長さが24mmの幅の広い粘着テープでも安定的に切断することができる。 
 押して切る粘着テープを一時的な固定に用いた場合には、開封が容易になる。例えば、ダンボール箱の封緘に押して切る粘着テープを用いると蓋と本体、蓋同士が固定される。開封する場合は、蓋と本体の間の隙間に位置する切れ込み周辺を爪でこするだけでいずれかの切れ込みから裂け始め、蓋と本体を分離することができる。続いて、蓋同士の合わせ目周辺も同様に行うことで、蓋を容易に開封することができる。
 この他、請求項1に記載の押して切る粘着テープと同様の有利な効果を有する。 
In the pressure-sensitive adhesive tape according to claim 2 of the present invention, since force acts on any one of the plurality of rows, even a wide pressure-sensitive adhesive tape having a width of 24 mm in the short direction is stable. Can be cut.
When the pressure-sensitive adhesive tape that is pushed and cut is used for temporary fixing, opening is facilitated. For example, when an adhesive tape that is pushed and cut to seal a cardboard box is used, the lid, the main body, and the lid are fixed. In the case of opening, the lid and the main body can be separated by starting to tear from any of the cuts by simply rubbing the periphery of the cut located in the gap between the lid and the main body with a nail. Subsequently, the lid can be easily opened by similarly performing the periphery of the joint between the lids.
In addition, the same advantageous effects as those of the pressure-sensitive adhesive tape to be pressed and cut according to claim 1 are obtained.
 本発明の請求項3記載の押して切る粘着テープにおいては、ミシン目を形成する微小な切れ込み同士を連結させるために力が必要であることから、貫通した1つの切れ込みを備える粘着テープと比較すれば、切断容易性がわずかに低下するものの、粘着テープ自身の引張強度を向上させることができる。
 また、ミシン目状に連続する切れ込みの集合は、くさび形にとがった先端を持つ細い針等を帯状フィルム基材に貫通させ形成できるので、加工作業が容易になり製造上のメリットが大きい。さらに外観に与える影響も小さい。
In the pressure-sensitive adhesive tape according to claim 3 of the present invention, since a force is required to connect the minute cuts forming the perforation, compared with a pressure-sensitive adhesive tape having a single cut through. Although the ease of cutting slightly decreases, the tensile strength of the adhesive tape itself can be improved.
In addition, a set of notches that are continuous in a perforated shape can be formed by penetrating a thin film needle having a wedge-shaped tip or the like through the belt-like film base material, which facilitates processing operations and has a great merit in manufacturing. Furthermore, the effect on the appearance is small.
  本発明の請求項4記載の押して切る粘着テープを一時的な固定に用いた場合、固定の解除は、粘着テープを切断するか、粘着テープを剥ぎとることが必要になる。粘着テープの切断においては、切れ込みやミシン目又はミシン目集合を含む一部に粘着層を持たないため切断しやすい。例えば、結束用テープに利用した場合、切断時に切れ込み周辺に粘着層があると切断したい部分が商品などに粘着し、切れ込みが拡張せず切断することが困難な場合がある。しかし、請求項4記載の押して切る粘着テープにおいては、切れ込みを含む一部に粘着層がないため、容易に切断の契機となる切れ込みの拡張が可能である。また、長手方向に沿って部分的に粘着層を持たない部分を作ることで、特定の意図した場所での切断が可能になる。また、切断に用いる切れ込みや上記ミシン目などの周辺が粘着層を持たない場合は、切断端の周辺部が物品に粘着していないので、この部分を掴み剥がしやすい。
 さらに、切れ込みや上記ミシン目などを含む一部に粘着層を備えない部分を持つ押して切る粘着テープは、切れ込みから粘着物質がテープ表面ににじみ出ることがなく、外観品質を高く保つことができる。 
 この他、請求項1乃至請求項3のいずれか1項に記載の押して切る粘着テープと同様の有利な効果を有する。 
When the pressure-sensitive adhesive tape to be pressed and cut according to claim 4 of the present invention is used for temporary fixation, it is necessary to release the fixation by cutting the adhesive tape or removing the adhesive tape. In the cutting of the adhesive tape, it is easy to cut because it does not have an adhesive layer in a part including notches, perforations or perforated aggregates. For example, when used as a binding tape, if there is an adhesive layer around the cut at the time of cutting, the part to be cut may stick to the product and the cut does not expand and it may be difficult to cut. However, in the pressure-sensitive adhesive tape to be cut and pressed according to claim 4, since there is no adhesive layer in a part including the cut, the cut can be easily expanded as a trigger for cutting. Moreover, the cutting | disconnection in a specific intended place is attained by making the part which does not have an adhesive layer partially along a longitudinal direction. Moreover, when the periphery of the cut used for cutting or the perforation does not have an adhesive layer, the peripheral portion of the cut end is not adhered to the article, so that this portion is easily grasped and peeled off.
Furthermore, the pressure-sensitive adhesive tape that has a portion that does not have an adhesive layer, such as a cut and the perforation, can keep the appearance quality high without causing the adhesive material to ooze out from the cut.
In addition, it has an advantageous effect similar to that of the pressure-sensitive adhesive tape to be pressed and cut according to any one of claims 1 to 3.
 以上より、これまで述べた構成を持つ本発明は、必要な引張強度を確保した上で、粘着層に触れずに粘着テープを切断可能である。しかも、粘着テープの側縁部のみが切断されることがない上に、ハサミ等の器具を用いないで簡単に切断することができる。従って、切断時にストレスがなく不快感がない。また、切れ込みが小さく目立たないことから、外観や印刷に与える影響が小さい。さらに、引張強度と切断のしやすさが調整可能であるために、物品の一時的な固定場面で特に貢献できる。  As described above, the present invention having the above-described configuration can cut the adhesive tape without touching the adhesive layer while ensuring the necessary tensile strength. And only the side edge part of an adhesive tape is not cut | disconnected, but it can cut | disconnect easily, without using instruments, such as scissors. Therefore, there is no stress and no discomfort during cutting. Further, since the cuts are small and unnoticeable, the influence on the appearance and printing is small. Furthermore, since the tensile strength and the ease of cutting can be adjusted, it can contribute particularly in the temporary fixing scene of the article.

 図2(b)は、粘着テープ1bに備えられる切れ込み3bが、粘着テープ1bの長手方向に沿って2列に亘って連続して設けられる場合を示しており、2列に亘って設けられた切れ込み3b間の間隔を説明するための模式図である。図2(b)において、bは同じ列の長手方向の切れ込み3bの間隔、cは切れ込み3bの2つの列の間隔、dは互いに異なる列に存在する切れ込み3bの上端と下端の長手方向の間隔、eは互いに異なる列に存在する切れ込み3bの上端と上端の長手方向の間隔である。この切れ込み3bの位置関係は、図中に示される最短距離b,c,d,eをもって表現される。例えば、e=0、すなわちフィルム基材2の短手方向に水平に配置される場合は、切れ込み3bは並行配列であり、これ以外は千鳥配列である。なお、図2(b)において、粘着テープ1bの上端は押して切った時の切断端を示している。
 次に、具体的な切れ込みの角度と引張強度、切れ易さの関係の測定結果を説明する。
FIG. 2A and FIG. 2B are enlarged views of the cut of the adhesive tape according to the present invention, respectively.
As shown in FIG. 2A, the notch 3a having the length a provided in the adhesive tape 1a is provided with an angle α. The angle α is an angle formed by the longitudinal direction of the cut 3a and the longitudinal direction of the adhesive tape 1a. When the longitudinal direction of the cut 3 is parallel to the longitudinal direction of the adhesive tape 1a, the angle α is 0 degrees and parallel to the short direction. A certain case is set to 90 degrees or -90 degrees. In addition, the sign of the angle α is indicated by plus when the clock is clockwise and minus when it is counterclockwise.
FIG.2 (b) has shown the case where the notch 3b with which the adhesive tape 1b is equipped is provided continuously over 2 rows along the longitudinal direction of the adhesive tape 1b, and was provided over 2 rows. It is a schematic diagram for demonstrating the space | interval between the notches 3b. In FIG. 2 (b), b is the distance between the longitudinal cuts 3b in the same row, c is the distance between the two rows of the cut 3b, and d is the longitudinal distance between the upper and lower ends of the cuts 3b existing in different rows. , E is the distance in the longitudinal direction between the upper end and the upper end of the notches 3b existing in different rows. The positional relationship of the notches 3b is expressed by the shortest distances b, c, d, and e shown in the drawing. For example, when e = 0, that is, when the film substrate 2 is horizontally disposed in the lateral direction, the cuts 3b are in a parallel arrangement, and the others are in a staggered arrangement. In addition, in FIG.2 (b), the upper end of the adhesive tape 1b has shown the cut end when it cuts by pushing.
Next, specific measurement results of the relationship between the notch angle, tensile strength, and ease of breaking will be described.
 図3(a)及び図3(b)は、それぞれOPPフィルム及びセロハンテープにおける引張強度と切れ込み角度の関係を示すグラフである。
 ここで、引張強度とは、粘着テープを長手方向に引っ張った時の切れにくさをいう。測定では、市販の幅18mmのOPP製粘着テープと幅20mmのセロハンテープを用いて、粘着テープの切断時の荷重(g)を引張強度とした。なお、測定は切れ込みの角度αを変えて行った。以下に、具体的な測定方法について詳細に述べる。
FIG. 3A and FIG. 3B are graphs showing the relationship between the tensile strength and the cutting angle in the OPP film and the cellophane tape, respectively.
Here, the tensile strength refers to the difficulty of breaking when the adhesive tape is pulled in the longitudinal direction. In the measurement, a commercially available OPP adhesive tape having a width of 18 mm and a cellophane tape having a width of 20 mm were used, and the load (g) at the time of cutting the adhesive tape was taken as the tensile strength. The measurement was performed by changing the cut angle α. A specific measurement method will be described in detail below.
 切れ込みは、所定の長さとなるように細工用カッターナイフを用い鉄製の定規の上で形成した。鉄製の定規には薄く油脂を塗ってテープを剥がす際に、テープが定規に粘着し切れ込みが拡大しないようにした。
 切れ込みはテープの短手方向中央に1箇所形成した。このテープの一端を水平においた淵の丸い板に固定し、他端を鉛直に垂らす。鉛直に垂らした粘着テープの端末部は円柱の周面に貼付した。円柱とテープを固定した板までの間隔は4cm程度とした。この円柱にバネばかりと補助おもりをぶら下げ、バネばかりを鉛直方向になるべく一定の速さで引き下げる。粘着テープが切断されるとバネばかりの目盛が0に戻るが、記録紙をバネばかりの目盛に挟むことで、切断直前の最大値を記録した。切れ込みの角度αは10度もしくは20度から90度までの10度ごとに変化させ、同一の切れ込みの角度で7回から25回繰り返し最大値を計測した。この最大値に補助おもりの重さや円柱の重さを加算した値をグラム単位で表し引張強度の測定値とした。
The cut was formed on an iron ruler using a craft cutter knife so as to have a predetermined length. When applying a thin oil and fat to the iron ruler and peeling off the tape, the tape sticks to the ruler so that the cut does not expand.
One notch was formed at the center in the short direction of the tape. One end of this tape is fixed to a round plate with a horizontal plate, and the other end is hung vertically. The end part of the adhesive tape hanging vertically was stuck on the peripheral surface of the cylinder. The distance to the plate on which the cylinder and the tape were fixed was about 4 cm. The spring and auxiliary weight are hung on this cylinder, and the spring is pulled down at a constant speed in the vertical direction. When the adhesive tape is cut, the scale of only the spring returns to 0, but the maximum value just before cutting was recorded by sandwiching the recording paper with the scale of only the spring. The cut angle α was changed every 10 degrees from 10 degrees or 20 degrees to 90 degrees, and the maximum value was repeatedly measured 7 to 25 times at the same cut angle. A value obtained by adding the weight of the auxiliary weight and the weight of the cylinder to the maximum value was expressed in grams and used as a measurement value of tensile strength.
 上記測定による測定結果は、図3乃至図5に示されるとおりである。それぞれ、横軸は切れ込みの角度α(度)を示し、縦軸は引張強度(g)を示す。
 まず図3(a)は、切れ込みの長さが1mmのOPPフィルムと5mmのOPPフィルムに関する切れ込みの角度ごとの引張強度の測定値の平均値を示す図である。この図において、切れ込みの長さが1mmの場合では、角度αが90度において1441(g)の引張強度となっている。そして、長さが5mmの場合では、角度αが20度において同程度の引張強度となっている。すなわち、角度αを小さくしても、切れ込みの長さを長くすることで同程度の引張強度を確保することができる。
 図3(b)は、切れ込みの長さが2mmのセロハンテープに関する切れ込みの角度ごとの引張強度の測定値の平均値を示す図である。測定値の統計値を表1に示した。
The measurement result by the said measurement is as FIG. 3 thru | or FIG. In each case, the horizontal axis indicates the angle of cut α (degrees), and the vertical axis indicates the tensile strength (g).
First, FIG. 3 (a) is a diagram showing an average value of measured values of tensile strength for each notch angle with respect to an OPP film having a notch length of 1 mm and an OPP film having a notch length of 5 mm. In this figure, when the cut length is 1 mm, the tensile strength is 1441 (g) when the angle α is 90 degrees. When the length is 5 mm, the tensile strength is comparable when the angle α is 20 degrees. That is, even if the angle α is reduced, the same tensile strength can be ensured by increasing the length of the cut.
FIG.3 (b) is a figure which shows the average value of the measured value of the tensile strength for every angle of a notch regarding the cellophane tape whose notch length is 2 mm. The statistical values of the measured values are shown in Table 1.

 次に、図4(a)乃至図4(c)は、それぞれ切れ込みの長さが1mmのOPPフィルム、切れ込みの長さが5mmのOPPフィルム、切れ込みの長さが2mmのセロハンテープにおける引張強度の測定値と切れ込み角度の関係を示す図である。
 これらの図は、図3(a)及び図3(b)と同一の測定結果を示した図であり、表1に示した統計値を加味し、より詳細な測定結果を示したものである。
 図4(a)乃至図4(c)では、箱ひげ図と平均の菱形を付して測定値を表した。
 箱ひげ図は、四角形の箱の上端と下端が分位点の25%と75%を示し、箱内の横線が中央値メディアンを示す。箱から上下に伸びる線をひげという。箱ひげ図は測定値の分布を示すもので、正規分布の場合は中央値メディアンを挟んで四角形の箱の上端と下端及び分位点の25%と75%の位置が等間隔に並ぶ。ひげから離れた測定値は外れ値となる。箱ひげ図から測定値は概ね正規分布から大きく外れていないため、平均値を代表値とすることができる。平均の菱形の中央横線は標本平均を示し、菱形の上下端の間はその95%信頼区間を示す。菱形の横幅は標本数を表す(具体的な標本数は表1を参照)。菱形が同じ引張強度にあれば平均値に差がないことがわかる。
 図3(a),図4(a),図4(b)及び表1より、OPPフィルムにおいては、切れ込みの長さaが短くなるほど粘着テープの引張強度は高くなる。
 また、図3(a),図3(b),図4(a),図4(b),図4(c)及び表1より、OPPフィルム及びセロハンテープのいずれにおいても、切れ込みの角度αが小さくなるほど引張強度は強くなる。
Next, FIGS. 4 (a) to 4 (c) show the tensile strengths of an OPP film having a cut length of 1 mm, an OPP film having a cut length of 5 mm, and a cellophane tape having a cut length of 2 mm, respectively. It is a figure which shows the relationship between a measured value and a notch angle.
These figures show the same measurement results as in FIGS. 3 (a) and 3 (b), and show the more detailed measurement results with the statistical values shown in Table 1. .
In FIG. 4 (a) to FIG. 4 (c), the measured values are represented by attaching a box plot and an average rhombus.
In the boxplot, the upper and lower ends of a rectangular box indicate 25% and 75% of the quantile, and the horizontal line in the box indicates the median median. A line extending up and down from the box is called a beard. The box-and-whisker plot shows the distribution of measured values. In the case of a normal distribution, the upper and lower ends of a rectangular box and the positions of 25% and 75% of quantiles are arranged at equal intervals across the median median. The measured value away from the whisker is an outlier. Since the measured values are not largely deviated from the normal distribution from the boxplot, the average value can be used as the representative value. The central horizontal line of the average diamond indicates the sample average, and the upper and lower ends of the diamond indicate the 95% confidence interval. The width of the diamond represents the number of samples (see Table 1 for specific sample numbers). It can be seen that there is no difference in the average value if the diamonds have the same tensile strength.
3A, FIG. 4A, FIG. 4B, and Table 1, in the OPP film, the tensile strength of the adhesive tape increases as the cut length a decreases.
Further, from FIG. 3A, FIG. 3B, FIG. 4A, FIG. 4B, FIG. 4C, and Table 1, in both the OPP film and the cellophane tape, the notch angle α The smaller the becomes, the stronger the tensile strength.
 しかしながら、切れ込み角度αが90度から60度までの引張強度は統計的に有意な差がない可能性が考えられる。これを検証するため、切れ込みの角度αが90度の時の引張強度と比較して有意差が出る90度以外の角度αを求めた。この検証は、Tukey-KramerのHSD検定により行った。この結果を以下の図5(a)乃至図5(c)において示す。
 図5(a)乃至図5(c)は、それぞれ切れ込みの長さが1mmのOPPフィルム、切れ込みの長さが5mmのOPPフィルム、切れ込みの長さが2mmのセロハンテープにおける引張強度と切れ込み角度の関係の測定値を示す図である。
 これらの図において、向かって右端に表示された円は、Tukey-KramerのHSD検定の結果を図示したもので、角度ごとに円が示され、円の中心はその角度の平均値を示す。円の大きさで最小有意差が示される。よって円が重なっていなければ危険率5%で平均値に有意な差があることを意味する。切れ込みの角度αが90度の引張強度の平均値と有意な差がある場合は、円が重ならず横軸ラベルの角度αを示す字体が斜字で示される。逆に、危険率5%で引張強度に統計的に有意な差がないと円が重なって示され、角度αも90度と同じ字体で示される。
  図5(a)に示した切れ込み1mmのOPPフィルムでは、切れ込み角度αが90度と80度では引張強度に有意な差が見られないが、70度以下では有意な差が見られた。また、図5(b)に示した切れ込み5mmのOPPフィルムでは、切れ込み角度αが90度と80度、70度では有意な差が見られないが60度では有意な差が見られた。さらに、図5(c)に示した切れ込み2mmのセロハンテープでは、切れ込み角度αが90度と80度では有意な差が見られないが70度以下では有意な差が見られた。
 以上から、切れ込みの角度αが60度以下では、90度に比べ引張強度が有意に高くなることが判明した。 
However, there is a possibility that there is no statistically significant difference in tensile strength when the cut angle α is 90 degrees to 60 degrees. In order to verify this, an angle α other than 90 degrees, in which a significant difference is obtained compared with the tensile strength when the cut angle α is 90 degrees, was obtained. This verification was performed by Tukey-Kramer HSD test. The results are shown in FIGS. 5 (a) to 5 (c) below.
FIGS. 5 (a) to 5 (c) show the tensile strength and cutting angle of an OPP film having a cut length of 1 mm, an OPP film having a cut length of 5 mm, and a cellophane tape having a cut length of 2 mm, respectively. It is a figure which shows the measured value of a relationship.
In these figures, the circle displayed at the right end is the result of Tukey-Kramer's HSD test. The circle is shown for each angle, and the center of the circle shows the average value of the angles. The smallest significant difference is indicated by the size of the circle. Therefore, if the circles do not overlap, it means that there is a significant difference in the average value with a risk rate of 5%. When the notch angle α is significantly different from the average value of the tensile strength of 90 degrees, the circles do not overlap and the font indicating the angle α of the horizontal axis label is shown in italics. On the contrary, when the risk rate is 5% and there is no statistically significant difference in tensile strength, the circles are overlapped, and the angle α is also indicated by the same font as 90 degrees.
In the OPP film having a 1 mm depth of cut shown in FIG. 5A, no significant difference was observed in tensile strength when the angle of cut α was 90 degrees and 80 degrees, but a significant difference was observed at 70 degrees or less. In the OPP film having a cut depth of 5 mm shown in FIG. 5B, no significant difference was observed when the cut angle α was 90 degrees, 80 degrees, and 70 degrees, but a significant difference was observed at 60 degrees. Furthermore, in the cellophane tape having a cut depth of 2 mm shown in FIG. 5C, no significant difference was observed when the cut angle α was 90 degrees and 80 degrees, but a significant difference was observed when the cut angle was 70 degrees or less.
From the above, it was found that when the cut angle α is 60 degrees or less, the tensile strength is significantly higher than that of 90 degrees.
 次に、表2に請求項1に対応する粘着テープを上から押した時の切断の容易さと切れ込みの角度の関係について示した。測定は、市販の18mmの幅のOPP製粘着テープと20mm幅のセロハンテープを用い、切れ込みの角度を10度ごとに変え測定した。測定は切れ込みの入った粘着テープの一方を固定し、一方を手で引っ張りながら粘着テープの切れ込みの近くを上から爪で押した。同一角度で複数回行い、押した時の切断の容易性を「良く切れる。」「切れる。」「切れにくい。」「切れない。」の4段階で評価した。
 表2に示すように、切れ込みの角度αが10度の場合は、20度に比べかなり切れにくくなっている。そして切れ込みの角度αが0度ではほとんど切れない状態になる。これらの結果から、切れ込み角度αが20度以下の場合では、切れ込み角度αが減少するほど粘着テープの切断の容易性が低下することがわかる。
Next, Table 2 shows the relationship between the ease of cutting and the angle of cut when the pressure-sensitive adhesive tape corresponding to claim 1 is pressed from above. The measurement was carried out by using a commercially available 18 mm wide OPP adhesive tape and a 20 mm wide cellophane tape, and changing the cut angle every 10 degrees. The measurement was carried out by fixing one of the cut adhesive tapes and pressing the top of the adhesive tape near the cut with a nail from above. The test was performed several times at the same angle, and the ease of cutting when pressed was evaluated in four stages: “cut well”, “cut”, “not easily cut”, and “not cut”.
As shown in Table 2, when the cut angle α is 10 degrees, it is considerably harder to cut than 20 degrees. When the cutting angle α is 0 degree, the cutting is almost impossible. From these results, it can be seen that when the cutting angle α is 20 degrees or less, the ease of cutting the adhesive tape decreases as the cutting angle α decreases.

 本発明の実施の形態に係る実施例1の粘着テープについて、図6乃至図9及び表3を用いて詳細に説明する(主に、請求項1に対応)。
 なお、図1乃至図2で示した構成要素については同一符号を付して、その説明を省略する。図6は実施例1に係る粘着テープの平面図、図7は同じくその利用例を示す図である。
 表3に実施例1に係る粘着テープ6の構成についてまとめる。表3における切れ込みの長さa,切れ込みの長手方向の間隔b,切れ込みの短手方向の間隔cは、図2(a)及び図2(b)に示したものである。なお、本例示により本願発明が制限されるものではない。
The adhesive tape of Example 1 according to the embodiment of the present invention will be described in detail with reference to FIGS. 6 to 9 and Table 3 (mainly corresponding to claim 1).
The components shown in FIGS. 1 and 2 are denoted by the same reference numerals and description thereof is omitted. FIG. 6 is a plan view of the pressure-sensitive adhesive tape according to Example 1, and FIG.
Table 3 summarizes the configuration of the adhesive tape 6 according to Example 1. The length a of the notch, the distance b in the longitudinal direction of the notch, and the distance c in the short direction of the notch in Table 3 are those shown in FIGS. 2 (a) and 2 (b). Note that the present invention is not limited by this illustration.

 図6に示すように、実施例1に係る粘着テープ6は、フィルム基材2の裏面に粘着層4を備え、複数の切れ込み7が設けられている。切れ込み7は長さa(図2(a)参照、以下同じ)が0.8mmであり、フィルム基材2の短手方向の中央に、粘着テープ6の長手方向に沿って3mmの均等間隔b(図2(b)参照、以下同じ)をおいて一列に設けられ、切れ込み配列8を形成する。フィルム基材2は、OPPを材質とした短手方向の長さが12mmのフィルムである。また、切れ込み7は角度αが30度をもって設けられる。
 切れ込み7は、粘着テープ6の厚さ方向に対しほぼ垂直に開けられ、その縦断面は線状である。その深さは、フィルム基材2の厚さとほぼ等しくフィルム基材2を貫通している(図示せず)。なお、図6において、粘着テープ6の上端は押して切った時の切断端を示している。
As shown in FIG. 6, the pressure-sensitive adhesive tape 6 according to Example 1 includes a pressure-sensitive adhesive layer 4 on the back surface of the film base 2 and is provided with a plurality of cuts 7. The notch 7 has a length a (see FIG. 2A, the same applies hereinafter) of 0.8 mm, and a uniform interval b of 3 mm along the longitudinal direction of the adhesive tape 6 in the center of the film base 2 in the short direction. (See FIG. 2 (b), the same applies hereinafter). The film base 2 is a film having a length of 12 mm in the short direction made of OPP. Further, the cut 7 is provided with an angle α of 30 degrees.
The notch 7 is opened substantially perpendicularly to the thickness direction of the adhesive tape 6 and its longitudinal section is linear. The depth is almost equal to the thickness of the film substrate 2 and penetrates the film substrate 2 (not shown). In addition, in FIG. 6, the upper end of the adhesive tape 6 has shown the cut end when it cuts by pushing.
 次に、実施例1に係る粘着テープ6の作用について説明する。
 実際に粘着テープ6を切断するには、粘着テープ6の長手方向における任意の部分を手で固定するか、または他の物体に貼付して固定し、巻体5(図示せず。図1(a)の符号5参照、以下同じ。)から剥がされた粘着テープ6の短手方向の中央付近を上方より指の先端部分か爪の部分で押す。すると、力が加わった周辺の切れ込み7には粘着テープ6の長手方向に引っ張る力が働き、切れ込み7が拡張する。力を加え続けることで切れ込み7はさらに拡張して粘着テープ6の両側縁部に向かって伸長し、粘着テープ6が切断される。
 また、複数の切れ込み7がフィルム基材2の長手方向に沿って一定間隔をおいて連続的に設けられることから、長手方向のいずれの位置において力を加えても粘着テープ6が切断されるという作用をももたらす。
 また、切れ込み7の長さを変化させると、粘着テープの引張強度と切れやすさが変化するという作用を有する。
Next, the effect | action of the adhesive tape 6 which concerns on Example 1 is demonstrated.
In order to actually cut the adhesive tape 6, an arbitrary portion in the longitudinal direction of the adhesive tape 6 is fixed by hand or attached to another object and fixed, and the wound body 5 (not shown in FIG. 1). Press the upper part of the adhesive tape 6 peeled off from the reference numeral 5 of a), and the same applies to the center in the short direction, with the tip or fingernail of the finger from above. Then, the pulling force in the longitudinal direction of the adhesive tape 6 acts on the peripheral cut 7 to which the force is applied, and the cut 7 expands. By continuing to apply force, the cut 7 is further expanded and extended toward both side edges of the adhesive tape 6, and the adhesive tape 6 is cut.
In addition, since the plurality of cuts 7 are continuously provided along the longitudinal direction of the film substrate 2 at a constant interval, the adhesive tape 6 is cut even if a force is applied at any position in the longitudinal direction. Also has an effect.
Moreover, when the length of the notch 7 is changed, it has the effect | action that the tensile strength of an adhesive tape and an easiness to cut change.
 次に、実施例1に係る粘着テープ6の効果について説明する。
 粘着テープ6は、指先や爪で押さえることのみで容易に切断できる。
 従来技術では、両手を用いて切断する必要があったが、粘着テープ6では極めて切断容易である点が特に優れている。また、粘着テープ6をフィルム基材2の側から押さえることから、粘着層4に指が触れずに切断可能である。よって、快適に使用できるとともに、指紋が粘着層4に残らず美観も優れたものとなる。さらに切断時や切断後に粘着テープが指に付着したり、絡んで使用不能となったりすることを防止できる。
 他にも、粘着テープ6がその長手方向に沿って裂け難いため、巻体5から粘着テープ6を剥がすときに意図しない切れ方をして粘着テープ6の一部が巻体5に残ることがない。 
 また、切れ込み7が粘着テープ6の短手方向の中央付近にあること、及び、切断端の近くに切れ込み7がないことから、例えば巻体5から粘着テープ6の切断端を剥がす時などに各側縁部のみが破断することや中央から縦切れすることがない。よって、所望の長さの粘着テープ6片を外観上も美しく採取できる。
 加えて、粘着テープ6の長手方向のいずれの位置においても粘着テープ6は切断されるため、利便性があり、必要以上の長さを切り取ることもないので、経済性もよい。
 また、切れ込み7の角度α、長さa、間隔bを調整することにより長手方向の引張強度と切りやすさを調整できる。よって、フィルム基材2の材質や使用目的、使用方法に合わせ引張強度と切りやすさを調整できるので、様々な仕様の粘着テープを製作可能であり、汎用性が高い。 
Next, the effect of the adhesive tape 6 according to Example 1 will be described.
The adhesive tape 6 can be easily cut only by pressing it with a fingertip or a nail.
In the prior art, it was necessary to cut with both hands, but the adhesive tape 6 is particularly excellent in that it is very easy to cut. Further, since the adhesive tape 6 is pressed from the film base 2 side, the adhesive tape 4 can be cut without touching the adhesive layer 4. Therefore, it can be used comfortably and the fingerprint is not left on the adhesive layer 4 and the aesthetic appearance is excellent. Further, it is possible to prevent the adhesive tape from adhering to the finger at the time of cutting or after cutting, or from becoming unusable due to tangling.
In addition, since the adhesive tape 6 is difficult to tear along the longitudinal direction, when the adhesive tape 6 is peeled off from the wound body 5, the adhesive tape 6 may be cut unintentionally and a part of the adhesive tape 6 remains on the wound body 5. Absent.
Moreover, since the notch 7 is near the center of the adhesive tape 6 in the short direction and there is no notch 7 near the cut end, for example, when the cut end of the adhesive tape 6 is peeled off from the wound body 5 Only the side edge portion is not broken or vertically cut from the center. Therefore, 6 pieces of adhesive tape having a desired length can be collected beautifully in appearance.
In addition, since the pressure-sensitive adhesive tape 6 is cut at any position in the longitudinal direction of the pressure-sensitive adhesive tape 6, there is convenience, and the length more than necessary is not cut off.
Further, the tensile strength in the longitudinal direction and the ease of cutting can be adjusted by adjusting the angle α, the length a, and the interval b of the notch 7. Therefore, since the tensile strength and ease of cutting can be adjusted in accordance with the material, purpose of use, and method of use of the film substrate 2, pressure-sensitive adhesive tapes of various specifications can be manufactured, and versatility is high.
 本実施例に係る粘着テープの切断の容易性は、巻体5から必要分を切り取る場合の他に、一時的な固定に用いた粘着テープを切断するような場合に特に便利である。
 次に、粘着テープ6の利用例について説明する。図7に示すように、粘着テープ6は、コンビニエンスストア等で販売される弁当などに用いられる容器本体9とその蓋9aを固定している。
 もちろん蓋を容器からはずす場合は、粘着テープ6の切断が必要であるが、容器よりも蓋が大きいため、容器本体9と蓋9aから離れている粘着テープ6の中心部分を上から指先や爪で押すと片手で簡単に切断できる。切断片は容器本体9に粘着して残るため手にまとわりつくことがなく開封に手間がかからない。また、テープの側縁部ではなく、テープ中心部に局所的な強い力が働かないと切断しないため、輸送中に粘着テープ6が不意に切断される可能性は小さく、一時的な固定にも適する粘着テープであると言える。
The ease of cutting of the pressure-sensitive adhesive tape according to the present embodiment is particularly convenient in the case of cutting the pressure-sensitive adhesive tape used for temporary fixation in addition to the case where a necessary portion is cut from the wound body 5.
Next, an application example of the adhesive tape 6 will be described. As shown in FIG. 7, the adhesive tape 6 fixes a container body 9 used for a lunch box sold at a convenience store or the like and its lid 9a.
Of course, when removing the lid from the container, it is necessary to cut the adhesive tape 6. However, since the lid is larger than the container, the central portion of the adhesive tape 6 that is separated from the container main body 9 and the lid 9a is placed on the fingertip or nail from above. It can be easily cut with one hand. Since the cut piece remains adhered to the container body 9, it does not cling to the hand and does not take time to open. In addition, the tape is not cut unless a strong local force is applied to the tape center instead of the side edge of the tape. It can be said that it is a suitable adhesive tape.
 次に、実施例1に係る第1の変形例について、図8を用いて説明する。図8は実施例1に係る粘着テープの第1の変形例の平面図である。
 図8に示すように、実施例1の第1の変形例に係る粘着テープ6aは、フィルム基材2に複数の切れ込み7aが設けられる。フィルム基材2は、セロハンを材質とした短手方向の長さが12mmのフィルムである。また、切れ込み7aは長さaが1.0mmである。なお、セロハンフィルムはOPPフィルムに比べ裂けにくいため、切れ込み7aの長さaは、切れ込み7の長さaよりも大きいものとした。
 そして、切れ込み7aの角度αは、30度及び-30度である。切れ込み7aにおいては、30度と-30度の角度αが交互に繰り返され、切れ込み配列8aが形成されている。その他の構成は、実施例1の粘着テープ6と同様である。
Next, a first modification according to the first embodiment will be described with reference to FIG. FIG. 8 is a plan view of a first modification of the adhesive tape according to the first embodiment.
As shown in FIG. 8, the adhesive tape 6 a according to the first modification of Example 1 is provided with a plurality of cuts 7 a in the film base 2. The film substrate 2 is a film having a length of 12 mm in the short direction made of cellophane. The cut 7a has a length a of 1.0 mm. Since the cellophane film is not easily torn compared to the OPP film, the length a of the cut 7a is set to be longer than the length a of the cut 7.
The angle α of the cut 7a is 30 degrees and −30 degrees. In the notches 7a, the angles α of 30 degrees and −30 degrees are alternately repeated to form the notch array 8a. Other configurations are the same as those of the adhesive tape 6 of the first embodiment.
 続いて、粘着テープ6aの作用及び効果について説明する。
 実施例1の第1の変形例である粘着テープ6aでは、切れ込み7aの角度αが交互に変わるために、中央付近から両端方向へ少し外れた位置を押しても、その位置に最も近接する切れ込み7aが拡張し、粘着テープ6aが切断されるという作用を有する。従って、短手方向の中央付近を押す場合と比較しても切断の容易性が大きく変わることがない。この点に関し、実施例1の粘着テープ6(図6参照)では、押す位置が短手方向の中央付近から向かって左側に外れた場合は、右側に外れた場合より切れ込み7が拡張し難くなって、若干切断しにくくなる可能性があった。粘着テープ6aでは、このような可能性はほとんどないことから、粘着テープ6に比べ安定的に切断できるという効果を有する。
 この他、実施例1の第1の変形例に係る粘着テープ6aは、実施例1に係る粘着テープ6と同様の作用及び効果を有する。なお、図8において、粘着テープ6aの上端は押して切った時の切断端を示している。
Then, the effect | action and effect of the adhesive tape 6a are demonstrated.
In the pressure-sensitive adhesive tape 6a which is the first modification of the first embodiment, the angle α of the cut 7a is alternately changed. Therefore, even when a position slightly deviated from the center toward both ends is pushed, the cut 7a closest to the position is pressed. Expands and the adhesive tape 6a is cut. Therefore, the ease of cutting does not change significantly even when compared with the case of pressing near the center in the short direction. In this regard, in the pressure-sensitive adhesive tape 6 of Example 1 (see FIG. 6), when the pressing position is deviated to the left from the center in the short direction, the cut 7 is more difficult to expand than when deviated to the right. Therefore, there is a possibility that it is difficult to cut. Since there is almost no such possibility in the adhesive tape 6a, it has the effect that it can cut | disconnect stably compared with the adhesive tape 6. FIG.
In addition, the pressure-sensitive adhesive tape 6a according to the first modification of the first embodiment has the same functions and effects as the pressure-sensitive adhesive tape 6 according to the first embodiment. In addition, in FIG. 8, the upper end of the adhesive tape 6a has shown the cut end when it cuts by pushing.
 次に、実施例1に係る第2の変形例について、図9を用いて説明する。図9は実施例1に係る粘着テープの第2の変形例の平面図である。
 図9に示すように、実施例1の第2の変形例に係る粘着テープ6bは、フィルム基材2に複数の切れ込み7bが設けられる。フィルム基材2は、アセテートを材質とした短手方向の長さが12mmのフィルムである。
 粘着テープ6bは、フィルム基材2に、複数(3個)の切れ込み7bが均等間隔をおいて連続したのち、切れ込み7bのない部分が一定長さで連なり、さらにこの組み合わせが繰り返された、一列からなる切れ込み配列8bを形成する。このとき、切れ込み7bの長さa及び間隔bは切れ込み7と同様であり、フィルム基材2を貫通する。切れ込み角度αは-30度である。また、切れ込み7bの長さa、個数及び切れ込み7bのない部分の長さは自在に変化される。
 さらに、3個連続した切れ込み7bのうち中央の切れ込み7bを挟んだ両側に、一ヶ所ずつ切れ込み位置マーク10が備えられる。なお、切れ込み位置マーク10は三角形状であるが、この形状のみに限られない。その他の構成は、実施例1の粘着テープ6と同様である。なお、図9において、粘着テープ6bの上端は押して切った時の切断端を示している。
Next, a second modification according to the first embodiment will be described with reference to FIG. FIG. 9 is a plan view of a second modification of the adhesive tape according to the first embodiment.
As shown in FIG. 9, the adhesive tape 6 b according to the second modification of Example 1 is provided with a plurality of cuts 7 b in the film base 2. The film substrate 2 is a film having a length of 12 mm in the short direction made of acetate.
The adhesive tape 6b is a line in which a plurality of (three) cuts 7b are continuous with the film substrate 2 at equal intervals, and then the portions without the cuts 7b are connected at a constant length, and this combination is repeated. A notch array 8b is formed. At this time, the length a and the interval b of the notches 7b are the same as those of the notches 7, and penetrate through the film base 2. The cut angle α is −30 degrees. Further, the length a and the number of the notches 7b and the length of the portion without the notches 7b can be freely changed.
Further, a cut position mark 10 is provided on each side of the three continuous cuts 7b across the central cut 7b. The cut position mark 10 has a triangular shape, but is not limited to this shape. Other configurations are the same as those of the adhesive tape 6 of the first embodiment. In addition, in FIG. 9, the upper end of the adhesive tape 6b has shown the cut end when it cuts by pushing.
 そして、粘着テープ6bの作用及び効果について説明する。
 実施例1の第2の変形例である粘着テープ6bでは、切れ込み7bが形成された位置を押すことで切断されるという作用を有するが、切れ込み7bのない部分を押すと切断されない。
 しかし、粘着テープ6bでは、切れ込み位置マーク10が設けられているので、これを押すことで常に切れ込み7bの周辺で切断が行われる。このため、粘着テープ6bを一定の長さに切断することができるという効果を有する。
 この他、実施例1の第2の変形例に係る粘着テープ6bは、実施例1に係る粘着テープ6と同様の作用及び効果を有する。
And the effect | action and effect of the adhesive tape 6b are demonstrated.
The pressure-sensitive adhesive tape 6b, which is the second modification of the first embodiment, has the effect of being cut by pressing the position where the cut 7b is formed, but is not cut when the portion without the cut 7b is pressed.
However, since the notch position mark 10 is provided on the adhesive tape 6b, cutting is always performed around the notch 7b by pressing this mark. For this reason, it has the effect that the adhesive tape 6b can be cut | disconnected by fixed length.
In addition, the pressure-sensitive adhesive tape 6b according to the second modification of the first embodiment has the same operations and effects as the pressure-sensitive adhesive tape 6 according to the first embodiment.
 なお、実施例1に係る粘着テープは、本実施例に示す構造に限定されるものではない。例えば、切れ込みの長さa及び間隔bは、表3に記載された以外の値でも良い。このとき、長さaは0.3mm以上で3mm以下であれば良く、2mm以下が好ましい。また、間隔bは、切れ込みの長さaの1倍以上で、少なくとも2mm以上であれば良い。
 これらの寸法に関する根拠については、既に課題を解決するための手段の欄で述べたとおりである。
In addition, the adhesive tape which concerns on Example 1 is not limited to the structure shown in a present Example. For example, the cut length a and the interval b may be values other than those described in Table 3. At this time, the length a may be 0.3 mm or more and 3 mm or less, and 2 mm or less is preferable. Further, the interval b may be at least 1 times the notch length a and at least 2 mm.
The basis for these dimensions has already been described in the section of means for solving the problem.
 本発明の実施の形態に係る実施例2の押して切る粘着テープについて、図10乃至図13及び表4を用いて詳細に説明する(主に、請求項2に対応)。
 なお、図1乃至図9で示した構成要素については同一符号を付して、その説明を省略する。
 以下に、実施例2に係る粘着テープ11の構成について図10及び表4を参照しながら具体的に述べる。図10は実施例2に係る粘着テープの平面図である。表4における切れ込みの長さa,切れ込みの長手方向の間隔b,切れ込みの短手方向の間隔c,互いに異なる列に存在する切れ込み3bの上端と下端の長手方向の間隔d,互いに異なる列に存在する切れ込み3bの上端と上端の長手方向の間隔eは、図2(b)に示したものである(以降、表5において同じ)。なお、本例示により本願発明が制限されるものではない。
The pressure-sensitive adhesive tape of Example 2 according to the embodiment of the present invention will be described in detail with reference to FIGS. 10 to 13 and Table 4 (mainly corresponding to claim 2).
The components shown in FIGS. 1 to 9 are denoted by the same reference numerals, and description thereof is omitted.

FIG. 10 is a plan view of the adhesive tape according to the second embodiment. In Table 4, the length a of the notch, the distance b in the longitudinal direction of the notch, the distance c in the short direction of the notch, the distance d in the longitudinal direction of the upper and lower ends of the notches 3b existing in different rows, present in different rows The distance e in the longitudinal direction between the upper end and the upper end of the cut 3b is as shown in FIG. 2B (hereinafter the same in Table 5). Note that the present invention is not limited by this illustration.

 図10に示すように、実施例2に係る粘着テープ11は、フィルム基材2に複数の切れ込み12が設けられ、切れ込み配列13を形成する。切れ込み配列13は、フィルム基材2の短手方向の中央から両側縁部までの長さの各2/3の範囲内に設けられる。
 フィルム基材2は、OPPを材質とした短手方向の長さが18mmのフィルムである。また、切れ込み12は長さaが0.8mmであり、フィルム基材2の短手方向の中央に、粘着テープ11の長手方向に沿って5mmの均等間隔bをおいて2列に設けられ、各列はフィルム基材2の短手方向中央から互いに遠ざかる方向へ3mmずつ離隔している。すなわち、間隔c(図2(b)参照、以下同じ)は6mmである。また、間隔d(図2(b)参照、以下同じ)は2.1mm、間隔e(図2(b)参照、以下同じ)は2.9mmであり、切れ込み配列13は千鳥配列である。
 また、切れ込み角度αは、図10の左側の列が10度、右側の列が-10度である。
 この他の構成は、実施例1に係る粘着テープ6と同様である。なお、図10において、粘着テープ11の上端は押して切った時の切断端を示している。
As shown in FIG. 10, the adhesive tape 11 according to Example 2 is provided with a plurality of cuts 12 in the film base 2 to form a cut array 13. The cut array 13 is provided in the range of 2/3 of the length from the center in the short direction of the film base 2 to both side edges.
The film substrate 2 is a film having a length of 18 mm in the short direction made of OPP. Further, the notches 12 have a length a of 0.8 mm, and are provided in two rows at an equal interval b of 5 mm along the longitudinal direction of the adhesive tape 11 at the center in the short direction of the film base 2. Each row is separated by 3 mm in the direction away from the center in the short direction of the film substrate 2. That is, the interval c (see FIG. 2B, the same applies hereinafter) is 6 mm. Further, the interval d (see FIG. 2B, the same applies hereinafter) is 2.1 mm, the interval e (see FIG. 2B, the same applies hereinafter) is 2.9 mm, and the notch array 13 is a staggered array.
Further, the cutting angle α is 10 degrees in the left column of FIG. 10 and −10 degrees in the right column.
Other configurations are the same as those of the adhesive tape 6 according to the first embodiment. In addition, in FIG. 10, the upper end of the adhesive tape 11 has shown the cut end when it cuts by pushing.
 次に、実施例2に係る粘着テープ11の作用について説明する。
 粘着テープ11は、2列の切れ込み12が備えられていることから、押さえる位置が粘着テープ11の短手方向の中央付近から両端側に外れても、押さえた位置の近くに切れ込み12があるため、切れ込み12が拡張し、その結果粘着テープ11が切断される。また、切れ込み配列13の列の間を上から押した場合においても、切れ込み12が拡張し同様に粘着テープ11が切断される。これは、切れ込みの角度αの絶対値が小さな値であっても同様である。
 この他、実施例2に係る粘着テープ11は、実施例1に係る粘着テープ6と同様の作用を有する。 
Next, the effect | action of the adhesive tape 11 which concerns on Example 2 is demonstrated.
Since the adhesive tape 11 is provided with two rows of cuts 12, even if the pressing position is deviated from the center in the short direction of the adhesive tape 11 to both ends, there are the cuts 12 near the pressed position. The notch 12 is expanded, and as a result, the adhesive tape 11 is cut. In addition, when the space between the rows of the cut array 13 is pushed from above, the cut 12 is expanded and the adhesive tape 11 is similarly cut. This is the same even if the absolute value of the notch angle α is small.
In addition, the pressure-sensitive adhesive tape 11 according to the second embodiment has the same function as the pressure-sensitive adhesive tape 6 according to the first embodiment.
 さらに、実施例2に係る粘着テープ11の効果について説明する。
 実施例2の粘着テープ11は、短手方向の長さが18mmであり、テープの幅がやや広いため短手方向の中央付近から外れた位置に指先や爪による力が加わる可能性がある。
 粘着テープ11では、切れ込み12が2列に亘って千鳥に配置されているため、安定的に切断できる。また、切れ込みの角度αの絶対値が小さい場合においても、切断が容易である。一方で、角度αの絶対値が小さいことから、切れ込み12が2列に配列されているにもかかわらず、高い引張強度を維持している。
 切れ込み12は、粘着テープ11の両側縁部や切断端の近傍に配置されないことから、各側縁部のみが破断されて粘着テープ11の巻体5や手にまとわり付いたり縦切れしたりすることがない。
 この他、実施例2に係る粘着テープ11は、実施例1に係る粘着テープ6と同様の効果を有する。
Furthermore, the effect of the adhesive tape 11 according to Example 2 will be described.
The adhesive tape 11 of Example 2 has a length in the short direction of 18 mm, and the width of the tape is slightly wide. Therefore, there is a possibility that a force from a fingertip or a nail is applied to a position deviating from the vicinity of the center in the short direction.
In the adhesive tape 11, since the notches 12 are arranged in a staggered manner over two rows, it can be cut stably. Further, even when the absolute value of the cut angle α is small, cutting is easy. On the other hand, since the absolute value of the angle α is small, high tensile strength is maintained even though the notches 12 are arranged in two rows.
Since the notch 12 is not disposed in the vicinity of both side edges or the cut end of the adhesive tape 11, only the side edges are broken, and the adhesive tape 11 is attached to the wound body 5 or the hand or vertically cut. There is nothing to do.
In addition, the adhesive tape 11 according to Example 2 has the same effect as the adhesive tape 6 according to Example 1.
 次に、実施例2に係る第1の変形例について、図11及び表4を用いて説明する。図11は、実施例2に係る第1の変形例の平面図である。
 図11に示すように、粘着テープ11aは、フィルム基材2の長手方向に沿って複数の切れ込み12aが設けられ、切れ込み配列13aを形成している。フィルム基材2は、OPPを材質とした短手方向の長さが24mmのフィルムである。切れ込み12aは、6mmの一定間隔bをおいて連続的に設けられている。さらに、切れ込み配列13aにおいては、フィルム基材2の短手方向の中央に一列、中央の列から垂直に互いに遠ざかる方向へ3mmずつ離して合計3列が設けられる。切れ込み配列13aは、左右の列同士の関係において並行配列を形成している。中央列の切れ込み12aは、長手方向においても左右の列の切れ込み12aの中間に位置している。よって、切れ込み配列13aは、中央列と左右の列との関係において、千鳥配列を形成している。
 また、切れ込み12aの長さは0.8mmで、切れ込み角度αは向かって左側の列が10度、中央の列が-10度、右側の列が-10度である。なお、図11において、粘着テープ11aの上端は押して切った時の切断端を示している。
Next, a first modification according to the second embodiment will be described with reference to FIG. FIG. 11 is a plan view of a first modification according to the second embodiment.
As shown in FIG. 11, the adhesive tape 11a is provided with a plurality of cuts 12a along the longitudinal direction of the film base 2 to form a cut array 13a. The film base 2 is a film having a length in the short direction of 24 mm made of OPP. The cuts 12a are continuously provided with a constant interval b of 6 mm. Further, in the cut array 13a, a total of three rows are provided, one row at the center in the short direction of the film substrate 2 and 3 mm apart in a direction away from each other vertically from the center row. The notch array 13a forms a parallel array in the relationship between the left and right columns. The notches 12a in the center row are located in the middle of the notches 12a in the left and right rows in the longitudinal direction. Therefore, the cut array 13a forms a staggered array in the relationship between the center column and the left and right columns.
Further, the length of the cut 12a is 0.8 mm, and the cut angle α is 10 degrees in the left column, −10 degrees in the center column, and −10 degrees in the right column. In addition, in FIG. 11, the upper end of the adhesive tape 11a has shown the cut end when it cuts by pushing.
  次に、粘着テープ11aの作用及び効果について説明する。
 粘着テープ11aは、短手方向の長さが粘着テープ11よりも広くなっているが、切れ込み12aが3列に亘って配列されていることから、短手方向の中央付近から押さえる位置が離れた場合であっても、その周囲に分布する切れ込み12aが多い。従って、切れ込み12aが拡張され、粘着テープ11aが切断されるという作用を有する。
 よって、粘着テープ11aは、幅が広いにもかかわらず安定的に切断できる。
 この他、粘着テープ11aは、実施例2の第1の変形例に係る粘着テープ11と同様の作用及び効果を有する。
Next, the operation and effect of the adhesive tape 11a will be described.
The length of the adhesive tape 11a in the short direction is wider than that of the adhesive tape 11, but since the cuts 12a are arranged in three rows, the position to be pressed from the vicinity of the center in the short direction is separated. Even in this case, there are many notches 12a distributed around the periphery. Therefore, the notch 12a is expanded and the adhesive tape 11a is cut.
Therefore, the adhesive tape 11a can be stably cut despite its wide width.
In addition, the adhesive tape 11a has the same operations and effects as the adhesive tape 11 according to the first modification of the second embodiment.
 次に、実施例2に係る第2の変形例について、図12及び表4を用いて説明する。
 図12は、実施例2に係る第2の変形例の平面図である。
 図12に示すように、粘着テープ11bは、複数の切れ込み12bが5列設けられ、切れ込み配列13bを形成している。切れ込み12bは、0.8mmの長さaを有し、5mmの一定間隔bをおいて連続的に設けられている。粘着テープ11bの短手方向の長さは50mmである。
 切れ込み配列13bにおいて、列は中央に1列、フィルム基材2の短手方向中央から互いに遠ざかる方向へ3mmと6mmずつ離して左右各2列の合計5列が設けられる。間隔dは0.55mm、間隔eは1.1mmである。よって、切れ込み配列13bでは、粘着テープ11bの短手方向に別の切れ込みが存在しないことになる。
 また、切れ込み角度αは、すべて-45度である。
Next, a second modification according to the second embodiment will be described with reference to FIG.
FIG. 12 is a plan view of a second modification example according to the second embodiment.
As shown in FIG. 12, the adhesive tape 11b is provided with five rows of a plurality of cuts 12b to form a cut array 13b. The notches 12b have a length a of 0.8 mm and are continuously provided with a constant interval b of 5 mm. The length of the adhesive tape 11b in the short direction is 50 mm.
In the notch arrangement 13b, a total of five rows are provided, one on the center and two on each of the left and right rows with a distance of 3 mm and 6 mm away from the center in the short direction of the film base 2. The interval d is 0.55 mm, and the interval e is 1.1 mm. Therefore, in the notch array 13b, another notch does not exist in the short direction of the adhesive tape 11b.
Further, the cut angles α are all −45 degrees.
 さらに、粘着テープ11bの作用について、図13を用いて説明する。図13は、実施例2に係る第2の変形例の利用例で、粘着テープ11bをダンボール箱本体14の蓋14aの封緘用として利用した例である。
 図13において、段ボール箱本体14と蓋14aは、粘着テープ11bにより互いに固定される。蓋14aを開封する場合は、段ボール箱本体14と蓋14aの隙間に沿って貼付された粘着テープ11bの表面を爪で押しながらなぞる。粘着テープ11bは、間隔dが0.55mmであるため,この隙間の周辺にはいずれかの切れ込み12bが存在することになる。この切れ込み12bに力が加わると拡張する。
 この拡張が段ボール箱本体14と蓋14aの隙間に沿って伸長し、その結果粘着テープ11bが短手方向に沿って切断される。反対側の粘着テープ11bも同様に切断できる。次に蓋14aと蓋14aの間の隙間を爪で押しながらなぞる。粘着テープ11bの切れ込み12bは5列いずれも間隔cが3mmで形成されているため、蓋14a同士の隙間の周辺にいずれかの切れ込み12bが存在する。この切れ込み12bに力が加わると、前述したと同様に粘着テープ11bが隙間に沿って長手方向に切断され、蓋14aを開けることができる。
 なお、粘着テープ11bは短手方向の幅が50mmと広いため、巻体5から必要量を切り取る場合は押して切ることができない可能性が考えられる。これは、切断時に長手方向に引っ張る力よりも押す力が勝った場合には、切れ込み12bの伸長が側縁部に向かわずに斜めに向かうためである。よって、このような場合においては、必要量の切り取りは従来通りの器具を用い切断する必要がある。
Furthermore, the effect | action of the adhesive tape 11b is demonstrated using FIG. FIG. 13 is an example of use of the second modification according to the second embodiment, in which the adhesive tape 11b is used for sealing the lid 14a of the cardboard box body 14.
In FIG. 13, the cardboard box body 14 and the lid 14a are fixed to each other by an adhesive tape 11b. When opening the lid 14a, the surface of the adhesive tape 11b attached along the gap between the cardboard box body 14 and the lid 14a is traced while pushing with a nail. Since the distance d of the adhesive tape 11b is 0.55 mm, any notch 12b exists around the gap. When a force is applied to this notch 12b, it expands.
This expansion extends along the gap between the cardboard box body 14 and the lid 14a, and as a result, the adhesive tape 11b is cut along the short direction. The adhesive tape 11b on the opposite side can be similarly cut. Next, the gap between the lid 14a and the lid 14a is traced while pushing with a nail. Since all the five rows of the cuts 12b of the adhesive tape 11b are formed with an interval c of 3 mm, any of the cuts 12b exists around the gap between the lids 14a. When a force is applied to the notch 12b, the adhesive tape 11b is cut in the longitudinal direction along the gap as described above, and the lid 14a can be opened.
In addition, since the width | variety of the transversal direction is as wide as 50 mm, when the adhesive tape 11b cuts a required amount from the wound body 5, it may be unable to push and cut. This is because when the pressing force is greater than the pulling force in the longitudinal direction at the time of cutting, the extension of the notch 12b is obliquely directed toward the side edge. Therefore, in such a case, it is necessary to cut the necessary amount using a conventional instrument.
 続いて、粘着テープ11bの効果について説明する。
 粘着テープ11bは、段ボール箱本体14の蓋14aなどの一時的な固定に用いた場合に道具を必要とせずに簡単に開封することができる。開封は爪でなぞるだけなのでカッターなどと異なり切る際に内部の物を傷つけることがない。また、押して切るテープの切断にはひとつの切れ込みしか必要がないので、切れ込みの数を減らすことができること及び、切断には隙間付近の切れ込みに局所的な力が必要であるため面的に加わる力では切断しにくいため、輸送中などに加わる意図しない力で切断しにくいことが利点である。
 粘着テープ11bの変形例として、切れ込みの場所がわかるように切れ込みとその周辺部に着色しても良い。また、蓋14a同士の隙間に確実に切れ込みが存在するように、切れ込み配列13bを粘着テープ11bの中央から短手方向左右に3mmほどの幅(すなわち、図2(b)の符号c)で緩やかに蛇行するように配列しても良い。
Then, the effect of the adhesive tape 11b is demonstrated.
The adhesive tape 11b can be easily opened without using a tool when used for temporarily fixing the lid 14a of the cardboard box body 14 or the like. Opening is only traced with a nail, so it doesn't damage the inside when cutting, unlike a cutter. In addition, since only one cut is necessary for cutting the tape to be pushed and cut, the number of cuts can be reduced, and the cutting requires a local force for the cut near the gap, so that the force applied on the surface In this case, it is difficult to cut with an unintended force applied during transportation.
As a modification of the adhesive tape 11b, the notch and its peripheral part may be colored so that the location of the notch is known. Further, in order to ensure that there is a notch in the gap between the lids 14a, the notch array 13b is loosened with a width of about 3 mm from the center of the adhesive tape 11b to the left and right in the short direction (that is, symbol c in FIG. 2B). It may be arranged so as to meander.
 なお、実施例2に係る粘着テープは、本実施例に示す構造に限定されるものではない。例えば、すべてのαが10度≦|α|≦60度でなくとも良く、今回の作用効果を発揮し得るものであれば、一部のαが60度<|α|≦90度であっても良い。
 また、切れ込みの間隔b,c,d,eは、表4に記載された以外の値でも良い。このとき、間隔bは、切れ込みの長さaの1倍以上で、少なくとも2mm以上であれば良い。また、間隔cは切れ込みの長さaの1.5倍以上とし、少なくとも3mm以上であれば良い。
 なお、これらの寸法の根拠については既に課題を解決するための手段の欄で述べたとおりである。
In addition, the adhesive tape which concerns on Example 2 is not limited to the structure shown in a present Example. For example, not all α need to satisfy 10 degrees ≦ | α | ≦ 60 degrees, and some α may satisfy 60 degrees <| α | ≦ 90 degrees as long as the present operation and effect can be exhibited. Also good.
Further, the notch intervals b, c, d, and e may be values other than those described in Table 4. At this time, the space | interval b should just be 1 time or more of the notch length a, and at least 2 mm or more. Further, the interval c is 1.5 times or more of the cut length a, and may be at least 3 mm.
The basis for these dimensions has already been described in the section of means for solving the problem.
 実施例3の粘着テープについて、図14乃至図18及び表5を用いて詳細に説明する(主に、請求項3に対応)。なお、図1乃至図13で示した構成要素については同一符号を付して、その説明を省略する。
 以下に、実施例3に係る粘着テープ15の構成について図14乃至図16と表5を参照しながら具体的に述べる。図14は、実施例3に係る粘着テープの平面図である。図15及び図16は、それぞれ図14の粘着テープに係る切れ込みの平面図である。なお、本例示により本願発明が制限されるものではない。

 図14に示すように、実施例3に係る粘着テープ15は、フィルム基材2の裏面に粘着層4を備え、ミシン目16が設けられている。
 粘着テープ15のフィルム基材2は、OPPを材質とした短手方向の長さが12mmのフィルムである。ミシン目16は長さaが1.4mmであり、5個の長さ0.2mmの微小な切れ込み16pが間隔0.1mmおきにミシン目状に連続して構成される(図15参照)。そして、ミシン目16はフィルム基材2の短手方向の中央に、粘着テープ15の長手方向に沿って3mmの均等間隔bをおいて一列に設けられ、ミシン目配列17を形成する。ミシン目16の角度αは30度である。この他の構成は、実施例1に係る粘着テープ6と同様である(図6参照)。なお、図14において、粘着テープ15の上端は押して切った時の切断端を示している。
As shown in FIG. 14, the pressure-sensitive adhesive tape 15 according to Example 3 includes the pressure-sensitive adhesive layer 4 on the back surface of the film base 2 and is provided with perforations 16.
The film substrate 2 of the adhesive tape 15 is a film having a length of 12 mm in the short direction made of OPP. The perforations 16 have a length a of 1.4 mm, and five minute cuts 16p each having a length of 0.2 mm are continuously formed in a perforation shape at intervals of 0.1 mm (see FIG. 15). The perforations 16 are provided in a line at the center of the film base 2 in the short direction along the longitudinal direction of the adhesive tape 15 with an equal interval b of 3 mm to form a perforation array 17. The angle α of the perforation 16 is 30 degrees. Other configurations are the same as those of the adhesive tape 6 according to the first embodiment (see FIG. 6). In addition, in FIG. 14, the upper end of the adhesive tape 15 has shown the cut end when it cuts by pushing.
 次に、実施例3に係る粘着テープ15の作用について説明する。
 粘着テープ16は、短手方向の中央付近を、上方より押すと、ミシン目16における0.1mm幅のフィルム基材2が切断され、長さ0.2mmの微小な切れ込み16p同士が連結する。
 ミシン目が連結された切れ込み16aを図16に示す。この切れ込み16aの長さaは1.4mmである。
 また、それぞれの微小な切れ込み16pは、ミシン目が連結した16aよりも粘着テープ15の長手方向における引っ張りに対し、より拡張し難い傾向にある。
 この他、切れ込み16aを備えた粘着テープ15の作用は実施例1の粘着テープ6と同様である。
Next, the effect | action of the adhesive tape 15 which concerns on Example 3 is demonstrated.
When the adhesive tape 16 is pressed near the center in the short direction from above, the 0.1 mm wide film substrate 2 at the perforation 16 is cut, and minute cuts 16p having a length of 0.2 mm are connected to each other.
FIG. 16 shows a cut 16a to which perforations are connected. The length a of the cut 16a is 1.4 mm.
In addition, each minute notch 16p tends to be more difficult to expand with respect to the pulling in the longitudinal direction of the adhesive tape 15 than 16a connected with perforations.
In addition, the action of the pressure-sensitive adhesive tape 15 provided with the notches 16a is the same as that of the pressure-sensitive adhesive tape 6 of the first embodiment.
 次に、実施例3に係る粘着テープ15の効果について説明する。
 図15と図16に示すように、ミシン目16を構成する微小な切れ込み16pが上から押す力で容易につながり、切れ込み16aになる。微小な切れ込み16pは、単独ではより拡張し難い傾向にあることから、粘着テープ15はより高い引張強度を有する。すなわち、ミシン目16は、実施例1に係る粘着テープ6の切れ込み7(図6参照)のようなミシン目状でない切れ込みよりも引張強度を強くできる。従って、ミシン目の角度αをより大きくしても十分な引張強度を維持することが可能である。
 この他、ミシン目16を備えた粘着テープ15の効果は実施例1の粘着テープ6と同様である。
Next, the effect of the adhesive tape 15 according to the third embodiment will be described.
As shown in FIGS. 15 and 16, the minute notches 16p constituting the perforation 16 are easily connected by a pressing force from above, and become the notches 16a. Since the small cut 16p tends to be difficult to expand by itself, the adhesive tape 15 has a higher tensile strength. That is, the perforation 16 can make the tensile strength stronger than a notch that is not perforated like the notch 7 (see FIG. 6) of the adhesive tape 6 according to the first embodiment. Therefore, it is possible to maintain a sufficient tensile strength even if the angle α of the perforation is increased.
In addition, the effect of the adhesive tape 15 provided with the perforation 16 is the same as that of the adhesive tape 6 of Example 1.
 次に、ミシン目16の第1の変形例に係る切れ込みについて、図17を用いて説明する。図17は、実施例3の第1の変形例の切れ込みを模式的に示した平面図であるが、必ずしもこの図の通りでなくて良い。
 図17に示すように、第1の変形例に係るミシン目集合16bは、微小な切れ込み16qが0.1mmの間隔を開けて平行に2列並んだものである。
 続いて、ミシン目集合16bの作用について説明する。ミシン目集合16bは上方からの力により微小な切れ込み16qが2列間でもつながるためミシン目集合16bはミシン目16よりも拡張され易い。しかし、ミシン目集合16bを構成する微小な切れ込み16qの長さは、16pと同じく短いため、引っ張る力に対しては拡張され難い。従って、引張強度へはあまり影響を与えない。
 なお、列数が増えるほど切断しやすくなるが、意図しない力や巻体5からはがす時に切れやすくなることを考慮して列数を決める必要がある。
Next, the notch according to the first modification of the perforation 16 will be described with reference to FIG. FIG. 17 is a plan view schematically showing the notch of the first modification of the third embodiment, but it is not necessarily as shown in this figure.
As shown in FIG. 17, the perforation set 16b according to the first modified example is one in which minute notches 16q are arranged in parallel in two rows with an interval of 0.1 mm.
Next, the operation of the perforation set 16b will be described. The perforation set 16b is easier to expand than the perforation 16 because the minute notches 16q are connected even between two rows by the force from above. However, since the length of the minute notches 16q constituting the perforation set 16b is as short as 16p, it is difficult to expand against the pulling force. Therefore, the tensile strength is not greatly affected.
The number of columns needs to be determined in consideration of the unintended force and the ease of disconnection from the wound body 5 as the number of columns increases.
 次に、ミシン目16の第2の変形例に係る切れ込みについて、図18を用いて説明する。図18は、実施例3の第2の変形例の切れ込みを模式的に示した平面図であるが、必ずしもこの図の通りでなくて良い。
 図18に示すように、第2の変形例に係るミシン目16cは、0.1mm間隔をおいて0.2mmの微小な不定形の切れ込み16rが連続したものである。ミシン目16cは、フィルム基材2の長手方向に対する角度を30度となるように直径0.3mmの鋭利な針を5本並べ、これをフィルム基材2へ刺入することで形成される。
 その他の構成は、ミシン目16と同様であり、作用についてもミシン目16と同様である。
 また、効果については、ミシン目16cは微小な不定形の切れ込み16rから形成されるため切れやすさにばらつきが生じるが、不定形の切れ込み16rを鋭利な針の他突起物で形成できるため加工の簡便さが大きな利点である。
 この他、ミシン目16cの効果は、ミシン目16と同様である。
Next, the notch according to the second modification of the perforation 16 will be described with reference to FIG. FIG. 18 is a plan view schematically showing a cut in the second modification of the third embodiment, but it does not necessarily have to be as shown in this figure.
As shown in FIG. 18, the perforation 16 c according to the second modification is a continuous series of minute irregular notches 16 r of 0.2 mm with an interval of 0.1 mm. The perforation 16c is formed by arranging five sharp needles having a diameter of 0.3 mm so that the angle with respect to the longitudinal direction of the film substrate 2 is 30 degrees and inserting the needles into the film substrate 2.
The other configuration is the same as that of the perforation 16, and the action is the same as that of the perforation 16.
As for the effect, the perforation 16c is formed from minute irregular shaped cuts 16r, so that the cutting ability varies, but the irregular shaped cuts 16r can be formed by other protrusions of sharp needles. Simpleness is a big advantage.
In addition, the effect of the perforation 16c is the same as that of the perforation 16.
 本発明の実施の形態に係る実施例4の押して切る粘着テープについて、図19乃至図28及び表5を用いて詳細に説明する(主に、請求項4に対応)。
 なお、図1乃至図18で示した構成要素については同一符号を付して、その説明を省略する。
 以下に、実施例4に係る粘着テープ18の構成について図19及び表5を参照しながら具体的に述べる。図19は、実施例4に係る粘着テープの平面図である。なお、本例示により本願発明が制限されるものではない。
The pressure-sensitive adhesive tape of Example 4 according to the embodiment of the present invention will be described in detail with reference to FIGS. 19 to 28 and Table 5 (mainly corresponding to claim 4).
The components shown in FIGS. 1 to 18 are denoted by the same reference numerals, and the description thereof is omitted.
Hereinafter, the configuration of the adhesive tape 18 according to Example 4 will be specifically described with reference to FIG. 19 and Table 5. FIG. 19 is a plan view of the adhesive tape according to the fourth embodiment. Note that the present invention is not limited by this illustration.
 図19に示すように、実施例4に係る粘着テープ18は、フィルム基材2に、複数の切れ込み19が設けられている。本実施例のフィルム基材2は、OPPを材質とした短手方向の長さが9mmのフィルムである。フィルム基材2には、粘着層4を備えない部分(図中斜線ハッチング部、以降の図において同じ)が設けられている。この部分は、粘着テープ18の短手方向中央から両側縁部に向かうおおよそ2/3の範囲内である。
 切れ込み19は長さaが2mmであり、フィルム基材2の短手方向の中央に、粘着テープ18の長手方向に沿って2mmの均等間隔をおいて一列に設けられ、切れ込み配列20を形成する。切れ込み19の角度αは60度である。なお、図19において、粘着テープ18の上端は押して切った時の切断端を示している。
As shown in FIG. 19, the adhesive tape 18 according to Example 4 is provided with a plurality of slits 19 in the film base 2. The film base 2 of the present embodiment is a film having a length of 9 mm in the short direction made of OPP. The film base 2 is provided with a portion not provided with the adhesive layer 4 (indicated by hatching in the figure, the same in the following figures). This portion is within a range of about 2/3 from the center in the short direction of the adhesive tape 18 toward both side edges.
The notches 19 have a length a of 2 mm, and are provided in a line at the center of the film base 2 in the short direction at an equal interval of 2 mm along the longitudinal direction of the adhesive tape 18 to form a notch array 20. . The angle α of the cut 19 is 60 degrees. In addition, in FIG. 19, the upper end of the adhesive tape 18 has shown the cut end when it cuts by pushing.
 次に、粘着テープ18の作用について、図20を用いて説明する。図20は、実施例4に係る粘着テープの利用例である。
 図20に示すように、粘着テープ18は、袋21の開口部を結束している。粘着テープ18の端部は、袋21に粘着させることなく、はがれないように粘着テープ18同士を粘着させている。但し、袋21に粘着されている粘着テープ18においても、当然ながら粘着層4を備えない斜線部分はこの袋21に粘着していない。
 具体的な開封方法は、粘着テープ18と袋21の結束部分を引っ張りながら粘着テープ18と袋21の境目付近の粘着テープ面を上から親指の爪で押すと、切れ込み19は粘着していないため拡張する。粘着テープ18の側縁部は、幾重にも折りたたまれた状態にある袋21の結束部分に粘着しているため、結束部分を広げるように扱うと粘着テープ18が長手方向に引っ張られるようになる。従って、切れ込み19は側縁部に向かって伸長し、粘着テープ18が切断される。
 なお、巻体5から粘着テープ18を必要量切り取る場合の作用は実施例1に係る粘着テープ6と同様である。
Next, the effect | action of the adhesive tape 18 is demonstrated using FIG. FIG. 20 is a usage example of the adhesive tape according to the fourth embodiment.
As shown in FIG. 20, the adhesive tape 18 binds the opening of the bag 21. The end portions of the adhesive tape 18 adhere the adhesive tapes 18 so as not to peel off without adhering to the bag 21. However, even in the adhesive tape 18 adhered to the bag 21, the hatched portion not provided with the adhesive layer 4 is not adhered to the bag 21.
As a specific opening method, when the adhesive tape surface near the boundary between the adhesive tape 18 and the bag 21 is pushed with a nail of the thumb from above while pulling the bound portion of the adhesive tape 18 and the bag 21, the cut 19 is not adhered. Expand. Since the side edge portion of the adhesive tape 18 adheres to the binding portion of the bag 21 that is folded several times, the adhesive tape 18 is pulled in the longitudinal direction when the binding portion is handled so as to be widened. . Accordingly, the cut 19 extends toward the side edge, and the adhesive tape 18 is cut.
The operation when the necessary amount of the adhesive tape 18 is cut from the wound body 5 is the same as that of the adhesive tape 6 according to the first embodiment.
 次に、粘着テープ18の効果について、説明する。
 粘着テープ18は、これを結束用テープに用いた場合、簡単に切断することができる。従来の結束用の粘着テープは、手での切断が不可能に近く、また粘着力が強いためこれをはがして取ることもほぼ不可能であったが、粘着テープ18はこのような課題を十分に解決するものである。また、結束時に粘着テープ18には長手方向に強い力が加わるが、切れ込み19の長さaと切れ込みの角度αを適宜設定することにより、引張強度を調整できる。よって、結束中に不用意に切断され難く、結束を失敗しにくい。
 この他、実施例1に係る粘着テープ6と同様の効果を有する。
Next, the effect of the adhesive tape 18 will be described.
The adhesive tape 18 can be easily cut when it is used as a binding tape. Conventional adhesive tape for bundling is almost impossible to cut by hand, and because of its strong adhesive force, it was almost impossible to peel it off. It will be solved. Further, a strong force is applied to the adhesive tape 18 in the longitudinal direction at the time of binding, but the tensile strength can be adjusted by appropriately setting the length a of the cut 19 and the cut angle α. Therefore, it is difficult to cut carelessly during binding, and binding is unlikely to fail.
In addition, it has the same effect as the adhesive tape 6 according to the first embodiment.
 次に、実施例4に係る第1の変形例及び第2の変形例について、図21及び図22を用いて説明する。図21は、実施例4に係る第1の変形例の使用状態図であり、図22は、実施例4に係る第2の変形例の使用状態図である。
 図21に示すように、本実施例の第1の変形例に係る粘着テープ18aは、その長手方向に所望の長さを有する粘着層4を備えない部分を繰り返し設けるものである。粘着層4を備えない部分の長さは用途によって定められるとよい。また、本変形例では短手方向全体に粘着層4を備えない部分を形成させているが、実施例4のように短手方向の一部分において粘着層4を備えない部分のものを用いてもよい。本変形例においてもフィルム基材2に、複数の切れ込み19aが設けられている。本実施例のフィルム基材2は、OPPを材質とした短手方向の長さが18mmのフィルムである。切れ込み19aは長さaが0.8mmであり、フィルム基材2の短手方向の中央に、粘着テープ18aの長手方向に沿って3mmの均等間隔をおいて一列に設けられ、切れ込み配列20aを形成する。切れ込み19aの角度αは30度である。
 本変形例では、粘着層4を備えない部分は、長手方向に沿って長さ6cmの範囲内としている。なお、透明なフィルム基材2と粘着層4を着色することで粘着層4の有無を明確にすることができる。
Next, a first modification and a second modification according to the fourth embodiment will be described with reference to FIGS. 21 and 22. FIG. 21 is a use state diagram of the first modification example according to the fourth embodiment, and FIG. 22 is a use condition diagram of the second modification example according to the fourth embodiment.
As shown in FIG. 21, the pressure-sensitive adhesive tape 18a according to the first modification of the present embodiment repeatedly provides a portion not including the pressure-sensitive adhesive layer 4 having a desired length in the longitudinal direction. The length of the portion not provided with the adhesive layer 4 may be determined depending on the application. Further, in this modification, a portion not provided with the adhesive layer 4 is formed in the entire short direction, but a portion having no adhesive layer 4 in a part in the short direction as in Example 4 may be used. Good. Also in this modification, the film base 2 is provided with a plurality of cuts 19a. The film base 2 of the present embodiment is a film having a length in the short direction of 18 mm made of OPP. The cuts 19a have a length a of 0.8 mm, and are provided in a line at the center in the short direction of the film base 2 at a uniform interval of 3 mm along the longitudinal direction of the adhesive tape 18a. Form. The angle α of the cut 19a is 30 degrees.
In this modification, the portion not provided with the adhesive layer 4 is in the range of 6 cm in length along the longitudinal direction. In addition, the presence or absence of the adhesion layer 4 can be clarified by coloring the transparent film substrate 2 and the adhesion layer 4.
 そして、図22に示すように、本実施例の第2の変形例に係る粘着テープ18bは、切れ込み19bのない一定長さ部分を備える。この切れ込み19bのない部分が、粘着層4を備えている。この他の構成は、粘着テープ18aと同様である。なお、粘着層4を備えない部分については、変形例1と同様に短手方向全体に形成されているが、短手方向の一部分において粘着層4を備えるようにしてもよい。 And as shown in FIG. 22, the adhesive tape 18b which concerns on the 2nd modification of a present Example is provided with the fixed length part without the notch 19b. The portion without the notch 19b includes the adhesive layer 4. Other configurations are the same as those of the adhesive tape 18a. In addition, about the part which is not provided with the adhesion layer 4, although it forms in the whole short direction similarly to the modification 1, you may make it provide the adhesion layer 4 in a part of short direction.
 次に、粘着テープ18a及び粘着テープ18bの作用について説明する。
 図21に示すように、粘着テープ18aにおいては、粘着層4を持たない部分が結束物21aと結束物21aの間に位置している。このような場合は、この部分の切れ込み19aは結束物21aに粘着していないため、テープ中央を指先か爪で押すことにより近くの切れ込み19aが拡張して粘着テープ18aの側端部に伸長し、粘着テープ18aは切断される。結束物21aが柔軟に変化する場合は、テープ中央を押しても、結束物21aが変形するためにテープを引っ張る力が作用しないので切ることができない。この場合は、人差し指と中指を粘着テープ18aと結束物21aの間に入れ、粘着テープ18aを手前に引きながら親指の先か爪で粘着テープ18aを押すと切断することができる。
 続いて、図22に示すように、粘着テープ18bにおいては、結束物21aには粘着層4を持たない部分が位置している。例えば、結束物21aが、柔軟性を備えていない場合では、切れ込み19bを上から押しても結束物21aが凹まずに支持体となって切れ込み19bが拡張しないため、粘着テープ18bは切断されない。しかし、結束物21aがウィンナーの袋のように食品と共に空気の入ったパックのように形が容易に変化するものでは、粘着テープ18bと結束物21aの間に人指し指と中指を挿入することが可能である。そのようにして親指の指先でテープ中央を押すと切れ込み19bが拡張し、粘着テープ18bが切断される。その後粘着層4を持たない切断端をつかみ剥ぎとることで結束を解除できる。
Next, the operation of the adhesive tape 18a and the adhesive tape 18b will be described.
As shown in FIG. 21, in the adhesive tape 18a, the part which does not have the adhesion layer 4 is located between the binding material 21a and the binding material 21a. In such a case, the cut 19a in this portion is not adhered to the bundle 21a, so by pressing the center of the tape with a fingertip or nail, the nearby cut 19a expands and extends to the side end of the adhesive tape 18a. The adhesive tape 18a is cut. When the bound material 21a changes flexibly, even if the center of the tape is pushed, the bound material 21a is deformed, and the force for pulling the tape does not act, so that it cannot be cut. In this case, the index finger and the middle finger can be cut by placing the index finger and the middle finger between the adhesive tape 18a and the bundle 21a and pressing the adhesive tape 18a with the tip of the thumb or the nail while pulling the adhesive tape 18a forward.
Then, as shown in FIG. 22, in the adhesive tape 18b, the part which does not have the adhesive layer 4 is located in the binding material 21a. For example, in the case where the bundle 21a does not have flexibility, even if the cut 19b is pushed from above, the bundle 21a becomes a support without being recessed and the cut 19b does not expand, so the adhesive tape 18b is not cut. However, in the case where the bundle 21a is easily changed in shape like a pack containing air together with food such as a wiener bag, it is possible to insert an index finger and a middle finger between the adhesive tape 18b and the bundle 21a. It is. In this way, when the center of the tape is pushed with the tip of the thumb, the cut 19b expands and the adhesive tape 18b is cut. Thereafter, the binding can be released by grasping and peeling off the cut end without the adhesive layer 4.
 さらに、粘着テープ18a及び粘着テープ18bの効果について説明する。
 粘着テープ18a及び粘着テープ18bは、いずれもウィンナーの袋のように食品と共に空気の入った柔軟性を備えたパック等の結束に適する。この場合は、粘着層4を備えない部分の位置に関わらず、器具を用いずに指で容易に切断することができる。特に、図22に示されるように、粘着テープ18bの粘着層4を備えない部分が結束物21aに密着する場合は、切れ込み19bは粘着層4を持たずに空気の入ったパックに押されているため、輸送時等に粘着テープ18bに圧力がかかっても、パック自身が一定量変形するだけで粘着テープ18bの切れ込み19bに局所的な力が加わる可能性が小さく、切れ込み19bの隙間が広がる可能性も低い。このため、輸送中などに強い力が作用しても切れることが少ないのである。
 粘着層4にも切れ込みのある粘着テープ18aは、巻体5から必要な長さを切り取る場合にも押すことのみで切断できる。しかし、粘着テープ18bの切断は器具が必要である。
Further, effects of the adhesive tape 18a and the adhesive tape 18b will be described.
Both of the adhesive tape 18a and the adhesive tape 18b are suitable for bundling of a pack or the like having flexibility that contains air together with food like a Wiener bag. In this case, regardless of the position of the portion not provided with the adhesive layer 4, it can be easily cut with a finger without using an instrument. In particular, as shown in FIG. 22, when the portion of the adhesive tape 18 b that does not have the adhesive layer 4 is in close contact with the bundle 21 a, the cut 19 b does not have the adhesive layer 4 and is pushed by the pack containing air. Therefore, even when pressure is applied to the adhesive tape 18b during transportation or the like, there is little possibility that a local force is applied to the cut 19b of the adhesive tape 18b simply by deforming the pack itself by a certain amount, and the gap of the cut 19b is widened. The possibility is low. For this reason, even if a strong force is applied during transportation or the like, it is unlikely to break.
The pressure-sensitive adhesive tape 18 a having a cut also in the pressure-sensitive adhesive layer 4 can be cut only by pressing even when a necessary length is cut from the wound body 5. However, a tool is required for cutting the adhesive tape 18b.
 次に、実施例4に係る第3の変形例及び第4の変形例について、図23及び図24を用いて説明する。図23は、実施例4に係る第3の変形例の平面図であり、図24は、実施例4に係る第4の変形例の使用状態図である。
 図23に示すように、本実施例の第3の変形例に係る粘着テープ18cは、フィルム基材2に、複数のミシン目19cが設けられている。その他の構成は表5に示した。この粘着層4を備えない部分は、粘着テープ18cの短手方向中央から一方の側縁部までを占める部分である。
 さらに、図24に示すように、本実施例の第4の変形例に係る粘着テープ18dは、粘着テープ18cのミシン目19cのうち、粘着層4が備えられた側の切れ込みが省略されたものであって、ミシン目19dのみを備えている。その他の構成は、粘着テープ18cと同様である。図24においては、粘着テープ18dを用いて結束物21aを結束している。
Next, a third modification and a fourth modification according to the fourth embodiment will be described with reference to FIGS. FIG. 23 is a plan view of a third modification example according to the fourth embodiment, and FIG. 24 is a use state diagram of the fourth modification example according to the fourth embodiment.
As shown in FIG. 23, the adhesive tape 18c according to the third modification of the present embodiment is provided with a plurality of perforations 19c on the film base 2. Other configurations are shown in Table 5. The part not provided with the adhesive layer 4 is a part that occupies from the center in the short direction of the adhesive tape 18c to one side edge.
Furthermore, as shown in FIG. 24, the adhesive tape 18d according to the fourth modification of the present embodiment is one in which the notch on the side where the adhesive layer 4 is provided is omitted from the perforation 19c of the adhesive tape 18c. However, only the perforation 19d is provided. Other configurations are the same as those of the adhesive tape 18c. In FIG. 24, the bundle 21a is bundled using the adhesive tape 18d.
 次に、粘着テープ18c及び粘着テープ18dの作用について説明する。
 粘着テープ18cの作用は、一時的な固定に用いた場合では、粘着テープ18cの粘着層4を備えない部分に設けられたミシン目19cを押さえると、ミシン目がつながり切れ込みとなり、切れ込みは粘着層4を備えない側縁部まで容易に達する。さらに、粘着層4を持たない部分を掴んで粘着している部分を剥がすと粘着テープ18cを切断することができる。
 粘着テープ18dは、長手方向のどの部分でも粘着層4を備えない部分を持つので、粘着テープ18dと結束物21aの間に隙間があれば、ミシン目19dを上から押すことができるので任意の部分で切断できる。具体的には、粘着テープ18dの粘着層4を持たない部分に人指し指と中指を入れミシン目19dの存在する付近を上方から親指の先で押すと近くのミシン目19dがつながり切れ込みとなり、切れ込みは拡張し、粘着テープ18dの粘着層4を持たない部分が切断される。結束物21aに粘着している粘着テープ18dを切断するためには、粘着テープ18cと同様に粘着層4のない部分を掴んで剥がすと切断することができる。
Next, the operation of the adhesive tape 18c and the adhesive tape 18d will be described.
When the adhesive tape 18c is used for temporary fixing, when the perforation 19c provided in the portion of the adhesive tape 18c that does not include the adhesive layer 4 is pressed, the perforation is connected and cut, and the cut becomes the adhesive layer. Easily reach side edges without 4. Furthermore, the adhesive tape 18c can be cut by grasping the part that does not have the adhesive layer 4 and removing the adhesive part.
Since the adhesive tape 18d has a portion that does not include the adhesive layer 4 in any part in the longitudinal direction, if there is a gap between the adhesive tape 18d and the bundle 21a, the perforation 19d can be pushed from above so that any Can be cut at a part. Specifically, when the index finger and the middle finger are put into the portion of the adhesive tape 18d that does not have the adhesive layer 4 and the vicinity of the perforation 19d is pressed with the tip of the thumb from above, the nearby perforation 19d is connected and cut. It expands and the part which does not have the adhesion layer 4 of the adhesive tape 18d is cut | disconnected. In order to cut | disconnect the adhesive tape 18d adhering to the binding material 21a, it can cut | disconnect, if the part which does not have the adhesion layer 4 is grasped and peeled similarly to the adhesive tape 18c.
 次に、粘着テープ18c及び粘着テープ18dの効果について説明する。
粘着テープ18c及び粘着テープ18dは、切れ込みに替えてミシン目19c,19dを用いるので、切れ込みよりも引張強度に優れる。 
 粘着テープ18cにおける粘着層4を備える部分のミシン目19cは、一度結束物等に粘着させると、粘着テープ18cの切断には利用できないが、巻体5から必要な長さを切り取るときには、結束物等に粘着されていないため押すことにより切断できる。しかし、粘着テープ18dはミシン目19dが片側のみなので巻体5から必要な長さを切り取るときには、器具を用いて行う方が良い。
 粘着テープ18c及び粘着テープ18dは、形状が変化しない結束物でも、結束物間に位置する部分において容易に切断できる点が優れる。また、長手方向のどの部分でも粘着層4を備えない部分を持つので、粘着テープ18dと結束物21aの間に指などで隙間を作ることができれば、ミシン目19dを押すことができるので、任意の部分で切断できる。
 さらに、粘着層4を持たない部分が粘着テープ18c,18dの長手方向に平行であるため、粘着層4の塗布が簡単である。
Next, effects of the adhesive tape 18c and the adhesive tape 18d will be described.
Since the adhesive tape 18c and the adhesive tape 18d use the perforations 19c and 19d instead of the slits, they are superior in tensile strength to the slits.
The perforation 19c of the part having the adhesive layer 4 in the adhesive tape 18c cannot be used for cutting the adhesive tape 18c once it is adhered to a bundle or the like, but when the necessary length is cut from the wound body 5, It can be cut by pressing because it is not adhered to the surface. However, since the adhesive tape 18d has the perforation 19d only on one side, it is better to use a tool when cutting the required length from the wound body 5.
The adhesive tape 18c and the adhesive tape 18d are excellent in that they can be easily cut at a portion located between the bundles even if the bundles do not change in shape. Further, since any portion in the longitudinal direction does not include the adhesive layer 4, if a gap can be formed between the adhesive tape 18d and the bundle 21a with a finger or the like, the perforation 19d can be pushed, so any Can be cut at the part.
Furthermore, since the part which does not have the adhesion layer 4 is parallel to the longitudinal direction of the adhesion tapes 18c and 18d, the application of the adhesion layer 4 is easy.
 次に、実施例4に係る第5の変形例について、図25を用いて説明する。
 図25は、実施例4に係る第5の変形例の平面図である。 
 図25に示すように、本実施例の第5の変形例に係る粘着テープ18eは、フィルム基材2に、複数の切れ込み19eが設けられている。
 本実施例のフィルム基材2は、OPPを材質とした短手方向の長さが18mmのフィルムである。切れ込み19eは長さaが0.8mmであり、フィルム基材2の短手方向の中央に、粘着テープ18eの長手方向に沿って5mmの均等間隔bをおいて2列に設けられる。各列はフィルム基材2の短手方向中央から互いに遠ざかる方向へ3mmずつ離隔しており、切れ込み配列20eを形成する。切れ込み19eの角度αは、向かって左側の列が30度、右側の列が-30度である。
また、粘着層4を持たない部分は粘着テープ18eの長手方向に沿った長さ1cmの範囲内である。なお、図25において、粘着テープ18eの上端は押して切った時の切断端を示している。
Next, a fifth modification of the fourth embodiment will be described with reference to FIG.
FIG. 25 is a plan view of a fifth modification example according to the fourth embodiment.
As shown in FIG. 25, the adhesive tape 18e which concerns on the 5th modification of a present Example is provided with the some notch 19e in the film base material 2. As shown in FIG.
The film base 2 of the present embodiment is a film having a length in the short direction of 18 mm made of OPP. The notches 19e have a length a of 0.8 mm, and are provided in two rows at the center in the short direction of the film substrate 2 with an equal interval b of 5 mm along the longitudinal direction of the adhesive tape 18e. Each row is separated by 3 mm in the direction away from the center in the short direction of the film base 2 to form a cut array 20e. The angle α of the cut 19e is 30 degrees on the left side and -30 degrees on the right side.
Moreover, the part which does not have the adhesion layer 4 exists in the range of length 1cm along the longitudinal direction of the adhesive tape 18e. In addition, in FIG. 25, the upper end of the adhesive tape 18e has shown the cut end when it cuts by pushing.
 次に、粘着テープ18eの作用及び効果について、図26を用いて説明する。
 図26は、実施例4に係る第5の変形例の使用状態図である。  
 図26に示すように、粘着テープ18eは、箱本体22と蓋22aの固定に用いられており、蓋22aの開封部分には粘着層4を持たない部分を位置させている。蓋22aを開封する場合は、粘着テープ18eの上から箱本体22と蓋22aの間を爪で押すと局所的な力により、蓋22aが箱本体22の内部に押し込まれ、粘着テープ18eと蓋22aの間に空間が生じる。押し込まれることにより粘着テープ18eに力が加わり、近くの切れ込み19eが拡張して粘着テープ18eの側縁部に伸長し、粘着テープ18eが切断される。
 さらに、粘着テープ18eは、押すことのみにより切断されるため、蓋22aを極めて容易に開封可能である。局所的でない力が蓋22a全体に加わった場合は、蓋22aはやや内側に凹むが、その程度では切れ込み19eは拡張しないため、意図しない力によって蓋22aは開封されにくい。
Next, the operation and effect of the adhesive tape 18e will be described with reference to FIG.
FIG. 26 is a diagram illustrating a usage state of the fifth modification example according to the fourth embodiment.
As shown in FIG. 26, the adhesive tape 18e is used for fixing the box body 22 and the lid 22a, and a portion that does not have the adhesive layer 4 is located in the opening portion of the lid 22a. When opening the lid 22a, when the nail is pressed between the box body 22 and the lid 22a from above the adhesive tape 18e, the lid 22a is pushed into the box body 22 by a local force, and the adhesive tape 18e and the lid A space is created between 22a. By being pushed in, a force is applied to the adhesive tape 18e, the nearby cut 19e expands and extends to the side edge of the adhesive tape 18e, and the adhesive tape 18e is cut.
Furthermore, since the adhesive tape 18e is cut only by pressing, the lid 22a can be opened very easily. When a non-local force is applied to the entire lid 22a, the lid 22a is slightly recessed inside, but the notch 19e does not expand to that extent, and therefore the lid 22a is not easily opened by an unintended force.
 次に、実施例4に係る第6の変形例について、図27を用いて説明する。
 図27は、実施例4に係る第6の変形例の平面図である。 
 図27に示すように、本実施例の第6の変形例に係る粘着テープ18fは、フィルム基材2に、複数の切れ込み19fが設けられている。
 本実施例の粘着テープ18fは、粘着層4を持たない部分を備えている点を除き、実施例2の第1の変形例に係る粘着テープ11a(図11参照)と同じ構成である。
 粘着層4を持たない部分は、長手方向に沿って長さ2cmであって、短手方向において片側から5/6の範囲内である。
Next, a sixth modification of the fourth embodiment will be described with reference to FIG.
FIG. 27 is a plan view of a sixth modification example according to the fourth embodiment.
As shown in FIG. 27, the adhesive tape 18f according to the sixth modification of the present embodiment is provided with a plurality of cuts 19f in the film base 2.
The pressure-sensitive adhesive tape 18f of the present example has the same configuration as the pressure-sensitive adhesive tape 11a (see FIG. 11) according to the first modified example of Example 2 except that a portion not having the pressure-sensitive adhesive layer 4 is provided.
The portion not having the adhesive layer 4 is 2 cm in length along the longitudinal direction, and is within a range of 5/6 from one side in the lateral direction.
 次に、粘着テープ18fの作用及び効果について、説明する。
 粘着テープ18fは、向かって左側の斜線以外の部分は粘着層4を備えるため、結束物に貼付すると上方から押すだけでは切れ込み19fは拡張せず、粘着テープ18fは切断されない。しかし、例えば蓋22a(図26参照)を固定する目的で粘着テープ18fを利用している場合は、蓋22aを強く押さえると蓋22aが箱22に押し込まれて粘着層4が蓋22aから剥がれ、粘着テープ18fは粘着テープ18eと同様に切断される。
 粘着テープ18fは、粘着テープ18eと同様に蓋22a等の一時的固定に用いられるが、粘着テープ18eと異なり一部に粘着層4を持つため、粘着テープ18eよりも強い力で蓋22aと箱本体22の間を爪で押す必要がある。しかし、逆に粘着テープ18eより強く固定されることから、輸送中に粘着テープ18fが切断される可能性は少なくなる。なお、粘着層4のない部分の面積は、実際の利用に適するよう適宜変更すれば良く、図27以外であっても良い。
 この他、実施例2の第2の変形例に係る粘着テープ11bと同様の作用及び効果を有する。
Next, the operation and effect of the adhesive tape 18f will be described.
Since the adhesive tape 18f is provided with the adhesive layer 4 at portions other than the diagonal line on the left side of the adhesive tape 18f, if the adhesive tape 18f is attached to a bundle, the cut 19f is not expanded only by pressing from above, and the adhesive tape 18f is not cut. However, for example, when the adhesive tape 18f is used for the purpose of fixing the lid 22a (see FIG. 26), if the lid 22a is pressed firmly, the lid 22a is pushed into the box 22 and the adhesive layer 4 is peeled off from the lid 22a. The adhesive tape 18f is cut in the same manner as the adhesive tape 18e.
The adhesive tape 18f is used for temporary fixing of the lid 22a and the like similarly to the adhesive tape 18e. However, since the adhesive layer 4 is partly provided unlike the adhesive tape 18e, the lid 22a and the box are stronger than the adhesive tape 18e. It is necessary to push between the main bodies 22 with a nail. However, since the adhesive tape 18e is fixed stronger than the adhesive tape 18e, the possibility that the adhesive tape 18f is cut during transportation is reduced. In addition, what is necessary is just to change suitably the area of the part without the adhesive layer 4 so that it may be suitable for actual utilization, and other than FIG.
In addition, it has the same operation and effect as the adhesive tape 11b according to the second modification of the second embodiment.
 次に、実施例4に係る第7の変形例について、図28を用いて説明する。
 図28は、実施例4に係る第7の変形例の平面図である。
 図28に示すように、本実施例の第7の変形例に係る粘着テープ18gは、フィルム基材2に、複数の切れ込み19gが設けられている。
 本実施例の粘着テープ18gは、粘着層4を持たない部分を備えている点を除き、実施例1の第2の変形例に係る粘着テープ6b(図9参照)と同じ構成である。
 粘着層4を持たない部分は、切れ込み19gがある部分を中心に粘着テープ18gの長手方向に沿って長さ4cmの範囲内である。なお、図28において、粘着テープ18gの上端は押して切った時の切断端を示している。
Next, a seventh modification of the fourth embodiment is described with reference to FIG.
FIG. 28 is a plan view of a seventh modification example according to the fourth embodiment.
As shown in FIG. 28, the adhesive tape 18g according to the seventh modification of the present embodiment is provided with a plurality of cuts 19g in the film base 2.
The pressure-sensitive adhesive tape 18g of the present example has the same configuration as the pressure-sensitive adhesive tape 6b (see FIG. 9) according to the second modification example of Example 1 except that a portion not having the pressure-sensitive adhesive layer 4 is provided.
The portion not having the adhesive layer 4 is within a range of 4 cm in length along the longitudinal direction of the adhesive tape 18g, centering on the portion having the cut 19g. In FIG. 28, the upper end of the adhesive tape 18g shows the cut end when it is cut by pressing.
 次に、粘着テープ18gの作用及び効果について説明する。
 粘着テープ18gは、巻体5から必要長さを切り取る時に、切れ込み位置マーク10が示す部分を指先か爪で押すことにより切れ込み19gが拡張し、その結果切断される。
 粘着テープ18gは、予め三角形で示す切れ込み位置マーク10でしか切れないので一定の使用長となり無駄がない。切断された端末に粘着層4を持たないので両端末を持って対象物に貼りつけても指に粘着しないので貼り付けやすい。また、指紋が残らないので美観を維持できる。さらに、粘着テープ18gを剥がす時にこの部分を掴むことで剥がしやすい。よって、粘着テープ18gは輸送中等の一時的な工業製品の部品の固定に利用できる。
 この他、実施例1の第2の変形例に係る粘着テープ6bと同様の作用及び効果を有する。
Next, the operation and effect of the adhesive tape 18g will be described.
When the adhesive tape 18g cuts the required length from the wound body 5, the cut 19g is expanded by pressing the portion indicated by the cut position mark 10 with a fingertip or a nail, and is cut as a result.
Since the adhesive tape 18g can be cut only at the cut position mark 10 previously indicated by a triangle, the length of the adhesive tape is constant and there is no waste. Since the cut-off terminal does not have the adhesive layer 4, even if it is attached to an object while holding both terminals, it does not stick to the finger and is easy to apply. Also, since no fingerprints remain, the beauty can be maintained. Further, when the adhesive tape 18g is peeled off, it is easy to peel off by grasping this portion. Therefore, the adhesive tape 18g can be used for temporarily fixing parts of industrial products such as during transportation.
In addition, it has the same operation and effect as the adhesive tape 6b according to the second modification of the first embodiment.
 請求項1乃至請求項4に記載された発明は、粘着テープのフィルム基材を指先や爪で押さえるのみで容易に切断できると同時に、粘着テープの長手方向の引張強度を維持しているので包装や、紙などの貼り付けなどに用いる物品の梱包用粘着テープ並びに、容器と蓋の固定、食品パックの束の結束などに用いる結束用粘着テープとして適用可能である。  The invention described in claims 1 to 4 can be easily cut by simply pressing the film base of the adhesive tape with a fingertip or a nail, and at the same time maintains the tensile strength in the longitudinal direction of the adhesive tape. It can also be applied as an adhesive tape for packing articles used for pasting paper and the like, and as a binding adhesive tape used for fixing containers and lids, binding bundles of food packs, and the like.
