Description

[Detailed Description of the Invention] This invention relates to a packaging box that can be divided and connected in the vertical direction.

Conventionally, customers have various requests for the number of items to be packed in one case, such as 1 dozen, 2 dozen, or 3 dozen, so we have used boxes for 1 dozen and boxes for 2 dozen. , 3-dozen boxes, etc., had to be prepared in advance, which caused a considerable amount of time and effort in managing packaging materials.

The purpose of this invention is to solve the problems mentioned above.

That is, this invention provides an upper opening-like body member in which a pair of side walls and a pair of end walls are erected on a bottom wall, and a connecting wall is protruded from the upper edge of the pair of side walls through a separating means such as a perforation. It consists of a lid member with a U-shaped cross section that connects connecting walls to both ends of the lid wall, and multiple pieces can be stacked vertically and connected together through these connecting walls. It is designed so that it can be divided into one box, two connected boxes, three connected boxes, etc., as appropriate using a separating means, and is particularly useful for flat boxes. In addition, the packaging box is easy to mechanically package, and there is little wastage of materials.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings. The packaging box of this invention is shown in Figures 1 to 3.
As shown in the figure, there is a rectangular parallelepiped-shaped body member A made of cardboard or other thick paper with an open top, and this body member A.
It is combined with a lid member B having a U-shaped cross section to close the upper opening of the lid.

In the body member A, a pair of side walls 3 are connected to both side edges of a rectangular bottom wall 1 via a polygonal line 2, and a pair of side walls 3 are connected to each other through a polygonal line 4 at both end edges of the bottom wall 1. A pair of lower end walls 5 are connected, a folding wall 6 is connected to both ends of the side wall 3 via a fold line 4, and a narrow connecting wall 8 is connected to the upper edge of the side wall 3 via a fold line 7. This connecting wall 8 is provided with transverse perforations 9 along the fold line 7.

The fold line 7 is formed into a half-cut shape in which the back liner and the center core are cut while leaving the front liner, so that the connecting wall 8 is easy to open outward and easy to cut.
A picking notch 10 is provided at one end of the perforation 9 to form a separating means. Note that the cutting means is not limited to the half-cut fold line and the perforation as described above, and two perforations, a cut tape, or the like may be provided.

The body member A is assembled by folding the end wall 5 on the outside of the folding wall 6 and bonding it with adhesive.

The lid member B has a joining wall 13 at both ends of a lid wall 11 having the same shape as the bottom wall 1 of the body member A through a fold line 12.
are connected to each other, and can be fitted into the inner opening of the connecting wall 8 of the body member A, and the joining wall 13 is adhered to the outer surface of the folding wall 6 to perform packaging. At this time, making the end wall 5 and the joining wall 13 butt each other is effective in reducing the amount of material, and by making the end wall 5 smaller and the folded wall 6 smaller, the overlapping part at the end becomes smaller and the material surface It is possible to reduce costs.

As shown in FIGS. 4 and 5, a plurality of packaging boxes of this invention can be vertically stacked and connected using connecting walls 8 protruding from both side edges of the body member A. That is, the connecting walls 8 are stacked with the connecting walls 8 facing outward, and the connecting walls 8 of the lower box body are bonded to the outer surfaces of the side walls 3 of the upper box body with an adhesive. Note that, for the topmost box, the connecting wall 8 on the top surface of the lid member B is folded over and bonded.

The packaging boxes connected in this way are separated by the pull member A with the knob at the end of the perforation 9, which is the separating means.
It can be easily separated by cutting the connecting wall 8 from the connecting wall 8.

The packaging box according to this invention has the above-mentioned structure. For example, if one dozen items are stored in one box and multiple items are connected together, the number of boxes to be handled will be reduced, making transportation and storage easier. It is advantageous that wholesalers etc. can tear it along the perforations and divide it into 1-dozen single pieces, 2-dozen pieces connected together, 3-dozen pieces connected together, etc. according to the customer's order. It is very convenient because it allows you to prepare boxes of various sizes depending on the number of items to be packed, such as 1-dozen boxes, 2-dozen boxes, 3-dozen boxes, etc., as in the past. Packaging costs can be reduced as there is no need to store the packaging, the number of packaging boxes is reduced and the time and effort required to manage packaging materials can be eliminated, and the simple shape facilitates mechanical packaging. In addition, in flat packaging boxes, there is little wastage of materials, making them extremely useful.
