Abstract

PROBLEM TO BE SOLVED: To securely protect a transporting article with pushing forces, by partitioning an sealed bag inside into at least two independently divided and expanded chambers by pressure-welding partition seal lines and providing air- injection openings with a check valve connected to respective independently divided and expanded chambers. SOLUTION: A sealed bag body 1 is closely stuck at the whole peripheral edges by a pressure-welding seal line 2. The inside is provided with zigzag pressure-welding seal lines 3. The bag body 1 is divided to two blocks 4, 5. The pressure-welding seal lines 7 reduce the relatively spacious area of respective blocks 4, 5 and the check valve 8 is connected to the two blocks 4, 5. A path 13 connected to the block 4 and another path 14 connected to the block 5 are provided by the interposition of a pressure-welding seal line 3 and the check valve 15 is positioned thereon. Air is sent to the two blocks 4, 5 of the sealed bag 1 in common through the check valve to expand the blocks. The blocks are folded to two parts to form an endless cylinder body. An article A to be transported is put therein to protect it.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock-absorbing package suitable for carrying parcels, particularly glass bottles and other fragile articles.

[0002]

SUMMARY OF THE INVENTION The object of the present invention is to provide a package which can reliably protect and transport a conveyed product with an extremely simple structure and, in particular, does not affect the object to be packaged even if a part of the package is damaged. To provide.

[0003]

The means of the present invention are as follows. It is composed of an endless tubular or bag-shaped main body of an airtight material whose entire circumference is sealed, and the airtight bag is divided into at least two independent divided swelling chambers by crimping partition seal lines. A shock-absorbing package that has an air inlet with a check valve that communicates with each split expansion chamber.

[0004]

EXAMPLE First, a first example shown in FIGS. 1 to 3 will be described.

Reference numeral 1 denotes a hermetically sealed bag formed of an airtight material, the entire periphery of which is adhered by a crimp seal line 2. In addition, a zigzag pressure-bonding partition seal line 3 is provided inside, and the bag body 1 is divided into two blocks 4 and 5. Reference numeral 7 is a crimp seal line that reduces a relatively large space between the blocks 4 and 5. 8 is a check valve that communicates with the two blocks 4 and 5, and is a crimp seal wire 3
Is divided into a passage 13 that communicates with the block 4 via a block and a passage 14 that communicates with the block 5, and the check valve piece 1
5, from which air is commonly sent into the two blocks 4 and 5 of the sealed bag body 1 by pressure to swell, and the blocks 4 and 5 are bent into two to form an endless cylinder (see FIG. 10). In the meantime, the article A is intervened and protected. Reference numeral 17 denotes an air inlet of the check valve 15. In FIG. 11, a bag-shaped body 1'is used.

Next, in the example of FIG. 4, a large number of check valve pieces 15 are formed in series from one common inlet 16 on which the release agent 18 is printed above several passages 14, and FIG. The example shows an example in which inlets 16 are provided on the left and right sides, and many check valve pieces 15 are arranged in a line between them.

7 and 8 show a straw-shaped elongated hole 24.
And the left and right sides are bonded 21 and 22 to provide a check valve 23,
After pneumatically feeding, the elongated hole 24 of the check valve 23 is crushed by air and closed to perform a check function.

In FIG. 9, the sealed bag 1 is placed in a kraft paper bag 20 and a play 25 is provided between the sealed bag 1 and the kraft paper bag 26.
To form Further, the check valve 8 is led out to the outside of the kraft paper bag 26. Thus, the play 25 increases the cushioning property, resulting in a safer package.

[0009]

According to the present invention, by at least two independent bulging chambers, the conveyed product A is pinched and fixed by the pressing force and does not move.

Further, even if air leakage occurs in one of the bulging chambers, the remaining complete bulging chamber supports the self-weight of the article A, and the air in the bulging chamber where the air leakage occurs is the same as the external pressure. Saves the lowest packing effect because it saves in the state air volume. Further, in the case of the two-part swelling chamber according to the example of FIG. 2, the two-part swelling chambers must be divided so that when they are formed into a tubular shape or a bag shape, they are mutually facing surfaces. Otherwise, the above effect cannot be created.

In the example of FIG. 4, relative surface property is not required.

In the case of the example shown in FIG. 9, a space 25 is formed between the cover of kraft paper or the like and the main body, and this space is used as a play against external pressure so as to protect the main body more safely.
