  • Patent number: 7891522
    Abstract: An airless dispenser pump assembly includes a pump mechanism with an inlet valve that is configured to efficiently pump viscous fluids and that is able to be pre-primed when the pump mechanism is attached to a container. In one form, the inlet valve includes a seal member that seals an inlet port of the pump and an outer support member that secures the inlet valve to the rest of the pump mechanism. Two or more legs generally extend in a circumferential direction between the support member and the seal member in order to create a large flow opening for fluid flow through the inlet valve when opened and to rapidly close the inlet valve. The pump mechanism further includes an outlet valve that is configured to draw fluid back from a nozzle of the pump after dispensing in order to minimize build up around the nozzle.

  • Patent number: 7040509
    Abstract: A container for storage and dispensing of paint includes a unitary, molded plastic container body defining an interior volume and including an annular neck portion which is externally threaded and which defines the container opening through which the contents are dispensed. Included as part of the paint container is a dispensing spout which is positioned within the annular neck portion and includes a pouring lip, a wiping edge, and a paint brush receptacle with a plurality of drain-back apertures. The dispensing spout includes two threaded portions, one which engages the neck portion and the other which receives a removable closing cap. The cap is constructed and arranged to close the container opening. A transporting handle is provided and is attached directly to the dispensing spout such that the cap, spout, and handle can be provided as a subassembly for threaded engagement onto the container body.
