In a double chamber container, the inner chamber is formed by a tubular body in an elastic rubbery material stretched in order to expel a pressurised substance against its own elasticity. To obtain a precise stretching ratio of the hose (1) and to empty it as well as possible, the hose converges uniformly and its walls have a uniform thickness, even in their bottom part (9). To attach the hose (1) to the container, a collar (11) which acts also as a seal is formed on the hose. |
