Definitions

  • This invention relates to a device for the purification of tobacco smoke, and more specifically a cigarette holder having means for filtering tobacco smoke before it is inhaled.
  • the raw cottom is essentially absorbent for the condensed residues, not a filter, since the smoke flow path provides for only limited penetration of the absorbent by the smoke, and not for the through flow of the smoke through the absorbent medium.
  • the long, restricted passageway for the smoke makes suctional resistance of the pipe or cigarette holder very high, even when not clogged by condensed deposits which deposit in the spiral passageway rather than be absorbed by the absorbent.
  • the cigarette holder or pipe stem is simply provided with a hollow chamber through which the smoke flows from the cigarette or the bowl of the pipe to the mouthpiece, that chamber, in use, serving to house two longitudinally spaced filter elements constructed of rolled wads of filter paper.
  • a narrow passageway is provided communicating between the socket which receives the cigarette, or pipe bowl, as the case may be and the filter chamber, likewise resulting in adiabatic compression of the smoke as it leaves the socket and before it enters the filter chamber.
  • Yet another similar construction showing another narrow passageway is shown in US ⁇ A ⁇ 2,644,464.
  • the present invention seeks to provide an extremely simple filter-type cigarette holder, but which is highly effective in the removal of noxious substances such as tar and nicotine from the tobacco smoke, and makes use of a combination of features including the discovery that tissue paper, such as that sold under the Registered Trade Mark: Kleenex, is a particularly effective filter medium for tobacco smoke. That taken in combination with other features of the cigarette holder of this invention, in particular, the provision for adiabatic expansion and simultaneous cooling of the smoke substantially directly as it leaves the cigarette, and without any intervening compression before it passes through the tissue paper filter, contribute to a highly effective, yet cheap and simple, filter-type cigarette holder.
  • the cigarette holder comprises at one end, a socket for receiving a cigarette, and, at the other end, a mouthpiece having an axial passageway therethrough for the passage of smoke from the cigarette when received to said socket into the mouth, and located between said socket and said mouthpiece a filter chamber comprising a tubular member providing an internal cylindrical chamber extending between the socket and the mouthpiece, the internal diameter of said chamber being greater than the diameter of said socket, whereby smoke entering said chamber from the socket undergoes adiabatic expansion, and located within said chamber a filter member constituted by a wad of paper folded and removably inserted axially into said chamber, wherein (i) the tubular member defining the filter chamber is constructed of a heat conducting metal, (ii) the socket opens directly into the filter chamber which has a diameter greater than that of the socket whereby smoke leaving the socket is adiabatically expanded directly into the filter chamber without any intervening compression and thereby undergoes two-fold cooling by virtue (a) of said adiabatic
  • the holder comprises a mouthpiece (1) which is a sliding fit with a tubular filter chamber (3) constructed of metal and provided on its external surface with cooling fins (2) and at the end remote from the mouthpiece with a socket (5), which in Figures 1 and 2 serves to receive a cigarette (6).
  • the socket (5) is provided with an internal throat (9) leading into the filter chamber (3) which is of an enlarged internal diameter as compared with the throat (9) and which therefore provides for the adiabatic expansion of the smoke as it enters the filter chamber from the cigarette (6) without any substantial degree of intervening compression.
  • This adiabatic expansion of the smoke causes some initial cooling of the smoke, which is further assisted by the external cooling fins on the filter chamber.
  • cooling fins can be dispensed with and/ or the filter chamber can be constructed of a plain metal tube or of another suitably heat-conducting synthetic material, although perhaps with some concurrent reduction in condensation.
  • Typical dimensions for the filter chamber (3) are a length of 30-50 mm and an inside diameter of 10-20 mm.
  • the cooling/filter chamber is filled internally with a filter element (4) constructed of loosely folded tissue or other similar paper, and as will be seen, the filter element substantially occupies the whole of the internal volume of the chamber as a single element, and acts both as an absorbent for condensed residues in the tobacco smoke and as a filter.
  • the filter element can simply comprise 1 or 2 sheets of tissue paper, e.g. Kleenex, loosely folded upon itself and inserted axially into the chamber prior to fitting the mouthpiece. Using this arrangement, i.e.
  • tissue paper both as a filtration and absorbent medium coupled with the adiabatic expansion and simultaneous external cooling of the smoke as it passed through the filter medium, noxious substances in the smoke are both condensed and absorbed by the tissue with the result that the smoke emerging from the mouthpiece is extremely clean and purified.
  • a further advantage of the present invention is that no special filtration. media or filter cartridges are needed.
  • the filter can be constructed from any conveniently available tissue paper, e.g. a Kleenex tissue. The cost of replacement is therefore virtually nil.
