Abstract: An apparatus and method for removing a lodged mass from an airway of a human or animal in which the source of suction is a sealed vacuum container which is punctured when the device is positioned within the mouth of the victim. As contrasted with prior art devices of this type, the retracting force created due to the pressure differential is developed instantaneously to a greater degree than heretofore obtainable, and this force is maintained until the foreign object is completely dislodged.

Abstract: An aerosol tilt valve has an integrated molded hollow stem shaft and molded conical stem cup. An upper outer circumferential edge of the stem cup normally fully seals, except when the valve is tilted, against a gasket surrounding the stem shaft. The outer lower wall of the stem shaft and the inner wall of the stem cup define an annular space. At least one molded metering orifice below the upper edge of the stem cup extends from the annular space through the stem shaft. The stem shaft is molded with a molded annular recess about the lower shaft end and with the at least one molded metering orifice. The molded stem shaft is inserted in a mold cavity. A lower portion of an annular shield blocks the metering orifice, and together with the mold cavity and lower part of the stem shaft, defines the stem cup shape. The stem cup is molded having an annular projection extending into the annular recess to form a strong and fully integrated stem cup and stem shaft functioning essentially as one piece.

Abstract: A dispenser comprising a valved aerosol container and a unitary flexible barrier member having a wall portion terminating in sealing means, which sealing means is joined to the container in either a top seal or bottom seal relationship. The wall portion has first and second wall portions, the first wall portion terminating in a central piston region and the second wall portion terminating in a sealing flange, the wall portion being steeply frusto-conical and sufficiently thick and rigid to be free-standing before incorporation into a container. The barrier is nestable with like barriers.

Abstract: In an aerosol valve comprising a mounting cup, a gasket having a central opening, a valve housing, a valve stem and a valve body, where the valve stem and valve body move within the valve housing in response to pressure on the valve stem, the valve body having a cylindrical upstanding wall defining a recess. A slot extending through the wall is defined by the wall and a thin skin. The slot communicates with the interior of the container when the valve is actuated. A swirl chamber may be located at the bottom of the valve body. The valve can be configured for tilt actuation.

Abstract: Broadly stated, this invention comprises a pressure container having an extruded plastic body portion and plastic end closures for the body portion, each end closure having a recess portion for receiving the respective ends of the body portion. In a preferred embodiment one of the closures is adapted to receive a conventional aerosol valve having a mounting cup for clinching onto the said closure. In a still further preferred embodiment, the non-valved closure has a port for bottom gassing of the container when the product to be discharged and the propellant are separated by a piston.

Abstract: An aerosol actuating cap is disclosed for use with an aerosol container having a tilt valve. An actuator is mounted on the cap by a pair of torsion hinges. The axis of the hinges is positioned directly above the valve stem such that axis of rotation of the actuator intersects the axis of the valve stem. Upon depressing the rear of the actuator, the actuator rotates about the hinge axis. Consequently, an engagement surface contacts and displaces the valve stem and, thereby, actuates the valve. A product flue is positioned at the front of the actuator which flue is rotated with the actuator such that, on actuating the valve, the product stream from the valve stem proceeds through the flue.

Abstract: Apparatus and method for applying gasket material to the skirt of a gasket for the mounting cup of an aerosol container, wherein the gasket material is mechanically applied to the mounting cup through the use of a novel mandrel and cutting arrangement. A mounting cup, having a uniquely placed gasket, the gasket extending from the skirt into the channel of the mounting cup.

Abstract: In an aerosol valve comprising a mounting cup, a gasket having a central opening, a valve housing, a valve stem and a valve body, where the valve stem and valve body move within the valve housing in response to pressure on the valve stem, the valve body has at least one upstanding wall defining a recess. A slot extending from the top shoulder of the upstanding wall communicates with the interior of the container when the valve is actuated. The valve stem has an orifice aligned with the longitudinal opening of the valve stem which communicates at one end with the slot in the recess of the valve body and at the other end with the orifice in the valve stem. The central opening of the gasket seals the slot defined by the upstanding wall of the valve body when the valve is in a closed position. The valve body also has a shoulder with an annular recess at the base of the upstanding wall.

Abstract: An aerosol spray dispenser system for use with a container having both product and propellant under pressure and in vapor and liquid phases, including a valve unit in which there are separate product and propellant passages, preferably valved by a single gasket, leading from the container to an impact mixing chamber disposed within the valve unit. Here streams of liquid and propellant impact one another to form a fine dispersion of vapor in liquid which is then discharged. Preferably a venturi constriction is disposed in one of the passages just upstream of the mixing chamber. In certain embodiments the chamber and venturi are disposed in the valve housing or in the valve stem; in others they are disposed in the valve actuator contiguous to the discharge orifice; and in still other embodiments they or either of them may be in both locations.
