Description

The present invention relates to a closed label, a lid and a package.

There is a technique for forming an outlet by peeling off a label attached to an area where an outlet is to be formed in order to take out the contained from the package containing the contained (see Patent Document 1). In such a package, the outlet can be resealed by reattaching the label.

Japanese Unexamined Patent Publication No. 10-24972

If the outlet can be opened and resealed by peeling and reattaching the label, for example, if the package is placed on the product shelf as a product, the product is purchased for the purpose of mischief, confirmation of the contained contents, etc. The label may be peeled off before. In this case, the contents in the package from which the label has been peeled off cannot be sold as a commercial product.

An object of one aspect of the present invention is to provide a reclosed label, a lid and a package that can be reliably confirmed to be in an unopened state.

The reclosed label according to one aspect of the present invention is a reclosed label that can be attached to a support member on which an outlet for taking out an inclusion is formed, and the outlet can be opened and resealed. It includes a knob that serves as a starting point for opening, and a label body that is adjacent to the knob in the opening direction. The label body indicates that the outlet is in an unopened state near the knob. The unopened revealing portion has an unopened revealing portion, and the unopened revealing portion has a breaking induction line that induces breakage of the label body in response to peeling when opening from the unopened state of the outlet, and the above-mentioned in the opening direction. It is arranged on the opposite side of the knob from the break induction line, and has a break stop line for stopping the break, and the break inducement line and the break stop line are each with respect to the opening direction. The inner end of the rupture-inducing line is located at the same position as the inner end of the rupture stop line or outside the inner end of the rupture stop line when viewed from the opening direction. The outer end of the rupture inducing line is separated from the rupture stop line, and the outer end of the rupture inducing line is the outer end of the rupture stop line when viewed from the opening direction. It is located more inside.

When the reclose label is attached to the support member and peeled off from the knob to open the outlet, when the breakage trigger line of the unopened revealing part is peeled off, the label body is peeled off by the breakage trigger line. Is induced to break. When viewed from the opening direction, the inner end portion of the rupture induction line is located at the same position as the inner end portion of the rupture stop line or outside the inner end portion of the rupture stop line. When viewed from the opening direction, the outer end portion of the break induction line is located inside the outer end portion of the break stop line. Therefore, the rupture induced by the rupture trigger line is received and stopped at the rupture stop line. The rupture induced by the rupture-inducing line remains on the reclose label even if the reclose label is reattached to the support member in order to reseal the outlet. That is, in the closed label, the unopened state of the outlet can be reliably confirmed by the presence or absence of the break mark. In other words, if no trace of breakage can be confirmed in the unopened revealing portion, it indicates that the product has not been opened.

When the label body is viewed in a plan view, the inner end portion of the breakage trigger line may overlap with the inner end portion of the breakage stop line. In this case, the rupture is induced at the position of the outer end portion in the rupture induction line.

The break induction line and the break stop line are cut lines, and the outer end portion of the break stop line is located on the opposite side of the knob portion in the opening direction from the inner end portion of the break stop line. You may be. In this case, as described above, when a rupture occurs from the rupture inducing line, the portion between the rupture inducing line and the rupture stop line where the rupture inducing line and the rupture stop line overlap when viewed from the opening direction is the label body. Separated from. Due to the positional relationship between the outer end and the inner end of the rupture stop line, the rupture originating from the rupture induction line and received at the rupture stop line propagates outward.

The label body is arranged on the opposite side of the knob from the break stop line, and the first break guide portion that guides the break of the label body generated from the outer end of the break stop line in the outward direction. May have. In this case, even if the label body breaks from the outer end of the break stop line, the break is surely induced in the outward direction at the first break guide portion. Therefore, it is possible to prevent the reclosed label (specifically, the label body) from breaking toward the inside, so that the reclosed label (specifically, the label body) is damaged so that the outlet cannot be resealed, for example. Can be prevented.

The first break guide portion has a plurality of break guide lines that are non-parallel to the opening direction, and the plurality of break guide lines are arranged apart from each other along the opening direction, and the opening is performed. Of the two rupture guide lines adjacent to each other in the direction, the rupture guide wire on the knob side is referred to as the first rupture guide wire, and the rupture guide wire opposite to the crushed portion is the second rupture guide wire with respect to the first rupture guide wire. When referred to as a guide wire, the outer portion of the first break guide wire and the inner portion of the second break guide wire may overlap when viewed from the opening direction. In this case, the breakage of the label body generated from the outer end portion of the breakage stop line can be sequentially propagated to a plurality of breakage guide lines and guided outward.

The fracture stop line and the plurality of fracture guide lines are straight lines parallel to each other, and the arrangement relationship of the plurality of fracture guide lines is the outer portion of the first fracture guide line when viewed from the second fracture guide line. And the distance between the first break guide line and the second break guide line in the overlapping region with the inner portion of the second break guide line, and the length in the direction parallel to the second break guide line in the overlap region. Each of them satisfies the arrangement condition that the length of the second fracture guide line is 1/10 to 1/3, the fracture stop line is regarded as the first fracture guide line, and the plurality of fracture guide lines are regarded as the first fracture guide lines. When the break guide line on the side of the break stop line is regarded as the second break guide line, the arrangement relationship between the break stop line and the first break guide line may satisfy the above arrangement condition.
As a result, the breakage of the label body generated from the outer end portion of the breakage stop line can be more reliably guided outward.

The label main body is arranged near the end opposite to the knob portion, and the label main body is broken at the side edge portion so as to break a part of the label main body from the side edge portion of the label main body. It may have a second fracture guiding portion that guides toward the inside of the.
May be good.

In this case, when the reclose label is attached to the support member and then the reclose label is peeled off from the knob to open the outlet, the label body is peeled off to the second breakage guiding portion. A part of the label body breaks from the side edge to the inside. The broken portion is not easily affected by the portion of the reclose label that is not peeled off and is attached to the support member. Therefore, the peeled portion of the reclosed label is prevented from returning to its original position (moving in the direction of resealing the outlet).

The lid according to the other aspect of the present invention is attached to a support member having a notch forming a cut portion that defines a planned outlet portion to be an outlet for taking out the contained matter, and the support member. The reclose label is provided with the reclose label, and the reclose label is attached to the support member so that the notch portion is covered by the label main body, and the unopened revealing portion is the cut in the label main body. It may be formed between the region corresponding to the recess and the knob.

In the above lid, when the label is peeled off from the knob to open the outlet, the label body is ruptured by the rupture-inducing line when the rupture-inducing line of the unopened revealing portion is peeled off. When viewed from the opening direction, the inner end portion of the rupture induction line is located at the same position as the inner end portion of the rupture stop line or outside the inner end portion of the rupture stop line. When viewed from the opening direction, the outer end portion of the break induction line is located inside the outer end portion of the break stop line. Therefore, the rupture induced by the rupture trigger line is received and stopped at the rupture stop line. The rupture induced by the rupture-inducing line remains on the reclose label even if the reclose label is reattached to the support member in order to reseal the outlet. That is, in the lid body, the unopened state of the outlet can be reliably confirmed by the presence or absence of the break mark. In other words, if no trace of breakage can be confirmed in the unopened revealing portion, it indicates that the product has not been opened.

The cut portion may be configured to suppress the return of the reclose label when the reclose label is peeled off and the outlet is opened. As a result, it is possible to prevent the reclose label from automatically returning to block the outlet when the outlet is opened. As a result, it is easy to take out the contents from the take-out port.

The package according to still another aspect of the present invention includes the reclose label or the lid.

According to one aspect of the present invention, it is possible to provide a reclosed label, a lid and a package that can be surely confirmed to be in an unopened state.

(First Embodiment)
FIG. 1 is a perspective view of a package having a reclosed label according to an embodiment. FIG. 2 is a cross-sectional view taken along the line II-II of FIG. As shown in FIGS. 1 and 2, the package 1 includes a storage container 3 for storing the container 2 and a lid 4 for closing the opening of the storage container 3. Examples of containment 2 are food, wet wipes, cosmetics and the like. Although FIG. 2 illustrates the sheet-shaped container 2, the shape of the container 2 is not limited to the sheet shape.

The storage container 3 includes a bottom wall 5 and a storage portion 7 having a side peripheral wall 6 provided around the bottom wall 5, and a flange portion 8 protruding outward from an end portion of the side peripheral wall 6 opposite to the bottom wall 5. Has. In the present embodiment, the plan view shape of the bottom wall 5 and the plan view shape of the storage container 3 corresponding thereto are rectangular as shown in FIG. However, the plan view shape of the storage container 3 may be circular, elliptical, polygonal, or the like. The material of the storage container 3 may be any material that can be joined to the lid 4 and can appropriately store the container 2. The storage container 3 is made of, for example, plastic.

The lid 4 is a member in which the reclose label 20 is laminated on the base film (support member) 10. The base film 10 is joined to the flange portion 8 so as to close the opening of the storage container 3. The reclose label 20 is attached to the base film 10 so that the package 1 can be opened and resealed.

When the container 2 is taken out from the package 1, the package 1 is reclosed along the opening direction D1 preset (for example, displayed by printing) in the package 1 while lifting the knob 21 of the reclose label 20. The label 20 is peeled off. As a result, as shown in FIG. 3, an outlet 11 for taking out the contained material 2 from the package 1 is formed in the base film 10. Specifically, as the reclose label 20 is peeled off, the region of the base film 10 that becomes the outlet 11 is caused as the film piece 12 on the reclose label 20 side, so that the outlet 11 is formed.

In the present embodiment, in the opening direction D1, the end side of the reclose label 20 and the film piece 12 opposite to the opening end is maintained in a bonded state with the base film 10. Since the reclose label 20 and the connecting portion between the film piece 12 and the base film 10 in the state where the outlet 11 is formed functions as a hinge, the reclose label 20 is reattached to the base film 10 to perform the outlet. 11 can be reliably resealed.

Hereinafter, for convenience of explanation, in the opening direction D1, the side of the picking portion 21 is also referred to as a front side, and the side opposite to the picking portion 21 is also referred to as a rear side.

The lid 4 will be further described with reference to FIG. The lid 4 has a base film 10 and a reclose label 20.

The base film 10 is a film having a sealant layer on the side of the container 3. The plan view shape of the base film 10 may be the same as the plan view shape of the storage container 3. In the present embodiment, the plan view shape of the base film 10 is rectangular. In the present embodiment, the example of the length L1 in the longitudinal direction of the base film 10 is 100 mm to 300 mm, and the example of the length L2 in the lateral direction is 50 mm to 450 mm. In a plan view, the peripheral edge of the base film 10 may protrude outward from the peripheral edge of the storage container 3 (the edge portion of the flange portion 8).

Unless otherwise specified, the examples of various lengths and distances described below are based on the configurations of the base film 10 and the reclose label 20 in the present embodiment (particularly the embodiment shown in FIG. 4).

The base film 10 has a notch portion 13 that defines an outlet scheduled portion 14 that should be the outlet 11. The cut portion 13 exhibits an open ring in which a part of the rear side (the side opposite to the knob portion 21) is open in a plan view. The inside of the cut portion 13 is a planned outlet portion 14 in which the outlet 11 is formed, and is also a portion serving as a film piece 12.

The cut portion 13 includes a first cut line 131 extending in the opening direction D1, a second cut line 132 facing the first cut line 131 and parallel to the first cut line 131, and a first cut line 132. A third cut line 133 connecting the front end of the cut line 131 and the front end of the second cut line 132, and a fourth extending from the rear end of the first cut line 131 to the second cut line 132 side. It has a cut line 134 and a fifth cut line 135 extending from the rear end portion of the second cut line 132 toward the first cut line 131. In the present embodiment, the opening direction D1 is the longitudinal direction of the base film 10 (or the reclose label 20).

The first to fifth cut lines 131 to 135 are lines capable of forming the film piece 12 with the peeling when the reclose label 20 is peeled from the base film 10. The first to fifth cut lines 131 to 135 may be a cut line that fully penetrates in the thickness direction of the base film 10, or may be a cut line that is half-penetrated (half-cut). The first to fifth cut lines 131 to 135 may be continuous cut lines or perforated cut lines (hereinafter, simply referred to as “perforation lines”). The first to fifth cut lines 131 to 135 may be formed by, for example, cutting a blade.

In the present embodiment, the third cut line 133 is curved so as to be convex to the front side. The fourth cut line 134 has a parallel region parallel to the direction orthogonal to the opening direction D1, and is folded back from the end of the parallel region on the second cut line 132 side to the front side. Similarly, the fifth cut line 135 has a parallel region parallel to the direction orthogonal to the opening direction D1, and is folded back from the end of the parallel region on the first cut line 131 side to the front side. The parallel regions of the fourth cut line 134 and the fifth cut line 135 are located on the same straight line and correspond to the rear end portion (or the rear end portion of the outlet 11) of the cut portion 13. The length of the folded portion of the fourth cut line 134 and the fifth cut line 135 is the same. Therefore, the end 134a of the fourth cut line 134 and the end 135a of the fifth cut line 135 are located on the same straight line along the direction orthogonal to the opening direction D1. The end 134a is the end opposite to the rear end of the first cut line 131 in the fourth cut line 134, and the end 135a is the end of the second cut line 132 in the fifth cut line 135. The end opposite to the rear end.

An example of the length L3 of the cut portion 13 in the opening direction D1 (corresponding to the length of the opening direction D1 of the outlet 11) is 30 mm to 230 mm. The length L3 is the distance between the top of the third cut line 133 (the portion most located on the front end side of the base film 10) and the rear end of the cut portion 13.
An example of the length L4 in the direction orthogonal to the opening direction D1 of the cut portion 13 is 30 mm to 130 mm. The length L4 is the distance between the first cut line 131 and the second cut line 132.
An example of the length L5 between the end 134a and the end 135a is 3 mm to 120 mm.

An example of the thickness of the base film 10 is 30 μm to 150 μm. As shown in FIG. 5, the base film 10 is a laminated film having a sealant layer 101 and a base material 102 having a barrier property laminated on the sealant layer 101. FIG. 5 shows a portion of the base film 10 in the region A shown in FIG.

The sealant layer 101 is a layer formed of low-density polyethylene, linear polyethylene, medium-density polyethylene, high-density polyethylene, polypropylene, ethylene / propylene copolymer, ethylene / methyl methacrylate copolymer, ionomer and the like. For the sealant layer, considering the processability and thermal stability of the material of the sealant layer, if necessary, an antioxidant, a stabilizer, a lubricant, an antiblocking agent, an antistatic agent, a cloudproofing agent, and an adhesive adjusting agent. , Additives such as fillers and colorants may be added.

The base material 102 having a barrier property is, for example, a polyvinyl alcohol (PVA) film which is a polyvinyl alcohol resin film, an ethylene / vinyl alcohol copolymer (EVOH) film and a polyvinylidene chloride resin film, and is made of polyvinylidene chloride (PVDC). It is an extruded resin film or a K-coated film in which various plastic films are coated with polyvinylidene chloride. The base material 102 may be a film on which silica, alumina, aluminum or tin is vapor-deposited. The base material 102 may be stretched.

The base film 10 may have another base material on the base material 102. Examples of other substrates are polyethylene terephthalate (PET) film, biaxially stretched polypropylene (OPP: Oriented PolyPropylene) film, paper sheet, polybutylene terephthalate (PBT), cellophane film and the like.

In the base film 10 having the above configuration, the inside of the cut portion 13 is separated from the outside of the cut portion 13 by peeling off the reclose label 20. As a result, as shown in FIG. 3, the inner portion of the cut portion 13 is pulled up together with the reclose label 20 as the film piece 12, and the outlet 11 is formed in the base film 10. That is, the package 1 is opened. Further, by reattaching the reclose label 20 to the base film 10, the film piece 12 closes the take-out port 11 and the package 1 is resealed.

Since the cut portion 13 exhibits an open ring partially opened on the rear end side in the opening direction D1, the connected state between the film piece 12 and the base film 10 is maintained. Therefore, the reclose label 20 is not completely separated from the base film 10, and there is a portion corresponding to the hinge described with reference to FIG. Therefore, when the reclose label 20 is reattached to the base film 10, the outlet 11 is easily closed.

The cut portion 13 has a fourth cut line 134 and a fifth cut line 135 that are folded forward in the vicinity of the end portion 134a and the vicinity of the end portion 135a. Therefore, the length of the connecting portion between the film piece 12 and the base film 10 in the direction orthogonal to the opening direction D1 of the film piece 12 (for example, the length L5) is the length in the cut portion 13 in the direction orthogonal to the opening direction D1. It is shorter than L7. Therefore, the closed label 20 in the opened state is suppressed from being pulled back by the film piece 12. That is, the cut portion 13 having the fourth cut line 134 and the fifth cut line 135 has a configuration for suppressing the return of the reclose label 20 in the opened state.

In order to realize such return suppression of the reclose label 20, the length L5 may be set in consideration of, for example, the rigidity of the base film 10 and the reclose label 20, the size of the cut portion 13, and the like. good.

The close-closed label 20 will be described with reference to FIG. The reclose label 20 is a label having resealability, and is attached to the base film 10 so that the package 1 can be opened and resealed. The reclose label 20 has a knob portion 21 and a label body 22. The reclose label 20 is a film having an adhesive layer on the base film 10 side, and is a film in which a glue-killing layer is formed on a region corresponding to a pinch portion 21 in the adhesive layer.

The picking portion 21 is a portion where the user picks the reclose label 20 with a finger when opening or resealing the package 1. The knob portion 21 is a portion that serves as a starting point at the time of opening. The knob portion 21 is a portion including one end of the reclose label 20 in the opening direction D1 preset in the package 1. In the present embodiment, the knob portion 21 has a trapezoidal shape.

The label main body 22 is a portion that covers the planned outlet portion 14, is adjacent to the grip portion 21 in the opening direction D1, and is integrated with the grip portion 21. In the present embodiment, the label main body 22 has a shape in which a trapezoidal portion continuous from the trapezoidal knob portion 21 and a rectangular portion having the base of the trapezoidal portion as a short side are connected. Therefore, the side edge portion 22a and the side edge portion 22b (the side edge portion facing the side edge portion 22a) of the label main body 22 have a region parallel to the opening direction D1 and a region inclined toward the grip portion 21. ..

An example of the length L6 along the opening direction D1 of the reclose label 20 is 50 mm to 250 mm.
An example of the length L7 in the direction orthogonal to the opening direction D1 of the reclose label 20 is 50 mm to 150 mm.
The length L6 is the distance between the front end of the knob 21 and the rear end of the label body 22. The length L7 is the distance between the side edge portion 22a and the side edge portion 22b parallel to the opening direction D1.

An example of the thickness of the reclose label 20 is 65 μm to 120 μm. As shown in FIG. 6, the reclose label 20 is laminated on the adhesive layer 201, the base material 202 that supports the adhesive layer 201, the print layer 203 laminated on the base material 202, and the print layer 203, and is a barrier. It is a laminated body having a base material 204 having a property. The laminate can be formed, for example, by laminating.

The adhesive layer 201 is a layer for attaching the reclose label 20 to the base film 10, and is formed of an adhesive. Examples of the pressure-sensitive adhesive include solvent-type, emulsion-type or solvent-free (oligoform-type, hot-melt type) acrylic acid ester copolymerization system pressure-sensitive adhesives, and solvents obtained by blending a tack-imparting resin with natural rubber or synthetic rubber. Examples include mold or hot melt type adhesives, calendar coating adhesives, silicon-based adhesives, liquid-curable adhesives obtained by blending a pressure-imparting resin with polyether or diene-based oligomas, and other adhesives. ..
Examples of the base material 202 include an OPP film, a paper sheet, and a PET film.
The printing layer 203 is a layer in which a printing substrate is printed. The printing substrate is, for example, a plastic resin film having good printability such as PET film or polyamide film. For example, a pattern, an arrow indicating the opening direction D1, and the like are printed on the print layer 203.
The example of the base material 204 having the barrier property is the same as that of the base material 102.
Here, the printing layer 203 has been described as a layer in which the printing base material has been printed as described above, but for example, the base material 202 or the base material 204 may be printed.

As shown in FIG. 6, the glue-killing layer 205 is formed on the adhesive layer 201 in the picking portion 21. The glue killing layer 205 is formed of varnish or the like. As a result, the picked portion 21 does not have adhesiveness. The glue-killing layer 205 can be formed by subjecting the adhesive layer 201 to a glue-killing treatment. The glue-killing treatment is a treatment for partially sealing the adhesive force, and examples of the glue-killing treatment include a treatment of printing ink, varnish, or the like on the adhesive layer.

[Unopened revealing part]
Returning to FIG. 4, the reclose label 20 will be further described. The reclosed label 20 (specifically, the label body 22) has two unopened revealing portions 23.

The unopened revealing portion 23 is provided near the knob portion 21 on the outside of the region corresponding to the scheduled outlet portion 14 of the label main body 22. When the two unopened revealing sections 23 are described separately, the two unopened revealing sections 23 are referred to as an unopened revealing section 23A and an unopened revealing section 23B. The unopened revealing portion 23A is arranged near the side edge portion 22a of the label main body 22, and the unopened revealing portion 23B is arranged near the side edge portion 22b of the label main body 22.

In the present embodiment, the configurations of the unopened revealing portion 23A and the unopened revealing portion 23B are symmetrical with respect to the center line C (center line along the opening direction D1) of the reclose label 20. That is, the two unopened revealing portions 23 (the unopened revealing portion 23A and the unopened revealing portion 23B) have the same configuration except that they are symmetrical with respect to the center line C. Therefore, the unopened revealing unit 23 will be described based on the unopened revealing unit 23A.

As shown in FIG. 7, the unopened revealing portion 23 has a break induction line 231 and a break stop line 232. The break induction line 231 and the break stop line 232 are cut lines that are non-parallel to the opening direction D1. The break induction line 231 and the break stop line 232 may be lines that are fully penetrated or half-penetrated (half-cut) in the thickness direction of the reclose label 20. The break induction line 231 and the break stop line 232 may be continuous lines or sewing machine lines. The fracture inducing line 231 and the fracture stop line 232 can be formed, for example, by cutting a blade. In the following description, unless otherwise noted, the rupture inducing line 231 and the rupture stop line 232 are completely penetrating and continuous cut lines in the thickness direction of the reclose label 20.

The fracture induction line 231 is located closer to the knob 21 than the fracture stop line 232 in the opening direction D1. The fracture induction line 231 is an inner end portion 231a located inside the label body 22 (on the side of the center line C shown in FIG. 4) and outside (on the opposite side of the center line C shown in FIG. 4), and is shown in FIG. Has an outer end portion 231b located on the side edge portion 22a side). The fracture induction line 231 is formed, for example, in parallel with the direction orthogonal to the opening direction D1. In the form shown in FIG. 7, the rupture induction line 231 is bent toward the rupture stop line 232 in the vicinity of the outer end portion 231b. An example of the length L8a of the break induction line 231 is 3 mm to 20 mm.

The break stop line 232 is located behind the break induction line 231 in the opening direction D1. The break stop line 232 is located on the inner end portion 232a located inside the label body 22 and on the outer side (the side opposite to the center line C shown in FIG. 4 and the side edge portion 22a side in FIG. 7). It has an end 232b and. The outer end portion 232b is separated from the side edge portion 22a. The break stop line 232 is inclined with respect to the opening direction D1 so that the inner end portion 232a is located closer to the grip portion 21 than the outer end portion 232b in the opening direction D1. That is, the break stop line 232 is formed so as to be separated from the center line C as it is separated from the grip portion 21 along the opening direction D1. An example of the length L8b of the break stop line 232 is 2 mm to 30 mm.

The inner end portion 231a of the fracture induction line 231 is located at the same position as the inner end portion 232a of the fracture stop line 232 or on the side edge portion 22a side when viewed from the opening direction D1. The outer end portion 231b of the break induction line 231 is located inside the label body 22 (center line C side) from the outer end portion 232b of the break stop line 232 when viewed from the opening direction D1. The outer end portion 231b of the fracture induction line 231 is separated from the fracture stop line 232. In the present embodiment, the inner end portion 231a and the inner end portion 232a overlap each other when viewed in a plan view. That is, the break induction line 231 and the break stop line 232 are connected inside the label body 22.

In the arrangement relationship between the rupture induction line 231 and the rupture stop line 232, when the rupture induction line 231 and the rupture stop line 232 are projected on the virtual plane VP orthogonal to the opening direction D1, the projection line 231I of the rupture induction line 231 is , Exists in the projection line 232I of the break stop line 232.

By having the unopened revealing portion 23 having the above configuration, it can be surely confirmed whether or not the package 1 is unopened. This point will be explained.

When the package 1 is in the unopened state, as shown in FIG. 7, there is no break between the break induction line 231 and the break stop line 232. When the user peels off the reclose label 20 along the opening direction D1 from this unopened state, the reclose label 20 is induced to break at the outer end portion 231b of the break induction line 231 which is a cut line. This break progresses along the opening direction D1.

The outer end portion 231b of the break induction line 231 is located inside the label body 22 (center line C side) from the outer end portion 232b of the break stop line 232 when viewed from the opening direction D1. Therefore, the fracture starting from the outer end portion 231b is received by the fracture stop line 232. As a result, the above-mentioned fracture is stopped by reaching the fracture stop line 232 which is a cut line.

When the label body 22 is broken in this way, the portion where the reclose label 20 is broken from the outer end portion 231b toward the break stop line 232 (shown by a two-dot chain line in FIG. 7) and the break induction. The region surrounded by the line 231 and the breaking stop line 232 (the triangular region shown by hatching in FIG. 7) is separated from the label body 22, and as shown in FIG. 8, is used as a label piece 23a on the base film 10. Remains. On the other hand, as shown in FIG. 9, the closed label 20 peeled off from the base film 10 is formed with an opening 22c corresponding to the label piece 23a remaining on the base film 10. FIG. 9 shows a state in which the reclose label 20 peeled off from the base film 10 as shown in FIG. 3 is viewed from the back side (base film 10 or the accommodating portion 7 side).

When the outlet 11 is resealed by reattaching the peeled reclose label 20 to the base film 10, the label piece 23a is arranged in the opening 22c. However, usually, when the reclosed label 20 is reattached, a slight deviation occurs between the design of the label piece 23a and the design around the label piece 23a. By this deviation, it can be confirmed that the package 1 has been opened (that is, it is not in an unopened state).

Further, in the unopened revealing portion 23, when the reclosed label 20 is peeled off and the outlet 11 is opened even once, the break mark caused by the breakage of the label main body 22 shown by the two-dot chain line in FIG. 7 becomes the label main body 22. Occurs in. In this way, when the reclose label 20 is peeled off from the base film 10 even once, break marks that did not occur in the unopened state appear on the reclose label 20. This break mark is maintained even if the outlet 11 is resealed by the reclose label 20. That is, the reclose label 20 has irreversibility. Therefore, even if the reclose label 20 is reattached to the base film 10 so that the design of the label piece 23a and the design around the label piece 23a do not deviate from each other, the package 1 has not been opened. It is reliably indicated by the opening revealing unit 23. In other words, if no break mark can be confirmed in the unopened revealing portion 23, it is surely indicated that the unopened portion is unopened. Therefore, the reclose label 20, the lid 4 and the package 1 provided with the reclose label 20 contribute to the prevention of mischief or the act of opening the package 1 for the purpose of checking the contents.

The fracture of the reclose label 20 from the outer end portion 231b of the fracture induction line 231 toward the fracture stop line 232 due to the peeling of the reclose label 20 proceeds along the peeling direction of the reclose label 20. Therefore, the peeling direction of the reclose label 20 can be grasped based on the break mark generated on the reclose label 20 once peeled off. As a result, when the reclose label 20 is damaged so that the outlet 11 cannot be resealed due to the peeling of the reclose label 20 (in other words, when an unexpected break occurs in the design). It is possible to verify whether or not the damage is caused by peeling the reclose label 20 in a direction different from the opening direction D1 recommended in advance.

In the form in which the break stop line 232, which is a cut line, is inclined with respect to the opening direction D1 so that the inner end portion 232a is located closer to the grip portion 21 than the outer end portion 232b in the opening direction D1, the outer end is formed. When the fracture stop line 232 receives the fracture generated from the portion 231b, the fracture is likely to propagate outward. As a result, damage to the reclose label 20 that hinders resealability can be suppressed.

In the form in which the vicinity of the outer end portion 231b of the fracture induction line 231 is bent toward the fracture stop line 232, the fracture from the outer end portion 231b toward the fracture stop line 232 is more likely to be induced. As a result, it is possible to prevent unexpected breakage in the design.

[First fracture induction part]
As shown in FIG. 4, the reclose label 20 may have two first break guides 24. The two first breakage guiding portions 24 are provided corresponding to the two unopened revealing portions 23. When the two first fracture guiding portions 24 are described separately, the first fracture guiding portion 24 corresponding to the unopened revealing portion 23A is referred to as the first fracture guiding portion 24A, and the first fracture corresponding to the unopened revealing portion 23B is described. The induction portion 24 is referred to as a first fracture induction portion 24B.

In the present embodiment, the configurations of the first fracture guiding portion 24A and the first fracture guiding portion 24B are symmetrical with respect to the center line C of the reclose label 20. That is, the two first fracture guiding portions 24 (the first fracture guiding portion 24A and the first fracture guiding portion 24B) have the same configuration except that they are symmetrical with respect to the center line C. Therefore, the first fracture guiding portion 24 will be described based on the first fracture guiding portion 24A corresponding to the unopened revealing portion 23A.

As shown in FIG. 10, the first fracture guiding portion 24 is located on the opposite side (that is, the rear side) to the picking portion 21 when viewed from the unopened revealing portion 23. The first breakage guiding portion 24 has a function of guiding the breakage of the reclose label 20 newly generated from the unopened revealing portion 23 (specifically, from the outer end portion 232b) in the outward direction. The first breakage guiding portion 24 is arranged between the unopened revealing portion 23 and the side edge portion 22a so as to partially overlap the region on the side edge portion 22a side of the unopened revealing portion 23 when viewed from the opening direction D1. ing.

The first break guide portion 24 has a plurality of break guide lines 241. The plurality of break guide lines 241 are cut lines that are non-parallel to the opening direction D1. The break guide wire 241 may be a cut wire that fully penetrates in the thickness direction of the reclose label 20, or may be a cut wire that penetrates halfway (half cut). The break guide wire 241 may be a continuous cut wire or a sewing machine wire. The fracture guide wire 241 can be formed by, for example, cutting a blade. In the following description, unless otherwise noted, the fracture lead wire 241 is a continuous cut line that fully penetrates in the thickness direction of the reclose label 20.

In the present embodiment, each breaking guide line 241 is linear and parallel to the breaking stop line 232. An example of the length L9 of each breaking guide wire 241 is 2 mm to 10 mm. The length L9 of the plurality of break guide lines 241 may be the same as or different from each other. Each break guide line 241 is opened in the opening direction so that the inner end portion 241a (the end portion on the center line C side) is located closer to the grip portion 21 than the outer end portion 241b (the end portion opposite to the inner end portion 241a). It is an inclined portion inclined with respect to D1. The outer end portion 241b of the fracture guide wire 241 located at the rearmost position among the plurality of fracture guide wires 241 is located on the side edge portion 22a. The outer end portion 241b of the fracture guide line 241 located at the rearmost position may be slightly separated from the side edge portion 22a so that the fracture propagated to the outer end portion 241b can propagate to the side edge portion 22a. ..

The plurality of break guide lines 241 are arranged so as to be separated from each other along the opening direction D1 and to be displaced toward the outside in a stepwise manner. Of the two adjacent break guide wires 241 in the opening direction D1, the front break guide wire 241 is referred to as the first break guide wire 241A, and the rear break guide wire 241 is referred to as the second break guide wire 241B. The arrangement relationship of the fracture guide wire 241 will be described.

In the plurality of break guide wires 241 the first break guide wire 241A and the second break guide wire 241B are separated from each other along the opening direction D1, and the region on the outer end portion 241b side of the first break guide wire 241A and the first 2 The region on the inner end portion 241a side of the breaking guide wire 241B is arranged so as to partially overlap with the opening direction D1. In the present embodiment, the region on the outer end portion 241b side of the first break guide line 241A and the region on the inner end portion 241a side of the second break guide line 241B are viewed from the direction orthogonal to the second break guide line 241B. overlapping.

The break guide line 241 closest to the break stop line 232 among the plurality of break guide lines 241 is separated from the break stop line 232 along the opening direction D1 and is on the outer end portion 232b side of the break stop line 232. The region and the region on the inner end portion 241a side of the fracture guide line 241 are arranged so as to partially overlap each other when viewed from the direction orthogonal to the fracture stop line 232. In the present embodiment, the region on the outer end portion 232b side of the fracture stop line 232 and the region on the inner end portion 241a side of the fracture guide line 241 overlap even when viewed from the direction orthogonal to the fracture guide line 241.

For example, if the distance between the overlapping regions of the two adjacent fracture guide lines 241 is too wide, the fracture caused by the front fracture guide wire 241 may not be received by the next fracture guide wire 241. If the width of the overlapping region of the two adjacent fracture guide wires 241 is too wide, the fracture guide wire 241 that has received the fracture generated from the front fracture guide wire 241 may induce the fracture toward the center side of the label. In consideration of such a point, the distance and width of the overlapping region of the two adjacent fracture guide lines 241 are set so that the fracture generated from the outer end portion 232b of the fracture stop line 232 can be guided outward. The same applies to the spacing and width of the overlapping region between the breaking guide line 241 closest to the breaking stop line 232 and the breaking stop line 232 among the plurality of breaking guide lines 241.

The plurality of fracture guide lines 241 may be arranged so as to satisfy the following arrangement condition X.

<Arrangement condition X>
The length between the first fracture guide line 241A and the second fracture guide wire 241B in the overlapping region α of the first fracture guide wire 241A and the second fracture guide wire 241B when viewed from the direction orthogonal to the second fracture guide wire 241B. The length d2 of the overlapping region α of the first breaking guide wire 241A and the second breaking guide wire 241B is 1/10 to 1/3 of the length of the second breaking guide wire 241B.

When the first break guide line 241A and the second break guide line 241B are straight lines and are arranged in parallel, the length d1 is a direction orthogonal to the first break guide line 241A (or the second break guide line 241B). Is the distance between the first break guide line 241A and the second break guide line 241B, and the length d2 is the first break guide line 241A and the second break guide when viewed from the direction orthogonal to the second break guide line 241B. It is the length in the extending direction of the first break guide line 241A (or the second break guide line 241B) of the overlapping region α with the line 241B.

When the plurality of fracture guide lines 241 satisfy the above-mentioned arrangement condition X, the fracture guide wire 241 closest to the unopened revealing portion 23 (corresponding to the fracture guide wire 241 located on the frontmost side) among the plurality of fracture guide wires 241 When the break stop line 232 is regarded as the first break guide line 241A and the break guide line 241 closest to the unopened revealing portion 23 is regarded as the second break guide line 241B, the break is broken so as to satisfy the arrangement condition X. Arranged with respect to the stop line 232.

When the reclose label 20 is first peeled off, as described above, breakage occurs from the breakage induction line 231 to the breakage stop line 232 along the opening direction D1. The break itself along the opening direction D1 stops at the break stop line 232, but a new break may occur from the outer end portion 232b of the break stop line 232. Breakage from the outer end portion 232b of the break stop line 232 may also occur when the take-out port 11 is resealed with the reclose label 20 and then reopened.

In the form in which the reclose label 20 has the first break guide portion 24, the break from the outer end portion 232b is caused by the first break guide portion 24 along the first route R1 indicated by the two-dot chain arrow in FIG. , Can be guided outward (to the side edge 22a). Specifically, the break from the outer end portion 232b is received by the break guide line 241. The next fracture guide wire 241 receives a new fracture generated from the outer end portion 241b of the fracture guide wire 241. By repeating such propagation of the fracture, the fracture is propagated outward along the first route R1 in FIG.

Since the first break guide portion 24 guides the break of the reclose label 20 in the outward direction, even if the reclose label 20 is peeled off in a direction D2 different from the opening direction D1, the first break guide portion 24 is peeled from the outer end portion 232b. It is possible to prevent the breakage of the reclose label 20 from progressing toward the center of the reclose label 20. As a result, it is possible to prevent the reclose label 20 from being damaged to some extent because the outlet 11 cannot be resealed. As a result, the outlet 11 can be reliably resealed using the reclose label 20.

In particular, when a plurality of break guide lines 241 are arranged so as to satisfy the above arrangement condition X, even if a break occurs along a direction other than the opening direction D1 by satisfying the above conditions for the length d1, the break guide line 241 It is possible to receive the fracture, and if the length d2 of the overlapping region α satisfies the above condition, the fracture received can be easily propagated to the outside. As a result, as described above, even if the reclose label 20 is peeled off in the direction D2, it is possible to further prevent the breakage from the outer end portion 232b from proceeding toward the center of the reclose label 20. As a result, it is possible to prevent the reclose label 20 from being damaged to some extent because the outlet 11 cannot be resealed.

[Second fracture induction part]
As shown in FIG. 4, the reclose label 20 has two second fracture guiding portions 25 in a region corresponding to the vicinity of the rear end portion (rear end portion of the planned outlet portion 14) of the cut portion 13. You may. When the two second fracture guiding portions 25 are described separately, the two second fracture guiding portions 25 are referred to as a second fracture guiding portion 25A and a second fracture guiding portion 25B. The second fracture guiding portion 25A is arranged between the side edge portion 22a of the label main body 22 and the notch portion 13, and the second fracture guiding portion 25B is the side edge portion 22b and the notch portion 13 of the label main body 22. It is placed between.

In the present embodiment, the configurations of the second fracture guiding portion 25A and the second fracture guiding portion 25B are symmetrical with respect to the center line C of the reclose label 20. That is, the two second fracture guiding portions 25 (the second fracture guiding portion 25A and the second fracture guiding portion 25B) have the same configuration except that they are symmetrical with respect to the center line C. Therefore, the second fracture guiding portion 25 will be described based on the second fracture guiding portion 25A on the side edge portion 22a side.

The second fracture guiding portion 25 is arranged between the first cutting line 131 and the side edge portion 22a. The second breakage guiding portion 25 is configured to reduce the force of the reclose label 20 to return to the base film 10 side when the outlet 11 is exposed by peeling off the reclose label 20. That is, the second breakage guiding unit 25 functions as a return suppressing unit that suppresses the return of the reclose label 20. Specifically, as shown in FIG. 3, the second fracture guiding portion 25 is a case where the reclose label 20 is peeled off to the vicinity of the rear end portion of the cut portion 13, and the reclose label 20 and the base film 10 are attached to each other. It is configured to reduce the width of the connecting portion.

An example of the second fracture guiding portion 25 will be described with reference to FIG. 12. The second fracture guide portion 25 has a plurality of fracture guide lines 251. The plurality of break guide lines 251 are cut lines that are non-parallel to the opening direction D1. The break guide wire 251 may be a cut wire that fully penetrates in the thickness direction of the reclose label 20, or may be a cut wire that penetrates halfway (half cut). The break guide wire 251 may be a continuous cut wire or a sewing machine wire. The fracture guide wire 251 can be formed, for example, by processing a blade. In the following description, unless otherwise noted, the break guide wire 251 is a continuous cut line that fully penetrates in the thickness direction of the reclose label 20.

Each break guide line 251 is an inclined portion inclined with respect to the opening direction D1 so that the outer end portion 251a is located closer to the grip portion 21 than the inner end portion 251b. In the present embodiment, each breaking guide line 251 is a straight line, and a plurality of breaking guide lines 251 are arranged in parallel with each other.

The plurality of break guide lines 251 are separated along the opening direction D1 and are arranged so as to be shifted in a stepwise manner toward the inside (center line C side). Of the two adjacent break guide wires 251 in the opening direction D1, the front break guide wire 251 is referred to as the first break guide wire 251A, and the rear break guide wire 251 is referred to as the second break guide wire 251B. Explain to.

In the plurality of break guide lines 251 the first break guide line 251A and the second break guide line 251B are separated from each other along the opening direction D1, and the region on the inner end portion 251b side of the first break guide line 251A and the first 2 The region on the outer end portion 251a side of the breaking guide wire 251B is arranged so as to partially overlap with the opening direction D1. In FIG. 12, as an example of a set of the first break guide line 251A and the second break guide line 251B, the break guide line 251 located at the frontmost position among the plurality of break guide lines 251 and the break guide located at the frontmost position thereof. Although the pair with the breaking guide line 251 adjacent to the line 251 is shown, the above arrangement relationship is the same for the other two adjacent breaking guide lines 251 in the plurality of breaking guide lines 251.

The outer end portion 251a of the breaking guide wire 251 located at the foremost position (on the knob portion 21 side) of the plurality of breaking guide wires 251 is located on the side edge portion 22a. The outer end portion 251a of the fracture guide line 251 located at the foremost position has a fracture at the side edge portion 22a and the fracture occurs to the extent that the fracture propagates from the outer end portion 251a to the fracture guide line 251 with the side edge portion 22a. It may be slightly separated. The inner end portion 251b of the fracture guide wire 251 located at the rearmost position (opposite to the knob portion 21) of the plurality of fracture guide wires 251 is located, for example, on (or near) an extension of the first cut line 131. ..

In the second breaking guide portion 25 having the above configuration, when the reclose label 20 is peeled off to the outer end portion 251a of the breaking guide wire 251 located at the frontmost position (the knob portion 21 side) of the plurality of breaking guide wires 251. The close label 20 breaks. Since the fracture guide line 251 is a cut line, the fracture of the side edge portion 22a propagates to the inner end portion 251b of the fracture guide wire 251. With the peeling of the reclose label 20, breakage occurs from the inner end portion 251b along the opening direction D1. This break is received by the next break lead wire 251. Since such propagation of fractures is repeated among the plurality of fracture guide lines 251 that the fractures that occur at the side edge portion 22a are inside the reclose label 20, as shown by the alternate long and short dash arrow in FIG. Be propagated. By breaking the reclose label 20 in the vicinity of the rear end portion of the cut portion 13 in this way, the width of the connecting portion between the reclose label 20 and the base film 10 when peeled off is reduced. As a result, the force of the reclose label 20 peeled off from the base film 10 to return to its original state is weakened. As a result, it is possible to prevent the user from unintentionally blocking the outlet 11 with the reclose label 20, and it is easy for the user to take out the contained material 2 from the outlet 11.

The distance between the two adjacent break guide lines 251 of the plurality of break guide lines 251 and the overlap of the two break guide lines 251 viewed from the opening direction D1 (or from the direction orthogonal to the break guide line 251). The length of the region may be set so that the second fracture guiding portion 25 exhibits the return suppressing function. The distance between the two adjacent fracture guide lines 251 and the length of the overlapping region correspond to the length d1 and the length d2 in the first fracture guide portion 24.

(Second Embodiment)
A second embodiment of the reclose label will be described with reference to FIG. FIG. 13 is an enlarged drawing of the area on the knob side when the reclose label is viewed from the back side (the side to be attached to the base film 10).

The reclose label 20A shown in FIG. 13 differs from the reclose label 20 in that it does not have the first fracture guiding portion 24 and the glue killing layer 206 is formed along the fracture stop line 232. Since the configuration of the reclose label 20A other than the above differences is the same as that of the reclose label 20, the reclose label 20A will be described focusing on the differences.

The glue killing layer 206 is provided on the adhesive layer 201 along the breaking stop line 232. In other words, the fracture stop line 232 is formed along the glue killing layer 206 at the portion where the glue killing layer 206 is formed. The example of the glue killing layer 206 may be the same as the glue killing layer 205 included in the picking portion 21. The width of the glue-killing layer 205 (the length in the direction orthogonal to the extending direction of the glue-killing layer 205) can form a break stop line 232, and when the reclose label 20A is attached to the base film 10. The width may be such that the adhesiveness and the adhesiveness of the label piece 23a can be ensured. The glue killing layer 206 may be formed up to the side edge portion 22a (side edge portion 22b) of the label main body 22.

In the reclose label 20A, the break stop line 232 is formed at the position of the glue killing layer 206. When such a reclose label 20A is attached to the base film 10, the periphery of the break stop line 232 is not attached to the base film 10. Therefore, the breaking stop line 232 is in a uniform state over the entire breaking stop line 232. Therefore, the fracture that occurs at the outer end portion 232b tends to go outward as designed. In particular, for example, even when the package is opened in a direction different from the opening direction D1, in the form having the glue killing layer 206, the breakage that occurs at the outer end portion 232b tends to go outward. As a result, the reclose label 20A can prevent unnecessary breakage that hinders the resealing of the outlet 11 by the reclose label 20A, and the reclose label 20A can more reliably reseal the outlet 11. ..

The reclose label 20A may have two first break induction portions 24 that the reclose label 20 has. In this case, the glue killing layer 206 is formed up to the region where the first fracture guiding portion 24 is formed. In other words, the fracture stop line 232 and the first fracture induction portion 24 are formed in the portion where the glue killing layer 206 is formed.

Although various embodiments of the present invention have been described above, the present invention is not limited to the above-exemplified embodiments, but includes the scope indicated by the claims and is equivalent to the scope of the claims. It is intended to include all changes within the meaning and scope of.

The unopened revealing portion may be the unopened revealing portion 23_1 as shown in FIG. The unopened revealing portion 23_1 is mainly different from the unopened revealing portion 23 in that the inner end portion 231a of the breaking induction line 231 and the inner end portion 232a of the breaking stop line 232 are separated from each other. The inner end portion 231a overlaps with the inner end portion 232a or is located outside the inner end portion 232a (for example, on the side edge portion 22a side in FIG. 4) when viewed from the opening direction D1. In the unopened revealing portion 23_1, the reclose label 20 is broken from the inner end portion 231a along the opening direction D1 as in the case of the outer end portion 231b. Since the inner end portion 231a and the inner end portion 232a have the above-mentioned arrangement relationship, the fracture generated from the inner end portion 231a is received by the fracture stop line 232. Therefore, as shown in FIG. 14, the region surrounded by the two-dot chain line schematically showing the fracture generated from the inner end portion 231a and the outer end portion 231b, the fracture induction line 231 and the fracture stop line 232 is formed. It remains on the base film 10 as a label piece, and the reclosed label 20 has an opening at a position corresponding to the label piece remaining on the base film 10. Further, since the reclose label 20 once peeled off has a break mark (break mark) generated from the inner end portion 231a and the outer end portion 231b, the package having the reclose label 20 was opened. Can be confirmed with certainty.

The shape and arrangement relationship of the break induction line 231 and the break stop line 232 have been described in the above embodiment if the break of the reclose label 20 generated from the break trigger line 231 is set so as to be received by the break stop line 232. It is not limited to the shape and arrangement.

For example, the rupture induction line 231 may be a line substantially parallel to the rupture stop line 232 as shown in FIG. Alternatively, the fracture induction line 231 may be a line inclined with respect to the opening direction D1 so that the outer end portion 231b is located in front of the inner end portion 231a (on the side of the grip portion).

The unopened revealing portion may be the unopened revealing portion 23_2 as shown in FIG. 15 (a). The unopened revealing portion 23_1 differs from the unopened revealing portion 23_1 in that the rupture-inducing line 231 is bent near the central portion between the inner end portion 231a and the outer end portion 231b. The unopened revealing portion may be the unopened revealing portion 23_3 as shown in FIG. 15 (b). The unopened revealing portion 23_1 is different from the unopened revealing portion 23_1 in that the fracture induction line 231 is curved. Since the configurations of the unopened revealing section 23_2 and the unopened revealing section 23_3 other than the above-mentioned differences are the same as those of the unopened revealing section 23_1, the unopened revealing section 23_2 and the unopened revealing section 23_1 are the unopened revealing section 23_1. It has the same effect as.

Although the deformation example of the shape of the fracture inducing line 231 has been described with reference to FIGS. 14 and 15, the shape of the fracture stop line 232 is also the fracture of the reclose label 20 generated from the fracture inducing line 231. The shape is not limited to the exemplified shape as long as the shape can be received by the break stop line 232.

The shape of the label piece (for example, the label piece 23a shown in FIG. 8) remaining on the base film 10 side due to the break generated from the break induction line 231 to the break stop line 232 is not limited to the triangle as shown in FIG. .. The label piece may be a polygon other than a triangle, or may be a circle. The shape of the label piece can be set by the arrangement relationship and shape of the break induction line 231 and the break stop line 232. In other words, the arrangement relationship and shape of the fracture inducing line 231 and the fracture stop line 232 can be selected so as to realize the desired label piece shape.

The unopened revealing portions 23_1, 23_2, 23_3 shown in FIGS. 14 and 15 (a) and 15 (b) are unopened revealing portions 23 (unopened revealing portions 23A) arranged on the side edge portion 22a side in FIG. ) Is supported. However, the same modification can be applied to the unopened revealing portion 23 (unopened revealing portion 23B) arranged on the side edge portion 22b side in FIG.

As shown in FIG. 4, when the reclose label has two unopened reveals, the two unopened reveals do not have to be symmetrical with respect to centerline C (see FIG. 4). Similarly, if the reclose label has two first break guides, the two first break guides do not have to be symmetrical with respect to the centerline C. Similarly, if the reclose label has two second rupture inducers, the two second rupture inducers do not have to be symmetrical with respect to the centerline C.

The first fracture guiding portion may be configured so as to be able to guide the fracture generated from the outer end portion of the fracture stop line in the outward direction. The first fracture guide portion may be composed of one fracture guide wire or may be composed of three or more fracture guide wires.

When the first fracture guide portion is one fracture guide line, the arrangement relationship between the fracture stop line and the fracture guide line regards the fracture stop line as the first fracture guide line under the above arrangement condition X, and the first fracture guide portion. When the second break guide line under the above arrangement condition X is regarded as the break guide line, the arrangement relationship may satisfy the above arrangement condition X. That is, the arrangement relationship between the rupture stop line and the rupture guide line is the distance between the rupture stop line and the rupture guide line in the overlapping region between the outer part of the rupture stop line and the inner part of the rupture guide line when viewed from the rupture guide line. And each of the lengths in the direction parallel to the fracture guide line in the overlapping region may satisfy the arrangement condition that the length is 1/10 to 1/3 of the length of the fracture guide line.

The number of unopened revealing portions included in the reclose label is not limited to two, and may be one, for example. When the reclose label has a first break guide portion, the number of the first break guide portions may be a number corresponding to the number of unopened reveal portions. When the reclose label has a second break guide portion, the number of the second break guide portions is not limited to two, and may be one, for example.

The shape of the outlet formed on the base film is not limited to the exemplified shape. The shape of the cut portion (or the planned outlet portion) for forming the outlet is not limited to the exemplified shape. For example, the notch may be U-shaped without the fourth cut line 134 and the fifth cut line 135 in FIG. Alternatively, the cut portion may be a closed annular cut portion in which the rear end portions of the first cut line 131 and the second cut line 132 are connected by a cut line. The cut portion may be a circle, an ellipse, a quadrangle (for example, a rectangle, a square, etc.), or a polygon other than the quadrangle.

The configurations of the unopened revealing portion, the first breaking guiding portion and the second breaking guiding portion can be appropriately changed without departing from the spirit of the present invention.

The plan-view shape of the reclose label is not limited to the exemplified shape. For example, the side edge portion (the portion corresponding to the trapezoidal leg) of the trapezoidal knob portion may be curved. The knob side may be curved.

The storage container to which the lid with the reclose label is joined is not limited to the tray-shaped container as shown in FIG. The shapes of the base film, the reclosed label, and the like correspond to the shape of the storage container. The shape of the outlet is not limited to the exemplified shape. In the description of the base film and the closed label, the dimensions and the like exemplified are examples based on the above-described embodiment as described above.

The package is, for example, a main body portion (for example, a packaging bag or the like) in which a notch portion (corresponding to the notch portion 13 in FIG. 4) for accommodating the contents and forming an outlet is formed on one side surface. , A package with a reclose label may be used. In this case, one side surface of the main body functions as a support member to which the reclose label is attached.

The knob may have less stickiness than the stickiness of the label body. As long as the picked portion is formed to have a stickiness smaller than the stickiness of the label body (including the case where it does not have the stickiness), the method for forming the picked portion is not limited to the glue-killing treatment.

The various embodiments and various modifications described above may be appropriately combined as long as they do not deviate from the gist of the present invention.

The present invention will be further described with reference to examples. The present invention is not limited to the examples described below. In the description of the embodiment, the same elements as those of the base film and the reclose label described in the first embodiment and the second embodiment are designated by the same reference numerals, and duplicate description will be omitted.

The length L14 was 28.5 mm.

As shown in FIG. 17, the unopened revealing portion 23 had a break induction line 231 and a break stop line 232, and the first break guide portion 24 had two break guide lines 241. .. The break induction line 231, the break stop line 232, and the break guide line 241 completely penetrated the reclose label 20 and were continuous cut lines. FIG. 17 shows an unopened revealing portion 23 (unopened revealing portion 23A) arranged on the side edge portion 22a side as in the case of the above embodiment.

The fracture induction line 231 was bent parallel to the first region parallel to the width direction of the reclose label 20 and the side edge portion 22a of the label body 22 corresponding to the leg of the trapezoidal portion from the outer end portion of the first region. It had a second area.
The distance L15 between the first region and the upper side of the trapezoidal portion was 5 mm.
The distance L16 between the second region and the side edge portion 22a of the label main body 22 was 5 mm.
The length L17 of the second region was 1.5 mm.

The fracture stop line 232 was a straight line inclined so that the angle θ formed from the inner end portion 231a of the first region of the fracture induction line 231 to the fracture induction line 231 was 30 degrees. The connection portion between the break induction line 231 and the break stop line 232 was rounded.

The two breaking guide lines 241 were straight lines parallel to the breaking stop line 232. The two breaking guide lines 241 were separated from each other along the opening direction D1 and were formed in a stepped manner toward the outside. The length L9a of the rupture guide wire 241 (referred to as “front rupture guide wire 241”) on the side close to the rupture stop line 232 was 5 mm. The distance d1a between the breaking guide line 241 on the front side and the breaking stop line 232 was 1 mm. The length d2a of the overlapping region α1 between the breaking guide line 241 and the breaking stop line 232 on the front side was 0.8 mm.

The length L9b of the fracture guide wire 241 (referred to as “rear fracture guide wire 241”) located on the side opposite to the fracture stop line 232 as seen from the fracture guide wire 241 on the front side was 7 mm. The distance d1b between the breaking guide wire 241 on the rear side and the breaking guide wire 241 on the front side was 1 mm. The length d2b of the overlapping region α2 between the fracture guide wire 241 on the rear side and the fracture guide wire 241 on the front side was 0.8 mm. The outer end portion 241b of the breaking guide wire 241 on the rear side was located on the side edge portion 22a of the label main body 22.

The unopened revealing portion 23 and the first fracture guiding portion 24 arranged in the vicinity of the side edge portion 22a have been described. The unopened revealing portion 23 and the first fracture guiding portion 24 arranged in the vicinity of the side edge portion 22b had a configuration symmetrical with respect to the center line of the reclose label 20 (center line C in FIG. 4).

As shown in FIG. 16, the second fracture guide portion 25 had four fracture guide lines 251. The break guide line 251 was a continuous cut line that completely penetrated the reclose label 20. The outer end portion 251a of the frontmost breakage guide line 251 of the four breakage guide lines 251 is on the side edge portion 22a (or the side edge portion 22b) at a position 20 mm from the rear end of the reclose label 20. It was located. The four break guide lines 251 were straight lines, the frontmost break guide line 251 had a length of 4 mm, and the other three break guide lines 251 had a length of 5 mm.

The four breaking guide lines 251 were inclined toward the inside of the reclose label 20 at an angle of 40 degrees with respect to the opening direction D1. In the opening direction D1, the distance between the two adjacent breaking guide lines 251 was 1 mm. Of the two adjacent rupture guide lines 251, the length of the overlapping region near the inner end of the rupture guide line 251 on the front side and the outer end of the rupture guide line on the rear side (direction along the rupture guide line). The length) was also 1 mm.

With respect to the base film 10 prepared in Example 1, the distance L18 (and the second cut line 132 and the side edge portion 22b) between the first cut line 131 and the side edge portion 22a of the cut portion 13 The reclose label 20 is attached so that the distance L19 between the rear end portion of the notch 13 and the rear end portion of the reclose label 20 is 10 mm. A lid sample for 1 was prepared.

In Example 1, 10 sheets of the above lid sample were prepared. For each lid sample, the reclose label 20 was peeled from the base film 10 along the opening direction D1 by holding the knob portion 21. With this peeling, whether or not the fracture progresses from the outer end portion 231b of the fracture induction line 231 along the opening direction D1 and the triangular label piece 23a shown in FIG. 8 is formed on the base film 10. I confirmed that.

As a result, it was confirmed that the triangular label piece 23a was formed on the base film 10 in all the 10 lid samples. Further, as described above, since the fracture occurs along the opening direction D1 from the outer end portion 231b of the fracture induction line 231, it can be confirmed that the peeled reclose label 20 has a trace of peeling (break mark). rice field.

(Example 2)
In Example 2, the length L9a of the front fracture guide wire 241 of the first fracture guide portion 24 shown in FIG. 15, the length L9b of the rear fracture guide wire 241, the length d2a of the overlapping region α1, and the overlap. Nine reclose labels 20 were prepared in which the length d2b, the interval d1a and the interval d1b of the region α2 were changed as shown in Table 1.

In each reclose label 20, the position and length of the break induction line 231 were the same as those of the reclose label 20 described in Example 1. Therefore, in each reclose label 20, the length of the break stop line 232 is adjusted so as to realize the lengths L9a and L9b, the intervals d1a and d1b and the lengths d2a and d2b. In each reclose label 20, points other than the lengths L9a and L9b, the intervals d1a and d1b and the lengths d2a and d2b, and the length of the break stop line 232 adjusted to realize them are described in Example 1. It was the same as the reclose label 20 described.

In Example 2, the prepared nine reclose labels 20 were attached to the base film 10 described in Example 1 in the same manner as in the case of Example 1, and nine lid samples were prepared.

In each prepared lid sample, as shown in FIG. 11, the reclose label 20 was peeled off in a direction D2 different from the preset opening direction D1 (longitudinal direction). In Example 2, the angle formed by the opening direction D1 and the direction D2 was 45 degrees. Due to the peeling in the direction D2, the break from the outer end portion 232b of the break stop line 232 propagates along the first route R1 toward the outside of the label or toward the center of the label, as shown in FIG. It was confirmed whether it propagated along the 2 route R2.

As a result, it was confirmed that the fracture was propagated outward along the first route R1 in all the lid samples because the first fracture guiding portion 24 was provided.

If the break progresses along the second route R2, the reclose label 20 breaks toward the center of the label and cannot be resealed. Therefore, it has been verified that the function of the reclose label 20 can be ensured even if the user accidentally opens the label in a direction different from the opening direction D1 by providing the first breakage guiding portion 24.

Under the conditions shown in Table 1, the arrangement relationship between the fracture guide wire 241 on the front side and the fracture guide wire 241 on the rear side satisfied the arrangement condition X described in the above embodiment. Further, when the break stop line 232 is regarded as the first break guide line 241A under the above arrangement condition X and the front break guide line 241 is regarded as the second break guide line 241B under the above arrangement condition X, the break stop is stopped. The arrangement relationship between the wire 232 and the fracture guide wire 241 on the front side also satisfied the above arrangement condition X.

(Example 3)
In Example 1, except that the first fracture guiding portion 24 was not formed and the glue-killing layer 206 was formed on the back surface (on the adhesive layer) along the fracture stop line 232 as shown in FIG. Thirteen reclose labels having the same configuration as the reclose label 20 were prepared. The glue killing layer 206 was formed up to the side edge portion 22a (side edge portion 22b) as shown in FIG.

Each of the 13 reclose labels prepared in Example 3 was attached to the base film 10 in the same manner as in the case of Example 1, and 13 lid samples were prepared. After that, as in the second embodiment, the grip portion 21 is lifted and the reclose label is peeled off in the direction D2 (see FIG. 11), and the outer end portion 232b of the break stop line 232 is used as a starting point on the center side of the label. It was confirmed whether or not the label was broken. The direction D2 was 45 degrees with respect to the opening direction D1 as in the case of the second embodiment. As a result, in the 13 lid samples prepared in Example 3, no breakage to the center side of the label starting from the outer end portion 232b of the break stop line 232 was confirmed.

Therefore, it was verified that the glue killing layer 206 can prevent damage that makes it impossible to reseal.
