Inflatable gas bag having auxiliary gas pockets

Abstract

An inflatable gas bag having auxiliary gas pockets is compose of a plurality of gas pocket units, each of gas pocket units includes a main gas pocket of bigger width and a plurality of auxiliary gas pockets of smaller width. A welding line is located between a main gas pocket and an auxiliary gas pocket, and between two auxiliary gas pockets. The conduits are arranged on said welding lines in a predetermined distance, through which gas in the main gas pocket and a plurality of auxiliary gas pockets can be transferred. The gas pocket units are isolated such that gas can not be transferred between each other. In case any main or auxiliary gas pockets are broken, gas could still be contained in other gas pockets units. The present invention provides a plurality of auxiliary gas pockets to absorb the pressurized gas from main gas pocket during impact and therefore be able to protect articles from exterior impact more effectively.

Description

BACKGROUND OF THE IVENTION [0001] 1. Field of the Invention [0002] The present invention is related to an inflatable gas bag having auxiliary gas pocket and particularly to an gas bag that is composed of a plurality of gas pocket units, each of gas pocket units includes a main gas pocket of bigger width and a plurality of auxiliary gas pockets of smaller width. The gas in the main gas pocket and a plurality of auxiliary gas pockets can be transferred through conduits. The inflatable gas bag of the present invention is able to protect articles from exterior impact more effectively. [0003] 2. Brief Description of Related Art [0004] Traditional device for protecting articles packaged therein is bubble wrap. It is able to absorb exterior impact by a plurality of uniform air pockets. The ability of absorbing impact is limited because the air pockets are too small. [0005] U.S. Pat. No. 6,149,002 and U.S. Pat. No. 6,415,920 disclose a container having a wall member, a front panel, and a re...

AI Technical Summary

Benefits of technology

[0006] An object of the present invention is to provide an inflatable gas bag having auxiliary gas pockets which absorb the high pressure gas in main gas pockets during impact, to avoid the main gas pockets broken. Due to damping effect when gas is force to flow from main gas pockets to auxiliary gas pockets through valve in between, impact energy are dissipated more effectively.

[0007] Another object of the present invention is to provide an inflatable gas bag having auxiliary gas pockets, which is able to protect articles from exterior impact more effectively.

Problems solved by technology

The ability of absorbing impact is limited because the air pockets are too small.

Most of the air pockets may be broken at the same time under severe mechanical shock when over pressure build up in the bubbles.
