Description

[Detailed Description of the Invention] The present invention relates to an assembly type packaging box that is particularly useful for packaging fruits that are easily damaged and damaged, such as grapes and loquats.

Conventionally, this type of packaging box has been proposed to have a structure with double or triple side walls, and this type of prefabricated packaging box has high stacking strength and can withstand stacking in multiple stages. has excellent advantages.

However, if the side walls of the packaging box are made to have a multilayer structure in this way, the amount of paper required to manufacture each box increases, and the manufacturing cost increases accordingly.

The present invention is an attempt to reduce the amount of paper consumed per box in this type of assembled packaging box, and to reduce the manufacturing cost thereof.

That is, the present invention provides an assembly type packaging box that is shaped like a rectangular rectangle without a lid and has left and right side walls 1, 1 double and front and rear side walls 2, 2 triple. The outer side plates 11.11 are connected to each of the left and right sides of the bottom plate 3, and the inner side plates 12 are connected to each of the outer side plates 11 downward from the upper end, while the intermediate side plates 21 of the front and rear side walls 2, 2 .21 is connected to each of the front and rear sides of the bottom plate 3, and the inner and outer front and rear plates located on the inside and outside are divided in half left and right at the intermediate seam 4, and the external front and rear plates 22 are connected to each other. , 22, 22, 22 are the left and right outer side plates 11
．． On both sides of 11, there are also front and rear panels 23.23, 23,
23 are coupled to the upper ends of the off-campus front and rear panels 22.22, 22.22, respectively, and furthermore, an insertion piece 24 that protrudes inward is coupled to the lower end of each off-campus front and back panel 22 on the joint 4 side. Each of the insertion pieces 24 is inserted and fixed into an insertion hole 25.25 at the lower end of the front and rear intermediate face plates 21.21, and each of the inner front and rear face plates 23 has an outer side at the lower end of the corner side. The insertion piece 26 protruding toward the
Each of the insertion pieces 26 is inserted and fixed into each of the notches 13, 13, 13, 13 at the lower ends of both sides of the inner side plate 12.12, and is related to an assembly type packaging box. The inner part 5 is a narrow connecting part formed between the inner and outer side panels 11 and 12 and between the inner and outer front and rear panels 23 and 23, respectively, and these connecting parts 5 are used to assemble the packaging box. 1. 1.2. Constitutes the top surface of 2.

FIG. 1 is a developed view of the packaging box of the present invention, and the product of the present invention can be obtained by punching out the paper according to the developed view.

In FIG. 1, 6 is a fold, and 7 is a cut for forming the insertion hole 25.

When assembling the packaging box of the present invention from the unfolded state shown in FIG. 1, as shown in FIG.
2, 11, 12, external front and rear panels 22 of the front and rear side walls 2.2,
22, 22. 22 and the same half inner front and rear plates 23, 23, 23
.
3, the insert pieces 26 are inserted and fixed into the notches 13 of the inner side plate 12, respectively, and the product of the present invention is obtained as shown in FIG.

The product of the present invention assembled in this way has left and right side walls 1,
1 has a double laminated structure, and the front and rear side walls 2, 2 have a triple laminated structure, and have excellent stacking strength. ．．
24 is inserted and fixed into the insertion hole 25 at the lower end of the intermediate face plate 21, so that the outside front and rear face plates 22, 22 and the outer side face plate 11 continuous thereto are restrained in the assembled state, and furthermore, the inside front and rear face plates 23 are restrained in the assembled state. .23 is attached to the inner side plate 12 at the insert piece 26.26 at the lower corner end thereof.
Since it is inserted and fixed in the notch 13 on both the left and right sides of the
The inner front and rear panels 23, 23 and the inner panel 12 connected thereto at the insertion stop are also restrained in the assembled state, ensuring an extremely robust assembled state.

Figure 4 is an exploded view of a conventional prefabricated packaging box that is assembled so that the front, left, and right side walls are double-layered, and Figure 5 is an exploded view of a conventional prefabricated packaging box that is assembled so that the front and rear side walls are triple-layered, and the left and right side walls are double-layered. The figure shows an exploded view of a conventional prefabricated packaging box.
, a/ is a member corresponding to the intermediate face plate 21 of the product of the present invention,
It extends outward from b'.

Comparing this with the development view of the product of the present invention, the present invention does not have such an overhang of the member A/, and the amount of paper used can be saved by the width corresponding to this overhang, and the amount of paper used can be reduced depending on the size of the packaging box. It has the advantage of reducing the consumption of regular paper, and thus the unit manufacturing cost, by 10 to 20%.
