In a gas cartridge, inside of a metal made outer canis arranged with a metal made inner bagcharged with a fuel gas G. A space between the outer canand the inner bagis charged with a compression gas Gfor pressing to crush the inner bagin accordance with consumption of the fuel gas G. Pertinent positions on an inner side of the outer canare provided with deformation introducing members Pthrough Pfor producing an initial deformation for introducing a deformation of the inner bag when a press force of the compression gas Gis received.

Gas cartridge

Fuel gas or some other kind of fluid is stored in a collapsible metallic bag that is attached to a valve and is stored inside a rigid outer container. Between the rigid outer container and the collapsible bag is a space or volume filled with compression gas during use which puts a collapsing pressure evenly upon the bag. In order to reduce bag failures, the outer surface of the collapsible bag has a series of projected streak portions that project outwardly from the vertical length of the collapsing in several locations that prevent the bag from expanding to fill the entire space between the rigid outer container and the bag. These projected streaks form recessed portions in the bag's surface which facilitates the bag collapsing in those predetermined locations evenly which in turn reduces the collapsible bag's failure rate from breaking during operation.
