Definitions

  • the present invention relates to pipes, cigarettes, cigars and other devices used for smoking. It relates more particularly to tobacco replacement products and to equipment making it possible to control the smoke-air ratio.
  • the HEW report states, on page 74, that "the effects of nicotine in doses absorbed by a smoker (1 to 2 milligrams per inhaled cigarette) are relatively weak".
  • Another unpleasant characteristic of smoke relates to the effect of air pollution and, more particularly, to the inhalation of tobacco smoke by people near the smoker in an enclosed environment.
  • the side effects exerted on non-smokers have been observed in particular on bartenders and waitresses who work long hours in poorly ventilated bars and cafes. These drawbacks have only been partially remedied by using mechanical and electrostatic filtration machines comprising fans.
  • US-A-4 303 083 (Burress, jr) proposes the use of a similar method for the administration of volatile drugs.
  • the invented devices can only be used near a source of electric current. They are inconvenient to use. Their presentation, handling and operation are too different from the standard smoking device for them to behave as acceptable replacement items.
  • FR-A-787679 describes a pipe with a separate combustion chamber placed in the ordinary pipe furnace. It makes it possible to smoke the tobacco placed in the combustion chamber in the usual way, which is always open on the pipe of the nozzle and also makes it possible to associate with the smoke thus obtained the vaporized emanations which emerge from a circular compartment surrounding the combustion chamber but isolated from it and containing the product that one wishes to vaporize additionally.
  • the opening between the duct and the end piece is not adjustable and the harmful effects cannot be reduced as can be done with a pipe constructed according to the principles of the present invention.
  • the present invention provides means for completely eliminating the harmful inhalation of tar and smoke carrying toxic products, by limiting the absorption by the smoker, to purified nicotine, aromatic products simulating tobacco and to antidote metabolites. .
  • Any inconvenience affecting the non-smoker who is nearby can be eliminated by replacing the tobacco with a combustible material based on aerated cellulose, with a pleasant odor.
  • the smoking devices according to the invention can be produced in various configurations.
  • the air intake channel can take the form of a chimney extending in the center of a pipe stove, a cigar or a cigarette.
  • the tobacco or the combustible material which replaces it is maintained in a cupular chamber whose peripheral walls are surrounded by a series of channels converging towards the nozzle.
  • the main object of the invention is to provide a smoking device which completely eliminates the inhalation of tar and other smoke carrying toxic materials.
  • Another object of the invention is to provide a device or kind precipitated having the appearance, and providing the taste and the feeling of a pipe, a cigarette or a cigar of common type. while retaining all the pleasant physiological effects following the admission of nicotine.
  • Another object of the invention is to provide means making it possible to reduce the discomfort caused to non-smokers being in the immediate vicinity of a smoker in an enclosed space.
  • the invention also aims to improve the quality of substances inhaled by the smoker, by incorporating elements antidotes to the combination of purified nicotine and harmless aromatic compounds simulating tobacco.
  • This first embodiment comprises a smoking pipe 1, the head 2 of which receives a cup-shaped insertion element 4.
  • This element is provided with a covering rim 8.
  • a hole 11 provided at the bottom of the cup 4 is closed by a spout 12 when the cup is forcibly engaged towards the bottom of the furnace 5 of the pipe.
  • the level of the cup 4 inside the furnace 5 can be adjusted by screwing the cover 9 on the thread 19 on the side of the head of the pipe 2.
  • the cover 9 has a series of peripheral holes 18 cooperating with a similar series of holes 17 made on the crown of the pipe head 3.
  • the cup 4 is preferably made of ceramic, zinc, carbon fiber alloy, or any other material which can be compressed or molded to the desired shape and which can withstand the temperature of combustion of tobacco or similar substances.
  • the outer walls of the cup are preferably porous and are crenellated in order to facilitate the dispersion of heat inside the gap 13.
  • the inner walls of the cup 4 are striated by a series of vertical cylindrical grooves 10 converging towards hole 11 at the bottom. These grooves have openings which are very narrow and which prevent the pieces of tobacco from entering the interior. They are designed to ventilate the contents of the cup, to facilitate the combustion of tobacco or substitute material.
  • the volatile and sublimable substances which will vaporize when the cup is heated, permeate the porous surface of the outer walls.
  • These substances are chosen to smell, give taste and behave like tobacco would when burning. They include nicotine, aromatics that impart the taste and smell of tobacco, and antidote metabolites such as niacinamide. These substances which tend to vaporize or sublimate at lower temperatures are impregnated on the vertical zones of the outer walls 14, while the less volatile components are preferably impregnated in the concave zones 15, between the slots.
  • the device is used as follows.
  • the cup 4 is raised to the upper position, which opens the hole 11, but closes the air passage through the holes 17 and 19.
  • the interior of the cup is filled with tobacco or other combustible material.
  • the pipe is lit in the usual way, the user sucking air through tobacco or the like to activate combustion. Once the pipe is lit, the cup 4 is turned clockwise, to a lower position, until the hole 11 in the bottom is closed and the air is allowed to flow through. through holes 17 and 18.
  • the heat of combustion vaporizes the tobacco-simulating substances and nicotine, which are inhaled by the smoker, producing the same pleasant sensations as for inhaling tobacco smoke, but without exposing the smoker or its vicinity to the harmful effects of tar and other by-products existing in tobacco smoke.
  • the cup 4 can also be adjusted to an intermediate position allowing the user to draw in a mixture of tobacco smoke and air carrying substances. It should be noted that this air will be heated to a temperature close to that of tobacco smoke, via the heat conducting walls of the cup 4.
  • the mouthpiece 22 is composed, in the same way as an ordinary cigarette, of a short tubular element 23, intended to observe saliva and avoid turbulence, and of a cork envelope 29, applied above the layer of cigarette paper 28.
  • the end piece 22 also comprises a funnel 25 tapering towards a chimney 26 extending over the length of the cigarette.
  • the tobacco 27, or other combustible material is placed around the chimney 26, inside the paper envelope 28.
  • the chimney is made of a non-combustible material, such as ceramic, carbide or graphite alloy, or other sheet, and is composed of several short sections 24 connected end to end and maintained by a bonding compound 30.
  • the latter can be a fuel or a compound, such as zinc oxide, melting or softening at a temperature higher 400 ° C.
  • Each section has a plurality of internal fins 31 configured so as to provide, in the chimney 26, good dispersion of the heat produced by the combustion of tobacco.
  • volatile substances simulating tobacco are applied inside the chimney.
  • the most volatile components are applied to the surface of the fins 31 and the least volatile, on the walls of the chimney, in the space 32 between the fins.
  • the terminal section 33 is provided with holes 34 which facilitate the lighting of the cigarette, while allowing the smoker to suck the tobacco smoke through the chimney 26.
  • each section 33 , 24, from the chimney separates from the next one and falls with the tobacco ashes.
  • Peroxide may be added to tobacco, or a substitute, to facilitate combustion.
  • FIG. 8 represents a variant of the configuration of the walls of the chimney 26.
  • the most volatile substances are deposited in the convex zones 36 of the inner wall of the chimney cup, while the least volatile substances are deposited in the concave zones 35 which are exposed to a higher temperature.
  • the concave zones 36 on the outer wall of the chimney 26 behave like grooves which supply the air necessary to activate the combustion. as in the previous embodiment described.
  • FIGS 9 and 10 illustrate a third embodiment 40 of the invention, having the appearance of a cigar or a cigarette.
  • This smoking device comprises a hard envelope of ceramic or other non-combustible material.
  • the tobacco 45 is compressed in a chamber 44 having star-shaped walls and arranged concentrically inside the main envelope 41.
  • the end piece 42 contains a tubular element intended to absorb saliva and to avoid turbulence 43 , and is in direct communication with the channels 46 which extend between the outer casing 41 and the combustion chamber 44.
  • a small screen 47 is arranged at the open end of the combustion chamber 44 to retain the tobacco and the ash inside.
  • the tobacco simulating substances are deposited inside the channels 46.
  • the most volatile substances are deposited against the internal walls of the outer envelope 41, and the least volatile, against the outer wall of the combustion chamber 44.
  • a few holes are provided in the screen 47 near the combustion end of the cigarette in order to facilitate ignition.
  • This embodiment has the additional advantage of retaining the ashes inside, thus not requiring the use of an ashtray. The entire device can be discarded after use.
  • the cup-shaped insert 4 of the first embodiment can also be of the lost type.
  • the insert 4 can also be constructed according to the sectional configuration shown in FIG. 9 or, according to a variant, the crenellated outer walls can be surrounded by a cylindrical envelope, in order to protect the deposit of volatile substances.
  • FIGS. 11 to 13 show a second embodiment 50 of a pipe according to the invention.
  • a receptacle 54 is engaged in the air duct 52 of the pipe.
  • This receptacle has an internal channel 55 provided with a tapped entry oriented upwards.
