Definitions

  • This invention relates to a means for filtering the smoke in cigars, cigarettes and the like by means of an adjustable filter which may be compressed to provide maximum filtration or partially compressed to effect a lesser filtration of the smoke.
  • the present invention offers an improvement over known methods of efiecting wet filtration of tobacco smoke, and is especially directed toward a means for governing the extent of such filtration, to suit the preference of the individual smoker.
  • FIG. 1 is a perspective view of the filter device of the present invention attached to a cigarette;
  • FIG. 2 is a cross-sectional view of the two parts of the housmg
  • FIG. 3 is a cross section taken on line 33 of FIG. 1;
  • FIG. 4 is the view of FIG. 3 after compression of the projecting portion of the filter rod to force the same into the end of the housing.
  • FIG. 1 there is shown a filter device attached to cigarette 11, with housing 12 severed at 13 to create an annular member 14 surrounding the end of the filter member 15.
  • FIG. 2 shows housing 12 and member 14 in cross section.
  • FIG. 3 projecting filter member 15 and filter member 16 are shown within opposite ends of the housing 12 and disposed therebetween, sponge material 17 and hollow bodies 18 partially filled with fluid 19.
  • FIG. 4 shows the cross section of FIG. 3 after compression of the filter to force filter member 15 into the housing 12, rupturing the fluid containers and releasing their contents into sponge 17 to cause expansion thereof.
  • the filter is activated by the removal of the annular member 14 and pressure of the filter rod at the smokers end of the filter, to force said rod into the housing, thus by such force causing the rupture of the fluid containers and the release of their contents into the adjacent sponge material which, being compressed and absorbent, is caused to expand when moistened and thereby fills the space previously occupied by the dry sponge and the fluid containers.
  • the projecting filter rod is pressed all the way into the housing so that the outer end of the filter rod is flush with the end of the housing.
  • the tobacco rod may be pressed into the housing only part of the way so that the sponge material is less closely packed.
  • cutting means are suggested for severing the filter housing at points opposite and equidistant from the center of the double length filter, and other cutting means for severing the housing and the filter rod at the center point between the two halves of the double length filter.
  • the suggested cutting of the filter housing leaves an annular part 14 thereof severed from the housing 12 but surrounding the outer end of the filter rod 15.
  • Such annular member serves to protect the device from premature or inadvertent compression of the filter rod.
  • the severed annular member 14 is removed and the projecting end of the filter rod is pressed telescopically into the housing, thus rupturing the fluid containers l8 and releasing the contents 19 thereof into the sponge material 17.
  • Continued pressure upon the filter rod reduces the space available to accommodate the moistened sponge, thereby increasing the filtering effectiveness of said sponge, as above described.
  • a filter for smoking devices having a substantially cylindrical housing and disposed within each end thereof a conventional filter rod, and disposed between and in contact with said filter rods, compressed absorbent, expansible sponge material, and at least two rupturable containers having a fluid content, and longitudinally spaced from each other within said sponge material, the improvement of having one of said filter rods slidably fitted within one end of said cylindrical housing and projecting beyond the outer and thereof, whereby said one filter rod may be controllably pushed inwardly selective distances to vary the amount of compression on said sponge material to selectively control the rupturing of said containers in sequence.
