Patent number: 5860545Abstract: A closure tear handle which prevents damage to the closure tear skirt under large application forces when the closure is applied to the bottle; this invention also provides a tear skirt which is easier for consumers to remove. A weak region is placed at the base of the intersection of the tear handle and the wall of the tear skirt. This weak region of the closure is designed such that upon contact with the neck finish of a bottle, which puts the tear skirt into tension, it attracts the tensile forces and relieves stress from the adjacent weak point of the closure tear skirt to prevent damage to this area that would be offensive to consumers and result in wasted product.Type: GrantFiled: April 17, 1997Date of Patent: January 19, 1999Assignee: The Procter & Gamble CompanyInventor: Eric R. Bartsch

Patent number: 5857580Abstract: A closure for a beverage bottle includes a plug element having a disk shaped head portion and a hollow cylindrical portion which seals with the inner surface of the opening of the bottle. An annular projection is formed around the circumference of the bottle 12 near its mouth. The closure further includes a cap element which fits over the plug element and which includes with a skirt having an annular recess which locks onto the annular projection of the bottle. A first precut line is provided in the cap, extending around its circumference and a second precut line portion extends from the distal edge of the skirt to the first precut line across the annular recess.

Patent number: 5829613Abstract: A container closure system comprising a threaded cap and a threaded neck wherein the cap is affixed to the neck by direct axial application so that the mating threads slip past one another and into engagement. The cap further includes sealing means to capture and constrict the outer diameter of the neck, and valve means to plug the container opening in the neck and expand the outer diameter of the neck, so that the sealing means and valve means cooperate to improve sealing of the cap and neck. The cap and neck further include tamper-indication means to prevent removal of the cap without activation thereof.Type: GrantFiled: October 20, 1995Date of Patent: November 3, 1998Assignee: Superseal CorporationInventors: Emanuel Erick Wohlgemuth, Charles Hogan

Patent number: 5829611Abstract: A tamper-evident cap and overcap including a cap with an upstanding cap portion and a lower base, the base defining a circumferential channel. An overcap is positioned to enclose the upstanding cap portion, with the overcap carrying a circumferential projection or skirt permanently retained in the circumferential channel, typically by force-fit. A frangible line of weakness permits separation of the overcap and the circumferential projection. At least the circumferential projection, and typically also the overcap, are of a color that contrasts with the color of the cap, so that, upon removal of the cap, the remaining edge of the circumferential projection gives an indication that the overcap has been removed.Type: GrantFiled: October 7, 1996Date of Patent: November 3, 1998Assignee: Creative Packaging Corp.Inventor: James M. Beck

Patent number: 5823377Abstract: A plastic screw cap for the closure of a plastic container is provided for the closure of a container made of plastics. The screw cap has a simple configuration similar to corresponding closures for metal containers, but nevertheless ensures stable and sealed seating of the closure on the container opening. The screw cap is provided with an extension, extending radially over the side of the screw cap, which is made from a material which can be welded to the material from which the container lid is made.Type: GrantFiled: March 24, 1995Date of Patent: October 20, 1998Assignee: Jacob Berg GmbH & Co. KGInventor: Gunter Jakob Krautkramer

Patent number: 5775528Abstract: A container closure system comprising a threaded cap and a threaded neck wherein the cap is affixed to the neck by direct axial application so that the mating threads slip past one another and into engagement. The cap further includes sealing means to capture and constrict the outer diameter of the neck, and valve means to plug the container opening in the neck and expand the outer diameter of the neck, so that the sealing means and valve means cooperate to improve sealing of the cap and neck. The cap and neck further include tamper-indication means to prevent removal of the cap without activation thereof. The tamper-indication means includes a novel skirt, pull tab and membrane configuration. The container neck may include interrupted threads which do not traverse the parting line and an additional annular seal below the threads on the container neck.Type: GrantFiled: November 19, 1996Date of Patent: July 7, 1998Assignee: Superseal CorporationInventors: Emanuel E. Wohlgemuth, Charles Hogan

Patent number: 5769252Abstract: A container closure which can be converted from a child resistant configuration to a non-child resistant configuration. The container closure includes an external cap, an internal cap and a locking element. The locking element is inserted between the external cap and internal cap to form the non-child resistant configuration.Type: GrantFiled: December 5, 1996Date of Patent: June 23, 1998Assignee: Volpe and Koenig, P.C.Inventor: Anthony S. Volpe

Patent number: 5770290Abstract: An easy open end for food and beverage cans having reduced aluminum content is provided in an end having a metal polymer metal laminate construction. An opening panel as defined in the end body by a pair of first and second spaced apart score lines disposed in the first and second major surfaces, respectively. Each of the first and second score lines define an area of reduced thickness for both the metal layer and the adjacent polymer layer. The opening panel can be displaced from the remainder of the end body to provide an easy opening can by perforating the end body at a point along the first and second score lines.Type: GrantFiled: September 3, 1996Date of Patent: June 23, 1998Inventors: Robert J. McHenry, Dominique Petit

Patent number: 5740933Abstract: A tamper indicating, child proof, container cap designed for easy manipulation by arthritic fingers of a user includes an annular tear strip and a rotatably indexing latch finger on the cap which engages a raised annular retainer ridge with bypass opening on the neck of the container. A tactile indicator of the rotational location of the bypass opening is under the tear strip for sensing by the user's finger that is in simultaneous contact with the cap when the tear strip is removed. A lower ridge includes an index key for orienting the latch finger away from the bypass opening during assembly of the system. The top of the cap includes an extended axial length portion that is shaped for easy grip by arthritic fingers.Type: GrantFiled: August 15, 1994Date of Patent: April 21, 1998Assignee: American Safety Closure Corp.Inventors: Vincent N.

Patent number: RE37243Abstract: A blow molded container has a cylindrical neck portion with novel seven circumferentially spaced continuous spiral thread configurations on its exterior to immediately receive and engage an improved tamper indicating flexible cap comprising a top with an annular depending wall on its peripheral edge and seven circumferentially spaced continuous spiral thread configurations on the inner surface of the annular depending wall. The novel constructions enable the tamper indicating flexible cap to immediately engage the lead-in ends of the seven circumferentially spaced thread patterns on the exterior of the neck of the container without the heretofore necessary rotation of the prior art caps in order to engage the single spiral thread configuration on the neck of the container.Type: GrantFiled: March 22, 1996Date of Patent: June 26, 2001Assignee: Portola Packaging, Inc.Inventors: Luca Molinaro, Robert E.

Patent number: RE36729Abstract: A thin-walled, wide mouth molded plastic container is provided with a tamper evident band initially molded as a straight-walled cylinder spaced outwardly of the lip of the container and connected thereto by a frangible horizontal bridge. The upper edge of the cylindrical band extends above the level of the container lip. Subsequent to molding and preferably before capping, the band is curled inward by application of a curling tool. The container lid is axially applied, the outer edge of the lid displacing the curled band outward. The resilience of the band and bridge permits outward deflection and immediate restoration of the curl to its initial position. The curl prevents removal of the lid without fracture of the bridge and removal of the tamper-evident band.Type: GrantFiled: September 17, 1996Date of Patent: June 13, 2000Assignee: Portola Packaging, Inc.Inventors: Daniel Luch, Rawson Chenault
