ABSTRACT:
An apparatus for producing and spraying a mixture consisting of at least two components, e.g. liquids, and a propellant gas, comprising two nested containers for housing the components and the propellant gas and a discharge valve which is disposed at the outer container and has a small discharge tube operable from outside to establish fluid communication with the interior of the outer container. The inner container has a closure including a desired rupture site at its end remote from the discharge valve or facing the bottom of the outer container. The rupture site is adapted to be broken from outside by means of a crusher acting through the bottom of the outer container and establishing fluid communication between the inner and outer containers.
