Abstract
Abstract A valve for a cigaret gas lighter is comprised of a flexible gas conduit extending between a nozzle and a gas tank. The flexible gas conduit is pinched or bent to close the conduit. An operating member pinches or bends the gas conduit to close the conduit by a spring. A manually operable lever is provided to open the conduit by removing the operating member overcoming the spring force. In a preferred embodiment of the invention, the conduit is positively opened in addition to removal of the operating member when the gas lighter is to be ignited.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
261 words
A valve means for use in a gas lighter having a gas tank to be filled with liquefied fuel gas, an ignition means located on the gas tank, and a nozzle located close to the ignition means for spouting the fuel gas from the gas tank in front of the ignition means, said valve means comprising a valve conduit connected between the gas tank and the nozzle for making communication therebetween, said valve conduit being made of elastic material and capable of closing its flow path formed therein by operation from outside, a pressing member movable between a closing position to effect upon the valve conduit to close its flow path and an opening position to release the valve conduit to allow the conduit to recover its original form to open the flow path due to its elasticity, means integral with said pressing member for forcing the valve conduit to open when said pressing member is in said opening position, said pressing member comprising a pressing portion for pressing the valve conduit against a fixed face to close the conduit, a valve retaining portion for receiving the valve conduit when the conduit is pressed and closed, and a valve conduit opening portion located adjacent the valve retaining portion for forcing the valve conduit to open, said valve conduit opening portion comprising a pair of walls having a space therebetween slightly smaller than the outer diameter of the valve conduit, and a manually operable actuating lever operable from outside for moving said pressing member between said closing position and said opening position.
Claim 2
Dependent Claim
261 words

Claim 3
Dependent Claim
23 words
A valve means for use in a gas lighter as defined in claim 1 wherein said valve conduit is made of synthetic rubber.
Claim 4
Dependent Claim
292 words
A valve means for use in a gas lighter which consists of a gas tank filled with liquefied fuel gas, an ignition means located on the gas tank, and a nozzle located close to the ignition means for spouting the fuel gas from the gas tank in front of the ignition means, said valve means comprising a valve conduit connected between the gas tank and the nozzle for making communication therebetween, said valve conduit being made of elastic material and capable of closing its flow path formed therein by operation from outside, a pressing member movable between a closing position to act upon the valve conduit to close its flow path in a first direction and an opening position to release the valve conduit to allow the conduit to recover its original form to open the flow path in a second direction substantially perpendicular to said first direction by its elasticity, a manually operable actuating lever operable from outside for moving said pressing member between said closing position and said opening position, and means for forcing the valve conduit to open when said pressing member is in said opening position by pressing the conduit in said second direction, said means for forcing the valve conduit to open being integral with said pressing member, said pressing member comprising a pressing portion for pressing the valve conduit against a fixed face to close the conduit, a valve retaining portion for receiving the valve conduit when the conduit is pressed and closed, and a valve conduit opening portion located adjacent the valve retaining portion for forcing the valve conduit to open, said valve conduit opening portion comprising a pair of walls having a space therebetween slightly smaller than the outer diameter of the valve conduit.
Claim 5
Dependent Claim
292 words
A valve means for use in a gas lighter which consists of a gas tank filled with liquefied fuel gas, an ignition means located on the gas tank, and a nozzle located close to the ignition means for spouting the fuel gas from the gas tank in front of the ignition means, said valve means comprising a valve conduit connected between the gas tank and the nozzle for making communication therebetween, said valve conduit being made of elastic material and capable of closing its flow path formed therein by operation from outside, a pressing member movable between a closing position to act upon the valve conduit to close its flow path in a first direction and an opening position to release the valve conduit to allow the conduit to recover its original form to open the flow path in a second direction substantially perpendicular to said first direction by its elasticity, a manually operable actuating lever operable from outside for moving said pressing member between said closing position and said opening position, and means for forcing the valve conduit to open when said pressing member is in said opening position by pressing the conduit in said second direction, said means for forcing the valve conduit to open being integral with said pressing member, said pressing member comprising a pressing portion for pressing the valve conduit against a fixed face to close the conduit, a valve retaining portion for receiving the valve conduit when the conduit is pressed and closed, and a valve conduit opening portion located adjacent the valve retaining portion for forcing the valve conduit to open, said valve conduit opening portion comprising a pair of walls having a space therebetween slightly smaller than the outer diameter of the valve conduit.
Claim 6
Dependent Claim
23 words
A valve means for use in a gas lighter as defined in claim 3 wherein said valve conduit is made of synthetic rubber.
Claim 7
Dependent Claim
44 words
A valve means for use in a gas lighter as defined in claim 3 or 4 wherein said pressing member presses the valve conduit against a fixed portion to pinch the valve conduit therebetween to close the flow path therethrough in said closing position.
