Abstract
The invention relates to a pouch for a pressurized bottle, made up of a tubular wall closed in its upper part by a welded seam into which a valve is incorporated. According to the invention, the tubular wall is obtained by overlapping and welding together the two lateral edges of a strip, and the tubular wall is closed in its lower part by an essentially round bottom wall. Thus, the tubular wall of the pouch will have a practically circular cross section in a large lower part, this cross section tending towards an elliptical shape as it nears the upper end where it becomes completely flat. The pouch will, at least in a major lower part, occupy practically all the space in the bottle, considerably reducing the dead space in that part.
