Additionally, the passage's rear portion may be configured so as to allow this member to fit on that portion of the spray head which is configured to receive a spray nozzle.Type: GrantFiled: September 26, 2005Date of Patent: April 8, 2008Assignee: Bowles Fluidics CorporationInventors: Russell D. Hester, Rosa Korobkov, Alan Santamarina, Steve Crockett, Shridhar Gopalan

Publication number: 20080078846Abstract: A liquid condiment dispenser includes a container with a separation board to define an upper space and a lower space. An outlet is defined through a hollow body defining the lower space. A rod cooperated with a button extends through the separation board and has a first seal ring to removably seal the hole of the separation board. A second seal ring is securely engaged with an inner periphery of the second space so that when the rod is pushed, the first seal ring allows the liquid condiment in the upper space to flow to the lower space and liquid condiment is pushed from the outlet in the distal end of the hollow body. The rod is pushed upward by a spring to seal the hole again when releasing the button.Type: ApplicationFiled: September 14, 2006Publication date: April 3, 2008Inventor: Jui-Cheng Tsai

Patent number: 7311227Abstract: A venting system of a manually operated trigger sprayer vents the interior of a liquid container connected to the trigger sprayer. The trigger sprayer is provided with a vent chamber that surrounds the pump chamber, and a vent piston that surrounds the pump piston. The vent piston is received in the vent chamber for reciprocating movements between a vent closed and vent opened position in the vent chamber, and the vent chamber having two different interior diameter sections with a larger interior diameter section reducing drag on the vent piston when the vent piston is moved to the vent opened position.Type: GrantFiled: July 7, 2005Date of Patent: December 25, 2007Assignee: Continental AFA Dispensing CompanyInventor: Donald D. Foster

Patent number: 7306122Abstract: A venting system of a manually operated trigger sprayer vents the interior of a liquid container connected to the trigger sprayer. The trigger sprayer is provided with a vent chamber that surrounds the pump chamber, and a vent piston that surrounds the pump piston. The vent piston is received in the vent chamber for reciprocating movements with the pump piston in the pump chamber. The reciprocating movement of the vent piston alternatively opens the vent chamber to the exterior environment of the trigger sprayer and thereby vents the interior of the liquid container connected to the trigger sprayer, and closes the vent chamber thereby sealing the interior of the liquid container from the exterior environment.Type: GrantFiled: October 8, 2004Date of Patent: December 11, 2007Assignee: Continental AFA Dispensing CompanyInventors: Jeffrey P. Stark, Walter J. Clynes

Patent number: 7303150Abstract: A nozzle has a front, a back, and at least one flat surface extending therebetween. A door is coupled to the intersection of the front and flat surface by a live hinge. Optionally, the door has a portal within which a screen is mounted. The exterior surface of the door is provided with one or more curved hooks and the flat surface is provided with corresponding number of mating slots with which the hook(s) engage(s). Preferably, the interior of the door is provided with one or more curved hooks and a corresponding number of mating slots are provided on the front of the nozzle on an edge opposite the live hinge. Preferably, the door is provided with a tab which extends outward beyond the periphery of the nozzle on the edge of the door opposite the live hinge.Type: GrantFiled: November 22, 2005Date of Patent: December 4, 2007Assignee: MeadWestvaco CorporationInventor: George R. Hildebrand

Patent number: 7300001Abstract: A pump-dispensing atomizer includes a dispensing pump with a closure to engage with a container. The dispensing pump includes a pressing button with a booster chamber formed inside, a nozzle with one end extending from the pressing button and a probe formed with at least one section. An interior of the nozzle is formed with a guide chamber, and one end of the guide chamber is connected to the booster chamber. The guide chamber has at least one expanding sub-chamber. After the probe is disposed in the guide chamber, a boosting channel is formed between the expanding sub-chamber and the stepped section. Moreover, the pressure accumulator is mounted on the other end of the nozzle, which is formed with a spraying opening communicated to outer environment. As such, the pressure of liquid flowing in the nozzle will be increased effectively so that liquid is sprayed out with a higher pressure to increase the spraying speed of the liquid.Type: GrantFiled: September 2, 2005Date of Patent: November 27, 2007Inventor: Roy Kuo
