Abstract: A sealing assembly, for filling and sealing a reservoir of a gas lighter, comprising a cylindrical well (3), a plug (2) having a front section and a rear section, the front section comprising radial projections and at least one recess (4) to provide a fluid passage, the rear section having a circular bulge/bump portion (5), and a weld portion adapted to be melted by welding, wherein the plug is adapted to be moved from a first position (PI) in which a gas passage is, to a second position (P2), temporary seal position, in which a gastight contact is provided between the circular bulge portion of the plug and an inner wall of the well, and further from the second position to a third axial position (P3), definitive seal position, wherein the weld portion of the plug is definitely welded to the reservoir in a gastight manner.

Abstract: A gas lighter valve assembly that can be fitted easily and tightly into a gas lighter body or a well therein as a free-floating entity not fixed to the gas lighter body or well therein. The valve assemblies integration as a free floating entity within the lighter body or well therein avoids the necessity of interference fit. To avoid the necessity of interference fit, valve assembly positioning and stability is achieved by the use of an o-ring which is compressed by downward force exerted by a pressing cover upon a bushing or directly upon the o-ring. By eliminating the stress and friction typically caused by interference fit, the lighter body and reservoir can be made from a variety of materials including non-crystalline resins.

Abstract: Fuel supplies for fuel cells are disclosed. The fuel supplies can be a pressurized or non-pressurized cartridge that can be used with any fuel cells, including but not limited to, direct methanol fuel cell or reformer fuel cell. In one aspect, a fuel supply may contain a reaction chamber to convert fuel to hydrogen. The fuel supplies may also contain a pump. The fuel supply may have a valve connecting the fuel to the fuel cell, and a vent to vent gas from the fuel supply. Methods for forming various fuel supplies are also disclosed.
