Abstract

A cigarette holder comprising two parts (1,6), the first part being adapted to receive a cigarette and there being means between the two parts to cause the tobacco smoke moving therethrough to move at a high speed and then to impinge abruptly on a surface which causes the tar in the tobacco smoke to be separated out to be collected in a chamber (9) in a mouthpiece (10) of the holder. <IMAGE>

Description

SPECIFICATION Cigarette holder This invention relates to a cigarette holder.

More particularly, the invention relates to a cigarette holder that is constructed to act as a filter means for separating out a substantial proportion of the tar present in tobacco smoke, before the smoke is taken in by a smoker.

According to the present invention, there is provided a cigarette holder constructed to act as a filter means for separating out a substantial proportion of the tar present in tobacco smoke, the holder being formed as a unitary member having a first part which is hollow and cylindrical and adapted to receive the corresponding end of a cigarette, the inner diameter of said first part being adaptable to the diameter of conventional cigarettes, and second part serving as a filter, said first part being closed by means of a straight stepping at its inner base, an annular neck extending axially from the stepping and being disposed between the holder body and an inner coaxial cylindrical projection connected to the holder body by way of a circular ring near the plane separating the two parts, there being a plurality of apertures associated with that edge of the ring which connects with the cylindrical projection, such apertures extending through the circular ring with an outwards inclination, being of very reduced diameter and producing a substantial acceleration of the smoke so that, in use, the smoke impinges abruptly on the outer wall of the neck forming the perimeter of the projection to cause the tar to be separated out, the second part of the holder extending towards its free end in a flat shape bounding an open chamber to store the tar so deposited.

Thus, the main feature of the holder is that, by causing the tobacco smoke to move at high speed and then impinge abruptly on a surface, the tar, which is of course the basically harmful ingredient of tobacco, is separated out.

Preferably, there are four apertures which are uniformly distributed around the ring.

The tar storage capacity in the second part of the holder is of course considerably greater than corresponds to the tar content of a single cigarette, to make the holder cheaper for the user.

Preferably, the holder is made of plastics which is transparent so that the user can see how the tar deposit chamber gradually fills up, so that he can discard the holder before the tar becomes close to the end of the holder which the smoker places in his mouth.

For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawing, in which: Figure 1 is a perspective view of a cigarette holder according to the invention, and Figure 2 is a longitudinal section through the holder shown in Figure 1.

Referring to the drawing, the holder is formed as a unitary transparent plastics member comprising a first part 1 which is hollow and cylindrical and whose inner diameter is adapted to the diameter of conventional cigarettes and whose open end 2 is wide enough to be engaged in it.

The first part 1 terminates in a straight stepping 3 which closes its space, the same being associated with an annular neck 4 coaxial with the holder body 6, a cylindrical and preferably hollow projection 5 being disposed coaxially in the neck 4 and being closed at its free end and being connected to the holder body 6 around the neck 4 by way of a circular ring 7 which substantially closes the neck 4.

On the annular edge connecting the projection 5 to the circular ring 7 there are four apertures 8 which are disposed at 900 offset from one another and which are inclined outwards at almost 900 to the holder axis, each such aperture serving as a smoke duct. Because the apertures 8 are so narrow, the smoke experiences an abrupt acceleration as it flows through them, with the result that the smoke impinges abruptly on the outer side wall of the neck 4 where, as previously stated, the tar is deposited.

The second part of the holder extends as far as the opposite end of the body in the form of a large flat passage 9, the body also being flattened in the corresponding zone, as can be seen from Figure 1, until terminating in an exit orifice or mouth piece 10 which the smoker places in his mouth.

Both the peripheral neck 4 and the flat passage 9 form the zone where the tar is deposited gradually, the increasing deposit being permanently visible to the smoker because of the transparent plastics used for the holder, so that the same is discarded when the amount of tar deposited makes this seem advisable.
