Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 TECHNICAL FIELD The present invention relates to a container for storing sanitary goods such as an infant wipes and the like, and particularly to a structure of a take-out part thereof.

[0002]

[Prior art]

 So-called wet paper is used to keep the ass clean after the infant changes diapers. This wet paper must be stored in a sanitary container because it must be stored in a sanitary manner. This container is designed to be used by opening the lid as necessary and extracting wet paper one by one from a small hole formed on the upper surface of the container. For this reason, the wet paper container has a structure including a main body having an opening formed in the top plate and a closing plate having an outlet for taking out the wet paper.

[0003] A conventional container is manufactured by bonding the main body and the closure plate by bonding the lower surface of the closure plate to the outer surface of the top plate of the main body. Therefore, the conventional container has a structure in which a closing plate is further provided on the upper surface of the box-shaped main body. However, the conventional container having such a structure has a problem that an object hits or catches on the closing plate during transportation or handling. As a result, the closing plate was damaged, and the function of the sealing mechanism and the outlet could not be achieved.

[0004] On the other hand, if the outlet formed in the closing plate of the container is left open as it is, moisture is diffused from a gap between the outlets, and the contents such as wet paper are dried. For this reason, the container is provided with a lid to close the outlet. Most conventional lids are made of plastic and have a means for sealing the outlet. For example, a first cylindrical body is provided around the outlet, and a second cylindrical body having an inner diameter substantially equal to the outer diameter of the first cylindrical body is provided on the lid. In some cases, when closed, the outer wall of the first cylindrical body is inserted into contact with the inner wall of the second cylindrical body in contact with the inner wall of the second cylindrical body to form a sealed state. In some cases, a projection formed on the free end side of the lid is designed to lock when the lid is closed. However, in order to form a sealed state using these conventional containers, it is necessary to further apply force after rotating the lid and placing it on the outlet. Also, when opening the lid, the outlet is often not opened unless the lid is pulled strongly. For this reason, an excessive force was applied to the container body, which caused damage to the body and damage to the closing plate.

[0005]

[Problems to be solved by the invention]

 The present invention has been made in view of such a background, and an object of the present invention is to provide a container which is not easily damaged during transportation and handling. In particular, it is an object of the present invention to provide a container having a structure in which a closing plate fixed to a container body is not easily damaged.

Another object of the present invention is to provide a container that can form a sealed state without applying excessive force. Further, another object of the present invention is to provide a container which can be opened and a take-out opening opened without applying excessive force. Another object of the present invention is to make a container having these functions from a relatively inexpensive material.

[0010]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a container 1 for storing wet paper to which the present invention is applied. The container 1 has a substantially rectangular parallelepiped main body 9 including a top plate 3, four side plates 5, and a bottom plate 7, and a closure provided in an opening 11 formed in the top plate 3 of the main body 9. A plate 13. It is preferable that both the main body 9 and the closing plate 13 are made of cardboard having a certain strength.

A cover 15 is provided on the top plate 3 of the main body 9, and the cover 15 is rotatably connected to the top plate 3 around one long side of the opening 11 as a rotation axis. I have. In the present embodiment, when the opening 11 is formed, a part of the top plate 3 cut out from the top plate 3 constitutes the lid 15, but instead of this, the opening 11 is formed in advance. Alternatively, the lid 15 may be formed by using another paper material, and the lid 15 may be rotatably mounted around the opening 11. The embodiment in which the lid 15 is attached to the upper surface of the closing plate 13 instead of the top plate 3 is also included in the scope of the present invention.

A locking projection 19 is formed at the center of the free end 17 of the lid 15. As shown in FIGS. 4 and 5, the locking projection 19 is shaped and dimensioned so that it can be locked to the lower surface of the edge 21 around the opening 11 when the lid 15 is closed. Have. As another embodiment of the present invention, the free end 17 of the lid 15 may extend to the opening 11 without forming the special locking projection 19. As shown in FIG. 5, the locking projection 19 is only slightly locked on the edge 21 of the opening 11, so if the end 22 of the edge 21 is pushed from above in the state of FIG. The locking state of the locking projection 19 is released. Such a locking structure of the lid by the locking projection 21 is excellent in that the structure is simple, and it can be easily and inexpensively manufactured.

In another aspect of the present invention, as shown in FIG. 6, a lid stopper 20 is formed on the upper surface of the closing plate. The lid stopper 20 has such a shape and dimensions that the locking projections 19 of the lid 15 can be locked on the upper surface side when the lid 15 is closed (see FIG. 7A). The lid stopper 20 is fixed to the upper surface of the closing plate with an adhesive S or the like. The closing plate is provided with an unlocking concave portion 36, which is used to release the locking state of the locking projection 19 by the lid stopper portion 20. This provides a space into which the part 20 and the locking projection 19 enter. That is, when the closed state is released, as shown in FIG. 7A, the end of the lid stopper 20 is pushed in from the direction D, so that the locking projection 19 is locked by the lower surface of the lid stopper. Cancel. When released, as shown in FIG. 7 (b), the locking projection 19 moves in the direction E by the return force of the lid itself and the return member 37.

In order to maintain the closed state of the lid 15, various conventionally known methods such as providing a hook-and-loop fastener or an adhesive tape that can be used frequently on the lid 15 and the top plate 3 are applied. You can also. In the closed state, the contact surface between the lid 15 and the top plate 3 may be configured to have the same shape, so that a closed state with a higher degree of sealing can be formed. For example, the lid 15 and the top plate 3 may be configured in an uneven shape so that the unevenness engages in the closed state to improve the airtightness. As shown in FIG. 1 and the like, a film 26 having high adhesion is adhered to the lower surface 23 of the lid 15 in a substantially rectangular frame shape. The operation of the film 26 will be described later.

Next, the closing plate 13 will be described. The closing plate 13 is for closing the opening 11 of the main body 9 and has a rectangular shape slightly larger than the opening 11 as shown in FIG. As shown in FIGS. 2, 3 and 8, the closing plate 13 is fixed to the inner surface side of the top plate 3 of the main body 9 using heat sealing or an appropriate adhesive S. By fixing the closing plate 13 inside the container in this way, the closing plate 13 is less likely to be peeled off and less likely to be damaged as compared with the case where the closing plate 13 is fixed outside the container. Therefore, the sanitary environment in the container 1 can be more reliably maintained. Although not shown in the figure, when a film with high adhesion is provided on the lower surface of the lid and the closing plate, the closing plate uses heat sealing or an appropriate adhesive on the outer surface side of the top plate. May be fixed.

In the center of the closing plate 13, there is formed a central recess 24 which is one step lower than the surface 27 of the closing plate 13. A take-out port 25 for drawing out the wet paper W from the inside of the container 1 is formed in the center of the central concave portion 24. In order to maintain the sanitary environment in the container 1 and maintain the wetness of the wet paper W, it is preferable that the take-out port 25 be a slit or a small hole as small as possible.

Around the central recess 24, a convex portion 29 is formed in a substantially rectangular frame shape. The frame shape of the convex portion 29 substantially matches the frame shape of the film 26 attached to the lower surface of the lid 15 described above. The upper surface of the convex portion 29 is at the same level as the surface 27 of the closing plate 13, and a film 33 having high adhesion is adhered to the upper surface along the shape of the convex portion 29. As shown in FIG. 4, when the lid 15 is closed, the film 26 on the lower surface of the lid is in close contact with the film 33 on the upper surface of the convex portion, and the environment inside the central recess 24 is reduced to the outside of the convex portion 29. Can be isolated from the environment. This makes it possible to maintain the sanitary environment of the wet paper W next to be taken out in the central recess 24 and the wet paper W in the container 1, and it is possible to maintain the wetness of the wet paper W.

A peripheral concave portion 35 is formed around the convex portion 29 along the outer periphery of the convex portion. Each part of the peripheral recess 35 extending in a direction orthogonal to the longitudinal direction of the container 1 stores a return member 37. Since the peripheral concave portion only needs to be able to accommodate the return member 37, a rectangular concave portion slightly larger than the return member 37 may be provided by the number of the return members 37.

As shown in FIG. 9, the return member 37 of the present embodiment is a paper molded product 39 having a return force obtained by folding thick paper into two. The two-fold paper molded article 39 has a tendency to always return to a stretched state (see FIG. 9) from a contracted state (see FIG. 10) folded at an acute angle. In the contracted state of FIG. 10, the height h of the paper molded product 39 is smaller than the depth dimension of the peripheral concave portion 35, and in the extended state of FIG. 9, the height H of the paper molded product 39 is the depth of the peripheral concave portion 35. Larger than the size. Further, when the paper molded article 39 returns from the contracted state to the expanded state, the paper molded article 39 has a sufficient restoring force to lift the lid 15 upward. Therefore, when the locking projection 21 is not locked to the edge 19 of the opening 11, the lid 15 is lifted by the returning force of the paper molded product 39, and the top plate 3 of the main body 9 and the lid 15 are closed. A gap can be formed between the free end 17 and the free end 17 so that a human finger can enter.

The position where the paper molded article 39 is disposed is preferably as close as possible to the axis of rotation of the lid 15 so that the lid 15 is greatly opened even if the paper molded article 39 is slightly extended. Further, the paper molded product 39 is not limited to the inside of the peripheral recessed portion 35, but is fixedly arranged in the central recessed portion 24 with an adhesive or the like, or a portion of the convex portion 29 is recessed, and It may be arranged. In the present embodiment, two paper molded products 39 are arranged. However, if the lid 15 is not sufficiently opened only by the return force of the two paper molded products 39, the additional paper molded products 39 are further depressed around the periphery. It may be arranged in the portion 35 or in the central recess 24 or the like.

In this embodiment, the paper molded product 39 obtained by folding thick paper into two is used as the return member 37. However, as shown in FIG. 11, the paper is formed by folding the paper so as to repeat the mountain fold and the valley fold. A bellows-shaped paper molded product 41 may be used. In addition, instead of paper, a plastic sheet may be folded in the same manner to form a molded product having a restoring force, and this may be used as a returning member. A member may be used as the return member 37.

The container 1 of the present invention has the above-described structure, and the use state of the container 1 of the present invention will be described below. As shown in FIG. 4, the container 1 usually has a lid 15 closed. At this time, as shown in FIG. 5, the locking projection 19 of the lid 15 is locked to the edge 21 of the opening 11, so that the lid 15 can be kept closed. As shown in a partially enlarged view in FIG. 4, when the lid 15 is closed, the film 26 on the lower surface of the lid 15 and the film 33 provided on the closing plate 13 come into close contact with each other, so that the central recess is formed. The part 24 is isolated from the outside world, and a sanitary environment is maintained. Further, at this time, since the paper molded product 39 is pressed from above by the lid body 15, it is in a greatly bent state as shown in FIG.

When removing the wet paper W from the container 1, as shown by an arrow in FIG. 5, the end 22 of the edge 21 is pushed in from above to release the locking state of the locking projection 19. . In the case of the embodiment shown in FIG. 7, as shown by an arrow D in FIG. 7B, the end of the lid stopper 20 is pushed in from above to release the locking state of the locking projection 19. As a result, the lid 15 is lifted by the force of the paper molding 39 to return to the state shown in FIG. 9, and a gap is formed between the top plate 3 and the free end of the lid 15. If the lid 15 is pushed up with a finger in this gap, the lid 15 can be easily opened. In this state, the wet paper W can be pulled out from the outlet 25.

[0024]

[Effect of the invention]

 As described above, according to the present invention, since the closing plate is fixed to the inner surface of the top plate of the main body from the inside of the main body, the closure plate is less likely to be peeled and damaged than when the closing plate is fixed from the outside. Hard to receive. Therefore, the sanitary environment in the container can be more reliably maintained. In addition, a film having adhesiveness is provided around the outlet on the upper surface of the closing plate, and a film that can be in close contact with the film is provided on the lower surface side of the lid at a position corresponding to the film provided on the closing plate. If the closure plate is closed, the sanitary environment in the central recess and the container can be maintained from the outside when the closure plate is closed. At the same time, it is possible to prevent the central recess and the wet paper in the container from drying.

In addition, since the return member having a tendency to always return from the contracted state to the extended state is stored in the recessed portion of the closing plate, the lid is lifted by the restoring force of the return member, and the lid is easily opened. be able to. Further, if the return member is provided on the side closer to the rotation axis of the closing plate, the lid can be lifted and opened greatly even if the return member is slightly extended and restored. Further, if a plurality of return members are provided on both sides of the take-out opening as a center, the force for lifting the lid increases, and the lid can be lifted with certainty.

Also, if the return member is a paper molded product formed by folding paper and the paper molded product has a tendency to return from the contracted state to the expanded state, the paper molded product is also associated with the container. It can be discarded as combustible material, or it can be treated with paper resources as it is in the recycling process. Also, if the paper molding is obtained by folding the paper in two or by alternately repeating the mountain fold and the valley fold, the paper can be easily formed and the manufacturing cost can be reduced. . Conventional plastic containers use springs or elastic rubber to open the lid automatically, but the structure for receiving them is relatively complex, which complicates the manufacturing process and reduces yield. Had become a factor. The present invention has solved such a problem.

A locking projection is formed on the free end side of the lid, and the locking projection may have a structure capable of locking to the lower surface of the edge of the top plate when the lid is closed. In this case, the closed state of the lid can be easily maintained, and the structure can be easily manufactured. In addition, since the container is entirely made of paper except for the film, it can be disposed of together with normal combustible waste. In addition, no toxic gas is generated even when burned, and recycling is possible. Therefore, it is possible to provide products that are suitable for recent markets with a strong ecological orientation.
