Patent number: 5482175Abstract: A pressurized container end has a frangible member covering an opening in the end. The frangible member is cut away from the end by the action of increased pressure from within the container against the member. A protrusion in a portion of the end is depressed into the container for increasing pressure in the container. In an alternate form of the invention, the container itself is depressed inwardly for causing the increased pressure sufficient to cut the frangible member away from the end. Various opening geometries are each formed with a cutting edge.Type: GrantFiled: December 28, 1993Date of Patent: January 9, 1996Inventor: Naseem B. Arrar

Patent number: 5012956Abstract: A fluid dispenser system being a substantially conventional squeeze bottle within which a collapsible flaccid bag, containing dispensable fluid, is suspended. The bag is spaced from interior surfaces of the bottle and a pressure actuated valve, that facilitates fluid discharge and blocks against back flow entry of air into the bag, closes the bag. The bottle is vented, having a vent hole which is normally open, permitting air entry into the space between the interior surfaces of the bottle and the exterior surfaces of the bag. This vent hole requires obturation incidental with squeezing of the bottle, for fluid dispensing. In that situation air is trapped in the space and compressed, and indirectly exerts outwards pressure against the valve causing the valve to open, and promotes dispensing of the fluid whereby the bag progressively collapses as fluid is expelled.Type: GrantFiled: August 7, 1989Date of Patent: May 7, 1991Inventor: William R. Stoody

Patent number: 4903862Abstract: A soft drink dispenser capable of rapidly dispensing carbonated beverages with minimized foaming action. The syrup and soda are dispensed separate from each other and allowed to mix upon the ice in a cup placed beneath the dispensing head. The dispensing of the syrup and soda is staged to minimize foaming while achieving optimum beverage taste. Syrup is dispensed from individual pumps which communicate with a bulk supply. The syrup is consolidated in the pumps, preventing waste or the introduction of "slugs" into the dispensing line. The temperature of the syrup is monitored and compensation is made during the dispensing cycle to accommodate changes in viscosity. In generating soda, water is precooled and then introduced into an insulated tank where it is subjected to pressurized carbon dioxide. In the pour head, a cluster of soda orifices are peripherally encompassed by syrup orifices, certain of which are angled to cause the syrup to convolute the stream of soda.Type: GrantFiled: October 13, 1987Date of Patent: February 27, 1990Assignee: ABC/Sebrn Tech.
