Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging box, and more particularly to a connection structure between boxes housing lightweight articles.

Generally, this type of packaging box improves the efficiency of cargo handling.
means for collectively holding packaging boxes together with cable ties;
Alternatively, methods such as stacking a large number of packaging boxes into larger outer boxes have been adopted.

However, the former method requires equipment for the binding band and strapping, and also has the problem that the edge of the box may be crushed or the band may become loose during binding.

In the latter case, the workability during cargo handling is good, but on the other hand, it requires a separate outer box, which has the disadvantage of increasing material costs.

This invention was made to eliminate the above-mentioned drawbacks.
A part of the opposing bent piece connected to the opening edge of the box body has a clamping groove, and forms a connecting piece that is removable from the connecting part, and the other opposing bent piece has a clamping groove. The object of the present invention is to provide a packaging box that enables mutual connection between the boxes without the need for secondary materials such as cable ties by providing an insertion groove on the main body side of the connecting part to receive the connecting piece from the clamping groove. shall be.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a packaging box, which includes a box body 1a, inner folding pieces 3, 3 and outer folding pieces 4, 4 which are bendably formed at the opening edge via a connecting part 2 and cover the upper and lower surfaces of the main body 1. are provided so as to face each other when the main body 1a is assembled.

Reference numerals 5 and 5 denote connecting pieces that are removable through a notch 6 and a perforation 7 made in the connecting part 2 in a part of the opposing inner bent piece 3.3 on the upper surface side, for example. .

A clamping groove 8 having a length of about half the width of the connecting piece 5 is cut out in the middle part of the connecting piece 5 from the edge toward the main body 1a, and the width of the groove is twice as large as the side surface of the main body. It is formed so that it can be held.

Reference numeral 9 denotes an insertion groove, which is provided at both ends of the side surface of the main body 1a of the connecting portion 2 of the upper outer bent pieces 4, 4, and its length is approximately equal to the length of the clamping groove 8, and the groove width is equal to that of the connecting piece 5. The thickness is approximately equal.

Next, the procedure for connecting packaging boxes will be described.

First, the box main body 1a is assembled, the inner and outer bent pieces 3 and 4 on the lower surface side are sealed with adhesive tape 10, and assembled as shown in FIG. 2, and a packaged object (not shown) is placed inside.

). Next, as shown in the third figure, a lid is formed by the inner bent pieces 3, 3 and the outer bent pieces 4, 4 on the upper surface side, with the connecting piece 5 left in the open state, and the outer bent pieces 4, 4. The abutting portion is sealed with adhesive tape 10.

When connecting a plurality of packaging boxes 1, 1 formed as described above, first, as shown in FIG. What is necessary is to insert the cut out coupling piece 5 into the adjacent insertion grooves 9, 9 of the base boxes 1, 1 through the clamping groove 8, as shown by the dotted lines in the figure, and to clamp the side surface of the main body 1a which is continuous with the insertion groove 9.

Therefore, the base boxes 1, 1 can be easily and firmly connected.

Also, if you want to cancel the connection, just move each box in the opposite direction.

As described in detail above, the present invention includes each pair of bent pieces disposed on the box body via a connecting part, and one of the opposing bent pieces has a clamping groove in a part thereof so as to be removable. Since the packaging box is equipped with a connecting piece and an insertion groove that receives the connecting piece from the clamping groove provided on the connecting part body side of the other opposing bent piece, the connecting piece must be removed when connecting. Since the cut-out connecting pieces can be inserted into the insertion grooves and connected, there is no need to prepare any other auxiliary materials in addition to the cable ties, which has the advantage of making it possible to significantly reduce the cost of packaging materials.

Furthermore, when a large number of packaging boxes are stacked on a pallet, it has the excellent advantage of being able to completely prevent collapse of the cargo that occurs when the pallet is transported by forklift or truck by being continuously connected using the connecting pieces. are doing.

In addition, in the embodiment, the coupling piece was described on the top lid side of the box body, but the present invention is not limited to this, and the coupling piece may be provided on the bottom bottom side of the box body.
