Publication number: 20070138213Abstract: An assembly including a pump attachment particularly adapted to form an nonaerosol pump sprayer, and a method of using the same. The apparatus desirably includes an attachment having a pump sprayer which is pressurized on the upstroke enabling the sprayer to be shipped and stored in a relaxed position. The attachment includes a body, a coupling, a shaft, a piston, an inlet valve and a biasing member. The body defines an elongate chamber having the first end, second end, and an interior wall extending between the first end and second end. The coupler is sized and shaped to secure the body to the neck of a container. The shaft extends through the opening in the first end of the chamber and defines an internal flow channel. The piston is reciprocally mounted within the chamber and includes an inner annular surface surrounding the shaft and an outer annular surface sized and shaped to form a sealing engagement with the interior wall of the body.Type: ApplicationFiled: February 28, 2007Publication date: June 21, 2007Applicant: HAYES PRODUCTS, LLCInventors: Donald Shanklin, Ronald Englhard

Publication number: 20060261187Abstract: A sprayer head assembly comprises a chemical passage, a carrier fluid passage, and a housing that has an outer surface and an inner surface, which defines a valve chamber configured to be in communication with the chemical and carrier fluid passages. A valve is moveably positioned within the valve chamber between at least a first position, a second position and a third position. The valve defines a first passage, a second passage and a chemical inlet passage that is in communication with the second passage. The valve is configured such that, in the first position, the valve blocks the chemical and carrier fluid passages, in the second position, the first passage is configured to be in communication with the carrier fluid passage while the valve blocks the chemical fluid passage, and in the third position, the second passage is configured to be in communication with the carrier fluid passage and the chemical inlet passage is configured to be in communication with the chemical passage.Type: ApplicationFiled: May 3, 2006Publication date: November 23, 2006Inventors: Ronald Englhard, Donald Shanklin

Publication number: 20060060613Abstract: A noncontainer pressurizing pump sprayer includes a body, which defines a chamber. A piston is positioned within the container and is coupled to a shaft. The piston divides the chamber into an upper section and a lower section. An inlet valve is positioned on the body and permits flow of fluid into the lower section but restricts flow out of the lower section. The shaft of the piston is coupled to a handle. A spray nozzle includes an actuator that is coupled to a control valve and a discharge outlet that is in fluid communication with the lower section of the chamber. In one embodiment, a tube extends continuously from a point upstream of the control valve to a point downstream of the control valve. In another embodiment, a tube is coupled to the piston and extends through the handle. In another embodiment, the tube extends continuously from the spray nozzle and is coupled to the piston.Type: ApplicationFiled: September 12, 2005Publication date: March 23, 2006Inventors: Ronald Englhard, Donald Shanklin

Publication number: 20060032943Abstract: The present invention relates to a chemical sprayer that includes a sprayer head assembly and a container. The container defines a cavity for storing a chemical to be sprayed. The sprayer head assembly includes a chemical passage, a carrier fluid passage, a vent passage, a valve chamber and a valve. The chemical passage is communication with the cavity. The carrier fluid passage is in communication with a carrier fluid source. Both the carrier fluid and chemical passages are in communication with the valve chamber. The valve is moveably positioned within the valve chamber and defines at least partially a first passage and a second passage. The first passage is configured so as tube in communication with the chemical passage when the valve is in an open position. The second passage is configured so as to be in communication with the carrier fluid passage when the valve is in the open position.Type: ApplicationFiled: October 17, 2005Publication date: February 16, 2006Inventors: Donald Shanklin, Ronald Englhard

Publication number: 20050199751Abstract: Disclosed are embodiments related to a chemical sprayer that comprises a sprayer head assembly and a container. The container defines a cavity for storing a chemical to be sprayed. A valve may be longitudinally moveable from an open position to a closed position. In the closed position, the valve may block a chemical passage, a vent passage, and a carrier fluid passage. In an open position, these passages are opened.Type: ApplicationFiled: February 14, 2005Publication date: September 15, 2005Inventors: Donald Shanklin, Ronald Englhard

Publication number: 20050189436Abstract: A sprayer head assembly comprises a sprayer head and a valve for controlling the flow of fluid through the assembly. The sprayer head comprises a chemical passage, a carrier fluid passage and a vent passage. A generally cylindrical bore is in communication with the chemical, vent carrier fluid passages. The valve is moveably positioned within the bore. The valve is moveable between a first position and a second position. The valve comprises a first passage and a chemical inlet passage that is in communication with the first passage. In the first position, the valve blocks the vent, chemical and carrier fluid passages. In the second position, the first passage is configured to be in communication with the carrier fluid passage while the chemical fluid passage is in communication with the chemical inlet passage. The valve defines a suction generating recess positioned within the first passage.Type: ApplicationFiled: February 28, 2005Publication date: September 1, 2005Inventors: Donald Shanklin, Ronald Englhard
