Definitions

  • the object of this invention is an impact filter for tipped cigarettes, which assists in affording much more effective retention of the noxious ingredients contained in tobacco smoke, preferably tar, an agent which is considered to be highly cancerigenic.
  • filters of tipped cigarettes act by absorption.
  • Said filters are formed by a porous mass which adopts the same diameter as the cigarette and is envelopped by a sheet which, at the same time as it functions as a decorative element, assists in the incorporation of the mentioned filter in the cigarette.
  • figure 1 shows a perspective view of the filter incorporated in a cigarette, which is represented by dotted lines.
  • Figure 2 is an exploded perspective view of the filter, to provide a perfect illustration of all the parts forming it.
  • Figure 3 is likewise an exploded perspective view of the chamber located in the interior of the filter, inside which the impact filtering takes place, thus being the essential feature of the invention.
  • figure 4 is a section of the mentioned chamber incorporated in a cigarette, the trajectory of the smoke which passes through it being indicated with arrows.
  • the impact filter is essentially formed by a principal member, this being a chamber 1 which adopts a diameter similar to that of the cigarette.
  • the lower base of the mentioned chamber is formed by a coupled plate 2, which has orifices 3 of a very small diameter uniformly distributed over its periphery. Provision has been made in the centre of the upper base 4 of the chamber for a downward tubular orifice 5, the skirt whereof penetrates the inside thereof considerably.
  • the mentioned chamber can be incorporated in the cigarette accompanied by one or two portions 6 and 7 of absorbent material, the chamber and portions being connected by a wrapping 8, so that the filter presents the conventional aspect of those incorporated by tipped cigarettes commonly available on the market.
  • the mentioned chamber could be incorporated in the cigarette without the components specified in the preceding paragraph, but it has to be taken into account that it will have to be made of a somewhat hard and, moreover, preferably transparent material, so that the smoker interested therein may check the effectiveness of the retention of tar in the chamber by simply disassembling the unit formed by the filter and releasing the chamber from the portions adjacent thereto.
  • the impact experienced by the smoke inside the mentioned chamber makes a large portion of the tar which it contains become deposited in film form on the inner contour thereof, but preferably, and forming a considerable mass, on the inner surface of the lower base. Additionally, the adjacent portions 6 and 7 of absorbent material also retain tar, even if in a minimal proportion, as usually occurs, for which reason it can be considered that the role they play in the filter assists and supplements the greater retaining effectiveness of the central chamber which acts by impact, although the filtering portions 6 and 7, above all the one occupying the latter place, have further been provided so that the smoker does not note the hardness of the plastic chamber on putting the cigarette to his lips and, consequently, so that the tact presented by the cigarette does not differ at all from the tipped ones available on the market.
