Description

  The present invention relates to a wet sheet storage container for storing a wet sheet impregnated with a liquid such as a wet tissue.

In order to maintain a wet state when not in use or not in use, the wet sheet is folded by a predetermined number of times in an airtight container or in a container that is contained in a refill packaging bag. It is housed in a state where In this type of wet sheet, the upper and lower wet sheets are stacked while having overlapping portions. When the uppermost wet sheet is taken out of the container, the outlet of the container is easily removed. A so-called pop-up type superposition structure in which a part thereof protrudes is employed.
A storage container for storing such a wet sheet generally includes a container body having an outlet on the top surface portion, and a lid body that is rotatably coupled to the top surface portion of the container body by a hinge or the like and covers the outlet port. And a structure that prevents the volatilization of the chemical liquid impregnated in the wet sheet accommodated therein is prevented by sealing between the periphery of the outlet and the lid by a sealing means.
As the sealing means, conventionally, an elastic material that is in close contact with the outlet formed on the top surface portion is disposed on the inner surface of the lid body (see Patent Document 1), or two provided on the inner surface of the lid body. An annular elastic packing is interposed between the heavy rings (inner ring and small ring), a seal ring is formed on the inner lid that forms part of the container top plate, and the tip of the seal ring closes the lid. There is known one that can fit between the double rings and abuts against the elastic packing so as to exert a sealing function (see Patent Document 2).

JP2000-142842 JP-A-11-49206

However, in these conventional sealing means, the top of the seal ring is easily separated from the elastic packing due to distortion and twist of the lid due to repeated opening and closing, and distortion and twist of the top surface part due to repeated removal of the wet sheet. Therefore, the sealing function may be insufficient, and the chemical liquid impregnated in the wet sheet may volatilize.
Further, in the conventional example, since the outlet is widely formed, the chemical solution is volatilized by simply opening and closing the lid, and the quality of the wet sheet may be deteriorated in a short period of time.
Therefore, a main problem of the present invention is to provide a wet sheet container that exhibits a reliable sealing function and holds the wet sheet in a wet state for a long period of time.

The present invention that has solved the above-described problems and the effects thereof are as follows.
<Invention of Claim 1>
A wet sheet storage container comprising a container main body having an opening formed on the upper surface, and a lid for closing the opening so as to be opened and closed,
A sheet-like airtight member is arranged so as to cover the opening,
The airtight member is formed with a wet sheet outlet, and a convex ridge portion arranged so as to surround the periphery of the outlet,
An annular standing wall surrounding the outlet of the airtight member is formed on the inner surface of the lid,
A wet sheet container, wherein the end of the standing wall of the lid when closed is in contact with the inner ridge line or inner inclined surface and the outer ridge line or outer inclined surface of the ridge portion.

(Function and effect)
Since the take-out port and the ridge portion are integrally formed, the structure is simple and the manufacture becomes easy. In addition, airtightness can be reliably ensured with a simple structure in which the standing wall abuts against the airtight member.

<Invention of Claim 2>
A standing wall of the lid is formed by an inner annular standing wall and an outer annular standing wall, and a tip portion of the inner annular standing wall is in contact with an inner ridge line or an inner inclined surface of the convex bank, and the outer annular standing wall The wet sheet container according to claim 1, wherein the tip portion is in contact with an outer ridge line or an outer inclined surface of the convex ridge portion.

(Function and effect)
In this invention, it is comprised so that an inner side annular standing wall and an outer side annular standing wall may each contact | connect a convex bank part. That is, according to the present invention, when the lid is closed, the outlet is sealed so as to be surrounded by at least two walls and is double-sealed. Therefore, conventionally, compared with the wet sheet container, the chemical liquid or the like is prevented from evaporating from the wet sheet stored in the container main body, thereby preventing the quality of the wet sheet from being deteriorated.

<Invention of Claim 3>
A groove for separating the inner edge piece and the outer edge piece is formed at the tip of the standing wall of the lid body, and the tip of the inner edge piece is in contact with the inner ridge line or the inner inclined surface of the convex ridge, and the outer edge piece The wet sheet storage container according to claim 1, wherein the tip end portion of the contact portion is in contact with the outer ridge line or the outer inclined surface of the convex bank portion.

(Function and effect)
In this invention, it is comprised so that an inner edge and an outer edge piece may each contact | connect a convex bank part. That is, according to the present invention, when the lid is closed, the outlet is sealed so as to be surrounded by at least two edge pieces and double sealed. Therefore, conventionally, compared with the wet sheet container, the chemical liquid or the like is prevented from evaporating from the wet sheet stored in the container main body, thereby preventing the quality of the wet sheet from being deteriorated.

<Invention of Claim 4>
The wet sheet storage container according to any one of claims 1 to 3, wherein a concave portion is formed on an upper surface of the container main body, and a sheet-like airtight member is fitted into the concave portion.

(Function and effect)
When an airtight member is attached to the inner surface of the lid body, it may be difficult to ensure airtightness (sealing performance) due to deformation of the lid itself due to repeated opening and closing of the lid body. By providing it on the upper surface, the quality of the wet sheet can be maintained for a longer period of time and more stably than when an airtight member is attached to the inner surface of the lid. Moreover, the arrangement of the airtight member is facilitated and the manufacture is facilitated.

<Invention of Claim 5>
The wet sheet container according to any one of claims 1 to 4, wherein the airtight member is made of a soft material or an elastic body.

(Function and effect)
By configuring the airtight member with a soft material or an elastic body, the airtight member can be deformed and pressed against the standing wall, and it becomes easier to ensure airtightness (sealing performance).

<Invention of Claim 6>
The wet sheet storage container according to any one of claims 1 to 5, wherein the outlet is a slit or a penetrating portion formed in an airtight member and opens and closes by a stretchability of the sheet.

(Function and effect)
Since the take-out port is a slit formed in the airtight member, when the airtight member is made of an elastic body or the like, the take-out edge of the wet sheet is slightly lifted upward by friction with the wet sheet. Along with the action of extending the vicinity of the exit edge, the take-out opening becomes slightly widened and the wet sheet can be easily taken out. After a single wet sheet is taken out, the stretched outlet edge immediately shrinks to minimize the opening that serves as a chemical volatilization path, so that the chemical of the wet sheet in the container at the time of removal is evaporated. Can be minimized.

  As described above, the basic structure of the present invention is that the airtight part represented by the convex bank and the outlet represented by the slit are formed in the same airtight member. And according to this invention, the reliable sealing function is exhibited and the wet sheet storage container which hold | maintains a wet sheet in a wet state over a long term is provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<First Reference Embodiment>
FIG. 1 is a front view of a wet sheet storage container X1 according to the present embodiment, FIG. 2 is a sectional view taken along II-II of the wet sheet storage container X1, and FIG. 3 is a wet sheet storage container with the lid 3 opened. 4 is a front view of X1, and FIG.

  As shown in FIGS. 1 to 4, the wet sheet storage container X <b> 1 according to the present embodiment includes a container body 2 having a bottom opening, a bottom lid 4 detachably attached to the bottom of the container body 2, and a container body. 2, and a lid 3 capable of opening and closing a take-out port 15 formed at the upper part of 2. Storage of the wet sheet W in the container body 2 is performed from the bottom 2B of the container body 2 by removing the bottom lid 4 from the container body 2.

  On the upper surface of the container body 2, there is formed a stepped portion 2 a having a substantially rectangular shape slightly larger than the lid body 3 and provided with a step that is one step lower than the upper surface of the container body 2 by the thickness of the lid body 3. Thus, when the lid 3 closes the opening 5, the uppermost surface portion of the container body 2 and the upper surface of the lid 3 are substantially flush with each other.

  In addition, a substantially elliptical recess 6 that is one step lower than the step 2a is formed on the upper surface of the container body 2 and substantially at the center of the step 2a. An opening 2H is formed. A space is formed between the inner surface side of the lid 3 and a later-described outlet 5 in a state in which the lid 3 is closed by the formation of the recess 6, and a wet sheet W protruding from the outlet 5 is formed in this space. The part fits.

  A sheet-like airtight member 5 having the same shape as that of the recess 6 and having the same size or slightly larger size is fitted in the recess 6. The airtight member 5 is made of a soft material such as silicon resin, a vulcanized rubber, a thermoplastic elastomer, an elastic fiber, an elastic foam, a synthetic rubber, or an elastic body such as polyethylene foam.

  The sheet-like airtight member 5 is supported by the peripheral edge 6b of the opening 2H (also the peripheral bottom of the recess) and covers the opening 2H of the container body 2. The airtight member 5 is formed with a cross slit-shaped outlet 15 above the opening 2H, so that the wet sheet W is formed in the container body 2 and passes through the opening 2H and the outlet 15. It is taken out. At the time of taking out, that is, when pulling out a part of the wet sheet W exposed from the take-out port 15, the edge of the take-out port 15 is slightly lifted upward by friction with the wet sheet. With the action of stretching the slit 15, the slit 15 widens and the wet sheet is taken out. Immediately after the single wet sheet is taken out, the slit edge contracts to minimize the slit opening that becomes the chemical vaporization path. In addition, the slit opening contracts immediately after one wet sheet is taken out, so that a part of the subsequent wet sheet is securely held, so that each wet sheet is reliably taken out. It makes possible a pop-up form suitable as

  Here, the sheet-like airtight member 5 is fixed in the concave portion 6 by, for example, providing a locking protrusion 14 on the peripheral bottom 6b of the recess and forming the locking protrusion 14 on the airtight member 5 as appropriate. You may make it fit in the fixing hole 16, and there are several locking protrusions (not shown) so as to protrude in the middle of the concave peripheral side wall 6s (for example, two in the short axis and long axis directions of the ellipse). 4 parts each) and an airtight member is sandwiched between the locking protrusion and the concave bottom, or a sheet-like airtight member is adhered to the peripheral bottom 6b of the concave with an adhesive. If so, it is easy.

  On the other hand, a convex bank portion 10 is formed in the airtight member 5 so as to surround the outlet 15. Up to the lower position of the convex ridge portion 10, the peripheral bottom portion 6b of the concave portion 6 of the container main body 2 extends, and the rigidity against pressing from the upper side is ensured to some extent.

  On the other hand, on the upper surface of the container main body 2, a lid body 3 is provided that can be opened and closed with one side of the container main body 2 as a rotation fulcrum (hinge part) 30. The lid body 3 is not used. Or when not in use, it is configured to close at least the area where the outlet 15 is formed, preferably the opening 2H. In addition, an elastic body (not shown) that allows the lid to be fully opened by an elastic restoring force is disposed in the vicinity of the hinge 30 and is engaged with each other when the lid provided on the container body and the lid is closed. It is possible to easily open the lid by releasing the locking mechanisms 21A and 21B that stop and keep the lid in the closed position.

  Here, in this embodiment, it stands characteristically in the vicinity of the center of the inner surface of the lid body 3 so as to protrude downward (inner surface side) from the top surface of the lid body, and the tip edge closes the lid body 3. An upright wall 11 formed in an annular shape is formed in contact with the hermetic member over the entire circumference in a state where the airtight member is in contact. Further, in this embodiment, the standing wall 11 is formed so as to be in contact with the vicinity of the inner base end portion of the convex ridge portion 10 formed in the airtight member 5 in a state where the lid 3 is closed. It contacts the airtight member 5 so as to surround it. That is, the abutting portion between the leading edge of the standing wall 11 and the airtight member 5 is an airtight portion according to the present invention. Here, as described above, since the concave peripheral bottom portion 6b of the container body 2 extends to the lower position of the convex ridge portion 10, the sheet-like airtight member 5 is excessively lowered by the contact of the tip of the standing wall 11. The surface of the airtight member 5 is pressed against the peripheral edge of the upright wall 11 appropriately according to the elastic force of the airtight member 5 itself.

  In this way, the standing wall 11 of the lid 3 and the sheet-like airtight member 5 abut with an appropriate pressure while the lid 3 is closed, and the wet sheet W stored in the container body 2 The chemical solution is prevented from evaporating to the outside through the outlet 15, and the quality of the wet sheet W is prevented from deteriorating.
