DE202004008336U1 - Outer filter for lit side of cigarette has inner tubelet pushed into lit cigarette and connected with outer casing, both items being perforated - Google Patents

Abstract

The outer filter for the lit side of a cigarette has an inner tubelet (2) pushed into the lit cigarette and connected with an outer casing (1), both items being perforated (1a,2a). The inner tubelet is encased in a heat-resistant, air-permeable filter unit (3). The space between the outer casing and the inner tubelet is filled with an exchangeable filter filling (4), preferably active carbon. The outer casing is enclosed by an air-permeable material (5), preferably cigar-colored. The inner tubelet is enclosed by an inner cap (6). Two pins (8) are fitted on a closure cap (7) bayonet closure. On closure the pins can be fitted into two slit apertures on both sides, inserted into the outer casing and then rotated.

Description

Smoking cigarettes is refrained from from harmful to health Inhaling the filtered cigarette smoke also from other dangers and inconvenience neither accompanied by the normal cigarette filter even more Cigarette tips with filter function can be prevented.

Part of the smoke from the Burning of the cigarette occurs; is not smoked by inhales the normal cigarette filter but reaches it unfiltered into the environment, this much more toxic part of the smoke is subsequently emitted by inhaled and works directly from others and from the smoker himself become even more harmful to health than the cigarette smoke that both the normal cigarette filter as well as going through the smoker’s lungs with their filtering effect before it gets into the environment. Another danger goes from Carelessly dropped cigarettes from, for example, the person can fall asleep while smoking. Moreover there is unpleasant pollution from cigarette ash.

The object of the invention is; the smoker and his fellow man in front of unfiltered cigarette smoke as well as the risk of fire and pollution from cigarette ash to protect.

With the invention it is achieved that no unfiltered smoke gets into the environment, that the Fire risk is minimized because the combustion inside the heat-resistant filter happens so the glow of the cigarette does not come in direct contact Outside Has.

The polluting cigarette ash remains above out inside the external filter and can be targeted and complete to be disposed of.

An advantageous embodiment of the Invention is presented in claim 1.

A possible embodiment the invention is based on the

1 and 2 explained. Show it:

1 External filter long ago in cross-section view of the wire 2 an advantageous bayonet lock for the external filter

In the 1 is an already lit cigarette in the inner tube ( 2 ) of the external filter, the inner tube ( 2 ) and the outer sleeve ( 1 ) that are connected to each other are perforated ( 1a ) and ( 2a ) and allow unimpeded air supply to burn the cigarette when smoking on the normal cigarette filter.

The inner tube ( 2 ) is in a thin, heat-resistant and air-permeable filter element ( 3 ) made of glass wool, for example. This filter element ( 3 ) leaves the fine-grained filter filling ( 4 ) for example from activated carbon not into the perforation ( 2a ) of the inner tube and partially filters out the tar that forms during combustion. The main filter effect is the fine-grain filter filling ( 4 ), the activated carbon, for example, filters out the smoke particles very effectively. The perforated outer sleeve ( 1 ) is made of an air-permeable fabric ( 5 ) preferably in a cigar color and does not let the filter fill through the perforation ( 1a ) the outer sleeve.

The external filter is intended for repeated use, the replacement of the filter filling ( 4 ) is through the bayonet lock (view A of the 2 ) the removable cap ( 7 ) enables. According to view A, the 2 the cap turned until the two pins ( 8th ) on the sealing cap ( 7 ) attached and into the opening slot ( 1b ) are inserted, pulling out the sealing cap ( 7 ) enable.

The inner cap ( 6 ) closes the inner tube and, thanks to its cone shape, enables the external filter to be refilled with the filter filling without any problems. If you take the inner cap ( 6 ) from; so you can use the inner tube ( 2 ) clean thoroughly with a thin, round brush. The ashes in the inner tube ( 2 ) remains after the smoking process, can be easily disposed of by tapping the external filter. If the burning cigarette is placed in the external filter, it will go out in a period of time that allows smoking, but does not allow the cigarette to continue to glow uncontrollably. Even the hot glow of the cigarette only comes into contact with heat-resistant materials inside the additional filter, which significantly reduces the risk of fire.

Claims (1)

External filter for the glow side of the cigarette characterized in that the inner tube ( 2 ) into which the lit cigarette is inserted; connected to the outer sleeve ( 1 ) both perforated ( 1a ) and ( 2a ) are the inner tube ( 2 ) is with heat-resistant, air-permeable filter element ( 3 ) envelops the space between the outer sleeve ( 1 ) and inner tube ( 2 ) is with exchangeable filter filling ( 4 ) preferably filled with activated carbon, the outer sleeve ( 1 ) is made with a breathable fabric ( 5 ) preferably cigar-colored, the inner tube ( 2 ) with an inner cap ( 6 ) closed on the sealing cap ( 7 ) of the bayonet catch are two pins ( 8th ) attached, which when closed in the two slot openings on both sides ( 1b ), in the outer sleeve ( 1 ), inserted and then rotated.
