Patent number: 5351863Abstract: A manually-operated dispensing pump for attachment to a container. The pump has a cylinder and a plunger with first and second skirts slidable in the cylinder. The plunger moves in one direction in an intake stroke and is manually-operated to move in the opposite direction in a pressurizing stroke. The plunger has a passage extending to a spray head on its end away from the cylinder for passing flowable product to the spray head. The pump has structure for connecting the interior of the container above the level of the product in it to the atmosphere during each pressurizing stroke of the plunger.Type: GrantFiled: March 8, 1993Date of Patent: October 4, 1994Assignee: Dupont Industries, Inc.Inventors: Howard E. Cecil, Thomas Dupont

Patent number: 5326237Abstract: A pump for moving a fluid includes an outer chamber having a first end wall portion containing a fluid entrance port and a second end wall portion containing a fluid exit port, a valve tube slidably contained within the chamber and having a first edge with a cut out section, adjacent the chamber first end wall portion, a first cup member within the valve tube having an outwardly flared side wall with a lip resiliently bearing against the valve tube adjacent the first edge and having a bottom wall smaller than the chamber first end wall portion, spacer connecting and spacing apart the first cup member bottom wall and the chamber first end wall portion, a plunger having a tubular stem portion containing a check valve plug and extending through the chamber exit port, and having a second cup member contained within the valve tube and also having a bottom wall with a hole opening into the stem portion and an outwardly flared side wall bearing against the valve tube and oriented to oppose the first cup member, suchType: GrantFiled: March 8, 1993Date of Patent: July 5, 1994Assignee: Dupont Industries, Inc.Inventors: Howard E. Cecil, Thomas Dupont

Patent number: 4272228Abstract: A high volume, low profile, quick acting, dispensing pump features valve members provided with flow restricting passages which accelerate the opening and closing action of the valve members and thus make it possible for the pump to handle large volume quickly. The low profile is achieved by wrapping the pressurized compartment around the intake of the pump.Type: GrantFiled: July 23, 1979Date of Patent: June 9, 1981Assignee: Security Plastics, Inc.Inventors: Louis F. Kutik, Howard E. Cecil

Patent number: 4271990Abstract: This pumping system provides a continuous discharge of flowable product withdrawn from a container into a pressurizing chamber and pumped by a pressurizing piston there into a storage chamber just ahead of a stationary discharge nozzle. A spring acts on an accumulator piston in the storage chamber to maintain a more uniform pressure on the product there at different times in each operating cycle so as to obtain a substantially non-pulsating discharge of the product. The accumulator piston tends to move in the same direction as the pressurizing piston due to a frictional coupling acting on the accumulator piston. Air is more easily purged from this pumping system.Type: GrantFiled: May 12, 1978Date of Patent: June 9, 1981Assignee: Security Plastics, Inc.Inventors: Louis F. Kutik, Howard E. Cecil

Patent number: 4231493Abstract: A pumping system is provided in which actuation of a piston and cylinder device is provided by a combination of a button and a lever. The lever magnifies the force applied to the button so that the pumping system operates at high pressure when pumping liquid product. On the other hand, when pumping air in priming the pump, the pumping system operates at very low pressure so that air can escape from the pump easily to aid in priming the pump.Type: GrantFiled: April 11, 1979Date of Patent: November 4, 1980Assignee: Security Plastics Inc.Inventors: Louis F. Kutik, Howard E. Cecil

Patent number: 4225060Abstract: A pumping system is disclosed in which a storage compartment formed by a spring loaded piston and cylinder assembly is provided with a spring which stays at a relatively constant length when pumping product to keep a relatively constant pressure on the product to maintain a steady stream or spray of product emerging from the pumping system. A vent structure is provided by a double seal arrangement which allows the mounting ring and a main cylinder of the pumping system to be made in one piece.Type: GrantFiled: December 29, 1978Date of Patent: September 30, 1980Assignee: Security Plastics, Inc.Inventors: Louis F. Kutik, Howard E. Cecil

Patent number: 4218198Abstract: A dispensing pump is provided with a non-throttling peripheral valve having a circular sealing edge with a diameter of greater than 3/4 inch and a thickness of less than 0.020 inch, and the valve is made of low density plastic material. The result is a pump which will operate at a very low, predetermined actuating pressure. A vent is included in the pump for venting a container to the atmosphere when air pressure in the container becomes reduced.Type: GrantFiled: November 2, 1978Date of Patent: August 19, 1980Assignee: Security Plastics, Inc.Inventors: Louis F. Kutik, Howard E. Cecil

Patent number: 4212332Abstract: The present pump has a manually operated actuator frictionally coupled to a floating valve to dispense liquid or other fluent product from a container. The floating valve coacts with the actuator and the pump housing to control:(1) the inlet flow of product from a dip tube in the container up into the pump;(2) the outlet flow of product from the pump to a discharge spout; and(3) the connection of an air vent opening to the inside of the container at the top at the proper time in each pumping cycle.The pump housing has a circular recess on the bottom for a snap fit on a complementary support bead, such as on the top lid of the container itself. A discharge selector valve on the discharge spout enables the selection of either a droplet spray discharge or a continuous flowing stream discharge from the pump. The pump actuator carries an end cap which may be removed for use as a scrub brush.Type: GrantFiled: February 21, 1978Date of Patent: July 15, 1980Assignee: Security Plastics, Inc.Inventors: Louis F. Kutik, Howard E. Cecil

Patent number: 4146155Abstract: A pumping system is disclosed in which a storage compartment formed by a spring-loaded piston and cylinder assembly cooperates with a trigger actuated, spring loaded piston and cylinder assembly to store some product during a pressure stroke and discharge that product on a subsequent intake stroke to maintain a stream or spray issuing from the system. In a preferred embodiment, the trigger is part of a lever so constructed as to apply to the trigger actuated piston and cylinder assembly a force which is greater than the force applied to the trigger by the finger of a person. The lever projects outwardly beyond the outlet orifice of the pumping system and forms a ramp and opening for returning drips from the outlet orifice to the trigger actuated piston and cylinder assembly and ultimately to the container. The storage compartment preferably includes a strainer which strains product flowing through the storage compartment in order to inhibit clogging of the outlet orifice of the pumping system.Type: GrantFiled: November 14, 1977Date of Patent: March 27, 1979Assignee: Security Plastics Inc.Inventors: Louis F. Kutik, Howard E. Cecil

Patent number: 4109832Abstract: A non-pulsating, non-throttling, vented pumping system with pressure release features is disclosed. This pumping system provides continuous dispensing of fluent product from a container in a relatively non-pulsating discharge which may be a stream or spray.Type: GrantFiled: May 9, 1977Date of Patent: August 29, 1978Assignee: Security Plastics, Inc.Inventors: Louis F. Kutik, Howard E. Cecil
