Title: Smoking device

Description:
FIELD OF THE INVENTION 
     This invention relates to smoker&#39;s devices. 
     BACKGROUND OF THE INVENTION 
     In the past there have been numerous types of smoker&#39;s devices. This invention is of a smoker&#39;s device for use in smoking cigarettes. 
     OBJECTS OF THE INVENTION 
     It has as an object the provision of a tubular body with a one-way valve which permits smoke from the cigarette in the inlet of the tubular body to pass through the one-way valve to the outlet but which does not permit reverse flow. Reverse flow can take place through exhaust ports to which there is connected in fluid connection tubular lengths extending away from the ports and through which the smoke exhausts through a one-way valve which permits fluid flow from the inlet to the outlet and through the outlet through the tubular lengths by valving structure which does not permit a reverse flow. 
     It is another object of this invention to provide a device of the type described which is simple and inexpensive to manufacture and well adapted for the purposes for which it is intended. 
    
    
     DESCRIPTION OF THE DRAWINGS 
     FIG. 1 is a perspective view of the smoking device; 
     FIG. 2 is a top cross-sectional plan view of the device showing the passage of smoke as it is inhaled through said device; and 
     FIG. 3 is a top cross-sectional plan view of the device showing the passage of the smoke as it is expelled through said device. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawings wherein like reference characters designate like or corresponding parts throughout the several views and referring particularly to FIG. 1, there is shown a tubular body 11 having an inlet end 14 and an outlet end 16. There is a one-way valve 18 disposed adjcent the inlet end to open and close part 19. The inlet 14 is sized to nest a cigarette therein in fluid communication and the one-way valve 18 is adapted to permit fluid flow from the inlet 14 to the outlet 16. In the wall of the tubular body there are a pair of oppositely disposed ports 30 and 32. These ports each connect to a length 40 and 42 respectively which terminate at ends 44 and 46 respectively. At each end 44 and 46 there is also provided a one-way valve means 45 and 47 which is adapted to permit fluid flow only in the direction from the outlet 16 through the ports 30 and 32 to exit through the second mentioned one-way valve means 45 and 47 respectively. 
     In this manner a cigarette may be positioned in the inlet and smoke drawn through the device opening the first mentioned one-way valve 14 and passing through the outlet 16. The smoke may be exhausted by blowing through the outlet 16 which will exit through the ports 30 and 32 and respective tubular lengths and one-way valves arranged thereon. The smoke is not permitted to flow back to the inlet 14 by reason of the one-way valve means 18 closing port 19. 
     It is thus seen that there has been provided a novel and not obvious smoker&#39;s device which is useful in smoking and training one to not smoke cigarettes by providing means for minimal inhalation by efficient exhausting structure built directly into the subject device.
