Patent number: 8506560Abstract: A container for a cryosurgery device which includes a cryogen bottle. The container includes a container body including an internal space sufficiently large to hold the cryogen bottle; a valve actuation assembly mechanically coupled to the container body, the valve actuation assembly configured to actuate a valve on the cryogen bottle; and a reservoir positioned relative to the valve actuation assembly so that the reservoir receives cryogen from the cryogen bottle when the valve on the cryogen bottle is actuated using the valve actuation assembly.Type: GrantFiled: December 11, 2008Date of Patent: August 13, 2013Assignee: MSD Consumer Care, Inc.Inventors: Robert T. McBride, Jr., Sergio Gedanke, Wing-Kwong Keung, Leonora M. Brozell

Patent number: 8308004Abstract: A dispensing package includes a container having a neck finish with an axis, a non-circular cross section in a plane perpendicular to the axis, and at least one circumferentially extending external engagement element on the neck finish. A closure has a wall received over the container neck finish. The wall has a non-circular cross section corresponding to the non-circular cross section of the neck finish and at least one internal circumferentially extending engagement element in engagement with the external engagement element on the neck finish. The internal and/or external circumferentially extending engagement element has a shallow lead-in angle to enable press-fit of the closure onto the container neck finish and a steep back angle to retard removal of the closure from the neck finish. Rotation of the closure on the neck finish is prevented by the non-circular cross sections of the neck finish and the closure wall.Type: GrantFiled: November 22, 2005Date of Patent: November 13, 2012Assignee: Rexam Healthcare Packaging Inc.Inventor: Wing-Kwong Keung

Patent number: 7721907Abstract: A child-resistant closure includes a base, and a lid integrally molded and coupled to the base by a hinge. The lid has a latch arm resiliently extending from a periphery opposite the hinge and having oppositely extending tabs adjacent to a free end of the latch arm. The base has an external recess for receiving the latch arm and spaced ledges in the recess for engagement by the tabs to lock the lid in a closed position. The latch arm is engageable by a user to pivot the latch arm radially inwardly within the passage and release the tabs from the ledges so the lid can be pivoted toward an open position. The tabs and the ledges are recessed radially inwardly from the outer surface of the latch arm in the closed position of the lid with the tabs engaged beneath the ledges.Type: GrantFiled: November 22, 2005Date of Patent: May 25, 2010Assignee: Rexam Closure Systems Inc.Inventor: Wing-Kwong Keung

Patent number: 7404495Abstract: A child-resistant dispensing closure includes a base having a deck with a dispensing opening and a peripheral skirt. A lid is integrally molded with the base and coupled by a hinge to a periphery of the base so as to be pivotable between closed and open positions. One of the base and the lid has a latch arm resiliently extending from its periphery diametrically opposite the hinge. The latch arm has a pair of oppositely extending tabs adjacent to a free end of the arm. The other of the base and the lid has an axial passage for receiving the latch arm, and a pair of laterally spaced ledges in the passage for engagement by the tabs to lock the lid in the closed position. The latch arm is directly manually engageable by a user from a radial direction external to the closure to pivot the latch arm radially inwardly within the passage and release the tabs from the ledges so that the lid can be pivoted to the open position.Type: GrantFiled: July 28, 2003Date of Patent: July 29, 2008Assignee: Rexam Closure Systems Inc.Inventor: Wing-Kwong Keung

Patent number: 6997397Abstract: A trigger sprayer includes a sprayer body having a barrel with an internal passage, and a nozzle mounted over an open end of the barrel for rotation between dispensing and non-dispensing positions. The nozzle has a plug that is received in the open end of the barrel passage. The plug has laterally opening windows positioned for selective registry with an internal axial slot in the wall of the barrel passage adjacent to the open end of the barrel. The windows in the plug connect with fluid outlets in the nozzle. The nozzle is rotatable around the end of the barrel selectively for bringing the windows into registry with the slot in the barrel to dispense fluid from the end of the nozzle.Type: GrantFiled: April 8, 2003Date of Patent: February 14, 2006Assignee: Continental AFA Dispensing CompanyInventors: Wing-Kwong Keung, Martin S.

Patent number: 6446882Abstract: The invention is a trigger sprayer comprising a tubular nozzle bushing and a nozzle cap rotatable on the bushing. The nozzle cap has an end wall with a first swirl chamber formed on the rear face thereof offset from the axis. Passages to a second chamber are diametrically opposite the first chamber. Both chambers have orifices directed out the front of the cap. The first orifices is surrounded by a foaming sleeve. The second orifice is positioned forward of the first orifice so that the spray cone emanating from the second orifice does not hit the foaming sleeve. The cap can be rotated to connect liquid from the delivery tube to the swirl chamber for one or the other orifices.Type: GrantFiled: February 2, 2001Date of Patent: September 10, 2002Assignee: Owens-Illinois Closure Inc.Inventors: Stephen A.

Patent number: 6364173Abstract: This pump dispenser has a downward tubular support providing a lead-in for a resilient closure. The closure is formed with an upwardly facing inward lead-in chamfer and spaced deep arcuate recesses in the top surface so that the wall between the recesses and the inner diameter is outwardly resilient to permit an attachment flange to stretch the wall outward and permit snap passage of the attachment flange. In this manner the closure is permanently attached to the pump body without the need for welding or separate attaching parts.Type: GrantFiled: February 21, 2001Date of Patent: April 2, 2002Assignee: Owens-Illinois Closure Inc.Inventors: Martin S.
