Abstract: Dispenser has a nozzle with a tip seal valve and an internal check valve defining a discharge chamber between them. The tip seal valve actuator extends along the squeeze bottle side so that it can be actuated at the same time as the bottle is squeezed. Because of the check valve, there is no "suck back" as bottle is released. A bottle vent permits air in, but does not allow liquid to escape.

Abstract: A hollow body has a connected tubular discharge stem. The stem has a tapered tip formed with at least one discharge passage. An annular gasket complementing the shape of the taper is normally seated on the tip and valves off the passage. A hollow tubular shell is over the stem and carries the gasket at its upper end. The shell encloses a spring working between the bottom of the shell and a fin on the stem spaced back from the tip. In operation, the shell is moved away from the body so liquid can discharge through the gasket.

Abstract: A dispensing package adapted for delivering medicine to a nasal cavity for absorption into the bloodstream comprises a flexible-walled container having a discharge head with a swirl chamber and a dip tube depending therefrom into the container. In use, the container is squeezed to drive liquid up the dip tube and into the swirl chamber to be discharged upwardly into the nasal cavity in the form of a fountain of relatively large droplets. The swirl chamber operates in the absence of air.

Abstract: Dispensing apparatus (10) for use in a pressurized dispensing container (12) comprises a valve (18) mounted in a cup member (11) and an elastomeric vessel (13) forming a collapsible chamber (23). The vessel (13) is attached to the mounting and depends from the cup cylindrically surrounding the valve body (18). The vessel is attached to the cup member by having a flange (14) which is thermally bonded to the thermoplastic layer (5) covering the internal surface of the cup member. The flange (14) includes grooves (9) which prevent contamination from sputtering during thermal bonding. The apparatus has application for medical products including edible foam dispensed from containers having an internal fill pressure.

Abstract: A reclosable valve stem actuated valve structure for aerosol-type containers and the like is provided which has an external seal that includes a seal member, a bonding agent, and a separatable frangible zone. The external seal is installed after the valve structure is associated with a container and after a container filling operation of the type where filling is accomplished through the valve structure.

Abstract: A reclosable valve stem actuated valve structure for aerosol-type containers and the like which valve structure is provided with a preassembled but removable external seal. The seal includes a seal member, bonding agent, and a rupturable frangible zone. The valve structure can be associated with an aerosol-type container without interference from the seal and the seal can be opened before the interveningly filled valve-equipped container is used.

Abstract: A stem tiltable valve structure for aerosol containers and the like wherein a moveable cup member is provided which is actuated by stem tilting and which when so actuated undergoes reciprocal sliding movements in the valve structure. In the closed position, a positive sealing action is achieved between the moveable cup member and a gasket. The valve structure is well adapted for the dispensing of a highly viscous liquid.

Abstract: A reclosable moveable valve stem actuated valve structure for an aerosol-type viscous fluid dispensing container. The valve structure is provided with an initially sealed internal seal and a valve stem operated internal seal removing component. The valve structure is preassembled before association with the container. The seal includes a seal plate and releasable bond. The seal removing component is associated with a moveable valve member. The moveable valve member is operated initially by movement of the moveable valve stem and causes the internal seal removing component to effectuate a release of the releasable bond, thereby opening the initially sealed internal seal.

Abstract: A fluid dispensing valve structure for dispensing the viscous contents of a pressurized container. The structure incorporates a tiltable elongated tubular nozzle which, when tilted, longitudinally moves a moveable cup member in a valve chamber, away from a seal, thereby opening the valve. Fluid from the container passes transversely through a side opening in the valve chamber over a top region of the moveable cup member and into the nozzle during dispensing.

Abstract: A tilting nozzle valve assembly incorporating a nozzle actuated moveable cup member. The valve assembly has a high flow capability for passing highly viscous fluids therethrough. The moveable cup member provides a positive valve sealing action between itself and a gasket in the valve assembly. The moveable cup member features a camming member which provides both an accelerated valve opening action responsive to nozzle tilting and also a maximizable opening between the moveable cup member and the gasket.

Abstract: An aerosol valve for pressurized containers having a tip seal to seal the dispensing nozzle at its extreme outer end portion and having a base seal in which each seal is operated simultaneously by tiltable deflection of the nozzle to dispense the contents of the aerosol container. Another embodiment of the invention sequentially opens the tip seal followed by opening of the base seal.

Abstract: A tilt valve structure for pressurized containers having a base seal which is operated by tiltable deflection of the nozzle to dispense the contents of the aerosol container. The valve structure incorporates a deformable bridge stop structure which retains the structure in a closed but assembled configuration after valve manufacture until usage, including assembly of valve onto a pressurizable container. The bridge stop structure can assume two positions: an initial position and a second valve operating position. The bridge stop structure can be formed of inelastic or elastic material, such as metal.

Abstract: A trigger-like actuating element for association with a pump having a depressable piston or plunger for dispensing small metered quantities of a liquid from a container such as a jar, bottle or can, the trigger-like element being designed to be manually operated for substantially horizontal movement to thereby depress vertically the pump piston or plunger in order to deliver a quantity of liquid, usually as a spray, in a horizontal direction.

Abstract: Cleaning and scrubbing tool having a cleaning head and aerosol can handle in which a suitably operational scrub pad is supported by head bracket extension in free cleaning liquid passing relation, interlocked with portions of the pad by localized deflection of the extension, suitably by locally heating or solvating the extension to deflectable condition within the pad interior.

Abstract: A pump for dispensing small metered quantities of a liquid from a container such as a jar or can, the pump including a housing and a plunger, in combination with a valve comprising an annular washer having a rectangular cross-section, assembled between the pump housing and the plunger to provide tight seals throughout a plurality of annular surfaces, in order to prevent leakage in the closed position, and to tilt axially on the pumping stroke to permit escape of the liquid being pumped. Automatically opening container venting means is also provided.
