Abstract

PURPOSE:To obtain a packaging case having such a structure as to permit folding operation to be mechanized easily by a method wherein end pieces are formed extending from the opening end of a case body, the outer end parts of the end pieces are fixed somewhat inwardly of the opening end of the case body and the end pieces between the opening end and the fixed parts are bent to form spaces at the end of the case body. CONSTITUTION:A commodity 4 such as beverage bottle is packed for sale in a packaging case 1 by being placed on a space part 3 provided in a closed end 2 thereof and a lid 5 is provided on an open end thereof. A pair of opposite end pieces 7 are extended from the edges 6 of the closed end 2 and their bonding faces 8a forming the end parts of the end pieces 7 are attached to the inside of the packaging case 1 in such a manner that walls 8b, 8c and 8d of the end pieces are bent along folding lines 9 into an approximate U-shape to define nearly rectangular spaces 3 between the side walls of the packaging case 1. The spaces 3 absorb the shocks from vertical vibration when the commodity 4 in the packaging case 1 is subjected to shocks to cushion the impact on the commodity 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a packaging box for accommodating products such as drink bottles and cosmetics.

[Conventional technology]

Traditionally, packaging boxes such as those shown in Figures 5 and 6 have been used in department stores, pharmacies, etc. to house drink bottles such as nutritional tonics and to be displayed and sold together with the products. Ta.

The packaging boxes (21) shown in FIGS. 5 and 6 have one end as an open end (not shown) and the opposite end as a closed end (22). ) edge (23)
By bending the end piece (24) extending from the box (24) into an appropriate shape and folding it into the inside of the box (21) to form a wall, a space of the required size is formed between the end piece (24) and the main body of the box (21). Ta.

This space serves to buffer the impact applied to the stored item from the outside, to adjust the dimensions between the length of the stored item and the size of the box (21), or even to accommodate a larger box (21).
This has the significance of increasing the consumer's desire to purchase the product by improving its appearance and attractiveness.

[Problem to be solved by the invention]

However, in the conventional box (21), the folding structure of the end piece (24) of the part that forms the space requires manual labor that requires some skill, and furthermore, this folding work is very difficult to adapt to mechanization. There was a problem.

That is, in FIG. 5, the folding operation was performed in the following manner. This corresponds to each adjacent surface (2) of the end piece (24).
5a) The angle formed by (25b) and (25c) is approximately 9
The end piece (24) is folded into the inside of the box (21) from both the left and right sides, being careful to keep the angle at 0 degrees, and the wall forming the space is constructed by folding the end pieces (24) into the inside of the box (21), making sure that the angle is approximately 90 degrees. Otherwise, an appropriate space would not be formed, and conversely, in order to make the angle approximately 90 degrees, it was necessary to have sensory skill with the fingertips that can detect subtle differences.

In addition, in FIG. 6, the pasting surface (26) in the end piece (24) is shown in advance.
Apply glue to a), fold this pasting side (26a) about 180 degrees and adhere it to the inside of the box (21) (27),
Thereafter, in order to form a surface (26b) that comes into contact with the stored object, the edge (28) at the tip of the end piece (24) is attached to the bottom cover (29).
He folded it in with his fingers so that it was perpendicular to it. In this case as well, the same skill as in FIG. 5 above was required.

Due to the recent dramatic increase in the demand for products, it has become impossible to cope with the rapidly increasing consumption of products, which are products to be stored, by the manual labor that requires skill as described above.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to have a structure in which the work of folding the end pieces to form the above-mentioned space can be done simply and manually, and also to easily mechanize the work of folding the end pieces. It is an object of the present invention to provide a packaging box having a structure suitable for assembling an automated production line.

[Means for Solving the Problem] In order to achieve the above object, the present invention takes the following technical means. That is, an end piece is formed by extending from the open end of the box body, and the outer end of the end piece is fixed slightly inside the open end of the box body,
A space was formed at the end of the box body by bending the end piece between the opening end and the fixed part.

Here, a pair of end pieces may be formed from both opposing edges of the opening end, and the bent end pieces abut against a wall forming an end face of the box and an object to be stored in the box. A wall and a wall connecting the two walls may be formed.

Further, the end pieces may be provided at the open end portions on both sides of the box body.

[Effect]

As a result of the above configuration, when the packaging box according to the present invention is bent to form a space, the end piece can be simply pushed in using the fixed part as a fulcrum, and even in the case of mechanization, the desired space can be easily formed. It has a structure that allows for

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the packaging box (1) according to the present invention in an assembled state, in which a space (3) is provided at one of the open ends (2) and the closed end (2). An object (4), such as a drink bottle, is stored in the upper part of (3) and sold. Further, on the upper part, there is provided M(5) on the opening side.

A pair of opposing end pieces (7) extends from the edge (6) on the closed end (2) side, and the attachment surface (8a) forming the tip of this end piece (7) is Other walls (8b) (8c) bent into a U-shape along the bending line (9)
