Description

[Detailed Description of the Invention] The present invention relates to a cardboard box for collectively packaging a plurality of products using cup-shaped or bottle-shaped containers.

Various types of boxes are used to collectively package liquid or semi-solid drinks such as pudding, jelly, and yogurt in cup-shaped or bottle-shaped containers. There is. The one shown in Fig. 1 is one of the typical examples, and includes a top plate 2 having a container insertion hole 1 for supporting containers for products to be collectively packaged on its side, and a top plate 2 for supporting the bottom of the containers. It has a flat hexahedral shape, consisting of a bottom plate 3 and side plates 4. FIG. 2 shows a state in which a container 5 is inserted into the container insertion hole 1 of this box. In FIG. 1, reference numerals 6 and 7 indicate engagement pieces and their engagement holes that facilitate accurate stacking of boxes to prevent them from collapsing.

A collective packaging box like the one shown in Figure 1 has a simple appearance, but in order to accommodate a large number of products and ensure the necessary strength or shape stability to withstand transportation and other handling, it is necessary to Considerable effort is required in the structural design. To explain this with respect to the box shown in Fig. 1, conventionally, for example, a corrugated paper piece for forming a top plate as shown in Fig. 3A and a corrugated paper piece for forming a bottom plate as shown in Fig. 3B were folded and folded in a complicated manner. By doing this, we obtained a box with the necessary strength. However, such conventional boxes have the disadvantage that each box must be assembled manually. Furthermore, since a large amount of corrugated paper was required, the shape stability was poor and the dimensional accuracy was poor, so the engagement between the engagement piece 6 and the engagement hole 7 was also uncertain. Furthermore, if products are stacked together for group packaging, the tops of the products exposed on the top plate will support the bottom of the box above, which can result in the products getting dirty or being crushed. There were flaws.

The present invention provides a collective packaging box that does not have the above-mentioned drawbacks, that is, a hexahedral box such as the example shown in FIG. It consists of a rectangular part between the top plate forming part and the bottom plate forming part on the paper piece, and the other side plates protrude from each of the four sides of the bottom plate forming part other than the side connecting with the side plate forming rectangular part. The side plate forming part is bonded to the side plate forming part similarly provided around the bottom plate forming part in an overlapping state over the entire surface, and extends from the boundary part between the top plate forming part and the side plate forming part to the top plate forming part. An engagement piece formed by cutting a part of the top plate forming part into a tongue shape and standing upright, and an engagement piece formed by cutting out a side plate from the bottom plate side below the engagement piece forming part. The engaging piece has an engaging hole, and only a part of the distal end thereof is wide enough to fit into the engaging hole, and the remaining base side is wide enough to not fit into the engaging hole. and the height of the wide part on the base side is
To provide a collective packaging box characterized by being larger in height than the part of the packaged products protruding from the top plate.

The present invention will be described below with reference to specific examples.

FIG. 4 is a perspective view showing one embodiment of the present invention, in which 8 is a top plate, 9 is a bottom plate, 10 is a side plate, 11 is a container insertion hole, and 12 and 13 are the collective packaging of FIG. 1. This is an engagement piece and its engagement hole that have the same function as the one in the box. However, unlike the one in FIG. 1, the entire engagement piece 12 is connected to the engagement hole 1.
It is not designed to fit into 3. That is,
As shown in FIG. 6, the engagement piece 12 of the lower box B ₁ has only a half portion 12a on the tip side that is wide enough to fit into the engagement hole 13 of the upper box B ₂ ; The base side portion 12b is wider than the width of the engagement hole 13 and does not fit into the engagement hole 13. For this reason,
The shoulder portion 12c of the engaging piece 12 comes into contact with the side plate bottom 10a of the upper box _B2 , thereby supporting the upper box _B2 . As a result, the bottom plate 9 of the upper box B ₂ and the lower box B ₁
A gap G is formed between the top plate 8 and the top plate 8. This =
By making the vertical size D of the gap G slightly larger than the height h of the part of the product P protruding from the top plate 8, the product P can be placed in a state where it supports the box B ₂ above. can be prevented. Further, FIG. 5 is a developed view of the collective packaging box shown in FIG. 4. In the figure, a portion 14 surrounded by broken lines F ₁ to _{F 4} shown in broken lines is a top plate forming portion, and a portion 15 surrounded by broken lines F ₅ to _{F 8} is a bottom plate forming portion. The side plate forming portions are located between the fold lines F ₁ and F ₅ 16 and outside the other fold lines 17 to 22, and all have substantially the same shape except for the difference in the shape of the perforation. 23 is a reinforcing tongue piece.

To make the box shown in Fig. 4 from a piece of paper like that shown in Fig. 5, fold all the fold lines upwards on the paper, and form the side plate forming parts 18 and 21, 17 and 22, and 19. 20 are stacked one on top of the other (with the top plate forming part on the outside) and adhered using an adhesive such as hot melt adhesive. In addition, tongue piece 23
is attached to the inside of the side panel. Due to the presence of the notch 24 and the fact that the fold lines F ₁ and F ₃ are discontinuous as shown, the engagement piece 21 is automatically formed when the above assembly operation is performed.

Although ventilation holes 25 are provided in some of the side plates of the box in the above example, similar ventilation holes may be provided in other side plates and the bottom plate as required.

Based on the above structure, the collective packaging box according to the present invention has many features as listed below.
This is extremely effective for improving collective packaging technology.

Because the three side plates have a completely bonded double structure with side plate forming parts of the same shape overlapping each other,
It has good dimensional accuracy and is resistant to compression, making it difficult to deform.

An engaging piece is formed by cutting a part of the top plate forming part into a tongue shape and standing upright by a cut extending from the boundary part between the top plate forming part and the side plate forming part to the top plate forming part, and the above-mentioned engagement Since the engaging piece is formed by cutting out the side plate from the bottom plate below the piece forming part, there is no risk that the engaging piece will separate from the top plate. Since the side wall is formed deeply into the thick side wall with overlapping paper pieces, the engaging piece and the engaging hole can easily and reliably engage.

As a result of the above, there is no fear that a package using the collective packaging box of the present invention will tilt or collapse even if a large number of packages are stacked. Also, thin, inexpensive corrugated paper can be used to provide the desired strength.

Since it can be made from a single piece of paper with simple bending and gluing, the entire process from the base paper to the box can be mechanized, making it possible to manufacture it efficiently and inexpensively.

When stacked, a gap is formed between the bottom plate of the top box and the top plate of the bottom box due to the action of the engagement piece supporting the top box with its wide part, so that the bottom plate of the top box It is possible to prevent the product from being contaminated or crushed by contacting and pressing the product.
