Description

[Technical field]

[0001] The present invention relates to a paper open-close lid that opens and closes an outlet of a sanitary sheet package that stores disposable sanitary sheets used for sanitary purposes, and to a sanitary sheet package equipped with this open-close lid. [Background technology]

[0002] Disposable sanitary sheets used for sanitary purposes include, for example, disposable papers such as tissue paper, paper towels, toilet paper, and tissue paper. Conventionally, sanitary sheets have been provided as sanitary articles in which a plurality of sheets are laminated and stored in a packaging container. The sanitary sheet laminate, which is the content, is generally folded once to four times, and is embossed, coated with a chemical such as a moisturizing agent, printed, or the like, as necessary.

[0003] For example, dry-type tissue paper and moisturizing tissue paper in which various moisturizing ingredients have been added to dry-type tissue paper to enhance water retention and moist feeling and reduce irritation to the skin are provided in a packaging bag.

[0004] Wet tissues, which are sanitary sheets impregnated with a medicinal solution containing alcohol, moisturizer, surfactant, etc., into a fiber material such as paper, woven fabric, or nonwoven fabric, are stored in an airtight and water-impermeable packaging container to prevent drying. There are various types of sanitary sheets, such as wet tissues for wiping off dirt from the skin, makeup removers, baby bottom wipes, cleaning wipes, etc. These wet tissues are packaged in a flexible resin film that is airtight and water-impermeable to prevent the medicinal solution from drying, and are then manufactured into a product. When this type of containerized wet tissue is stored in a plastic container, it may be wound into a roll, but when it is stored in an enclosed bag, it may be used in which a large number of sheets (for example, about 20 to 100 sheets) are stacked by sequentially folding sheets cut into a rectangular shape in advance.

[0005] Generally, a package containing sanitary sheets is provided with an outlet that is closed by a lid member so that the sanitary sheets stored therein can be taken out from the outlet. The lid member is a lid label that can be peeled off and attached repeatedly and is made of a flexible sheet that is soft, airtight, and water-impermeable, such as a single material or a composite material of synthetic resins such as polyethylene terephthalate, polyethylene, polypropylene, polyester, polyamide, and polyvinyl chloride (see, for example, Patent Document 1).

[0006] In addition, when a film-like bag is used as a container for storing wet tissues, although it can be manufactured relatively inexpensively, it has the drawback that it has poor shape retention and looks bad when used as is. In recent years, a product has become known in which a bag containing a wet tissue laminate is further stored inside an exterior body.

[0007] In a wet tissue package in which an enclosed bag containing a wet tissue stack is further stored within an outer casing, the opening for removing the wet tissues stored in the enclosed bag via a removal opening is closed by an opening / closing lid made of a plastic molding material and can be opened and closed freely, and by opening the opening / closing lid, the wet tissues stored in the enclosed bag can be removed from the opening via the removal opening (see, for example, Patent Document 2).

[0008] Furthermore, a three-dimensional lid member has been proposed as a lid that can be attached to a wiping sheet removal port formed in a packaging body to hold a wiping sheet stored in the packaging body, the lid member having a base that is attached to the packaging body and a lid member that can open and close an opening formed in the base, the base and lid member being molded by pulp molding (see, for example, Patent Documents 3 and 4). [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Japanese Patent Application Publication No. 9-2547 [Patent Document 2] Patent No. 6412239 [Patent Document 3] Patent No. 6770787 [Patent Document 4] JP 2022-145352 A Summary of the Invention [Problem to be solved by the invention]

[0010] Lid labels made of synthetic resin film and opening / closing lids made of plastic moldings are formed using plastic materials, etc., which has the problem of going against efforts to address environmental issues. In addition, if measures to address environmental issues are made based on expensive biodegradable plastic materials, there is the problem that manufacturing costs increase.

[0011] Furthermore, the three-dimensional lid member formed using pulp molding can be manufactured using paper material regardless of the shape of the lid member, can ensure sufficient airtightness when the lid is closed, and is also strong and environmentally friendly. However, since the molding process is carried out with the pulp dispersed in water, it is necessary to perform the processes of dehydrating and drying the molded product, and has the disadvantage that the equipment required to adjust the concentration of the pulp slurry and to supply and discharge it is enormous.

[0012] In view of the above-described conventional situation, an object of the present invention is to provide a paper opening / closing lid that is formed into a flat plate shape using environmentally friendly paper-based material and can be easily and inexpensively manufactured, and a sanitary sheet packaging body equipped with this opening / closing lid.

[0013] Other objects of the present invention and specific advantages obtained by the present invention will become more apparent from the following description of the embodiments. [Means for solving the problem]

[0016] In the opening / closing lid of the present invention, the first adhesive layer region and the second adhesive layer region can be formed as continuous regions around the entire circumference by an adhesive layer having re-adhesive properties.

[0017] In addition, in the opening / closing lid of the present invention, the first adhesive layer region and the second adhesive layer region can be formed as discontinuous regions having their entire circumference divided into multiple parts by an adhesive layer having re-adhesive properties.

[0018] Furthermore, the opening / closing lid according to the present invention may be configured such that the base and the lid connected via the hinge are made of a single member made of the paper-based material.

[0019] In addition, the opening / closing lid of the present invention can be made of two components, the base and the lid, which are individually formed from the paper-based material, and the base and the lid are connected via a connecting film that serves as the hinge portion.

[0020] Furthermore, in the opening / closing lid of the present invention, an inner lid portion is formed together with the opening in the base by a cut line that is provided along the opening to leave a sealing point, and the base can have a third adhesive layer area for maintaining the inner lid portion in a closed state.

[0021] The present invention is a sanitary sheet packaging body, characterized in that any one of the opening and closing lids according to the present invention is affixed to the outlet of an enclosed bag which contains a sanitary sheet laminate in which multiple sanitary sheets are stacked.

[0022] The present invention also relates to a sanitary sheet packaging body, characterized in that any one of the opening and closing lids according to the present invention is affixed to the outlet of an outer casing that covers the outside of an enclosed bag that contains a sanitary sheet laminate in which multiple sanitary sheets are stacked together. Effect of the Invention

[0023] The opening / closing lid of the present invention comprises a base having an opening for removing the sanitary sheet stored in the packaging body via the removal port, and a lid connected to the base via a hinge portion and folded back via the hinge portion to be overlapped on the base, thereby closing the opening in an openable and closable manner.The lid is formed in a simple flat plate shape from an environmentally friendly paper-based material, and can be manufactured easily and inexpensively.

[0024] In addition, the opening and closing lid of the present invention has a first adhesive layer region formed on the base so as to surround the dispensing opening for the sanitary sheet, and for adhering the base to which the lid is connected via the hinge portion to the packaging body, and a second adhesive layer region formed on one of the opposing surfaces of the base and the lid which become opposing by folding back via the hinge portion so as to surround the opening, for holding the lid in a closed state, and the first adhesive layer region and the second adhesive layer region are made of adhesive layers having re-adhesive properties.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the present invention is not limited to the following examples, and can be modified as desired without departing from the gist of the present invention.

[0028] First, the configuration of one embodiment of an opening / closing lid according to the present invention and a sanitary sheet packaging body including the opening / closing lid will be described with reference to the drawings.

[0029] 1(A) and (B) are views showing a state in which the lid portion 30 of the opening / closing lid 10 according to one embodiment of the present invention is opened 180°, where (A) is a plan view of the opening / closing lid 10 and (B) is a bottom view of the opening / closing lid 10, and Fig. 2 is a perspective view of the sanitary sheet package 100 in a closed state in which the opening / closing lid 10 is attached to the outlet of an enclosed bag 110. Fig. 3 is a perspective view of the sanitary sheet package 100 showing a state in which the opening / closing lid 10 is opened, and Fig. 4 is a perspective view of the sanitary sheet package 100 showing a state in which a sanitary sheet 111 is taken out of the opening 21 via the outlet 112 of the enclosed bag 110.

[0030] As shown in Figures 2 to 4, this opening / closing lid 10 is attached to a sanitary sheet packaging body 100 which stores therein a sanitary sheet laminate consisting of multiple laminated sanitary sheets 111, and covers an opening 112 for the sanitary sheets 111 in an openable and closable manner. The lid 10 comprises a base 20 having an opening 21 formed therein for removing the sanitary sheet 111 stored in the sanitary sheet packaging body 100 via the opening 112, and a lid 30 which is connected to the base 20 via a hinge portion 40 and is folded back via the hinge portion 40 to be superimposed on the base 20, thereby closing the opening 21 in an openable and closable manner.

[0031] In this opening / closing lid 10, the base 20 and the lid 30 connected via the hinge portion 40 are formed as a single flat member made of a paper-based material, and as shown in Figures 1(A) and (B) , a first adhesive layer area 22 for adhering the base 20 to which the lid 30 is connected via the hinge portion 40 to the packaging body 110 is formed on the bottom side of the base 20 so as to surround the removal opening 112 of the sanitary sheet 111, and a second adhesive layer area 31 for holding the lid 30 in a closed state when it is folded back via the hinge portion 40 to face the base 20 is formed on the bottom side of the lid 30 so as to surround the opening 21.

[0032] The first adhesive layer region 22 and the second adhesive layer region 31 are each formed as a continuous adhesive layer region over the entire periphery by a re-adhesive adhesive layer, for example, a re-adhesive hot melt adhesive layer. Hot melt adhesives do not require a drying process, have a fast adhesion speed, and do not contain volatile organic compounds (VOCs), which are substances that cause photochemical air pollution, so they are known as highly safe and environmentally friendly adhesives.

[0033] Furthermore, since this opening / closing lid 10 has a second adhesive layer region 31 provided on the bottom side of the base 20, the base 20 to which the lid portion 30 is connected via the hinge portion 40 can be attached to an enclosed bag 110 that stores a sanitary sheet laminate in which multiple sanitary sheets 111 are stacked, as in the sanitary sheet packaging body 100 shown in Figure 2, and by folding back via the hinge portion 40, the lid portion 30 is overlapped on the base 20, allowing the opening 21 to be closed and opened freely.

[0034] The opening / closing lid 10 includes the base 20 in which the opening 21 is formed, and the lid 30, which is folded back at the hinge 40 to overlap the base 20 and close the opening 21 freely, and is formed as a single simple flat plate-like member from an environmentally friendly paper-based material, so that it can be easily and inexpensively manufactured. 2 ~500g / m 2 It is provided as a paper opening and closing lid made of paper with a waterproof film of about 7 μm to 50 μm attached to both sides or coated with a waterproof resin layer of about 3 μm to 50 μm.

[0035] This sanitary sheet packaging body 100 is stored as a sheet-type laminate in which a number of sanitary sheets 111 are stacked inside an enclosed bag 110 made of a film material, which is a flexible sheet having airtightness and water impermeability. Furthermore, an outlet 112 for taking out the sanitary sheets 111 is formed in the approximate center of one side of the enclosed bag 110 of the sanitary sheet packaging body 100, and a plastic flap label 115 is attached so as to cover the outlet 112. The opening and closing lid 10 is then adhered so as to cover the outlet 112 to which the flap label 115 is attached.

[0036] The lid portion 30 has a second adhesive layer area 31 provided on the bottom side, so that by folding it back via the hinge portion 40, it can be superimposed on the base portion 20 and keep the opening 21 closed so as to be freely opened and closed.

[0037] The sanitary sheet packaging body 100, which is formed by adhering the opening / closing lid 10 to an enclosed bag 110, can be opened by lifting the lid body 30 with a finger hook 32 provided on the opposite side of the outer periphery of the lid body 30 from the hinge portion 40, as shown in Figure 3.

[0038] A user of this sanitary sheet package 100 can take out the sanitary sheet 111 stored in the enclosed bag 110 from the opening 21 via the take-out opening 112, as shown in FIG.

[0039] The lid portion 30 can be folded back via the hinge portion 40 to overlap the base portion 20 and return the opening portion 21 to a closed state so as to be freely opened and closed.

[0040] In the lid portion 30, as described above, the first adhesive layer region 22 formed by the hot melt adhesive layer having re-adhesive properties as a continuous adhesive layer region over the entire circumference so as to surround the removal opening 112 of the sanitary sheet 111 can reliably attach the base portion 20 to which the lid portion 30 is connected via the hinge portion 40 to the enclosed bag 110 which stores therein a sanitary sheet laminate in which a plurality of sanitary sheets 111 are laminated, without creating any gaps. Furthermore, the second adhesive layer region 31 formed by the hot melt adhesive layer having re-adhesive properties as a continuous adhesive layer region over the entire circumference so as to surround the opening 21 for removing the sanitary sheet 111 stored in the enclosed bag 110 via the removal opening 112 can reliably attach the lid portion 30, which is opposed to the base portion 20 by folding it back via the hinge portion 40, to the base portion 20 without creating any gaps. The first adhesive layer region 22 does not need to be attached to the sanitary sheet packaging 100 immediately after applying the hot melt, and can be attached using various processes and methods. The hot melt in the second adhesive layer region 31 does not require processing such as pressing the paper sheet, making it easy to open and close the lid portion 30, and the close contact of the hot melt in the second adhesive layer region 31 can improve the airtightness.

[0041] Therefore, the sanitary sheet packaging body 100 formed by adhering the opening / closing lid 10 to the enclosed bag 110 can achieve high airtightness by closing the lid portion 30, making it suitable for storing a wet-type sanitary sheet 111 in the enclosed bag 110.

[0042] Here, the above-mentioned enclosed bag 110 is assumed to contain a sheet-type laminate of sanitary sheets 111, but the laminate of sanitary sheets 111 does not have to be sheet-type, and the enclosed bag may contain a so-called pop-up type sanitary sheet laminate.

[0043] Furthermore, in the above-mentioned sanitary sheet packaging body 100, the opening / closing lid 10 is adhered to the removal opening 112 of the enclosed bag 110 which stores a laminate of sanitary sheets 111 inside, but the above-mentioned opening / closing lid 10 may also be adhered to the removal opening 152 of an outer casing 151 which covers the outside of the enclosed bag 110 which stores a laminate of sanitary sheets 111 inside, as in the sanitary sheet packaging body 150 shown in Figure 5.

[0044] FIG. 5 is a perspective view showing a sanitary sheet package 150 in which the opening / closing lid 10 is adhered to the outlet 152 of the exterior body 151 in an open state.

[0045] In this sanitary sheet packaging body 150, the outer casing 151 has a main body formed of a paper box having a capacity capable of accommodating an enclosed bag 110 containing a laminate of sanitary sheets 111 inside, and the removal opening 152 for removing the sanitary sheet 111 from the enclosed bag 110 is blocked by the opening / closing lid 10 which is adhered to the removal opening 152 and can be opened and closed freely.

[0046] In this sanitary sheet packaging body 150, a number of sanitary sheets 111 are stored inside the enclosed bag 110, the outside of which is covered by the outer body 151, as a pop-up or sheet-type stack, and the sanitary sheets 111 stored in the enclosed bag 110 inside the outer body 151 can be removed from the opening 21 via the removal opening 112 by opening the outer lid 30 of the opening / closing lid 10 and peeling off the plastic flap label 115.

[0047] The lid portion 30 can be folded back via the hinge portion 40 to overlap the base portion 20 and return the opening portion 21 to a closed state so as to be freely opened and closed.

[0048] Here, in the opening / closing lid 10, a second adhesive layer region 31 for maintaining the lid portion 30 in a closed state is provided on the bottom side of the lid portion 30 so as to surround the opening 21 of the base portion 20. However, the second adhesive layer region 31 for maintaining the lid portion 30 in a closed state only needs to be provided on one of the opposing surfaces of the base portion 20 and the lid portion 30 which are folded back via the hinge portion 40 to be in an opposing state, and may also be provided on the top side of the base portion 20 so as to surround the opening 21, as in the opening / closing lid 10A shown in Figures 6 (A) and (B).

[0049] Figures 6 (A) and (B) show the state in which the cover portion 30 of the opening / closing lid 10A according to another embodiment of the present invention is opened 180 degrees, where (A) is a plan view of the opening / closing lid 10A and (B) is a bottom view of the opening / closing lid 10A.

[0050] In this opening / closing cover 10A, the same components as those in the opening / closing cover 10 described above are given the same reference numerals in the drawings, and detailed explanations thereof will be omitted.

[0051] This opening / closing lid 10A is the same as the opening / closing lid 10, except that the second adhesive layer area 31 for keeping the lid portion 30 in a closed state is provided on the upper side of the base 20, rather than on the bottom side of the lid portion 30, so as to surround the opening 21 of the base 20. As with the opening / closing lid 10, the base 20 to which the lid portion 30 is connected via a hinge portion 40 can be attached to an enclosed bag 110 which stores therein a sanitary sheet laminate in which multiple sanitary sheets 111 are laminated, and by folding back via the hinge portion 40, the lid portion 30 is superimposed on the base 20, so that the opening 21 can be closed and opened freely.

[0052] This opening / closing lid 10A also has a first adhesive layer area 22 and a second adhesive layer area 31, each formed as a continuous adhesive layer area around the entire circumference using a re-adhesive hot melt adhesive layer, so that by attaching it to the enclosed bag 110 and closing the lid portion 30, high airtightness can be obtained, and a sanitary sheet packaging body 100 suitable for storing a wet-type sanitary sheet 111 in the enclosed bag 110 can be provided.

[0053] Here, in the opening / closing lids 10, 10A, the opening 21 for removing the sanitary sheet 111 stored in the enclosed bag 110 via the removal opening 112, and the lid portion 30 which is connected to the base 20 via the hinge portion 40 and is folded back via the hinge portion 40 to be overlapped on the base 20, thereby closing the opening 21 so as to be freely opened and closed, are formed as a single simple flat-plate-shaped member from an environmentally friendly paper-based material, but may also be formed as two members, with the base 20 and the lid portion 30 individually formed from the paper-based material, as in the opening / closing lid 10B shown in Figures 7(A) and (B).

[0054] Figures 7(A) and (B) show the state in which the cover portion 30 of the opening / closing lid 10B according to another embodiment of the present invention is opened 180 degrees, where (A) is a plan view of the opening / closing lid 10B and (B) is a bottom view of the opening / closing lid 10A.

[0055] In this opening / closing cover 10B, the same components as those in the opening / closing covers 10 and 10A described above are given the same reference numerals in the drawings, and detailed explanations thereof will be omitted.

[0056] This opening / closing lid 10B is composed of two members, the base 20 and the lid 30, which are individually formed from the paper-based material, and the base 20 and the lid 30 are connected via a connecting film 40A that serves as the hinge portion 40. The connecting film 40A is It is a flexible ribbon-shaped resin film, and its long sides are adhesively fixed to the base portion 20 and the lid portion 30 .

[0057] This opening / closing lid 10B is the same as the opening / closing lids 10, 10A, except that the base 20 and the lid 30 are composed of two parts formed separately from the paper-based material, and the base 20 and the lid 30 are connected via a connecting film 40A that forms the hinge portion 40. Similar to the opening / closing lids 10, 10A, the base 20 to which the lid 30 is connected via the connecting film 40A that forms the hinge portion 40 can be attached to an enclosed bag 110 that stores a sanitary sheet laminate in which multiple sanitary sheets 111 are laminated, and by folding back via the connecting film 40A, the lid 30 is overlapped on the base 20, allowing the opening 21 to be closed and opened freely.

[0058] In the above-mentioned opening / closing lids 10, 10A, the first adhesive layer region 22 and the second adhesive layer region 31 are each formed as a continuous adhesive layer region around the entire periphery by a hot melt adhesive layer having re-adhesive properties, and the sanitary sheet package 100 formed by adhering the above-mentioned opening / closing lids 10, 10A to an enclosed bag 110 can obtain high airtightness by closing the lid portion 30. However, if the sanitary sheet package 100 is used for a package that stores a sanitary sheet laminate that does not require high airtightness, the first adhesive layer region 22 and the second adhesive layer region 31 may be formed as discontinuous adhesive layer regions 22A, 22B, 22C, 22D, 22E, 31A, 31B, 31C, 31D, 31E that are each divided into a plurality of discontinuous adhesive layer regions by a hot melt adhesive layer having re-adhesive properties, as in the opening / closing lid 10C shown in Figures 8(A) and (B) and the opening / closing lid 10D shown in Figures 9(A) and (B).

[0059] Figures 8 (A) and (B) show the state in which the lid portion 30 of the opening / closing lid 10C according to another embodiment of the present invention is opened 180 degrees, where (A) is a plan view of the opening / closing lid 10C and (B) is a bottom view of the opening / closing lid 10C.

[0060] This opening / closing lid 10C is the same as the above-mentioned opening / closing lids 10, 10A, except that the entire circumference is divided into multiple discontinuous first adhesive layer areas 22A, 22B, 22C, 22D and discontinuous second adhesive layer areas 31A, 31B, 31C, 31D by a re-adhesive hot melt adhesive layer, and the same components as the above-mentioned opening / closing lids 10, 10A are given the same symbols in the drawings and detailed descriptions thereof will be omitted.

[0061] Additionally, Figures 9(A) and (B) show a state in which the lid portion 30 of an opening / closing lid 10D according to another embodiment of the present invention is opened 180 degrees, where (A) is a plan view of the opening / closing lid 10C and (B) is a bottom view of the opening / closing lid 10D.

[0062] This opening / closing lid 10D is the same as the above-mentioned opening / closing lids 10, 10A, except that the entire circumference is divided into multiple discontinuous dot-shaped first adhesive layer areas 22E and dot-shaped second adhesive layer areas 31E, each of which is made of a re-adhesive hot melt adhesive layer.The same components as those of the above-mentioned opening / closing lids 10, 10A are given the same symbols in the drawings, and detailed descriptions thereof will be omitted.

[0063] These opening / closing lids 10C, 10D, like the opening / closing lids 10, 10A, 10B, have discontinuous adhesive layer regions 22A, 22B, 22C, 22D·31A, 31B, 31C, 31D that divide the entire circumference into multiple parts and dot-shaped adhesive layer regions 22E·31E, and the base 20 to which the lid portion 30 is connected via the hinge portion 40 can be attached to an enclosure bag 110 that stores a sanitary sheet laminate in which multiple sanitary sheets 111 are laminated. By folding back the lid portion 30 via the hinge portion 40, the lid portion 30 is overlapped on the base 20. Although high airtightness cannot be obtained even when the lid portion 30 is in a closed state, the opening 21 can be closed freely and opened, making them suitable for storing a dry type sanitary sheet 111 in the enclosure bag 110.

[0064] Since the adhesive layer regions 22A, 22B, 22C, 22D, 22E, 31A, 31B, 31C, 31D, 31E in the opening and closing lids 10C, 10D are discontinuous, the amount of re-adhesive hot melt adhesive used can be reduced.

[0065] In addition, the base 20 in the above-mentioned opening / closing lids 10, 10A, 10B, 10C, and 10D has an inner lid portion 23 formed together with the opening 21 by a cut line cut to leave a sealing point 24 along the opening 21, as in the opening / closing lid 10E shown in Figures 10(A) and (B), and may have a third adhesive layer region 26 for keeping the inner lid portion 23 in a closed state.

[0066] Fig. 10 (A) and (B) are views showing a state where the cover portion 30 of the opening / closing cover 10E according to one embodiment of the present invention is opened 180°, (A) is a plan view of the opening / closing cover 10, (B) is a bottom view of the opening / closing cover 10E, and Fig. 11 is a perspective view of the sanitary sheet package 100 in a closed state where the opening / closing cover 10E is attached to the outlet of the enclosed bag 110. Fig. 12 is a perspective view of the sanitary sheet package 100 showing a state where the opening / closing cover 10E is opened, Fig. 13 is a perspective view of the sanitary sheet package 100 in a state where the inner cover portion 23 formed together with the opening 21 in the base portion 20 of the opening / closing cover 10E has been removed, and Fig. 14 is a perspective view of the sanitary sheet package 100 showing a state where the sanitary sheet 111 is taken out of the opening 21 via the outlet 112 of the enclosed bag 110.

[0067] As shown in Figs. 10 to 14, this opening / closing lid 10E is attached to an enclosed bag 110 that houses a sanitary sheet laminate in which a plurality of sanitary sheets 111 are laminated, and opens and closes an outlet 112 for the sanitary sheets 111. The opening / closing lid 10E has a base 20 and a lid 30 that are folded back via a hinge 40 to face each other, and the base 20 and the lid 30 connected via the hinge 40 are formed as a single flat member from a paper-based material, for example, a material having a weight of 200 g / m 2 ~500g / m 2It is provided as a paper opening and closing lid made of paper with a waterproof film of about 7 μm to 50 μm attached to both sides or coated with a waterproof resin layer of about 3 μm to 50 μm.

[0068] As shown in (A) of Figure 10, the base 20 of this opening / closing lid 10E has an opening 21 for removing the sanitary sheet 111 stored in the enclosed bag 110 via the removal opening 112, along with an inner lid portion 23 that closes the opening 21, with a cut line cut along the opening 21 to leave a sealing point 24.

[0069] On the bottom side of the base 20, a first adhesive layer area 22 for attaching the base 20 to which the lid portion 30 is connected via the hinge portion 40 to the enclosed bag 110 is provided as a continuous adhesive layer area around the entire periphery surrounding the removal opening 112 of the sanitary sheet 111, as shown in (B) of Figure 10, using a sticky hot melt adhesive layer.

[0070] In addition, on the bottom side of the lid portion 30, a second adhesive layer region 31 for keeping the lid portion 30 in a closed state is provided as a continuous adhesive layer region around the entire periphery surrounding the opening 21 of the base portion 20, as shown in (A) of Figure 10, made of a hot melt adhesive layer having re-adhesive properties.

[0071] Furthermore, on the bottom side of the base 20, a third adhesive layer area 26 for keeping the inner lid portion 23 in a closed state is provided as a rectangular adhesive layer area within the area surrounded by the first adhesive layer area 22, as shown in (B) of Figure 10, made of a hot melt adhesive layer having re-adhesive properties.

[0072] That is, the first adhesive layer region 22, the second adhesive layer region 31, and the third adhesive layer region 26 in this opening / closing lid 10E are all made of hot melt adhesive layers having re-adhesiveness.

[0073] Furthermore, since this opening / closing lid 10E has a second adhesive layer region 31 and a third adhesive layer region 26 provided on the bottom side of the base 20, the base 20 to which the lid portion 30 is connected via the hinge portion 40 can be attached to an enclosed bag 110 that stores a sanitary sheet laminate in which multiple sanitary sheets 111 are laminated, as in the sanitary sheet packaging body 100A shown in Figure 11, and by folding back via the hinge portion 40, the lid portion 30 is overlapped on the base 20, allowing the opening 21 to be closed and opened freely.

[0074] The lid portion 30 has a second adhesive layer area 31 provided on the bottom side, so that by folding it back via the hinge portion 40, it can be superimposed on the base portion 20 and keep the opening 21 closed so as to be freely opened and closed.

[0075] The sanitary sheet packaging body 100A, in which the opening / closing lid 10E is attached to the enclosed bag 110, can be opened by pinching the finger hook portion 32 provided on the opposite side of the outer periphery of the lid body 30 from the hinge portion 40.

[0076] This sanitary sheet packaging body 100A has an inner lid portion 23 that closes the opening 21 together with the opening 21, formed by a cut line in the base 20 that appears when the lid body 30 is opened, which is cut so as to leave a sealing point 24 along the opening 21 as described above.Therefore, by visually confirming that the sealing point 24 remains, the user can confirm that the product is unopened and unused.

[0077] A user of this sanitary sheet packaging 100A can remove the inner lid portion 23 from the opening 21, as shown in Figure 13, by pinching and lifting the handle portion 23A of the inner lid portion 23 that closes the opening 21, and can remove the sanitary sheet 111 stored in the enclosed bag 110 from the opening 21 via the removal opening 112, as shown in Figure 14.

[0078] The inner lid portion 23 has a third adhesive layer area 26 provided on the bottom surface side, and therefore can be reattached to the opening 21 to close the opening 21.

[0079] In the sanitary sheet packaging 100A in which the opening 21 is closed by reattaching the inner lid portion 23 to the opening 21, the sealing point 24 is no longer remaining, so a user of this sanitary sheet packaging 100A can confirm that the package has been opened by visually confirming that the sealing point 24 is no longer remaining.

[0080] In other words, the inner lid portion 23 serves as a substitute for a plastic flap label that normally covers the dispensing opening for wet tissues, and in the sanitary sheet packaging 100A in which the opening / closing lid 10E is attached to the enclosed bag 110, there is no need to separately attach a plastic flap label 115 that covers the dispensing opening 112 as in the enclosed bag 110 in the sanitary sheet packaging 100, which is eco-friendly (reduced resin) and reduces costs.

[0081] The opening / closing lid 10E has an opening 21 for removing the sanitary sheet 111 stored in the enclosed bag 110 via the removal opening 112, and a lid portion 30 that is connected to the base 20 via a hinge portion 40 and is folded back via the hinge portion 40 to be overlapped on the base 20, thereby closing the opening 21 in an openable and closable manner.Since the lid portion 30 is formed as a single simple flat member from an environmentally friendly paper-based material, it can be manufactured easily and inexpensively.

[0082] In addition, the opening and closing lid 10E is provided with a first adhesive layer region 22 for attaching the base 20 to the enclosed bag 110 on the bottom side of the base 20 to which the lid 30 is connected via the hinge portion 40, the first adhesive layer region 22 surrounding the outlet 112 of the sanitary sheet 111, and a third adhesive layer region 26 for holding the inner lid 23 in a closed state as a rectangular region within the region surrounded by the first adhesive layer region 22. The second adhesive layer region 31 for keeping the lid portion 30 in a closed state is provided so as to surround the opening 21 of the base portion 20, and the first adhesive layer region 22, the second adhesive layer region 31, and the third adhesive layer region 26 are all made of hot melt adhesive layers having re-adhesiveness, and like the opening / closing lid 10, the first adhesive layer region 22 does not need to be attached to the sanitary sheet package 100A immediately after applying the hot melt, and attachment can be considered using various processes and methods. In addition, the hot melt of the second adhesive layer region 31 does not need to process the paper sheet by pressing or the like, making it easy to open and close the lid portion 30, and the close contact of the hot melt of the second adhesive layer region 31 can increase the airtightness.

[0083] As described above, in the opening / closing lid 10E, the first adhesive layer region 22 formed as a continuous adhesive layer region around the entire periphery so as to surround the removal opening 112 of the sanitary sheet 111 using a hot melt adhesive layer having re-adhesive properties can reliably attach the base 20 to which the lid portion 30 is connected via the hinge portion 40 to the enclosed bag 110 which stores a sanitary sheet laminate in which multiple sanitary sheets 111 are laminated, without any gaps. Furthermore, the second adhesive layer region 31 formed as a continuous adhesive layer region around the entire periphery so as to surround the opening 21 for removing the sanitary sheet 111 stored in the enclosed bag 110 via the removal opening 112 can reliably attach the lid portion 30, which is opposed to the base portion 20 by folding it back via the hinge portion 40, to the base portion 20 without any gaps.

[0084] Therefore, the sanitary sheet packaging body 100A formed by adhering the opening / closing lid 10E to the enclosed bag 110 can achieve high airtightness by closing the lid portion 30, making it suitable for storing a wet-type sanitary sheet 111 in the enclosed bag 110.

[0085] Here, in the opening / closing lid 10E, the first adhesive layer region 22 and the second adhesive layer region 31 are each formed as a continuous adhesive layer region over the entire periphery by a hot melt adhesive layer having re-adhesiveness, and the sanitary sheet package 100A obtained by adhering the opening / closing lid 10E to the enclosed bag 110 can obtain high airtightness by closing the lid portion 30. However, in the case of a dry-type sanitary sheet package that does not require high airtightness, If the adhesive layer 10 is used in a packaging material for storing a laminated sheet for packaging, the first adhesive layer region 22 and the second adhesive layer region 31 may be formed as discontinuous adhesive layer regions 22A, 22B, 22C, 22D, 22E, 31A, 31B, 31C, 31D, 31E each having a plurality of divided peripheries using a hot melt adhesive layer having re-adhesive properties, as in the opening / closing lid 10F shown in Figures 15(A) and (B) and the opening / closing lid 10G shown in Figures 16(A) and (B).

[0086] Figures 15 (A) and (B) show the state in which the lid portion 30 of an opening / closing lid 10F according to another embodiment of the present invention is opened 180 degrees, where (A) is a plan view of the opening / closing lid 10F and (B) is a bottom view of the opening / closing lid 10F.

[0087] This opening / closing lid 10F is the same as the above-mentioned opening / closing lid 10E, except that it has discontinuous first adhesive layer areas 22A, 22B, 22C, and 22D and discontinuous second adhesive layer areas 31A, 31B, 31C, and 31D, each of which is divided around its entire circumference into multiple areas by a re-adhesive hot melt adhesive layer.The same components as those of the above-mentioned opening / closing lid 10E are given the same symbols in the drawings, and detailed descriptions thereof will be omitted.

[0088] Additionally, (A) and (B) of Figure 16 are diagrams showing a state in which the cover portion 30 of an opening / closing lid 10G according to another embodiment of the present invention is opened 180 degrees, where (A) is a plan view of the opening / closing lid 10G and (B) is a bottom view of the opening / closing lid 10G.

[0089] This opening / closing lid 10D is the same as the above-mentioned opening / closing lid 10E, except that the first adhesive layer area 22E and the second adhesive layer area 31E are discontinuous dot-shaped areas, each of which is divided into multiple areas around its entire circumference using a re-adhesive hot melt adhesive layer.The same components as those of the above-mentioned opening / closing lid 10E are given the same symbols in the drawings, and detailed descriptions of them will be omitted.

[0090] These opening / closing lids 10F, 10G, like the opening / closing lid 10E, can be attached to the base 20 to which the lid part 30 is connected via the hinge part 40, to an enclosed bag 110 that stores a sanitary sheet laminate in which a plurality of sanitary sheets 111 are laminated, by using discontinuous adhesive layer areas 22A, 22B, 22C, 22D·31A, 31B, 31C, 31D that divide the entire circumference into multiple parts and dot-shaped adhesive layer areas 22E·31E. By folding back the lid part 30 via the hinge part 40, the lid part 30 is overlapped on the base 20. Although high airtightness cannot be obtained even when the lid part 30 is in a closed state, the opening 21 can be closed freely and is suitable for storing a dry type sanitary sheet 111 in the enclosed bag 110.

[0091] Since the adhesive layer regions 22A, 22B, 22C, 22D, 22E, 31A, 31B, 31C, 31D, 31E in the opening and closing lids 10F, 10G are discontinuous, the amount of re-adhesive hot melt adhesive used can be reduced.

[0092] Here, in the opening / closing lids 10E, 10F, and 10G, the two components of the lid portion 30 and the base portion 20, which are connected via a connecting film attached as the hinge portion 40, can also be formed individually from the paper-based material.

[0093] In the above-mentioned opening / closing lids 10, 10A to 10G, the first adhesive layer region 22, 22A to 22E, the second adhesive layer region 31, 31A to 31E, and the third adhesive layer region 26 are formed from a hot melt adhesive layer having re-adhesive properties, but the adhesive layer may also be made from an adhesive other than a hot melt adhesive, such as a cold glue adhesive or a silicone adhesive, having re-adhesive properties.
