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 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: An improved valve member, aerosol dispenser valve containing the valve member, aerosol container for dispensing moisture curable foams, and moisture curable foam and dispenser, in which the valve member is made of a glass filled polyolefin. The polyolefin is preferably a polyethylene. The glass content is between about 2% and about 40%, more preferably between about 10% and about 30%; and most preferably between about 15% and about 25%.

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.
