Abstract
Systems and apparatuses for fluid delivery. A system may include a container for containing fluid and a pump for pumping fluid from the container. There may be a dispensing outlet valve for mediating fluid flow through a dispensing outlet of the container, wherein the dispensing outlet valve is configured to permit flow from the container out the dispensing outlet when the pump is being pumped, and to automatically inhibit fluid flow from the container through the dispensing outlet when the pump is not being pumped.
Claims21
-101. (canceled)
A portable dispensing container comprising:
- a container for containing liquid, the container including at least one opening;
- a device in fluid communication with the at least one opening for controlling the flow of liquid through the at least one opening, the device comprising:
- a body with at least one through passage including an upstream portion for receiving liquid and a downstream portion for delivering liquid;
- a plug biased against a seat in the body, the plug precluding the flow of liquid from the upstream portion to the downstream portion when the plug is seated against the seat, the plug including a first frontal area and a second frontal area, the first frontal area being smaller than the second frontal area;
- wherein, when the plug is seated against the seat, force caused by pressure in the body acts on the first frontal area;
- wherein, when the plug is unseated from the seat, forces caused by pressures in the body act on the second frontal area;
- and
- wherein a first pressure applied to the first frontal area sufficient to unseat the plug from the seat is greater than a second pressure applied to the second frontal area sufficient to maintain the plug unseated from the seat.

A portable dispensing container comprising:
- a container for containing liquid, the container including at least one opening;
- a liquid delivery hose in fluid communication with the container for conveying liquid from the container;
- a fluid recovery hose in fluid communication with the container for conveying recovered fluid to the container;
- and
- at least one device in fluid communication with at least one of the liquid delivery hose and the fluid recovery hose, the device comprising a plurality of fluid channels wherein each fluid channel is sized to inhibit propagation of a flame through the fluid channel.
