Abstract
A dispensing receptacle has an internal chamber in which a piston is accommodated and separates the chamber into two compartments. The material to be dispensed is accommodated in one of the compartments which communicates with the exterior of the receptacle via a dispensing arrangement. A container with pressurized medium is accommodated in the other compartment and has a valve which, when actuated, releases a predetermined quantity of the pressurized medium into the other compartment so as to act on the piston and displace the same toward the dispensing arrangement with a concomitant dispensing of the material. An actuating arrangement is provided for actuating the valve of the pressurized medium container. A foil originally separates the one compartment from the dispensing arrangement, and the dispensing arrangement is provided with a cutting projection which perforates the foil so as to establish communication between the one compartment and the dispensing arrangement. The dispensing arrangement includes a tubular valve member which has a closed end facing the one compartment provided in its circumferential wall with at least one opening and the valve member is mounted in an outlet opening for movement longitudinally of the receptacle between a closed position and an open position in which communication is established between the one compartment and an exterior of the receptacle via the opening in the circumferential wall of the valve member. The pressure prevailing in the one compartment urges the valve member toward its closed position.
