j - tobacco pipe stopper

The innovation relates to closures for tobacco pipes, in particular for covering the open mouth of the pipe bowl.

The use of open-headed tobacco pipes is accompanied by certain well-known disadvantages. After using the pipe, it is not possible for the smoker to put it in his pocket because of the risk of burns stuck without first removing all remaining coal and hot ash. For this purpose are not always suitable objects or facilities are available.

It is similar in certain circumstances not possible to put the pipe down after lighting,

as there is a likelihood of hot charred tobacco and ash being blown by a draft or by the Wind is blown out of the pipe, or there is a risk that the piece of furniture on which the pipe is placed has been scorched. Another complication arises from the fact that there is condensation in the pipe There is tar and moisture leaking from the pipe and clothing or the underlay, on which the pipe has been placed can get dirty.

Main object of the innovation is to provide a closure for a tobacco pipe, which can rapidly and easily be set up, clears the burning tobacco in the pipe immediately seals the pipe bowl effective unverl to the leakage · _-: innten tobacco ash and liquid tar-containing substances to prevent, which closure can also be used universally for tobacco pipes with a variety of external contours and shapes and for a considerable range of sizes.

The solution to the problem according to the innovation is characterized in the claims and described with reference to the drawing; show it:

1 and 2 views in elevation, partly in section, of the tobacco pipe closure according to the invention 1 shows the closure in a preliminary stage when it is placed on a tobacco pipe and FIG. 2 the cap fully placed on the pipe.

As shown in the drawing, the tobacco pipe closure according to the invention on the head of a tobacco

whistle 10 can be arranged. The whistle can be of any of the conventional categories of mic whistles be open minds.

A special feature of the innovation is that any given closure of the previously described Art can be used universally for pipes with heads of different diameters, as well as for Pipe bowls with outer surfaces that are either rough or smooth, and for pipe bowls with outwardly convex surfaces Shaping. The latter are particularly difficult to equip with closures because there is a risk that they emerge through the bulbous design of the pipe bowl. be forced.

Any of the pipe closures described below '] mainly has a pipe head cap, the

is generally designated by 12, and a circumferential jacket,

- which protrudes from the cap and is generally referred to as IM

j is. These elements are made in one piece with each other

and are made of a suitable, essentially air-impermeable, resilient or elastically deformable raw material, such as natural rubber or synthetic Rubber shaped like a pipe slide. Ls las son siel ·, also use various plastics for the intended purpose. When using soldier hangover: alien the closures can easily be mass-produced by compression molding in dies of suitable contour below Can be produced using conventional pressing processes.

The head cap 12 has a central part which is surrounded by a peripheral edge part, from which the latter a uniform jacket protrudes and extends transversely to the head cap cr- ■ i. The middle part of the head cap is open with 3ezug

the circumference of the ana is covered, whereby an anjatz 16 is obtained which protrudes from one side of the central part in the transverse direction. Preferably there are two such central approaches are provided in a symmetrical arrangement, one of which extends inwards and the other outwards with respect to the pipe bowl. This makes the closure fully reversible in its use. In other words, the middle section the head cap is preferably covered with respect to the peripheral edge part so that two opposite, transversely projecting lugs 16 are obtained, one of which from one side of said central part protrudes and the other from the opposite side of the same.

The thick central part of the head cap has at least three Main functions.

First, it stiffens the central portion of the closure so that it can be easily applied.

Second, it helps to hold the cap properly on the bowl of the pipe. This is made possible by that we prevent wrinkling or creasing on the middle part '. Furthermore, it is only necessary to put the enlarged thickened part in the middle of the head, whereupon the closure automatically in its correct position is held.

Thirdly, this makes the closure universally applicable made on pipe bowls that are sizable within a Range of different external diameters, for example between 25 mm and 35 mm (between 1 "and 1 3/8") can be in which range

876 298

the great majority of pipe bowl sizes fall. This is made possible by the fact that around the perimeter of the protruding Areas around an inclined surface 18 is present, which extends over a considerable distance to the outside spreads out to ensure that the inner edge of the pipe bowl with this area over a considerable Range of pipe bowl sizes has contact, such as himself can be seen in particular from FIG.

The jacket m is provided with a thickened outer edge 20. This results in a handle on the outer edge of stiff elasticity. Furthermore, the closure is firmly secured to the surface underneath and is prevents it from shifting or slipping until it is actually intended to be removed.

At the transition point between the head cap 12 and the jacket 11 is a thin, flexible area 22. This connects the jacket with the head cap a flexible connecting portion so that the closure can be easily reversed, i.e. out of the. The position in FIG. 1 can be turned inside out into that of FIG. It also forms a coherent one

Sealing over the entire open area of the pipe bowl, J

Putting the cap on the pipe is very easy.

First, the shutter becomes that shown in FIG

Brought position in which one of the lugs 16 sits in the pipe bowl and the other protrudes outwards.

Then, with an easily executable movement of the fingers, the jacket section 14 is turned around, if it is the

The outer surface of the pipe bowl is covered and elastically encompassed, as shown in FIG. In this position it bears the thickened part 20 for anchoring the closure to the outside of the head, even if the the latter is convex in its contour and is rough and irregular in its design.

The pipe lock according to the innovation therefore results several important functional advantages.

It can be put on easily. After putting it on, it can easily be flipped open. It's universal for Pipes with heads of different internal diameters can be used. He is also J'ir pipes with heads of different outside diameters and designs largely applicable.

In addition, the pipe lock according to the innovation can be used in either of its two positions. After putting it on, it immediately deletes any existing charring Tobacco and effectively prevents the escape of ash, unburned tobacco and substances containing tar. The smoker can therefore put the pipe in his pocket, pack it in different containers or on pieces of furniture without the risk of burns, scratches or stains.
