Description

The present invention relates to a storage case that can store a stack of sheet-like materials and allows the sheet-like materials to be removed from the top.

A storage case is known that has a cover that can be opened and closed relative to the case body so that the laminate inside the storage case can be replaced (see, for example, Patent Document 1).

Patent Document 1 discloses a configuration in which a convex part is formed on the body and a concave part is formed on the lid into which the convex part fits, with the opening of the concave part being slightly narrower than the maximum width of the convex part, so that the convex part will not come out of the concave part unless a certain amount of force is applied. This makes it difficult for the lid to come off the body.

Registered Utility Model No. 3030806

However, the description in Patent Document 1 is that when the protrusion is engaged with the recess, a certain amount of force is applied to release the engagement of the protrusion with the recess. Therefore, if the lid is opened and closed multiple times, the protrusion and recess may become deformed, deteriorating the locking function.

Therefore, the present invention aims to provide a storage case with a simple structure whose locking function does not deteriorate even when the cover is opened and closed.

In order to achieve the above object, the storage case of the present invention is a storage case capable of storing a stack of sheet-like materials and removing the sheet-like materials from the top, and is characterized in that it comprises a box-shaped main case having an opening at the top, a cover connected to the rear wall of the main case and movable between a closed position in which the opening is closed and an open position in which the opening is open, a protrusion provided on the front wall of the main case that protrudes upward, a recess provided on the protrusion that is recessed in the in-plane direction of the front wall, and a protrusion provided on the cover that hooks onto the recess in the closed position, and that the protrusion is pressed in the out-of-plane direction of the front wall to release the hooking of the protrusion onto the recess.

The storage case of the present invention, configured in this way, has a simple structure and can prevent the locking function from deteriorating even when the cover is opened and closed.

Below, an embodiment of a storage case according to the present invention will be described based on Example 1 shown in the drawings.

In the first embodiment, the present invention is applied to a storage case that contains soft packages in which tissue papers are stacked.

[Storage case configuration]
FIG. 1 is a perspective view showing a storage case of Example 1 with the cover in a closed position. FIG. 2 is an exploded perspective view showing the storage case of Example 1 and a stack of sheet-like materials. FIG. 3 is a perspective view showing a storage case of Example 1 with the cover in an open position. FIG. 4 is a perspective view showing a storage case of Example 1 with the cover between the open position and the closed position. FIG. 5 is a perspective view showing a storage case of Example 1 with the cover in a closed position. FIG. 6 is a perspective view showing a storage case of Example 1 with the cover in a closed position. The configuration of the storage case of Example 1 will be described below. The front-to-back direction of the storage case is defined as the front-to-back direction D1, the left-to-right direction is defined as the left-to-right direction D2, and the up-to-down direction is defined as the up-to-down direction D3.

As shown in FIG. 1, the storage case 1 includes a main case 20 and a cover 10, and stores a soft package 5 that contains a stack of tissues 6 as a sheet-like object. The main case 20 has an opening 11a at the top that allows the tissues 6 to be removed.

The decorative paper 8 is attached to the surfaces of the main case 20 and the cover 10 with adhesive.

As shown in FIG. 2, the main body case 20 is designed to house the soft package 5.

(Main body case)
The main body case 20 can be formed from thick paper such as mount paper or cardboard. As shown in Fig. 3, the main body case 20 is formed by attaching an outer case 20B to an inner case 20A by, for example, an adhesive.

The inner case 20A is formed into a rectangular box shape with a bottom 21, a front 22, a rear 23, and a side 24, and an opening at the top.

The bottom 21 is formed in a rectangular plate shape. The front portion 22 is formed rising upward from the front edge of the bottom 21. The rear portion 23 is formed rising upward from the rear edge of the bottom 21. The side portion 24 is formed rising upward from the side edge of the bottom 21.

The outer case 20B is formed into a frame shape that surrounds the outer periphery of the inner case 20A with a front frame 25, a rear frame 26, and a side frame 27. The front portion 22 and the front frame 25 form the front wall 122 of the main case 20. The rear portion 23 and the rear frame 26 form the rear wall 123 of the main case 20. The side portion 24 and the side frame 27 form the side wall 124 of the main case 20.

The front frame 25 has a protruding portion 25a that protrudes upward near the center in the left-right direction D2. The protruding portion 25a is formed in an elliptical shape when viewed from the front, and has a recess 25b at the base. The protruding portion 25a can have a width that is approximately the same as the width of the thumb M as a finger. The protruding portion 25a is formed at a position lower than the height of the front portion 22.

The recess 25b is recessed in the left-right direction D2 so that the width of the protrusion 25a is narrowed. In other words, the recess 25b is recessed in the in-plane direction of the front wall 122. The recess 25b can be formed in an R-shape when viewed from the front.

The rear frame 26 is formed at a lower height than the rear portion 23. The side frames 27 are formed at a lower height than the side portions 24.

(cover)
The cover 10 can be formed from thick paper such as mount board or cardboard.

As shown in FIG. 4, the cover 10 is formed into a box shape with an opening at the bottom, with a top plate 11, a front plate 12, a rear plate 13, and side plates 14. The rear plate 13 of the cover 10 is connected to the rear wall 123 of the main body case 20, allowing the cover 10 to move between a closed position P1 (see FIG. 1) where the opening is closed, and an open position P2 (see FIG. 2) where the opening is open.

The top plate 11 is formed in a rectangular plate shape. The top plate 11 has an opening 11a for removing the tissue paper 6.

The front plate 12 is formed by extending downward from the front edge of the top plate 11. The front plate 12 has a notch 12a that is concave upward near the center in the left-right direction D2. The notch 12a is formed in an elliptical shape when viewed from the front, and has a protrusion 12b at its base. The notch 12a is formed in a shape that corresponds to the protrusion 25a. The protrusion 12b is formed in a shape that corresponds to the recess 25b.

As shown in FIG. 1, when the cover 10 is in the closed position P1, the storage case 1 configured in this manner is locked by the protrusion 12b being caught in the recess 25b. Therefore, the cover 10 can be maintained in the closed position P1.

As shown in FIG. 6, when the cover 10 is in the closed position P1 and the protrusion 25a is pressed backward (in the pressing direction F), the protrusion 12b is released from the recess 25b, and the lock is released. Therefore, the cover 10 can move from the closed position P1 to the open position P2.

As shown in FIG. 6, the storage case 1 has a slit 16 at a corner 15 formed by the top plate 11 and the front plate 12. The slit 16 is formed as a hole penetrating the cover 10. The slit 16 is formed near the center in the left-right direction D2.

The width W1 of the slit 16 can be in the range of 20% to 25% of the width W2 of the cover 10 in the left-right direction D2. This makes it possible to prevent the protrusion 12b from being pulled by the peripheral edge of the front plate 12. This makes it possible to prevent the protrusion 12b from warping.

If the width W1 of the slit 16 is made narrower than 20% of the width W2 in the left-right direction D2 of the cover 10, the protrusion 12b will be pulled toward the periphery of the front plate 12, causing warping of the protrusion 12b. On the other hand, if the width of the slit 16 is made wider than 25% of the width W2 of the cover 10 in the left-right direction D2, the strength of the cover 10 cannot be maintained.

As shown in FIG. 6, the corners 15 are curved in the pressing direction F so that the slits 16 formed near the center in the left-right direction D2 are formed at a position set back by a length L (e.g., 0.3 mm) in the pressing direction F. In other words, the front panel 12 is curved in the pressing direction F.

[Configuration of the biasing means]
Fig. 7 is a perspective view showing an expanded state of the urging means of Example 1. Fig. 8 is a perspective view showing a compressed state of the urging means of Example 1. The configuration of the urging means of Example 1 will be described below.

As shown in FIG. 2, the main body case 20 contains a biasing means 40. The soft package 5 is stored in the main body case 20 via the biasing means 40. The soft package 5 is stored in the main body case 20 in a state where it is biased upward by the biasing means 40.

As shown in FIG. 7, the biasing means 40 is composed of an upper support portion 41, a lower support portion 42, a bent portion 43, and an elastic member 45.

The upper support section 41, the lower support section 42, and the folding section 43 can be formed, for example, from cardboard, resin, etc. The upper support section 41, the lower support section 42, and the folding section 43 can be formed by pressing and folding a sheet of cardboard, resin, or other sheet material.

The upper support portion 41 and the lower support portion 42 are large enough to support the soft package 5. The folding portion 43 is connected to the upper support portion 41 and the lower support portion 42.

The bending portion 43 is formed in a substantially rectangular frame shape in a plan view, and can be bent so that the center portion in the vertical direction D3 protrudes outward. The bending portion 43 allows the biasing means 40 to move between an extended position in which the upper support portion 41 moves away from the lower support portion 42, and a contracted position in which the upper support portion 41 moves toward the lower support portion 42.

A rubber band serving as the elastic member 45 is provided in a stretched state in the center of the bent portion 43 in the up-down direction D3. When the biasing means 40 moves from the stretched position toward the contracted position, the biasing means 40 biases the upper support portion 41 upward by the elastic force of the elastic member 45.

[Function of the storage case]
The operation of the storage case 1 of the first embodiment will be described below.

The storage case 1 of the first embodiment stores a stack of sheet-like objects (tissues 6) and allows the sheet-like objects (tissues 6) to be removed from the top. This storage case 1 includes a box-shaped main case 20 with an opening at the top, a cover 10 connected to the rear wall 123 of the main case 20 and movable between a closed position P1 where the opening is closed and an open position P2 where the opening is open, a protrusion 25a protruding upward on the front wall 122 of the main case 20, a recess 25b recessed in the in-plane direction of the front wall 122 on the protrusion 25a, and a protrusion 12b on the cover 10 that hooks onto the recess 25b in the closed position P1. By pressing the protrusion 25a in the out-of-plane direction of the front wall 122, the hooking of the protrusion 12b onto the recess 25b is released (FIG. 3).

As a result, in the closed position P1, the convex portion 12b is caught in the concave portion 25b, resulting in a locked state. Therefore, the cover 10 can maintain the closed position P1. On the other hand, when the protrusion 25a is pressed, the convex portion 12b is released from the concave portion 25b, resulting in the unlocked state. Therefore, the cover 10 can move from the closed position P1 to the open position P2.

As a result, it is possible to prevent the convex portion 12b from being forcibly released from the locked state in which the convex portion 12b is caught in the concave portion 25b, and to prevent damage to the convex portion 12b and the concave portion 25b. Therefore, it is possible to provide a storage case 1 with a simple configuration in which the locking function does not deteriorate even when the cover 10 is opened and closed.

In the storage case 1 of the first embodiment, the protrusion 25a has a width that is approximately the same as the width of a finger (thumb M) (Figure 3).

This ensures that the width of the protrusion 25a is sufficient to allow pressing with a finger (thumb M), while increasing the amount of deformation of the recess 25b in the pressing direction F when the protrusion 25a is pressed. Therefore, by pressing the protrusion 25a with a finger, the locked state caused by the protrusion 12b getting caught in the recess 25b can be easily released.

In addition, by making the protrusion 25a approximately the same width as a finger (thumb M), it is possible to visually indicate that the protrusion 25a is the part to be pressed by the finger (thumb M). Therefore, the user of the storage case 1 can easily move the cover 10 from the closed position P1 to the open position P2.

In the storage case 1 of the first embodiment, a slit 16 is provided at the corner 15 between the top plate 11 and the front plate 12 of the cover 10 (Figure 6).

The protrusion 12b is located away from the periphery of the cover 10. When the adhesive applied to the cover 10 hardens or when the moisture contained in the cover 10 evaporates, a pulling force acts in the direction toward the periphery of the cover 10. This may cause the protrusion 12b to warp. If this happens, the locked state caused by the protrusion 12b getting caught in the recess 25b will be released, and the cover 10 will not be able to maintain the closed position P1.

In Example 1, by providing slits 16 at corners 15, it is possible to prevent protrusions 12b from being pulled by the peripheral edge. This makes it possible to prevent warping of protrusions 12b.

In the storage case 1 of the first embodiment, the corners 15 are curved in the pressing direction F (Figure 6).

This allows the front plate 12 of the cover 10 to bend, forming the protrusion 12b to retract in the pressing direction F. This prevents warping of the protrusion 12b.

The storage case 1 of the first embodiment is provided with a biasing means 40 on which the stack is placed and which biases the stack upward (FIGS. 7 and 8).

This allows the biasing means 40 to bias the stack upward. Therefore, even when the sheet-like objects (tissues 6) are removed from the storage case 1 and the amount of the stack decreases, the stack can be biased upward. As a result, the sheet-like objects (tissues 6) can be easily removed from the storage case 1 without being affected by the amount of the stack.

The storage case of the present invention has been described above based on Example 1. However, the specific configuration is not limited to this Example, and design changes and additions are permitted as long as they do not deviate from the gist of the invention as defined by each claim in the scope of the claims.

In the first embodiment, the storage case 1 is shown as having a slit 16 at the corner 15 formed by the top plate 11 and the front plate 12. However, the storage case does not have to have a slit.

In the first embodiment, the corner 15 is curved in the pressing direction F. However, the corner may be formed so as to extend straight in the left-right direction D2 without being curved.

In the first embodiment, the soft package 5 is stored in the main body case 20 via the biasing means 40. However, the soft package 5 may be stored in the main body case 20 without using the biasing means 40.

In the first embodiment, decorative paper 8 is attached to the surfaces of the main case 20 and the cover 10. However, decorative paper may not be attached to the surfaces of the main case and the cover.

In Example 1, an example was shown in which the present invention is applied to a storage case 1 that stores a soft package 5 containing tissue paper 6 in a stacked state. However, the present invention can also be applied to a storage case that stores a soft package containing paper towels or kitchen paper in a stacked state. The present invention can also be applied to a storage case that stores a laminate of paper towels or kitchen paper that is not contained in a soft package.
