Abstract

The utility model relates to a gas-filled packaging bag, which comprises a bag body whose bag mouth is open, a plurality of mutually independent strip-shaped confined chambers which extend along the direction that is perpendicular to the flat surface where the bag mouth is arranged are distributed on the bag body. The strip-shaped confined chambers are filled with compressed air. The strip-shaped confined chambers extend to the bag bottom position that the bag body is faced to the bag mouth. The packing bag as a package of the prior market sailing commodity can provide excellent insulating and cushioning functions.

Description

Gas flushing pouch

Technical field

The utility model is a kind of gas flushing pouch, particularly by plastics, nylon, plastics---raw material preparing such as nylon synthetic material constitute the packaging bag or the air bag that can in this liner, charge into gas of its liner by the bilayer film sheet.

Background technology

For avoiding instrument in storage and transport process, to be clashed into, clog some protectiveness materials in the space after the article vanning usually, as waste paper, plastics, sponge etc.Though can play buffer action to a certain degree like this; but because these materials are difficult to realize uniform filling usually, make it be difficult on all directions, provide uniform cushion effect, and these protectiveness materials were used promptly and were abandoned to instrument; no longer therefore repeated usage can cause environmental pollution.Especially for exact instruments and equipment, it is unfavorable adopting this manner of packing.

The utility model content

The utility model purpose is to provide a kind of gas flushing pouch, and this gas flushing pouch can be treated connection with wrapping of piece the actv. buffer protection is provided, and can reduce the pressure of environmental protection.

According to above-mentioned purpose design-calculated gas flushing pouch, comprise bag with a unlimited sack.On bag, be distributed with several along the separate bar shaped confined chamber that extends perpendicular to the direction on plane, sack place.Be filled with pressurized air in these bar shaped confined chambers.The bar shaped confined chamber extends to the bag bottom position relative with the sack position of bag.

Preferably, aforementioned gas flushing pouch, its bar shaped confined chamber distributes equably along the ring space at sack place.

Gas flushing pouch of the present utility model, several the separate bar shaped confined chambers that extend along perpendicular to the direction on plane, sack place are set on the bag of pocket-like, and after making the bar shaped confined chamber extend to the position, bag bottom relative of bag with the sack position, packaging bag is formed on carry on its bag the air-sprung airbag, and then particularly precision instrument and external environment condition have for example obtained good buffering effect between hard or the rigid package vanning at article to be packaged by air-sprung air shock-absorbing damping characteristics.Simultaneously, this gas flushing pouch can be applied to the packing of similar articles or other article repeatedly after using first, thereby avoids the pressure recovery because of using other closely knit packing thing to cause.

The specific embodiment

Referring to Fig. 1 a, 1b, 2, show the structure of the utility model gas flushing pouch.

This gas flushing pouch B, be by four layers of plastic film mutually stacked after, its periphery part of cracking is fixed by hot melting mode fusing after cooling, reserve sack simultaneously, and formed bag after in corresponding confined chamber, charging into gas.

See Fig. 1 a, at first the double-layer plastic diaphragm mutually stacked after, its periphery part of cracking is fixed by hot melting mode fusing after cooling.Dotted line framework shadow region e shown in Fig. 1 a represents mutually the stacked double-layer plastic diaphragm periphery part melting welding position of cracking.Through the double-layer plastic diaphragm after the melting welding, its dotted line framework shadow region e integral body in appearance is the broach shape, and the gap between the dotted line framework shadow region e becomes the blister cavities c of hollow.The port of blister cavities c leaves as yet the inflation inlet a of not melting welding sealing-in.The position of inflation inlet a generally is designed near the sack of gas flushing pouch B.Blister cavities c is evenly distributed and keep separate in the mutually stacked same direction in double-layer plastic diaphragm upper edge.Each blister cavities c forms a melting welding zone d at the about medium position of self, and the two layers of plastic diaphragm is fused together at melting welding zone d, but does not hinder the gas fluidity among the blister cavities c.The effect of melting welding zone d is to prevent to form spherical or ellipsoid shape after the blister cavities c overinflation, so that reduces the effective volume of the gas flushing pouch B that hereinafter forms, so all visual actual needs of quantity and position of melting welding zone d is determined.

See Fig. 1 b, 2, consult Fig. 1 a simultaneously, the about medium position doubling of double-layer plastic diaphragm shown in Fig. 1 a along blister cavities c strip shape direction, form four layers of stacked plastic film mutually, the edge that four layers of plastic film the are parallel to blister cavities c strip shape bearing of trend part h melting welding again of cracking is fixed again, can obtain remaining to be poured the packaging bag of gas.Afterwards, blister cavities c is charged into pressure gas via inflation inlet a makes pressure in the blister cavities c greater than atmosphere outside, even, finally make blister cavities c form separate sealed gas chamber with inflation inlet a experience melting welding after cooling bonding (the two layers of plastic diaphragm dotted line framework shadow region f that is positioned at the drawing rear shown in Fig. 1 b represents the position at inflation inlet a place).Similarly, the also visual actual needs in the quantity of blister cavities c and position is determined.Be folded into four layers of plastic film through the double-layer plastic diaphragm, and charge into the gas flushing pouch B of pressure gas in blister cavities c, its folding position b need not to carry out melting welding at this position and operates because of the continuity of plastic film.Like this, the bag bottom position g with the cooresponding gas flushing pouch B of folding position b also carries the blister cavities c (referring to shown in Figure 2) that can be used as liner naturally.The result, after gas overcharging, gas flushing pouch B just becomes and has the packaging bag as its liner with a plurality of independent closed air chamber c, and it also still can keep other liner position to have good isolation and buffering effect the damaged situation of one of sealed gas chamber c occurring.
