Publication number: 20130206868Abstract: A hose end dispenser for dispensing a carrier fluid and an aspiration fluid. The dispenser includes a body including a carrier fluid inlet and an aspiration fluid inlet. The dispenser includes a nozzle configured for dispensing the carrier fluid and the aspiration fluid. A valve includes a valve member and a valve housing. The valve member is rotatable in the valve housing about the axis of rotation for moving the valve member between an open position in which the valve member permits flow of carrier fluid through the valve member and a closed position in which the valve member blocks flow of carrier fluid through the valve member.Type: ApplicationFiled: August 6, 2012Publication date: August 15, 2013Inventor: Martin S.

Patent number: 7198180Abstract: A closure is removably attachable to a container and comprises a dispensing orifice and a tubular valve element that is biased closed blocking communication of the container with the orifice. By inverting the container so that a liquid contents of the container exerts pressure on the valve element, or by squeezing the container causing the liquid contents to exert pressure on the valve element, the valve element opens communication with the dispensing orifice allowing the liquid contents to be dispensed from the container. On removing the pressure from the valve element, the valve element resiliently closes the dispensing orifice.Type: GrantFiled: September 8, 2005Date of Patent: April 3, 2007Assignee: Continental AFA Dispensing CompanyInventors: Donald D. Foster, Martin S. Laffey

Patent number: 7036689Abstract: A child-resistant trigger sprayer includes a sprayer body having a barrel with an internal passage, and at least one first lug formed integrally with the barrel and extending radially outwardly from the barrel. A nozzle is rotatable on the barrel between at least one first position for dispensing liquid from the passage, and at least one second position for blocking dispensing of liquid from the passage. The nozzle has a flexible resilient skirt that is telescopically received over the barrel and the first lug on the barrel, and at least one pair of second lugs extending radially inwardly from the skirt for circumferential abutment on opposed sides of the first lug to block rotation of the nozzle in both directions from the second position toward the first position. The skirt is deflectable to distort the portion of the skirt carrying the second lugs radially outwardly so as to be rotatable past the first lug.Type: GrantFiled: April 22, 2002Date of Patent: May 2, 2006Assignee: Continental Afa Dispensing CompanyInventor: Martin S.

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: 6729560Abstract: The present invention pertains to a trigger sprayer which is connectable to two container volumes containing separate liquids. The sprayer has a trigger that is manipulated to draw the separate liquids into two separate pump chambers and then supply the two separate liquids from the pump chambers to a discharge passage of the sprayer. In the discharge passage the two separate liquids are mixed together prior to their being dispensed from the discharge passage as a spray.Type: GrantFiled: April 21, 2003Date of Patent: May 4, 2004Assignee: Continental Sprayers International, Inc.Inventors: Donald D. Foster, Martin S. Laffey, John A. Zurcher

Patent number: 6536686Abstract: The selector wheel is mounted to rotate about the axis of the nozzle cap, and a spray window and foaming sleeve are formed in the wheel offset from the axis. The window or sleeve is registrable with the offset spray orifice by rotating the wheel. Either window or sleeve can be brought into registry so that the discharge is spray or foam.Type: GrantFiled: March 18, 2002Date of Patent: March 25, 2003Assignee: Owens-Illinois Closure Inc.Inventors: Stephen A. Dukes, Martin S. Laffey

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. Laffey, Richard C. Sayers, Bradley J. Kimble, Gennaro R. Martire, Wing-Kwong Keung

Patent number: 5887761Abstract: A dual fluid dispenser comprising a dispenser body and a nozzle. The dispenser body has first and second pump chambers, a first intake port adapted for fluid communication with a first liquid source, a second intake port adapted for fluid communication with a second with a first liquid source, a second intake port adapted for fluid communication with a second liquid source, first and second intake liquid flow paths for passage of fluid from the intake ports to the pump chambers, and first and second discharge liquid passageways. A third discharge liquid passageway is defined at least in part by the dispenser body. The third discharge liquid passageway includes a mixing chamber and a spinner chamber downstream of the mixing chamber. The first and second discharge liquid passageways are configured for passage of liquid from the first and second pump chambers to the mixing chamber. The nozzle includes a nozzle orifice in fluid communication with the spinner chamber.Type: GrantFiled: January 22, 1997Date of Patent: March 30, 1999Assignee: Continental Sprayers International, Inc.Inventors: Donald D.

Patent number: 5704550Abstract: A liquid dispenser comprises a dispenser body and a flow restrictor. The dispenser body has a pump mechanism, an intake port adapted for fluid communication with a source of liquid, an intake liquid flow path providing fluid communication between the intake port and the pump mechanism, a discharge port, and a discharge liquid flow path providing fluid communication between the pump mechanism and discharge port. The flow restrictor is in the discharge liquid flow path and is moveable between first and second positions. The flow restrictor is configured for permitting fluid flow from the pump mechanism to the discharge port when the flow restrictor is in its first position, and is configured for at least partially impeding fluid flow from the pump mechanism to the discharge port when the flow restrictor is in its second position.Type: GrantFiled: December 8, 1995Date of Patent: January 6, 1998Assignee: Contico International, Inc.Inventors: Donald D.

Patent number: 5344053Abstract: A trigger sprayer apparatus is comprised of a sprayer housing and a vent housing that are formed independently of each other and are then assembled together. By providing a separate sprayer housing and vent housing, the sprayer apparatus may be produced in a manner that significantly reduces the occurrence of deformations or imperfections in the component parts of the apparatus. Molding the sprayer housing and vent housing separately enables the cylindrical interior surface of the pump chamber and the cylindrical interior surface of the vent chamber to be molded more accurately. Because the sprayer and vent housings are molded separately, a lesser amount of material is needed to mold each of these components and therefore shrinkage of the material as the components cool is significantly reduces. This eliminates the occurrence of deformations or sinks in critical areas of these component parts.Type: GrantFiled: March 9, 1992Date of Patent: September 6, 1994Assignee: Contico International, Inc.Inventors: Donald D. Foster, Martin S. Laffey
