  By the way, the lid member described in Patent Document 1 includes a base part bonded to the top surface of the package, and a cover part that can be opened and closed with respect to the base part. The outlet is opened and closed. However, with such a configuration, it is difficult to completely close the gap between the base portion and the lid portion, and there is a problem that a gap is easily formed between the two portions and sufficient airtightness cannot be obtained. For this reason, even if the outlet of the package is closed by the lid member, the chemical liquid impregnated in the wet sheet in the package may volatilize and gradually dry.

  Moreover, the cover member of Patent Document 1 is coated with an adhesive, and can be detachably attached to the package. However, during repeated use of the lid member, dust or dirt is likely to adhere to the lid portion for closing the outlet. As a result, there is a problem that dust and dirt are transferred from the lid portion of the lid member to the wet sheet in the package, and it is difficult to maintain the sanitary condition in the package.

  Accordingly, an object of the present invention is to provide a lid member that can improve the airtightness in the package. In addition, a further object of the present invention is to provide a lid member that can maintain the sanitary condition in the package.

  The inventor of the present invention, as a result of earnestly examining the means for solving the conventional problems, attached a non-breathable sheet member to the inner surface of the lid portion that can be opened and closed on the base portion of the lid member for the package. With this sheet member, the opening of the base part or the outlet of the package was sealed. In this way, by sealing the opening of the base part or the outlet of the package with the sheet member, even if there is a gap between the base part and the lid, the air tightness in the package is ensured. can do. In addition, it is possible to maintain the sanitary condition in the package by devising such that the sheet member is less likely to be contaminated with dirt and dust. Based on the above knowledge, the inventor came up with the idea that the problems of the prior art could be solved, and completed the present invention. Specifically, the present invention has the following configuration.

  The present invention relates to a lid member 20 that can be attached to an outlet 11 of a package 10 that stores a sheet-like material. The lid member 20 according to the present invention is suitable for attachment to a package 10 that accommodates a wet sheet, for example. In particular, the lid member 20 according to the present invention is preferably one that can be detachably attached to the package 10. The lid member 20 includes a base portion 21, an opening portion 22 provided in the base portion 21, and a lid portion 23 provided so as to be openable and closable with respect to the base portion 21 and opening and closing the opening portion 22. Furthermore, the lid member 20 includes a non-breathable sheet member 24 that is provided on the inner surface side of the lid portion 23 and covers the outlet 11 or the opening 22 when the lid portion 23 is closed. That is, the sheet member 24 provided in the lid part 23 may seal the outlet 11 of the package 10 or may seal the opening 22 of the base part 21.

  As described above, by providing a non-breathable sheet member 24 on the inner surface side of the lid portion 23 of the lid member 20, the sheet member 24 opens the opening 11 of the package 10 or the base portion 21. 22 can be sealed. Even when the take-out 11 or the opening 22 is directly closed by the non-breathable sheet member 24 as described above, even if there is a gap between the base portion 21 and the lid portion 23 of the lid member 20, the packaging The airtightness in the body 10 can be maintained. Thereby, it can suppress that the chemical | medical solution which impregnated the wet sheet in the package 10 volatilizes, and can prevent a wet sheet from drying early.

  In the present invention, the sheet member 24 is preferably stretchable and has a plurality of irregularities on at least the surface facing the package 10. The sheet member 24 may be formed of a known elastic material such as rubber or silicone. Further, the thickness of the sheet member 24 is preferably 1 mm or less, specifically 0.1 mm to 1 mm. By reducing the thickness of the sheet member 24 to 1 mm or less, the lid portion 23 is prevented from becoming difficult to close.

  By adopting the sheet member 24 having a plurality of irregularities formed on the surface as in the above configuration, the antifouling property of the sheet member 24 can be enhanced. That is, if the opening / closing operation of the lid portion 23 and the operation of taking out the wet sheet are repeated, the fiber of the sheet and the surrounding dust may adhere to the sheet member 24, resulting in an unsanitary state. In this regard, as described above, by forming fine irregularities on the surface of the sheet member 24, it is possible to prevent such dirt from adhering, and as a result, the hygienic condition inside the package 10 is effectively maintained. be able to. As for the uneven structure formed in the sheet member 24, it is preferable that the unevenness | corrugation is formed in the pitch of the range of 1 nm-500 micrometers or 1 nm-1 micrometer, for example.

  In the present invention, it is preferable that the sheet member 24 is coated with at least a preservative or an antifungal agent on the surface facing the package 10 or is kneaded with an antiseptic or antifungal agent. The sheet member 24 kneaded with the antiseptic or antifungal agent means a material in which the antiseptic or antifungal agent is mixed in the material forming the sheet member 24. As the preservative, a known one can be used as an anti-corrosion agent for rubber or silicone.

  As described above, by applying or kneading the preservative to the sheet member 24, the sanitary state of the lid member 20 to which the sheet member 24 is attached can be maintained. In addition, the wet sheet may generate mold odor depending on the usage environment. Therefore, by applying or kneading the mold preventive material to the sheet member 24, it is possible to suppress the occurrence of mold on the wet sheet.

  In the present invention, the lid portion 23 has a frame-shaped first protrusion 25 provided on the inner surface side so as to surround the outlet 11 or the opening 22 when the lid portion 23 is closed. It is preferable. In this case, the sheet member 24 is preferably stretched on the first protrusion 25.

  As in the above-described configuration, the frame-shaped first protrusion 25 is formed on the inner surface of the lid 23 and the sheet member 24 is stretched over the top of the cover 23. The outlet 11 or the opening 22 of the base portion 21 can be effectively sealed.

  In the present invention, the base portion 21 has a frame-like second protrusion portion 26 provided around the opening portion 22 and inserted into the frame-like first protrusion portion 25 when the lid portion 23 is closed. It is good as well.

  As described above, the base portion is formed in such a manner that the frame-like first protrusion 25 is provided on the lid 23, the sheet member 24 is stretched thereon, and is inserted into the first protrusion 25. By providing the second protrusion 26 on 21, the opening 22 of the base 21 can be more effectively sealed. In particular, since tension is applied to the sheet member 24 stretched on the first protrusion 25 by the second protrusion 26 of the base portion 21, the sheet member 24 comes into close contact with the second protrusion 26. It becomes like this. As a result, the opening 22 of the base portion 21 is almost completely sealed.

  In the present invention, the sheet member 24 may directly cover the outlet 11 of the packaging body 10 when the lid portion 23 is closed with the lid member 20 attached to the packaging body 10. That is, structurally, a frame-like first protrusion 25 provided on the lid 23 is inserted into the opening 22 of the base 21 and the sheet stretched on the first protrusion 25. The member 24 is in direct contact with the package 10 and closes the outlet 11.

  As described above, the packaging body 10 can be effectively sealed by directly closing the outlet 11 of the packaging body 10 using the sheet member 24 provided on the lid member 20.

  According to the lid member according to the present invention, the airtightness in the package can be improved. In addition, according to the lid member of the present invention, it is possible to maintain the sanitary condition in the package.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments described below, and includes those appropriately modified by those skilled in the art from the following embodiments.

[1. First Embodiment]
First, a first embodiment of a lid member according to the present invention will be described. 1 to 3 show a lid member 20 according to a first embodiment of the present invention.

  FIG. 1 is a perspective view showing the packaging body 10 according to the first embodiment, and shows a state in which a lid member 20 attached to the packaging body 10 is opened. The package 10 stores a plurality of sheets in a folded state. An example of the sheet-like material is a wet sheet. However, the package 10 is not limited to wet sheets, and sanitary paper such as tissue paper and toilet paper can also be accommodated. Here, specifically, a case where a wet sheet is accommodated in the package 10 will be described as an example.

  The package 10 is substantially square or flat so that a plurality of wet sheets can be accommodated. The package 10 has a top surface 12, a bottom surface 13 that faces the top surface 12, and a side surface 14 that connects the top surface 12 and the bottom surface 13, and the top surface 12, the bottom surface 13, and the side surface 14 form a wet sheet. The storage space is formed. An outlet 11 for taking out the wet sheet is formed on the top surface 12 of the package 10. The size and shape of the outlet 11 are not particularly limited as long as the wet tissue can be taken out. For example, the outlet 11 can be molded by cutting a hole having a shape designed in advance at an appropriate position on the film constituting the package 10.

  The package 10 containing the wet sheet is liquid-impermeable with airtightness in order to prevent the impregnating liquid, such as a drug or a cosmetic material, that has penetrated or applied to the wet sheet from leaking or volatilizing. It is formed with film. Such films include plastic films such as polyethylene, polypropylene, polyester, polyamide, vinyl chloride, vinylidene chloride, cellophane, or acetate, a laminated film composed of a combination of two or more of these films, or an aluminum film on this laminated film. A composite film formed by further laminating a foil is mentioned. Moreover, this package 10 may be a laminate of a metal-deposited PET film and a PE film.

  On the other hand, as shown in FIG. 1, the lid member 20 is attached to the top surface 12 in order to close the outlet 11 of the package 10. The lid member 20 is provided on the top surface of the packaging body 10 for the purpose of improving the shape retention of the packaging body 10 made of a soft film and facilitating removal of the wet sheet through the outlet 11 of the packaging body 10. 12 is detachably attached.

  The lid member 20 has an annular base portion 21. An opening 22 is provided in the central portion of the base portion 21, and the wet sheet stored in the package 10 can be taken out from the outlet 11 through the opening 22. Further, a lid portion 23 is connected to the base portion 21 through a hinge portion 27 so as to be freely opened and closed. The lid part 23 opens and closes the opening part 22 formed at the center of the base part 21 when the hinge part 27 is refracted. The lid part 23 has an area larger than at least a region including the opening part 22, and the opening part 22 is closed by closing the lid part 23. Thereby, the airtight state of the storage space of the package 10 can be maintained by attaching the lid member 20 to the package 10 and closing the lid 23. FIG. 2 shows a state where the lid portion 23 of the lid member 20 is closed.

  The base portion 21 of the lid member 20 is preferably formed of a member that is harder than the film constituting the package 10. For example, as a member that forms the base portion 21 of the lid member 20, a known member such as a thermoplastic resin such as polypropylene, polyethylene, polyvinyl chloride, polystyrene, or acrylic resin, a metal such as aluminum, or wood is appropriately selected. Can be used. In particular, the member constituting the base portion 21 of the lid member 20 is preferably a thermoplastic resin. Further, as the members constituting the lid part 23 and the hinge part 27, the same members as those constituting the base part 21 can be used. In the embodiment shown in FIGS. 1 and 2, the shape of the lid portion 23 is substantially circular. However, the shape of the lid portion 23 is not limited to a substantially circular shape, and may be any shape as long as the opening portion 22 formed in the base portion 21 can be appropriately closed.

  The opening 22 provided in the center of the base portion 21 of the lid member 20 is provided to take out the wet sheet through the outlet 11 of the package 10 when the lid portion 23 is opened. The shape of the opening 22 of the lid member 20 is not limited to the shape shown in FIGS. 1 to 3, and any shape such as a substantially circular shape, an elliptical shape, a triangular shape, or a quadrangular shape can be employed.

  Furthermore, as shown in FIG. 1, in the present invention, a frame-shaped first protrusion 25 is formed on the inner surface of the lid portion 23 (the surface facing the base portion 21 when closed). In the example of FIG. 1, the frame-shaped first protrusion 25 is a substantially rectangular frame, but is not particularly limited to this shape, and may be any shape such as a circular shape, an elliptical shape, or a triangular shape. The shape can be adopted. The height of the first protrusion 25 can be adjusted as appropriate, but is preferably about 2 mm to 10 mm, for example.

  Further, a non-breathable sheet member 24 is stretched on the frame-shaped first protrusion 25 provided on the inner surface of the lid 23. That is, the sheet member 24 is stretched in a state where a certain tension is applied to the top of the frame-shaped first protrusion 25. The sheet member 24 is a thin film formed of a non-breathable member having elasticity such as rubber or silicone. Further, the thickness of the sheet member 24 is preferably 1 mm or less, specifically 0.1 mm to 1 mm. In the example shown in FIG. 1, the sheet member 24 is formed of a transparent material, but may be formed of a translucent or opaque material.

  On the other hand, a recess 28 is formed around the opening 22 of the base 21. The recess 28 has a depth that is at least greater than the height of the first protrusion 25 of the lid 23. For example, the recess 28 preferably has a depth of about 1.1 to 2 times the height of the first protrusion 25. For this reason, even if it is a case where the above-mentioned 1st projection part 25 is formed in the cover part 23, as shown in FIG. 2, the cover part 23 can be closed without a problem.

  In addition, a frame-like second protrusion 26 is formed in the recess 28 of the base portion 21 along the edge of the opening 22 so as to surround the periphery of the opening 22. The height of the frame-shaped second protrusion 26 is smaller than the depth of the recess 28 formed in the base portion 21. For this reason, the second protrusion 26 does not protrude from the recess 28. Thereby, as shown in FIG. 2, the cover part 23 can be closed. The second protrusion 26 provided on the base portion 21 is similar to the first protrusion 25 provided on the lid 23 and is slightly smaller than the first protrusion 25. Has been. For this reason, when the lid portion 23 is closed, the second protrusion 26 is inserted into the first protrusion 25. That is, the second protrusion 26 is fitted inside the first protrusion 25.

  3 shows a cross-sectional view taken along line III-III shown in FIG. 2, that is, a cross-sectional view of the lid portion 23 in a closed state. As shown in FIG. 3, in the state where the lid portion 23 is closed, the frame-shaped second protrusion provided on the base portion 21 in the frame-shaped first protrusion 25 provided on the lid portion 23. The projection 26 is inserted. Here, as described above, the stretchable sheet member 24 is stretched on the first protrusion 25 of the lid 23. For this reason, in a state in which the lid portion 23 is closed, the second protrusion 26 pushes up the sheet member 24 stretched on the first protrusion 25 and elastically deforms it. In this way, the second protrusion 26 applies tension to the sheet member 24. Then, the sheet member 24 comes into close contact with the top of the second protrusion 26. As a result, the upper portion of the opening 22 formed in the frame of the second protrusion 26 is sealed by the sheet member 24.

  Thus, by providing the non-breathable sheet member 24 on the inner surface side of the lid portion 23 of the lid member 20, the opening portion 22 of the base portion 21 can be sealed by the sheet member 24. And even if it is a case where the clearance gap has arisen between the base | substrate part 21 and the cover part 23 of the cover member 20 by directly obstruct | occluding the opening part 22 with the non-breathable sheet | seat member 24, the inside of the package 10 is provided. Airtightness can be maintained. Thereby, it can suppress that the chemical | medical solution which impregnated the wet sheet in the package 10 volatilizes, and can prevent a wet sheet from drying early.

  In addition, as the sheet member 24, it is preferable that a plurality of irregularities be formed at least on the surface facing the package 10. Of course, irregularities may also be formed on the surface that does not face the package 10. Thus, the antifouling property of the sheet member 24 can be enhanced by adopting the sheet member 24 having a plurality of irregularities formed on the surface. That is, if the opening / closing operation of the lid portion 23 and the operation of taking out the wet sheet are repeated, the fiber of the sheet and the surrounding dust may adhere to the sheet member 24, resulting in an unsanitary state. In this regard, as described above, by forming fine irregularities on the surface of the sheet member 24, it is possible to prevent such dirt from adhering, and as a result, the hygienic condition inside the package 10 is effectively maintained. be able to. As for the uneven structure formed in the sheet member 24, it is preferable that the unevenness | corrugation is formed in the pitch of the range of 1 nm-500 micrometers or 1 nm-1 micrometer, for example.

  Further, the sheet member 24 may be one in which a preservative or a fungicide is applied to at least the surface facing the package 10 or a preservative or a fungicide is kneaded. The preservative is used to prevent the sheet member 24 itself from being spoiled. The fungicide prevents mold from forming on the wet sheet that is easy to touch the sheet member 24. Known antiseptics and fungicides can be used as appropriate.

  Further, as shown in FIG. 3, an adhesive layer 29 is formed on the bottom surface of the base portion 21. The pressure-sensitive adhesive layer 29 may be any material as long as the lid member 20 can be detachably attached to the package 10, and a known pressure-sensitive adhesive or double-sided tape can be used. An example of the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 29 is a hot-melt pressure-sensitive adhesive or an acrylic pressure-sensitive adhesive. In particular, the pressure-sensitive adhesive is preferably used with a hot melt adhesive. In this way, by providing the adhesive layer 29 on the base portion 21 of the lid member 20 so that the lid member 20 can be repeatedly attached to and detached from the packaging body 10, the lid member 20 can be used and is economical.

  In addition, if the wet sheet accommodated in the inside of the package 10 is a well-known thing, it can select suitably and can be used. The wet sheets are usually formed in a square shape and are included in the package 10 in a state of being stacked in layers. Wet sheets may be folded one by one into an appropriate size and stacked, or so-called pop-ups where the front and back parts of the folded wet sheet are overlapped on adjacent wet sheets and caught on each other It may be laminated in a form. If the wet sheets are stacked in a pop-up format, the upper end of the next wet sheet is automatically lifted after the first wet sheet is taken out, so there is an advantage that it becomes easier to take out the wet sheets continuously. Further, it is not always necessary to stack wet sheets and store them in the package 10. For example, a series of roll-shaped wet sheets provided with perforations for cutting at equal intervals are stored in the package 10. It is good to do. As the wet sheet, for example, a sheet material in which an impregnating liquid is permeated or applied can be used. Examples of the sheet material are paper, woven fabric, non-woven fabric, cotton, gauze, or foamed sheet made of synthetic fiber or natural fiber. Examples of the impregnating liquid are drugs or cosmetic materials. Moreover, as a chemical | medical agent, alcohol for disinfection can be used, for example.
