Embodiment Construction

[0018] Referring to FIG. 1, the inflatable gas bag of the present invention is composed of a plurality of gas pocket units 10. Each of gas pocket units 10 includes a main gas pocket 11 having bigger width and a plurality of auxiliary gas pockets 121, 122 having smaller width. The two auxiliary gas pockets are shown in the figure as example, and is not meant to limit the number of auxiliary gas pockets for the invention. The width of the main gas pockets 11 are 1˜2 centimeters wider than auxiliary gas pockets 121, 122. By way of example only, if a main gas pocket 11 is formed as three centimeters in width, the auxiliary gas pocket 121, 122 may be formed about two centimeters in width; or if a main gas pocket 11 is formed as four centimeters in width, the auxiliary gas pocket 121, 122 may be formed about three centimeters in width. A welding line 31 is located between a main gas pocket 11 and first auxiliary gas pocket 121,and another welding line 31 is located between first auxiliary...

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...
