Abstract
Abstract A unit having a reservoir for containing a supply of fuel, a valve assembly associated with the reservoir to provide selective communication between the internal portion of the reservoir and the exterior portion of the unit, the valve assembly including an aperture formed therethrough, a valve seat disposed adjacent the aperture, and a valve member that normally is in sealing engagement with the valve seat, the valve member being of an elastic material which, when subject to deformation through an applied force, is separated from the valve seat to allow passage of fuel through the aperture.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
A fill valve for a lighter having a reservoir for containing a supply of fuel therein, a fill port communicating with said reservoir and adapted to receive a charging apparatus therein for introducing fuel into said reservoir, said fill port having an inwardly facing valve seat surface adjacent its inner end, a resilient and flexible valve means associated with said fill port, said valve means including a poppet head positioned adjacent said valve seat surface of said fill port and normally in sealing engagement therewith, a base ring spaced from said poppet head and connected to said fill port, and a plurality of longitudinally projecting flexible posts connecting said base ring with said poppet head and forming apertures between said posts whereby introduction of a charging apparatus flexes said posts and displaces said poppet head away from engagement with said valve seat and allows the introduction of fuel into said reservoir through said fill port and said apertures formed between said flexible posts.
Claim 2
Dependent Claim
163 words
A fill valve for a lighter having a reservoir for containing a supply of fuel therein, a fill port communicating with said reservoir and adapted to receive a charging apparatus therein for introducing fuel into said reservoir, said fill port having an inwardly facing valve seat surface adjacent its inner end, a resilient and flexible valve means associated with said fill port, said valve means including a poppet head positioned adjacent said valve seat surface of said fill port and normally in sealing engagement therewith, a base ring spaced from said poppet head and connected to said fill port, and a plurality of longitudinally projecting flexible posts connecting said base ring with said poppet head and forming apertures between said posts whereby introduction of a charging apparatus flexes said posts and displaces said poppet head away from engagement with said valve seat and allows the introduction of fuel into said reservoir through said fill port and said apertures formed between said flexible posts.
Claim 3
Dependent Claim
50 words
A fill valve means as claimed in claim 1 and further characterized in that said fill port includes a projecting tubular portion, a first internal bore, a second internal bore located adjacent said first end of said fill port, and a counterbore ledge portion joining said first and second bores.
Claim 4
Dependent Claim
26 words
A fill valve means as claimed in claim 2 and further characterized in that said second bore is of a smaller diameter than said first bore.
Claim 5
Dependent Claim
27 words
A fill valve means as claimed in claim 1 and further characterized in that said posts are circumferentially spaced about said base ring and said poppet head.
Claim 6
Dependent Claim
34 words
A fill valve means as claimed in claim 1 and further characterized in that said base ring has a chamfered diametrical bottom surface, a forwardly projecting flange top surface, and a central internal bore.
Claim 7
Dependent Claim
58 words
A fill valve means as claimed in claim 1 and further characterized in that the length of said posts are such that when inserted and positioned in said fill port, said posts are sufficiently stretched so as to achieve positive pressure between the poppet head of said valve means and the valve seat surface of said fill port.
