Description

The present invention relates to an opening/closing 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 opening/closing lid.

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 moisturizer, printed, or the like, as necessary.

For example, dry-type tissue paper and moisturizing-type tissue paper that contains various moisturizing ingredients to improve water retention and moist feeling and reduce irritation to the skin are provided in a packed state.

Wet tissues, which are sanitary sheets impregnated with a drug 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 stored in a packaging body made of a flexible resin film that is airtight and water-impermeable to prevent the drug solution from drying out. In addition, when storing this type of containerized wet tissue in a plastic container, it may be wound into a roll, but when storing in an enclosed bag, it is used in which a large number of sheets (for example, about 20 to 100 sheets) are stacked after being cut into a rectangular shape in advance and folded in order. When a film-like enclosed bag is used as a container for storing wet tissues, it can be manufactured relatively inexpensively, but there are problems in that the shape retention of the bag itself is poor and it looks bad when used as is. In recent years, a package in which a sealed bag containing a laminate of wet tissues is further housed within an exterior body has become known (see, for example, Patent Documents 1 and 2).

It has also been proposed that an airtight paper container for storing a bag containing wet tissues or the like be provided with a storage hole for storing tweezers, so that the wet tissues can be removed cleanly from the bag without coming into contact with germs on the hands (see, for example, Patent Document 3).

Japanese Patent Application Publication No. 9-2547 Patent No. 6412239 JP 2011-37448 A

The technology disclosed in Patent Document 3 relates to an airtight paper sealed container for storing sealed bags containing wet tissues or the like, in which tweezers that can be stored in a storage hole formed in the lid are prepared as a separate part, and the product is shipped set in the paper sealed container. This requires the work of setting the tweezers, which are manufactured as a separate part, in the lid, which creates the problem of increased costs due to increased manufacturing and management labor required for the product.

In view of the above-mentioned conventional circumstances, an object of the present invention is to make it possible to ship a sanitary sheet package at reduced cost without the need for the operation of setting tweezers on the lid portion.

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.

In the present invention, tweezers molded from resin and integrally formed with the inner lid via a bridging portion are placed in the opening of the inner lid of the opening/closing lid, so that the user can remove the bridging portion to separate the tweezers from the inner lid and use them.

That is, the present invention provides an opening/closing lid that is molded from flexible resin and is attached to a packaging body that stores a sanitary sheet laminate in which multiple sanitary sheets are stacked together, and that covers an opening for dispensing the sanitary sheets in an openable and closable manner, the opening having an outer lid and an inner lid connected via a hinge portion, and tweezers that are placed in the opening of the inner lid and are molded from resin integrally with the inner lid via a bridging portion, and the tweezers can be separated from the inner lid and used by removing the bridging portion.

The opening/closing lid of the present invention can have at least one inner ring on the upper surface of the inner lid arranged to surround the opening, at least one inner ring on the lower surface of the outer lid that fits into the inner ring, and a finger hook portion provided on the outer periphery of the outer lid at a position opposite the hinge portion.

In addition, the opening/closing lid of the present invention has a tweezers holding portion provided on the underside of the outer lid and into which the tweezers are fitted, and the tweezers that have been separated from the inner lid by removing the bridging portion can be held removably on the underside by the tweezers holding portion, making it possible to open and close the opening of the inner lid with the outer lid.

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 adhered to the outlet of an enclosed bag which contains a sanitary sheet laminate in which multiple sanitary sheets are stacked.

The present invention can also be a sanitary sheet packaging body, in which any one of the opening/closing lids according to the present invention is adhered 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.

In the opening/closing lid according to the present invention, the tweezers placed in the opening of the inner lid can be separated from the inner lid and used by removing the bridge portion provided in the opening of the inner lid. The opening/closing lid is connected to the outer lid via a hinge portion, and the inner lid and the tweezers are integrally molded with each other through the bridge portion by resin, so there is no need to set the tweezers in the lid portion.

Therefore, by adhering the opening/closing lid of the present invention to the sanitary sheet removal opening of a sanitary sheet packaging body that stores a laminate of sanitary sheets inside, the sanitary sheet removal opening can be blocked so as to be freely opened and closed, and the sanitary sheet packaging body can be shipped at reduced costs without the need to set tweezers in the lid portion.

In other words, according to the present invention, an open-close lid having tweezers in the lid portion that openably covers the removal opening of a sanitary sheet package that stores disposable sanitary sheets used for sanitary purposes, and a sanitary sheet package including this open-close lid can be shipped without the need to set the tweezers in the lid portion, and since there is no need to manufacture and set the tweezers as a separate part, it is possible to provide an open-close lid and a sanitary sheet package including this open-close lid that achieves cost reduction.

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.

First, the configuration of one embodiment of the opening and closing lid according to the present invention will be described with reference to the drawings. Fig. 1 is a perspective view showing an open state of the outer lid 20 with tweezers 40 attached to the underside 20A of the opening and closing lid 50 according to one embodiment of the present invention. Figs. 2A, 2B, and 2C are views showing the opening and closing lid 50 in a state where the outer lid 20 is opened 180°, Fig. 2A is a plan view of the opening and closing lid 50, Fig. 2B is a bottom view of the cross-sectional arrow view of the opening and closing lid 50 along line A, and Fig. 2C is a bottom view of the opening and closing lid 50. Fig. 3 is a plan view of an opening and closing lid in which the number of bridges that integrate the tweezers with the inner lid is changed. Figs. 4A, 4B, and 4C are views showing the opening and closing lid 50 in a state where the outer lid 20 is closed, Fig. 4A is a plan view of the opening and closing lid 50, Fig. 4B is a front view of the opening and closing lid 50, and Fig. 4C is a bottom view of the opening and closing lid 50.

The opening/closing lid 50 has an inner lid 10 and an outer lid 20 that are integrally formed via a hinge portion 30, and is integrally molded from flexible resin.

2A, 2B, and 2C, the inner lid 10 has an opening 11, and further has tweezers 40 disposed at the opening 11 and integrally formed with the inner lid 10 via a bridging portion 12. The tweezers 40 can be separated from the inner lid 10 by removing the bridging portion 12.

In this opening/closing lid 50, the bridging portion 12 consists of four bridging portions 12a, 12b, 12c, and 12d, with the bridging portions 12a and 12b extending from the tip portions 40a and 40b of the tweezers 40 and the bridging portions 12c and 12d extending from the base portion 40c, but the number of bridging portions does not necessarily have to be four, and it is sufficient that the tweezers 40 be integrated with the inner lid 10 until the tweezers 40 are separated from the inner lid 10. The number of bridging portions integrating the tweezers 40 with the inner lid 10 may be changed to four-point holding, three-point holding (parts 1 to 4), two-point holding (parts 1 to 6), or one-point holding (parts 1 to 4), as illustrated in the plan views of the opening/closing lid 50 in FIG. 3, and at least one of the four bridging portions 12a, 12b, 12c, and 12d may be provided.

In addition, as shown in Figures 2A and 2B, the outer lid 20 has a tweezers holding portion 21 on the underside 20A, and as shown in Figure 1, the tweezers 40 separated from the inner lid 10 can be held by the tweezers holding portion 21, thereby allowing the tweezers 40 to be attached to the underside 20A.

In this opening/closing lid 50, the tweezers holding portion 21 consists of three tweezers holding portions 21a, 21b, 21c: two tweezers holding portions 21a, 21b formed as approximately V-shaped convex portions for clamping the tip portions 40a, 40b of the tweezers 40, and one tweezers holding portion 21c formed as an approximately C-shaped convex portion for fitting and supporting the base portion 40c.

Furthermore, the upper surface 10A of the inner lid 10 has an inner ring 13 arranged to surround the opening 11, and the lower surface 20A of the outer lid 20 has an inner ring 22 that fits into the inner ring 13, and a finger hook portion 23 is provided on the outer periphery of the outer lid 20 at a position opposite the hinge portion 30.

In this opening/closing lid 50, the inner ring 13 provided on the inner lid 10 consists of two inner rings 13A, 13B: an inner ring 13A on the inner side along the opening 11, and an inner ring 13B on the outer side along the outer edge of the inner lid 10.

In addition, the inner ring 22 provided on the outer lid 20 consists of three inner rings 22A, 22B, 22C: two inner rings 22A, 22B formed so that the inner ring 13A can be fitted into the gap, and one inner ring 22C formed so that the inner ring 13B can be fitted into.

Here, the inner ring 13A on the inner periphery of the inner lid 10 is formed around the entire circumference along the inner peripheral edge surrounding the opening 11, and the inner ring 13B on the outer periphery is formed along the outer peripheral edge of the inner lid 10, not around the entire circumference, except for the areas corresponding to the hinge portion 30 and the finger hook portion 23.

Furthermore, the inner ring 13A on the inner periphery side is provided with a locking portion 14 which is locked to an inner ring 22B provided on the outer lid 20 at a position corresponding to the finger hook portion 23.

It is sufficient that at least one each of the inner rings 13, 22 is formed in a closed loop. By increasing the number of them, the airtightness of the opening/closing lid 50 can be improved.

The hinge portion 30 that integrates the inner lid 10 and the outer lid 20 is formed to be thin, so that by folding the inner lid 10 and the outer lid 20, the opening 11 of the inner lid 10 can be blocked by the outer lid 20, as shown in Figures 4A, 4B, and 4C.

When the opening 11 of the inner lid 10 is closed by the outer lid 20, the opening/closing lid 50 can be opened by pinching the finger hook portion 23 located on the opposite side to the hinge portion 30.

In the closed state of the opening/closing lid 50 with the inner lid 10 and the outer lid 20 folded, the tweezers 16 arranged at the opening 11 of the inner lid 10 and formed integrally with the inner lid 10 via the four bridging portions 12a, 12b, 12c, and 12d are held by the tweezers holding portion 21 consisting of three tweezers holding portions 21a, 21b, and 21c provided on the underside 20A of the outer lid 20, as shown in FIG. 4C. When the four bridging portions 12a, 12b, 12c, and 12d are removed, the repulsive force in the expanding direction generated in the tweezers 40 attached to the tweezers holding portion 21 is received by the three tweezers holding portions 21a, 21b, and 21c, thereby enabling the tweezers 40 to be held by the tweezers holding portion 21.

This opening/closing lid 50 is arranged in the opening 11 of the inner lid 10, and the tweezers 40 formed integrally with the inner lid 10 via the bridging portion 12 can be separated from the inner lid 10 by removing the bridging portion 12. The separated tweezers 40 can be removably held on the underside 20A of the outer lid 20 by the tweezers holding portion 21. Since the inner lid 10, the outer lid 20 and the tweezers 40 are integrally molded from flexible resin, there is no need to set the tweezers 40 in the outer lid 20.

In other words, since the inner lid 10, outer lid 20 and tweezers 40 of this opening/closing lid 50 are integrally molded from flexible resin, there is no need to manufacture and set the tweezers as separate parts, and costs can be reduced by reducing the number of steps required to manufacture and manage the product.

Therefore, by adhering this opening/closing lid 50 to the sanitary sheet removal opening of a sanitary sheet packaging body which stores a laminate of sanitary sheets inside, the sanitary sheet removal opening can be freely opened and closed, and the sanitary sheet packaging body can be shipped at reduced costs without the need to set tweezers in the lid portion.

That is, this opening/closing lid 50 is adhered to the sanitary sheet removal opening of a sanitary sheet packaging body that stores a laminate of sanitary sheets inside, and closes the sanitary sheet removal opening in a manner that allows it to be opened and closed freely. For example, as in the sanitary sheet packaging body 100 shown in Figures 5, 6, 7 and 8, the opening/closing lid 50 is adhered to the removal opening 112 of an enclosed bag 110 that stores a laminate of disposable sanitary sheets 111 used for sanitary purposes inside.

FIG. 5 is a perspective view showing a sanitary sheet packaging body 100 according to one embodiment of the present invention, FIG. 6 is a perspective view of the unused sanitary sheet packaging body 100 showing the opening and closing lid 50 attached to the removal opening 112 of the enclosed bag 110 being opened, FIG. 7 is a perspective view of the sanitary sheet packaging body 100 showing the sanitary sheet 111 being grasped with tweezers 40 and removed from the removal opening 112 of the enclosed bag 110, and FIG. 8 is a perspective view of the sanitary sheet packaging body 100 showing the tweezers 40 being fitted and held in the tweezers holding portion 21 provided on the outer lid 20.

This sanitary sheet package 100 is stored as a sheet-type laminate in which multiple sheets are stacked inside an enclosure 110 made of a film material, which is a flexible sheet that is airtight and water impermeable. In addition, an outlet 112 for taking out the sanitary sheet 111 is formed in the approximate center of one side of the enclosure 110 of the sanitary sheet package 100, and the opening and closing lid 50 is adhered so as to cover the outlet 112.

The encapsulating bag 110 is made of a flexible sheet that is soft, airtight, and water impermeable, such as a single material or a composite material of synthetic resin, such as polyethylene, polypropylene, polyester, polyamide, polyvinyl chloride, etc. The encapsulating bag 110 is not limited to the above, and may be made of a composite material in which the above-mentioned synthetic resin is bonded to aluminum foil, paper, etc.

The enclosed bag 110 is a so-called pillow-type package in which one end of the long side and both ends of the short side of the film are sealed, and the sanitary sheet 111 is laminated and enclosed inside. Note that the enclosed bag 110 of the sanitary sheet package 100 is not limited to the so-called pillow type as described above, and may be of other types as long as it is made of a flexible sheet that is soft, airtight, and water-impermeable, and can store the sanitary sheet 111 such as wet tissue inside.

Here, the sanitary sheet 111 stored in the above-mentioned enclosed bag 110 is a wet-type sanitary sheet made by impregnating a fibrous material having wet strength, such as a nonwoven fabric made of pulp, cotton, synthetic fibers, etc., a paper made of natural pulp, synthetic pulp, etc., or a cloth such as gauze, with a liquid component or solution such as water, alcohol, fragrance, lotion, medicine, surfactant, etc. However, it may also be a dry-type sanitary sheet such as a dry-type tissue paper or a moisturizing type tissue paper in which various moisturizing ingredients are added to dry-type tissue paper to increase water retention and moist feeling and reduce irritation to the skin.

5, the sanitary sheet 111 is stored in a sealed bag 110 as a sheet-type laminate in which a large number of sheets are stacked. The sanitary sheet 111 stored in the sealed bag 110 as a sheet-type laminate can be taken out from an outlet 112 of the sealed bag 110.

An outlet 112 having both ends forming an arc is formed in the approximate center of one side of the enclosed bag 110 of the sanitary sheet package 100. The opening 11 of the inner lid 10 is formed larger than the outlet 112 at the outlet 112, and an opening/closing lid 50 is attached to the outer lid 20 to cover the outlet 112 in an openable/closable manner.

As described above, the opening/closing lid 50 is disposed in the opening 11 of the inner lid 10, and the tweezers 40 formed integrally with the inner lid 10 via the bridging portion 12 are integrally molded with the inner lid 10 and the outer lid 20 from a flexible resin, and in an unused sanitary sheet package 100, when a user opens the outer lid 20 connected to the inner lid 10 via the hinge portion 30, as shown in Fig. 6, the tweezers 40 formed integrally with the inner lid 10 via the bridging portion 12 in the opening 11 of the inner lid 10 can be visually confirmed, thereby making it possible to confirm that the sanitary sheet package 100 is unused. The tweezers 40 can be separated from the inner lid 10 by removing the bridging portion 12, and by visually confirming that the bridging portion 12 has been removed, it can be confirmed that the sanitary sheet package 100 is in use.

As shown in Figure 7, the sanitary sheets 111 stored in the sealed bag 110 of this sanitary sheet packaging body 100 can be grasped with the tweezers 40 separated from the inner lid 10 by removing the crosslinking portion 12, and removed one by one from the removal opening 112 of the sealed bag 110.This allows the sanitary sheets 111 to be removed cleanly from the sealed bag 110 without coming into contact with germs on the hands.

In addition, the tweezers 40 separated from the inner lid 10 by removing the bridging portion 12 can be detachably held by the tweezers holding portion 21 provided on the underside 20A of the outer lid 20, as shown in Figure 8, and can be stored in a clean condition.

In addition, when the sanitary sheet packaging body 100 is in use, as shown in FIG. 7, by opening the outer lid 20 of the opening/closing lid 50, the sanitary sheets 111 can be grasped with the tweezers 40 removed from the tweezers holding portion 21 and removed one by one from the removal opening 112 of the sealed bag 110, allowing the sanitary sheets 111 to be removed cleanly from the sealed bag 110 without coming into contact with germs on the hands.

Here, the above-mentioned sealed bag 110 is assumed to store a sheet-type laminate of sanitary sheets 111, but the laminate of sanitary sheets 111 does not have to be sheet-type, and even if the sealed bag contains a so-called pop-up type sanitary sheet laminate, the sanitary sheets 111 can be grasped with tweezers 40 removed from the above-mentioned tweezers holding portion 21 and removed one sheet at a time from the removal opening of the sealed bag.

In addition, in the above-mentioned sanitary sheet packaging body 100, the opening/closing lid 50 is adhered to the removal opening 112 of the enclosed bag 110 which stores the laminate of sanitary sheets 111 inside, but the above-mentioned opening/closing lid 50 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 the laminate of sanitary sheets 111 inside, as in the sanitary sheet packaging body 150 shown in Figure 9.

FIG. 9 is a perspective view showing a sanitary sheet package 150 in an open state, in which an opening/closing lid 50 is attached to a take-out opening 152 of an exterior body 151. As shown in FIG.

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 50 which is adhered to the removal opening 152 and can be opened and closed freely.

In this sanitary sheet packaging body 150, as shown in Figures 1 to 4A, 4B and 4C, the opening and closing lid 50 has the inner lid 10 and the outer lid 20 integrated via the hinge portion 30, the tweezers 40 arranged in the opening 11 of the inner lid 10 is integrated with the inner lid 10 via the bridging portion 12, a tweezers holding portion 21 that detachably holds the tweezers 40 that have been separated from the inner lid by removing the bridging portion 12 is provided on the underside 20A of the outer lid 20, the inner lid 10, the outer lid 20 and the tweezers 40 are integrally molded from a flexible resin, and the tweezers 40 can be separated from the inner lid 10 by removing the bridging portion 12, and as shown in Figure 9, the tweezers 40 that have been separated from the inner lid 10 can be detachably held on the underside 20A of the outer lid 20 by the tweezers holding portion 21.

Inside the enclosed bag 110, the outside of which is covered with the exterior body 151, a number of sanitary sheets 111 are stored as a sheet-type laminate.

In this sanitary sheet packaging body 150, the sanitary sheets 111 stored in the enclosed bag 110 within the outer body 151 can be removed one by one from the removal opening 152 of the outer body 151 by opening the outer lid 20 of the opening/closing lid 50 and grasping the sanitary sheets 111 with tweezers 40 removed from the tweezers holding portion 21. This allows the sanitary sheets 111 to be removed cleanly from the enclosed bag 110 without coming into contact with germs on the hands.

Although the main body of the exterior body 151 is formed from an inexpensive paper box, it may be a sanitary sheet container having a capacity for storing sanitary sheets 111 and a lid that is opened and closed when refilling the storage section, and the opening provided in the lid for taking out the sanitary sheets one by one from the container may be closed so as to be freely opened and closed by the openable lid 50. The enclosed bag 110 contained in the exterior body 151 contains a sheet-type laminate of the sanitary sheets 111, but even if the enclosed bags 110A, 111B contain a laminate of wet tissues 111A, 111B corresponding to the pop-up type, the wet tissues 111A, 111B can be grasped with the tweezers 40 removed from the tweezers holding section 21 and taken out one by one from the outlet 152 of the exterior body 151.

Here, in the sanitary sheet packaging body 100, 150, a tweezers holding part 21 for detachably holding the tweezers 40 separated by removing the bridge part 12 from the inner lid 10 is provided on the underside 20A of the outer lid 20, and the tweezers 40 separated by removing the bridge part 12 from the inner lid 10 is detachably held by the tweezers holding part 21 and is accommodated in the space of the opening 11 of the inner lid 10 when the outer lid 20 of the opening/closing lid 50 is closed, but even if the tweezers holding part 21 is not provided on the underside 20A of the outer lid 20, the tweezers 40 separated from the inner lid 10 can be accommodated in the space of the opening 11 of the inner lid 10 when the outer lid 20 of the opening/closing lid 50 is closed. Therefore, as in the opening/closing lid 50' according to another embodiment of the present invention described next, a tweezers holding part does not have to be provided on the underside 20A of the outer lid 20.

In addition, in the above-mentioned sanitary sheet packaging bodies 100, 150, the opening/closing lid 50 is formed by integrally molding the inner lid 10, outer lid 20 and tweezers 40 from flexible resin, and the inner lid 10 and the outer lid 20 are integrated via a thin hinge portion 30, but as in the opening/closing lid 50' according to another embodiment of the present invention described below, the inner lid 10' and the outer lid 20' may be molded separately from flexible resin and connected and integrated by the hinge portion 30'.

Next, an opening/closing cover 50' and a sanitary sheet package 100' according to another embodiment of the present invention.
The configuration of the above will be described with reference to the drawings.

Figure 10 is an oblique view of the sanitary sheet packaging body 100' showing the state in which the opening/closing lid 50' adhered to the removal opening 112 of the enclosed bag 110 is opened, and Figures 11A, 11B, 11C and 12A and 12B are figures showing the structure of the inner lid 10' of the opening/closing lid 50', where Figure 11A is a plan view of the inner lid 10', Figure 11B is a front view of the inner lid 10', Figure 11C is a bottom view of the inner lid 10', Figure 12A is a cross-sectional arrow view of the inner lid 10' taken along line A-A, and Figure 12B is a cross-sectional arrow view of the inner lid 10' taken along line B-B.

In addition, Figures 13A, 13B, 13C, and 14A and 14B are figures showing the structure of the outer lid 20' of the opening/closing lid 50', where Figure 13A is a plan view of the outer lid 20', Figure 13B is a front view of the outer lid 20', Figure 13C is a bottom view of the outer lid 20', Figure 14A is a cross-sectional arrow view of the outer lid 20' taken along line A-A, and Figure 14B is a cross-sectional arrow view of the outer lid 20' taken along line B-B.

In the opening/closing lid 50' and sanitary sheet packaging body 100' according to this other embodiment of the present invention, components that are the same as those in the opening/closing lid 50 and sanitary sheet packaging body 100 described above are given the same symbols or the same symbols with an "'" and detailed descriptions of them are omitted.

As shown in FIG. 9, this sanitary sheet package 100' has an opening/closing lid 50' adhered to the outlet 112 of an enclosed bag 110 that contains a sanitary sheet laminate in which a plurality of sanitary sheets 111 are laminated. By opening the outer lid 20' of the opening/closing lid 50', the sanitary sheets 111 can be grasped with tweezers 40 separated from the inner lid 10' and removed one by one from the outlet 112 of the enclosed bag 110.

This opening/closing lid 50' is formed by molding the inner lid 10' and the outer lid 20' separately from flexible resin and connecting them together with a hinge portion 30', and when closed, the rectangular opening/closing lid 50' has two hinge portions 30' on the rear edge side, and a finger hook portion 23' for opening the outer lid 20' is provided on the front edge side. The hinge portion 30' in this opening/closing lid 50' consists of an inner lid side hinge half 30A and an outer lid side hinge half 30B, and the finger hook portion 23' consists of an inner lid side hinge half 23A and an outer lid side hinge half 23B.

11A, 11B, and 11C, the inner lid 10' of the opening/closing lid 50' is a rectangular flat frame having an opening 11, in which tweezers 40 are disposed and which are molded from resin integrally with the inner lid 10 via a bridging portion 12. The tweezers 40 can be separated from the inner lid 10 by removing the bridging portion 12.

The bridging portion 12 consists of four bridging portions 12a, 12b, 12c, and 12d, with the bridging portions 12a and 12b extending from the tip portions 40a and 40b of the tweezers 40 and the bridging portions 12c and 12d extending from the base portion 40c. However, the number of bridging portions does not necessarily have to be four, and it is sufficient that the tweezers 40 remain integrated with the inner lid 10' until the tweezers 40 is separated from the inner lid 10, and at least any one of the four bridging portions 12a, 12b, 12c, and 12d is sufficient.

In addition, two inner rings 13A, 13B are provided on the upper surface 10A of the inner lid 10 so as to surround the opening 11: an inner ring 13A on the inner periphery side along the opening 11, and an inner ring 13B on the outer periphery side along the outer periphery of the inner lid 10.

An inner lid side finger hook half 23A having a cross-sectional shape shown in the cross-sectional arrow view of line A-A in Figure 12A is provided on the front edge side of the outer circumferential inner ring 13B, and an inner lid side hinge half 30A having a cross-sectional shape shown in the cross-sectional arrow view of line A-A in Figure 12B is provided on the rear edge side of the outer circumferential inner ring 13B.

In addition, the outer lid 20' of this opening/closing lid 50' is a flat plate molded from resin into a rectangular shape corresponding to the outer shape of the inner lid 10, as shown in Figures 13A, 13B, and 13C, and has two inner rings 22A, 22C that fit into two inner rings 13A, 13B provided on the inner lid 10.

An outer lid side finger hook half 23B having a cross-sectional shape shown in the cross-sectional arrow view of line A-A in Figure 14A is provided on the front edge side of the outer peripheral inner ring 22C, and an outer lid side hinge half 30B having a cross-sectional shape shown in the cross-sectional arrow view of line A-A in Figure 14B is provided on the rear edge side of the outer peripheral inner ring 22C.

The finger hook portion 23' in this opening/closing lid 50' consists of the inner lid side finger hook portion half 23A and the outer lid side finger hook portion half 23B, which are butted together when the outer lid 20' is closed, and the hinge portion 30' is formed by supporting the outer lid side hinge portion half 30B in such a way that it can pivot freely into the inner lid side hinge portion half 30A.

When the opening 11 of the inner lid 10' is blocked by the outer lid 20', the opening/closing lid 50' can be opened by pinching the outer lid side finger hook half 23B of the finger hook portion 23' located on the opposite side from the hinge portion 30'.

In this opening/closing lid 50', the hinge portion 30' in which the outer lid side hinge half 30B is pivotally fitted and supported on the inner lid side hinge half 30A, as shown in the longitudinal cross-sectional view of the open state in Figure 15, the rear edge side of the inner ring 22C on which the outer lid side hinge half 30B is provided abuts against the rear edge side of the inner ring 22C on which the inner lid side finger hook half 23A is provided, thereby determining the maximum angle at which the outer lid 20 can be opened, and the outer lid 20 can be maintained in an open position at the maximum angle, as in the sanitary sheet package 100' shown in the oblique view of Figure 10.

This sanitary sheet package 100' has an opening/closing lid 50' attached to the removal opening 112 of an enclosed bag 110 which contains a sanitary sheet laminate consisting of multiple laminated sanitary sheets 111 inside. The opening/closing lid 50' is formed by connecting an inner lid 10' and an outer lid 20' which are individually molded from flexible resin by a hinge portion 30' to form an integrated body. By opening the outer lid 20' of the opening/closing lid 50', the sanitary sheets 111 can be grasped with tweezers 40 separated from the inner lid 10' and removed one by one from the removal opening 112 of the enclosed bag 110, allowing the sanitary sheets 111 to be removed cleanly from the enclosed bag 110 without coming into contact with germs on the hands.

The enclosed bag 110 is not limited to an enclosed bag containing a sheet-type laminate of sanitary sheets 111, but may be an enclosed bag 110A, 111B containing a laminate of wet tissues 111A, 111B corresponding to a pop-up type, and the wet tissues 111A, 111B can be grasped with tweezers 40 separated from the inner lid 10' and taken out one by one from the outlets 112, 112A, 112B of the enclosed bags 110, 110A, 110B. It goes without saying that the open-close lid 50 in the sanitary sheet package 150 with the open-close lid 50 may be the open-close lid 50'.

In the opening and closing lid 50, 50' structured as described above, the inner lid 10, 10', outer lid 20, 20' and tweezers 40 are integrally molded from flexible resin, so there is no need to manufacture and set the tweezers as separate parts, and costs can be reduced by reducing the number of steps required for manufacturing and managing the product. Furthermore, by adhering the sanitary sheet removal opening of the sanitary sheet packaging body 100, 100', 150 which stores a laminate of sanitary sheets inside, the sanitary sheet removal opening can be blocked so as to be freely opened and closed, so there is no need to set the tweezers in the lid portion, and the sanitary sheet packaging body 100, 100', 150 which has been designed to reduce costs can be shipped.

In addition, with the opening and closing lids 50, 50', the sanitary sheets 111 can be grasped with tweezers 40 separated from the inner lids 10, 10' and removed one by one from the removal opening 112 of the enclosed bag 110, allowing the sanitary sheets 111 to be removed cleanly from the enclosed bag 110 without coming into contact with germs on the hands.

Furthermore, in the opening/closing lid 50, a tweezers holding portion 21 that removably holds the tweezers 40 separated by removing the bridging portion 12 from the inner lid 10 is provided on the underside 20A of the outer lid 20.Therefore, the tweezers 40 separated by removing the bridging portion 12 from the inner lid 10 can be removably held by the tweezers holding portion 21.Therefore, there is a problem that if used tweezers 40 are carelessly placed on the floor, etc., it becomes unhygienic, but by ensuring a storage place for used tweezers 40, such a problem is solved.

Here, in the enclosed bags 110A, 110B containing a stack of wet tissues 111A, 111B corresponding to the pop-up type, the removal openings 112A, 112B of some of the wet tissues 111A, 111B pop up, i.e., are pulled out, which poses a problem from a hygienic point of view. However, in the enclosed bag 110 containing a sheet-type stack of sanitary sheets 111, such problems are eliminated, and the removal opening 112 of the enclosed bag 110 to which the opening/closing lid 50 is attached can be an approximately elliptical shape with a width of 5 mm through which tweezers 40 can be inserted, or the entire opening area, in order to ensure the hygiene of the sanitary sheet 111, and it is preferable for it to be an elliptical shape with a width of about 5 mm to 20 mm. By making the removal opening 112 of the enclosed bag 110 small, the sanitary sheet 111 in the enclosed bag 110 is less likely to come into contact with outside air, and it is possible to prevent a user from accidentally touching the sanitary sheet 111 in the enclosed bag 110, thereby ensuring the hygiene of the sanitary sheet 111. Furthermore, the removal opening 112 of the enclosed bag 110 does not need to be provided in the center, and no matter where it is provided, the sanitary sheet 111 in the enclosed bag 110 can be removed by inserting the tweezers 40.
