Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly stores a large number of sheets, such as cosmetic cotton and paper napkins, and sheets of food and the like packed in thin bags such as laver and tea packs. The present invention relates to a packaging container which can be individually taken out one by one.

[0002]

2. Description of the Related Art A packaging container in which a large number of cosmetic cottons called cotton puffs are stored and can be taken out one by one as required, without providing any special structure in a box-shaped container. A variety of forms are available, including packaging containers that are sequentially removed from the top opening. For example, Japanese Utility Model Laid-Open No. 48-50280 proposes a cotton case for cosmetics in which a raised bottom plate provided with a protrusion at a position corresponding to the guide groove is mounted in a container having a guide groove formed at a position facing the side wall. ing. In this cosmetic cotton case, the protrusions of the upper bottom plate protruding from the side wall of the container are lifted by hand, so that one by one can be taken out from the opening at the upper end of the container even if the number of stored cotton is small.

In Japanese Utility Model Application Laid-Open No. 62-191679, an L-shaped middle plate is inserted into an outer box, and a cotton puff or the like is placed on a support bottom of the middle plate. There has been proposed a storage case in which the upper portion of the middle plate is protruded. In this storage case, when the upper portion of the middle plate in the protruding state is pulled up, the cotton puff placed on the middle plate support bottom is also lifted up. Therefore, even if the remaining amount is small, the cotton puff is provided at the upper edge of the outer box. Cotton puffs can be taken out one by one from the opening.

Further, in Japanese Utility Model Laid-Open No. 50-40489, a push plate is provided which slides up and down in the container, and the push plate is pressed upward by a spring using a spring, so that the contents are taken out from the upper end outlet hole of the container. Have been proposed which can take out small items one by one.

Further, Japanese Patent Application Laid-Open No. 6-99970 proposes a packaging container for cotton puffs in which cotton puffs can be taken out one by one from the bottom of a suspended container.

[0006]

However, the above-mentioned box-shaped container which has been generally used in the prior art and which is sequentially taken out from the upper opening has a drawback that it is difficult to take out the remaining amount when the remaining amount is small. In the case of the cosmetic cotton case and the storage case using the L-shaped middle plate, since there is no means for holding the position of the raised bottom plate and the middle plate, it is necessary to lift the raised bottom plate and the like at the time of removal. It was complicated.

On the other hand, in the above-mentioned container for small articles, since the cotton puff or the like placed on the push plate is always pressed against the upper hole of the container by the spring, there is no complicated operation for taking out. However, in practice, it is difficult to set and adjust the pressing force of the spring, so that it is not practical. Further, the cotton puff packaging container has a drawback that the installation place is restricted due to the structure of the hanging container.

In view of these circumstances, the present invention provides a packaging container which has a simple structure and which can reliably take out sheet sheets one by one while keeping the number of parts to a minimum and keeping manufacturing costs low. The purpose is to provide.

[0009]

According to the present invention, in order to solve the above-mentioned problems, the present invention has a size capable of accommodating a large number of sheets in a stacked manner, has an outlet on an upper surface, and is provided on an opposing side wall in a vertical direction. The container body has a slit-shaped guide elongated hole, and a lift plate provided with a guide projection protruding from a side wall at a position corresponding to the container body guide elongated hole, which can be inserted into the container body and raised and lowered. In the sheet-shaped packaging container, a large number of locking ribs are protruded at intervals on the inner surface of the container body side wall along the guide long holes, while the locking ribs are formed near the guide protrusions on the lift plate side wall. A stopper claw is provided, and a slit hole is formed in the inside of the lift plate side wall, so that the catch claw of the lift plate side wall is caught by a catch rib on the inner surface of the container body side wall. So that the direction position can be fixed Form was.

In the packaging container according to the present invention as well, if the sheet-like material is sequentially taken out from the upper surface outlet and the remaining amount is reduced, it becomes gradually difficult to take out the sheet material from the upper surface outlet. Therefore, when the lift plate guide protrusion protruding from the side wall of the container body is pressed between, for example, the index finger and the thumb of the right hand, the side wall surface of the lift plate is elastically deformed inward due to the presence of the slit hole. The hooking claw is disengaged from the hooking rib on the inner surface of the side wall of the container body, and the hooking of both is released. If you lift the lift plate as much as possible and then release your hand, the side wall surface of the lift plate will be restored, and the hook claw will re-engage with the hook rib located above, so the position of the lift plate will be fixed Is achieved. As the lift plate is raised, the position of the sheet-like material placed on the lift plate also rises,
This facilitates removal from the container body upper surface outlet.

According to the second aspect of the present invention, in the individual sheet packaging container for the sheet-like material according to the first aspect of the present invention, a support projection is provided on a side wall of the lift plate on which the hooking claw is not formed. The support projection was formed so as to contact the inner wall of the container body.

In the operation of raising and lowering the lift plate, the operation often becomes difficult because friction occurs between the lift plate side wall surface and the container body side wall surface because the lift plate side wall surface slides. If support projections are provided on the lift plate side walls,
Since only the top of the support protrusion contacts the inner wall of the container body,
The frictional resistance can be reduced to a minimum as compared with the case where the entire surface of the lift plate side wall is in contact, and a smooth ascent / descent operation can be performed. The position at which the support projection is provided is arbitrary, but it is sufficient to provide about two places at appropriate intervals on the wall surface on which the lift plate guide projection and the slit hole are not provided.

As described above, in the packaging container according to the present invention, the side wall surface of the lift plate is formed so as to be elastically deformable inward by providing the slit hole, and has a structure that functions as a plate spring. Therefore, in order to ensure the durability of the side wall surface, it is desirable that the lift plate has a certain thickness. In this case, the support protrusions projecting from the side wall of the lift plate may be formed in a plurality in the vertical direction or in a short rail shape continuous in the vertical direction at each position. When the lift plate is given a thickness as described above, the lift plate is less likely to be inclined when the lift plate is raised and lowered, and a stable vertical movement can be performed while maintaining a horizontal state.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a single-piece package according to the present invention. FIG. 1 is a partially cutaway perspective view showing an example of an individually taken out packaging container according to the present invention, FIG. 2 is a longitudinal sectional view of a container body in the packaging container, and FIG. It is. The packaging container of the illustrated example includes a container body 1,
It is roughly composed of a lift plate 2 inserted into the container body 1 and a lid 3 capable of closing an upper opening of the container body 1. Each member may be obtained by injection molding of a synthetic resin such as polypropylene or the like, and may have a skeleton specification in which the inside of the packaging container is visible from the outside or a solid specification in which the inside of the packaging container is not visible from the outside.

The container main body 1 is formed to have a size capable of accommodating a large number of sheet-like objects typified by cosmetic cotton, and may be appropriately sized according to the object to be accommodated. The container body 1 of this example has a tubular shape having a substantially rectangular cross section in accordance with the outer shape of the cotton wool.
Front cover divided vertically in about one-half part
11 and the rear cover 12
It is formed by fitting at 3 and 13. Container body 1
The upper surface of the cover 3 is an opening 14 which is open almost entirely, and the lid 3 is joined to the upper end of the rear cover 12 via a hinge so as to be openable and closable.

The container main body 1 is provided with slit-shaped guide slots 15, 15 in the vertical direction on the opposing side walls, and extends along the respective guide slots 15, 15 in the direction perpendicular to the axis. A large number of hooking ribs 16a and 16b are provided at intervals. In the present example, the front-side hooking rib 16a is made longer, but this is from the viewpoint of increasing the strength of the container body 1, and it is not necessary to make it longer.
The positions where the guide slots 15 and 15 are formed and the positions where the locking ribs 16a and 16b protrude are appropriately determined according to the thickness of the lift plate 2, the thickness of the sheet-like material to be stored, and the like.

On the other hand, the lift plate 2 inserted into the container body 1
In the position corresponding to the guide elongated holes 15, 15,
Guide projections 21, 21, 21, 21 project from the side walls. FIG. 4 is a perspective view of the lift plate 2 and shows two upper and lower guide projections 21, 21 protruding from the right side wall 22a, but the shapes of these guide projections 21, 21 are not limited to this example. Instead, only one protrusion may be used, and two upper and lower protrusions may be continuous projections having a vertically long section. Two thin plate-like hooking claws 23 are provided near the left and right sides of the guide projections 21 and 21 as centers.
a, 23b are protruded at substantially symmetrical positions in parallel with the vertical direction.

When the lift plate 2 is inserted into the container body 1, the guide projections 21, 21, 21, 21 of the lift plate 2 are inserted into the guide slots 14, 14 in the container body 1.
The lift plate 2 can move up and down within a range where the guide slots 15 are formed. In addition, in this example, in order to prevent the guide protrusions 21,21,21,21 of the lift plate 2 from dropping out of the elongated guide holes 15,15 of the container body 1, and to facilitate the operation, the lift plate 2 is After being inserted into the container body 1, operation buttons 24, 24 are fitted to the tips of the guide projections 21, 21, 21, 21, respectively.

The vertical position of the lift plate 2 inserted in the container body 1 is maintained in the container body 1 by the hooking claws 23a and 23b being hooked on the hooking ribs 16a and 16b, respectively.

The lift plate 2 has left and right side walls 22a, 22a.
Slit holes 25, 25 are formed on the inside where b is left thin. The slit holes 25, 25 of this example are the guide protrusions 21, 21, 2
It is formed in a flat, half-moon-like shape with the opening width of the center portion wider than both end portions, centering on the portion where the hooks 1, 21 and the hooking claws 23a, 23b are provided.

As described above, when the guide projections 21, 21, 21, 21 are pressed inward through the operation buttons 24, 24, the remaining side walls 22a, 22b are bent inward, so that the guide plate 2 Stop claws 2
The engagement between the hooks 3a, 23b and the retaining ribs 16a, 16b of the container body 1 is released. Since the side walls 22a and 22b of the lift plate 2 made of synthetic resin have elasticity like a leaf spring, when the pressing of the operation buttons 24 and 24 is stopped, the side walls 2a and 22b are stopped.
2a and 22b are restored to the original state, and the hook 23 of the guide plate 2 is
a and 23b re-engage with the locking ribs of the container body 1.

The lift plate 2 has support projections projecting from the side walls 22c and 22d on the side where the hooking claws are not formed. As shown in FIG. 4, the support projections 26, 26, 26, 26 of this example are
In the front and rear side walls 22c and 22d, two rails protrude vertically. These support projections 26, 26, 26, 2
6 is formed so as to abut the inner wall of the container body 1,
At the time of raising / lowering operation of the lift plate 2, the side wall of the lift plate 2
This contributes to reducing the friction between the inner walls 22c and 22d and the inner wall surface of the container body 1. In the packaging container of this embodiment, as shown in FIG. 3, two guide rails 17 are provided on the inner wall of the front cover 11 and the inner wall of the rear cover 12, respectively, and the guide rails 17 are supported outside the guide rails 17, 17. Since the projections 26 are formed so as to be in contact with each other, the lift plate 2 does not move in the left-right direction even during the ascent / descent operation, so that a more stable ascent / descent operation can be performed.

FIG. 5 is a partially enlarged view of the vicinity of the hinge in FIG. In the packaging container of this example, the container body 1
A leaf spring 4 made of silicon rubber as shown in FIG. 6 is used for a hinge portion that allows the rear cover 12 and the lid 3 to be opened and closed. As shown in FIG. 5, one end side insertion piece 41 of the leaf spring 4 is inserted and fixed to the gate-shaped fixing portion 32 near the rear end of the lid 3, while, as shown in FIG. The other end side insertion piece 42 of the spring 4 is inserted and fixed to a gate-shaped fixing portion 121 at the upper end of the rear cover 12. On the other hand, from the rearmost end of the lid 3, two rotation axes
The cover 3 is connected to the container body 1 (rear cover 12) by fitting the rotating shafts 33, 33 into bearing holes 122, 122 at the upper end of the rear cover 12, and the cover 3 Is opened and closed.

As shown in FIG. 5, a lock claw 31 is provided at the front end of the lid 3, and the lock claw 31 fits into the lock hole 18 at the front upper end of the front cover 11. Thereby, the lid 3 is maintained in the closed state.
Slit grooves 19, 19 are provided near the left and right of the lock hole 18, so that when the lower part of the lock hole 18 is pressed with a finger or the like, the slit groove 19, 19 is elastically deformed so as to bend toward the inside of the container body 1. Then, the engagement of the lock claws 31 is released, and the lid 3 is opened. At this time, the lid 3 is greatly opened upward to the vertical extent by the urging force of the leaf spring 4, so that the stored cotton or the like is exposed near the outlet 14, facilitating the removal.

FIG. 8 is a perspective view of an example in which the packaging container according to the present invention is applied as a pocket tissue storage container.
Pocket tissues that are frequently distributed free of charge at stations, financial institutions, and the like as advertising media often accumulate in homes without your knowledge and often cause organization and complications. In the packaging container according to the present invention, it is of course possible to store the thin pocket tissue packaged in the bag in an unopened state and to take out one by one as needed, such as when going out. When the slot 34 is opened in the lid 3, the opened pocket tissue is stored in the container, and the topmost tissue paper is inserted into the slot 34.
By simply exposing the box tissue from the box tissue, it can function similarly to a so-called box tissue.

[0026]

According to the present invention, when the remaining amount of the sheet-like material stored in the container body is reduced, the guide projection of the lift plate projecting from the side wall of the container body is reduced. The sheet-like material can be guided to the container upper surface outlet only by raising the lift plate while pressing. Further, since the lift plate side wall surface has an elastic structure like a leaf spring by interposing the slit hole, the vertical position of the lift plate can be fixed only by releasing the pressing on the guide projection. Therefore, the sheet-like objects exposed from the container body upper surface opening can be taken out one by one without fail.

Further, in the case where the support projection is provided on the side wall of the lift plate, the support protrusion comes into contact with the inner wall surface of the container body, and the side wall of the lift plate does not adhere to the inner wall surface of the container body. This can provide an advantage that smooth operation can be performed while maintaining the horizontal state even when the lift plate is moved up and down.

Further, since the number of components is reduced, the cost can be reduced.
