Patent number: 7185781Abstract: The “HOT DRINK CUP LID WITH COOLING AIR-FLOW” is an article of manufacture with a uniquely designed form arranged so that the hot liquid is cooled by an air-flow drawn over the liquid as it is sipped. The unique design, placement of the drinking hole and cooling air-flow hole create a structure whereby hot liquid can be cooled and sipped in a manner that reduces the temperature of the hot liquid as it transfers from the cup to the user. This cooling action is activated by the suction caused by the action of the user sipping at the drinking hole and concurrently drawing air from outside of the cup down through the air-flow hole and up through the drinking hole along with the hot liquid. Thus the hot liquid is cooled as the air is drawn up in conjunction with the hot liquid through the drinking hole.Type: GrantFiled: March 16, 2004Date of Patent: March 6, 2007Inventor: Constance Linda Pitts

Patent number: 7159731Abstract: A filter pump cover according to the invention comprises a filter cap, an air purge valve, and a filter cap retainer. An air purge valve according to the invention is comprised of a valve cap, a screw-threaded portion, and a valve stem having one or more outward-facing inverse hooks at the bottom. The inverse hooks are located at the bottom of the air purge valve stem and hook onto the bottom lip of the hollow central portion of the filter cap retainer to prevent complete removal of the valve stem from the filter cap retainer. The valve screw-threaded portion is interrupted by a valve opening slot on one side that permits the release of air from the pump when the valve is opened. The hollow part of the filter cap retainer mates with and holds the air purge valve by means of the screw threads when the valve is closed.Type: GrantFiled: March 3, 2004Date of Patent: January 9, 2007Assignee: Bestway Inflatables & Material Corp.Inventor: Yao Kai

Patent number: 6669047Abstract: A pressure cooker handle assembly that relieves pressure in the cooker and unlocks the lid by pushing a single button twice. The button includes a tab that directly activates a pressure relief valve to release the pressure and a leg that depresses a stopbar to unlock the lid. Pressing of the button a first time releases the pressure in the cooker, but does not unlock the lid. A latch system prevents the cooker from again building pressure once the button is pressed. When the button is pressed a second time the leg depresses the stopbar to unlock the lid from the cooker.Type: GrantFiled: December 21, 2001Date of Patent: December 30, 2003Assignee: Innovation IP Holding CoInventors: Blaise M.

Patent number: 6644489Abstract: A container assembly includes a cover cap mounted detachably and sealingly on a container. The cover cap has a pump-mounting wall portion defining a pump-receiving chamber, an inlet formed in the pump-mounting wall portion and in fluid communication with the pump-receiving chamber and a storing space of the container, and a valve-mounting wall portion defining an opening which is in fluid communication with the storing space and the atmosphere. A pump member is disposed movably and sealingly in the pump-receiving chamber, and has an outlet in fluid communication with the pump-receiving chamber and the atmosphere. An urging member urges the pump member away from the inlet. First and second check valves are respectively mounted on the cover cap and the pump member for closing the inlet and the outlet of the pump-receiving chamber, respectively. An air-inlet valve is mounted on the pump member for closing the opening in the cover cap, and is operable to uncover the opening in the cover cap.Type: GrantFiled: March 27, 2002Date of Patent: November 11, 2003Inventor: Tai-In Chang

Publication number: 20030183631Abstract: The package is closed by a lid and it is fitted with a valve fixed over an opening zone of section greater than 10 mm2, and preferably lying in the range 30 mm2 to 50 mm2, leading to the inside of the package and formed through said lid. This opening zone is either an orifice formed through a flat lid, or else a hollow chamber itself pierced by a vent orifice of small size. The valve comprises solely a flexible sheet extending over the opening zone together with a sealing compound disposed between the flexible sheet and the lid. The sealing compound is solid at ambient temperature and it passes to a non-sticky liquid state when its temperature is raised. During heat treatment, the valve opens and closes in a succession of venting sequences.Type: ApplicationFiled: March 27, 2003Publication date: October 2, 2003Applicant: PROPLASTInventors: Anthony Bernard Cross, Didier Guitton
