Abstract
A dispenser for a dispensable fluid, such as, for example, a hydrocarbon fuel, is of the type comprising an outer canister containing a pressurized propellant, an inner bag containing the dispensable fluid, and a normally closed valve. The inner bag has a flexible wall with an orifice having a margin. Two clamping members, which may be snap-fitted to each other, clamp the valve to the inner bag at the margin of the orifice. A resilient washer is disposed outside the inner bag, in intimate contact between one of the clamping members and the margin of the orifice, so as to form a fluid-tight seal around the orifice.
