Filter with both conventional and scented filtration

Abstract

A multi-component filter for tobacco smoke and the like comprises a mouthpiece section and two filter sections respectively containing conventional filtration material and scented filtration material in the form of porous scented paper adapted to disguise the odor of the smoke with a fresh clean odor. The sections are telescopically assembled with small spring clips co-operating with annular grooves for releasable connection of the same.

1 . A multi-component filter for tobacco smoke and the like comprising at least two filter sections arranged substantially in alignment with each other for the sequential flow of smoke there through in series, one of said filter sections containing conventional filtration material adapted to remove resin and harmful toxins from the smoke and tending to absorb the foul odor of the smoke, and the other filter section containing a scented filtration material adapted to disguise the odor of the smoke with a fresh smelling fragrance, said filter sections being detachably connected together so as to be opened for the removal and replacement of the filtration materials. 
     
     
         2 . A multi-component filter for tobacco smoke and the like as set forth in  claim 1  wherein a mouth piece section is included, and wherein the mouthpiece and filter sections comprise three parts with at least two of the parts detachably connected together and with the two filter sections arranged downstream of the mouthpiece. 
     
     
         3 . A multi-component filter for tobacco smoke and the like as set forth in  claim 1  wherein a first filter section adjacent the mouthpiece contains an activated carbon filter. 
     
     
         4 . A multi-component filter for tobacco smoke and the like as set forth in  claim 3  wherein a second filter section downstream of the first filter section contains at least one thin porous filter element permeated with a substance which provides a pleasant odor, and which in turn disguises the odor of the tobacco. 
     
     
         5 . A multi-component filter for tobacco smoke and the like as set forth in  claim 2  wherein the second filter section contains a stack of scented sheets of porous scented paper of the type employed in disguising the odor of fabric in a clothes dryer, the sheets being arranged for the flow of smoke there through in series. 
     
     
         6 . A multi-component filter for tobacco smoke and the like as set forth in  claim 1  wherein a membrane which is pervious to smoke but impervious to filtration material is disposed between the filter sections. 
     
     
         7 . A multi-component filter for tobacco smoke and the like as set forth in  claim 3  wherein two (2) membranes which are pervious to smoke but impervious to filtration material are disposed respectively between the mouthpiece section and the two filter sections. 
     
     
         8 . A multi-component filter for tobacco smoke and the like as set forth in  claim 1  wherein membranes which are pervious to smoke but impervious to filtration material are disposed between the filter sections and at the discharge end of the filter. 
     
     
         9 . A multi-component filter for tobacco smoke and the like as set forth in  claim 1  wherein the filter sections are telescopically inter-engaged at their opposite end portions with a releasable snap connection means securing them in assembled relationship. 
     
     
         10 . A multi-component filter for tobacco smoke and the like as set forth in  claim 9  wherein the releasable snap connection means comprises at least one small spring clip member on one filter section and a co-operating annular groove on the other filter section.
