ABSTRACT OF THE DISCLOSURE "Improvements in dispensers" A dispenser for dispensing liquid and paste-like compositions has an inner flexible container for receiving the composition and a pressure-resistant outer container. A propellent gas is introduced through a filling valve into the annular chamber between the con- tainers. The composition in the inner flexible container is thereby pressurized and can be dispensed by actuation of a dispensing valve whose base closes the mouth of the inner container. The rim of the valve base is rolled over the rims of the inner and outer containers to connect the parts together. A sealing edge is defined on the rim of the outer container and on the rim of the valve base and thus the inner container is engaged with sealing line contact on both sides thereof. A sealing composition is also described as confined between the rims of the inner and outer containers. -1-
