Abstract: A lever of an aerosol valve having a valve stem includes a lever member having first and second end portions, a first aperture disposed in the first end portion, and a second aperture disposed between the first and second end portions. The first aperture is configured to permit the lever member to be releasably received over a valve stem of an aerosol valve in a dispensing position, in which the second end portion extends outwardly from the valve stem to provide for pivotally displacing the valve stem to dispense product therethrough. The second aperture is configured so that the lever member fits in a stored position with the second aperture around a portion of the valve stem, and the first and second end portions extending alongside the valve stem, such that the lever member may be stored under a cover.

Abstract: A system for dispensing polyurethane foam from DOT-39 compliant tank, includes a compressor having an outlet through which air is supplied, and a booster coupled to the outlet of the compressor. The booster provides a supply of compressed air at a pressure of between about 160 and about 200 pounds per square inch. At least two bladderless tanks having an internal volume sized less than 1,526 cubic inches to comply with DOT-39 specifications each contain a quantity of a polyurethane foam component that is sufficient to fill at least 70 percent of the internal volume of the bladderless tanks. A first valve on the bladderless tanks connects to the high pressure outlet of the booster. A second valve is adjacent the bottom of each bladderless tank. A dispenser for dispensing the polyurethane foam component is connected to the second valve on each of the bladderless tanks.

Abstract: A cover and trigger assembly is provided that includes having a valve that can be actuated for dispensing the contents of the can through an outlet of the valve. The assembly includes an annular component having a helical surface is secured to the can, and a cover coupled to the annular component. The cover has an opening through which a trigger extends, and the cover is rotatable relative to the helical surface on the annular component for rotatably raising or lowering the cover relative to the annular component. The raising or lowering of the cover respectively prohibits or permits movement of the trigger member to actuate the valve, thereby controlling dispensing operation of the valve.

Abstract: A dispensing applicator for reactive components is provided that comprises a valve assembly having at least two flow paths being separate from each other such that at least a first component in a first flow path and at least a second component in a second flow path may not mix in the valve assembly, where there is a passage in each of the at least two flow paths that have one or more exit openings in a peripheral wall of each passage. The dispensing applicator further comprises a resilient flow control band surrounding the periphery of each passage and the one or more exit openings in the peripheral wall of the each passage to prevent cross-over flow of one component into the flow path of the other component. The resilient flow control bands may be positioned anywhere along the flow path leading to a mixing chamber for the reactive components.

Abstract: A method of dispensing polyurethane foam from DOT-39 compliant tank, the method includes providing DOT-39 compliant tanks of each of the components of the polyurethane foam, each tank having at least two valves. At least one valve of each of the DOT-39 compliant tanks is connected to a source of pressure. At least one valve of each of the DOT-39 compliant tanks is connected to a dispenser to mix the components and dispense the foam under pressure.

Abstract: A cover comprising a first cap section for covering the dispenser valve and a second annular section having at least two mounting members configured to engage a circular lip on the aerosol can and firmly attach the second section to the aerosol can. The second annular section further comprises a removable portion that is less than the entire thickness of the second section and includes at least one of the mounting members, such that removal of the removable portion permits the cover to be detached from the can. The cover further includes a tamper evident portion between the first and second sections. An opening force exerted on the first cap section prior to removing the removable portion causes either the tamper evident portion or the removable portion to at least partially separate from the second section.

Abstract: A rectangular prismatic carton and method for bulk packing pistons or other similar products are provided, which improve the fill efficiency of the product without increasing the risk of damaging a percentage of the packaged product. The carton comprises a carton having length l, width w, and height h, such that h is greater than l and w, the top and a bottom being formed by overlapping flaps. The carton has a ratio of the opening perimeter of the carton to the height of the carton is less than about 2. The carton provides a reduced opening cross-section that allows for improved fill efficiency when filling the carton with pistons or other product and leaving a volume of unfilled space remaining within the carton.

Abstract: A valve assembly for an aerosol can comprises a valve conduit having an inlet, an outlet, a valve seat in the flow path between the inlet and the outlet, and a resilient mounting of a valve member that permits relative movement of the valve member relative to the valve conduit. The valve member further comprises a valve element that is movable to sealingly engaging the valve seat, and a stem projecting from the valve member through the outlet of the valve conduit. During the movement of the valve member relative to the valve conduit, the movable tapered sealing surface associated with the valve member is configured to engage and concentrically align with a tapered valve seat on the valve conduit to establish an effective seal against the valve seat.

Abstract: The inventive dispenser comprises a cap and dispenser tube assembly for delivering a foamed product below the surface of a liquid through the dispenser tube. The dispenser tube pivots between a dispensing position and a non-dispensing stowed position, which allows for convenient cleaning of the dispensing tube. The cap further comprises a removable portion between a first and second section of the cap that restricts movement to prevent operation of the dispensing valve until the removable portion is detached by the consumer. The cap also includes a tamper resistant removable pull tab for securing the dispenser tube in the stowed position until the pull tab is detached by the consumer.

Abstract: In a gun for dispensing a fluid component, a valve assembly controls the dispensing of the fluid component. The valve assembly includes a needle or valve member and a cup assembly having a passage for receiving the needle assembly. A channel system allows flow of the component through the passage past a seal. An actuator assembly may be provided for providing relative movement between the cup assembly and the needle assembly from a valve-closed position to a valve-open position in which the seal is located upstream from a downstream end of the channel system to permit flow of the component through the passage.
