Description

 Smoking device, in particular tobacco pipe

DESCRIPTION

The present patent application relates to a smoking device, in particular in the form of a tobacco pipe, consisting of a mouthpiece and a head attached to it and provided with a smoke channel, in which a head bore receiving a tobacco compact is arranged.

State of the art:

Conventional smoking devices, in particular tobacco pipes with the features of the preamble of claim 1, are generally stuffed with loose tobacco and, for this purpose, have a head or pipe bowl with a head bore, the bottom region of which continuously merges into the side wall of the head bore with a curved section. The bottom area is either rounded or designed in the manner of a round bowl with a tapering central area. When filling the smoking device and the subsequent tamping process, essentially the entire head bore is filled with tobacco crumbs, with an optimal filling aiming for a tobacco density gradient with a hard-stuffed top area and a soft-stuffed bottom area of the tobacco volume.

During the smoking process, the tobacco volume is burned more or less uniformly over the entire cross-sectional area of the head bore, so that the combustion taking place within the head heats the head made of wood or other suitable materials to a considerable extent.

As a further prior art, attempts have been made to pre-press tobacco as individually manageable smoke portions with a spherical, conical or approximately cylindrical shape and to use them in conventional pipes (DE-GM 90 03 671). If with such insert bodies could not achieve optimal smoking results, this is because the pre-pressed tobacco body tends to disintegrate when inserted into the head bore of the pipe bowl or is at least severely deformed and then must be replanted in the head bore

Task:

The invention has for its object to provide a smoking device, in particular a tobacco pipe, which is very easy to use even by inexperienced smokers, in particular is easy to fill, can be smoked without a tamping process and is easy to clean

This object is achieved by the characterizing features of claim 1. Advantageous developments of the invention are specified in the subclaims

It is considered to be the essence of the invention to design the cross section of the head bore such that the side wall of the head bore is essentially cylindrical, ie appears in the cross-sectional representation as a straight line and then merges into the bottom region of the head bore in such a way that a Prefabricated, essentially cylindrical tobacco compact is essentially completely absorbed by the cylindrical region of the head bore, a collecting space remaining below the tobacco compact in the bottom region of the head bore, which is delimited by a cut surface, ie the underside of the tobacco compact

By designing a head of the smoking device in this way, it is possible to insert prefabricated cylindrical tobacco pellets with a diameter that corresponds to the inside diameter of the head bore into the head bore and to smoke there without further tamping that the tobacco compact does not fall too deep into the head bore, but occupies a position that is as defined as possible Advantageously, the transition of the cylindrical part of the side wall in the bottom area should be angled. If one speaks of angular, there should be a definable, pronounced transition angle which separates the side wall of the head bore relatively clearly from the bottom region of the head bore. The transition angle is not necessarily designed in the manner of a defined edge; the transition angle can also be rounded slightly. The smoke channel, which leads to the mouthpiece, opens into the center of the base area, which is advantageously of a flat conical shape. The opening of the smoke channel is not acted upon by the tobacco compact, so that due to the free space below the underside of the tobacco compact, the air sucked in is uniformly collected, so that the tobacco compact is essentially flowed through with its entire cross section. A very uniform smoking of the tobacco compact is thereby made possible. Clogging of the opening is also avoided by the distance between the underside of a compact and the smoke channel mouth.

The cone angle of the base area should advantageously be greater than 100 °. The transition angle between the side wall and the floor area should be approximately 100-135 °, depending on how high the head should be.

Advantageously, a tobacco compact with a cylindrical shape with a flat top and bottom and a covering, in particular made of a tobacco leaf and / or tobacco foil, is used in the smoking device. As a result, the tobacco compact is kept in good shape on the one hand, and on the other hand, the smoking process within the head takes place very evenly through the covering. It has been shown when smoking that the casing remains more or less and the smoking process is carried out essentially inside the casing, so that the smoking device only needs to be knocked out slightly after the smoking process in order to ensure adequate cleaning. There is also no fear that the side wall area of the head bore will burn off too much, since the embers are not in direct contact with it. It is therefore not necessary to scrape burnt tobacco residue out of the head and the mouth of the To clean the smoke channel in the bottom area of the head bore. Only tobacco juices have to be removed from the smoke channel with a conventional pipe cleaner

In the smoke-ready state of the smoking device, the casing of the tobacco compact lies against the side wall of the head bore, but only with slight pressure. Due to unevenness in the area of the casing, air sucked in through the mouthpiece during the smoking process can sweep along the outside of the casing of the tobacco compact and through micro-openings of the Entering the wrapper into the tobacco compact This enables very fine flow of air through the tobacco compact with sucked-in air and thus very aromatic smoking

The subordinate claims 20 ff relate to a tobacco compact for use in a smoking device, in particular a tobacco pipe, which is designed in particular according to one of claims 1 to 19. For the present invention it is particularly important that the tobacco compact and that together with it the smoking device used are coordinated with one another as closely as possible. The two objects have a very close functional relationship. Only when the tobacco compact is adapted to the smoking device belonging to it does the desired advantages arise when smoking the tobacco compact in the smoking device according to the invention

First of all, a large adaptation of the tobacco compact to the head bore of the smoking device is significant. The tobacco compact should be able to be smoked in the smoking device without re-plugging, the aim being that the tobacco compact burns evenly after being lit for the first time, provided that the smoker at the mouthpiece smokes the smoking device in the usual way Way on train

The inside of the tobacco compact should consist of pipe tobacco.Tests have shown that pipe tobacco, provided it is placed in a sleeve-like wrapper, is very pleasant and easy to smoke without leaving large residues on the walls of the head bore of a smoking device, which are then scraped out ¬ had to However, it is also possible to use other tobacco. If the inner area of the tobacco compact is formed by compressed tobacco rods that run essentially parallel in the direction of the main cylinder axis of the tobacco compact, the tobacco compact is particularly easy to produce, dimensionally stable and aromatic to smoke.

Claims 23 and 24 relate to size dimensions which have proven particularly advantageous in tests - because they are easy to handle and uniformly wearable.

Due to the features of claim 25, the tobacco compact can be lighted particularly easily without ash falling from the head of the smoking device after lighting.

Claims 26 - 32 relate to features in the area of the casing, its construction and adhesive bonding. These features simplify the manufacture of the tobacco compacts, improve their stability and increase the pleasure of smoking.

The invention is explained in more detail on the basis of advantageous exemplary embodiments in the drawing figures. These show:

First of all, on drawing fig. 1 Referenced The smoking device shown there in the form of a tobacco pipe 1 consists of a mouthpiece 2 and a pipe head 4 attached to it by means of a plug connection 3. Both the mouthpiece 2 and the shaft 5 of the pipe head 4 are penetrated by a smoke channel 6. The smoke channel 6 mouths in the bottom region 9 of a head bore 7, which is provided for receiving a tobacco compact 20

The side wall 8 of the head bore 7 is essentially cylindrical up to the base region 9 of the head bore 7 and goes at an angle, that is to say including a transition angle 10 into the base region 9 of the head bore 7 above. The base region 9 of the head bore 7 has a flat cone shape is more than 100 °. The transition angle 10 between the side wall 8 of the head bore 7 and the adjoining surfaces of the base region 9 is approximately between 100 and 135 °

The smoke channel 6 leading to the mouthpiece 2 flows into the center of the bottom region 9 of the head bore 7, a slight displacement of the mouth 12 of the smoke channel 6 towards the mouthpiece 2 being ascertained on account of the diameter of the smoke channel 6

In the following, reference is made to drawing 2. The tobacco compact 20 shown there in the head bore 7 has a cylindrical shape with an essentially flat upper side 21 and lower side 22. Furthermore, it has a covering 23 made of a tobacco leaf or a tobacco foil, which tightly encloses tobacco particles located inside the tobacco compact 20 The casing 23 of the tobacco compact 20 lies in the smoky Finished state of the tobacco pipe 1 on the side wall 8 of the head bore 7, wherein air sucked in through the mouthpiece 2 during the smoking process sweeps along the outside of the casing 23 of the tobacco compact 20 and enters the tobacco compact 20 through the micro opening of the casing 23, not shown in detail what is indicated by arrows 25 The burning of the tobacco compact 20 runs essentially within the casing 23 of the tobacco compact 20, so that after the smoking process there are still remains of the casing 23, between which there is loose ash. These tobacco residues and the remains of the casing 23 can be removed by simply tapping on the tobacco pipe 1

From drawing 2 it is also clear that the radially outer lower edge 26 of the tobacco compact 20 is seated on the radially outer region of the bottom region 9 of the head bore 7 and the center of the bottom region 9 is not acted upon by the underside 22 of the tobacco compact 20 ¬ compacts 20 a collecting space 27 is formed, in which smoke emerging from the tobacco compact 20 below is collected and directed into the smoke channel 6

The modified embodiment of the tobacco pipe 31 shown there is designed as a so-called pocket pipe and has a mouthpiece 32, a plug connection 33, a pipe head 34, a smoke channel 36 and a then arranged head bore 37 with side wall 38 and base area 39 on The tobacco pipe 31 has an elongated shape, the pipe head 34 is approximately trapezoidal in the vertical section and extends with its narrow trapezoidal side 30 via the plug connection 33 into the mouthpiece 32 via the top 50 of the mouthpiece 32 and the top 51 of the pipe head 34 essentially a merging flat surface. As regards the dimensions of the tobacco pipe 1 according to FIG. 3, the head height of the pipe head 34 is approximately 20-30 mm, its overall length is approximately 90-130 mm. The inside diameter of the head bore 37 is approximately 10 - 18 mm The total depth of the head bore 37 concerns agt about 13 - 18 mm The cylindrical region of the side wall 38 of the head bore 37 extends approximately 10-16 mm deep into the head bore 37 and is delimited at the bottom by the transition angle 10

4 and 5 now show details relating to the tobacco compact 20. In the sectional view according to FIG. 4 it can first be clearly seen that the inner region 60 of the tobacco compact 20 is formed by strand-like tobacco elements or tobacco rod 61 which are essentially parallel to one another in FIG Run in the direction of the cylinder main axis 62

In addition, details relating to the sleeve-like covering 23 can be seen, which, however, are shown in the drawing-like figures 4 and 5 in an exaggeratedly thick manner for reasons of clarity in their layer-like structure. This consists first of all of a double-layered wrapping sheet 70 around which a cover sheet 71 is wrapped An adhesive layer 72 is arranged between the cover sheet 70 and the cover sheet 71, which ensures full-surface adhesion of the cover sheet 71 to the interior areas carrying it. The cover sheet 71 can - but does not have to - be wound helically instead of that shown schematically in FIG full-surface gluing in the area of the sleeve-like covering 23 or the cover sheet 71, a line-like gluing can also be carried out, as shown in FIG. 5

There the cover sheet 71 is initially shown in a helical winding. The edges 75 of the cover sheet 71 are provided with adhesive lines 76 which, of course, are not really visible when such a tobacco compact 20 is viewed because they are on the underside of the cover sheet 71, but for reasons of clarity are graphically represented

Drawing figure 6 corresponds to the essential drawing figure 1, but schematically supporting elements 80 are shown, which in the manner of pegs or ring segment sections protrude into the cross section of the head bore and serve to support the tobacco compact 20 from below
