Abstract
Embodiments of the present invention are designed to interface between a package, either rigid or flexible and an apparatus to push a seal valve from the housing. Once the container is inserted into the “nest” with valve, opened fluid flow is achieved. Once the container with the valve is removed from the “nest” the valve will self close, with no operator interaction to stop flow of the product.
Claims20
A fluid dispensing valve having an open configuration wherein fluid is permitted to flow and a closed configuration wherein fluid is prevented from flowing, the fluid dispensing valve comprising:
- a housing;
- and
- a seal disposed within the housing;
- the seal comprising a resilient member, the resilient member comprising a base and a stem, the base comprising a dome, the stem extending from the dome and terminating at a closed distal end;
- wherein at least a portion of the stem sealingly engages the housing when the fluid dispensing valve is in the closed configuration.
A fluid dispensing valve comprising:
- a housing defining an interface cavity and a seal cavity;
- and
- a seal, the seal comprising a base, a stem extending therefrom, and a gasket attached to the base;
- the stem disposed within the seal cavity and the gasket disposed within the interface cavity, wherein the stem is moveable within the seal cavity from an extended position to a compressed position;
- in the extended position, the base being dome-shaped and, in the compressed position, the base being elastically deformed to define an annular crease.
A fluid dispensing assembly:
- a container, the container having an outlet hub;
- and
- a fluid dispensing valve, the fluid dispensing valve comprising a housing and a seal, the housing defining an interface cavity and a seal cavity, the housing having a mating surface, the seal disposed within the seal cavity, and the interface cavity defining threads, the threads being threadingly engaged to the outlet hub;
- the seal comprising a base and a stem, the base comprising a dome, the stem extending from the dome and terminating at a closed distal end, wherein the stem comprises a beveled surface, the beveled surface of the stem sealingly engaging the mating surface of the seal cavity.
