Technical Field
[0001] The present invention relates to a lid label and a packaged product with a lid label.
Background Art
[0002] Conventionally, a packaged product with a lid label, in which a repeatedly peelable lid label is attached to an opening of a package containing contents, is widely known. In such a packaged product with a lid label, by peeling off the lid label in a cantilevered manner while leaving a part of the lid label, the opening is exposed, and after taking out the contents from the opening, the lid label is attached again to seal the opening.
[0003] For example, in order to make it easier to open the lid label as in Patent Document 1, there is an example in which a peeling start portion is formed in a concavo-convex shape and a gap is provided between the package and the lid label. Further, in Patent Document 2, in order to expose the opening portion, after pinching the lid label and starting to peel it from the package and standing the lid label up, a lid label having a cut provided in the cantilevered portion is disclosed so that the lid label does not naturally return even when the hand is released from the lid label.

Summary of the Invention
Problems to be Solved by the Invention
[0005] When creating a lid label that is easy to open and does not naturally close once opened by using the technologies of Patent Document 1 and Patent Document 2, both cutting and molding need to be performed on the lid label, so the manufacturing process becomes complicated, lacking in practicality and difficult to introduce.
[0006] Based on the above circumstances, the present invention aims to provide a lid label that is easy to manufacture, easy to open, and difficult to close once opened, as well as a package with a lid label. [Means for solving the problem]
[0007] In one aspect of the present invention, the lid label comprises: a sheet-like or film-like lid portion that opens and closes an opening formed in a packaging body containing contents; a support portion connected to at least a part of the lid portion and having a first adhesive portion on its back surface that is attached to the packaging body; a second adhesive portion provided on the edge of the back surface of the lid portion and composed of a repeatedly peelable adhesive portion; a first notch line formed in a straight line penetrating in the thickness direction at the boundary between the lid portion and the support portion; secondary notches formed extending from both ends of the first notch line toward the support portion and penetrating in the thickness direction; and a gripping portion provided at a position spaced apart from the first adhesive portion and at the end of the lid portion, wherein at least the edge of the gripping portion has a convex portion that protrudes toward the surface side of the back surface of the lid portion.
[0008] In one aspect of the present invention, a package with a lid label comprises a package body having an opening for containing contents and for removing the contents, and the lid label provided at a position covering the opening, to which the lid portion is attached so as to be repeatedly peeled off and reattached, wherein the convex portion of the gripping portion is spaced apart from the surface on the package body to which the lid label is attached. [Effects of the Invention]
[0009] According to the present invention, it is possible to provide a lid label that is easy to manufacture, easy to open, and difficult to close once opened, as well as a package with a lid label. [Brief explanation of the drawing]

[Figure 8] Figure 6 is a cross-sectional view of BB. [Modes for carrying out the invention]
[0011] (First Embodiment) A lid label and a package with a lid label according to one embodiment of the present invention will be described with reference to Figures 1 to 8. Figure 1 is a perspective view showing an example of a package with a lid label 10 (hereinafter referred to as "packaging container 10") according to this embodiment. The packaging container 10 consists of a packaging bag (packaging body) 1 for containing the contents and a lid label 2 attached to the packaging bag 1. One side (adhesive side) of the packaging bag 1 has an opening 11 from which the contents are removed when in use. The shape of the opening 11 can be set as appropriate, but in this embodiment it is rectangular in plan view. The lid label 2 is provided at a position on the adhesive side of the packaging bag 1 to open and close the opening 11.
[0012] The packaging bag (packaging body) 1 is formed into a predetermined shape to contain the contents. The packaging bag 1 is formed from a known laminated film, for example, by sequentially laminating and joining polyethylene terephthalate (PET) film, aluminum foil, and a heat-sealable film known as a sealant from the surface (outside). The laminated film may be, for example, a PET film on which aluminum, silica, or alumina has been vapor-deposited, with a heat-sealable film layered on the inner surface.
[0013] The packaging bag 1 is formed with a heat-sealable film on the inside and contains its contents. In this embodiment, the contents include, for example, wet wipes impregnated with a chemical solution, disinfectant, lotion, etc., made of nonwoven fabric or tissue paper. The laminated film forming the packaging bag 1 is impermeable to water and oxygen and has excellent airtightness, so it prevents the wet wipes from drying out and keeps them moist until use. The specific shape of the packaging bag 1 and the layer configuration of the laminated film constituting the packaging bag 1 may be appropriately changed according to the characteristics of the contents.
[0014] The lid label 2 is attached to the packaging bag 1 in a way that allows for repeated peeling, and when attached to the packaging bag 1, it covers the opening 11 so that the contents are not exposed.
[0015] The lid label 2 is composed of, for example, multiple sheet-like or film-like substrate layers laminated together. Suitable materials for the lid label 2 include, for example, PET, biaxially oriented polypropylene (OPP), blends thereof, or synthetic paper. In the following description, in the thickness direction of the lid label 2, the side that is attached to the packaging bag 1 is referred to as the back surface, and the side that is exposed to the outside when the lid label 2 is closed is referred to as the front surface. A printed layer for realizing a desired design is formed on the front surface of the lid label 2, and a protective layer covering the printed layer may also be formed. The protective layer can be suitably formed by printing with varnish or the like, but the printed layer and protective layer are not essential to the present invention and may not be provided. A vapor-deposited layer, such as silver, is formed on the back surface of the lid label 2. A first adhesive portion 221 and a second adhesive portion 28 for attaching to the packaging bag 1 are formed on the back surface of the vapor-deposited layer.
[0016] Figure 3 is a top view of the lid label 2. The lid label 2 includes a lid portion 23, a support portion 22, a first cut line 24, a first sub-cut line 25, and a grip portion 21. When the support portion 22 of the lid label 2 is attached to the packaging bag 1 and the user pinches and lifts the grip portion 21 upward, the lid portion 23 is peelable from the packaging bag 1 so as to be reattachable, and the access opening 11 is exposed. When the lid portion 23 is closed, the second attachment portion 28 is attached to the packaging bag 1 to seal the access opening 11.
[0017] In the following description, the direction in which the lid portion 23 opens (the direction of arrow D in FIG. 3) is referred to as the peeling direction. The direction orthogonal to the peeling direction D is referred to as the width direction W. The support portion 22, the lid portion 23, and the grip portion 21 are provided side by side in this order in the peeling direction. The side of the grip portion 21 in the peeling direction D of the lid label 2 may be referred to as the peeling proximal side, and similarly, the support portion 22 side may be referred to as the peeling distal side.
[0018] On the back side of the lid label 2, a first attachment portion 221 and a second attachment portion 28 are provided. The second attachment portion 28 is a known re-peelable adhesive layer (adhesive portion). By joining the adhesive layer to the packaging bag 1, the lid label 2 is attached so as to cover the access opening 11. The first attachment portion 221 is composed of an adhesive for attaching the support portion 22 to the packaging bag 1. The adhesive strength of the first attachment portion 221 is greater than the adhesive strength of the second attachment portion 28. The first attachment portion 221 and the second attachment portion 28 include, for example, a configuration in which an adhesive is individually provided on the back surface of the lid label 2, and a configuration in which an adhesive layer on which the first attachment portion and the second attachment portion are formed is laminated on the back surface of the lid label 2.
[0019] The lid portion 23 has a larger area than the dispensing opening 11 and has a shape that closes the dispensing opening 11. In this embodiment, the lid portion 23 is approximately rectangular in plan view. A second adhesive portion 28 is provided on the edge of the back surface of the lid portion 23. No adhesive layer is provided on the back surface of the lid portion 23 inside the second adhesive portion 28. For example, the back surface of the lid portion 23 is subjected to an adhesive-killing treatment (not shown) by a mesh or dot pattern printing of an adhesive-killing agent, and the back surface of the lid portion 23 is a region with low peel strength. The density of the mesh or dot pattern printing on the lid portion 23 is determined by the set peel strength. Alternatively, the back surface of the lid portion 23 may be configured without an adhesive layer.
[0020] The support portion 22 is attached to the packaging bag 1 by a first adhesive portion 221 provided on its back surface. The support portion 22 is connected to a connecting end portion 232 located on the peeling distal side of the lid portion 23.
[0021] The first notch line 24 is a notch formed at the boundary between the lid portion 23 and the support portion 22. As shown in Figure 3, the first notch line 24 in this embodiment is formed in a straight line extending in a direction perpendicular to the peeling direction D of the substantially rectangular lid portion (width direction). The first notch line 24 penetrates in the thickness direction of the lid label 2. First secondary notches 25 (secondary notches) are formed continuously at both ends of the first notch line 24 in the width direction. The first secondary notches 25 are notches that extend from both ends of the first notch line 24 in the width direction W toward the peeling distal side and are folded back, having an arc shape. The first secondary notches 25 are formed to penetrate in the thickness direction of the lid label 2. The first secondary notches 25 prevent a tear from occurring on the extension of the first notch line 24 when the lid portion 23 is peeled and lifted.
[0022] A second notch line 26 is formed in the support portion 22. The second notch line 26 is provided between the secondary notch line 25 and the end of the support portion 22 in the width direction W. The second notch line 26 is provided alongside the first notch line 24 in the width direction W. The second notch line 26 and the first secondary notch line 25 are spaced apart.
[0023] The second cut line 26 includes an arc portion 263 and a pair of straight portions 261. In a plan view, the arc portion 263 has a convex arc shape toward the proximal side (lid portion 23 side) of the peeling direction D. The pair of straight portions 261 have a pair of straight shapes extending in the peeling direction D from the proximal end of the arc portion 263 in the peeling direction D. The second cut line 26 is formed to penetrate in the thickness direction of the lid label 2. A second secondary cut line 262 is formed at the distal end of the pair of straight portions 261 in the peeling direction D. The second secondary cut line 262 is folded back toward the first cut line 24 side from the distal end of the straight portion 261 in the peeling direction D and has a convex arc shape toward the distal side of the peeling direction D in a plan view. The second secondary cut line 262 prevents a tear from occurring on the extension of the straight portion 261 when the lid portion 23 is peeled and lifted. In the illustrated example, of the pair of second secondary cut lines 262, the second secondary cut line 262a located on the inside in the width direction W is formed in a position adjacent to the first secondary cut line 25. In other words, the first secondary cut line 25 and the inner second secondary cut line 262a are provided in a position where their positions in the peeling direction D overlap.
[0024] The gripping portion 21 is connected to the proximal end 231 of the lid portion 23 on the side where peeling is proximal. The gripping portion 21 is a part that the user can grip when opening and closing the lid portion 23. In this embodiment, it has a substantially triangular shape with the central part in the width direction W protruding towards the side where peeling is proximal. At least the edge of the gripping portion 21 has a convex portion 212 that protrudes on the surface side of the back surface of the lid portion 23. The convex portion 212 is pressed in the thickness direction of the lid label 2 and protrudes above the lid portion 23. In other words, it protrudes such that the back surface of the convex portion 212 is higher than the back surface of the lid portion 23. The convex portion 212 is spaced apart from one surface (adhesion surface) of the lid label 2.
[0025] When manufacturing the packaging container 10, a lid label 2 is attached so as to cover the opening 11 formed in the packaging bag 1. In the laminated film forming the packaging bag 1, an incision is made in the shape of the opening 11 from the back side where the lid label 2 is not attached to form the opening 11. Next, the laminated film of the packaging bag 1 and another laminated film where the lid label 2 is not attached are joined together, and the contents are placed inside and sealed to complete the packaging bag 1. Alternatively, instead of using two laminated films, the packaging bag may be formed by joining the ends of a single laminated film to form a roughly cylindrical shape.
[0026] Next, the usage of the packaging container 10 will be described. When removing the contents from the packaging container 10, the user grasps the grip portion 21 with their hand and lifts it, moving the grip portion 21 in the peeling direction D to peel off the lid portion 23 and lift it up. Generally, since the lid seal is in the shape of a thin sheet, it adheres to the packaging bag 1 without any gaps. However, in this embodiment, the packaging container 10 has a convex portion 212 on the grip portion 21, so as shown in Figure 2, a gap is created between the packaging bag 1 and the grip portion 21. Therefore, the user can easily grasp the grip portion 21 and open the lid portion 23. Furthermore, because the gap is formed by the convex portion 212, the grip portion 21 can be easily peeled back by, for example, inserting a finger between the pinch end 211 and the packaging bag 1 with one hand, and the pinch end 211 can be easily grasped.
[0027] Figure 4 is a perspective view showing the usage of the packaging container 10. As shown in Figure 4, when the lid 23 is peeled off and the dispensing opening 11 is opened, the lid 23 stands up, leaving the support portion 22 in place. When the lid 23 stands up, an opening 241 (discontinuous portion) opens between the lid 23 and the support portion 22 along the first notch line 24. The portion 242 distal to the first notch line 24 remains attached to the packaging bag 1 as the support portion 22. Similarly, when the lid 23 is peeled off and the dispensing opening 11 is opened, an opening 265 (discontinuous portion) opens between the lid 23 and the support portion 22 along the second notch line 26. The portion 264 distal to the second notch line 26 remains attached to the packaging bag 1 as the support portion 22. As a result, when the lid portion 23 is raised, the first notch line 24 and the second notch line 26 open, reducing the area of the connection between the support portion 22 and the lid portion 23, decreasing the rigidity of the boundary between the support portion 22 and the lid portion 23, and holding the connection portion in a bent state. As a result, the lid portion 23 is prevented from naturally falling towards the dispensing opening 11. The lid label 2 is peelable and reattachable to the packaging bag 1, and when the lid portion 23 is manually tilted towards the dispensing opening 11, the second adhesive portion 28 is reattached to the packaging bag 1 with the dispensing opening 11 closed, thereby sealing the dispensing opening 11.
[0028] According to the packaging container 10 of this embodiment, it is possible to provide a lid label 2 that is easy to manufacture, easy to open, and difficult to close once opened, as well as the packaging container 10.
[0029] (Second embodiment) A second embodiment of the present invention will be described with reference to Figures 5 to 8. In the following description, components that are common to those already described will be denoted by the same reference numerals, and redundant descriptions will be omitted.
[0030] Figure 5 is a plan view showing the lid label 2 of this embodiment. The lid label 2 of this embodiment is an example in which the lid label 2 of the first embodiment is further equipped with a riser guide portion 27. The riser guide portion 27 is formed as a recess from the surface to the back surface of the lid label 2 and is a guide that prevents the lid portion 23 from naturally falling towards the dispensing opening 11. The riser guide portion 27 is located between the end of the support portion 22 and the secondary cut line 25 in the width direction W (the direction in which the first cut line 24 extends) and is formed to extend in a direction along the first cut line 24. In other words, the riser guide portion 27 extends in a direction substantially perpendicular to the peeling direction D. The riser guide portion 27 is provided to prevent the lid portion 23 from naturally falling towards the dispensing opening 11.
[0031] Figure 6 is a schematic plan view showing the lid label 2 attached to the release paper 5. Figure 7 is a cross-sectional view AA of Figure 6, and Figure 8 is a cross-sectional view BB of Figure 6. As shown in Figure 6, the molded lid label 2 is temporarily attached to the release paper 5.
[0032] In manufacturing the lid label 2, for example, a vapor-deposited layer is formed on the back surface of a substrate on which the desired print has been applied to the surface, and a first adhesive portion 221 and a second adhesive portion 28 are provided on the back surface of the vapor-deposited layer. Before molding, the lid label 2 does not have an adhesive layer in the part corresponding to the edge including the grip portion 21. The substrate for the lid label 2 is temporarily attached to the release paper 5. In this state, multiple lid labels are prepared by punching out the parts other than the release paper 5, including the printed portion, into the shape of the lid label 2 and removing the waste. Subsequently, the first cut line 24, the first secondary cut line 25, the second cut line 26, and the second secondary cut line 262 are punched out in the shape shown in Figure 5. The punching of each cut line 24, 25, 26, and 262 and the punching of multiple lid labels 2 may be performed simultaneously.
[0033] Next, the multiple unmolded lid labels 2 temporarily attached to the release paper 5 are subjected to a pressing process. The pressing process uses a convex fitting die having a protruding shape that conforms to the shape of the convex portion 212 of the gripping portion 21 and the shape of the riser guide portion 27, and a concave fitting die having a recess corresponding to the convex fitting die. The release paper 5 with the unmolded lid labels 2 temporarily attached is placed and sandwiched between the pair of fitting dies. The convex fitting die presses convexly from the back side of the release paper 5 toward the front side of the paper surface in Figure 6, molding a lid label 2 having a convex portion 212 in the thickness direction. In addition, a lid label 2 with a riser guide portion 27 is formed by pressing convexly from the front side of the lid label 2 toward the depth side in Figure 6. In other words, when viewed in cross-section, the molded lid label 2 is formed with an uneven shape as shown in Figure 7 when multiple lid labels 2 are temporarily attached to the release paper.
[0034] In other words, as shown in Figure 7 when viewed in cross-section, the cross-section in the peeling direction D passing through the riser guide portion 27 has a convex portion 212 and a riser guide portion 27 formed thereon. The convex portion 212 protrudes to the front side in the thickness direction (upper side in Figure 7). The riser guide portion 27 protrudes to the back side in the thickness direction (lower side in Figure 7). The surface of the riser guide portion 27 is linearly recessed toward the back side.
[0035] As shown in Figure 8, a convex portion 212 is formed in the cross-section in the peeling direction D passing through the thumb end 211, and the rising guide portion 27 is not formed. The convex portion 212 has a long length in the peeling direction D in the region including the thumb end 211. When the convex portion 212 is formed over a wide area in the region including the thumb end 211 in this way, a wide area can be secured where the user can insert their fingertips.
[0036] Multiple lid labels 2, temporarily attached to the release paper 5, are sequentially attached to the packaging bag 1. As described above, the convex portion 212 can be formed by a simple process of sandwiching the unmolded lid labels 2, which are temporarily attached to the release paper 5, in the thickness direction and pressing them with a fitting mold. The rising guide portion 27 can also be formed at the same time.
[0037] Similar to the lid label 2 of the first embodiment, the lid label 2 of this embodiment also has a convex portion 212 formed on the grip portion 21, creating a gap between the packaging bag 1 and the tab end 211, allowing the user to easily grasp the grip portion 21. Compared to conventional packaging containers where the grip portion is stuck to the packaging bag, the user can easily grasp the grip portion 21 with one hand. Furthermore, the lid label 2 of this embodiment is equipped with a lifting guide portion 27, which prevents the lid portion 23 from naturally falling towards the dispensing opening 11 when the packaging container 10 is used. That is, as shown in Figure 4, similar to the first embodiment, when the lid portion 23 is raised, the rigidity of the boundary portion between the lid portion 23 and the support portion 22 decreases, and the connecting portion is held in a bent state. Furthermore, since the lifting guide portion 27 is formed convexly toward the back side at the connection portion between the lid portion 23 and the support portion 22, a crease is formed at the connection portion when the lid portion 23 is raised. As a result, even if the user releases their hand after raising the lid 23, the lid 23 is less likely to return to the closing position. As a result, the lid 23 remains open, making it easier for the user to remove the contents. According to the lid label 2 of this embodiment, for example, a user holding an infant can easily grasp the tab 211 with one hand, and even if the user releases their hand after opening the lid 23, the lid 23 remains stably open, allowing the user to easily remove the contents with one hand while caring for the infant. Furthermore, the user can easily remove the contents repeatedly with one hand.
[0038] Although one embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the above embodiment. It is possible to change the combination of components, or to make various modifications or deletions to each component without departing from the spirit of the present invention. Some modifications are given below as examples, but these are not all, and other modifications are also possible. Two or more of these changes may be combined as appropriate.
[0039] In this embodiment, the lid label 2 shows an example where the lid portion 23 and support portion 22 are substantially rectangular and the grip portion 21 is substantially triangular, but it is not limited to the illustrated example. For example, the shape of the lid label can be appropriately changed, such as by making a part of the periphery curved, taking into consideration design aesthetics.
[0040] In the above embodiment, an example of a straight-line shape for the riser guide portion 27 was shown, but the shape of the riser guide portion 27 is not limited to this, as long as a crease is formed at the connection point. For example, it may be wavy or zigzag in shape.
[0041] The first cut line 24 and the second cut line 26 are not continuous cuts, and a connection is provided between them. Therefore, the lid label 2 can maintain a connected state between the lid portion 23 and the support portion 22 between the first cut line 24 and the second cut line 26. However, this configuration is not essential. Even without the connection between the first cut line 24 and the second cut line 26, the support portion can maintain a continuous state as a single sheet.
[0042] The plan view shape of the lid portion 23 and support portion 22 of the lid label 2 according to the present invention is not limited to the rounded rectangle described above, but can be set as appropriate, such as a square or a circle. The gripping portion 21 is also not limited to the triangular shape in plan view as shown in the illustrated example, but may be an arc shape or a polygon shape. The gripping end 211 of the gripping portion 21 can be smoothly peeled off if it is provided along a line where the approximately center of the extension direction of the first insertion line 24 and the peeling direction D intersect at approximately a right angle, as in the embodiment described above, but the position of the gripping end is not limited to the above example. For example, it may be provided continuously on the edge of the lid portion 23 away from the support portion 22, and the lid portion 23 may be peeled off from a direction other than approximately a right angle to the first insertion line 24. Thus, the peeling direction D may intersect the first insertion line 24 from a direction other than approximately a right angle. Even if the lid is peeled off from a direction other than that substantially perpendicular to the first interlocking line 24, the presence of the rising guide portion 27 ensures that when the lid portion 23 is opened, the lid portion 23 remains stably bent and raised at the boundary between the support portion 22 and the lid portion 23.
[0043] The back surface of the lid portion 23, which is inside the second adhesive portion 28, may be formed to protrude slightly towards the surface side by pressing, similar to the convex portion 212 of the gripping portion 21. [Explanation of Symbols]
