FIG. 3 is a schematic partial cut-away view showing a resting state and a fire extinguishing state, respectively, of a different embodiment of an apparatus for extinguishing a cigarette according to an embodiment of the teachings herein.

  The present invention, in some embodiments, relates to the technical field of cigarettes, and more specifically to a method and apparatus for preventing fire damage caused by a smoker discarding a lit cigarette.

  Reference is made to FIGS. 1A and 1B, which are schematic partial cut-away views showing one embodiment of an apparatus for extinguishing a cigarette according to embodiments of the teachings herein, each showing a rest state and a fire extinguishing state. The embodiment of FIGS. 1A and 1B provides active and passive fire extinguishing of cigarettes based on the pressurized release of fire extinguishing liquid (also referred to simply as liquid).

  As can be seen in the drawings, the cigarette 10 having the filter 11 and the tobacco region 12 has a tubular liquid receptacle 14 provided in the filter 11. The tubular liquid receptacle 14 is typically less than 3 mm in diameter and is sized to match the length of the particular cigarette filter 11. In general, the tubular liquid receptacle 14 is arranged in the center of the filter 11 about 0.5 cm from the proximal end of the filter 11 so that the proximal end of the tubular liquid receptacle 14 is hidden in the filter 11 and the tip. The part extends into the tobacco area 12 by about 0.5 cm.

  The tubular liquid receptacle 14 may be inserted into the filter 11 during manufacture of the cigarette 10, or may be inserted into the filter 11 after the filter has been made. The tubular liquid receptacle 14 is arranged so as not to prevent the smoker from inhaling the burning tobacco. Tubular liquid receptacle 14 may be formed of a suitable material with a suitable thickness, but in some embodiments is made of nylon with a thickness of about 0.5 mm. The tubular liquid receptacle 14 is sealed with a diaphragm 15 as described later.

  Tubular liquid receptacle 14 has liquid 16 therein, the volume of which is sufficient to extinguish the cigarette as soon as the liquid enters the cigarette combustion zone, for example 0.05-0.2 ml, Or about 0.15 ml. The liquid 16 in the tubular liquid receptacle 14 may be any suitable liquid, such as water, potassium bicarbonate, sodium bicarbonate, or any suitable liquid. The liquid 16 is in the tubular liquid receptacle 14 so that the pressure in the tubular liquid receptacle 14 is higher than atmospheric pressure and the liquid 16 can be pushed out of the tubular liquid receptacle 14 to the tip of the cigarette 10 in response to the operation of the fire extinguishing mechanism. Air 18 is being compressed and injected into the tubular liquid receptacle 14. The pressure reached in the tubular liquid receptacle 14 is calculated at room temperature and pressure based on the ideal gas equation of state well known in the art. In some embodiments, the air pressure within the tubular liquid receptacle 14 is in the range of 2-3 atmospheres when filled. In some embodiments, when compressed air 18 applies pressure to liquid 16 and the pressure in tubular liquid receptacle 14 is released, compressed air 18 pushes liquid 16 distally toward the burning region of cigarette 10. In addition, compressed air 18 is provided proximate to liquid 16 within tubular liquid receptacle 14. In some embodiments, the compressed air 18 can apply sufficient pressure to the liquid 16 and at the same time does not over-pressurize the tubular liquid receptacle 14, and the wall of the tubular liquid receptacle 14, the filter 11 or the cigarette 10. The compressed air 18 occupies approximately 25% of the volume of the tubular liquid receptacle 14 so that pressure does not leak from elsewhere.

  The diaphragm 15 provided at the distal end of the tubular liquid receptacle 14 and sealing it is generally conical in shape, and when sufficient pressure and / or heat is applied to the diaphragm 15, the diaphragm 15 ruptures and becomes tubular. It is sensitive to pressure and heat so as to relieve the pressure in the liquid receptacle 14. In some embodiments, the diaphragm 15 is made of a very thin nylon, such as, for example, about 0.1 mm thick nylon, and is made of a material that is thinner than the tubular liquid receptacle 14. Depending on the thinness of the diaphragm 15 formed of nylon, an increased pressure on the tubular liquid receptacle 14 or diaphragm 15 or an elevated temperature near the diaphragm 15 such as the temperature in or adjacent to the burning area of the cigarette may result in The diaphragm 15 is ruptured. Because the diaphragm 15 is made of a material that is thinner than the tubular liquid receptacle 14, the increased pressure on the tubular liquid receptacle 14 results in the diaphragm 15 rupturing prior to damaging the tubular liquid receptacle 14.

  A hollow tube 19 is provided distally on the diaphragm 15 and extends from the diaphragm 15 through the tobacco region 12 toward the end of the cigarette 10. The hollow tube 19 is usually finished at a short distance from the tip of the cigarette 10, such as about 0.5 cm from the end of the cigarette, so that the hollow tube 19 is not visible from the tip of the cigarette 10. In some embodiments, the hollow tube 19 is connected to the distal end of the tubular liquid receptacle 14 or the distal end of the diaphragm 15. In general, the hollow tube 19 is manufactured so that the liquid 16 can flow through it without being absorbed by the tobacco in the tobacco region 12. Thus, when the diaphragm 15 is ruptured, the liquid in the tubular liquid receptacle 14 passes through the diaphragm 15 and flows through the hollow tube 19 to the burning area of the cigarette and extinguishes the burning area.

  In some embodiments, the hollow tube 19 is hollow from the leaf tobacco used by any cigarette manufacturer in the manufacture of cigarettes because the presence of the hollow tube 19 in the tobacco region 12 does not affect the flavor or aroma of the cigarette. In order to be able to manufacture the tube 19, it is formed by the same leaf tobacco as the leaf tobacco in the tobacco region 12, but is formed by leaf tobacco that is denser and / or more compressed than the leaf tobacco elsewhere. In some embodiments, the hollow tube 19 is formed of paper similar to that used to wrap cigarettes. However, the hollow tube 19 may be formed from any non-toxic material that can prevent liquid from being absorbed by the tobacco in the tobacco area 12.

  In use, the cigarette 10 can be actively extinguished by movement by a smoker or passively extinguished without human involvement.

  If the smoker wishes to actively extinguish the cigarette 10 and cannot find a suitable place to extinguish an ashtray or the like, the smoker applies pressure to the center of the filter 11 as shown in FIG. 1B. You may spend it. The pressure applied to the filter 11 increases the pressure in the tubular liquid receptacle 14, resulting in rupture of the diaphragm 15 and discharge of the liquid 16 from the tubular liquid receptacle 14 into the hollow tube 19. Under the pressure exerted by the compressed air 18, the released liquid reaches the burning area of the cigarette 10 and extinguishes the cigarette regardless of the length of the cigarette at the time of extinguishing. In this way, the smoker can immediately extinguish the cigarette 10 with a movement using only one hand, and the cigarette can be prevented from being discarded while being burned with a risk of fire.

  When the cigarette burns out and the combustion region reaches the region of the filter 11, the diaphragm is ruptured by excessive heat near the diaphragm 15. Due to the force that the compressed air 18 exerts on the liquid 16, the liquid 16 is released from the tubular liquid receptacle 14, injected into the hollow tube 19, and flows from there to the combustion area of the cigarette 10, resulting in active by the smoker. Without having to extinguish a cigarette, the cigarette is automatically extinguished on a self-factor basis.

  Reference is made to FIGS. 2A and 2B, which are schematic partial cut-away views showing one embodiment of an apparatus for extinguishing a cigarette according to another embodiment of the teachings herein, each showing a rest state and a fire extinguishing state. The embodiment of FIGS. 2A and 2B provides active and passive fire extinguishing of cigarettes based on the release of liquid under a force applied to a compression spring.

  As can be seen in the drawings, the cigarette 20 having the filter 21 and the tobacco region 22 has a tubular liquid receptacle 24 provided within the filter 21. The tubular liquid receptacle 24 is generally less than 3 mm in diameter and is sized to match the length of the particular cigarette filter 21. Generally, the tubular liquid receptacle 24 is positioned in the center of the filter 21 about 0.5 cm from the proximal end of the filter 21 such that the proximal end of the tubular liquid receptacle 24 is hidden within the filter 21; The tip extends into the approximately 0.5 cm tobacco area 22.

  The tubular liquid receptacle 24 may be inserted into the filter 21 during the manufacture of the cigarette 20, or may be inserted into the filter 21 after the filter is made. The tubular liquid receptacle 24 is arranged so as not to prevent the smoker from inhaling the burning tobacco. Tubular liquid receptacle 24 may be formed of a suitable material with a suitable thickness, but in some embodiments is made of about 0.5 mm thick nylon or a suitable plastic. The tubular liquid receptacle 24 is sealed by a diaphragm 25 as will be described later.

  Tubular liquid receptacle 24 has liquid 26 therein, and its capacity is sufficient to extinguish the cigarette as soon as the liquid enters the cigarette combustion zone, for example 0.05-0.2 ml, Or about 0.15 ml. The liquid 26 in the tubular liquid receptacle 24 may be any suitable liquid, such as water, potassium bicarbonate, sodium bicarbonate, or any suitable liquid. Further, a compression coil spring 27 is provided in the vicinity of the liquid 26 and the diaphragm 25 in the tubular liquid receptacle 24 and is compressed by the pressure of the liquid 26. In some embodiments, the proximal end of the compression coil spring 27 is provided within the tubular liquid receptacle 24 about 1 mm from the proximal end of the cigarette 20. The button 28 is connected to the proximal end of the compression coil spring 27 and releases the compression coil spring 27 when pressed. In some embodiments, the distal end of the compression coil spring 27 is connected to the proximal end of the diaphragm 25 such that the tubular liquid receptacle 24, the compression coil spring 27, and the diaphragm 25 together form an injector or syringe.

  The diaphragm 25, which is provided at the distal end of the tubular liquid receptacle 24 and seals it, is generally conical in shape, and when sufficient pressure and / or heat is applied to the diaphragm 25, the diaphragm ruptures and compresses. It is sensitive to pressure and heat so that the coil spring 27 is released so that the liquid 26 can be released from within the tubular liquid receptacle 24. In some embodiments, the diaphragm 25 is made of a very thin nylon such as, for example, about 0.1 mm thick nylon. Depending on the thinness of the diaphragm 25 made of nylon, the pressure applied by the release of the compression coil spring 27, or the elevated temperature near the diaphragm 25, such as the temperature in or adjacent to the burning area of the cigarette 20, will result in The diaphragm 25 is ruptured.

  A hollow tube 29 is provided distally on the diaphragm 25 and extends from the diaphragm 25 through the tobacco region 22 toward the end of the cigarette 20. The hollow tube 29 is usually finished at a short distance from the tip of the cigarette 20, eg, about 0.5 cm from the end of the cigarette, so that the hollow tube 29 is not visible from the tip of the cigarette 20. In some embodiments, the hollow tube 29 is connected to the distal end of the tubular liquid receptacle 24 or the distal end of the diaphragm 25. In general, the hollow tube 29 is manufactured so that the liquid 26 can flow through it without being absorbed by the tobacco in the tobacco region 22. Thus, when the diaphragm 25 ruptures, the liquid in the tubular liquid receptacle 24 passes through the diaphragm 25 and flows through the hollow tube 29 to the burning area of the cigarette, extinguishing the burning area.

  In some embodiments, the hollow tube 29 is hollow from the leaf tobacco used by any cigarette manufacturer to produce the cigarette, as the presence of the hollow tube 29 in the tobacco region 22 does not affect the flavor or aroma of the cigarette. In order to be able to manufacture the tube 29, it is formed by the same leaf tobacco as the leaf tobacco of the tobacco region 22, but is formed by leaf tobacco that is denser and / or more compressed than the leaf tobacco elsewhere. In some embodiments, the hollow tube 29 is formed of paper similar to that used to wrap cigarettes. However, the hollow tube 29 may be formed from any non-toxic material that can prevent the liquid from being absorbed by the tobacco in the tobacco region 22.

  In use, the cigarette 20 can be actively extinguished by operation by a smoker or passively extinguished without human involvement.

  If the smoker wishes to actively extinguish the cigarette 20 and cannot find a suitable place to extinguish an ashtray or the like, the smoker may press the button 28 as shown in FIG. 2B. Good. The pressure applied to the button 28 releases the compression coil spring 27 and then ruptures the diaphragm 25 so that the liquid 26 is released from the tubular liquid receptacle 24 into the hollow tube 29. Under the pressure exerted by the released compression coil spring 27, the discharged liquid reaches the burning area of the cigarette 20 and extinguishes the cigarette regardless of the length of the cigarette at the time of extinguishing. In this manner, the smoker can immediately extinguish the cigarette 20 with a movement using only one hand, and the cigarette can be prevented from being discarded while being burned with a risk of fire.

  When the cigarette 20 burns out and the combustion region reaches the filter region, the diaphragm is ruptured by excessive heat near the diaphragm 25 and the compression coil spring 27 is released. Due to the force exerted on the liquid 26 by the released compression coil spring 27, the liquid 26 is released from the tubular liquid receptacle 24, injected into the hollow tube 29 and flows from there to the combustion area of the cigarette 20, resulting in The cigarette is automatically extinguished on a self-factor basis without requiring the smoker to actively extinguish the cigarette.

  In both the embodiment of FIGS. 1A and 1B, and in the embodiments of FIGS. 2A and 2B, the extinguished cigarette can be disposed of in any trash without the need for an ashtray or the ash dropping from the cigarette edge. It is understood that you can. The volume of liquid in the tubular liquid receptacle is sufficient to completely extinguish the cigarette even with a large amount of ash left on the edge of the cigarette, and the cigarette can be discarded without causing a fire hazard .
