Abstract: A one piece self closing dispensing valve of molded polymer material is used in combination with a beverage container. The valve is of the kind containing a movable actuator which in response to a force applied thereto by a user, such as pressure exerted by the users finger, opens the valve to dispense liquid under force of gravity. A leaf spring operable over the range of actuator movement and normally biasing the actuator responds to the withdrawl of the applied force to return the actuator to its normal position and thereby close the valve. An integral dripless spout is defined between the actuator and the valve body; the effective size of which is inversly dependent on the position of the actuator.

The opposite wall is spaced from confronting end sections of the partition walls by another length.

Abstract: A dosing device for dispensing liquid from a container comprises an outlet passage for the liquid and an obturator, such as a flap or piston, that is adapted to be driven to block the outlet passage, once a quantity of liquid has been dispensed, under the influence of liquid flowing from the container through a small aperture into a space behind the obturator in a chamber in which the obturator is movable. The outlet passage has a convoluted configuration whereby flow of liquid through it is directed at least partly back towards the obturator to exert a back-pressure thereon, the obturator being of a dimension such that it may be acted on by liquid in part of the passage in which the flow is thus directed back. The chamber may have a moveable wall portion that opens up a large aperture to allow rapid restoration of the obturator to its start position.

A guideway in the snout slidably accepts a rod on the upper end of which is a valve. Encircling the lower end portion of the rod is a ring so sized as to be seatable against the top wall of the cap. A plurality of resilient webs are circumferentially distributed in a normal plane and integrally extend between the ring and the rod with each of those webs generally defining a partial spiral and the webs together enabling longitudinal movement of the rod when the ring is seated against the top wall of the cap.

Abstract: A drain valve assembly is mounted in the bottom of a fuel tank (10) to allow draining of condensate. The tank (10) is drained of fluid by the use of a tool (27) pushed upward against the piston (18) of the valve assembly separating it from its seat (15) in the valve housing (12) allowing liquid which has entered the housing (12) from the tank (10) through openings (16 ) to exit around the periphery of the unseated valve. If the valve assembly base is struck by lightning, a blast pressure occurs that can drive the poppet of a standard valve open allowing the electrical energy to enter the tank (10) causing a potential explosion. With the present valve assembly the pressure is allowed to pass through passage (20) in the piston (18) to apply a closing force on the surfaces (21, 22) and the inner end of the piston (18) which is greater than the opening force due to the area difference and the valve assembly remains closed.

In an alternative version, a ball valve is so seated as to preclude wedging of the material into the valve seat.

Abstract: Apparatus for controllably transferring fluid from a pierceable pressurized container includes a valve body, a stem member which is threadably connected to the valve body at one end and a fluid-conducting hose at the other end, and an elastomeric valve ball disposed in a cavity between the body and the stem member. The valve ball controls fluid flow from the container through the valve body and stem member to the hose in response to rotation of the valve stem relative to the body. Simultaneously, the valve balls acts as a check valve to prevent flow of fluid to the container. An O-ring seal between the stem and the valve body is adapted to leak at high pressure and bleed off fluid.

Abstract: The glue dispenser comprises a collapsible tube having an externally threaded spout. A nozzle assembly comprises an internal nozzle threaded onto the spout and a external nozzle mounted on the internal nozzle. A nozzle valve registers with the opening of the external nozzle and is biased into closing engagement therewith by a deformable portion of the valve being urged against a cam surface. A piercing element is formed on the internal nozzle element, and when the nozzle is completely threaded down on the threads of the spout of the collapsible tube, the piercing element penetrates the sealing diaphragm of the spout so that the material in the collapsible tube can be squeezed through the spout and through the nozzle, with the nozzle valve controlling the flow of the material from the dispenser.

Abstract: A drink dispenser spigot comprises a barrel, a valve plunger, a stem for the plunger, and a spout opening in the barrel. A splash deflector collar about the stem is movable therewith. As the spigot is opened by withdrawing the plunger so that it passes over the spout opening to dispense drink, the splash deflector at least partially blocks splashing of the drink through the spout opening and into the barrel. Some drink splash may enter the barrel but the splash deflector has a wiper flange which will wipe interior surfaces of the barrel as the plunger moves toward closed position and wipe drink splash from the inside of the barrel and out through the spout opening.

Abstract: A housing containing annular tapered valve seat and mating valve secure the valve in fluid communication with the container interior. Fluid in the container under pressure displaces the valve from its seat, flows through the interface between the valve and seat and is discharged to the ambient through a fluid passage coupled to the interface. A shoulder in the housing engages a shoulder on the valve for limiting the displacement of the valve to a value sufficiently small to retain fluid in the interface in the absence of pressure above ambient in the container. The fluid in the interface acts effectively as a seal to ambient air so that a negative pressure in the container results in ambient air pressure forcing the valve to its closed position.
