Abstract
A rechargeable dispensing apparatus, particularly suitable for use as a fire extinguisher, includes a generally spherical, enclosed dispensing container adapted to receive a liquid extinguishant therein, and has a flexible pickup tube shiftably confined therewithin which is provided with a weighted orifice for maintaining the latter at the bottom of the container below the level of remaining liquid within the container, whereby to allow continuous dispensing of the extinguishant in spite of tilting or turning of the apparatus by the user during the dispensing operation. A single, ordinary faucet-type valve, adapted to interchangeably couple with a filler pipe and a dispensing hose, provides the two-fold function of permitting introduction of liquid under pressure into the container and maintaining the same in a pressurized storage state, while also allowing the user to selectively release the liquid from the container through the dispensing hose, without the need for multiple, specially configured valve mechanisms.
