The neck structure defines a neck opening with a cylindrical sealing surface surrounding the neck opening and an external neck surface. The closure comprises a cap formed of resilient material having a top and a downwardly extending skirt portion depending from the top. An annular plug depends from an underside of the top and one or more ribs are formed on an internal surface of the downwardly extending skirt portion. The annular plug and the one or more ribs are arranged concentrically and are dimensioned such that, upon application of the cap to the neck structure, the annular plug projects into the neck opening and engages the cylindrical sealing surface. At the same time the one or more ribs engage the external neck surface.Type: ApplicationFiled: January 7, 2003Publication date: September 18, 2003Inventor: Gerry Mavin

Publication number: 20020066714Abstract: A vented closure, for preventing deformation of a container containing a gas evolving liquid, is provided. The closure includes a first closure member and a second closure member. The first closure member seals the container from the outside atmosphere and defines a gas inlet, a gas outlet and a gas flow passage between the inlet and the outlet. A gas-permeable, liquid-impermeable membrane is placed in the gas flow passage. The second closure member is moveably fitted on the first closure member and encases the first closure member with a small clearance fit that allows gas passage. A sealing element coupled to the second closure member is aligned with the gas outlet of the first member so as to block gas flow when a predetermined load is applied to the second closure member and allow gas flow when the predetermined load is absent.Type: ApplicationFiled: April 11, 2001Publication date: June 6, 2002Inventors: W.K. Mainquist, John F. Breznock

Patent number: 6364152Abstract: A food storage container 10 includes a base 12 and lid 14. The base 12 has a sealing flange 22, and the lid 14 has a sealing lip 32 which seals against the sealing flange 22 as with a suction cup. The lid 14 may include resilient deformable sections 46, 50, to aid in maintaining reduced pressure within the container. The lid 14 may include latch prongs 54 to mechanically retain the lid 14 in position. The latch prongs 54 may be designed to automatically release during heating of the food, permitting venting. The sealing lip 32 may include seal spacers 60 which permit air to enter the food storage container 10 during serving of hot food to avoid creation of reduced pressure in the container. The seal spacers 60 do not interfere with normal creation of a seal when desired.Type: GrantFiled: April 12, 2000Date of Patent: April 2, 2002Assignee: Dart Industries Inc.Inventors: Edward M. Poslinski, Brent E. D'Alessio

Patent number: 6164470Abstract: A hermetic seal for sealing a mouth of a wide-mouthed bottle having a body portion thinly formed by stretch blow molding, and a wide-mouthed bottle a mouth of which is sealed by the hermetic seal. A synthetic resin laminated sheet comprising an aluminum sheet or an aluminum foil as a base is punched into the same shape as a mouth of the wide-mouthed bottle to form the hermetic seal. The sheet is formed into a flat peripheral portion and a bellows inside the flat portion to have alternate multiple mountain and valley portions by press molding concurrently with the punching.Type: GrantFiled: May 11, 1999Date of Patent: December 26, 2000Assignee: A. K. Technical Laboratory, Inc.Inventor: Hiroshi Chino

Patent number: 6062407Abstract: A capping and sealing assembly for a sample-holding centrifuge container which features a self-sealing lid that forms a fluid-tight seal in an opening of the canister with a predetermined amount of force, with the force being dependent upon the centrifugal load to which the capping assembly is subjected. The lid includes a cover portion and a peripheral member surrounding the cover portion and extending transverse thereto. The lid is disposed within an open end of the container, with the peripheral member having a frusto-conical surface that faces the container's wall. A gasket is disposed about the frusto-conical surface, forming a fluid-tight and air-tight seal with the cylindrical wall of the canister. The gasket is received in a channel formed into the frusto-conical surface. A region of the channel includes a vent slot to facilitate removal of the container from the canister. A plurality of arcuate ribs extend across the cover portion, between opposed areas of the peripheral member.Type: GrantFiled: March 20, 1998Date of Patent: May 16, 2000Assignee: Beckman Coulter, Inc.Inventor: Patrick Q.
