Abstract

PROBLEM TO BE SOLVED: To provide a stretch label in which through-holes of a tear-off dot line are hardly connected with each other when diameters thereof are expanded, thereby preventing a hole from being formed, and that can be easily torn by hands.SOLUTION: The stretch label includes: a tubular body 2 in which a first side end 21 of a self-stretchable film is superimposed on a second side end 22 of the film, and the superimposed side ends are bonded to form a center seal 4; and a tear-off dot line 3 vertically formed from an upper end to a lower end of the tubular body 2. The length of a through-hole of the tear-off dot line 3 is 0.3-1.0 mm, and the length of an non-penetrated part between adjacent through-holes is 1.5-5.0 mm.

Description

本発明は、ストレッチラベルに関する。   The present invention relates to a stretch label.

ストレッチラベルは、拡張力を加えることによって拡径し、拡径させた状態で被着体に嵌挿し、その後、拡張力を解除することによって復元して被着体に装着され得る筒状ラベルである。ストレッチラベルは、ストレッチ筒状ラベル、自己伸縮性筒状ラベルとも呼ばれる。   The stretch label is a cylindrical label that is expanded by applying an expansion force, inserted into an adherend in the expanded state, and then restored by releasing the expansion force and can be attached to the adherend. is there. The stretch label is also called a stretch cylindrical label or a self-expandable cylindrical label.

かかるストレッチラベルは、弾性力を有するフィルムの両側端部を重ね合わせ、その重ね合わせ部分を接着することにより形成された筒状体からなる(特許文献1)。
容器などの被着体に装着されたストレッチラベルは、使用後、リサイクルのために被着体と分別される。
Such a stretch label is formed of a cylindrical body formed by overlapping both end portions of an elastic film and bonding the overlapped portions (Patent Document 1).
A stretch label attached to an adherend such as a container is separated from the adherend for recycling after use.

消費者などがストレッチラベルと被着体を分別する場合には、ストレッチラベルを分断するが、ストレッチラベルにフィルム分断用ミシン目線を形成しておけば、手でも分断できる。   When a consumer separates a stretch label and an adherend, the stretch label is divided. However, if a perforation line for film separation is formed on the stretch label, it can be separated by hand.

しかしながら、分断用ミシン目線をストレッチラベルに設けると、被着体に装着すべくストレッチラベルを拡径したときに、ミシン目線の各貫通孔が拡がり、隣接する貫通孔同士が繋がる結果、ラベルが十分に復元せずに装着不良を起こしたり、或いは、不良品となる。このため、通常、ストレッチラベルには、分断用ミシン目線を形成しない。
特に、被着体に装着する際、大きく伸張させるストレッチラベルほど、拡径時にミシン目線の貫通孔が繋がり易い傾向にある。
However, if the perforation line for cutting is provided on the stretch label, when the diameter of the stretch label is expanded to be attached to the adherend, each through-hole of the perforation line expands and the adjacent through-holes are connected to each other. This causes a mounting failure without being restored, or a defective product. For this reason, the perforation line for a division | segmentation is not normally formed in a stretch label.
In particular, a stretch label that stretches greatly when attached to an adherend tends to be connected to a perforated through-hole at the time of diameter expansion.

本発明の目的は、拡径したときに分断用ミシン目線の貫通孔が繋がって穴を生じ難く、さらに、手で簡単に分断できる、ストレッチラベルを提供することである。   An object of the present invention is to provide a stretch label that is difficult to form a hole by connecting through holes of a perforation line for dividing when the diameter is expanded, and that can be easily divided by hand.

本発明者らは、上記課題の下、手で簡単にラベルを分断できる上、拡径したときに貫通孔が繋がらない分断用ミシン目線について鋭意研究した。拡径時に貫通孔が繋がらないようにするためには、貫通孔の形成間隔を長くすれば良いが、そうすると、そのミシン目線を利用してラベルを分断することが困難となる。また、ストレッチラベルの上下端部は、ストレッチラベルの弾性回復力により被着体に強く密着している上、ストレッチラベルは比較的柔らかいため、ストレッチラベルの上端部又は下端部を摘みにくい。このため、拡径時に貫通孔が繋がらないようなミシン目線を形成したとしても、ストレッチラベルの上端部又は下端部を摘んで引張り、ミシン目線を利用してストレッチラベルを分断することも困難である。   Under the above-mentioned problems, the present inventors have conducted extensive research on the perforation line for cutting, in which the label can be easily cut by hand and the through-hole is not connected when the diameter is increased. In order to prevent the through-holes from being connected at the time of diameter expansion, the formation interval of the through-holes may be increased. However, it becomes difficult to divide the label using the perforation line. In addition, the upper and lower end portions of the stretch label are in close contact with the adherend due to the elastic recovery force of the stretch label, and the stretch label is relatively soft, so that it is difficult to pick the upper end portion or the lower end portion of the stretch label. For this reason, even if the perforation line is formed so that the through-hole is not connected at the time of diameter expansion, it is difficult to pick and pull the upper end part or the lower end part of the stretch label and to divide the stretch label using the perforation line. .

本発明者らは、かかる知見を得て、ストレッチラベルの上端部又は下端部を摘み、これを引張ってストレッチラベルを分断するものではなく、分断用ミシン目線を境にしてその両側をストレッチラベルの周方向に互いに離反する方向に引裂き力を加えることによって、ミシン目線からストレッチラベルを分断する方法に想到した。
本発明は、かかる分断方法によって手で簡単に分断でき且つ拡径時に貫通孔が繋がらない分断用ミシン目線を有するストレッチラベルを創作したものである。
The present inventors obtained such knowledge, picked the upper end portion or the lower end portion of the stretch label, and did not pull the stretch label to divide the stretch label. The inventors have come up with a method for separating a stretch label from a perforation line by applying a tearing force in a direction away from each other in the circumferential direction.
The present invention has created a stretch label having a perforation line for cutting that can be easily cut by hand by such a cutting method and that does not connect a through hole when the diameter is expanded.

本発明のストレッチラベルは、自己伸縮性フィルムの第1側端部に第2側端部を重ね合わせ、その重ね合わせ部分を接着してセンターシール部が形成された筒状体と、前記筒状体の上端部から下端部にかけて縦方向に形成された分断用ミシン目線と、を有し、前記自己伸縮性フィルムの厚み(mm)をX、分断用ミシン目線の貫通孔の長さ(mm)をY、分断用ミシン目線の隣接する貫通孔の間にある非貫通部の長さ(mm)をZとした場合、5X≦Y≦22.5X+0.075、−110X+7.3≦Z≦−150X+13、及び、0.01≦X≦0.08の関係を満たしている。   The stretch label of the present invention includes a tubular body in which a second side end is overlapped with a first side end of a self-stretchable film and a center seal portion is formed by bonding the overlapped portion, and the tubular shape A perforation line for cutting formed in the vertical direction from the upper end to the lower end of the body, the thickness (mm) of the self-stretchable film is X, and the length of the through hole of the perforation line for cutting (mm) Is Y, and the length (mm) of the non-penetrating portion between adjacent through holes of the dividing perforation line is Z, 5X ≦ Y ≦ 22.5X + 0.075, −110X + 7.3 ≦ Z ≦ −150X + 13 And 0.01 ≦ X ≦ 0.08.

本発明の好ましいストレッチラベルは、前記分断用ミシン目線が、前記第1側端部の縁に対応するセンターシール部の第1縁から周方向に3mm未満の領域以外及び前記第2側端部の縁に対応するセンターシール部の第2縁から周方向に3mm未満の領域以外の領域に形成されている。
本発明の好ましいストレッチラベルは、前記筒状体の表面に、摩擦抵抗の大きい高摩擦面と、それよりも摩擦抵抗の小さい低摩擦面と、が設けられており、前記高摩擦面が、前記分断用ミシン目線を基準にして、周方向一方側及び周方向他方側の少なくとも何れか一方に部分的に設けられている。
In a preferred stretch label of the present invention, the dividing perforation line is a region other than a region less than 3 mm in the circumferential direction from the first edge of the center seal portion corresponding to the edge of the first side end portion, and the second side end portion. It is formed in a region other than a region less than 3 mm in the circumferential direction from the second edge of the center seal portion corresponding to the edge.
In a preferred stretch label of the present invention, a surface of the cylindrical body is provided with a high friction surface having a high frictional resistance and a low friction surface having a lower frictional resistance than the high friction surface, With reference to the dividing perforation line, it is partially provided on at least one of the circumferential one side and the other circumferential side.

本発明の好ましいストレッチラベルは、前記筒状体には、さらに、補助ミシン目線が形成されており、前記補助ミシン目線は、前記筒状体の上端部又は下端部から分断用ミシン目線の中途部又はその近傍にまで筒状体の周方向に対して斜めに形成されている。   In the preferable stretch label of the present invention, an auxiliary perforation line is further formed in the cylindrical body, and the auxiliary perforation line is a middle part of the perforation line for separation from an upper end portion or a lower end portion of the cylindrical body. Or it forms diagonally with respect to the circumferential direction of a cylindrical body to the vicinity.

本発明のストレッチラベルは、拡径時に隣接する貫通孔が繋がって穴を生じ難い。
また、本発明のストレッチラベルを被着体に装着した後には、分断用ミシン目線を境にしてストレッチラベルの周方向一方側及び周方向他方側に指先を当て、互い離反する方向にスライドさせることにより、分断用ミシン目線に沿って裂け目が生じるから、ストレッチラベルを容易に分断できる。
In the stretch label of the present invention, adjacent through holes are connected at the time of diameter expansion, and it is difficult to produce a hole.
In addition, after the stretch label of the present invention is attached to the adherend, the fingertips are applied to the circumferential direction one side and the circumferential direction other side of the stretch label with the dividing perforation line as a boundary, and are slid in directions away from each other. Since a tear arises along the perforation line for parting, the stretch label can be easily parted.

図1乃至図4において、本発明のストレッチラベル1は、筒状にした自己伸縮性フィルムからなる筒状体2と、前記筒状体2の面内に形成された分断用ミシン目線3と、を有する。
筒状体2は、自己伸縮性フィルムを丸め、その第1側端部21の表面上に第2側端部22の裏面を重ね合わせ、その重ね合わせ部分を接着することにより構成されている。前記接着方法としては、接着剤などを用いた接着、ヒートシールなどが挙げられる。

本発明では、自己伸縮性フィルムの第1側端部21と第2側端部22の重ね合わせ部分のうち、両側端部が接着された部分をセンターシール部4という。
センターシール部4の幅(周方向長さ)は、特に限定されないが、0.2mm〜10mm程度であり、好ましくは、0.3mm〜5mmであり、より好ましくは、0.4mm〜2.0mmである。
In FIG. 1 thru | or FIG. 4, the stretch label 1 of this invention is the cylindrical body 2 which consists of a cylindrical self-stretchable film, The perforation line 3 for cutting formed in the surface of the said cylindrical body 2, Have
The cylindrical body 2 is configured by rolling a self-stretchable film, overlaying the back surface of the second side end portion 22 on the surface of the first side end portion 21, and bonding the overlapped portion. Examples of the bonding method include bonding using an adhesive, heat sealing, and the like.
This overlapped and bonded portion is generally called a center seal portion. In the illustrated example, the center seal portion 4 is configured by overlapping the back surface of the second side end portion 22 on the surface of the first side end portion 21 and bonding the overlapped portion. For example, the center seal portion overlaps the back surface of the second side end portion 22 on the back surface of the first side end portion 21 and adheres this overlapping portion, or the center seal portion of the first side end portion 21 The surface of the 2nd side edge part 22 may be overlap | superposed on the surface, and you may be comprised by adhere | attaching this overlapping part (such a center seal | sticker part is a hand-pasting type).
In the present invention, among the overlapping portions of the first side end portion 21 and the second side end portion 22 of the self-stretchable film, a portion where both end portions are bonded is referred to as the center seal portion 4.
The width (circumferential length) of the center seal portion 4 is not particularly limited, but is about 0.2 mm to 10 mm, preferably 0.3 mm to 5 mm, and more preferably 0.4 mm to 2.0 mm. It is.

分断用ミシン目線3は、筒状体2の縦方向と平行に延びて形成されている。分断用ミシン目線3の本数は特に限定されないが、好ましくは1本である。本発明の分断方法によれば、分断用ミシン目線3が少なくとも1本形成されていれば、それを利用して装着されたストレッチラベル1を分断できるので、分断用ミシン目線3を敢えて多数本設ける必然性がない上、分断用ミシン目線3を多数設けると、ラベルのデザインを損ねるからである。
1本の分断用ミシン目線3は、前記筒状体2の上端部から下端部にまで形成されている。
The dividing perforation line 3 is formed to extend in parallel with the longitudinal direction of the cylindrical body 2. The number of perforation lines 3 for cutting is not particularly limited, but is preferably one. According to the dividing method of the present invention, if at least one dividing perforation line 3 is formed, the attached stretch label 1 can be divided by using it, and therefore a large number of dividing perforation lines 3 are provided. This is because there is no necessity, and if a large number of dividing perforations 3 are provided, the design of the label is impaired.
One dividing perforation line 3 is formed from the upper end to the lower end of the cylindrical body 2.

この分断用ミシン目線3は、自己伸縮性フィルムの第1側端部21の縁に対応するセンターシール部4の第1縁41から周方向に3mm未満の領域51以外(好ましくは5mm未満の領域以外)及び自己伸縮性フィルムの第2側端部22の縁に対応するセンターシール部4の第2縁42から周方向に3mm未満の領域52以外(好ましくは7mm未満の領域以外)の領域に形成されている。   The dividing perforation line 3 is a region other than the region 51 less than 3 mm in the circumferential direction from the first edge 41 of the center seal portion 4 corresponding to the edge of the first side end portion 21 of the self-stretchable film (preferably a region less than 5 mm). Other than the region 52 less than 3 mm (preferably other than the region less than 7 mm) in the circumferential direction from the second edge 42 of the center seal portion 4 corresponding to the edge of the second side end portion 22 of the self-stretchable film. Is formed.

換言すると、自己伸縮性フィルムの第1側端部21の縁に対応するセンターシール部4の第1縁41から周方向一方側に3mm未満ずれた領域51(好ましくは5mm未満ずれた領域)、及び、自己伸縮性フィルムの第2側端部22の縁に対応するセンターシール部4の第2縁42から周方向他方側に3mm未満ずれた領域52(好ましくは7mm未満ずれた領域)、並びに、センターシール部4には、それぞれ分断用ミシン目線3が設けられていない。そして、センターシール部4の第1縁41から周方向一方側に3mm以上ずれ、好ましくは5mm以上ずれ、且つ、センターシール部4の第2縁42から周方向他方側に3mm以上ずれ、好ましくは7mm以上ずれた領域内に、分断用ミシン目線3が設けられている。
以下、筒状体2の中で、センターシール部4の第1縁41から周方向一方側に3mm未満(好ましくは5mm未満)ずれた領域を、第1領域51といい、センターシール部4の第2縁42から周方向他方側に3mm未満(好ましくは7mm未満)ずれた領域を、第2領域52という。
In other words, a region 51 (preferably a region shifted by less than 5 mm) that is shifted by less than 3 mm from the first edge 41 of the center seal portion 4 corresponding to the edge of the first side end portion 21 of the self-stretchable film to one side in the circumferential direction, And the area | region 52 (preferably area | region which shifted | deviated less than 7 mm) shifted | deviated less than 3 mm from the 2nd edge 42 of the center seal | sticker part 4 corresponding to the edge of the 2nd side edge part 22 of a self-stretchable film to the other circumferential direction, and The center seal portion 4 is not provided with the dividing perforation line 3. Further, the center seal portion 4 is shifted from the first edge 41 by 3 mm or more to one side in the circumferential direction, preferably 5 mm or more, and the center seal portion 4 is shifted from the second edge 42 to the other circumferential direction by 3 mm or more, preferably A dividing perforation line 3 is provided in a region shifted by 7 mm or more.
Hereinafter, a region of the cylindrical body 2 that is shifted by less than 3 mm (preferably less than 5 mm) in the circumferential direction from the first edge 41 of the center seal portion 4 is referred to as a first region 51. A region shifted by less than 3 mm (preferably less than 7 mm) from the second edge 42 to the other circumferential side is referred to as a second region 52.

筒状体2の第1領域51、及び、筒状体2の第2領域52に、分断用ミシン目線3を設けると、拡径時に、分断用ミシン目線3の貫通孔が繋がって穴を生じるおそれがあるからである。この理由は明確ではないが、自己伸縮性フィルムが重なったセンターシール部4は、その厚みが筒状体2の他の部分(自己伸縮性フィルムが重なっていない部分)よりも厚く、センターシール部4における自己伸縮性フィルムは伸張し難いので、ストレッチラベル1の伸張時にセンターシール部側から負荷を受けてしまうためと推定される。   When the dividing perforation line 3 is provided in the first region 51 of the cylindrical body 2 and the second region 52 of the cylindrical body 2, the through-holes of the dividing perforation line 3 are connected at the time of diameter expansion to form a hole. Because there is a fear. Although the reason for this is not clear, the center seal portion 4 on which the self-expandable film overlaps is thicker than the other portion of the cylindrical body 2 (the portion on which the self-expandable film does not overlap), and the center seal portion Since the self-stretchable film in 4 is difficult to stretch, it is estimated that a load is received from the center seal portion side when the stretch label 1 is stretched.

従って、分断用ミシン目線3は、センターシール部4の第1縁41から周方向一方側に3mm以上ずれ且つセンターシール部4の第2縁42から周方向他方側に3mm以上ずれた、領域に形成されていればよい。もっとも、分断用ミシン目線3を形成した箇所は、ラベルのデザインを損ねるので、分断用ミシン目線3はセンターシール部4にできるだけ近いことが好ましい。
このような観点から、分断用ミシン目線3は、センターシール部4の第1縁41から周方向一方側に3mm〜45mmずれた領域53内、又は、且つセンターシール部4の第2縁42から周方向他方側に3mm〜45mmずれた領域54内に形成されていることが好ましい。さらに、分断用ミシン目線3は、センターシール部4の第1縁41から周方向一方側に5mm〜40mmずれた領域53内、又は、且つセンターシール部4の第2縁42から周方向他方側に7mm〜40mmずれた領域54内に形成されていることがより好ましい。
本実施形態では、分断用ミシン目線3は、センターシール部4の第1縁41から周方向一方側に5mm〜40mmずれた領域53に形成されている。
Accordingly, the dividing perforation line 3 is in a region where the center seal portion 4 is displaced by 3 mm or more from the first edge 41 in the circumferential direction and 3 mm or more from the second edge 42 of the center seal portion 4 in the circumferential direction. It only has to be formed. However, since the portion where the dividing perforation line 3 is formed impairs the design of the label, the dividing perforation line 3 is preferably as close as possible to the center seal portion 4.
From such a point of view, the dividing perforation line 3 is located in the region 53 that is shifted from the first edge 41 of the center seal portion 4 to the one side in the circumferential direction by 3 mm to 45 mm, or from the second edge 42 of the center seal portion 4. It is preferably formed in a region 54 that is shifted by 3 mm to 45 mm on the other side in the circumferential direction. Further, the dividing perforation line 3 is in the region 53 that is shifted from the first edge 41 of the center seal portion 4 to the one circumferential side by 5 mm to 40 mm, or from the second edge 42 of the center seal portion 4 to the other circumferential side. More preferably, it is formed in the region 54 which is shifted by 7 mm to 40 mm.
In the present embodiment, the dividing perforation line 3 is formed in a region 53 that is shifted from the first edge 41 of the center seal portion 4 to the circumferential direction one side by 5 mm to 40 mm.

なお、筒状体2において、自己伸縮性フィルムの第1側端部21と第2側端部22の重ね合わせ部分の全体が接着されている場合には、センターシール部4の第1縁41及び第2縁42は、自己伸縮性フィルムの第1側端部21の縁及び第2側端部22の縁の位置に等しい。
自己伸縮性フィルムの第1側端部21と第2側端部22の重ね合わせ部分の周方向中央部が接着されている場合には、センターシール部4の第1縁41及び第2縁42は、前記第1側端部21の縁及び第2側端部22の縁よりもそれぞれ内側に位置する。
本実施形態では、図3に示すように、センターシール部4の第1縁41は第1側端部21の縁よりも内側に位置し、且つセンターシール部4の第2縁42は第2側端部22の縁と略一致している。
In addition, in the cylindrical body 2, when the whole overlapping part of the first side end portion 21 and the second side end portion 22 of the self-stretching film is bonded, the first edge 41 of the center seal portion 4 is used. And the 2nd edge 42 is equal to the position of the edge of the 1st side edge part 21 and the edge of the 2nd side edge part 22 of a self-expandable film.
When the center part in the circumferential direction of the overlapping portion of the first side end portion 21 and the second side end portion 22 of the self-stretchable film is bonded, the first edge 41 and the second edge 42 of the center seal portion 4 are attached. Are located inside the edge of the first side end 21 and the edge of the second side end 22, respectively.
In the present embodiment, as shown in FIG. 3, the first edge 41 of the center seal portion 4 is located inside the edge of the first side end portion 21, and the second edge 42 of the center seal portion 4 is the second. It substantially coincides with the edge of the side end 22.

さらに、筒状体2の面内には、補助ミシン目線6が形成されている。補助ミシン目線6は、分断時に切断起点となるミシン目線である。補助ミシン目線6の本数は特に限定されないが、好ましくは1本又は2本であり、より好ましくは1本である。補助ミシン目線6が少なくとも1本形成されていれば、それを起点として裂け目を生じさせ、その裂け目を分断用ミシン目線3に伝搬させることができ、他方、補助ミシン目線6を多数設けると、ラベルのデザインを損ねるからである。   Further, auxiliary perforation lines 6 are formed in the plane of the cylindrical body 2. The auxiliary perforation line 6 is a perforation line that becomes a starting point of cutting when dividing. The number of auxiliary perforation lines 6 is not particularly limited, but is preferably one or two, and more preferably one. If at least one auxiliary perforation line 6 is formed, a tear can be generated from that as a starting point and can be propagated to the perforation line 3 for splitting. This is because it will damage the design.

補助ミシン目線6は、その一端部6aが筒状体2の上端部に位置し、且つその他端部が分断用ミシン目線3の縦方向中途部又はその近傍に連設されている。
具体的には、補助ミシン目線6は、一端部6aが分断用ミシン目線3よりも周方向一方側又は周方向他方側に位置ずれしており、その一端部6aから下方に向かうに従って分断用ミシン目線3に近づくように傾斜している。従って、補助ミシン目線6は、隣接する各貫通孔が筒状体2の縦方向及び周方向の双方向に位置ずれし、補助ミシン目線6を全体として見れば、筒状体2の周方向に対して斜めに延びている。
One end 6 a of the auxiliary perforation line 6 is located at the upper end of the cylindrical body 2, and the other end is connected to the middle part in the longitudinal direction of the dividing perforation line 3 or in the vicinity thereof.
Specifically, the auxiliary perforation line 6 has one end portion 6a displaced to the one side in the circumferential direction or the other side in the circumferential direction from the perforation line 3 for cutting, and the cutting machine for cutting as it goes downward from the one end portion 6a. It is inclined so as to approach the line of sight 3. Therefore, the auxiliary perforation line 6 is located in the circumferential direction of the cylindrical body 2 when the adjacent through holes are displaced in both the longitudinal direction and the circumferential direction of the cylindrical body 2 and the auxiliary perforation line 6 is viewed as a whole. In contrast, it extends diagonally.

補助ミシン目線6の各貫通孔は、縦方向及び周方向において重ならずに位置ずれしている。
補助ミシン目線6の各貫通孔が縦方向において重ならずに位置ずれしているとは、補助ミシン目線6の任意の1つの貫通孔の上縁及び下縁を通り且つ縦方向と平行な仮想直線をそれぞれ引いたとき、その左右2本の仮想直線の間に、前記補助ミシン目線6の他の貫通孔が部分的又は全体的に重なっていないことをいう。補助ミシン目線6の各貫通孔が周方向において重ならずに位置ずれしているとは、補助ミシン目線6の任意の1つの貫通孔の上縁及び下縁を通り且つ周方向と平行な仮想直線をそれぞれ引いたとき、その上下2本の仮想直線の間に、前記補助ミシン目線6の他の貫通孔が部分的又は全体的に重なっていないことをいう。
このように補助ミシン目線6の各貫通孔を縦方向及び周方向に位置ずれさせることにより、ストレッチラベル1の拡径時に、補助ミシン目線6の隣接する貫通孔が繋がることを防止できる。
Each through hole of the auxiliary perforation line 6 is displaced without overlapping in the longitudinal direction and the circumferential direction.
The fact that each through hole of the auxiliary perforation line 6 is displaced without overlapping in the vertical direction means that the virtual perforation passes through the upper and lower edges of any one through hole of the auxiliary perforation line 6 and is parallel to the vertical direction. When a straight line is drawn, it means that the other through holes of the auxiliary perforation line 6 are not partially or entirely overlapped between the two left and right virtual lines. The fact that each through hole of the auxiliary perforation line 6 is displaced without overlapping in the circumferential direction means that the virtual perforation passes through the upper and lower edges of any one through hole of the auxiliary perforation line 6 and is parallel to the circumferential direction. When each straight line is drawn, it means that the other through holes of the auxiliary perforation line 6 do not partially or entirely overlap between the two upper and lower virtual straight lines.
Thus, by shifting the positions of the through holes of the auxiliary perforation line 6 in the longitudinal direction and the circumferential direction, it is possible to prevent the adjacent through holes of the auxiliary perforation line 6 from being connected when the diameter of the stretch label 1 is increased.

なお、補助ミシン目線6の一端部6aにある貫通孔は、図4に示すように、(筒状体2の上端に位置せず)筒状体2の上端から僅かに離れていることが好ましい。補助ミシン目線6の一端部6aの貫通孔が筒状体2の上端に位置すると、筒状体2の上端が少し欠けるので、ストレッチラベル1の拡径時に、その欠けた上端から引き裂きが生じるおそれがある。
補助ミシン目線6の一端部6aにある貫通孔の上縁と筒状体2の上端2aとの間隔は、0.5mm〜4mmであることが好ましい。なお、前記間隔は、補助ミシン目線6の一端部6aの貫通孔の上縁と筒状体2の上端2aとの間の縦方向長さである。
なお、本実施形態の筒状体2においては、その上端2aの延びる方向と周方向とは平行である。また、筒状体2の縦方向は、前記上端2aの延びる方向と直交する方向である。
In addition, as shown in FIG. 4, it is preferable that the through-hole in the one end part 6a of the auxiliary perforation line 6 is slightly separated from the upper end of the cylindrical body 2 (not located at the upper end of the cylindrical body 2). . When the through hole of the one end portion 6a of the auxiliary perforation line 6 is located at the upper end of the cylindrical body 2, the upper end of the cylindrical body 2 is slightly chipped, so that when the diameter of the stretch label 1 is increased, tearing may occur from the chipped upper end. There is.
The distance between the upper edge of the through hole in the one end portion 6a of the auxiliary perforation line 6 and the upper end 2a of the cylindrical body 2 is preferably 0.5 mm to 4 mm. The interval is the length in the vertical direction between the upper edge of the through hole of the one end portion 6 a of the auxiliary perforation line 6 and the upper end 2 a of the cylindrical body 2.
In addition, in the cylindrical body 2 of this embodiment, the direction where the upper end 2a extends and the circumferential direction are parallel. The longitudinal direction of the cylindrical body 2 is a direction orthogonal to the extending direction of the upper end 2a.

また、補助ミシン目線6の他端部6bは分断用ミシン目線3の中途部の近傍にまで設けられている。図4に示すように、この補助ミシン目線6の他端部6bにある貫通孔と分断用ミシン目線3の貫通孔は、繋がっていないことが好ましい。例えば、補助ミシン目線6の他端部6bにある貫通孔は、分断用ミシン目線3の縦方向中途部にある1つの非貫通部(分断用ミシン目線3の縦方向中途部にある2つの貫通孔の間)に配置されていると、補助ミシン目線6と分断用ミシン目線3との間隔が十分に確保できないので、ストレッチラベル1の拡径時に、補助ミシン目線6の他端部6bの貫通孔と分断用ミシン目線3の貫通孔が繋がって穴が生じるおそれがある。
この場合、補助ミシン目線6の他端部6bの貫通孔と分断用ミシン目線3の貫通孔の間隔は、0.5mm〜3.0mmが好ましい。なお、前記間隔は、補助ミシン目線6の他端部6bの貫通孔の縁(他端部6bの貫通孔の縁のうち任意の一点)と分断用ミシン目線3の貫通孔の縁(近接する分断用ミシン目線3の貫通孔の縁のうち任意の一点)との最小直線長さである。
Further, the other end portion 6 b of the auxiliary perforation line 6 is provided in the vicinity of the middle part of the cutting perforation line 3. As shown in FIG. 4, it is preferable that the through hole in the other end 6b of the auxiliary perforation line 6 and the through hole of the dividing perforation line 3 are not connected. For example, the through hole in the other end portion 6 b of the auxiliary perforation line 6 has one non-penetration portion (two penetrations in the middle portion in the vertical direction of the dividing perforation line 3). Since the space between the auxiliary perforation line 6 and the dividing perforation line 3 cannot be sufficiently secured, the other end portion 6b of the auxiliary perforation line 6 penetrates when the diameter of the stretch label 1 is increased. There is a possibility that a hole is formed by connecting the hole and the through hole of the perforation line 3 for cutting.
In this case, the distance between the through hole of the other end portion 6b of the auxiliary perforation line 6 and the through hole of the dividing perforation line 3 is preferably 0.5 mm to 3.0 mm. In addition, the said space | interval is the edge (adjacent one point of the edge of the through-hole of the other end part 6b) of the through-hole of the other end part 6b of the auxiliary | assistant perforation line 6 and the edge (adjacent to the through-hole of the dividing perforation line 3). It is the minimum straight line length with any one of the edges of the through hole of the perforation line 3 for cutting.

補助ミシン目線6の周方向に対する傾斜角は特に限定されないが、分断時に裂け目が生じ易く且つその裂け目が分断用ミシン目線3に伝搬し易いことから、補助ミシン目線6の周方向(筒状体2の上縁)に対する角度αは、30度〜60度が好ましく、40度〜60度がより好ましい。   The angle of inclination of the auxiliary perforation line 6 with respect to the circumferential direction is not particularly limited. However, since a tear is likely to occur at the time of division and the tear is easy to propagate to the perforation line 3 for separation, The angle α with respect to the upper edge) is preferably 30 ° to 60 °, more preferably 40 ° to 60 °.

補助ミシン目線6は、分断用ミシン目線3を基準にして、その周方向一方側及び周方向他方側の何れの側に位置していてもよい。好ましくは、補助ミシン目線6は、分断用ミシン目線3と同様に、筒状体2の第1領域51、第2領域52及びセンターシール部4以外の領域に設けられている。
ラベルのデザインを考慮すると、補助ミシン目線6は、センターシール部4の第1縁41から周方向一方側に3mm〜45mmずれた領域53内、又は、且つセンターシール部4の第2縁42から周方向他方側に3mm〜45mmずれた領域54内に形成されていることがより好ましい。さらに、補助ミシン目線6は、センターシール部4の第1縁41から周方向一方側に5mm〜40mmずれた領域53内、又は、且つセンターシール部4の第2縁42から周方向他方側に7mm〜40mmずれた領域54内に形成されていることが特に好ましい。
本実施形態では、補助ミシン目線6は、分断用ミシン目線3の周方向一方側であって、センターシール部4の第1縁41から周方向一方側に5mm〜40mmずれた領域54に形成されている。
The auxiliary perforation line 6 may be located on either the circumferential direction one side or the circumferential direction other side with reference to the dividing perforation line 3. Preferably, the auxiliary perforation line 6 is provided in a region other than the first region 51, the second region 52, and the center seal portion 4 of the cylindrical body 2, similarly to the cutting perforation line 3.
Considering the design of the label, the auxiliary perforation line 6 is located in the region 53 that is shifted from the first edge 41 of the center seal part 4 to the circumferential side by 3 mm to 45 mm or from the second edge 42 of the center seal part 4. More preferably, it is formed in a region 54 shifted by 3 mm to 45 mm on the other side in the circumferential direction. Further, the auxiliary perforation line 6 is located in the region 53 that is shifted from the first edge 41 of the center seal portion 4 to the one side in the circumferential direction by 5 mm to 40 mm, or from the second edge 42 of the center seal portion 4 to the other side in the circumferential direction. It is particularly preferable that the film is formed in the region 54 shifted by 7 mm to 40 mm.
In the present embodiment, the auxiliary perforation line 6 is formed in a region 54 that is one side in the circumferential direction of the cutting perforation line 3 and that is shifted from the first edge 41 of the center seal portion 4 to the one side in the circumferential direction by 5 mm to 40 mm. ing.

分断用ミシン目線3及び補助ミシン目線6は、それぞれ、ミシン針の縫い跡の如く筒状体2(自己伸縮性フィルム)の表裏面に貫通する貫通孔が断続的に形成された線である。従って、分断用ミシン目線3及び補助ミシン目線6は、複数の貫通孔と、前記複数の貫通孔の間に存在する非貫通部(貫通処理されていないフィルム部分)と、からなり、これら複数の貫通孔及び非貫通部が交互に連なった集合である。分断用ミシン目線3及び補助ミシン目線6のそれぞれの端部は、分断用ミシン目線3及び補助ミシン目線6のそれぞれ最も端にある貫通孔に相当する。   Each of the perforation line 3 for cutting and the auxiliary perforation line 6 is a line in which through-holes penetrating through the front and back surfaces of the cylindrical body 2 (self-stretchable film) are intermittently formed like a sewing mark of a sewing needle. Accordingly, the dividing perforation line 3 and the auxiliary perforation line 6 are composed of a plurality of through holes and a non-penetrating part (a film part not subjected to the penetration process) existing between the plurality of through holes. It is a set in which through holes and non-penetrating portions are alternately connected. The respective end portions of the dividing perforation line 3 and the auxiliary perforation line 6 correspond to the through holes at the extreme ends of the dividing perforation line 3 and the auxiliary perforation line 6, respectively.

なお、分断用ミシン目線3が筒状体2の縦方向に延びるとは、その各貫通孔の重心を結んだ仮想線が筒状体2の縦方向と平行に延びているという意味である。また、補助ミシン目線6が筒状体2の周方向に対して斜めに延びるとは、その各貫通孔の重心を結んだ仮想線が筒状体2の周方向に対して傾斜して延びているという意味である。補助ミシン目線6は、図示したように、直線状に斜めに延びていてもよいし、図示しないが、曲線状又は折れ線状に斜めに延びていてもよい。
前記分断用ミシン目線3及び補助ミシン目線6の各貫通孔の重心は、それらの貫通孔が直線状又は複数の直線の交差状である場合には、その直線を拡大して面積を観念したときの重心を意味する。
Note that the dividing perforation line 3 extending in the longitudinal direction of the cylindrical body 2 means that a virtual line connecting the centers of gravity of the through holes extends in parallel with the longitudinal direction of the cylindrical body 2. Further, the auxiliary perforation line 6 extending obliquely with respect to the circumferential direction of the cylindrical body 2 means that an imaginary line connecting the center of gravity of each through-hole extends obliquely with respect to the circumferential direction of the cylindrical body 2. It means that As illustrated, the auxiliary perforation line 6 may extend obliquely in a straight line shape, or may extend obliquely in a curved line shape or a broken line shape (not illustrated).
The center of gravity of each through hole of the dividing perforation line 3 and the auxiliary perforation line 6 is when the through hole is a straight line or an intersection of a plurality of straight lines, and the area is enlarged by enlarging the straight line Means the center of gravity.

貫通孔の正面視形状としては、円形状(楕円形状を含む)、線状(直線状、曲線状、屈曲線状など)、2つ以上の直線、曲線又は屈曲線が交差した形状(クロス状、鏃状など)などが挙げられるが、直線状が好ましい。直線状の貫通孔は、ミシン目刃などで形成容易である上、それに沿って筒状体2を分断し易い。
分断用ミシン目線3の各貫通孔が直線状である場合、その直線状の貫通孔自体は、それぞれ、筒状体2の縦方向に対して傾斜していてもよいが、通常、その直線状の貫通自体も筒状体2の縦方向と平行に形成される。
補助ミシン目線6の各貫通孔が直線状である場合、その直線状の貫通孔自体は、それぞれ、筒状体2の周方向又は縦方向に平行に形成されていてもよいが、通常、その直線状の貫通孔自体も、筒状体2の周方向及び縦方向に傾斜して形成される。つまり、前記補助ミシン目線6の直線状の各貫通孔は、その直線が補助ミシン目線6が延びる方向と平行に延びている。
As the front view shape of the through hole, a circular shape (including an elliptical shape), a linear shape (straight shape, a curved shape, a bent line shape, etc.), a shape in which two or more straight lines, a curved line, or a bent line intersect (cross shape) , And the like), and a straight line shape is preferable. The straight through-hole can be easily formed with a perforated blade or the like, and the cylindrical body 2 is easily divided along the straight through-hole.
When each through hole of the dividing perforation line 3 is linear, each of the linear through holes themselves may be inclined with respect to the longitudinal direction of the cylindrical body 2, but usually the linear shape The penetration itself is also formed parallel to the longitudinal direction of the cylindrical body 2.
When each through-hole of the auxiliary perforation line 6 is linear, the linear through-hole itself may be formed in parallel to the circumferential direction or the vertical direction of the cylindrical body 2 respectively. The straight through hole itself is also formed to be inclined in the circumferential direction and the vertical direction of the cylindrical body 2. That is, each straight through hole of the auxiliary perforation line 6 extends in parallel with the direction in which the auxiliary perforation line 6 extends.

分断用ミシン目線3及び補助ミシン目線6の貫通孔は、ミシン目刃(ディスクカッターなど)の機械的手段、レーザーなどの熱的手段などの各種切断手段を用いて形成できる。好ましくは、分断用ミシン目線3及び補助ミシン目線6は、機械的手段で形成される。   The through holes of the perforation line 3 for cutting and the auxiliary perforation line 6 can be formed by using various cutting means such as mechanical means of a perforation blade (such as a disk cutter) and thermal means such as a laser. Preferably, the dividing perforation line 3 and the auxiliary perforation line 6 are formed by mechanical means.

分断用ミシン目線3の貫通孔の長さY(1つの貫通孔の上縁から下縁までの縦方向長さ)は、式1:5X≦Y≦22.5X+0.075を満たし、分断用ミシン目線3の隣接する貫通孔の間にある非貫通部の長さZ(隣合った2つの貫通孔であって、上側の貫通孔の下縁から下側の貫通孔の上縁までの縦方向長さ)は、式2:−110X+7.3≦Z≦−150X+13を満たす。
但し、前記式1及び式2において、貫通孔の長さY及び非貫通部の長さZの単位はmmであり、Xは、式3:0.01≦X≦0.08の範囲を満たす、自己伸縮性フィルムの厚み(単位mm)を示す。
The length Y of the through hole of the cutting perforation line 3 (the length in the vertical direction from the upper edge to the lower edge of one through hole) satisfies the formula 1: 5X ≦ Y ≦ 22.5X + 0.075, Length Z of the non-penetrating portion between adjacent through holes of line of sight 3 (the two adjacent through holes, the vertical direction from the lower edge of the upper through hole to the upper edge of the lower through hole The length) satisfies the formula 2: −110X + 7.3 ≦ Z ≦ −150X + 13.
However, in the formula 1 and the formula 2, the unit of the length Y of the through hole and the length Z of the non-penetrating portion is mm, and X satisfies the range of the formula 3: 0.01 ≦ X ≦ 0.08. The thickness (unit: mm) of the self-stretchable film is shown.

なお、分断用ミシン目線3を構成する複数の貫通孔の長さ及び非貫通部の長さは、それぞれ上記範囲内であれば異なっていてもよいが、通常、1つの分断用ミシン目線3を構成する複数の貫通孔の長さは、同じとされ、その複数の非貫通部の長さも同じとされていることが好ましい。
例えば、厚み50μmの自己伸縮性フィルムから形成されるストレッチラベルの場合、分断用ミシン目線3の貫通孔の長さは、0.25mm〜1.2mmであり、好ましくは、0.3mm〜1.0mmであり、より好ましくは、0.3mm〜0.7mmであり、特に好ましくは、0.3mm〜0.6mmである。また、厚み50μmの自己伸縮性フィルムから形成されるストレッチラベルの場合、分断用ミシン目線3の非貫通部の長さは、1.8mm〜5.5mmであり、好ましくは、1.5mm〜5.0mmであり、より好ましくは、3.5mm〜4.5mmである。
The lengths of the plurality of through holes and the lengths of the non-penetrating portions constituting the dividing perforation line 3 may be different from each other as long as they are within the above ranges. It is preferable that the lengths of the plurality of through holes to be configured are the same, and the lengths of the plurality of non-through holes are also the same.
For example, in the case of a stretch label formed from a self-stretchable film having a thickness of 50 μm, the length of the through hole of the perforation line 3 for cutting is 0.25 mm to 1.2 mm, preferably 0.3 mm to 1. 0 mm, more preferably 0.3 mm to 0.7 mm, and particularly preferably 0.3 mm to 0.6 mm. In the case of a stretch label formed from a self-stretchable film having a thickness of 50 μm, the length of the non-penetrating portion of the perforation line 3 for cutting is 1.8 mm to 5.5 mm, preferably 1.5 mm to 5 0.0 mm, and more preferably 3.5 mm to 4.5 mm.

補助ミシン目線6の貫通孔の長さ(1つの貫通孔の一縁(貫通孔の縁のうち任意の一点)から他縁(その貫通孔の縁のうち前記一縁を除いた任意の他の一点)までの直線長さのうちで最大の長さ)は、0.3mm〜1.0mmであり、好ましくは0.4mm〜0.8mmである。ただし、前記補助ミシン目線6の貫通孔の長さは、分断用ミシン目線3の貫通孔の長さよりも大きいことを条件とする。補助ミシン目線6の非貫通部の長さ(隣合った2つの貫通孔であって、上側の貫通孔の一縁(上側の貫通孔の縁のうち任意の一点)から下側の貫通孔の一縁(下側の貫通孔の縁のうち任意の一点)までの直線長さのうちで最小の長さ)は、0.5mm〜2.5mmであり、好ましくは、0.5mm〜1.5mmである。
なお、補助ミシン目線6を構成する複数の貫通孔の長さ及び非貫通部の長さは、それぞれ上記範囲内であれば異なっていてもよいが、1つの補助ミシン目線6を構成する複数の貫通孔の長さは、同じとされ、その複数の非貫通部の長さも同じとされていることが好ましい。
The length of the through hole of the auxiliary perforation line 6 (one edge of one through hole (any one of the edges of the through hole) to the other edge (any one of the edges of the through hole excluding the one edge) Among the straight line lengths up to one point), the maximum length) is 0.3 mm to 1.0 mm, preferably 0.4 mm to 0.8 mm. However, the length of the through hole of the auxiliary perforation line 6 is required to be larger than the length of the through hole of the dividing perforation line 3. The length of the non-penetrating portion of the auxiliary perforation line 6 (two adjacent through holes, from one edge of the upper through hole (any one of the edges of the upper through hole) to the lower through hole The minimum length among the straight lines up to one edge (any one of the edges of the lower through-hole) is 0.5 mm to 2.5 mm, preferably 0.5 mm to 1.mm. 5 mm.
The lengths of the plurality of through holes and the non-penetrating portions constituting the auxiliary perforation line 6 may be different as long as they are within the above ranges, but the plurality of the perforation lines constituting one auxiliary perforation line 6 may be different. It is preferable that the lengths of the through holes are the same, and the lengths of the plurality of non-through portions are also the same.

筒状体2の表面は、摩擦抵抗の大きい高摩擦面2Hと、それよりも摩擦抵抗の小さい低摩擦面2Lとされている。図1、図2及び図6において、便宜上、高摩擦面が設けられた範囲を薄墨塗りで示している。
高摩擦面2Hは、前記分断用ミシン目線3を基準にして、その周方向一方側及び周方向他方側の少なくとも何れか一方に部分的に設けられ、好ましくは、その周方向一方側及び周方向他方側の双方にそれぞれ部分的に設けられている。
筒状体2の表面のうち、前記高摩擦面2H以外は、低摩擦面2Lとされている。
The surface of the cylindrical body 2 is a high friction surface 2H having a large frictional resistance and a low friction surface 2L having a smaller frictional resistance. In FIG. 1, FIG. 2, and FIG. 6, the range where the high friction surface is provided is shown in light ink for convenience.
The high friction surface 2H is partially provided on at least one of the circumferential direction one side and the circumferential direction other side with reference to the dividing perforation line 3, and preferably, the circumferential direction one side and the circumferential direction. It is partially provided on both sides of the other side.
Of the surface of the cylindrical body 2, except the high friction surface 2H, it is set as the low friction surface 2L.

特に、高摩擦面2Hは、補助ミシン目線6と対応して設けられていることが好ましく、筒状体2の上端部に補助ミシン目線6が本実施形態にあっては、高摩擦面2Hは、筒状体2の上方部に設けられる。
より具体的には、高摩擦面2Hは、2箇所設けられ、各高摩擦面2Hは、分断用ミシン目線3の周方向一方側と分断用ミシン目線3の周方向他方側とに設けられており、さらに、補助ミシン目線6から離れて設けられていることが好ましい。
In particular, the high friction surface 2H is preferably provided in correspondence with the auxiliary perforation line 6, and when the auxiliary perforation line 6 is in the upper end of the cylindrical body 2, the high friction surface 2H is , Provided above the cylindrical body 2.
More specifically, two high friction surfaces 2H are provided, and each high friction surface 2H is provided on one side in the circumferential direction of the dividing perforation line 3 and on the other side in the circumferential direction of the dividing perforation line 3. Furthermore, it is preferable that the auxiliary perforation line 6 is provided apart from the auxiliary perforation line 6.

1つの高摩擦面2Hの大きさ(面積)は、概ね標準体型の成人の親指の指先大以上であり、例えば、5cm以上、好ましくは15cm以上である。 The size (area) of one high-friction surface 2H is generally larger than the fingertip size of a standard-type adult thumb, for example, 5 cm 2 or more, preferably 15 cm 2 or more.

高摩擦面2Hの静摩擦係数は、低摩擦面2Lの静摩擦係数よりも大きければ特に限定されない。
低摩擦面2Lの静摩擦係数は、例えば、0.25以下であり、好ましくは、0.15以下である。低摩擦面2Lの静摩擦係数の下限は、理論的には0であるが、実際は、0を越え、好ましくは0.05以上である。
The static friction coefficient of the high friction surface 2H is not particularly limited as long as it is larger than the static friction coefficient of the low friction surface 2L.
The static friction coefficient of the low friction surface 2L is, for example, 0.25 or less, and preferably 0.15 or less. The lower limit of the static friction coefficient of the low friction surface 2L is theoretically 0, but actually exceeds 0, preferably 0.05 or more.

前記静摩擦係数は、下記に示す測定方法によって測定された数値を言う。
測定対象となる高摩擦面又は低摩擦面が表面に形成された自己伸縮性フィルムを80mm×100mm(幅×長さ)に切り取り、摩擦面形成処理が成されていない同材料の自己伸縮性フィルムを100mm×300mm(幅×長さ)に切り取り、前記測定対象の高摩擦面又は低摩擦面を前記摩擦面形成処理が成されていない自己伸縮性フィルムに重ね、JIS K 7125に準じて、引張りスピード100mm/分、温度23±2℃、湿度50±5%で、静摩擦係数を測定する。
The static friction coefficient is a numerical value measured by the measurement method shown below.
A self-stretchable film of the same material that has not been subjected to a frictional surface forming process by cutting a self-stretchable film having a high-friction surface or a low-friction surface formed on the surface into 80 mm × 100 mm (width × length). Is cut into 100 mm × 300 mm (width × length), the high friction surface or the low friction surface of the measurement object is layered on the self-stretchable film not subjected to the friction surface formation treatment, and pulled according to JIS K 7125 The static friction coefficient is measured at a speed of 100 mm / min, a temperature of 23 ± 2 ° C., and a humidity of 50 ± 5%.

高摩擦面2Hは滑りにくいので、ストレッチラベル1の分断時、その高摩擦面2Hに指を当ててスライドさせるときに、指先がストレッチラベル1から滑ることを防止できる。
他方、補助ミシン目線6及び分断用ミシン目線3並びにそれらの周辺を含む筒状体2の表面の高摩擦面2H以外は、低摩擦面2Lとされているので、ストレッチラベル1が被着体に装着された包装体の搬送時に、分断用ミシン目線3又は補助ミシン目線6の各貫通孔が拡がることを防止できる。具体的には、包装体(ストレッチラベル1装着済み被着体)の搬送時、そのストレッチラベル1の表面に異物や隣接する他の包装体などが接触することによって、ストレッチラベル1に引張り力が加わる。この点、低摩擦面2Lが形成された筒状体2からなるストレッチラベル1は、その面に異物などが接触してもラベルに負荷が掛かり難いので、分断用ミシン目線3及び補助ミシン目線6の各貫通孔が不用意に破断することを防止できる。
Since the high friction surface 2H is difficult to slide, when the stretch label 1 is divided, the fingertip can be prevented from slipping from the stretch label 1 when sliding with the finger placed on the high friction surface 2H.
On the other hand, since the auxiliary perforation line 6 and the dividing perforation line 3 and the high friction surface 2H of the surface of the cylindrical body 2 including the periphery thereof are made the low friction surface 2L, the stretch label 1 is attached to the adherend. It is possible to prevent each through-hole of the dividing perforation line 3 or the auxiliary perforation line 6 from expanding when the mounted package is conveyed. Specifically, when the package (adhered body attached with the stretch label 1) is transported, the stretch label 1 has a tensile force due to contact of foreign matter or other adjacent packages with the surface of the stretch label 1.

The instantaneous strain can be measured as follows.
The self-stretchable film has a length of 15 ± 0.1 mm in the other direction (corresponding to the longitudinal direction of the tubular body) and a length of 200 mm in one direction (corresponding to the circumferential direction of the tubular body) (distance between marked lines 100 ±). 2 mm) rectangles to make sample pieces.

In the measurement, for example, using a constant crosshead speed type or pendulum type tensile tester (extension speed at the time of test: 50 mm / min), a predetermined load (N) is applied, and the distance between the marked lines of the sample pieces is predetermined. The distance between the marked lines is read when the load is returned to 0 (N). By substituting the measured value into the following formula, the instantaneous strain (%) is calculated.
Instantaneous strain (%) = 100 × ΔL2 / L2.
The L2 indicates the distance (mm) between the marked lines of the sample pieces before pulling, and the ΔL2 indicates the increase (mm) in the distance between the marked lines of the sample pieces when the load is returned after stretching.
The permanent strain (%) can be calculated by removing the distance from the marked line after removing from the testing machine after the tensile test and storing in a constant temperature bath at 23 ° C. for 4 weeks.

It is preferable that the instantaneous strain (6000 mm / min) after stretching is preferably 30% or less (preferably 1.75 times), and the instantaneous strain after stretching is 1.60 times (preferably 1.75 times). %, More preferably 1.60 times (preferably 1.75 times) the same, and an instantaneous strain after stretching of 18% or less is particularly preferred.

なお、前記自己伸縮性フィルムの伸張倍率の上限は、特に制限はないが、例えば、2.0倍以下である。また、前記自己伸縮性フィルムの瞬間歪みの下限は、理論上では零であるが、実際に零という場合は少ない。このため、前記自己伸縮性フィルムの瞬間歪みの下限は、0%を越え、好ましくは1%以上である。
前記伸張倍率は、伸張後の長さ/伸張前の長さ、で求められる。
The upper limit of the stretch ratio of the self-stretchable film is not particularly limited, but is, for example, 2.0 times or less. Further, the lower limit of the instantaneous strain of the self-stretchable film is theoretically zero, but it is rarely zero. For this reason, the lower limit of the instantaneous strain of the self-stretchable film exceeds 0%, preferably 1% or more.
The stretching magnification is obtained by the length after stretching / the length before stretching.

前記瞬間歪みは、次のようにして測定できる。
自己伸縮性フィルムを、他方向(筒状体の縦方向に相当)に長さ15±0.1mm、一方向(筒状体の周方向に相当)に長さ200mm(標線間距離100±2mm)の長方形に切り取り、サンプル片を作製する。このサンプル片の長辺方向を測定方向として、所定の伸張倍率(1.60倍又は1.75倍)になるまで引張り、サンプル片の標線間距離を測定する。
The instantaneous strain can be measured as follows.
The self-stretchable film has a length of 15 ± 0.1 mm in the other direction (corresponding to the longitudinal direction of the tubular body) and a length of 200 mm in one direction (corresponding to the circumferential direction of the tubular body) (distance between marked lines 100 ±). 2 mm) rectangles to make sample pieces. Using the long side direction of the sample piece as a measurement direction, the sample piece is pulled until a predetermined expansion ratio (1.60 times or 1.75 times) is obtained, and the distance between the marked lines of the sample piece is measured.

前記測定は、例えば、クロスヘッド速度一定型又は振子型引張試験機(試験時の伸張速度:50mm/分又は6000mm/分)を用いて、所定の荷重(N)を加えてサンプル片の標線間距離が、所定の倍率(1.60倍又は1.75倍)になるまで伸ばし、この直後に荷重を0(N)に戻したときの標線間距離を読み取る。その測定値を以下の計算式に代入して、瞬間歪み(%)を算出する。
瞬間歪み(%)=100×ΔL2/L2。
前記L2は、引張る前のサンプル片の標線間距離(mm)を示し、前記ΔL2は、伸張後に荷重を戻したときのサンプル片の標線間距離の増加(mm)を示す。
The measurement is performed by, for example, using a constant crosshead speed type or pendulum type tensile tester (elongation speed at the time of test: 50 mm / min or 6000 mm / min) and applying a predetermined load (N) to the marked line of the sample piece. The distance is increased until the distance becomes a predetermined magnification (1.60 times or 1.75 times), and immediately after this, the distance between the marked lines when the load is returned to 0 (N) is read. By substituting the measured value into the following formula, the instantaneous strain (%) is calculated.
Instantaneous strain (%) = 100 × ΔL2 / L2.
The L2 indicates the distance (mm) between the marked lines of the sample pieces before pulling, and the ΔL2 indicates the increase (mm) in the distance between the marked lines of the sample pieces when the load is returned after stretching.

なお、永久歪み(%)は、前記引張り試験後、試験機から取り外し、23℃の恒温槽で4週間保管した後に上記標線間距離を読み取って算出できる。
以下、引張り試験とは、前記瞬間歪みの測定法における、引張試験機を用いてサンプル片を引き伸ばすことをいう。
The permanent strain (%) can be calculated by removing the distance from the marked line after removing from the testing machine after the tensile test and storing in a thermostatic bath at 23 ° C. for 4 weeks.
Hereinafter, the tensile test refers to stretching a sample piece using a tensile tester in the instantaneous strain measurement method.

また、前記高伸縮タイプの自己伸縮性フィルムのストレッチ特性は、永久歪みによっても表すことができる。永久歪み(%)は、瞬間歪みと同様に、引張り試験後にサンプル片が元の長さに戻らずに変形した度合いを示すが、荷重を取り除いた4週間後に測定する点で瞬間歪みと異なる。永久歪みを測定するときの引張り試験におけるサンプル片の伸張速度は、「50mm/分」である。
永久歪みが小さいほど、ラベルの復元性が高く、ストレッチ特性に優れる。中でも、周方向に伸張倍率1.60倍に伸張後の永久歪み(50mm/分)は、11%以下が好ましく、8%以下がより好ましく、7%以下が特に好ましく、6%以下が最も好ましい。
In addition, the stretch characteristics of the high-stretch type self-stretchable film can be expressed by permanent set. Permanent strain (%) indicates the degree of deformation of the sample piece without returning to its original length after the tensile test, similar to the instantaneous strain, but differs from the instantaneous strain in that it is measured 4 weeks after the load is removed. The extension rate of the sample piece in the tensile test when measuring permanent set is “50 mm / min”.
The smaller the permanent set, the higher the recoverability of the label and the better the stretch characteristics. Among them, the permanent set (50 mm / min) after stretching at a stretching magnification of 1.60 times in the circumferential direction is preferably 11% or less, more preferably 8% or less, particularly preferably 7% or less, and most preferably 6% or less. .

また、印刷層を位置ずれなく形成するためには、縦方向の引張り応力が4.3N/mmであるときの、自己伸縮性フィルムの縦方向の伸び(50mm/分)が、9%以下(例えば、1%〜9%)であることが好ましく、4%〜9%であることがより好ましく、5%〜8%が特に好ましい。
前記縦方向の伸びは、引張り応力と伸び(歪み)との応力歪み曲線から求めることができる。
Further, in order to form the printed layer without displacement, the longitudinal elongation (50 mm / min) of the self-stretchable film when the longitudinal tensile stress is 4.3 N / mm 2 is 9% or less. (For example, 1% to 9%) is preferable, 4% to 9% is more preferable, and 5% to 8% is particularly preferable.
The elongation in the longitudinal direction can be obtained from a stress strain curve of tensile stress and elongation (strain).

具体的には、自己伸縮性フィルムを、他方向(筒状体の縦方向に相当)に長さ200mm(標線間距離100±2mm)、一方向(筒状体の周方向に相当)に長さ15±0.1mmの長方形に切り取り、サンプル片を作製する。このサンプル片の長辺方向(ストレッチラベルの縦方向)を測定方向として、クロスヘッド速度一定型又は振子型引張試験機(伸張速度:50mm/分)を用いて、サンプル片を引張り、そのときの応力歪み曲線を得る。その曲線から求められる、引張り応力4.3N/mmのときのサンプル片の伸び(%)を、前記縦方向の伸びとする。 Specifically, the self-stretchable film has a length of 200 mm in the other direction (corresponding to the longitudinal direction of the cylindrical body) (distance between the marked lines 100 ± 2 mm) and one direction (corresponding to the circumferential direction of the cylindrical body). Cut into a rectangle of length 15 ± 0.1 mm to make a sample piece. Using the long side direction (longitudinal direction of the stretch label) of this sample piece as the measurement direction, the sample piece is pulled using a constant crosshead speed type or pendulum type tensile tester (extension speed: 50 mm / min). Obtain a stress strain curve. The elongation (%) of the sample piece when the tensile stress is 4.3 N / mm 2 obtained from the curve is defined as the elongation in the longitudinal direction.

また、前記自己伸縮性フィルムは、筒状体としたときに、少なくとも周方向に対して伸張倍率1.10倍に伸張させたときの引張り応力(以下、F10値とする)が、好ましくは1〜10N/mm、より好ましくは2〜8N/mm、特に好ましくは3〜7N/mmである。
また、前記少なくとも周方向に対して伸張倍率1.60倍に伸張させたときの引張り応力(以下、F60値とする)は、好ましくは1〜12N/mm、より好ましくは2〜10N/mm、特に好ましくは3〜9N/mmである。なお、F10値及びF60値の下限値が低すぎると伸張した状態で容器の締め付け力が弱くなりすぎ、見栄えの良い装着状態が得られない場合がある。
前記F10値及びF60値は、前記瞬間歪みの測定法の引張り試験により得られる、引張り応力と伸び(歪み)との応力歪み曲線から求めることができる。
Further, when the self-stretchable film is a cylindrical body, the tensile stress (hereinafter referred to as F10 value) when stretched at least 1.10 times in the circumferential direction is preferably 1. 10 N / mm 2 , more preferably 2 to 8 N / mm 2 , and particularly preferably 3 to 7 N / mm 2 .
Moreover, the tensile stress (hereinafter referred to as F60 value) when stretched at least 1.60 times with respect to the circumferential direction is preferably 1 to 12 N / mm 2 , more preferably 2 to 10 N / mm. 2 , particularly preferably 3 to 9 N / mm 2 . In addition, if the lower limit value of the F10 value and the F60 value is too low, the tightening force of the container becomes too weak in the stretched state, and a good-looking wearing state may not be obtained.
The F10 value and F60 value can be determined from a stress strain curve of tensile stress and elongation (strain) obtained by a tensile test of the instantaneous strain measurement method.

上記のように、周方向の伸張倍率が1.60倍以上と高く、且つ周方向に1.60倍に伸張後の瞬間歪み(50mm/分)が13%以下、周方向のF10値が10N/mm以下といういずれも小さな値を示す高伸縮タイプの自己伸縮性フィルムを用いた場合には、その筒状体は、従来のストレッチラベルにはない優れたストレッチ特性を有している。さらに、かかる筒状体は、優れたストレッチ特性を有しながら、上記のように、良好な製造適性を有する。 As described above, the expansion ratio in the circumferential direction is as high as 1.60 times or more, the instantaneous strain (50 mm / min) after expansion to 1.60 times in the circumferential direction is 13% or less, and the F10 value in the circumferential direction is 10 N.

本発明のストレッチラベル1は、拡張力を加えることによって拡径させ、その状態で容器などの被着体の所定位置に嵌挿し、その後、拡張力を解除することによって被着体に装着できる。
1.25倍程度に伸張可能なストレッチラベル1は、装着箇所に径差のある部分を有する被着体への装着には適さないが、装着箇所に実質的に径差がない被着体への装着には適している。
The stretch label 1 of the present invention can be attached to the adherend by expanding the diameter by applying an expansion force, inserting the stretch label 1 into a predetermined position of the adherend such as a container in that state, and then releasing the expansion force.
1. Stretch label 1 that can be stretched about 1.25 times is not suitable for attachment to an adherend having a portion with a diameter difference at the attachment location, but to an adherend that has no substantial difference in diameter at the attachment location. Suitable for mounting.

中でも、上記高伸縮タイプの自己伸縮性フィルムから形成されたストレッチラベル1は、特に、径差の大きい部分を有する被着体への装着に好適である。
径差の大きい部分を有する被着体としては、代表的には、飲料容器、調味料容器、シャンプーなどのサニタリー容器、洗剤容器、化粧品容器、医薬品容器などの各種容器が代表的に挙げられる。
Among these, the stretch label 1 formed from the high-stretch type self-stretch film is particularly suitable for mounting on an adherend having a portion having a large diameter difference.
Representative examples of the adherend having a large diameter difference include sanitary containers such as beverage containers, seasoning containers, and shampoos, detergent containers, cosmetic containers, and pharmaceutical containers.

図5に示す容器7は、径差の大きい部分を有する容器(例えば、飲料容器)であり、胴部71と、胴部71の上方に設けられ且つ上方に向かって次第に縮径して窄んでいく肩部72と、肩部72の上方に設けられたキャップ73と、胴部71の下方に設けられ且つ下方に向かって次第に縮径して窄んでいくアール部74と、アール部74の下方に設けられた底面部75と、を有する。前記肩部72は、胴部の上方に連設され且つ上方に向かって次第に縮径する上方の縮径部に相当し、前記アール部74は、胴部の下方に連設され且つ下方に向かって次第に縮径する下方の縮径部に相当する。
この容器7の胴部71の縦方向中間部には、周方向に窪んだ凹部が周設されている。従って、この凹部は、胴部71の小径部711に相当し、その凹部の上下には、胴部71の大径部712がある。ストレッチラベル1は、前記肩部72と胴部71の大径部712、又は、胴部71の小径部711と大径部712の少なくとも何れかに跨って装着できる。
A container 7 shown in FIG. 5 is a container (for example, a beverage container) having a large diameter difference. The container 7 is provided above the body 71 and the body 71 and is gradually reduced in diameter and constricted. A shoulder portion 72, a cap 73 provided above the shoulder portion 72, a round portion 74 provided below the trunk portion 71 and gradually reducing its diameter toward the bottom, and a lower portion of the round portion 74. And a bottom surface portion 75 provided on the surface. The shoulder portion 72 is connected to the upper portion of the trunk portion and corresponds to an upper reduced diameter portion that gradually decreases in diameter upward, and the rounded portion 74 is connected to the lower portion of the trunk portion and faces downward. This corresponds to a lower diameter-reduced portion that gradually decreases in diameter.
A concave portion that is recessed in the circumferential direction is provided in the middle in the longitudinal direction of the body 71 of the container 7. Therefore, the concave portion corresponds to the small diameter portion 711 of the trunk portion 71, and the large diameter portion 712 of the trunk portion 71 is above and below the concave portion. The stretch label 1 can be mounted across at least one of the shoulder portion 72 and the large diameter portion 712 of the body portion 71 or the small diameter portion 711 and the large diameter portion 712 of the body portion 71.

上記ストレッチラベル1の内径は、装着箇所のうち最も小さい外径よりも小さくなるように設計されている。厳密には、瞬間歪みを考慮して、伸張させ且つ伸張解除後の内径が前記装着箇所の最小外径よりも小さくなるように、ストレッチラベル1の周長が予め設計されている。   The inner diameter of the stretch label 1 is designed to be smaller than the smallest outer diameter of the mounting locations. Strictly speaking, in consideration of instantaneous strain, the circumference of the stretch label 1 is designed in advance so that the inner diameter after extension and release of extension becomes smaller than the minimum outer diameter of the mounting portion.

ストレッチラベル1を前記容器7に装着する際には、ストレッチャーなどの治具をストレッチラベル1の内側に入れ、治具にてストレッチラベル1の全体を、胴部71の大径部712の外径よりも大きくなるまで拡径する。その状態で、ストレッチラベル1を容器7の上方から胴部71にまで治具と共に嵌挿し、治具を引き抜くと、ストレッチラベル1が復元して、胴部71の大径部712、小径部711及び肩部72に密着する。
なお、胴部71の上方に前記小径な肩部72を有する容器7にあっては、ストレッチラベル1の全体を拡径せず、ストレッチラベル1の中間部及び下方部のみを治具で拡径し(つまり、装着後に肩部72に対応するストレッチラベル1の上方部は拡径せず、その上方部以外のみを拡径し)、容器7の上方から胴部71に嵌挿することもできる。このようにストレッチラベル1の上方部以外を拡径して装着する装着方法は、特開平6−259015に開示されているので、その具体的な手順はそれを参照されたい。
When the stretch label 1 is attached to the container 7, a jig such as a stretcher is placed inside the stretch label 1, and the entire stretch label 1 is placed outside the large-diameter portion 712 of the trunk portion 71 with the jig. The diameter is expanded until it becomes larger than the diameter. In that state, when the stretch label 1 is inserted and inserted together with the jig from the upper side of the container 7 to the body portion 71 and the jig is pulled out, the stretch label 1 is restored, and the large diameter portion 712 and the small diameter portion 711 of the body portion 71 are restored. And the shoulder 72 are in close contact with each other.
In the container 7 having the small-diameter shoulder portion 72 above the body portion 71, the diameter of the entire stretch label 1 is not expanded, and only the middle portion and the lower portion of the stretch label 1 are expanded with a jig. (In other words, the diameter of the upper part of the stretch label 1 corresponding to the shoulder 72 after mounting is not increased, and only the diameter other than the upper part is expanded), and can be inserted into the body 71 from above the container 7. . A mounting method for expanding and mounting the portion other than the upper portion of the stretch label 1 is disclosed in Japanese Patent Laid-Open No. 6-259015. Refer to it for the specific procedure.

このようにして、容器7などの被着体にストレッチラベル1が装着された包装体10が得られる(図6に示すようなラベル付き容器)。ストレッチラベル1は、高摩擦面2Hが容器7の少なくとも肩部72に対応するように装着されている。
なお、包装体10において、ストレッチラベル1は、補助ミシン目線6の貫通孔の全部又はその一部(筒状体の上端部に形成された補助ミシン目線6の一部)が前記容器7の肩部52に対応するように、ストレッチラベル1が容器7の胴部71の全部又は一部及び肩部72の全部又は一部を含んで装着されている。
また、ストレッチラベル1の裏面(被着体への接触面)のうち、少なくとも分断用ミシン目線3及びその周辺は、被着体に接着されておらず、好ましくは、ストレッチラベル1の裏面全体は、被着体に接着されていない。
本発明のストレッチラベル1は、分断用ミシン目線3が形成されているが、その貫通孔及び非貫通部の長さが上記範囲であるので、拡径時に隣接する貫通孔が繋がって穴を生じることはない。また、分断用ミシン目線3についても同様に、ストレッチラベル1の拡径時に、隣接する貫通孔が繋がることもない。
In this way, a package 10 in which the stretch label 1 is attached to an adherend such as the container 7 is obtained (a container with a label as shown in FIG. 6). The stretch label 1 is mounted such that the high friction surface 2H corresponds to at least the shoulder 72 of the container 7.
In the package 10, the stretch label 1 has the whole perforation hole of the auxiliary perforation line 6 or a part thereof (a part of the auxiliary perforation line 6 formed at the upper end portion of the cylindrical body) of the shoulder of the container 7. The stretch label 1 is attached so as to correspond to the part 52 including all or part of the trunk part 71 of the container 7 and all or part of the shoulder part 72.
Further, among the back surface of the stretch label 1 (contact surface to the adherend), at least the perforation line 3 for cutting and the periphery thereof are not adhered to the adherend, and preferably the entire back surface of the stretch label 1 is It is not adhered to the adherend.
In the stretch label 1 of the present invention, the perforation line 3 for cutting is formed, but since the lengths of the through hole and the non-penetrating portion are in the above range, adjacent through holes are connected at the time of diameter expansion to form a hole. There is nothing. Similarly, when the stretch label 1 is expanded in diameter, the adjacent perforations are not connected to the perforating line 3 for dividing.

上記包装体10について、ストレッチラベル1と被着体を分別する際には、分断用ミシン目線3を利用してストレッチラベル1を縦方向に分断する。
この際、分断用ミシン目線3を基準にして、その周方向一方側又は周方向他方側におけるストレッチラベル1の表面に指先を当てる。好ましくは、分断用ミシン目線3を基準にして、その周方向一方側及び周方向他方側におけるストレッチラベル1の表面に指先をそれぞれ当てる。より好ましくは、図6の二点鎖線で示すように、補助ミシン目線6が設けられた筒状体2の上方部に指先を当て、特に好ましくは、高摩擦面2Hの上に指先を当てることにより、指先が滑り難くなる。
About the said package 10, when separating the stretch label 1 and a to-be-adhered body, the stretch label 1 is partly divided | segmented using the perforation line 3 for a parting.
At this time, the fingertip is applied to the surface of the stretch label 1 on one side in the circumferential direction or the other side in the circumferential direction with reference to the perforation line 3 for cutting. Preferably, the fingertips are respectively applied to the surface of the stretch label 1 on one side in the circumferential direction and the other side in the circumferential direction with reference to the perforation line 3 for cutting. More preferably, as shown by a two-dot chain line in FIG. 6, the fingertip is applied to the upper portion of the cylindrical body 2 provided with the auxiliary perforation line 6, and particularly preferably, the fingertip is applied to the high friction surface 2H. This makes it difficult for the fingertips to slip.

そして、指先にてストレッチラベル1の表面から被着体側にストレッチラベル1を押圧し、両指先が互いに離反するように(分断用ミシン目線3から互いに離反するように)、両指先を周方向一方側及び他方側にそれぞれスライドさせる。なお、片方の指だけを当てた場合には、その指先が分断用ミシン目線3から離れる方向にスライドさせる。
すると、ストレッチラベル1には互い離反する方向に引裂き力が加わり、それが分断用ミシン目線3の貫通孔の縁に集中するので、分断用ミシン目線3に沿って裂け目が生じ、ストレッチラベル1を分断できる。
And the stretch label 1 is pressed to the adherend side from the surface of the stretch label 1 with the fingertips, and both the fingertips are moved in the circumferential direction so that the two fingertips are separated from each other (so as to be separated from the perforation line 3 for cutting). Slide to the side and the other side respectively. When only one finger is applied, the fingertip is slid in a direction away from the dividing perforation line 3.
Then, a tearing force is applied to the stretch label 1 in a direction away from each other, which concentrates on the edge of the through hole of the dividing perforation line 3, so that a tear is generated along the dividing perforation line 3, and the stretch label 1 is removed. Can be divided.

特に、本実施形態では、補助ミシン目線6が筒状体2の上端部から設けられているので、前記引裂き力が加わったときに、補助ミシン目線6の貫通孔の縁にも集中するので、筒状体2の上端部にある補助ミシン目線6の貫通孔から裂け目が生じやすい。この補助ミシン目線6の裂け目が分断用ミシン目線3に伝わって、分断用ミシン目線3に沿ってストレッチラベル1を分断し易くなる。
また、高摩擦面2Hが形成されているので、指先が滑り難く、指をスライドさせることにより、ストレッチラベル1に引裂き力を確実に作用させて分断用ミシン目線3から分断できる。
In particular, in the present embodiment, since the auxiliary perforation line 6 is provided from the upper end portion of the cylindrical body 2, when the tearing force is applied, the auxiliary perforation line 6 also concentrates on the edge of the through hole of the auxiliary perforation line 6. A tear is likely to occur from the through hole of the auxiliary perforation line 6 at the upper end of the cylindrical body 2. The split of the auxiliary perforation line 6 is transmitted to the cutting perforation line 3 and the stretch label 1 can be easily cut along the cutting perforation line 3.
In addition, since the high friction surface 2H is formed, the fingertip is difficult to slip, and by sliding the finger, the tearing force can be applied to the stretch label 1 with certainty, so that it can be divided from the dividing perforation line 3.

なお、本発明は、上記実施形態に限られず、本発明の意図する範囲で様々に変更できる。
例えば、上記実施形態において、補助ミシン目線6は、筒状体2の上端部から形成されているが、図7に示すように、補助ミシン目線6は、筒状体2の下端部から分断用ミシン目線3の中途部にまで設けられていてもよいし、或いは、特に図示しないが、筒状体2の上端部及び下端部の双方にそれぞれ設けられていてもよい。
補助ミシン目線6を筒状体2の下端部に設ける場合の具体例は、上記実施形態の上端部に補助ミシン目線6を設ける場合と同様である(つまり、上下反対に考えればよい)。補助ミシン目線6を下端部に設ける場合には、それに対応して、高摩擦面2Hも筒状体2の下方部に設けることが好ましい。
補助ミシン目線6を筒状体2の下端部に設けた場合、装着されたストレッチラベル1を分断する際には、その下方部に指先を当てて分断用ミシン目線3に引裂き力を加えればよい。
なお、補助ミシン目線6を筒状体2の上端部及び下端部の双方に設ける場合には、高摩擦面2Hもそれらに対応してそれぞれの両側に設けることが好ましい。
In addition, this invention is not restricted to the said embodiment, In the range which this invention intends, it can change variously.
For example, in the above embodiment, the auxiliary perforation line 6 is formed from the upper end portion of the cylindrical body 2, but the auxiliary perforation line 6 is for cutting from the lower end portion of the cylindrical body 2 as shown in FIG. 7. It may be provided up to the middle part of the perforation line 3, or may be provided at both the upper end part and the lower end part of the cylindrical body 2, although not particularly illustrated.
A specific example in the case where the auxiliary perforation line 6 is provided at the lower end portion of the cylindrical body 2 is the same as the case where the auxiliary perforation line 6 is provided at the upper end portion of the above-described embodiment (that is, it may be considered upside down). When the auxiliary perforation line 6 is provided at the lower end, it is preferable that the high friction surface 2H is also provided at the lower part of the cylindrical body 2 correspondingly.
When the auxiliary perforation line 6 is provided at the lower end portion of the cylindrical body 2, when the attached stretch label 1 is cut, a tearing force may be applied to the cutting perforation line 3 by applying a fingertip to the lower part thereof. .
In addition, when providing the auxiliary perforation line 6 in both the upper end part and lower end part of the cylindrical body 2, it is preferable to also provide the high friction surface 2H on each both sides corresponding to them.

補助ミシン目線6が筒状体2の下端部に設けられたストレッチラベル1は、好ましくは、ストレッチラベル1の補助ミシン目線6の全部又は一部(筒状体の下端部に形成された補助ミシン目線6の一部)が容器7のアール部74に対応するように、容器7に装着される(図示せず)。
この場合、ストレッチラベル1は、容器7の肩部72の全部又は一部、胴部71の全部、アール部74の全部又は一部を含むように、容器7に装着されていることが好ましい。
The stretch label 1 in which the auxiliary perforation line 6 is provided at the lower end of the cylindrical body 2 is preferably all or a part of the auxiliary perforation line 6 of the stretch label 1 (the auxiliary perforation formed at the lower end of the cylindrical body). The container 7 is mounted (not shown) so that a part of the line of sight 6 corresponds to the rounded portion 74 of the container 7.
In this case, the stretch label 1 is preferably attached to the container 7 so as to include all or part of the shoulder 72 of the container 7, all of the trunk 71, and all or part of the rounded part 74.

また、上記実施形態では、補助ミシン目線6は、筒状体2の上端部(又は下端部)から1本だけ形成されているが、例えば、図8に示すように、筒状体2の上端部(又は下端部)から分断用ミシン目線3の縦方向中途部又はその近傍にまで設けられた補助ミシン目線6が、複数(好ましくは2本)形成されていてもよい。この場合、上記本発明の分断方法によってストレッチラベル1を分断し易くなることから、第1補助ミシン目線61は、分断用ミシン目線3を基準にして周方向一方側に設けられ、且つ、第2補助ミシン目線62は、分断用ミシン目線3を基準にして周方向他方側に設けられていることが好ましい。   In the above embodiment, only one auxiliary perforation line 6 is formed from the upper end (or lower end) of the cylindrical body 2. For example, as shown in FIG. A plurality (preferably two) of auxiliary perforation lines 6 provided from the part (or the lower end part) to the middle part in the longitudinal direction of the dividing perforation line 3 or in the vicinity thereof may be formed. In this case, since the stretch label 1 can be easily cut by the cutting method of the present invention, the first auxiliary perforation line 61 is provided on one side in the circumferential direction with respect to the cutting perforation line 3, and the second The auxiliary perforation line 62 is preferably provided on the other side in the circumferential direction with respect to the dividing perforation line 3.

さらに、上記実施形態では、補助ミシン目線6の各貫通孔は、筒状体2の周方向及び縦方向に傾斜する方向に延びているが、例えば、図9に示すように、筒状体2の縦方向に平行に延びて形成されていてもよい。
貫通孔自体が縦方向に延びる補助ミシン目線6であっても、各貫通孔は、上記実施形態と同様に、縦方向において部分的に重ならずに位置ずれしており、補助ミシン目線6を全体として見れば、筒状体2の周方向に対して斜めに延びている。
Furthermore, in the said embodiment, although each through-hole of the auxiliary perforation line 6 is extended in the direction inclined in the circumferential direction and the vertical direction of the cylindrical body 2, for example, as shown in FIG. It may be formed extending in parallel with the vertical direction.
Even if the through hole itself is the auxiliary perforation line 6 extending in the vertical direction, each through hole is displaced in the vertical direction without being partially overlapped as in the above embodiment. When viewed as a whole, it extends obliquely with respect to the circumferential direction of the cylindrical body 2.

さらに、上記実施形態のストレッチラベル1は、補助ミシン目線6が設けられているが、例えば、図10に示すように、補助ミシン目線が形成されていなくてもよい。
この場合、上記実施形態と同様に、分断用ミシン目線3の、周方向一方側及び周方向他方側の少なくとも何れか一方における筒状体2の表面に、高摩擦面(図10において図示せず)が設けられていることにより、上記本発明の分断方法によってストレッチラベル1を分断し易くなる。
Furthermore, although the auxiliary perforation line 6 is provided in the stretch label 1 of the said embodiment, as shown in FIG. 10, the auxiliary perforation line does not need to be formed, for example.
In this case, as in the above embodiment, a high friction surface (not shown in FIG. 10) is formed on the surface of the cylindrical body 2 on at least one of the circumferential one side and the other circumferential side of the dividing perforation line 3. ) Is provided, the stretch label 1 can be easily cut by the cutting method of the present invention.

また、上記実施形態のストレッチラベル1は、高摩擦面と低摩擦面とが設けられているが、筒状体2の表面全体を上記静摩擦係数を有する高摩擦面のみから構成してもよいし、筒状体2の表面に高摩擦面が設けられていなくてもよい。

[Production of self-stretchable film (A)]
A linear low density polyethylene (manufactured by Ube Maruzen Polyethylene Co., Ltd., trade name “Umerit 715FT”) and erucic acid amide (manufactured by Ube Maruzen Polyethylene Co., Ltd., trade name “M405”) as a slip agent are 0 for the total amount The resin composition was prepared by adding 0.8 mass% of synthetic zeolite (manufactured by Ube Maruzen Polyethylene Co., Ltd., trade name “24201M”) as an antiblocking agent to 0.8 mass% of the total amount. The resin composition is melted at 210 ° C. using an extruder of a feed block type 2 layer 3 layer type, and this is extruded from a slot of a T die onto a 25 ° C. casting drum to rapidly cool and solidify. A three-layer unstretched film was produced.
This unstretched film was stretched 1.06 times in the MD direction at a stretching temperature of 52 ° C., and then stretched 1.06 times in the TD direction at a stretching temperature of 82 ° C., thereby forming a biaxially stretched film having a thickness of 50 μm ( A self-stretchable film (A)) was produced. In addition, extending | stretching was performed by the tenter system.

As a result, the refractive index in the MD direction of the biaxially stretched film was 1.515, the refractive index in the TD direction was 1.513, and the refractive index in the thickness direction was 1.508.

前記二軸延伸フィルムの1.60倍伸張後の瞬間歪み、引張り応力4.3N/mmのときの伸び、F10値及びF60値を測定した。
その結果、伸張速度50mm/分での1.60倍伸張後の瞬間歪みは、9.8%、伸張速度6000mm/分での1.60倍伸張後の瞬間歪みは、3.5%、引張り応力4.3N/mmのときの伸びは、6.8%、F10値は、5.2N/mm、F60値は、7.5N/mmであった。
The biaxially stretched film was measured for instantaneous strain after stretching 1.60 times, elongation at a tensile stress of 4.3 N / mm 2 , F10 value and F60 value.
As a result, the instantaneous strain after stretching 1.60 times at a stretching speed of 50 mm / min is 9.8%, the instantaneous strain after stretching 1.60 times at a stretching speed of 6000 mm / min is 3.5%, The elongation at a stress of 4.3 N / mm 2 was 6.8%, the F10 value was 5.2 N / mm 2 , and the F60 value was 7.5 N / mm 2 .

1.60倍伸張後の瞬間歪み、F10値(1.10倍に伸張させたときの引張り応力)及びF60値(1.60倍に伸張させたときの引張り応力)は、次のようにして測定した。
二軸延伸フィルムを、MD方向に長さ15±0.1mm、TD方向に長さ200mm(標線間距離100±2mm)の長方形に切り取り、第1サンプル片を作製した。この第1サンプル片のTD方向を測定方向として、1.60倍になるまで引張り、第1サンプル片の標線間距離を計測した。なお、後述するように、二軸延伸フィルムのTD方向は、ストレッチラベルの周方向に対応し、MD方向は、縦方向に対応する。

The biaxially stretched film was cut into a rectangle having a length of 15 ± 0.1 mm in the MD direction and a length of 200 mm in the TD direction (distance between marked lines 100 ± 2 mm) to produce a first sample piece. Using the TD direction of the first sample piece as a measurement direction, the first sample piece was pulled to 1.60 times, and the distance between the marked lines of the first sample piece was measured. As will be described later, the TD direction of the biaxially stretched film corresponds to the circumferential direction of the stretch label, and the MD direction corresponds to the longitudinal direction.

次に、クロスヘッド速度一定型又は振子型引張試験機を用いて、第1サンプル片の標線間距離が前記1.60倍に引張ったときに計測した標線間距離になるまで、伸張速度50mm/分で伸ばし、その直後に荷重を0(N)に戻したときの引張り応力と伸び(歪み)とからなる応力歪み曲線からF10値及びF60値を求めた。同時に、前記荷重を0(N)に戻したときの標線間距離を計測し、式:瞬間歪み(%)=100×(伸張後に荷重を戻したときの第1サンプル片の標線間距離の増加(mm)/引張る前の第1サンプル片の標線間距離(mm))、に従って伸張速度50mm/分での1.60倍伸張後の瞬間歪みを算出した。
伸張速度6000mm/分での1.60倍伸張後の瞬間歪みは、伸張速度6000mm/分としたこと以外は、上記と同様にして測定し、算出した。
Next, using a crosshead speed constant type or pendulum type tensile tester, the extension speed until the distance between the marked lines of the first sample piece becomes the distance between the marked lines measured when it is pulled 1.60 times. F10 and F60 values were determined from a stress-strain curve consisting of tensile stress and elongation (strain) when the load was returned to 0 (N) immediately after stretching at 50 mm / min. At the same time, the distance between the marked lines when the load is returned to 0 (N) is measured, and the formula: instantaneous strain (%) = 100 × (distance between the marked lines of the first sample piece when the load is returned after stretching. The instantaneous strain after stretching 1.60 times at a stretching speed of 50 mm / min was calculated according to the following (Increase in mm) / Distance between marked lines of the first sample piece before pulling (mm)).
The instantaneous strain after 1.60 times stretching at a stretching speed of 6000 mm / min was measured and calculated in the same manner as above except that the stretching speed was 6000 mm / min.
