Patent number: 5395032Abstract: A dispenser for dispensing a single dose of a powder medium is incorporated in an essentially hermetically sealed medium chamber with an essentially hermetically sealed compressed air pump. The pump chamber can be opened to the medium chamber through an inlet valve only after a first partial section of the pump stroke, whereupon the compressed air flow fluidizes the powder and expels it in a spurt to the dispenser outlet. A basic body forms an outer housing of elongated cross section with a freely accessible pump cylinder. The dispenser outlet can be easily gripped at the handles with which it is actuated.Type: GrantFiled: June 7, 1994Date of Patent: March 7, 1995Assignee: Ing. Erich Pfeiffer GmbH & Co.

Patent number: 5366122Abstract: In a discharge apparatus (1) on a basic body (8) is provided a pneumatic pump (19) and axially adjacent thereto a casing chamber (14) for receiving a magazine (15) for individual doses of a pulverulent or similar medium, whose magazine chamber (30) can be transferred into a discharge position, in which it is connected by one inlet end (46) and one outlet end (47) to a feed path (20) for the pumped air. At remote ends of the basic body (8) are provided pressure handles (5, 6) for the discharge actuation and a handle (7) for indexing or replacing a magazine body (16). Opening devices (50, 51) are used for the automatic opening of the magazine chamber (30) on transfer into the discharge position.

Patent number: 5350116Abstract: An actuator for a liquid spray pump is provided with a skirt which co-operates with a body of the pump to compress a volume of air during pump actuation. Air compressed by this action is ejected from an air injection channel in the vicinity of a liquid spray emerging from a first nozzle defined by the actuator. A second nozzle is connected to the actuator externally of the first nozzle to define an air gap therebetween and the air ejection channel communicates with the air gap such that in use both the liquid spray and the compressed air are dispensed through the second nozzle aperture. Primarily intended for dispensing water based products, the effect of the compressed air is to assist in the evaporation of water contained in the liquid or any other volatile liquid dissolved in a liquid product to be dispensed in aerosol form.Type: GrantFiled: March 1, 1993Date of Patent: September 27, 1994Assignee: Bespak PLCInventor: Miro S.

Patent number: 5341801Abstract: An inhaler for delivering metered doses of a particulate drug. The inhaler is formed of a housing, a drug reservoir attached to the housing to contain multiple doses of the particulate drug, a drug transporting slide in the housing that contains a metering chamber of volume corresponding to a desired dose of the drug, and a vacuum pump that creates a partial vacuum in the metering chamber. The drug transporting slide is movable from a load position, in which it communicates with the drug reservoir to receive in its metering chamber drug from the drug reservoir, to a release position in which it communicates with an air outlet passage to release drug from the metering chamber into the air outlet passage. The drug reservoir has an air permeable portion that permits air flow into the drug reservoir but prevents drug escape. In use, the vacuum pump draws a dose of drug into the metering chamber. The drug transporting slide then moves to deposit the drug in the outlet passage for inhalation.Type: GrantFiled: November 30, 1992Date of Patent: August 30, 1994Assignee: Sandoz Ltd.Inventor: Kurt Zechner

Patent number: 5328099Abstract: A compressed gas device is disclosed for spraying a single dose of a fluid substance in finely divided form. The device comprises a tank containing the single dose having an inlet orifice for compressed gas, and an outlet orifice. The device further comprises a manually actuated gas pump having a gas supply communicating with the inlet orifice of the tank via an intermediate channel. The intermediate channel has a length of narrowed section that is closed in a sealed manner by a plug which is held in the narrowed section so that when the pressure of the gas supplied by the pump reaches a predetermined threshold, the plug is expelled towards the tank to open the intermediate channel. The device includes an abutment element to limit the displacement of the plug towards the outlet orifice of the tank of substance. The abutment element is constructed to guarantee that the compressed air can continue to floe through the outlet orifice when the plug is in its abutment position.Type: GrantFiled: June 16, 1993Date of Patent: July 12, 1994Assignee: Etablissements ValoisInventors: Ludovic Petit, Philippe Solignac, Pascal Bruna

Patent number: 5322101Abstract: The manually-operated balloon stuffing device has a minimum number of parts and is inexpensive to manufacture. The device includes a manual pump consisting of inner and outer cylindrical tubes, and a check valve in each tube that permits the passage of air in only a single direction within its respective tube. In a first embodiment, a balloon stuffing item is placed in an end of the inner tube, and the open balloon end is stretched over that tube end. The outer tube is then reciprocated along the longitudinal axis of the inner tube to pump up the balloon. The outer tube is then removed and a push rod pushes the sliding check valve, which in turn pushes the stuffing item into the inflated balloon. In an alternate embodiment, a large hollow adapter tube is placed on the end of the inner tube, and the open end of the balloon is stretched over the open end of the adapter tube.Type: GrantFiled: June 16, 1993Date of Patent: June 21, 1994Inventors: Mark J.

Patent number: 4884600Abstract: An oil nozzle allows for oil to be poured into an engine without the spillage and waste commonly accompanying oil pouring from conventional threaded containers. By use of the tightening member a threaded oil container is attached to the oil nozzle in its closed position and positioned on top of an oil receiving port of an engine. The oil container is pushed downward which opens the oil nozzle and allows oil flow from the container into the oil port. After a desired amount of oil has been dispensed, downward pressure is applied to the shut-off handle which seals the nozzle in its closed position.Type: GrantFiled: November 21, 1988Date of Patent: December 5, 1989Inventor: Ronald J.
