Description

Technical Field

[0001] The present invention relates to a flap label.

Background Art

[0002] There is known a label (flap label) having an openable and closable flap-shaped lid that is attached so as to cover the outlet of a package containing contents. Here, when opening the lid of the flap label to take out the contents of the package, if the opened lid closes automatically due to elastic force or the like, for example, when only one hand can be used, the taking-out operation becomes difficult. Therefore, there is a need for a flap label (an over-stop type flap label) that can maintain the open state of the lid without external support when the lid is opened.

[0003] For example, in the over-stop type flap label disclosed in Patent Documents 1 and 2, in a flap having a two-layer structure composed of a lower layer and an upper layer, the lengths of the lower layer and the upper layer are made different, and the two are laminated with a shift to form a lid portion to be opened and closed into a two-layer structure and a fixing portion into a single-layer structure. Thereby, in the vicinity of the boundary between the single-layer portion and the multi-layer portion, the single-layer portion with weak elastic force serves as a hinge, so that the open state of the lid portion can be maintained.

[0004] On the other hand, when opening the flap-shaped lid, wrinkles and creases occur in the package, and if the lid is closed as it is, the outlet cannot be sealed. Therefore, when it is required to store the contents in a sealed state, it is desirable to be able to prevent wrinkles and creases in the package. In order to prevent wrinkles and creases in the package, there is known a flap label provided with a side frame for shape retention around the lid portion (for example, Patent Document 2).

Patent Document 1

[0006] However, if a side frame 3 is provided to a two-layer flap label 1, such as those disclosed in Patent Documents 1 and 2, the width of the single-layer fixing portion 22 becomes wider than the width of the lid portion 21 to match the width of the side frame 3. Therefore, there is a concern that if the flap 2 (lid portion 21) is opened forcefully, a cut along the width of the lid portion 21 may be made in the fixing portion 22, causing the fixing portion 22 to tear, resulting in damage to the flap 2 or detachment from the packaging 5 (see Figures 19 and 20).

[0007] The objective of the present invention is to suppress damage to the flap when opening a two-layer overstop type flap label with a side frame. [Means for solving the problem]

[0008] The flap label of the present invention is a flap label that is attached to a package having an opening for dispensing. The packaging comprises a flap that seals the opening so that it can be repeatedly opened and closed, and a side frame that is fixed to at least a portion of the area around the flap of the packaging. The aforementioned flap is A lid portion is attached to the packaging body in a removable and reattachable manner so as to close the aforementioned dispensing opening, The lid includes a fixing portion which is connected to a fold line, which is a dotted line indicating a part of the outer circumference of the lid that is folded when the flap is opened and closed, and which is fixed to the packaging body. The flap is composed of a stacked first layer and a second layer, the lid portion is a multilayer portion which is the part in which the first layer and the second layer are stacked, and the fixing portion includes a single layer which is the second layer in which the first layer is not stacked. The outer edge of the lid extends outward in the lateral direction toward the folding line, which is the length direction of the folding line of the flap in a plan view. [Effects of the Invention]

[0009] According to the present invention, in an overstop type flap label with a two-layer structure and a side frame, damage to the flap during opening can be suppressed. [Brief explanation of the drawing]

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or common parts are denoted by the same reference numerals. In this specification, the horizontal direction is the length direction of the folding line 21b of the flap 2 in plan view. The vertical direction is the direction orthogonal to the folding line 21b of the flap 2 in plan view.

[0012] [Embodiment 1] [Flap Label] The flap label of this embodiment will be mainly described with reference to FIGS. 1 to 5. The flap label 1 of this embodiment is a flap label attached to a package 5 having a take-out opening 50.

[0013] [Package] The package 5 is not particularly limited, and examples thereof include a bag body (such as pillow packaging) capable of storing contents such as goods, a box body, and the like.

[0014] The contents 6 stored inside the packaging 5 are not particularly limited, but examples include bundles of wet wipes (wet tissues) made by impregnating paper, woven fabric, nonwoven fabric, etc., with cosmetics, medicines, etc., in layers that can be freely dispensed one sheet at a time. However, the packaging 5 is not particularly limited, and can store a wide variety of contents that require airtight sealing, such as confectionery and food products.

[0015] The material of the packaging 5 is not particularly limited, but if the contents contain liquid, it is preferable that the material is highly liquid-tight (impermeable to moisture) or airtight. Furthermore, from the viewpoint of handling and portability, a thin and flexible film material is preferred. Such a film material can be fixed at the edges by heat sealing or the like to form a bag-shaped packaging 5. In this specification, "adhered" means that the material does not peel off the packaging 5 during normal use, and includes states where the material is constantly attached to the packaging 5 during normal use, such as with weak or strong adhesive.

[0016] (Flap label structure) The flap label 1 has a front surface 1a (the surface opposite to the back surface 1b) and a back surface 1b that can be attached to the packaging 5. When the flap label 1 is attached to the packaging 5 (attached state), the front surface 1a is the surface opposite to the packaging 5, and the back surface 1b is the surface facing the packaging 5 (see Figure 4).

[0017] The flap label 1 of this embodiment comprises a flap 2 and a side frame 3.

[0018] The flap 2 seals the dispensing opening 50 so that it can be repeatedly opened and closed. The flap 2 includes a lid portion 21 and a fixing portion 22.

[0019] The lid portion 21 (opening / closing portion) is a part that is detachably and reattachably attached to the packaging body 5 so as to close (cover) the dispensing opening 50. The fixing portion 22 is a part of the outer circumference of the lid portion 21 and is connected to the fold line 21b that is folded when the flap 2 is opened and closed, and is a part that is fixed to the packaging body 5. In other words, the lid portion 21 and the fixing portion 22 of the flap 2 are separated by a fold line 21b in a plan view (a plan view taken from a direction perpendicular to the main surface of the flap label 1). Note that the fold line 21b is not a clearly indicated line segment or anything like that, but rather a virtual line that is part of the outer circumference of the lid portion 21 and indicates the part that is folded when the flap 2 (lid portion 21) is opened and closed.

[0020] For example, a flap label 1 is attached to a package 5 containing contents 6 (such as wet wipes) such that the flap label 1 covers the opening 50 for removing the contents 6 from the package 5. The flap label 1 is attached to the package 5 in a way that allows it to be peeled off and reattached. After peeling off the flap label 21 to open the opening 50 of the package 5 and removing the contents 6, the opening 50 can be resealed by reattaching the flap label 21 around the opening 50 of the package 5. This allows the package 5 to be sealed, preventing, for example, the contents 6 remaining inside the package 5 from drying out.

[0021] The side frame 3 is fixed to at least a portion of the periphery of the flap 2 of the packaging body 5. That is, the side frame 3 is fixed to the packaging body 5 and remains on the packaging body 5 when the lid portion 21 is peeled off.

[0022] In this way, the side frame 3 is fixed to the packaging 5 both when peeling off and closing the lid 21. Therefore, the area around the opening 50 of the packaging 5 (including the area to which the lid 21 is attached) is reinforced by the presence of the side frame 3 and kept flat, making it less prone to wrinkles. This allows the packaging 5 to be sealed, preventing the contents 6, such as wet wipes remaining inside the packaging 5, from drying out. Furthermore, the opening and closing operation of the lid 21 (repeated peeling and sticking) is easy to operate. Additionally, since the side frame 3 is part of the flap label 1, no additional components are required other than the packaging 5 and flap label 1, thus avoiding increased complexity and costs in the manufacturing process.

[0023] Furthermore, in the flap label 1 shown in Figures 1 to 4, a notch is provided on the inside of the side frame 3 around the center of the tip of the lid 21 in order to make it easier to grasp the tip of the lid 21. The configuration for making the tip of the lid portion 21 easy to grasp is not limited to this, and for example, the tip of the lid portion 21 may be provided with a protruding part (grip portion) (not shown) for grasping when peeling. The grip portion may have, for example, a two-layer structure in which an upper layer and a lower layer are laminated, and the adhesive layer on the back surface 1b side of the lower layer is provided with an adhesive restraint to make it easy to grasp.

[0024] The flap 2 and the side frame 3 may be separate entities, or they may be connected in part and partially integrated. In the flap label 1 shown in Figures 1 to 4, the side frame 3 is separate from the flap 2 and is provided around a part of the outer peripheral edge 21a of the lid portion 21 of the flap 2, that is, around the lateral edge (side edge) and the longitudinal front edge, and is fixed to the packaging body 5.

[0025] In this embodiment, the flap 2 is composed of a stacked first layer 100 and a second layer 200.

[0026] The lid portion 21 consists of a multilayer portion in which the first layer 100 (lower lid layer 211) and the second layer 200 (upper lid layer 212) are stacked. The upper lid layer 212 is the portion enclosed by the cut line 212a and the fold line 21b of the second layer 200. The portion of the outer peripheral edge 21a of the lid 21 other than the fold line 21b is formed by the cut line 212a that forms the outer periphery of the upper lid layer 212 in the second layer 200 and the cut line 211a that forms the outer periphery of the lower lid layer 211 in the first layer 100 (see Figure 2). The notched line 212a may be an easily breakable line such as a perforation (an easily breakable line). In this case, the easily breakable line will be cut off when the lid 21 is first peeled off.

[0027] On the other hand, the fixing portion 22 includes a single-layer portion (a portion where the first layer 100 and the second layer 200 are not laminated) which is composed of the second layer 200 in which the first layer 100 is not laminated. In the flap label 1 shown in Figure 2, the fixing portion 22 consists of a single-layer portion composed only of the second layer 200.

[0028] Furthermore, in the flap label 1 shown in Figure 2, the side frame 3 has a two-layer structure consisting of a lower side frame layer 31 and an upper side frame layer 32. This two-layer structure increases the strength of the side frame 3, thereby more reliably suppressing the occurrence of wrinkles around the opening 50 of the packaging 5.

[0029] As shown in Figure 2, it is preferable that the second layer 200 is laminated on the front surface 1a side of the first layer 100. That is, when the front surface 1a side is considered to be the upper side, it is preferable that the first layer 100 is the lower layer and the second layer 200 is the upper layer. In this case, the portion consisting of the fold line 21b and its vicinity becomes more flexible, making it easier to open the flap 2 (lid portion 21), and making it less likely for the lid portion 21 to unintentionally return to its original position when open. This allows the lid portion 21 to maintain its open state without external support (see Figures 2 and 4). In particular, when the thickness of the first layer 100 is greater than that of the second layer 200, the difference in thickness between the lid portion 21, which includes the thick first layer 100 (lower lid layer 211), and the fixing portion 22, which consists of the thin second layer 200, becomes larger. As a result, the portion consisting of the fold line 21b and its vicinity becomes more flexible and functions as a hinge. Furthermore, since the side frame 3, which includes the thick first layer 100 (first side frame layer 31), has high strength, the effect of reinforcing the area around the opening 50 of the package 5 and keeping it in a flat state is fully realized.

[0030] In particular, when the thickness of the first layer is greater than that of the second layer, in other words, when the fixing portion 22 composed of the second layer is thin, it becomes easier to make cuts in the fixing portion 22 along the width of the lid portion 21, and the usefulness of the present invention is particularly high.

[0031] In the flap label 1 shown in Figure 2, the flap 2 (upper lid layer 212 and fixing part 22) and the side frame 3 are separated by a notch line 212a. It is preferable that the flap 2 and the side frame 3 are completely separated in this way. For example, if the flap 2 and the side frame 3 are connected in part (both ends of the folding line 21b) as shown in Figures 19 and 20, there is a possibility that a tear may occur starting from the adjacent part 21c of the outer edge 21a when the lid 21 is opened.

[0032] Furthermore, in the flap label 1 shown in Figure 2, for example, a strong adhesive layer (not shown) with relatively high adhesive strength is provided over the entire back surface 1b of the second layer 200, and a weak adhesive layer (not shown) with relatively low adhesive strength is provided over the entire back surface 1b of the first layer 100. In other words, since a weak adhesive layer is provided on the back surface 1b side of the lid portion 21 (lower lid layer 211) of the flap 2, the lid portion 21 can be peeled off and reattached to the packaging body 5. On the other hand, since a strong adhesive layer is provided on the back surface 1b side of the fixing portion 22 of the flap 2, the fixing portion 22 is firmly fixed to the packaging body 5. In this case, when the flap 2 (lid portion 21), which is weakly adhered to the packaging body 5, is opened forcefully, there is a concern that a cut along the width of the lid portion 21 may easily occur in the fixing portion 22, which is strongly adhered to the packaging body 5, causing the fixing portion 22 to tear and the flap 2 to be easily damaged. Therefore, the effects of the present invention are useful.

[0033] In this case, a weak adhesive layer will be provided on the back surface 1b of the side frame 3 (side frame first layer 31). Here, as shown in Figures 16 and 17, in the side frame 3, the portion of the side frame 3 other than the end opposite to the fold line 21b may be a multilayered portion 3b consisting of a laminated first side frame layer 31 and a second side frame layer 32, and at least a portion of the end of the side frame 3 opposite to the fold line 21b may be a single-layered portion 3c consisting of a second side frame layer 32 in which the first side frame layer 31 is not laminated. When a weak adhesive layer is provided on the back surface 1b of the first side frame layer 31 and a strong adhesive layer is provided on the back surface 1b of the second side frame layer 32 (i.e., when the second side frame layer 32 has higher adhesive strength than the first side frame layer 31), the single layer portion 3c is firmly fixed to the packaging body 5 because the second side frame layer 32, which has the strong adhesive layer, is attached to the packaging body 5. This prevents the side frame 3 from peeling off the packaging body 5 when opening the lid portion 21 of the flap 2, etc.

[0034] Furthermore, the two-layer structure of the flap label 1 is not limited to the form shown in Figure 2, but may also be the two-layer structure shown in Figure 18, for example. The flap label 1 shown in Figure 18 differs from the two-layer structure shown in Figure 2 in that the first layer 100 consists only of the lower lid layer 211 and does not have the lower side frame layer 31 (see Figure 2). In other words, the flap label 1 shown in Figure 18 has a single-layer structure in which the side frame 3 consists only of the second layer 200.

[0035] If the flap label 1 has the two-layer structure shown in Figure 18, a strong adhesive layer can be formed on the entire back surface 1b of the second layer 200 and a weak adhesive layer can be formed on the entire back surface 1b of the first layer 100, thereby forming a weak adhesive layer on the back surface 1b of the lid portion 21 of the flap 2 and a strong adhesive layer on the back surface 1b of the fixing portion 22 of the side frame 3 and the flap 2.

[0036] (Shape of the outer edge of the lid) In this embodiment, the outer peripheral edge 21a (side edge) of the lid portion 21 extends laterally outward toward the folding line 21b. As a result, the endpoint of the force applied when peeling off the lid portion 21 of the flap 2 is not linear but directed outward in the lateral direction, thus preventing tearing of the fixing portion 22 of the flap 2. Therefore, in the overstop type flap label 1 with a two-layer structure and a side frame 3, damage to the flap 2 during opening can be suppressed.

[0037] In Figures 1 to 4, the outer peripheral edge 21a of the lid portion 21 extends in the adjacent portion 21c adjacent to the fold line 21b in the shape of a quarter-circle arc, with its center located on the lateral side of the outer peripheral edge 21a and on the vertical side of the lid portion 21 relative to the fold line 21b. In this way, it is preferable that the outer edge 21a (side edge) of the lid portion 21 widens so that the degree of widening (inclination with respect to the vertical direction) gradually increases as it approaches the fold line 21b. In this case, it is possible to more reliably prevent tears from occurring in the fixing portion 22 of the flap 2. This is because if there is a part where the outer edge 21a of the lid portion 21 widens suddenly (the inclination with respect to the vertical direction suddenly increases), the force applied when peeling off the lid portion 21 may not be properly directed outward in the lateral direction, and a tear may occur in that part. Furthermore, the preferred shape of the widening portion of the outer peripheral edge 21a of the lid portion 21 is not limited to an arc shape, but also includes a curved tapered shape.

[0038] Preferably, the end of the outer peripheral edge 21a of the lid portion 21 on the side of the fold line 21b reaches the lateral end of the side frame 3. If the end of the outer peripheral edge 21a of the lid portion 21 on the side of the fold line 21b does not reach the lateral end of the side frame 3, then when opening the lid portion 21, a tear may occur in the fixing portion 22, starting from the adjacent portion 21c of the outer peripheral edge 21a, similar to the case where the flap 2 and the side frame 3 are partially connected as shown in Figures 19 and 20.

[0039] Furthermore, as shown in Figure 5, it is more preferable that the outer edge of the lid portion 21 widens laterally outward toward the fold line, such that the end of the outer edge 21a of the lid portion 21 on the side of the fold line 21b reaches the lateral end of the side frame 3 at the position of the fold line 21b in the vertical direction. However, as shown in Figure 6, the end of the outer peripheral edge 21a of the lid portion 21 on the side of the fold line 21b may extend laterally outward toward the fold line 21b, reaching the lateral end of the side frame 3 at a position further toward the lid portion 21 than the fold line 21b in the vertical direction. Even in this case, the same tear-suppressing effect as the flap label 1 shown in Figure 5 can be obtained. Furthermore, the configuration in Figure 5 is easier to bend and exhibits a more effective overstop function compared to the configuration in Figure 6, because the distance between the position of the vertical fold line 21b and the position where the outer edge of the lid 21 reaches the horizontal end of the side frame 3 is shorter. The overstop function is a function that maintains the open state of the lid even without external support when the lid is opened.

[0040] Referring to Figure 7, a non-adhesive portion 21d may be provided on the back surface 1b side of the lid portion 21 in an adjacent area adjacent to the fold line 21b. The non-adhesive portion 21d is a part that cannot be attached to the packaging body 5. If the outer edge 21a of the lid portion 21 widens at the adjacent portion 21c, this increases the resistance when peeling off the lid portion 21 in the adjacent region adjacent to the fold line 21b. By providing a non-adhesive portion 21d in the region where the resistance is high, the resistance can be reduced, and the lid portion 21 can be smoothly peeled off to the position of the fold line 21b where the overstop function is activated. As a result, the overstop function is activated more reliably, making it easier to remove the contents 6 from inside the packaging 5.

[0041] As a method for forming the non-adhesive portion 21d, for example, an adhesive layer may be provided on the entire surface of the back surface 1b of the lid portion 21 (lower lid layer 211), and a process may be performed to make the back surface 1b of the non-adhesive portion 21d unadhesive (for example, a process of laminating a mask layer (adhesive-suppressing layer) onto the adhesive layer) thereby making it impossible to adhere to it. Alternatively, the back surface 1b of the non-adhesive portion 21d may be made unadhesive by not providing an adhesive layer on the non-adhesive portion 21d.

[0042] For example, if the flap label 1 has a two-layer structure as shown in Figure 18, it may be difficult to provide a non-adhesive portion only in the adjacent area adjacent to the fold line 21b on the back surface 1b side of the lid portion 21 (lower lid layer 211) during the manufacturing process. In such cases, as shown in Figure 8, a non-adhesive portion 3a may be provided not only in the adjacent area adjacent to the fold line 21b of the lid portion 21, but also in the adjacent area adjacent to the fold line 21b of the side frame 3. However, if a non-adhesive portion is provided on the side frame 3, this non-adhesive portion may become the starting point for peeling of the side frame 3; therefore, it is preferable not to provide a non-adhesive portion on the side frame 3.

[0043] Furthermore, the non-adhesive portion 21d does not necessarily need to be provided over the entire lateral region adjacent to the fold line 21b of the lid portion 21. As shown in Figure 9, it may be provided only in the portion where the outer peripheral edge 21a of the lid portion 21 widens. Even in this case, the resistance when peeling off the lid portion 21 is not increased in the portion where the outer peripheral edge 21a of the lid portion 21 widens, so that the lid portion 21 can be smoothly peeled off to the position of the fold line 21b where the overstop function is exerted.

[0044] Referring to Figures 10 and 11, the portion of the fixing part 22 on the side of the fold line 21b may be composed of a single layer 221, and the portion of the fixing part 22 opposite to the fold line 21b may be composed of a multi-layer 222. In this case, the multi-layered portion 222 further reinforces the area around the opening 50 of the packaging 5, making it easier to maintain a flat state and further reducing the likelihood of wrinkles forming.

[0045] The ratio of the width (length in the vertical direction) of the multilayer portion 222 provided on the fixing portion 22 is not particularly limited, and the ratio of the width of the multilayer portion 222 may be increased as shown in Figure 12. In this case, the shape retention around the opening 50 of the packaging 5 is further improved, and the effect of making it even less prone to wrinkles is expected. Furthermore, the width of the multilayer portion 222 provided on the fixing portion 22 does not need to be constant; for example, as shown in Figure 13, the width of the central part in the horizontal direction may be narrowed. Even in this case, widening the width of the multilayer portion 222 at both ends in the horizontal direction can enhance the shape retention around the opening 50 of the packaging 5.

[0046] (Layer 1 and Layer 2) The first layer 100 and the second layer 200 may be, for example, a resin film. Examples of materials for resin films include polyethylene resins, polypropylene (PP) resins, cyclic olefin resins, polyolefin resins such as copolymer polymers containing polyethylene, polyester resins such as polyethylene terephthalate (PET), polyamide resins, polystyrene resins, and (meth)acrylic resins.

[0047] The thickness of the first layer 100 (lower layer) is not particularly limited, but is preferably 30 to 300 μm, and more preferably 50 to 100 μm. The thickness of the second layer 200 (upper layer) is not particularly limited, but is preferably 5 to 150 μm, and more preferably 10 to 50 μm.

[0048] On the front surface 1a (front surface 1a of flap label 1) of the second layer 200 (upper layer), a design layer formed from a printed layer or the like may be formed to enhance visibility and advertising effect as a POP label. Various characters and designs are formed on the printed layer. The printed layer can be formed by applying various inks suitable for the printing method to the front surface 1a of the second layer 200 and curing it. For example, ultraviolet-curing inks can be used as inks to form the printed layer.

[0049] An adhesive layer can be formed on the back surface 1b of each of the first layer 100 and the second layer 200 by applying an adhesive. The adhesive is not particularly limited, but for example, a UV-curing hot-melt adhesive (such as an acrylic adhesive) may be used.

[0050] (Packaging with flap label) According to this embodiment, a package with a flap label is provided, comprising a packaging body 5 and the flap label 1 described above (see Figure 1, etc.). The contents are stored in the packaging 5. The packaging 5 has an opening 50 for removing the contents 6.

[0051] [Embodiment 2] The flap label 1 of this embodiment is a flap label that is attached to a package 5 having an opening 50, It comprises a flap 2 that seals the dispensing opening 50 so that it can be repeatedly opened and closed, and a side frame 3 that is fixed to at least a portion of the periphery of the flap 2 of the packaging body 5, Flap 2 is, A lid portion 21 is attached to the packaging body 5 in a way that allows it to be peeled off and reattached, so as to close the dispensing opening 50, It includes a fixing portion 22 which is part of the outer circumference of the lid portion 21 and is connected to a fold line 21b that is bent when the flap 2 is opened and closed, and is fixed to the packaging body 5, Flap 2 is composed of stacked first layer 100 and second layer 200. The lid portion 21 consists of a multilayer portion in which the first layer 100 and the second layer 200 are stacked. The portion of the fixing part 22 on the side of the folding line 21b is composed of a single layer 221 which consists of a second layer 200 in which the first layer 100 is not laminated. The portion of the fixing part 22 opposite to the bend line 21b is composed of a multi-layered part 222.

[0052] In other words, the main feature of the flap label 1 of this embodiment is that only the portion of the fixing portion 22 on the side of the fold line 21b has a single-layer structure, while the portion of the fixing portion 22 opposite to the fold line 21b has a multi-layer structure. In this case, even if the single layer portion 221 of the fixing portion 22 tears, the thicker multi-layer portion 222 is less likely to tear, thus preventing the fixing portion 22 from tearing further. Furthermore, since the lid portion 21 that opens and closes is made of multiple layers, and the portion of the fixing portion 22 on the side of the fold line 21b is made of a single layer 221, the single layer 221 of the fixing portion 22, which has weak elasticity, acts as a hinge near the fold line 21b, thereby maintaining the open state of the lid and enabling the overstop function to be performed. Furthermore, by providing the multi-layered portion 222 in the area around the dispensing opening 50 of the packaging body 5 where the side frame 3 is not provided, the shape retention around the dispensing opening 50 of the packaging body 5 is further enhanced.

[0053] Furthermore, this embodiment aims to prevent the fixing portion 22 from tearing further even if a tear occurs in the single-layer portion 221 of the fixing portion 22. For this reason, in this embodiment, it is not necessary for the outer peripheral edge 21a of the lid portion 21 to spread laterally toward the folding line 21b, as in Embodiment 1. However, in this embodiment as well, the outer peripheral edge 21a of the lid portion 21 may extend laterally outward toward the folding line 21b (see Figure 10, etc.). In this case, the double tear prevention mechanism can more reliably suppress tearing of the fixing portion 22.

[0054] Referring to Figure 14, in this embodiment, assuming that the tearing will extend to the single-layer portion 221, a cut line 22a may be provided in the single-layer portion 221 to prevent the fixing portion 22 from tearing further by the multi-layer portion 222.

[0055] Referring to Figure 15, a tear-preventing portion 22b may be provided on the tip side of the cut line 22a of the single-layer portion 221. The tear-preventing portion 22b is not particularly limited as long as it is a part of the cut line 22a that has the effect of stopping the tear, but for example, a portion that is curved with respect to the main extension direction of the cut line 22a can be cited. Examples of such tear-preventing portions 22b include the hook-shaped portion, U-shaped portion, and circular portion shown in Figure 15. By providing the tear-preventing portion 22b, tearing of the fixing portion 22 can be suppressed even more reliably.

[0056] The present invention is not limited to the embodiments described above and can be modified in various ways. Two or more embodiments selected from the various embodiments described above may be combined as appropriate, or at least one configuration (part of a configuration) selected from the various embodiments described above may be replaced with a part of a configuration of another embodiment.
