Abstract: The present invention includes a composition having a co-continuous interconnecting channel morphology. These co-continuous interconnecting channels are predominately occupied with a polymer and particles that control the surface properties of the composition. The polymer composition may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.

Abstract: An injection molding press apparatus for use with a variety of different interchangeable molding tools that allows the simultaneous molding of different parts. The interchangeable molding tools are custom designed to form a desired part. Each interchangeable molding tool allows for the easy replacement of different types of molding tools for the molding of different parts without the need of an entire mold replacement. A preferred embodiment of the invention comprises a baffle sorting system for injection molding machines thereby increasing the allowing the simultaneously molded different parts to be ejected from the machine without the need of separating the different parts. This increases the speed of each production run.

Abstract: An injection molding apparatus having an A side and a B side for use with interchangeable molding tools that allow the center gating of a part. Center gating directly into a molding tool provides a uniformly stress resistant cylindrical part. The use of interchangeable molding tools provides easy replacement of tools that are designed to produce a variety of different parts. Each interchangeable molding tool provides a runner tool distribution system to allow injected material to enter directly into the center of a part to be molded. Once the part is molded, the runner that is formed in the runner tool distribution system is separated from the molded part. The molded parts are then simultaneously released from the mold assembly.

Abstract: A water jacket assembly for use in injection mold systems, and particularly with heterocavity injection mold systems. The water jacket assembly comprises a sleeve construction of material with high heat-transfer properties. A conduit is beveled into the outside perimeter of the sleeve forming a circulation channel. The inside perimeter of the sleeve is fashioned to receive an individual injection mold. A mold base slideably received the water jacket and cooling fluid is circulated from the mold base through circulation channel in the water jacket, and then back to the mold base. A fluid input plug and fluid output plug extend from the mold base and are received by the apertures in the individual mold for additional cooling.

Abstract: A baffle sorting system for use with injection mold machines that produce different mold products from a plurality of mold cavities during the same production run whereby at least one baffle extends perpendicular to one plate in a mold between two mold cavities, and corresponding slot on the second plate of a mold receives the baffle when both plates are coupled. When the product is ready to be ejected from the machine, both plates separate, but the baffle prevents the products of one mold from intermingling with the products of a second mold. The products drop down into a collection device for further processing or packaging. Alternatively, the baffles are positioned between the A plate and the B plate during the ejection phase of the molding cycle, then retracted from the mold machine during the injection phase.

Abstract: An assembly for the receiving of a plurality of plastic parts initially interconnected to one another by runner structures in an array and formed from a multi-cavity plastic mold such that the subject assembly separates the plastic parts from the runner structure, ejects and delivers the runner structure into a recycling assembly and concurrently but independently delivers each of the plastic parts into separate containers through the provision of a delivery structure associated with the subject assembly.

Abstract: A pumping assembly for dispensing product from a container is provided with a lever having a catch which locks with a lip on a closure to hold the lever in a depressed position.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
