Have been. In this outlet, many products are fitted with a packing provided with an extraction hole in the center so that the drawn-out roll-shaped wet tissue can be more reliably cut from a perforation to a predetermined length. Can be

  For example, Patent Literature 1 discloses a wet tissue outlet member (packing) detachably provided at an outlet, a small hole formed at a center side of the outlet member, and a small hole from the outer periphery of the outlet member. An outlet member in which a connected slit-shaped dividing portion is formed is disclosed. When a new wet tissue is loaded into the container provided with the take-out member, the first end of the wet tissue can be easily passed through the small hole through the dividing portion of the take-out member, and the wet tissue is small. By fitting the outlet member passed through the hole into the outlet, the slit-shaped dividing portion closes, so that the wet tissue pulled out from the small hole can be taken out one by one while being cut at the perforation. .

  However, in the case of the outlet member disclosed in Patent Literature 1, every time a new wet tissue is refilled in the storage container, the outlet member must be attached and detached. If the takeout member is lost, the storage container may not be able to be used. In addition, as shown in FIG. 7, the inside of the container of the packing 70 is recessed as shown in FIG. The finger 73 is difficult to reach the vicinity of an extraction hole 72 provided at a portion corresponding to the bottom of the concave portion 71, and it is difficult to insert the wet tissue 74 because the tip of the wet tissue 74 is widened. In order to push the rod into the extraction hole 72, for example, it is necessary to separately prepare a bar-shaped member having a thin tip.

  Patent Document 2 discloses a storage container having an extraction portion (packing) including an elastically deformable surface portion and an extraction hole provided in the surface portion and through which a wet tissue is inserted. When refilling, the opening of the extraction hole can be widened by pushing the face of the extraction part into the inside of the container body and deforming it, and it becomes easier to insert wet tissue into the extraction hole where the opening has widened, and refill the wet tissue It is stated that a storage container that can easily perform the above is obtained.

  However, as shown in FIG. 8, when the face 81 of the take-out part 80 is pushed into the inside of the container with a finger 84 or the like, the take-out part of Patent Document 2 cannot maintain the state, and thus the deformation is maintained. In order to insert the wet tissue 83 into the extraction hole 82, the extraction hole 82 may be covered with the finger 84 or may be difficult to see. Therefore, there is a problem that it becomes difficult to insert the tip of the wet tissue 83 even if the take-out hole 82 is slightly widened.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments described below. In the following, the same reference numerals are given to the same members and the like, and the description may be omitted.

  FIG. 1 is a cross-sectional view of one embodiment of the packing of the wet tissue storage container of the present invention. The packing 10 is used by being fitted in a form to be fitted into an outlet of a wet tissue container. The packing 10 is made of an elastic material such as rubber, and has a surface portion 12 that is curved such that a central portion is a vertex inside a ring-shaped edge portion 11, and a take-out hole 13 for a wet tissue is provided in the central portion of the surface portion 12. It is provided penetrating the surface portion 12. Then, a ridge portion 14 that protrudes from the surface portion 12 around the extraction hole 13 is provided.

  As shown in FIG. 1A, the surface portion 12 can hold a shape that is convexly curved outward (here, upward in the figure) of the container without applying an external force for maintaining the shape, Further, by pushing the surface portion 12 from above in the figure, the curved surface portion 12 can be inverted downward, and as shown in FIG. The shape can be maintained without applying an external force for maintaining the shape. In particular, at the time of molding, as shown in FIG. 1 (a), the container is generally formed in a shape that is convexly curved outward.

  At this time, the peripheral end portion 15 where the surface portion 12 and the edge portion 11 connect acts like a hinge, but at the same time, due to its elasticity, when the surface portion 12 is turned downward, the force for returning the surface portion 12 upward is given. Works. In order to actually return upward, it is necessary to deform the surface portion 12, especially the portion of the extraction hole 13, but since the ridge portion 14 stands up around the extraction hole 13, the rigidity of the portion of the extraction hole 13 is increased. And deformation is less likely to occur. As a result, the surface portion 12 does not return to the upwardly convex shape only by the force due to the elasticity of the peripheral end portion 15, and the surface portion 12 has a downwardly convex shape and applies an external force for maintaining the shape. Hold without.

  FIG. 2 is a plan view of one embodiment of the packing of the wet tissue storage container of the present invention. A surface portion 12 is provided inside the ring-shaped edge portion 11, and a take-out hole 13 for wet tissue is provided in the center of the surface portion 12. A ridge 14 is provided around the extraction hole 13. In the present embodiment, the outer shape of the packing 10 is circular, but the packing of the present invention is not limited to this, and may be, for example, an ellipse, a polygon, a rounded polygon, or the like.

  An embodiment in which a wet tissue is attached to the packing of the present invention will be described. FIG. 3 is an explanatory view of a mode of inserting the tip of a wet tissue into the packing of the present invention. When attaching the wet tissue 16 to the packing 10, first, the surface portion 12 is formed to have a shape that protrudes inside the container, and the extraction hole 13 is made to be the tip of the portion that protrudes inside the container. Then, the tip of the wet tissue 16 is thinned by twisting or the like, and is pinched with a finger 31 and inserted into the extraction hole 13. At this time, since the take-out hole 13 is the tip of the portion that is convex inside the container, the vicinity of the tip of the wet tissue 16 can be pinched by the finger 31 to easily approach the take-out hole 13 and the tip of the wet tissue 16 can be easily obtained. Easy to insert.

When the tip of the wet tissue 16 is inserted into the extraction hole 13, as shown in FIG. 4, the wet tissue 16 can be sequentially pulled out as needed with the tip of the wet tissue 16 protruding outside the container. In the process of pulling out the wet tissue 16, the surface portion 12 is pulled outward from the container due to frictional resistance between the wet tissue 16 and the surface portion 12 and the ridge portion 14 at the extraction hole 13, and the surface portion 12 has a convex shape outside the container. That is, when the wet tissue 16 is refilled, when the tip portion is inserted into the extraction hole 13, the surface portion 12 of the packing 10 is formed into a convex shape inside the container, and when the wet tissue 16 is pulled out and used, The surface portion 12 remains in a shape convex to the outside of the container.

  FIG. 5 is a view showing an example of the shape of the extraction hole. In addition to the circular shape shown in FIG. 2, the shape of the extraction hole may be a circular shape having cuts directed outward in the diametrical direction. Various shapes such as a provided shape, (b) a shape having a cross-shaped notch 52, and (c) a shape having a star-shaped notch 53 can be used. By providing the cuts, the take-out holes can be easily spread in accordance with the shape of the cuts, and the resistance when pulling out the wet tissue can be adjusted. The shape of the cut can be appropriately selected according to the thickness and material of the wet tissue to be inserted.

  FIG. 6 is a schematic cross-sectional view of a mode in which the packing of the present invention is fitted to the lid of a wet tissue storage container. The cover body 60 is provided with a thread 61 for screwing to the storage container main body on the inner surface, and the packing 10 is fitted to the outlet 63 on the upper side. The packing 10 is supported by the undercut portion 68 so as not to fall off. Since the packing 10 is made of an elastic material, it can be elastically deformed when fitted, and can easily go over the undercut portion 68 and be fitted to the lid 60.

  The take-out opening 63 is provided with an openable / closable lid piece 62 that fits with the fitting ridge 64 of the lid 60 and seals the take-out opening 63. The lid piece 62 seals the outlet 63 to prevent evaporation of volatile components such as moisture and alcohol from the wet tissue through the outlet of the packing 10.

  By lifting one end 65 of the lid piece 62, the lid piece 62 can be pivotally opened about the hinge 66, the outlet 63 is opened, and the wet tissue can be pulled out through the packing 10. Further, a concave portion 67 is provided in the lid body 60 to facilitate lifting the one end 65.

  The packing of the present invention is made of an elastic material. The material is preferably a rubber having a Shore hardness of 45 A or more. In particular, when durability and content resistance (for example, alcohol resistance, etc.) are required, silicone rubber is used. Is desirable. Also, an appropriate thickness is required.

  As described above, according to the packing of the present invention, when refilling a wet tissue, the tip of the wet tissue can be easily inserted into the extraction hole, and the removal of the first wet tissue is also easy. In addition, it is possible to provide a packing fitted to the outlet of the storage container.
