Device for active and passive extinguishing of a cigarette

Abstract

A cigarette extinguishing device, including a tubular fluid receptacle configured to be disposed within a filter of a cigarette, the fluid receptacle having enclosed therein sufficient fluid to extinguish the cigarette, the fluid being under pressure from compressed air within the fluid receptacle, a diaphragm disposed at an end of the tubular fluid receptacle, the diaphragm being configured to be ruptured by at least one of pressure and heat and being more susceptible to pressure and heat than side walls of the tubular receptacle, and a tube connected to the diaphragm and extending through a tobacco region of the cigarette until a distal end of the cigarette, wherein, when the diaphragm is ruptured, the fluid flows from the fluid receptacle via the tube to a burn region of the cigarette, thereby extinguishing the cigarette.

1 . A cigarette extinguishing device, comprising:
 a tubular fluid receptacle configured to be disposed within a filter of a cigarette, said fluid receptacle having enclosed therein sufficient fluid to extinguish said cigarette, said fluid being under pressure from compressed air within said fluid receptacle;   a diaphragm disposed at an end of said tubular fluid receptacle, said diaphragm being configured to be ruptured by at least one of pressure and heat and being more susceptible to pressure and heat than side walls of said tubular receptacle; and   a tube connected to said diaphragm and extending through a tobacco region of said cigarette until a distal end of said cigarette,   
       wherein, said tubular fluid receptacle comprises a syringe including a compressed spring configured to withstand pressure applied by said fluid in said fluid receptacle, said compressed spring being connected at one end thereof to said diaphragm; and pressure applied by a smoker to said filter of said cigarette causes said compressed spring to be released, thereby rupturing said diaphragm and releasing said fluid to flow via said ruptured diaphragm and via said tube to a burn region of said cigarette, thereby extinguishing said cigarette.

         4 . (canceled) 
     
     
         5 . The device of  claim 1 , wherein said diaphragm is configured to be ruptured by elevated burn temperature in the vicinity of said diaphragm, resulting in release of said compressed spring; and
 as a result of rupturing said diaphragm and due to release of said compressed spring, said fluid in said tubular fluid receptacle is injected through said diaphragm and said tube to said burn region.   
     
     
         6 . (canceled) 
     
     
         7 . A method for fabricating a cigarette, the method comprising:
 inserting a tubular fluid receptacle into a cigarette filter, such that said fluid receptacle extends from the proximal area of said filter, through the length of said filter and into a portion of a tobacco region of said cigarette, at the center of said filter;   filling said tubular fluid receptacle with a fire-extinguishing fluid while compressing air within said fluid receptacle, such that said compressed air applies pressure to said fluid within said fluid receptacle;   placing a diaphragm at a distal end of said tubular fluid receptacle, said diaphragm configured to be ruptured by at least one of pressure and heat, said diaphragm being more susceptible to pressure and heat than side walls of said tubular fluid receptacle; and   connecting a tube to said diaphragm distally to said fluid receptacle, such that said tube extends through said tobacco region of said cigarette and enables, when said diaphragm is ruptured, passage of said extinguishing fluid from said fluid receptacle to a burn region of said cigarette thereby to extinguish said cigarette, the method further comprising inserting a compressed spring into said tubular fluid receptacle in addition to said fluid, said compressed spring being configured to withstand pressure applied by said fluid in said receptacle and being connected at a distal end thereof to said diaphragm, wherein pressure applied to said filter results in release of said compressed spring and in rupturing of said diaphragm, thereby releasing said fluid in said fluid receptacle to flow via said ruptured diaphragm and said tube to said burn region regardless of the length of said cigarette when said diaphragm is ruptured.

         9 . (canceled) 
     
     
         10 . The method of  claim 7 , wherein placing a diaphragm comprises placing a diaphragm configured to be ruptured by exposure to elevated temperature caused by burning, such that when said diaphragm is ruptured said compressed spring is released and said fluid is injected through said diaphragm and said tube to said burn region.
