Patent number: 6394364Abstract: A dual receptacle aerosol sprayer with a thin, flexible plastic outer receptacle for product and a substantially rigid inner receptacle for propellant seated within the outer receptacle. A closure closes the inner receptacle and contains a valve assembly. Primary propellant and secondary product valves in the valve assembly control flow from the inner and outer receptacles up propellant and product valve stem bores into an actuator having an aspirating nozzle insert with a Venturi constriction. A conduit extends from the valve assembly through the inner receptacle and into the outer receptacle. To avoid propellant overloading and rupture of the outer receptacle, a one-way tertiary valve downstream of the secondary product valve closes on clogging of the actuator discharge outlet to prevent, during actuation, misdirected propellant flow from the actuator and through the stem product bore and the secondary product valve, from entering the outer product-containing receptacle.Type: GrantFiled: September 29, 2000Date of Patent: May 28, 2002Inventor: Robert Henry Abplanalp

Patent number: 6016974Abstract: The present invention relates to a micropump for the nebulization of fluids with enhanced metering valve. The micropump comprises a hollow body and a set of stem and piston such as to constitute a "metering chamber" in the body. The hollow stem, which exits the body, is joined with a dispensing push-button fitted with a nebulization element. Pressing the dispensing push-button allows the passage of the fluid to be nebulized from the "metering chamber" to an exit duct, comprising the longitudinal cavity of the stem, a "compression pre-chamber" in the dispensing button and passages from the chamber to the nebulization element. The metering valve is obtained by interposing, in said fluid exit duct, an elastically deformable shutter.Type: GrantFiled: March 27, 1998Date of Patent: January 25, 2000Assignee: SAR S.p.A.Inventor: Francesco Mascitelli

Patent number: 5954273Abstract: A spray assembly for mixing catalyst with a high viscosity material and applying thin coatings of that material to a substrate that is particularly useful for applying body putty to a surface. The spray assembly has first and second through air passageways between an inlet end portion and different portions of an outlet end. The through air passageways each have a straight central axis adjacent the outlet end, the extensions of which axes outside the spray nozzle intersect a short distance from the outlet end of the spray nozzle. A large suction tube for the larger first air passageway has an upper end positioned within a cylindrical portion of the first air passageway. Air streams propelled through the passageways draw high viscosity material through the larger suction tube and catalyst through a smaller suction tube into those air streams. Intersection of those air streams outside of the nozzle mixes the catalyst material with the high viscosity material.Type: GrantFiled: April 22, 1997Date of Patent: September 21, 1999Assignee: Minnesota Mining and Manufacturing CompanyInventors: Constantin I.

Patent number: 5826795Abstract: A spray assembly including a venturi type spray nozzle, a valve attached to the spray nozzle, a reservoir adapter that can engage a reservoir containing a liquid coating material to be sprayed, and a flexible hose between tile reservoir adapter and the valve. The outer surface texture of material being coated can be adjusted using the valve which is useful in matching the surface texture of chip resistant coatings and undercoatings on an automobile, and the hose allows the operator to spray material onto a substrate from any orientation of the spray nozzle which facilitates coating locations such as the lower portions of panels or in wheel wells and trunks. A valve passageways is shaped to facilitate fine adjustment of the air/coating material ratio when small amounts of material are being delivered, and the valve includes an air purge to remove material from the valve and nozzle when the valve is shut off.Type: GrantFiled: August 19, 1996Date of Patent: October 27, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: Lowell W.

The air valve is biased in a closed position. A trigger is pivotally attached to the gun housing and engages the air valve. The trigger is also attached to one end of a spring biased pinch valve mounted in the housing. Another end of the pinch valve is biased against one end of a material disposable supply hose for pinching off the supply of material therethrough. An end of the disposable supply hose is attached to the housing and disposed adjacent an end of the air outlet port.Type: GrantFiled: May 30, 1995Date of Patent: September 16, 1997Assignee: Newstripe, Inc.Inventor: Ralph R.

Patent number: 5409166Abstract: A portable electric-powered particulate spreader has a housing having an inlet and an outlet. A reservoir for holding particulate material is located above the housing. A blower is located with a flow path extending from the inlet to the outlet for inducing air flow along the flow path. A particulate intake port is formed in a channel wall which encompasses an exhaust channel extending downstream from the blower to the outlet. A valve controls flow of particulate material from the reservoir to the particulate intake port. An agitator located between the reservoir and exhaust channel rotationally reciprocates and induces vibrations which assist the flow of particulate material. A foil in the exhaust channel produces a low static pressure in the which tends to draw particulate material from the reservoir into the air flow. Delays are built in so that the blower turns on before opening the valve is opened and the valve is closed before the blower is turned off.Type: GrantFiled: June 2, 1993Date of Patent: April 25, 1995Assignee: Natural Earth Technologies, Inc.Inventors: Rudolph M.

Patent number: 5096098Abstract: A problem which arises with dispensers for semi-liquid substances lies in there being an outlet channel which is permanently in communication with ambient air. After first use of the dispenser, the corresponding dead volume is filled with semi-liquid substance which quickly becomes spoiled; thereby making subsequent utilization at least difficult and possibly toxic or even impossible. The present invention avoids this difficulty by means of a pushbutton in which the outlet channel is defined by co-operation between a flexible part and a rigid part. The outlet channel extends essentially radially and its volume is reduced when the user applies axial pressure on the pushbutton. A motion transforming system for transforming axial displacement into radial displacement serves simultaneously to retract a plunger received in the outlet channel, thereby disengaging the delivery orifice of the pushbutton.Type: GrantFiled: October 31, 1990Date of Patent: March 17, 1992Assignee: ValoisInventor: Firmin Garcia

Patent number: 4850809Abstract: Apparatus for converting high pressure, low volume air to low pressure, high volume filtered air in order to successfully atomize fluids, such as paint, of various viscosities. The invention makes it possible to utilize safe, economical compressor air to atomize fluids by a portable enclosure including a variable jet venturi induction pump which separates the pump from the area of application and other potentially contaminating elements. Ambient air is introduced into the portable enclosure after regulation and filtration. A low pressure field is established in the induction pump by increasing the velocity of the compressor air in a venturi section of the pump but is free of contaminates generated, for example, by overspray in the vicinity of the area of application.Type: GrantFiled: April 14, 1988Date of Patent: July 25, 1989Inventor: William C.

Patent number: 4225085Abstract: Disclosed is a shower head dispenser for bath oil and the like which includes a body member with an axial bore adapted for insertion between a shower line and a shower head. The body member has two longitudinally spaced apertures or transverse bores in its side wall which communicate between the axial bore and a detachable oil container. It has a dam extending transversely across the bore. One of the apertures intercepts the axial bore at the crest of the dam, and the other aperture intercepts the axial bore upstream of the dam. The oil container has an integral valve stem thereon which seats in the end of the downstream transverse bore, and metering is achieved by rotation of the container. When water passes through the axial bore of the body member, the greater pressure at the upstream bore or aperture forces oil out of the container through the downstream bore or aperture into the axial bore at the dam, where it mixes with water enroute to the shower head.Type: GrantFiled: March 29, 1979Date of Patent: September 30, 1980Assignees: James J.
