Description

  The present invention relates to a cylindrical smoking aid that covers a cigarette that reduces sidestream smoke during smoking.

  As a smoking aid that suppresses sidestream smoke, Patent Document 1 states that “a coat portion in which a non-combustible substance is coated on a cigarette outer periphery and non-combustible continuously or intermittently along the length direction of the cigarette. A sidestream smoke-reducing tobacco characterized in that an exposed portion serving as an air inlet without a coat portion of the substance is formed (Claim 1); A sidestream smoke-suppressing cigarette (Claim 2) "characterized in that it is provided with a thin moving ring of slidable non-combustible material is disclosed.

  According to the sidestream smoke suppression tobacco described in Patent Document 1, it is possible to reduce the amount of sidestream smoke by restricting the inflow of air into the tobacco, and it is possible to sustain the seed fire by the carbonization phenomenon. As a result, it is possible to improve the longevity of the cigarette, and by covering the coat part to be coated, the amount of ash is reduced and the dispersion of the ash is prevented, so that contamination by the surrounding ash can be prevented. If it is made of metal foil, the metal foil is squeezed and closed, and in addition to preventing dirt due to ash, there is an effect that it can be a simple ashtray (extinguishment) without causing a risk of fire due to embers. Furthermore, it can be set to extinguish naturally in a very short time (within about 1 minute) as long as oxygen is not supplied by suction even if it is left in an ignition state, and it can prevent disasters caused by fires and other types of fire. It is said that it also has an effect.

In addition to the above effects, in addition to the above effects, a position for suppressing sidestream smoke and a position for extinguishing the fire are provided around the outer periphery of the cigarette because a thin moving ring of non-combustible material that can slide along the length of the cigarette is provided. The smoker can arbitrarily set, and if the moving ring is crushed, it can be forcibly extinguished and can be used as an ashtray substitute.
Japanese Patent Laid-Open No. 2000-4863

  However, when the sidestream smoke suppression cigarette described in Patent Document 1 is forcibly extinguished, it is assumed that the coat portion is made of metal foil, and the tip must be closed by squeezing the metal foil. In addition, a thin moving ring made of a slidable non-combustible material is provided, moved to a fire type part, and extinguished by crushing the ring. Therefore, it cannot be re-ignited, and a process of providing a coat part for each cigarette is performed, which is naturally disposable, resulting in complicated and high-cost cigarettes.

  Therefore, the present invention is a simple and low-cost method for reducing sidestream smoke, automatically extinguishing the fire when left unattended, allowing forced fire extinguishment, and enabling reignition. The purpose is to provide ingredients.

In order to solve the above problems, the present invention

Since it is automatically extinguished in a neglected state and can be forcibly extinguished, it has the effects described in the prior art, such as being able to safely clean up after the fire. In addition to these, re-ignition is possible and it can be used repeatedly, so that sidestream smoke can be suppressed and smoking can be enjoyed at low cost.

  By covering the fire extinguishing part with a heat-resistant cover, it is possible to forcibly extinguish smoothly without burning.

  Furthermore, by limiting the total area of the holes with respect to the perforated portion, it is possible to draw patterns such as figures and characters while suppressing sidestream smoke, and to decorate the outer periphery of the cigarette.

  For the purpose of advocating a smoking tool that easily suppresses sidestream smoke at low cost, the extinguishing part 10b having a length of 1.5 to 2.5 cm from the end 2e that completely covers the outer periphery of the cigarette 4 and the extinguishing part 10b A plurality of holes 10c are drilled alternately from the end to the tip 2d, covering the cylindrical body 10 composed of the perforated part 10a thicker than the outer periphery of the fire extinguishing part 10b, and the fire extinguishing part 10b of the cylindrical body 10, and the perforated part 10a This was realized by adopting the configuration of the sidestream smoke suppression smoking tool 9 characterized by comprising the heat-resistant cover 11 having the same thickness as the outer periphery of the stool.

  Hereinafter, the sidestream smoke suppression smoking device according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1: is a side view at the time of use of the 1st Example of the sidestream smoke suppression smoking implement which is this invention. FIG. 2 is an exploded side view of the first embodiment of the sidestream smoke suppression smoking device according to the present invention. FIG. 3 is a rear view of the first embodiment of the sidestream smoke suppression smoking device according to the present invention.

  A sidestream smoke suppression smoking tool 1 according to the present invention includes a cylindrical body 2 and a heat-resistant cover 3. The cylinder 2 covers a fire extinguishing part 2b having a length of 1.5 to 2.5 cm that completely covers the outer periphery of the cigarette 4, and leaves a few millimeters from the end of the fire extinguishing part 2b, leaving a plurality of holes up to the end 2d. 2c consists of perforated portions 2a that are formed alternately, and is a tube that covers the outer periphery of the cigarette. The number of the tip of the cigarette is about 2 to 9 mm, preferably 3 to 6 mm, and more preferably 4 to 5 mm. same as below. The portion protruding from the perforated portion 2a of the cigarette should be such that the cigarette can be ignited, and it does not have to protrude excessively from the perforated portion 2a. This is because if the portion protruding from the perforated portion 2a is 10 mm or more, sidestream smoke cannot be suppressed for a while after ignition, and if the protruding portion is too short, ie, about 1 mm or less, ignition is not easy.

  The inner diameter of the cylindrical body 2 is made slightly larger than the diameter of the cigarette so that the cigarette can be inserted and cannot easily come off. The thickness of the cylindrical body 2 is preferably 1 mm or less, and more preferably 0.5 mm or less. When the cylindrical body 2 becomes thick, the cigarette feels heavy and gives the smoker an unpleasant feeling. Therefore, the raw material of the cylinder 2 should just be a metal and fixed hardness (strength which can be used repeatedly). For example, aluminum that is lightweight and easy to process is suitable.

  As shown in FIG. 2, the cigarette 4 (Caster Mild (registered trademark)) that is usually sold has a total length of about 8.4 cm, a filter portion 4 b of about 2.5 cm, and a diameter of about 0.8 cm. Therefore, in the cylinder 2, more specifically, the fire extinguishing part 2b is about 2 cm from the end 2e, and the perforated part 2a is about 4 cm. The diameter was 0.8 cm + d (very slightly larger).

  Since the fire extinguishing part 2b is located on the filter part 4b side of the tobacco 4 and completely covers the fire extinguishing part 2b, the fire extinguishing part of the burning tobacco reaches the fire extinguishing part 2b. When it is desired to rapidly extinguish the fire, the fire extinguishing part 2b may be slid to the fire type part. It can be extinguished quickly and conveniently, and can be handled extremely safely without any mistakes.

  The perforation part 2a is located in the direction of the combustion part 4a of the cigarette 4 following the fire extinguishing part 2b, and a hole 2c is perforated to expose the combustion part 4a of the cigarette 4 (exposed part 4e). The exposed area of the burning part 4a of the cigarette 4, that is, the total area of the holes 2c, is desirably 60% to 80% with respect to the area of the perforated part 2a.

  If the total area of the holes 2c is lower than 60% with respect to the area of the perforated part 2a, the fire is naturally extinguished during smoking (about 10 to 30 seconds). The suppressing effect is not exhibited. If it is within 60% to 80%, it can be seen that the amount of rising sidestream smoke is also halved visually.

  The hole 2c is pierced with a drill or the like. At this time, burrs are generated inside the pierced portion 2a, so the burrs are removed with a file or the like. In this case, the inner surface of the cylindrical body 2 is filed, so that the inner diameter of the cylindrical body 2 is slightly larger than that of the cigarette 4, and the roughening also has an effect of preventing the tobacco from dropping off.

The heat-resistant cover 3 is a part that covers the fire extinguishing part 2b, picks up ash during smoking, and picks it with a finger when sliding the sidestream smoke suppression smoking tool 1. Therefore, a material having low heat conductivity and not deformed and melted by tobacco fire is selected. For example, Teflon (registered trademark) is suitable. The length may be the same as that of the fire extinguishing part 2b.

The tip of the cigarette 4 is partially protruded from the perforated part 2a. Moreover, the filter part 4b is substantially exposed from the cylinder 2, and lips contact the filter part 4b. In this state, the cigarette is lit and smoked by normal work.

  FIG. 4B shows a state during smoking using the sidestream smoke suppression smoking device 1 according to the present invention. When smoking progresses, the combustion part 4a burns and the fire type 4c advances into the cylindrical body 2, the burned combustion part 4a becomes ash 4d, and the impact remains within the perforated part 2a. Therefore, the ash 4d is not scattered in the smoking place, and the smoking place is not soiled with the ash 4d. Further, the ash 4d can be dropped into the ashtray or the like through the hole 2c by a normal ash tapping operation.

  FIG.4 (C) has shown the state when using the sidestream smoke suppression smoking tool 1 which is this invention, and forcibly extinguishing. The fire type 4c advances to the fire extinguishing part 2b and is extinguished naturally. In addition, the fire extinguishing part 2b is picked with a finger and the fire extinguishing part 2b is slid to the position of the fire type 4c, thereby enabling rapid and forced fire extinguishing.

  In addition, after extinguishing the fire, it is possible to ignite by partially projecting the tip of the cigarette from the cylinder 2 as shown in FIG. Furthermore, in this invention, since intensity | strength is more than fixed, it can equip with another tobacco and can be used repeatedly, and is economical.
