Patent ID: 8413856

Claim:
A refillable system for dispensing a material by a constant-pressure gas, the system comprising: (a) a vessel for containing and dispensing the material, having a first vessel end, an opposing second vessel end, and a circumferential sidewall extending therebetween, the first end having a gas inlet and the second end having a material outlet manifold, the vessel further having a longitudinal axis and a transverse width; (b) a subsystem for generating and supplying constant-pressure gas through the gas inlet, the subsystem comprising: a container for containing a gas material in a liquid phase, a converter for converting the liquid-phased gas material into a gaseous-phased material, a pressure mechanism connected to the converter for dispensing the gaseous-phased material with constant-pressure of a user-determined value as the constant-pressure gas, and a pressure control operably connected to the pressure mechanism for actuation and de-actuation thereof and for changing the value of constant-pressure into a different one, wherein the apparatus is in gaseous communication with the vessel for transmitting the constant-pressure gas thereinto through the gas inlet; and (c) a force transfer device disposed within the vessel for transferring force from the constant-pressure gas to the material in the vessel for dispensation thereof, the force transfer device comprising: a crown, a tangential member attached to the crown and having a longitudinal axis substantially parallel to the longitudinal axis of the vessel, wherein the tangential member is configured with an outer area substantially parallel to the longitudinal axis, wherein the tangential member has a transverse width substantial less than the transverse width of the vessel, and a thruster attached to the tangential member and configured to penetrate the material in the vessel, wherein the crown is configured to be pressed by the constant-pressure gas so as to push the thruster into the material in the vessel toward the second vessel end and to be dispensed out of the material outlet manifold.
