METHOD AND SYSTEM OF A MACROSCOPIC PERIMETRIC SCANNING BEAM LOCATING UP TO SIX DIFFERENT DISTINGUISHABLE MATERIAL STRUCTURES

摘要

An ashtray sponge consists of a hard fabric (1), in the interior of which a thick aromatic gel is arranged (2). The hard fabric retains the gel, without entrapping it, the gel flowing out through the fabric of the sponge only when the sponge is pressed by a lit cigarette. Advantage of the invention is that by using this sponge, the unpleasant smell of a cigarette is masked, when the cigarette is pressed on that.
