(Cl. 131--171) The present invention relates to a smoking-device, and its main object is to provide a smoking-device which enables the smoker to obtain the enjoyment of the tobaccosmoke whilst the necessity of lighting the tobacco in a pipe or in the form of cigars, cigarillos or cigarettes is dispensed with.

Another object of the invention is to provide a smoking device which supplies to the user the full quantity of smoke and prevents the loss of a part of the smoke. Still another object of the invention is to provide a smokingdevice which enables the smoker to interrupt smoking at will and restart it at any desired moment.

Moreover the present invention has for its object to provide a smoking-device which makes smoking more hygienic. In order to achieve these objects the smokingdevice according to the present invention comprises a container for compressed tobacco-smoke and means operative by a sucking action of the smoker for causing the smoke to flow out of the said container.

Thus the principally novel characteristic of the smoking-device according to the invention is in the first place the fact that the tobacco-articles to be sold will no longer contain tobacco, but they will directly contain the desired portion of tobacco smoke.

The known tobacco-products have the disadvantage that when once they are lit they will continue to burn down even while the tobacco-smoke is not enjoyed. Consequently in practice a considerable part of the tobacco is lost to the smoker. Moreover the usual way of smoking has the disadvantage that the smoker must light the tobacco and his mouth and teeth come into direct contact with the tobacco.

On the contrary the present invention provides for tobacco-smoking-devices which are ready for use, without any lighting of the tobacco, as a result of the fact that any kind of pure tobacco-smoke or tobacco-smoke treated by natural or artificial additions or filtered or wholly or partly artificially produced tobacco smoke is stored and preserved in any kind of packings for later enjoyment.

The storing of the tobacco-smoke is effected in such a way that any kind of tobacco-smoke produced by industrial combustion of any kind of tobacco is stored under pressure in smoke-cartridges or smoke-packings. To this end combustion-chambers are utilized in which the tobacco is slowly and gradually burnt under an accurate regulation of the heat-influence.

The thus produced smoke may be altered by the addition of certain desired media and may be pressed through filters in order to remove undesired materials as for in stance nicotine, arsenic, tar or acids from the smoke. By

the addition ofchemical or natural materials the smoke may moreover be flavored in the desired way. Thus it will be possible to change the smoke at pleasure, and the smoke may be dehydrated by means of water-separators.

Moreover it will be possible to create a wholly or partly artificial tobacco-smoke by the application of certain chemical materials instead of tobacco, or any mixture of 2,830,597 Patented Apr. 15, 1958 other natural materials, which have an effect equal or similar to the flavor of tobacco-smoke and which in the form of smoke-products or gases may be less harmful or even beneficial to health.

The necessary effective pressure for storing up the smoke in the smoke-packings is determined in accordance with the desired quantity of smoke to be preserved, the capacity of the packings and the thickness of the walls of the latter. Thus the smoke-cigarettes manufactured according to the present invention may for instance contain a quantity of smoke of one or more cigarettes. It will be possible to preserve the smoke of several cigarettes in a single container as the smoking device according to t. e present invention enables the interruption of smoking at any desired moment. In order to define the quantity of smoke to be stored up in a single packing in practice one could start from the fact that burning one gram of tobacco produces about two liters of smoke at normal atmospheric pressure and temperature and that usually the known cigarettes vary in weight from 1 to 1.5 grams.

The devices according to the present invention present many important advantages. The awkward and dangerous use of matches or lighters which makes smoking expensive, is omitted. Consequently on using the devices according to the present invention smoking will be possible without any diliiculty in a motor-car, in a bedroom and even in rooms and buildings where a risk of fire or explosion exists, whilst also in the open air smoking will always be possible irrespective of the weather conditions.

The smoker will be enabled to obtain the full pleasure of the whole portion of tobacco-smoke which is at his disposal. Moreover all kinds of residues of tobaccoproducts, as Well asthe tobacco ashes themselves will be removed and ash-trays will become superfluous. Any direct contact between the mouth and teeth of the smoker and the tobacco is prevented and smoking is much more hygienic. With respect to the user of cigarettes the advantage is obtained that it will no longer be possible to inhale the smoke of burning paper.

A further object of the invention is to provide for smoking-articles, which in the well-known form of cigars, cigarettes and the like contain the desired tobacco-smoke and which are adapted to give out the same at the will of the user. Still another object of the invention is to provide for smoke-packings destined for filling a tobaccopipe, which are adapted to the shape of the pipe-bowl.

The smoking-devices according to the invention may beprovided-with filters. Moreover they may be arranged in such a Way that they will only 'allow the smoke to escape when the smoker exercisesa sucking action Consequently it will not be necessary to use the smoke completely once the container is opened because the smoker may interrupt smoking at will and may restart it at any desired moment.

The invention will now be further elucidated with refer-- ence to the accompanying drawings, in which some em bodiments of smoking-devices according to the invention are shown.

Figure 1 is a partial sectional view of a smoking-device according to the invention provided with a tobacco-smokecartridge which has the shape of a normal cigarillo or cigar, the smoke-cartridge being shown in a position, only partly screwed into the smoking-device.

Figure 2 shows a similar device in which the smokecartridge is fully inserted and in its position of use;

Figure 3 shape of a cigarette.

Figure 4- shows an embodiment of a smoking-device which has the shape of a tobacco-pipe, adapted to con-. tain smoke-packings of such a shape as to readily fit in the interior of the pipe-bowl.

is a similar embodiment of a smoking-device adapted for the use of smoke-cartridges which have the The device according to Figures 1-3 consists of three parts which are screwed together, to wit the mouth-piece 1, the middle-piece 2 and the container 5, the mouth-piece 1 being provided with an external screw-thread 3, which fits in the internal screw-thread 4 arranged in the middlepiece 2. The smoke-cartridge 5 is screwed into the middle-piece 2 by means of an external thread 6 fitting in the internal thread 7 of the said middle-piece. The mouth-piece 1 and the middle-piece 2 may be manufactured out of an artificial resin, the smoke-cartridge may be made of a transparent artificial resin as for instance Plexiglas (polymethyl methacrylate) or a similar material.

The mouth-piece 1 has been provided with a boring 8 extending through the whole length of the same through which boring the smoke can be sucked. Within the middie-piece 2 a cavity 9 is arranged in which cavity a light compression spring It) as Well as a somewhat conically shaped loosely fitting valve stop 11 are mounted, the said valve stop ending in a conical needle.

In Figure 1 there is shown in what manner the smokecartridge 5 is inserted in the smoking-device. To this end the mouth-piece 1 is wholly screwed into the middlepiece 2 so that a pressure is exercised on the spring 10. On the other end the bottom of the cartridge 5 is pressed against the needle-point of the valve-stop 11 so that the spring 10 is put under pressure from this side too.

When thereafter the smoke-cartridge is still further screwed into the middle-piece 2 the needle-point of the valve-stop 11 pierces the bottom of the cartridge 5, as is shown in Figure 2. As a result of the pressure of the spring 10 the valve-stop 11 with its conical needle is moved into the opening thus formed in the bottom of the cartridge and thus closes this opening formed by the needle in such a way, that the smoke, which is stored in the cartridge 5 under pressure is prevented from streaming out.

By unscrewing the mouth-piece 1 partially out of the middle-piece 2 (see Figure 2) the spring 10 and thereby the needle of the loosely-fitting valve-stop 11 are discharged just to such a degree that the smoke is enabled to flow out of the cartridge 5, when on the other end of the valve the smoker exercises a sucking action on the mouthpiece 1. The smoke then flows through the opening in the bottom of the cartridge, passes along the needle and the conical valve stop, which fits with a slight clearance with respect to the surrounding wall, into the cavity 9 and further through the boring 8 into the mouth of the smoker.

If the smoker wants to interrupt smoking, the mouthpiece is again screwed into the middle-piece 2 so that the spring 10 is again put under pressure and thereby the valve-stop 11 with its needle-point is pressed into the opening in the bottom of the cartridge. Thus the conical needle will close the opening, moreover the conical stop 11 itself will act as a closing member.

If, on unscrewing the mouth-piece 1 from the middlepiece 2 and on discharging the spring 10 thereby, the needle of the valve-stop 11 should appear not to come out of the opening by itself because it is pinched in the opening of the cartridge-bottom the needle can be loosened easily by unscrewing the smoke-cartridge 5 somewhat from the middle-piece 2.

In the embodiment according to Figure 4 the needle is fixedly connected with a pin 13 extending through a small slot arranged in the wall of the pipe, and enabling the needle to be withdrawn from the smoke-packing 12 if the needle should become pinched in the opening in the packing.

In order to enable the smoke-packing to be easily taken out of the pipe-bowl the height of the packing 12 is somewhat greater than the height of the pipe-bowl itself. Both the smoke-packing and the cavity of the pipe-bowl are executed in an unsymmetrical form in order to prevent the packing from being turned out of its original position.

, vided with an axial boring therethrough and at one end ending in a screw-threaded portion, a tubular container containing compressed tobacco-smoke and at one end ending in a screw-threaded portion, and a cylindrical middle member provided at both ends with screw-threads in engagement with the screw threads of the mouth-piece and of the container respectively, said member being provided with means for controlling the flow of the tobaccosmoke out of the container through said middle member into said axial boring of said mouth-piece, said middle memberbeing provided with a central boring consisting at one of its ends of a cylindrical cavity in communication with the axial boring of said mouth-piece and at its other end of a small cylindrical boring extending the entire length of the middle member towards the bottomwall of said container, said means for controlling the flow of smoke from said container through said middle member towards said mouth-piece comprising a valve-stop arranged in said cylindrical cavity and a pressure-spring mounted between said valve-stop and said mouth-piece and pressing said valve-stop in the direction of said container, said valve-stop at its other end terminating in a conical needle extending through said cylindrical boring of said middle-member towards the bottom wall of said container and being adapted to pierce said bottom wall as a result of the pressure of said spring when said mouthpiece, middle member, and container of the smoking device are screwed together, the pressure of said spring being such that the needle is kept in place until a sucking force is exerted upon the mouthpiece.
