Abstract: A fluid flow control valve for use in a fluid applicator tip which is connectable onto an open end of a resiliently squeezable bottle. The valve includes a valve body defining a flow aperture formed centrally therethrough. A separate sealing ball is held in coaxial alignment and spring biased seated retention against the flow aperture and oriented downstream of fluid flow through the flow aperture from the open end of the container. The valve is thus normally closed and opens or unseats automatically to permit fluid to flow through the fluid aperture when the bottle is held in at lease a somewhat inverted orientation and squeezed to increase fluid pressure against the spring biased sealing ball. The sealing ball automatically reseats when there is no substantial pressure within the bottle, preventing virtually all fluid flow and leakage.

Abstract: A unitary over-molded non-clogging system having mechanical breakup capability, a positive shutoff flared wall skirt, having two different overmolded materials forming a laminate combination. The soft flexible face inner portion with a flexible positive shutoff in combination, with mating sealing surface points at two distinct positions, on a conventional actuator body post, forms half of the unitary fitment. A hard portion contour forms the outer half, maintaining registration and retention of the entire overmold fitment within the actuator. This overmold combination fit provides these features without increasing the total amount of parts normally used in conventional spray actuators on pumps and aerosol systems. The actuator can employ a post with or without a mechanical breakup face while the mating surface of the inner soft interfacing portion would compliment it. This type of actuator also can be used as an outlet valve means for pumps, reducing overall cost.

Abstract: A nozzle for dispensing a product while perserving the sterility of the product remaining in storage incorporates a mechanism which combines a flexible static seal and a valve. The valve moves as the static seal is deflected to open an orifice allowing the stored product to be expelled into the air. The seal is deflected sufficiently to open the valve only when the pressure behind the seal is great enough to force flow from the product container to the atmosphere. If the pressure in the sterile container is lower than the ambient pressure, which would permit a flow of air and microbiological contaminants into the container, then the static seal, with the help of a spring, is deflected to force the valve to close.
