Abstract: My invention is a mixer and dispenser having a dispensing top with an outflow channel, an air vent, and an air vent valve that adjusts the vacuum inside the dispenser; a rotor attached to a battery powered motor; and two switches, one for operating automatically upon pouring and the other manually activated. The vacuum system controls the flow rate during pouring and the constant mixing disperses the ingredients so that the samples dispensed are representative of the original mixture.

Abstract: A fluid applicator includes a coating implement, an elastic closure cap, and a stopper for use with a fluid container. The elastic closure cap includes an enlarged irregular sealing rib on a skirt that is force-fit into the stopper, creating a resilient force on a sealing lip that contacts a seat on the stopper. Inverting the container and pressing on the coating implement, presses the elastic closure cap, deforming it to move the sealing lip off of its seat on the stopper to allow fluid flow from the container, through the stopper and elastic closure cap, to the coating implement.

Abstract: The invention includes aseptic packages and methods and systems allowing aseptic filling on a conventional filling line, with relatively small and inexpensive equipment modifications.

Abstract: A valve for preventing the flow of fluid when the temperature of the fluid is above a predetermined threshold, the valve including: a body having at least one opening for allowing the fluid to pass when the temperature of the fluid is below the predetermined threshold; and a shape memory or bi-metal actuator for substantially closing the at least one opening when the temperature of the fluid is above the predetermined threshold to prevent the fluid from passing.

Abstract: A sports bottle cap having a pressure differential valve is provided which allows water to flow out through the bottle cap only when the bottle is inverted and squeezed or alternatively a straw may be threaded through the pressure differential valve, thereby deactivating it, and attached to the bottle cap allowing the user to draw liquid from the bottle through the straw. In operation the bottle cap of the present invention allows the user to dispense fluid from within the bottle in two different ways. The first manner of use allows liquid to be dispensed only when the bottle containing the liquid is inverted and squeezed. Squeezing causes the pressure to increase on the inside of the bottle thereby causing the pressure differential valve to open and liquid to exit; however, when the bottle is not squeezed the pressure differential valve remains in the closed position sealing bottle.

A sealing lip 15 is formed on the stopper collar 11 and can seat in a sealing fashion on a container edge 25 surrounding the container opening. The stopper collar 12 has a control channel section 29 transverse to the control channel 16 of a stopper member 11 which extends this control channel 16 up to the sealing lip 15. A reliable venting is guaranteed while simultaneously securing sealing to prevent the escape of battery liquids. Economical production with large yield is also facilitated.

Abstract: A vacuum apparatus for easily forming a vacuum in any bottle, container or the like and for providing a stable sealing. A lower cylindrical member together with a disc member forms a space portion in which a vacuum or an atmospheric pressure is applied, and the lower portion of an upper cylindrical member is inserted in the space portion and divides the space portion into upper and lower spaces. With a downward movement of the upper cylindrical member, the upper space expands and draws air inside of a bottle, and with an upward movement thereof, the air introduced into the upper space is vented outside. At this time, a check valve is selectively opened and closed and is operated by a pressure difference applied thereon. By repetitive reciprocating movement of the upper cylindrical member, a high vacuum is formed in the bottle and is sealed by the check valve. The apparatus is adaptable in a vacuum bottle, a medical suction instrument or the like.

Abstract: This device has three main components: a storage container, an air-tight lid and a pump for extracting air. The storage container is distinguished by a ring-shaped protrusion in the concave bottom of the container. This protruding ring is designed to fit tightly into a concave ring on the lid of another container of the same design. This feature enables the containers to be stacked conveniently on top of one another. The storage container is further distinguished by an elevated lip on the upper rim of the container, which forms an air-tight seal with the lid. The lid is distinguished by a vacuum valve containing two layers with several holes in each layer. The vacuum valve contains an umbrella-shaped silicon piece, which can bend upwards to allow air to be drawn out by the pump, but is restricted from bending downwards (which would allow air to enter the container).

Abstract: A plug device for a liquid container is presented to enable cleaning of a flow passage of the liquid container as well as to eliminate the liquid being left in the flow passage during the operation of the liquid container, thus providing hygienic and safe operation of the container. The plug device consists of an outer plug member and an inner plug member which is detachably attached to the outer plug member. When the members are assembled, a flow passage is formed automatically to enable access to the liquid stored in the container. When a press button provided on the inner plug member is pressed down, the opening disposed at the bottom of a plunger device remains open, resulting in the interior space of the container being connected with the flow passage via the internal liquid passage. In this condition, the container can be tilted to dispense the liquid from the container.
