The invention relates to a pouch (1) for a pressurized bottle, made up of a tubular wall (2) closed in its upper part (22) by a welded seam into which a valve (4) is incorporated. According to the invention, the tubular wall (2) is obtained by overlapping and welding together the two lateral edges of a strip, and the tubular wall (2) is closed in its lower part (21) by an essentially round bottom wall (3). Thus, the tubular wall (2) 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 (22) where it becomes completely flat. The pouch (1) will, at least in a major lower part, occupy practically all the space in the bottle, considerably reducing the dead space in that part.
L'invention concerne une poche (1) pour flacon pressurisé, composée d'une paroi tubulaire (2) fermée dans sa partie supérieure (22) par une soudure dans laquelle est intégrée une valve (4). Conformément à l'invention, la paroi tubulaire (2) est obtenue en chevauchant et en soudant les deux bords latéraux d une bande et la paroi tubulaire (2) est fermée dans sa partie inférieure (21) par une paroi de fond (3) essentiellement ronde. Ainsi, la paroi tubulaire (2) de la poche aura une section transversale quasiment circulaire dans une grande partie inférieure, cette section tendant à devenir elliptique en s approchant de l extrémité supérieure (22) où elle est totalement plate. La poche (1) occupera, au moins dans une grande partie inférieure, pratiquement tout l espace du flacon, diminuant considérablement l espace mort dans cette partie.
