DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container for confectionery and the like.

[0002]

2. Description of the Related Art Conventionally, as a container for confectionery or the like, both ends are closed by a lid plate so as to be openable and closable.
There has been proposed a device in which an outlet is formed on any one of the peripheral walls of the surface, and confectionery or the like contained in a container can be taken out from the outlet one by one.

In such a container, a cover is slidably inserted into the container so as to cover the outer surface of the peripheral wall of the container so that confectionery and the like are not unintentionally removed from the outlet. In this case, the cover has an outlet formed on a peripheral wall corresponding to the peripheral wall on which the container outlet is formed.In general, the cover is located at a position where the container outlet is closed, and the cover is attached to the container. When the container is slid and the outlet of the cover is aligned with the outlet of the container, the confectionery or the like contained in the container is taken out.

[0004]

However, in the above-mentioned container, since the cover slidably fitted in the container slides easily with respect to the container, the outlet of the cover needs to be removed from the container. When adjusting to the exit, depending on the power
There is a disadvantage that the cover easily falls off from the container or goes too far with respect to the outlet of the container, and the positioning is complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to prevent a cover from unintentionally falling off by positioning a cover between an open position and a closed position for taking out confectionery or the like. It is intended to provide a packaging container which can be used.

[0006]

According to the present invention, the opening at both ends is closed by a cover plate so as to be openable and closable, and an outlet is formed on any one of four peripheral walls adjacent to the cover plate. And a cover having an outlet formed on a peripheral wall corresponding to the peripheral wall on which the container outlet is formed, the cover being slidably fitted over the outer peripheral surface of the peripheral wall of the container, the cover comprising: Usually, the container is located at a position where the outlet of the container is closed, and by sliding the cover, the outlet of the cover is matched with the outlet of the container, and the contents of the container are taken out of the container. A locking piece that is folded in contact with the outer surface of the one peripheral wall is provided, and a notch is formed in a peripheral wall of the cover corresponding to the one peripheral wall into which the locking piece of the container is folded, and the notch of the cover is formed. From the vertical dimension of the peripheral wall at the left and right edge corners Protruding portions protruding outward are formed,
When the cover outlet is in the closed position away from the container outlet, the left and right edges of the locking piece and the left and right one edges of the notch are locked, and the cover outlet is the container outlet. And the other left and right edges of the locking piece and the left and right other edges of the cutout portion are locked when in the open position that matches.

According to the present invention, when the cover is inserted into the container, the locking piece of the container is located in the notch of the cover. The cover can be slid in the range of the cutout portion until each edge is locked, and the cover can be prevented from coming out of the container unintentionally.

At this time, the position where the left and right edges of the cutout portion of the cover and the left and right edges of the locking piece of the container are locked is set to a closed position where the cover outlet and the container outlet are separated. In addition, the position where the left and right other edges of the cutout portion of the cover and the left and right other edges of the locking piece of the container are locked is set to an open position where the cover outlet and the container outlet match. Thereby, the cover can be slid only between the open position for taking out the contents stored in the container and the closed position.

In the present invention, if a slit having a fixed length is formed on the left and right sides of the peripheral wall on which the notch portion of the cover is formed with a connecting portion on an extension of the upper end edge of the notch portion, the notch of the cover may be formed. It is possible to reliably elastically deform the vicinity of the left and right edges of the portion in a state inclined inward along the slit, and to securely lock the left and right edges of the cutout portion and the left and right edges of the locking piece. Can be achieved.

In the present invention, if a bulging portion is formed at the edge of the lid plate on the side of the lid plate of the container on which the outlet of the cover is slid in the direction coinciding with the outlet of the container, When the cover is slid to the open position, the edge of the cover comes into contact with the bulge and generates a collision sound when it gets over it. You can figure out.

In the upper plate 12 and the front plate 13, rectangular openings 12x and 13x having predetermined horizontal dimensions and vertical dimensions are formed at their folds b at substantially central portions in the width direction.
Are formed so as to communicate with each other. The front plate 13 has an outlet 13y formed near the left edge thereof.
Further, the left lid plate 16, which is located on the side of the outlet 13 y formed in the front plate 13 and is connected to the upper surface plate 12, has an edge on the side in contact with the left edge of the front plate 13. A bulging portion 161 is provided so as to slightly protrude outward from the edge.

Next, the procedure for assembling the container 10 thus constructed will be described.

First, after the paperboard is punched in accordance with the developed view of FIG. 3, a transparent film 30 (FIG. 3) is formed on the back side peripheral edges of the openings 12x and 13x formed over the upper surface plate 12 and the front plate 13 through an adhesive. 1) and attach the opening 1
Seal 2x, 13x.

Thereafter, the top plate 12 is folded along the fold a with respect to the back plate 11, the front plate 13 is folded along the fold b with the top plate 12, and the bottom plate 14 is folded with the front plate 13 along the fold c. Fold each along. In addition, each flap 15 is mountain-folded along the fold d with respect to the back plate 11 and the front plate 13, and each cover plate 16 is mountain-folded along the fold e with respect to the top plate 12. Each folded piece 18 is mountain-folded on the plate 16 along the fold line g. Further, the attachment piece 17 is mountain-folded along the fold line f with respect to the bottom plate 14, and the locking piece 19 is mountain-folded along the fold line h.

Next, an adhesive is applied to the outer surface of the sticking piece 17 and the sticking piece 17 is stuck to the inner surface of the back plate 11 to form a quadrangular prism-shaped cylindrical body having both left and right end faces opened.
At this time, the locking piece 19 is folded along the outer surface of the bottom plate 14 (see FIG. 2). After that, the container 10 whose one end face is closed by the cover plate 16 is formed by inserting one folded piece 18 so that its outer surface is in contact with the inner surface of the bottom plate 14. In this state, after the confectionery or the like is stored in the container 10 through the other end face that is opened, the other folded piece 18 is similarly inserted so that the outer surface thereof is in contact with the inner surface of the bottom plate 14, so that the other lid plate 16
The other end face is closed by the
0 can be formed (see FIGS. 1 and 2).

In this case, whether or not a confectionery or the like is stored in the container 10 can be grasped through the transparent film 30 covering the openings 12x and 13x.

On the other hand, the cover 20 is assembled by punching out a plastic film according to the development shown in FIG. 4, folding it along the fold line, and attaching a predetermined portion.

In the developed view of FIG. 4, the cover 20 is provided with a top plate 22, a front plate 23, and a bottom plate at the lower edge of a rear plate 21 having an adhesive strip 25 connected to the upper edge via a fold s. 24 are sequentially provided via folds p, q, and r.

An outlet 23y is formed near the center of the front plate 23, and a rectangular cutout 24x opening at the lower end thereof is formed substantially at the center of the bottom plate 24. I have. Further, a protrusion 241 projecting outward from the lower edge is formed at a corner where the left and right edges and the lower edge of the notch 24x formed on the bottom plate 24 intersect. The vertical dimension from the tip of the protrusion 241 to the fold r is set slightly larger than the vertical dimension between the folds p and q, which is the vertical dimension of the upper surface plate 22. Also, the bottom plate 24
, A slit 24y of a fixed length is formed on the left and right sides of the notch portion 24x on the extension line of the upper end edge thereof in parallel with the fold r, leaving a slight connecting portion.

Here, the cover 20 has substantially the same lateral dimensions as the container 10, but the back plate 1 of the container 10
1, top plate 22, front plate 23, bottom plate 24 of cover 20 so as to cover top plate 12, front plate 13 and bottom plate 14 and slide along their outer surfaces.
Is formed to be slightly larger than the vertical dimensions of the top plate 12, the front plate 13, and the bottom plate 14 of the container 10.

The lateral dimension of the front plate 23 of the cover 20 is set substantially equal to the lateral dimension of the front plate 13 of the container 10. The rear plate 21 is formed to be shorter and shorter than the horizontal dimension of the front plate 23, and has a left end edge and the upper plate 2
2 and a notch formed at the upper left corner of the bottom plate 24 are continuous. For this reason, the cover 20 is
When inserted into the container 10, a part of the back plate 11, the top plate 12, and the bottom plate 14 of the container 10 can be exposed.
Exposed back plate 11, top plate 12 and bottom plate 1
4 can be grasped with a fingertip.

Next, the procedure for assembling the cover 20 thus configured will be described.

First, after a plastic film is punched according to the development shown in FIG.
, Along the fold r, the adhesive is applied to the inner surface of the upper half of the adhesive piece 25, and the back plate 21 is mountain-folded along the fold p with respect to the upper surface plate 22. 25
On the outer surface of the bottom plate 24. Next, the cover 20 can be formed by mountain-folding the back plate 21 and the front plate 23 so as to rise along the folds s and q, respectively (see FIGS. 1 and 2).

At this time, the tip of the protruding portion 241 of the bottom plate 24 has a length protruding from the vertical dimension of the top plate 22 and is equal to the length of the sticking piece 2.
5 and is in contact with the inner surface of the back plate 21.
Here, since the slit 24y is formed in the bottom plate 24, the vicinity of the left and right edges of the cutout portion 24x of the bottom plate 24 is surely elastically deformed into an inclined state away from the inner surface of the sticking piece 25 ( (See FIG. 2).

Here, the position where the outlet 23y of the cover 20 and the notch 24x are formed is determined by the position where the outlet 13y of the container 10 and the locking piece 19 are formed. That is, when the cover 20 is inserted into the container 10 and both edges of the cover 20 are substantially aligned with both end surfaces of the container 10, as shown in FIG.
The outlet 23y of the cover 20 is located at a position away from the outlet 13y of the container 10 to the right, and the notch 24x
And the left edge of the locking piece 19 are locked. On the other hand, from this state, the cover 20 is slid to the left with respect to the container
When y is made to coincide with the outlet 13y of the container 10, as shown in FIG. 6, the positioning is such that the right edge of the notch 24x and the right edge of the locking piece 19 are locked.

Therefore, in order to form the packaging container 1 by the container 10 and the cover 20, the cover 2 corresponding to the two adjacent surfaces of the container 10 and the two adjacent surfaces of the container 10 is formed.
0 are directed to the same side, for example, as shown in FIG. 2, the back plate 11 of the container 10 and the back plate 2 of the cover 20.
1 is turned to the near side, the bottom plate 14 of the container 10 and the bottom plate 24 of the cover 20 are turned to the upper surface, and the left open end of the cover 20 is opposed to the right cover plate 16 of the container 10. Then, the cover 20 is inserted into the container 10. At this time, when the left edge of the bottom plate 24 of the cover 20 interferes with the right edge of the locking piece 19 folded in contact with the outer surface of the bottom plate 14 of the container 10, the locking piece 19 is slightly lowered. It may be pressed to prevent interference with the cover 20. When the left and right edges of the cover 20 and the left and right end surfaces of the container 10 substantially match, the left edge of the locking piece 19 is locked to the left edge of the notch 24x formed in the bottom plate 24 of the cover 20, Further sliding is prevented. In this state, the outlet 23y of the cover 20
Is located away from the outlet 13y of the container 10, and the outlet 13y of the container 10 is closed by the cover 20 (see FIG. 5).

On the other hand, when the consumer wants to take out the confectionery or the like contained in the container 10, the cover 20 is placed on the container 10
, The outlet 23y of the cover 20 may be made to coincide with the outlet 13y of the container 10. In this state, the right edge of the locking piece 19 is locked to the right edge of the notch 24x formed in the bottom plate 24 of the cover 20, and further sliding is prevented.

In this case, the left cover plate 16 of the container 10
A bulge 161 protruding outward from an edge facing the front plate 13
Is formed, when the cover 20 is slid to the left, the left end edge of the front plate 23 abuts against the bulging portion 161, and the bulging portion 161 is elastically deformed when going over the bulging portion 161. A crisp collision sound is generated by returning.
For this reason, the fact that the cover 20 is slid in the direction of the takeout position of the confectionery or the like can be grasped by the collision sound generated when the front plate 23 and the bulging portion 161 of the cover plate 16 come into contact with each other and get over.

As described above, the left and right edges of the notch 24x formed in the bottom plate 24 of the cover 20
Notches 2 that are not locked to the left and right edges of the locking piece 19 folded in contact with the outer surface of the bottom plate 14 of FIG.
It is slidable only within the range of 4x, and it is possible to reliably prevent the cover 20 from unintentionally falling out of the container 10 and to reliably position the cover 20 at an open position for taking out confectionery and the like. it can.

In the above-described embodiment, the case where the locking piece 19 is connected to the back plate 12 and the locking piece 19 is folded in contact with the outer surface of the bottom plate 14 when the container 10 is assembled is exemplified. However, the locking piece can be folded so as to be in contact with an arbitrary face plate such as the top plate 12, the front plate 13, or the back plate 11 other than the bottom plate 14, and in this case, the locking piece is A notch may be formed in the corresponding face plate of the cover 20. For example, in the developed views of FIGS. 3 and 4, the locking pieces 19 </ b> R are folded along the respective folds in the opposite manner as described above, so that the locking pieces 19 </ b> R are connected to the upper surface plate 12 </ b> R (FIG. Can be folded in contact with the bottom plate 14) of the cover 20, and a notch 22x can be formed in the top plate 22R (the bottom plate 24 in FIG. 4) of the cover 20 corresponding to the top plate 12R of the container 10. These locking pieces 19R and notch portions 22x can be locked on the upper surface.

In this case, if the paperboard has a front and a back, FIG.
The design may be changed so that the development view shown in FIG. In any case, by changing the developed view, the locking piece can be provided in contact with an arbitrary face plate of the container 10, and the cover 1 corresponding to the face plate provided with the locking piece can be provided.
A notch can be formed in the 0 face plate.

However, the locking piece and the notch are connected to the outlet 1
A face plate on which 3y and 23y are formed (in the embodiment,
In the case of locking by the front plates 13, 23), it is necessary to position the cover 20 within the sliding range of the cover 20 so as not to interfere with the outlet.

The outlet 13y of the container 10 is connected to the front plate 1
Although the case where it is formed near the left edge of 3 has been described, the outlet may be formed in an arbitrary face plate, and the formation position is not limited to the vicinity of the left edge, but may be formed in any position.

Further, the contents contained in the container include:
It is not limited to confectionery.

[0040]

As described above, according to the present invention, the cover is provided only within the range of the notch which is not locked by the right and left edges of the notch of the cover and the right and left edges of the locking piece of the container. Since the cover can be slid with respect to the container, it is possible to reliably prevent the cover from unintentionally falling out of the container, and to reliably position the cover at an open position where the confectionery or the like is taken out.
