Definitions

  • a cigarette holder-filter includes a cigarette receiving socket at one end and a mouthpiece at the other end.
  • the interior of the holder includes a fibrous filtering material impregnated with water.
  • the ends of the [52] U.S. Cl. 206/41 R, 53/37 51 rm. Cl B65d 79/00, B65b 3/04 Older are i a manner POkmg Subsm' [58] Field of Search 206/41 R' 53/37 tially the shelf life of the unit and to enable the holder to be filled fully with water.
  • the invention resides in providing a minute pin hole in the seal at the mouthpiece end of the device which enables air which might ordinarily become entrapped in the filter, to escape through the mouthpiece end when the filter is filled with water. Because there are no entrapped air pockets, the interior of the filter may be filled to saturate fully the fibrous plug and may even be filled beyond this amount. After the filter is filled with water the cigarette-receiving end is sealed. While the existence of the minute pin hole may permit a relatively small amount of water to evaporate and escape, the rate of any such escape is so insignificant in relation to the amount of water within the filter device as to still increase substantially the shelf life of the filtering device.
  • a further object of the invention is to provide an improved cigarette filtering device and technique for manufacturing the device which provides a high degree of reliability in impregnation of the device with water while reducing the likelihood of entrapping air within the filter.
  • FIG. 1 is an illustration of a cigarette filter of the type described
  • FIG. 2 is an illustration of the filter in section as seen along the line 22 of FIG. 1;
  • FIG. 3 is an end view of the sealed mouthpiece of the filter.
  • FIG. 1 shows, for example, one of a variety of disposable cigarette filters of the type with which the invention may be employed.
  • filters are described generally in US. Pat. No. 3,137,303 and my aforementioned US. Pat. No. 3,375,920.
  • These filters contain a fibrous material preimpregnated with water.
  • the filter includes an elongated casing 10 formed from a plastic material.
  • the casing has a tapered mouthpiece 12 formed at one end and an annular cigarettereceiving socket 14 at the other end.
  • a cylindrical metal sleeve 16 having an outwardly flared lip 18 is fitted firmly into the cigarette receiving end of the casing 10, with the lip 18 engaging a lip 20 formed on the casing.
  • the sleeve 16 defines the cigarette receiving socket 14 and is proportioned to receive a cigarette in a snug fit.
  • a fibrous material 21 is disposed within the casing rearwardly of the sleeve 16.
  • the completed filter is closed at its socket end with a cap 22 having a continuous sidewall 24 which is closed at the bottom by an integral and continuous dome-like bottom 26.
  • the upper edge of the sidewall 24 is outwardly and arcuately flared to define a lip 28.
  • This lip 28 is spaced from the lip 18 on the sleeve 16 to define a recess 30 of sufficient dimension to permit one to insert a fingernail between these two lips for removal of the cap 22.
  • the cap is formed of a suitable substantially gas impervious plastic material having sufficient flexibility and resilience to permit insertion and removal of the cap with relative ease.
  • polyethylene may be an appropriate plastic material.
  • the mouthpiece end 12 of the device is covered with a removable covering 32 formed of a film of tearable plastic material.
  • the covering 32 may be formed by dipping the mouthpiece end of the easing into a fluid plastic bath a sufficient distance to form the film over the mouthpiece end to enclose fully the mouthpiece.
  • An appropriate material for the covering 32 should be non-toxic easily tearable or removable from the mouth piece end in ordinary use.
  • the covering may be formed from a commercially available material known as Thermi Cote N4 which is principally a mixture of cellulose acetate butyrate and dioctyl phthalate material.
  • the fibrous material and sleeve 16 may be inserted into the casing 10.
  • the mouthpiece end of the casing 10 then is dipped into the plastic film forming material to form the covering 32.
  • a minute pin hole 34 is formed through the covering 32 in communication with the internal passage 36 within the mouthpiece 12.
  • the casing may be filled to the desired extent with water. There is no tendency for air to become entrapped in the filter as the air may escape through the minute pin hole. As a result, it is insured that a sufficient quantity of water will be received in the device.
  • the cap 22 is inserted into the sleeve 16 to seal effectively the interior of the device.
  • the single minute pin hole has no noticeable adverse effect on the shelf life of the filter. In shelf life tests which were conducted, there did not appear to be any adverse effect on the quantity of water retained within the filter. I have found that a pin hole approximately 0030-0040 inch diameter gives quite satisfactory results.
  • the user unseals the ends and then blows through one end of the holder to discharge the excess water contained therein.
  • the cigarette holder then is ready for use with the assurance that the filter material is properly wetted.
  • a cigarette holder construction comprising:
  • a casing having a mouthpiece end and a socket end adapted to receive a cigarette tip
  • volume of fluid disposed within said casing, said volume of fluid being greater than that which is required to impregnate fully said fluid impregnable fibrous mass;
  • a cigarette holder as defined in claim I further comprising:
  • a method of fabricating a cigarette holder as defined in claim 1 comprising:
  • hole is no greater than approximately 0.040 inches in diameter.
