ABSTRACT:
A container filled only partially with a pre-measured, exactly apportioned quantity of liquid active ingredient for one-time use closed in a pressure-tight manner by a closure made at least in part of a resilient material having self-resealing characteristics after piercing with a needle, and a reservoir filled with an aerosol propellant of a type incompatible with said active ingredient after a relatively short time when intermixed. The reservoir has a discharge valve with a hollow needle pushed through the resilient material of the closure and held by the material in a fluid-tight manner, whereby the container can be filled with the propellant only shortly before use of the active ingredient.
