Description

[Detailed Description of the Invention] The present invention relates to an improvement of 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. However, the one shown in Figure 1 is one of the typical ones, and it has a container insertion hole 1 for supporting containers of products to be collectively packaged on their sides.
a top plate 2 having a top plate 2, a bottom plate 3 supporting the bottom of the container,
It has a flat hexahedral shape and includes a side plate 4 and a side plate 4. After the container 5 is inserted into the container insertion hole 1 (the state shown in FIG. 2), the box is transported, stored, exhibited for sale, etc., and then discarded.
Therefore, this type of box does not have a lid that is always present in other ordinary boxes, and all sides of both the top and bottom plates are fixed to the side panels.

It has been pointed out that the above-mentioned type of collective packaging box has a problem in that it is difficult to disassemble it after use due to its special structure. In other words, when disposing of a cardboard box, it must be dismantled to the minimum extent necessary to avoid bulk, flattened, and bundled together in the same way as a normal cardboard box. Because it has a six-sided fixed structure, and because both the top and bottom plates are made from a single piece of paper, there is no suitable place to start disassembly.
It cannot be easily disassembled without using a knife or scissors.

The present invention is a collective packaging box that can be easily disassembled without using tools such as a knife, in other words, the top plate, side plates and bottom plate are made of a single piece of paper, and the top plate part is not removed. In corrugated paper collective packaging boxes that are disposed of after being used in the shape of a facepiece, on the bottom plate, if the bottom plate is square, along two diagonals, or if the bottom plate is rectangular, the short side is the bottom side. Perforations or equivalent discontinuous cuts to facilitate cutting of the bottom plate along the sides sandwiching the vertices of the two right-angled isosceles triangles and the straight line connecting the vertices of the two triangles. The present invention provides a box for collective packaging, which is characterized by having a cutting auxiliary line consisting of the following, and furthermore, the corner portion between the side plates can be broken by hand.

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

FIG. 3 is a developed view of an embodiment of the present invention whose appearance as a box is similar to that _{of FIG} . The part 6 is the top plate forming part, and the fold line F ₅ to _{F 8}
The portion 7 surrounded by is the bottom plate forming portion. The other parts are used for overlapping and gluing to form side plates.

The bottom plate forming portion 7 has discontinuous cuts 8 to 12. As is clear from the figure, cuts 8 and 9
is along the two sides sandwiching the vertices of a right-angled isosceles triangle whose base is the short side/broken line _F6 of the rectangular bottom plate forming part 7, and the cuts 10 and 11 are a right-angled isosceles triangle whose base is the broken line _F8 . along the two sides that sandwich the vertices of. These four cuts are cuts (so-called zippers) in which the tear easily propagates only in the direction of the corner portion of the bottom plate forming portion 7. Also, the cut 12 connecting the vertices of the two isosceles triangles is
This is a so-called perforation in the shape of a broken line.

The collective packaging box of the present invention has perforations or equivalent cuts on the bottom plate as shown in the development diagram above, so it can be easily disassembled into a rectangular sheet after use. . That is,
Turn the box over so that the bottom plate is facing up, and use your hands to open the box from the center.
If the bottom plate is torn apart along the cutting line determined by the perforations, etc., and then the adhesion of the tongue piece 13 at the corner part is broken by hand or the tongue piece 13 is torn from its base, as shown in Fig. 4. It becomes a rectangular sheet like (the bottom plate forming part 7 in Fig. 3 is divided into 7a to 7).
It's becoming d. ) The sheet obtained by disassembling the sheet will be correctly rectangular if the sides sandwiching the vertices of two right-angled isosceles triangles whose bases are the short sides of the rectangular bottom plate, and the straight line connecting the vertices of the two triangles above. This is because the bottom plate is torn along the line. If the bottom plate is square, the length of the perforations 12 in the above example becomes zero. In other words, the same result can be obtained by setting diagonal cutting lines on the bottom plate.

In order to facilitate the tearing operation of the bottom plate as described above, the box of the present invention is designed so that a finger can be inserted at an appropriate position on the cutting line (a particularly effective position is the intersection of the cutting lines). It is advisable to provide holes as appropriate. In the above example, part 1 of the ventilation hole provided in the bottom plate
4 and 15 also serve as holes for such a role.

The collective packaging box according to the present invention is easy to disassemble after use, and the shape after disassembly is rectangular, which is convenient for bundling and handling. This is extremely effective in improving the efficiency of waste disposal operations.

Claims (1)

[Scope of utility model registration request] In a corrugated paper collective packaging box in which the top plate, side plates, and bottom plate are made of a single piece of paper, and the top plate is used without removing the hexahedral shape and then discarded, the bottom plate is If the bottom plate is a square, then along the two diagonals; if the bottom plate is a rectangle, the bottom plate should be drawn along the sides that sandwich the vertices of two right-angled isosceles triangles whose base is the short side, and the straight line that connects the vertices of the two triangles. Along the bottom plate, a cutting auxiliary line consisting of perforations or discontinuous cuts having the same effect is provided to facilitate cutting of the bottom plate, and the corner portion between the side plates can be broken by hand. Box for collective packaging.
