It relates to packaging boxes that can be flattened and discarded.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, there is a packaging box for accommodating various kinds of articles, which is formed by assembling paperboard or corrugated paperboard as shown in FIGS. 7 and 8, for example. That is, the packaging box (50) has a body portion (55) composed of four side plates (51, 52, 53, 54) arranged in a rectangular tube shape, and an upper opening of the body portion (55). A bottom formed by connecting the lid part (56) connected to the peripheral part and the bottom flaps (57, 58, 59, 60) connected to the bottom of each side plate (51, 52, 53, 54) to each other. It consists of a part (61). That is, the bottom portion (61) is formed by adhering the bottom flaps (57, 59) extending to the lower portions of the pair of side plates (51, 53) adjacent to each other to each other, and the other pair of bottom flaps (57, 59) attached to each other. It is formed by engaging and connecting with (58, 60). Further, in the packaging box (50), a partition plate (62) is arranged so that the vials and the like to be housed do not collide with each other, and the partition plate (62) is a side plate (51/52).・ 53 ・ 54) It is configured so that it can be assembled on the inner surface to assemble the packaging box by a simple operation.

[0003] The packaging box (50) is made of thick paper and sturdy to prevent the contents from falling out due to the bottom of the packaging box being handled and the box being broken during stacking. Has been formed.

[0004]

[Problems to be solved by the device]

 The packaging box (50) is bulky in the three-dimensional state at the time of storage when the packaging is discarded, such as when the packaging is used up and the packaging is discarded, so it must be broken into a flat state. Due to the need for protection, it is made tough and cannot be easily broken. In particular, in the packaging box with the intermediate partition shown in FIGS. 7 and 8, the intermediate partition plate (62) arranged in the packaging box (50) acts as a reinforcing material, so that there is a problem that it is more difficult to break.

In order to solve this, for example, as shown in FIG. 9, of the bottom flaps (57, 58) located in the lowermost layer, the unbonded parts (64, 64) are located closer to the tip side than the bonded parts (63, 63). ) Is provided, and the unbonded part (64) is picked up with a finger to peel off the bonded part (63), thereby pulling out the bottom and breaking the packaging box (50). However, this adhesive part (63) is adhered with sufficient strength so that the bottom part (61) does not fall out due to the weight of the contents, so if you try to peel off the adhesive part (63), There is a risk that the paper material itself of the flaps (57/58) will break in layers and some of the bottom flaps (57/58) will remain on the adhesive part (63), making it difficult to break the packaging box (50). There are many.

An object of the present invention is to solve the above problems and to provide a packaging box which can be surely broken into a flat state by a simple operation and which can maintain a high box strength during use. It

[0007]

[Means for Solving the Problems]

 In the present invention, in order to achieve the above object, the packaging box is configured as follows. That is, a body portion (19) composed of a plurality of side plates (1, 2, 3, 4) arranged in a rectangular tube shape, and a lid portion (continuously connected to the peripheral portion of the upper end opening of the body portion (19) ( 21) and a bottom portion (20) formed by connecting the bottom flaps (6) connected to the lower portions of the side plates (1, 2, 3, 4) to each other, and forming the side plates (1, 2, 3 ,. Between the both ends (16, 16) of the lower edge (15) of at least one side plate (A) of 4), an easy break line (17) connecting the both ends (16, 16) is provided. The whole or a part of the middle part of the easy break line (17) is projected upward so as to be inserted into the side plate (A), and is pushed between the easy break line (17) and the side plate lower edge (15). It is configured by forming a fracture (18).

As a method of connecting the bottom flaps (6) to each other, adhesion, engagement or the like can be mentioned. Moreover, the easily breakable line (17) can be formed by perforations or notches.

[0009]

[Action]

 Since the middle part of the easy-break line protrudes upward and enters the side plate, even if the weight of the contents is added to the bottom, the part of the easy-break line that entered the side plate is parallel to the side plate surface. It does not break easily because it only applies force. When the packaging box is broken, if the pushing portion is pressed from the direction intersecting the plate surface of the side plate, the easily breakable line is easily broken, and the side plate and the bottom portion above the pushing portion are separated.

Form the barrel (19) as shown. After three-dimensionalizing this body (19) into a rectangular parallelepiped, fold the folds (s1 to s4) and stack the bottom flaps (6) in order, and finally stack the bottom flaps extending from the front side plate (1). (6a) is adhered and fixed to the bottom flap (6b) extending from the rear side plate (2) via the gluing part (11), thereby forming the bottom part (20). After the tablets (T) packed in the press-through pack (P) are stored in the body (19), the lid (21) including the inner lids (7a and 7b) and the upper lid (8) is covered. Then, a sealing tape (14) is stuck over the breaking opening (13) for opening and the upper lid (8) for sealing.

As shown in FIG. 1, when the contents (9) are taken out and then the packaging box (C) is broken into a flat state, the crushing portion (18) formed on the lower portion of the rear side plate (2) is pressed. To do. As a result, the easily breakable line (17) is easily broken, and the bottom of the packaging box (C) is removed. As a result, since the upper and lower parts of the body portion (19) are open, they can easily be flattened by applying a force from the side, and can be folded compactly as shown in FIG. As a result, packaging boxes that are no longer needed can be easily discarded, and they can be collected without taking up space, making it easy to recycle box materials.

In the first embodiment, since the easy break line (17) is formed only between the lower end edge both ends (16, 16) of the rear side plate (2), the easy break line is small and the packaging is easy. Although the strength of the box can be maintained, if the strength of the packaging box is high, a breakable line may be provided between both ends of the lower edges of the side plates. Especially, when all the bottom flaps (6) are adhered to each other to form a strong bottom part (20), by providing an easy break line between the lower end edges of the three or all side plates, The bottom can be easily pulled out to break the packaging box (C). Further, although the case where the paperboard is used has been described in the first embodiment, it is needless to say that the present invention can be applied to the case where the paperboard is formed of corrugated cardboard or other materials depending on the contents to be accommodated and the required box strength.

FIG. 4 shows Embodiment 2 of the present invention and is a partially cutaway perspective view of the opened state. In the second embodiment, an inner partition plate (22) is arranged in the packaging box (C), and the inside of the box is partitioned so that the stored vials (V) do not collide with each other.

The easily breakable line (17) may be provided between both ends of the lower edge of the wide front / rear side plates (1, 2), but as in the third embodiment, the narrow left / right side If it is provided between the both ends (16, 16) of the lower edge (15) of the right side plate (3, 4), the breakable line (17) can be shortened, and the risk of the bottom falling off due to the weight of the contents is reduced. The strength of the packaging box (C) can be maintained high.

FIG. 6 is a perspective view showing a fourth embodiment. In this embodiment, a breakable line is provided between both ends (16, 16) of the lower edge (15) of the front side plate (1) which is one side plate (A). Therefore, not only the packaging box (C) is easily broken into a flat state, but also the upper and lower crushing parts (13, 18) can be opened to open the wrapping box. Therefore, when the packaging box (C) is opened, it is not necessary to change the packaging box (C) in order to align the vertical direction, and the opening operation can be performed very easily.

In each of Examples 1 to 4 described above, the case in which the body is a rectangular parallelepiped is described. However, the body may be formed by arranging the side plates in the shape of a rectangular tube, and may be a cube or another polygon. It goes without saying that the present invention can be applied even in the case of a tubular shape.

【effect】

 Since the present invention is constructed and operates as described above, it has the following effects. (A) The side plate and the bottom are easily separated by simply pressing the crushing part, and the bottom is removed. On the other hand, since the lid on the upper end of the body is open when the contents are taken out, the upper and lower ends of the body are open, and they can be easily folded by applying a lateral force. , The entire packaging box can be broken flat. Moreover, in the use state in which the contained items are accommodated, the packaging box is not easily broken at the easy break line, and the strength of the packaging box can be maintained high.

(B) In the case where bottom flaps extending from the lower end edges of the pair of side plates are attached to each other and an easily breakable line is provided between both end portions of the lower end edges of one of the both side plates. Since it is only necessary to form the breakable line only between both ends of the lower edge of the side plate, the paperboard for assembling the packaging box can be easily processed, and the breakable line formed on the packaging box is small. Since it is dull, the strength of the packaging box in use can be maintained.

(C) When the partition plate is provided inside the packaging box and the crushing portion is formed at a portion deviating from the position where the intermediate partition plate is provided, when the crushing portion is pressed, Since the partition plate does not get in the way and the crushing portion can be easily crushed, even if the packaging box is provided with the partition plate, the packaging box can be broken very easily.
