Description

本発明は、粘着面が表側(外側)を向くように巻回された清掃用の粘着テープロールに関し、さらに詳しく言えば、手切れ性のよい切れ目を有する粘着テープロールに関する。   The present invention relates to an adhesive tape roll for cleaning wound so that an adhesive surface faces the front side (outside), and more specifically, relates to an adhesive tape roll having a cut with good hand cutting properties.

カーペットなどの床や衣服などに付着したホコリなどを除去する清掃用具の1つとして、粘着テープクリーナーがある。この粘着テープクリーナーは、粘着面が表側(外側)を向くように巻回された粘着テープロールを清掃面上で粘着面を転動することにより、粘着面でホコリを捕捉する。 An adhesive tape cleaner is one of the cleaning tools for removing dust adhering to floors such as carpets and clothes. The adhesive tape cleaner, adhesive surface by rolling to Rukoto the adhesive surface on the cleaning surface an adhesive tape roll wound so as to face the front side (outside), to capture the dust in the adhesive surface.

粘着テープには、外層の汚れた粘着テープを切り離すため、切断用の切れ目がほぼ1周長ごとに設けられている。例えば特許文献1に示すように、通常、切れ目は、粘着テープを貫通する切断部と、隣接する切断部の間に残された未切断部とを幅方向に沿って交互に配置する、いわゆるミシン目構造を備えている。 The adhesive tape for separating the adhesive tape dirty outermost layer, cut for cutting is provided approximately every one cycle length. For example, as shown in Patent Document 1, the cut is usually a so-called sewing machine in which cut portions that penetrate the adhesive tape and uncut portions left between adjacent cut portions are alternately arranged along the width direction. It has an eye structure.

これによれば、使用済みの外層の粘着テープを切れ目に沿って切り離すことにより、粘着テープの未使用面が外層に表れる。通常、この切れ目は、粘着テープをロール状に巻き取ったのち、多数の刺入刃を備えたカッターを粘着テープロールの半径方向の外側から内側に向かって差し込むことにより形成される。 According to this, by separating along the break of the adhesive tape of the spent outermost unused surface of the adhesive tape appears in the outermost layer. Normally, the cut is formed by winding the adhesive tape into a roll and then inserting a cutter having a large number of insertion blades from the outside in the radial direction of the adhesive tape roll to the inside.

しかしながら、粘着テープロールにカッターを刺入してゆくと、カッターの厚みによって粘着テープが強制的に押し広げられ、粘着テープロールがカッターの刺入部に沿って半分に割れてしまうおそれがある。   However, when the cutter is inserted into the adhesive tape roll, the adhesive tape is forcibly expanded by the thickness of the cutter, and the adhesive tape roll may be split in half along the insertion portion of the cutter.

このテープ割れを防止する手段としては、切れ目に含まれる各切断部の長さを短くすればよいが、切断部の長さを短くすると、未切断部が増える分、粘着テープが切り離しにくくなる。したがって、切れ目の設計には慎重を要する。   As a means for preventing the tape breakage, the length of each cut portion included in the cut may be shortened. However, when the length of the cut portion is shortened, the uncut portion is increased, so that the adhesive tape is difficult to separate. Therefore, care must be taken when designing the cut.

The invention according to claim 1 is formed by winding an adhesive tape having an adhesive material layer formed over substantially the entire surface of one side of the substrate so that the adhesive surface faces the front side. In the pressure-sensitive adhesive tape roll in which cuts for cutting each length are provided along the width direction, the cuts are uncut portions left between the cut portions penetrating the pressure-sensitive adhesive tape and the adjacent cut portions. Is a perforation structure alternately arranged along the width direction of the adhesive tape, and the length of the cut portion is L1 when the length of the cut portion is L1 and the length of the uncut portion is L2. The ratio between the length L1 and the length L2 of the uncut portion is L1: L2 = 1: 0 . The pressure-sensitive adhesive layer is made of a strong pressure-sensitive adhesive material having a tensile strength per unit area of 10 to 100 N / cm 2 .

請求項2に記載の発明は、上記請求項1において、上記粘着材層の層厚さTは、T=0.01〜0.05mmであることを特徴としている。   A second aspect of the present invention is characterized in that, in the first aspect, the thickness T of the adhesive layer is T = 0.01 to 0.05 mm.

請求項3に記載の発明は、上記請求項1または2において、上記強粘着材は、スチレン・イソプレン系粘着材および/またはスチレン・ブタジエン系粘着材を主成分として構成されていることを特徴としている。   A third aspect of the present invention is characterized in that, in the first or second aspect, the strong adhesive material is mainly composed of a styrene / isoprene adhesive material and / or a styrene / butadiene adhesive material. Yes.

これによれば、所定の強粘着材を用いることにより、強粘着材が切れ目を挟んだ粘着テープを互いに繋ぎ合わせる効果が発揮されることにより、未切断部をさらに短くしても、テープ割れが起きない。 According to this, by using a predetermined strong adhesive material, the effect of joining the adhesive tapes between which the strong adhesive material sandwiches the cut is exhibited, so that even if the uncut portion is further shortened, the tape cracks I don't get up.

次ぎに、本発明の一実施形態に係る粘着テープロールについて図面を参照しながら説明する。図1は本発明の一実施形態に係る粘着テープロールの斜視図であり、図2は、図1のA−A線断面図である。   Next, an adhesive tape roll according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an adhesive tape roll according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG.

この粘着テープロール1は、テープ状基材21の一方の面に粘着面22が形成された粘着テープ2を、その粘着面22が表側(図1では上面側)を向くように巻芯3に沿ってロール状に巻回したものからなる。   The pressure-sensitive adhesive tape roll 1 has a pressure-sensitive adhesive tape 2 having a pressure-sensitive adhesive surface 22 formed on one surface of a tape-like base material 21 and a core 3 with the pressure-sensitive adhesive surface 22 facing the front side (the upper surface side in FIG. 1). It consists of what was wound in roll shape along.

通常、巻芯3にはボール紙製の巻芯が用いられているが、これ以外に合成樹脂製など他の材質であってもよい。また、巻芯3を使わずに粘着テープ2のみをロール状に巻回する、いわゆるコアレスタイプであってもよく、本発明において、巻芯3はあくまで任意的な構成要素である。   Usually, a core made of cardboard is used for the core 3, but other materials such as a synthetic resin may be used. In addition, a so-called coreless type in which only the adhesive tape 2 is wound in a roll shape without using the core 3 may be used, and in the present invention, the core 3 is an arbitrary component.

基材21は例えば紙製で、図2に示すように、一方の面(表面)には粘着材が一様に塗布された粘着面22が形成されており、基材21の粘着面22の両端には、粘着材が塗布されていない未粘着部(ドライエッジ)23,23が設けられている。本発明において、未粘着部23,23は任意的な構成要素である。   The base material 21 is made of, for example, paper. As shown in FIG. 2, an adhesive surface 22 on which an adhesive material is uniformly applied is formed on one surface (surface). At both ends, non-adhesive portions (dry edges) 23 and 23 to which no adhesive material is applied are provided. In the present invention, the non-adhesive portions 23 and 23 are optional components.

粘着面22の粘着材は、単位面積当たりの引張強度が10〜100N/cmの強粘着材からなることが好ましく、より好ましくは、25〜80N/cmの範囲内であることが好ましい。具体的にはSIS(スチレン−イソプレン−スチレン)系粘着材にSBS(スチレン−ブタジエン)系粘着材を混合した強粘着材が好ましい。 The pressure-sensitive adhesive material of the pressure-sensitive adhesive surface 22 is preferably made of a strong pressure-sensitive adhesive material having a tensile strength per unit area of 10 to 100 N / cm 2 , and more preferably within a range of 25 to 80 N / cm 2 . Specifically, a strong adhesive material obtained by mixing an SIS (styrene-isoprene-styrene) adhesive material with an SBS (styrene-butadiene) adhesive material is preferable.

また、粘着材は基材21に対して層厚さTがT=0.01〜0.05mmの範囲で一様に塗布されていることが好ましい。これによれば、強粘着材の粘着力によって基材2が切れ目4に沿って切り離れるのを補助的に抑えることにより、より手切れ性のよい切れ目4を採用することができる。   Moreover, it is preferable that the adhesive material is uniformly apply | coated with respect to the base material 21 in the range whose layer thickness T is T = 0.01-0.05 mm. According to this, the cut 4 having better hand cutting properties can be adopted by supplementarily suppressing the base material 2 from being cut along the cut 4 by the adhesive force of the strong adhesive material.

粘着テープ2には、粘着テープ2をほぼ1周長ごとに切断するための切れ目が幅方向に沿って設けられている。切れ目4は、粘着テープ2を貫通する切断部41と、隣接する切断部41,41の間に残された未切断部42とを交互に配置した、いわゆるミシン目構造を備えている。 The adhesive tape 2 is provided with cuts 4 along the width direction for cutting the adhesive tape 2 substantially every circumferential length. The cut 4 has a so-called perforation structure in which cut portions 41 penetrating the adhesive tape 2 and uncut portions 42 left between adjacent cut portions 41 and 41 are alternately arranged.

切断部41の長さをL1,未切断部42の長さをL2としたとき、切断部41の長さL1と未切断部42の長さL2は比率にしてL1:L2=1:0.75以下を満足するように形成されていることが好ましい。   When the length of the cut portion 41 is L1 and the length of the uncut portion 42 is L2, the length L1 of the cut portion 41 and the length L2 of the uncut portion 42 are in a ratio of L1: L2 = 1: 0. It is preferably formed so as to satisfy 75 or less.

この例において、切断部41の長さL1は、L1=2.0mmであり、未切断部42の長さL2は、L2=1.5mm(L1:L2=1:0.75)であるが、上記の比率を満足する条件内であれば、切断部41と未切断部42の長さは仕様に応じて任意に設定できる。   In this example, the length L1 of the cut portion 41 is L1 = 2.0 mm, and the length L2 of the uncut portion 42 is L2 = 1.5 mm (L1: L2 = 1: 0.75). The lengths of the cut part 41 and the uncut part 42 can be arbitrarily set according to the specifications as long as the above ratio is satisfied.

なお、この例において、切れ目は幅方向に沿って直線状に形成されているが、これ以外に斜め方向に沿って形成されていてもよいし、繰り出し方向に沿って階段状にずらされていてもよい。
In this example, the cut line 4 is formed in a straight line along the width direction, but may be formed along an oblique direction in addition to this, or may be shifted in a staircase pattern along the feeding direction. May be.

基材21の他方の面(裏面)には、基材21を薄く形成した場合の補強用としてのラミネートフィルム24が設けられている。この例において、ラミネートフィルム24はポリエチレン製の薄いフィルムからなり、基材21に一体的に設けられている。   On the other surface (back surface) of the base material 21, a laminate film 24 is provided for reinforcement when the base material 21 is formed thin. In this example, the laminate film 24 is made of a thin film made of polyethylene and is provided integrally with the base material 21.

通常、ラミネートフィルム24は、剥離材層41の粘着性をコントロールすることにより不要とすることもできる。なお、基材21がプラスチックフィルム製の場合は、ラミネートフィルム24は不要である。   Usually, the laminate film 24 can be made unnecessary by controlling the adhesiveness of the release material layer 41. In addition, when the base material 21 is a plastic film, the laminate film 24 is unnecessary.

この例において、切れ目4は、粘着テープ2をロール状に巻き取ったのち、多数の刺入刃が櫛状に設けられたカッター(ともに図示しない)を粘着テープロール1の半径方向に沿って外側から内側に向けて差し込むことにより形成されるが、これ以外に、粘着テープ2の巻回と同時に行ってもよい。   In this example, the cut 4 is formed by winding the adhesive tape 2 in a roll shape, and then removing a cutter (not shown) having a large number of insertion blades in a comb shape along the radial direction of the adhesive tape roll 1. However, it may be performed simultaneously with the winding of the adhesive tape 2.

この例において、粘着材面22は基材21のほぼ全面に粘着面が一様に塗布された、いわゆるベタ塗りであるが、筋状に塗布されたものであってもよい。その場合、粘着材の塗布幅をコントロールして、粘着材層上に切れ目4の未切断部42が存在するようにする必要がある。   In this example, the adhesive material surface 22 is a so-called solid coating in which the adhesive surface is uniformly applied to almost the entire surface of the base material 21, but it may be applied in a streak shape. In that case, it is necessary to control the application width of the adhesive material so that the uncut portion 42 of the cut 4 exists on the adhesive material layer.
