However, this invention is not limited to a packaging container for gum. The contents may be confectionery other than gum, such as chocolate, chocolate confectionery, candy, gummi, tablet confectionery, biscuits, snacks, rice crackers, Japanese confectionery, and the like. Moreover, although the chewing gum of a gum is demonstrated as garbage, garbage is not limited to this. For example, the packaging material (individual packaging material) of the contents or an unnecessary material such as a packaging material that wraps the packaging container may be used.

FIG. 1A is a perspective view of a packaging container 1 according to an embodiment of the present invention as viewed from one end side (front side), and is a perspective view of a state in which an inner container 4 is fitted into an outer sleeve 3. . FIG. 1B is a perspective view of the packaging container 1 as viewed from one end side (front side), and is a perspective view in a state where one end side (front side) of the inner container 4 is pulled out from the outer sleeve 3. is there.

As shown in FIG. 1 (A) and FIG. 1 (B), the packaging container 1 according to this embodiment has a cylindrical shape and is fitted to the outer sleeve 3 so that both ends are open and the outer sleeve 3 can be pulled out. And an inner container 4. In a state where the inner container 4 is fitted into the outer sleeve 3, a locking claw 5 formed on the front edge of the outer sleeve 3 is formed on the upper surface on the front side of the inner container 4 (on the rear edge of the folded portion 6). The inner container 4 is held in the outer sleeve 3 (see FIG. 1A).

On the other hand, in the state where the inner container 4 is pulled forward from the outer sleeve 3, as shown in FIG. 1B, the contents 10 accommodated in the first accommodation chamber 9 through the opened upper surface 8 of the inner container 4. (In this embodiment, the contents 10 are individually packed granular gums) can be exposed. Then, the contents 10 can be taken out from the first storage chamber 9.

FIG. 2 (A) is a perspective view of the packaging container 1 as viewed from the other end side (rear side), and FIG. 2 (B) is an illustrative view of a longitudinal section at the center of the packaging container 1.

Referring to FIG. 2 (A), a one-way inlet 12 is provided on the other end side (rear side) of the packaging container 1. The one-way inlet 12 includes an opening 14 formed in the rear end surface (rear wall 44) of the inner container 4 and a pair of flap pieces 15. The one-way inlet 12 is an inlet for inserting an object from the other end side (rear side) of the inner container 4 into the accommodation space in the inner container 4 and has a structure in which the inserted object does not return. .

One of the characteristics of the packaging container 1 according to this embodiment is that the storage space 16 in the inner container 4 is formed by a flexible partition film 17 provided in the inner container 4 with reference to FIG. That is, the first storage chamber 9 and the second storage chamber 18 are partitioned. In the initial state, the partition film 17 is in a state where the entire lower surface thereof is in contact with the bottom surface 19 of the inner container 4, and the first storage chamber 9 is interposed between the upper surface of the partition film 17 and the outer sleeve 3. Is in a partitioned state. In the initial state, the second storage chamber 18 does not have a substantial storage space. And the content (individual packaging granule gum) 10 which is a content is accommodated in the 1st storage chamber 9. FIG.

For this reason, as shown in FIG. 1B, when the inner container 4 is pulled out from the outer sleeve 3, a first storage chamber 9 occupying the entire storage space of the inner container 4 appears and is stored in the first storage chamber 9. The content 10 made can be taken out.

The taken-out contents 10 are eaten and the chewing gum casket is wrapped in individual wrapping paper, for example, and can be inserted into the inner container 4 from the one-way inlet 12 as the chewing scum 20. The bite residue 20 inserted from the one-way inlet 12 is accommodated between the partition film 17 and the bottom surface 19 of the inner container 4. That is, the rear end portion 171 of the partition film 17 is bonded to the folded flap 45 provided continuously with the upper edge of the rear wall 44 of the inner container 4. For this reason, the bite residue 20 inserted into the inner container 4 from the opening 14 of the one-way inlet 12 lifts the flexible partition film 17 and widens the space between the lower surface of the partition film 17 and the bottom surface 19 of the inner container 4. A storage space is created and inserted into the second storage chamber 18 partitioned there.

Thus, the storage space 16 of the inner container 4 is partitioned into the first storage chamber 9 and the second storage chamber 18 by the partition film 17. Therefore, depending on the amount of the contents 10 stored in the first storage chamber 9 and the insertion amount of the bite residue 20 etc. inserted into the second storage chamber 18, the partition film 17 is attached to the first storage chamber 9. The first storage chamber 9 and the second storage chamber 18 are reliably partitioned while freely changing the volume and the volume of the second storage chamber 18. Therefore, the items contained in the two storage chambers are not in direct contact with each other.

FIG. 3 is a development view of the packaging container 1, FIG. 3A is a form view (development view) of a blank constituting the outer sleeve 3, and FIG. 3B is a form view of a blank constituting the inner container 4. FIG.

The blank 30 of the outer sleeve 3 includes an upper wall 31, left and

right side walls

32 and 33 that are connected to the left and right sides of the upper wall 31, a bottom wall 34 that is connected to the right side wall 33 and bent, and a left side wall. 32 and has a glue margin 35 for joining the left side wall 32 and the bottom wall 34. Each component part included in the blank 30 is bent along the fold line 36 into a cylindrical shape, and the bottom wall 34 and the adhesive allowance 35 are joined.

A concave notch 37 is formed at one end edge (front side) of the upper wall 31, and a locking claw 5 is formed so as to protrude into the concave notch 37. A recessed portion 37 is also formed on the front side of the bottom wall 34 and the adhesive margin 35. The recessed portion 37 is formed so that the front side of the inner container 4 can be easily pulled out from the outer sleeve 3.

Next, the blank 40 of the inner container 4 will be described with reference to FIG. The blank 40 includes a bottom wall 41, left and

right side walls

42 and 43 that are connected to the left and right side edges of the bottom wall 41 and bent, and a rear wall 44 and a rear wall that are connected to the rear edge of the bottom wall 41 and bent. 44, a folded flap 45 connected to the front end of 44 and bent, a pair of flap pieces 15 connected to the rear end edges of the left and

right side walls

42 and 43, and a front end edge of the bottom wall 41. A front wall 49 including the outer front wall 46, the folded portion 6, the inner front wall 47, and the fixed piece 48, and a pair of flap pieces 51 that are connected to the front end edges of the left and

right side walls

Further, the rear wall 44 is formed with an opening 14 for forming a one-way entrance at the center thereof. In this embodiment, the opening 14 is configured to open across the rear edge of the bottom wall 41.

In this embodiment, the opening 14 is described as being formed in the blank 40 from the beginning. However, a lid connected by a perforation is provided at the position of the opening 14, and this lid is later It is good also as a structure which an opening produces by tearing off (removing).

Further, an insertion notch 7 for inserting the locking claw 5 is formed at the boundary between the folded portion 6 and the inner front wall 47.

The blank 40 is folded along the fold line 53 and assembled into a boat-shaped inner container 4 having an open upper surface.

FIG. 4 is a development view for explaining the relationship between the blank 40 constituting the inner container 4 and the partition film 17 provided in the inner container 4.

4, the region (form) colored in gray is a development view of the partition film 17. Moreover, the hatching area | region given to the outline part in the partition film 17 has shown the adhesion | attachment area | region of the partition film 17 and the blank 40. FIG.

Specifically, the partition film 17 is composed of a resin film such as a flexible transparent film, a translucent film, or an opaque film having an outer edge shape corresponding to the shape of the blank 40, that is, an outer edge shape substantially equal to the blank 40. Yes. And the

edge parts

172 and 173 of the partition film 17 corresponding to the upper edge part (the upper edge part when each wall rises) of the left side wall 42 and the right side wall 43 of the blank 40 are the left side wall 42 of the blank 40 and The right side wall 43 is bonded. The rear end 171 of the partition film 17 corresponding to the leading end of the folded flap 45 of the blank 40 is bonded to the folded flap 45. Furthermore, the edge near the front edge of the bottom wall 41 of the blank 40 and the front edge 174 of the partition film 17 corresponding to the edge near the front edge of the left and

right side walls

42 and 43 are connected to the bottom wall 41 of the blank 40 and the left and right sides. The side edges 42 and 43 are bonded to the front end edges. A feature of this embodiment is that the partition film 17 and the blank 40 are not bonded to each other at the peripheral edge portion of the rear wall 44 in which the opening 14 is formed. That is, the blank 40 and the partition film 17 are not bonded at the

regions

175 and 176.

Thereby, when inserting a thing into the 2nd storage chamber 18 partitioned off by the bottom wall 41 and the partition film 17 from the opening 14, the space for the partition film 17 surrounding the opening 14 to change flexibly can be secured, The second storage chamber 18 can be expanded from the opening 14.

In other words, in the vicinity of the opening 14, the edge of the partition film 17 is not bonded to the inner wall of the inner container, and the partition film 17 can be freely deformed. Thereby, the 2nd storage chamber 18 can be expanded toward the front from the opening 14. FIG.

FIG. 5 is a perspective view illustrating a rear portion of the inner container 4 in a state where the blank 40 is assembled after the partition film 17 is overlaid and bonded to the blank 40 shown in FIG.

That is, in the initial state, as shown in FIG. 6 (A), in the initial state, the first storage chamber 9 defined by the upper surface of the partition film 17 and the outer sleeve 3 occupies almost the entire storage space 16. . However, by inserting an object from the opening 14, the partition film 17 is flexibly displaced upward by the inserted object, and an accommodation space is generated between the lower surface of the partition film 17 and the bottom surface 19 of the inner container 4. The storage chamber 18 is partitioned, and the second storage chamber 18 can gradually expand its volume to the front of the inner container 4.

In addition, when the blank 40 is initially assembled, the pair of flap pieces 15 are located inside the first storage chamber 9, but the partition film 17 can be flexibly displaced. It can be located outside the storage chamber 9. As a result, the one-way inlet 12 can be formed from the opening 14 and the pair of flap pieces 15, and the inserted object can be prevented from returning.

7A and 7B are perspective views of the rear side of the packaging container 1, and the flap piece 15 is pushed and rotated by pushing the bite residue 20 into the one-way inlet 12 from the outside. . Thereby, a gap through which the bite residue 20 can be passed is formed in the opening 14, and the partition film 17 is bent, and the bite residue 20 enters the inside while being pushed.

FIG. 8A is a cross-sectional view of the rear end side of the packaging container 1 as viewed from above, and shows a state in which the bite residue 20 is passing through the one-way inlet 12, and FIG. FIG. 8C is a cross-sectional view of the rear end side of the packaging container 1 as viewed from the left-right direction. FIG. 8C is a cross-sectional view of the rear end side of the packaging container 1 as viewed from above. The state after passing through is shown.

8A and 8B, the pair of flap pieces 15 are bent from the left and

right side walls

32 and 33 of the inner container 4 and are continuously provided. Further, the inner container 4 has a folded flap 45 folded from the rear wall 44. The folded-back flap 45 comes into contact with the upper end of the flap piece 15 when the pair of flap pieces 15 are opened. The folding flap 45 acts to suppress the flap piece 15 from opening.

Referring to FIGS. 8A and 8C, the pair of flap pieces 15 are in a closed state in which the movable ends are close to each other (the state shown in FIG. 8C) and the movable ends are moved away from each other. It can be displaced between the open state (the state shown in FIG. 8A). In the open state, the flap piece 15 is configured to return autonomously toward the closed state. As a result, after the bite residue 20 passes through the gap between the pair of flap pieces 15, the flap piece 15 rotates in the closing direction. Therefore, the inserted bite residue 20 is prevented from returning backward.

Further, when the bite residue 20 is inserted from the one-way inlet 12, the bite residue 20 deforms the partition film 17 to expand the second storage chamber 18 between the lower surface of the partition film 17 and the bottom surface 19 of the inner container 4. However, the bite residue 20 is accommodated in the second accommodating chamber 18.

FIG. 9 is a development view showing another outer edge form of the partition film 17.

The leading end side of the partition film 17 does not extend to the bottom wall 41 of the blank 40 constituting the inner container 4 and the leading end portions of the left and

right side walls

42 and 43, and is slightly from the leading edge of the bottom wall 41 and the left and

right side walls

42 and 43. In the position where it fell back, it is set as the structure by which the inner surface of the blank 40 and the front-end edge of the partition film 17 were adhere | attached. In this case, the volume of the second accommodation space 18 defined between the partition film 17 and the bottom wall 41 is reduced, but there is no problem.

FIG. 10 is a view for explaining the action of the locking claw 5 and the notch 7 in the fitted state and the drawn-out state between the outer sleeve 3 and the inner container 4 fitted in the outer sleeve 3 so as to be able to be drawn out. .

As shown in FIG. 10A, in a state where the inner container 4 is fitted to the outer sleeve 3, the locking claw 5 of the outer sleeve 3 is inserted into the notch 7 of the inner container 4 (this locking claw 5 Is inserted by the bending resilience of the locking claw 5.) The inner container 4 is locked to the outer sleeve 3 at a predetermined fitting position.

On the other hand, holding the tip of the inner container 4 with a finger and pulling the inner container 4 forward from the outer sleeve 3, the engagement between the locking claw 5 and the notch 7 is released, and the inner container 4 is removed from the outer sleeve 3. It can be pulled out forward (FIG. 10B). Then, the inner container 4 is pushed back to the outer sleeve 3, and when the inner container 4 reaches a predetermined position with respect to the outer sleeve 3, the locking claw 5 and the notch 7 are engaged, and the state shown in FIG. Become.

If the inner container 4 is further pushed into the outer sleeve 3 from this state, the tip of the outer sleeve and the tip of the inner container 4 coincide with each other. In this case, the relationship between the locking claw 5 and the insertion cut 7 is obtained. Will be in the state shown in FIG. When the rear side of the inner container 4 is pushed from this state and the inner container 4 is slightly pulled out, the state returns to the state shown in FIG.

Note that the engagement structure formed by the locking claws 5 and the notches 7 shown in FIG. 10 is not essential in the present invention. For example, the front wall 49 is a single piece whose vertical direction extends in the vertical direction. It may consist of a plate.

FIG. 11 (A) is a perspective view showing a state in which the one-way entrance portion of the packaging container 60 according to another embodiment of the present invention is opened. FIG. 11B is a development view of the packaging container 60. 12A and 12B are longitudinal sectional views of the packaging container 60 and are schematic longitudinal sectional views for explaining the function of the partition film 68 in the packaging container 60. FIG.

The configuration and function of the packaging container 60 will be described with reference to FIGS.

The packaging container 60 has a rectangular parallelepiped box shape, for example, a paper box formed by assembling one blank. On one end face side (the lower side in the figure) of the packaging container 60, a takeout port 62 for taking out the contents stored in the packaging container 60 is provided. The take-out port 62 is closed by a lid 63, and when the lid 63 is opened, the take-out port 62 appears.

A one-way inlet 64 is formed on the other end surface side (upper side in the drawing) of the packaging container 60. The one-way inlet 64 includes an opening 66 formed in the lid 65 and a pair of flaps 67. When an object is put into the container through the opening 66 in a state where the lid 65 is closed, the pair of flaps 67 are spread and the object enters inside. And since a pair of flap 67 returns, the thing which entered inside becomes a one-way entrance from which it does not return.

In the packaging container 60, a flexible resin-made partition film 68 for partitioning the internal storage space into a first storage chamber and a second storage chamber is provided. The partition film 68 has a shape that is almost the same as the outer shape of the blank including the bottom wall 71, the left and

right side walls

72 and 73, the lid 65, and the flap 74 constituting the packaging container 60, or a shape having a margin slightly larger than that. Yes. And the front-end | tip part of the flap 74 and the front-end | tip part of the partition film 68 are adhere | attached, and the upper edge part of the left-

right side walls

72 and 73, the lower end part of the left-and-right side wall, the lower end part of the bottom wall 71, and the lower end part of the partition film 68 And are adhered. Here, the point is that the both side edges of the lid 65 and the upper ends of the left and

right side walls

72 and 73 are not bonded to the partition film 68. Thereby, when putting an object from the opening 66, the partition film 68 near the one-way entrance 64 is flexibly deformed, and a second accommodation space can be formed between the partition film 68 and the bottom wall 71. is there.

That is, as shown in FIG. 12A, in the initial state, the partition film 68 is positioned on the bottom wall 71 side, and the first storage chamber 75 is defined in the packaging container 60.

On the other hand, when an object is put in from the one-way inlet 64, the partition film 68 moves and the second storage chamber 76 is partitioned between the partition film 68 and the bottom wall 71. Therefore, the first storage chamber Reference numeral 75 denotes a configuration in which the second storage chamber 76 separated by the partition film 68 expands.

When the packaging container 60 is assembled, the pair of flaps 67 are located inside the first storage chamber 75. However, since the partition film 68 can be flexibly deformed, the pair of flaps 67 are accommodated in the first storage chamber. It can be located outside the chamber 75. Thus, the one-way inlet 64 can be formed from the opening 66 and the pair of flaps 67, and the inserted object can be prevented from returning.

Thus, also in this embodiment, by using the flexible partition film 68, it is possible to reliably partition the accommodation space of the packaging container 60 into the first accommodation space 75 and the second accommodation space 76. it can.

In addition, in the packaging container 60 shown in FIGS. 11 and 12, the form of the pair of flaps 67 is not limited to the symmetrical flaps, but as shown in FIGS. 13 (A), 13 (B), and 13 (C). Alternatively, the flap 67 may be a pair of asymmetrical left and right.

The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the claims.

For example, although the

openings

14 and 66 have been described as being cut out from the beginning in the above embodiment, the

openings

14 and 66 may each have a lid initially connected by a perforation or the like. For example, in the embodiment shown in FIG. 3 and the like, in the blank 40, the opening 14 may be provided with a lid connected by a perforation, and the lid may be connected to the rear wall 44. In this case, the person who purchased the product tears the lid connected by the perforation (or pushes it into the container and removes it) to form the opening 14 (opening 66 in the embodiment of FIG. 11) and use it. be able to.
