Abstract

(57) [Summary] [Purpose] Using a continuous piece of paper, create a buffer structure inside the outer box. [Structure] A tubular box is formed by using a sheet of paper, and a buffer having a size slightly smaller than that of the same paper is placed inside the outer box. A spacer is formed so as to protrude outward along the bending line of the buffer body, and the tip of the spacer is brought into contact with the inner wall surface of the outer box. [Effect] Since the box body and the buffer body are made of a single piece of paper, automatic packaging is possible, and since synthetic resin is not used, no pollution occurs at the time of disposal.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging box for accommodating bottles, and more particularly to a packaging box integrally formed with a cushioning mechanism for cushioning an article to be packaged.

[0002]

[Prior art]

 When packaging bottles that are liable to be damaged by an external impact, it is common to store the bottles in a cushioning material in advance and package it together with this cushioning material.

As such a cushioning material, a cushioning body made of a styrofoam molded product is used when the bottles to be accommodated are large, and meat is used when the bottles to be accommodated are small bottles such as drinks. A buffer sheet formed by heat-molding a thin synthetic resin film was used.

[0004]

[Problems to be solved by the device]

 However, in such a conventional structure, since a synthetic resin material such as styrofoam or synthetic resin film is used as a cushioning material, there is a drawback that when used packaging materials are disposed of, there is a drawback that pollution is caused. In this case, it is necessary to store the bottles in the cushioning material one by one one by one, so it cannot be applied to the cartoner that automatically stores the bottles in the box at the same time when the box is formed, and the packaging cost rises. There was a drawback that caused it.

[0005]

[The purpose of the device]

 The present invention has been made in view of the above circumstances and intends to cope with this. The present invention uses a material (paper or the like) that forms the box body, and is configured to integrally form a buffer body in the box body. It is intended to provide a packaging box.

Another object of the present invention is to provide a packaging box that can avoid the use of a material that causes pollution and can reduce the packaging cost.

[0007]

[Key points of the device]

 The present invention is an outer box formed by using a continuous sheet of paper, and a box body that is continuous with the outer box and has a buffer body formed with a constant gap inside the outer box. The front wall, the right side wall, the rear wall and the left side wall are successively connected through the bending line, and the lid plate and the bottom plate are foldably connected to the upper and lower ends of the front wall. Each end has a structure in which a closing tongue is connected continuously, and the buffer body is connected to the outside of the left side wall forming the outer box, and the front buffer wall, the right buffer wall, the rear buffer wall and the left buffer wall are bent. The glue margin is continuous on the outside of the left side wall of the buffer, and the fold line between the front wall of the buffer and the right wall of the buffer, the fold line of the right wall of the buffer and the back wall of the buffer, and the back wall of the buffer and the left of the buffer The fold lines with the front wall are engraved with several spacers along each fold line. It has been a main point of devising a box for packaging with a buffer structure you are.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The packaging box of the present invention is made of the same paper as the outer box A formed by using a continuous sheet of paper, and is positioned with a certain gap inside the peripheral wall of the outer box A. It is configured by the buffer body B to be driven.

In the outer box A, a front wall 1, a right side wall 2, a rear wall 3 and a left side wall 4 are sequentially connected through folding lines 13 ... 13, and a lid plate 11 and a bottom plate 12 are provided at both upper and lower ends of the front wall 1. It has a publicly known structure in which the closing tongue pieces 21, 21 and 41, 41 are continuous at the upper and lower ends of the right side wall 2 and the left side wall 4, respectively.

The buffer B is formed continuously on the outer side of the left side wall 4, and the front buffer wall 5, the right buffer wall 6, the rear buffer wall 7 and the left buffer wall 8 are bent via folding lines 14 ... And a glue margin 9 is continuous on the outside of the buffer left side wall 8.

The spacers 15 ... 15 are formed along the bending lines 14 ... 14 of the buffer B, and are formed so as to project outward when the buffer B is formed.

As shown in FIG. 1, the engraving direction of the spacers 15 ... 15 is such that the base end is located on the side of the bending line 14 and the tip of the spacer protruding when the buffer B is assembled is folded. In addition to the case of projecting from the side of the bending line 14 toward one of the buffer walls, it may also be engraved so as to project alternately on both sides of the bending line 14 as shown in FIG. it can.

If the engraving directions of the spacers 15 are alternately formed as illustrated in FIG. 5, when the packaging box is assembled, the tip ends of the two spacers 15 and 15 which are alternately projected in different directions are arranged in the outer box A. It is excellent in that it can be brought into contact with each of the two side walls and an even gap can be formed between two adjacent side walls.

The width of each wall surface (the front buffer wall 5, the right buffer wall 6, the rear wall 7, and the left side wall buffer 8) forming the buffer B is larger than the width of the wall surface forming the outer box A. It is formed to be a little smaller. Specifically, it is configured such that the total size of the width of the spacer 15 and the width of each wall of the buffer body matches the inner size of each wall of the outer box A. .

Further, as for the height of the wall surface forming the buffer B, all the wall surfaces can be formed to have the same size as the height of each wall surface of the outer box A as illustrated in FIGS. 1 to 5. However, in order to facilitate the insertion of bottles during the automatic packaging, it is desirable that the upper end of the wall surface forming the buffer B be slightly inclined as shown in FIG.

Reference numerals 16 ... 16 denote projecting ridges for buffering which are formed in steps on each of the wall surfaces forming the buffering body B. It is possible to more accurately support the peripheral body portion of the contained bottles.

[0018]

[Effect of device]

 The effects of the present invention are as follows.

(1) Since the cushioning body B is integrally formed inside the outer box A by using the paper forming the outer box A, the whole body can be easily formed in conjunction with the assembling operation of the box body. it can.

(2) Since the buffer B is accurately maintained between the inner surface of the outer box A and the spacers 15 ... 15 formed on the bent portions of the respective peripheral walls, the buffer effect can be accurately exhibited. .

(3) Since no buffer body formed of expanded polystyrene or a synthetic resin film is used, no pollution is generated at the time of disposal.

(4) It can be applied to various things such as a packaging box for storing a large bottle to a packaging box for storing a small bottle such as a drink by simply changing the thickness and size of the paper to be used. It is versatile.

(5) When the buffer ridges 16 ... 16 are formed on the peripheral wall of the buffer B, since the outer peripheral portion of the peripheral body of the cylindrical bottle is supported by the ridges 16 ... Very accurate cushioning support is possible.
