Patent number: 5884790Abstract: A self-braking closure cap for a container, such as a soft drink container, of the type that has a threaded finish portion with at least one raised thread defined thereon includes a top wall portion and a side wall portion having a substantially cylindrical inner surface. The inner surface has at least one raised helically oriented thread defined thereon that has a predetermined pitch. Advantageously, a restrictor is provided for frictionally resisting unscrewing of the closure cap from a container finish portion by bearing primarily against one side of one of the raised threads of the finish portion. Since the braking is achieved by frictional engagement having a significant axial force component, instead of a radial force component, braking can be achieved with a minimum of radial force being exerted on the closure. This preserves the stripping torque value of the closure at an acceptable level without the need to add additional material to reinforce the closure against deformation.Type: GrantFiled: October 30, 1997Date of Patent: March 23, 1999Assignee: Crown Cork & Seal Technologies CorporationInventor: Thomas M.

Patent number: 5845798Abstract: An anti-backoff closure assembly includes a container and a cap. The container has a neck portion forming an opening and having a protrusion and screw threads on an outer surface of the neck portion. The cap has on an inner surface a second protrusion, grooves, and a seal for releasably engaging the opening of the neck portion to form a leak free seal. The first and second protrusions engage to create an interference fit when the screw threads and the grooves are threadably engaged. Upon engagement, the second protrusion deforms the first protrusion sufficiently to form an indentation on the first protrusion that resists backoff as the pressure between the screw threads and the grooves is reduced as a result of plastic relaxation, thereby maintaining the leak free seal of the seal within the opening.Type: GrantFiled: March 15, 1997Date of Patent: December 8, 1998Assignee: The Procter & Gamble CompanyInventor: Frank Leslie Carrier

Patent number: RE38399Abstract: A child resistant cap including relatively thin threads which, when the cap is in a relaxed condition, are spaced from the bottle neck, said spacing permitting the cap to be squeezed inward at points on opposite sides of the cap so that the cap responds to the squeezing by expanding outward at points ninety degrees from the squeezing points so that stops on the cap at the cap expanding location will miss the stops normally engaged when in a relaxed condition, thereby permitting the cap to be removed from the bottle. The cap may also include a guide ring in the cap interior to guide the cap over the bottle neck to help ensure that the cap is centered on the bottle opening. The cap may include pressure pads on the cap skirt outside near the cap bottom showing the user where to press and stiffening the portion of the cap where pressure is to be applied. And, the cap may include a tamper indicating ring which will separate from the cap the first time the cap is removed from the bottle.Type: GrantFiled: July 15, 2002Date of Patent: January 27, 2004Assignee: Rexam Medical Packaging Inc.Inventor: Gary V.
