Abstract

PURPOSE:To obtain a shock-absorbing material, encapsulating a high pressure and capable of being bent or deflected, by a method wherein two sheets of composite films are put together to form pouched parts and flat parts alternately. CONSTITUTION:A shock-absorbing material 1 is formed by using two layers of plastic films. High-pressure pouched parts 4 are formed by an upper layer film 2 with a predetermined space from one side S1 of a material sheet to the other side S2 thereof so as to have semi-cylindrical shape. An lower layer film 3 is bonded to the film 2 by heat seal except the high-pressure pouched parts and thus the flat parts 5 are formed. High-pressure air, having the pressure of 1kg/cm<2> or higher, is encapsulated in the high-pressure pouched parts 4, therefore, the material 1 stands well against a high external load and developes a shock-absorbing effect. It is easy to bend the material sheet 1 in parallel to the length of the sheet at the flat parts 5. The material 1 is wound around a glass bottle A and is accommodated into an outer box B. The flat parts may be bent along the corner of the box.

BACKGROUND ART Conventionally, a material called an air cap has been widely used as a cushioning material filled with air. This is a plastic film with many small circular air sacs filled with air protruding from key points, but since conventional cushioning materials like this only contain air at normal pressure, the damage is minor. It can be used as a cushioning material to wrap heavy objects, to partition and protect surfaces between objects that are subject to heavy loads, and to fill gaps in objects during transport that may be handled roughly. , there is a problem that the air sac may burst and cannot be used.

On the other hand, air mats, which are inflated by blowing high-pressure air between two sheets over the entire surface, have high elasticity and impact resistance and can withstand high loads, but the high internal pressure causes resistance. This makes it difficult to bend or deform, making it unsuitable for wrapping around round objects or folding in half.
The main problem is that it is only suitable for flat applications.

In order to achieve the above object, the high-pressure encapsulated cushioning material of the present invention is produced by laminating two plastic films, particularly thermoplastic plastic films (also called hasheets), more preferably composite films of polyethylene and polyester, and forming a gap between the films. It is possible to sort materials with a finite length by alternately forming pneumatic pockets (pouch parts) filled with high-pressure gas and flat parts made by bonding two films together by heat sealing or the like. As the high-pressure gas to be sealed, it is preferable to use high-pressure air of 1 kg/ci or more (1') because it is inexpensive, but other gases may also be used.

FIG. 1 is a perspective view showing a first embodiment of the cushioning material of the present invention. The cushioning material 1 of the present invention is basically formed using two layers of plastic films (or sheets), particularly two layers of composite films of, for example, polyethylene and polyester.

The lower film 3 is flat and is hermetically bonded to a portion of the upper film 2 other than the high-pressure pouch portion by heat sealing to form a flat portion 5. High pressure J? Since high-pressure air of, for example, 1 kli/CJ or more is sealed inside the interior part 4, it can withstand high external loads and exhibits a buffering effect. Since it is difficult to bend the high-pressure edge part 4 at right angles to the length direction (t), the material sheet 1 as a whole cannot be folded in this way, but the flat part 5 has a bending resistance. Since there are no holes, it is easy to bend the material sheet 1 parallel to the length t) in the plane portion 5.

FIG. 2 shows an example in which material 1 is wrapped around an object to be packaged, for example a glass bottle A, and placed in an outer box B for cushioning and gap filling. Since the circular top of the high-pressure pouch section 4 is in direct contact with the surface of the bottle A, it elastically tightens the bottle A to prevent it from wobbling or jumping, and also prevents large shocks or loads from being applied from outside the box. The high-pressure pouch section 4 absorbs and absorbs this material, thereby providing good cushioning and protection for the packaged item. Since the flat part 5 is flexible, it can be bent to follow the corners of the box.

As shown in the figure, two plastic films 2 and 3 (the width of which is equal to t in FIG. 1) are introduced in the direction of the arrow ■ through the high-pressure cut-off passage 10 as described above, and pass through the liquid 11. and enter the hyperbaric chamber 12. The films 2 and 3 are guided separately by idle rolls 14, 15 and are first dried (water droplets removed) in a drying section 16. The drying section 16 shown by the solid line may be installed at a position where the inner surface of the film is particularly irradiated as shown by the chain line 16' so as to dry particularly the inner surface of the film 2 well. Then, one film 2 is heated and pressurized in the pouch forming section 17 so that it bulges and deforms to the side opposite to the other film 3. This process is
In the illustrated example, since the feeding is intermittent, the feeding of the film 2.3 is also made intermittent in synchronization with the timing. but,
If a rotating roll pouch forming device is used, continuous feed may be provided. The bulging part 4a in the molding part 17
The formed film 2 and the flat film 3 are then brought together on their inner surfaces in a roll 18 and enter a heat sealing section 19. In the heat-sealing section, the areas between the bulges and both sides of the film (SI r 82 in FIG. 1) are crimped by heat-sealing so as not to crush the bulge 4a. The high-pressure gas is taken in as it is, and a sealed high-pressure gas inside part 4 and a flat part 5 therebetween are formed. In the illustrated example, the operation of the heat sealing section 19 is also performed intermittently in synchronization with the operation of the forming section 17 described above, but it can also be operated continuously.

Then, the two layers of film that have been joined together pass through the exit roll 18' and pass through the exit high pressure cutoff passage 20.
The liquid enters the liquid column 21, rises within the liquid column 21, is taken out in the direction of arrow O, and undergoes appropriate post-processing such as drying and cutting.
This results in a cushioning material sheet 1 of finite length as shown in the figure. Note that 22 shown at the lower end of the passage 20 is an id for allowing the inside part 4 to pass through smoothly.

The above explanation assumes that the high voltage/4' inner part 4 is formed only on one side 2 of the film, but if the method shown in principle in FIG. A cushioning material 31 formed by opposing the pouch portions 4 and 4' to both films 2 and 3 can also be easily manufactured. For this purpose, a molding part is provided for the film 3 as well, as shown by the chain line 17', and a bulging part (not shown) symmetrical to the bulging part 4a of the film 2 is formed synchronously, and heat sealing is performed. In the portion 19, the periphery of this opposing bulge may be heat-sealed to form an opposing high-pressure nouch portion (see 34 in FIG. 7) and a flat portion (35) therebetween.

Although the high-pressure encapsulated buffer material of the present invention can be produced relatively easily using the above-described apparatus and method, if the gas to be encapsulated is to be high-pressure, the high-pressure cutoff passage must be installed very high. , impractical. Corresponding to such a case, FIG. 6 schematically shows a modification of the high pressure cutoff passage. Although the illustrated modification shows only the outlet side 12b of the high pressure chamber 12, the inlet side can also be provided in a symmetrical structure. In this modified high pressure shutoff passage, the outlet pipe part 12b, the high pressure liquid 21' filling pipe part 20f, and the upright passage pipe 20a form a substantially U-shape, and the inside of the high pressure chamber 12 is changed depending on the pressure of the high pressure liquid 21'. kg/c-rI or more, the height of the vertical passage pipe 20a can be made to be about a fraction of the height of the vertical pipe 20 shown in FIG. A branch pipe 20b is extended from near the upper end of the short vertical passage pipe 20a for liquid circulation.
The lower end of 0b is open to the atmosphere. Here, the pressure of the liquid 21 is released, the expanded receiver is collected in the vessel 20c, and the conduit 20d
is sent to a pressurizing source, for example, ton 7'P.

The pressurized high-pressure liquid 21' is supplied to the cylinder 76P through the conduit 20e.
Most of the gas is pushed into the high-pressure pipe section 20f, where it exerts pressure in the direction of the arrow f and balances with the high-pressure gas in the high-pressure chamber 12. In order to prevent the high-pressure liquid 21' from leaking into the upright passage pipe 20a as much as possible, it is preferable to form a constricted part 20a' in the passage pipe 20a to the extent that it does not prevent passage of the pouch part 4. Such a modification makes it possible to make the device more compact and to increase the pressure of the sealed gas.
