Description

  The present invention relates to a storage container for storing thin paper in which a large number of sheets are stacked, which is mainly used at home, such as wet tissue.

2. Description of the Related Art Conventionally, a storage container for storing laminated thin paper for wiping a human body or the like, or for wiping a floor or a toilet of a house is known.
This type of household laminated thin paper storage container is, for example, a storage space for storing laminated thin paper that is directly accumulated inside or individually wrapped, a container main body provided with an outlet for the laminated thin paper at the top, and There are some which are provided with an opening / closing lid which is provided at the upper part of the container main body so as to be rotatable and opens and closes the take-out port, and has been proposed. In either case, the opening / closing lid is rotated upward to open the take-out port, and the laminated thin paper is pulled out from the take-out port for use. After use, the opening / closing lid is pivoted downward to close the take-out port to prevent dust and dirt from adhering to the laminated thin paper. (For example, refer patent documents 1-8).

By the way, when many things open this kind of conventional storage container, this opening-and-closing lid stood up and is maintaining the open posture (refer to patent documents 1-6).
On the other hand, the situation when pulling out this kind of laminated thin paper from the container, especially when used as a wipe for infants such as babies, holding an infant in one hand or holding an infant's ankle, etc. It is a well-known fact that it is often used when one hand is often closed, such as the situation described above.

  Therefore, even if you try to pull out the laminated thin paper from the container with the other open hand under the condition that this one hand is blocked, the opening / closing lid interferes with the drawer, especially from the back side of the container. It was normal that I couldn't pull out well.

  On the other hand, in the course of various studies, there is also a case where the opening / closing lid is inverted 180 degrees from its closed position to greatly release the outlet (see Patent Documents 7 to 8).

  However, in this type, the lock structure for keeping the open / close lid in its closed position is generally a structure in which an engagement piece integrally projected from the open / close lid is engaged with a push piece provided continuously with the container body. (Refer to Patent Documents 6 to 7), or a notch provided in the opening / closing lid is locked to the engaging recess of the container body. For this reason, the engagement force weakens early, the open / close lid remains open, or the engagement between the engagement piece and the push piece is defective, making it difficult to open and the opening work taking time. Is seen. In either case, the opening / closing lid when in the open position protrudes greatly to the side of the container body and is caught on the limbs, which causes a problem in handling.

  Accordingly, an object of the present invention is to make it possible to easily and quickly pull out the laminated thin paper from either side of the container body even if one hand is closed.

In order to solve the above technical problem, a storage container having a slide-type opening / closing lid according to claim 1 of the present invention includes a storage space for storing laminated thin paper and an outlet for the laminated thin paper. A container main body and a pair of symmetrical open / close lids for closing and releasing the take-out port, and the open / close lid is mounted so as to be slidable substantially along the outer wall of the container main body A locking mechanism is provided between the opposing edges of the two opening / closing lids to maintain the closing posture of the take-out port by the two opening / closing lids, and the locking mechanism presses the upper surface of one of the two opening / closing lids. Thus, a structure that is configured so as to be unlockable and that is provided with a stopper that keeps the closed position of both opening and closing lids and prevents the other opening and closing lids from moving to the other opening and closing lid side is adopted.

  According to the above configuration, the lock can be released by pressing the edge of the opening / closing lid, and the removal opening can be opened by moving the opening / closing lid in parallel with the virtual plane where the removal opening exists. The opening / closing lid can be easily opened and closed with a single touch while being able to visually recognize the outlet from any side.

  Therefore, the storage container having the slide type opening / closing lid according to the first aspect of the present invention is different from the conventional product in which the opening / closing lid stands up and keeps the open posture and the conventional product in which the operation of the lock mechanism is unstable. Regardless of the orientation, the opening / closing lid can be easily opened and closed from either side, and at the same time, it can be accurately and quickly pulled out from the laminated thin paper take-out port without being obstructed by the opening / closing lid.

  In order to solve the above technical problem, as described in claim 2 of the present invention, the laminated thin paper accommodating space is provided on the inner side, and the upper wall is formed in an arc shape. A container body provided with an outlet for laminated thin paper, and a pair of symmetrical open / close lids formed in an arc shape along the arc shape of the upper wall for closing and releasing the outlet, The container body is provided with a guide for guiding the opening / closing lid so that the opening / closing lid can slide in parallel substantially along the arcuate surface of the upper wall of the container body, and the opening / closing lid between the butted edges of the opening / closing lid. Is provided with a locking mechanism that holds the closing posture of the outlet, and the locking mechanism is configured to be unlockable by pressing the upper surface of the edge of the opening and closing lid, and maintains the closing position of both opening and closing lids, To the other opening / closing lid side One in which a stopper to prevent the migration is provided.

  In the storage container having the sliding opening / closing lid with the above configuration, as shown in FIGS. 1, 2, and 4A, the opening / closing lid covers the take-out port by the lock mechanism, and the laminated thin paper in the storage space is dried. While maintaining the closed position. In order to take out the laminated thin paper in the storage space from this state, the edge of one of the opening / closing lids is pressed with a fingertip or the like, and the opening / closing lid is pushed and bent. By this bending, the locked state of both the opening and closing lids is released. After the lock is released, the direction of the container body remains the same, and the edges of both the opening and closing lids are pushed open with the thumb and index finger open. By doing in this way, as shown in FIG.3, FIG.4 (B) and FIG. 5, both opening-and-closing lids slide in parallel along the arc-shaped surface of the upper wall of a container main body. This slide is smoothly achieved by the guide. When the open / close lid opens the outlet, pull out the laminated thin paper with your fingertips. Since the opening / closing lid only moves to both sides of the outlet, the opening / closing lid does not obstruct the field of view due to the orientation of the container body, making it difficult to see the outlet. Visible.

  To close the take-out port after using the laminated thin paper, from the open position shown in FIG. 3, FIG. 4 (B), FIG. Slide both open / close lids along the guide so that the open / close lids are pulled in the closing direction. At the final stage, the locking mechanism is operated by pulling slightly strongly so as to maintain the closed posture shown in FIGS. 1, 2, and 4A.

Therefore, the storage container having the slide type opening / closing lid according to claim 2 of the present invention can be unlocked by pressing one of the edges of the both opening / closing lids, and the opening / closing lid can be taken out. Since the take-out port can be opened by laterally moving in parallel, the open / close lid can be easily opened and closed with a single touch while the take-out port can be clearly seen from any side of the container body.
As a result, unlike the conventional product that keeps the open / closed lid open and the conventional product with unstable locking mechanism, the open / close lid can be easily opened and closed from either side regardless of the orientation of the storage container. At the same time, the laminated thin paper can be taken out from the outlet accurately and quickly without being obstructed by the opening / closing lid.

  Further, the storage container having the slide type opening / closing lid according to the present invention is provided with a storage space for laminated thin paper on the inside, and the upper wall is formed in an arc shape, and the upper wall is formed on the upper wall. A container body provided with an outlet for laminated thin paper, and a pair of symmetrical open / close lids formed in an arc shape along the arc shape of the upper wall for closing and releasing the outlet, The container body is provided with a guide for guiding the opening / closing lid so that the opening / closing lid can slide in parallel with the arcuate surface of the upper wall of the container body, and the opening / closing lid between the opposite edges of the opening / closing lid. There is provided a lock mechanism for maintaining the closing posture of the take-out port by the lid, and this lock mechanism is configured to be unlockable by pressing the upper surface of the edge of the open / close lid, and maintains the closed position of both open / close lids. Open and close each other A stopper for preventing the shift to the side, and a release mechanism for forcibly pressing the open / close lid in the opening direction by an elastic repulsion after the lock by the lock mechanism is released. it can.

  According to this configuration, the opening / closing lid is forcibly pushed in the opening direction by the elastic repulsive force of the release mechanism while still exhibiting the effect of the invention described in claim 1, and as a result, the unlocking The opening operation of the rear lid can be done quickly. Therefore, even when the laminated thin paper is taken out from the storage container in a hurry, it can be performed quickly and accurately with a lighter force.

Further, in the storage container having the slide type opening / closing lid according to the present invention, as described in claim 4, the guide is formed by guide rails formed on the lower left and right wall surfaces of the container body and the left and right hanging of the both opening / closing lids. It is desirable that the frame is formed by a piece provided at the lower part of the wall and fitted in the guide rail.
This is because the opening / closing operation of the opening / closing lid can be performed more accurately, quickly and smoothly.

Further, as described in claim 5, it is desirable that the upper surface of the edge of either one of the open / close lids is formed on a pressing surface that is partially roughened.
This is because the fit of the fingertip with respect to the opening / closing lid is enhanced, the catch is accurately, and the opening / closing can be performed accurately and quickly.

Furthermore, as described in claim 6, the locking mechanism includes a protrusion that bulges from the left and right center part of one opening / closing lid edge toward the upper wall side of the other opening / closing cover edge, and integrally projects. It is desirable that the engaging protrusion is provided and a locking recess that is integrally provided on the lower surface of the portion facing the central portion of the other opening / closing lid edge and opens downward.
This is because it can be provided inexpensively with a simple structure.

Further, as described in claim 7, the opening / closing lid is formed to be slightly longer than the opening width of one half in the left-right width direction of the take-out port, and opens above the take-out port in an open posture. It is desirable that the amount of lateral protrusion from the side surface of the container body is set to be approximately one third or less of the width of the opening / closing lid in the sliding direction.
This is because, unlike the conventional product, which has a large opening and closing lid, the amount of protrusion to the side is as small as possible and can be handled safely.

Furthermore, as described in claim 8, it is desirable to use wet tissue paper as the laminated thin paper.
This is because the function of the storage container having the slide type opening / closing lid according to the present invention can be most ideally used.

  Hereinafter, an embodiment in which a storage container having a slide type opening / closing lid according to the present invention is applied to a storage container for wet tissue paper will be described with reference to FIGS.

  A storage container 1 having a slide-type opening / closing lid according to the present invention includes a container main body 2 and laminated thin paper such as wet tissue formed on the central portion of the upper wall 3 of the container main body 2 (hereinafter simply referred to as wet tissue, It is an example and it is needless to say that the tissue is not limited to a wet tissue.) The P take-out port 4 and a pair of symmetrical open / close lids 5 that open and close the take-out port 4 are provided.

  The container body 2 is formed as a substantially rectangular parallelepiped using, for example, a synthetic resin such as hard polyethylene or polypropylene. As shown in FIGS. 1, 5, and 6, the bottom wall 6 of the container main body 2 is detachably fitted to the peripheral wall 7 of the container main body 2 via an uneven edge 8. The inside of the container body 2 is kept in a sealed state by the fitting of the uneven edge 8. The wet tissue P can be stored in the storage space S of the container body 2 by releasing the fitting of the uneven edge 8 and removing the bottom wall 6.

Next, the configuration of the take-out port 4 will be described based on the descriptions in FIGS. 1, 3, 5, and 6.
The central portion of the upper wall (top wall) 3 of the container body 2 is slightly recessed in a rectangular shape on the storage space S side to form the concave portion 9 integrally. And the said extraction port 4 is formed in the center of this recessed part 9. As shown in FIG. The shape of the opening is selected from various shapes such as a circle, an ellipse, a rectangle, a corrugated shape, and a cross shape (not shown) so as to extend in the longitudinal direction of the container body 2 (the depth direction in FIG. 1). In addition, the upper wall 3 of the container main body 2 is formed in a direction perpendicular to the longitudinal direction of the container main body, that is, in the width direction (the left-right direction in FIG. As a side view, it has a substantially kamaboko shape.

  As shown in FIGS. 1 to 5, the open / close lid 5 has a width of approximately two-thirds of the dimension of the container body 2 in the width direction, as clearly shown in FIGS. 1 to 5. The opening / closing lid 5 is made of a synthetic resin such as hard polyethylene or polypropylene. Each of them has an arc-shaped closing plate portion 10 whose center portion is lightly raised upward according to the shape of the upper wall 3, and is integrated downward from both ends of the closing plate portion 10 along the left and right peripheral walls 7 </ b> A of the container body 2. It is comprised from the leg part 11 suspended by. The pair of left and right open / close lids 5 can be slid by being guided by guide grooves 12 described later substantially parallel to the arcuate surface of the upper wall 3. The lateral width dimension is set so that the upper and lower lids 5 can cover the entire upper portion of the concave portion 9 when the storage container 2 is closed with the opposite edges 13 facing each other at the center in the width direction. Further, both the open / close lids 5 are configured to maintain their closed positions and to be held at their closed positions by a stopper 14 described later so as not to move to the other open / close lid 5 side. Further, a pressing surface 10A (a PUSH display portion in FIGS. 2 and 3) that is partially roughened is formed on the upper surface of the central portion of one of the edges 13 of the closing plate portion 10. This is to improve the fit of the fingertip with respect to the opening / closing lid 5 and to make it possible to perform the opening / closing accurately and quickly by accurately catching. As the form of the rough surface, a sand-like uneven shape, a plurality of convex ribs, a plurality of concave grooves, and the like can be used.

  As shown in FIGS. 1 and 5, particularly FIG. 6, a slide piece 15 is integrally provided at the lower end of the leg portion 11 so as to project inward. The slide piece 15 is slid in the guide groove 12 as an example of a guide provided in a U-shaped cross section at both sides in the longitudinal direction of the container body 2, that is, below the outer surface of the left and right peripheral walls 7A. Fits freely. The guide groove 12 is curved with substantially the same curvature in accordance with the curvature of the upper wall 3, and is approximately in the vicinity of the front and rear peripheral walls 7 </ b> B from the left and right central portions of the left and right peripheral walls 7 </ b> A of the container main body 2. It is provided over the outward flange 7D provided at the lower end. Therefore, the opening / closing lid 5 can slide in a draw door shape along the curvature of the upper wall 3 via the leg portion 11 and in the final stage of the sliding stroke. The slide ends when it abuts against the flange 7D. In this invention, the amount of protrusion on the side of the peripheral wall 7B before and after the opening / closing lid 5 at this time is approximately 3 minutes of the lateral width of the opening / closing lid 5, respectively, as shown in FIGS. It is set to about 1.

  As shown in FIG. 6, the interval K1 between the slide pieces 15 provided on both leg portions 11 of the opening / closing lid 5 is equal to or slightly wider than the interval K2 between the bottoms of the guide grooves 12, and the left and right sides of the container body 2 It goes without saying that the dimension is set to be smaller than the distance K3 between the outer surfaces of the peripheral wall 7A. In short, the slide piece 15 is formed so that the slide piece 15 can be smoothly opened and closed without being easily detached from the guide groove 12.

A lock mechanism 16 that holds the closing posture of the outlet 4 by the opening / closing lid 5 is provided between the opposite edges 13 of the both opening / closing lids 5.
As shown in FIG. 1, an enlarged portion of FIG. 1, and FIG. 5, the lock mechanism 16 includes an engagement recess 17 provided on the lower surface of one opening / closing lid 5 edge 13 (see FIGS. 2 to 4), and the other The locking projection 18 is integrally formed on the side edge 13 of the opening / closing lid 5 toward the one opening / closing lid 5 side. Both the engaging recess 17 and the locking protrusion 18 are provided at a position corresponding to the central portion of the opening / closing lid 5 in the longitudinal direction (longitudinal direction of the container body 2). The engaging recess 17 is formed by recessing the lower surface of a portion slightly inside from the edge 13 of one opening / closing lid 5 upward in an arc shape. Further, the locking projection 18 is provided with a protruding portion 19 bulging upward in an arc shape that fits into the engaging recess 17 from below at the tip. The reason why the recess 17 and the protrusion 19 are formed in an arc shape is to facilitate and lighten the lock.

The locking projection 18 and the engaging recess 17 are locked and released, that is, the opening / closing lid 5 is opened and closed as follows.
First, in order to open the opening / closing lid 5, the center portion of the edge 13 of the other opening / closing lid 5 is pressed downward with, for example, an index finger from the closed position in FIGS. 1, 2, and 4 (A). . As a result, the edge 13 is bent downward to press the locking projection 18 downward. As a result, the edge 13 is bent downward to move the locking projection 18 downward. By this pressing, the protrusion 19 of the locking protrusion 18 is released downward from the engagement recess 17. In this state, the thumb is also attached to the edge 13 of one of the open / close lids 5 and the locks are released by pulling the open / close lids 5 apart from each other so as to open both fingers. Subsequently, by pulling the both open / close lids 5 left and right, as shown in FIGS. 3, 4 (B), and 5, the recess 9, that is, the upper part of the outlet 4 is opened.

  Next, in order to close the open / close lid 5, from the state of FIG. 3, FIG. 4 (B), FIG. 5, for example, attach the thumb and index finger to the edge 13 of the pair of open / close lids 5, Pull each other towards. In the final stage of drawing, the lower surface of the one opening / closing lid 5 in front of the engaging recess 17 and the projection 19 are pushed downward by being slightly elastically deformed and pressed. When the engagement recess 17 is reached, the downward pressing force is released, whereby the protrusion 19 is fitted into the engagement recess 17 by being elastically restored and thereby locked. As a result, the opening / closing lid 5 is closed, and as shown in FIGS. 1, 2, and 4 (A), the recess 9, that is, the upper portion of the outlet 4 is closed by a pair of left and right opening / closing lids 5.

  Further, as shown in FIG. 1, between the lower surface of the opening / closing lid 5 and the upper surface of the upper wall 3 of the container body 2, the opening / closing lid 5 is allowed to bend downward, and is engaged from the engagement recess 17. The clearance 20 is configured to exist so that the protrusion 18 can be detached and the left and right sliding of the opening / closing lid 5 can be performed smoothly. The gap 20 is formed by setting the dimension of the leg portion 11 so that the lower surface of the opening / closing lid 5 is positioned slightly higher than the upper surface of the upper wall 3.

Both the open / close lids 5 maintain their closed positions, and the closed positions thereof are maintained by the stoppers 14 shown in FIG. 6 so as not to move to the other open / close lid 5 side.
The stopper 14 is configured as follows.
As shown in FIGS. 3 and 4B, particularly FIG. 6, the opening / closing lid 5 is provided at the center of the left and right peripheral walls 7 </ b> A of the container body 2 at the upper edge portion where the left and right peripheral walls 7 </ b> A are connected to the upper wall 3. A recess 21 having an L-shaped cross section is provided by being recessed from the surface of the left and right peripheral walls 7A to the inside of the container body 2 and having a predetermined length corresponding to the slide amount. Further, a piece member 22 that fits into the recess 21 is provided inside the upper portion of the leg portion 11 of each opening / closing lid 5. Accordingly, the opening / closing lid 5 is prevented from moving to the other opening / closing lid existence side by the piece member 22 coming into contact with the stepped portion 21A located on the center side in the width direction of the container body 2 of the recess 21. Is done. As a result, the opening / closing lid 5 is configured to maintain an intended closed position in a posture in which the edges 13 of the container body 2 abut each other just at the central portion of the container body 2.

  The predetermined length corresponding to the sliding amount of each opening / closing lid 5 is the moving length of the opening / closing lid 5 from the closed position shown in FIG. 1 to the open position shown in FIG. Refers to the distance from when it hits the flange 7D until the transition to the open side is prevented. Needless to say, the recess 21 needs to be substantially equal to or slightly longer than the length of the opening / closing lid 5 plus the width of the piece member 22.

Next, a second embodiment of the present invention will be described based on the description of FIGS.
In the second embodiment described below, taking into account the urgency when taking out the wet tissue P from the storage container 2, the movement of the open / close lid 5 to the open posture can be performed quickly and accurately with a lighter force. It was developed with the intention of enabling it.
The basic idea is that after the lock by the lock mechanism 16 is released, the open / close lid 5 is forcibly slid in the opening direction by the elastic repulsive force of the spring, and the opening / closing lid 5 is released after the lock is released. It was designed to be quick.

The release mechanism for forcibly sliding the opening / closing lid 5 in the opening direction by the elastic repulsion force after the lock by the lock mechanism 16 is released is constituted by a resin spring described below.
As shown in FIGS. 8 and 12, a resin spring 24 is mounted on the lower surface of the edge 23 opposite to the edge 13 of each opening / closing lid 5. When the resin spring 24 is brought into contact with the rising walls 9A before and after the recess 9 against the elastic repulsion force when the opening / closing lid 5 is closed, and the lock mechanism 16 is released from the locked state, the elastic repulsion of the resin spring 24 is achieved. The opening / closing lid 5 is opened at once by force.

  The resin spring 24 is formed by folding a thin plate-like rectangular plate spring in the center, and the two-folded portion 24 </ b> A is directed toward the concave portion 9. It is fixed by appropriate means such as a pin 25. The length of the resin spring 24 is set as appropriate, but is approximately one-half to one-third of the width of the opening / closing lid 5 in the illustrated example. Since the bi-folded portion 24A becomes a loop, when it comes into contact with the rising wall 9A before and after the concave portion 9, it moves downward along the wall 9A so as to bend well from the intermediate portion. The elastic repulsive force is accumulated by this bending. In addition, in order to allow the transition of the resin spring 24 and the bent posture when the opening / closing lid 5 is closed, a portion corresponding to the central portion in the longitudinal direction of the container body 2 outside the rising wall 9A before and after the recess 9 is provided. The upper wall 3 is partially recessed, and a recessed portion 26 is provided. The depth of the recessed portion 26 is set so that the bottom wall 26A of the recessed portion 26 is substantially at the same height as the uppermost end surface of the new wet tissue bundle stored in the storage container 2 in the illustrated example. Has been. As a material of the resin spring 24, a synthetic resin such as polyurethane or a rubber such as silicon rubber, butadiene rubber, or ethylene-propylin rubber can be used. Further, a metal spring can be used as an alternative to the resin spring.

Further, in this embodiment, a closing structure is added so that the opening / closing lid 5 is not unnecessarily opened by the resin spring 24 when the container is distributed.
Specifically, as shown in FIG. 7 and FIG. 8, a hook 27 that is integrally raised with a predetermined dimension in the longitudinal direction of the container body 2 is formed on the upper surface of the edge 13 of each opening / closing lid 5. Is provided. In addition, in order to keep the both ends 27 firmly abutting against the elastic force of the resin spring 24, a rectangular shape having a slit 28 having a width equal to or slightly longer than the overlapping dimension of the both ends 27 in the center. The spread prevention tool 29 which consists of a flat plate is provided.
Therefore, when the container is in circulation, the flanges 27 which are in a closed posture and are in contact with each other are inserted into the slits 28 of the spread prevention tool 29. By doing in this way, it can prevent well that the opening-and-closing lid 5 is opened carelessly at the time of distribution of a container.
Since the other configuration is the same as that of the first embodiment, the same reference numerals as those of the first embodiment are given and detailed description thereof is omitted.

In each of the above-described embodiments, the upper wall 3 is formed in an arc shape, and the entire storage container 2 is formed in a semi-cylindrical shape when viewed from the side. In this third embodiment, as shown in FIG. 3 is formed flat. In accordance with the flat shape of the upper wall 3, the opening / closing lid 5 is also formed in a flat shape along the horizontal direction, and the guide groove 15 is also formed in a straight line along the horizontal direction.
Also in the case of the third embodiment, when the opening / closing lid 5 is opened, the amount of protrusion from the front and rear peripheral walls 7B is the same as in the first and second embodiments, and the opened opening / closing lid 5 may be caught on the limbs. There are few, and it is easy to handle.
Since the other configuration is the same as that of the first embodiment, the same reference numerals as those of the first embodiment are given and detailed description thereof is omitted.

In each of the embodiments described above, it is desirable that the lock strength of the lock mechanism 16 can be selected in various strengths as required. The example shown in FIG. 13 shows a structure when it is desired to tighten strongly unlike the above-described embodiments. The catch between the engaging recess 17 and the locking projection 18 is strengthened to make it difficult to come off.
Specifically, the edge 13 side of the engaging recess 17 is a substantially vertical surface, and the side of the locking projection 18 facing the main body side of the opening / closing lid 5 is made to correspond thereto. It is formed almost vertically according to the vertical surface. Engagement between the engaging recess 17 and the locking protrusion 18 becomes strong, and strong closing is possible.

Further, as shown in FIG. 14, a rising material 30 made of a flexible material such as a rubber material or a synthetic resin material can be provided around the recess 9. The rising height is such that the upper edge of the rising wall 30 is just in contact with the lower surface of the opening / closing lid 5 when the opening / closing lid 5 covers the recess 9. In other words, it is approximately the same size as the gap 20 formed between the lower surface of the opening / closing lid 5 and the lower upper wall 3.
In order to unlock the lock mechanism 16, the edge 13 of the opening / closing lid 5 is pressed and bent downward. However, since the rising wall 30 is flexible, the rising wall 30 bends itself to be below the opening / closing lid 5. The release of the lock is performed smoothly.

In the first embodiment, an example in which the pressing surface 10A is formed to be a rough surface is shown. However, instead of this, a ridge shown by 27 can be adopted in the second embodiment.
The installation position is the same as the position where the pressing surface 10 </ b> A is provided, and is provided by being integrally raised on the upper surface of the central portion of the edge 13.
When the opening / closing lid 5 is opened / closed, the opening / closing lid 5 can be opened / closed more accurately by picking the hook 27 with a fingertip.
Moreover, also in the embodiment of the horizontal slide shown in FIG. 13, the resin spring 24 shown in Embodiment 2 of FIGS. 7 to 11 can be applied. In this case, needless to say, the expansion preventing tool 29 is naturally required.

  In each of the above embodiments, the opening amount of the opening / closing lid 5 is described as the entire upper area of the recess 9. This is because the wet tissue P is the most easily opened and is the ideal opening amount. However, in the present invention, the optimum opening amount is not necessarily concerned. Since the laminated thin paper P such as wet tissue can be easily pulled out as long as the opening amount is sufficient to open at least the upper portion of the extraction port 4, at least the extraction is performed as a range in which the wet tissue P can be efficiently extracted with a minimum opening amount. Needless to say, an amount for opening the mouth 4 is necessary. In the present invention, the range of the opening amount includes a range extending from the upper portion of the outlet 4 to the upper portion of the concave portion 9, and is appropriately set within this range. Is desirable.

  The storage container having the slide-type opening / closing lid according to the present invention described above is not limited to simply being applied to a wet tissue paper storage paper container, and requires one-touch opening / closing of various soft material storage containers and other various containers. Needless to say, it can also be applied to the field.
