19-NOV-2004 12:32PM FROM-Wynnes pattm attornuys 61 7 33421292 T-63B P-005 F-839 0 o A DISPOSABLE FILTER MEANS FOR SMOKING 0 4 FIELD OF INVENTION The present Invention relates to smoking and smoking devices. The present Invention has particular but not exclusive application to disposable accessories and 00 oo parts for pipe and cigarette holders.
Cc- BACKGROUND OF THE INVENTION 0 I' When smoking tobacco from either a pipe, cigarette holder or cigarette, the smoke includes nicotine, moisture, tar and other burnt tobacco byproducts. The pipe and holder usually includes a filter In the stem to limit the amount of burnt byproducts being Inhaled by the smoker. With the pipe and holder, the elongate stem also assists In limiting the amount of burnt byproducts reaching the smoker, because the smoke loses heat and the suspended waste changes from a gaseous phase to a solid or liquid phase and consequently is trapped by the filter.
With time, the waste byproducts clog the pipe preventing smoke from passing through the Internal passage. Consequently, the pipe and cigarette holder require regular cleaning. The cleaning of pipes and cigarette holders sl a laborious task repeated on a regular basis. Furthermore, the cleaning of pipes and cigarette holders usually leaves some waste thereby contaminating subsequent smoke passing through the stem and lessening the enjoyment derived from smoking.
In addition, the area Immediately in communication with the exit portal of the buring chamber is often burnt as a consequence of the high temperature of the smoke reducing the ability of the area to filter the smoke. Eventually the pipe or COMS ID No: SBMI-01005140 Received by IP Australia: Time 13:36 Date 2004-11-19 22-SEP-2006 13:03 From:WYNNES PAT&TM FTT 0733421292 To:0262837999 PA4 -2- Va holder must be replaced because of the damaged area adjacent the burning chamber.
C)
SThese problems are an ongoing source of frustration to smokers as c-effective filtering of the smoke is reduced. Where filtering is reduced over a period of time, the smoker's health can be adversely affected. As well, the 0 0 regular ongoing requirement to clean the pipes and holders before a person c) can enjoy having a smoke often turns the person away from using such smoking devices.
OBJECT OF THE INVENTION It is an object of the present invention to provide an alternative smoking filter means that overcomes at least in part one or more of the abovementioned problems.
SUMMARY OF THE INVENTION In one aspect the present invention broadly resides in a disposable receiving member for use within a pipe or holder to receive smoke from a burning chamber or area and collect waste from passaged smoke and other end products.
