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.

A dispensing receptacle comprising an elongated substantially cylindrical housing having a closed end and a dispensing end longitudinally spaced from said closed end, and provided with a chamber; valve means connected to said dispensing end of said housing and operative for establishing communication between said chamber and the exterior of said housing; a piston mounted in said chamber for displacement longitudinally of said housing and sealingly subdividing said chamber into a first compartment containing the material to be dispeNsed, and a second compartment; a substantially cylindrical container for a pressurized medium situated in said second compartment and connected to said housing coaxially therewith in the reginon of said closed end thereof, and having a valve formed with an actuating element; and actuating means including an elastically yieldable hollow projection extending centrally and exteriorly of said closed end, said actuating element of said valve of said container extending into said hollow projection and cooperating therewith so as to open said valve when said hollow projection is elastically deformed to thereby release a predetermined quantity of the pressurized medium into said second compartment for displacing said piston toward said valve means with attendant dispensing of said material through the latter.
