Abstract: An inhaler for powder products comprising a housing having an oral suction mouthpiece, a piston contained within the housing for movement in opposite directions, and an elastic member for urging the piston in one direction. The mouthpiece connects with a chamber in which the piston is located so that inhaling through the mouthpiece draws the piston toward the user's mouth. The piston includes a charging cavity for holding a charge of powder product. The cavity communicates with the internal volume of the mouthpiece as the piston is drawn toward the user's mouth whereby the charge is dispensed and inhaled by the user.

Abstract: A liquid dispensing device having a pump carrying the internal mechanism disposed in a container part of the device. The pump has a flange which rests on the upper edge of the container and which is connected to an outer bush member. The bush member is fitted on an outer bearing surface of the wall of the container in radial sealing engagement therewith. The pump includes a venting passageway for connecting the interior of the container to the atmosphere during dispensing of the liquid. In assembling the device, the pump and bush member are first connected together and then connected to the container with the pump in a position to maintain the passageway open to the interior of the container.

Abstract: An apparatus for storing and combining at least two discreetly stored chemical compositions to form a mixture or a reaction product and to dispense the mixture or reaction product therefrom. The apparatus comprises at least a first receptacle and a second receptacle, each configured for operation with a corresponding aerosol valve and a connecting bridge member configured for operative gas-tight association with each aerosol valve. The first receptacle contains a first component, stored therein under a substantially positive internal pressure, which is permitted to flow along a path extending through the bridge member into the second receptacle wherein it is mixed or reacted with the second component and subsequently sprayed through a spray nozzle located at an end of the bridge member.

Abstract: The invention relates to a dispensing valve comprising a body formed of a cylindrical casing of rigid material closed by a cover, in which two seals having fluid-tight joints create a lock chamber inside which moves an atomizer provided with a sliding distributor, guided at its ends, which a return spring placed upstream urges towards the cover. The valve has a sleeve allowing alteration of the volume of the chamber and a front seal formed as a separate member, both formed of semi-rigid plastic material. The seal is disposed immediately adjacent an abutment surface formed in the casing. The design is such that entry of liquid during filling takes place through an auxiliary duct and the front seal and sleeve may be formed as a single member if desired.
