Abstract

Liquefied gas tank that is easy to manufacture and quick to use, and bag for sealing ducts for cables which includes said tank. The tank has rupture means for inflating sealed compartments, comprising a main tube (1) that is closed at one end, an outlet tube (4) inserted at the other end of the main tube via a first end (6) and closed at the distal end thereof, in which the outlet tube has a narrow portion (5) that defines a point of rupture and an inner orifice (8) that runs from the first end of the outlet tube to the narrow portion (5), towards the distal end, and in which the dimension of the narrow portion (5) and of the orifice (8) and the length of the outlet tube (4) are determined in such a way that a lever force between 19N and 80N causes the outlet tube (4) to rupture at the point of rupture (5), releasing the liquefied gas through the orifice (8).
