Spill-proof smoking implement

Abstract

A smoking implement includes a cylindrical container having a sufficient volume of water to act as a filter for ash, resin and unburnt tobacco particles. The container has a mouthpiece at its top end through which smoke can be inhaled. An elongate pipe or stem extends through a side wall of the container. One end of the pipe is adapted to allow smoke to bubble up through the water in the container when in its upright position; the other end of the pipe has a receptacle or cone in which a quantity of tobacco may be burnt. A hollow tapered extension piece is provided in connection with the mouthpiece, and extends some distance into the container. The extension piece ends in a distal opening of reduced size relative to the mouthpiece, and is fitted with a valve member. In the event that the container is knocked over from its upright position the distal opening will be substantially above the water level so that water is inhibited from spilling out of the container through the mouthpiece.

1 . A spill-proof smoking implement of the type that relies on water to filter the smoke prior to inhalation, the smoking implement comprising: 
 a container having a sufficient volume of water to act as a filter for ash, said container having a mouthpiece through which smoke can be inhaled;    an elongate pipe extending through a side wall of the container, one end of the pipe being adapted to allow smoke to bubble up through the water in the container when in its upright position, the other end of the pipe having a receptacle in which a quantity of tobacco may be burnt; and,    a hollow tapered extension piece provided in connection with said mouthpiece and extending into the container, said extension piece ending in a distal opening of reduced size relative to the mouthpiece whereby, in use, in the event that the container is knocked over from it upright position said distal opening will be substantially above the water level so that water is inhibited from spilling out of the container through the mouthpiece.    
   
   
       2 . A spill-proof smoking implement as defined in  claim 1 , wherein said extension piece effectively creates a spilt chamber within the container, a water chamber being formed on the inner side of the extension piece in which the filter water is substantially contained, and on the outer side of the extension piece an air chamber is formed with the mouth piece which is open to atmosphere.  
   
   
       3 . A spill-proof smoking implement as defined in  claim 1 , wherein said extension piece is formed integral with the mouthpiece.  
   
   
       4 . A spill-proof smoking implement as defined in  claim 1 , wherein a valve member is fitted to said distal opening of the extension piece, the valve member being designed to further inhibit leakage of water through the distal opening.  
   
   
       5 . A spill-proof smoking implement as defined in  claim 4 , wherein said valve member is formed with a small lateral aperture that opens to one side of the valve member to allow smoke from within the container to be drawn out through the mouthpiece.  
   
   
       6 . A spill-proof smoking implement of the type that relies on water to filter the smoke prior to inhalation, the smoking implement comprising: 
 a container having a sufficient volume of water to act as a filter for ash, said container having a mouthpiece through which smoke can be inhaled;    an elongate pipe extending through a side wall of the container, one end of the pipe being adapted to allow smoke to bubble up through the water in the container when in its upright position, the other end of the pipe having a receptacle in which a quantity of tobacco may be burnt; and,    a hollow tapered extension piece provided in connection with said elongate pipe and extending into the container, said extension piece ending in a distal opening of reduced size relative to said one end of the pipe whereby, in use, in the event that the container is knocked over from it upright position said distal opening will be substantially above the water level so that water is inhibited from spilling out of the container through the pipe.    
   
   
       7 . A spill-proof smoking implement as defined in  claim 6 , wherein said distal opening of the extension piece extends below the water level in the container.  
   
   
       8 . A spill-proof smoking implement as defined in  claim 6 , wherein said extension piece effectively creates a spilt chamber within the container; on the outer side of the extension piece, within the container, a water chamber is formed in which the filter water is substantially contained, and on the inner side of the extension piece a smoke chamber is formed, with said elongate pipe, that communicates with the receptacle in which tobacco is burned.  
   
   
       9 . A spill-proof smoking implement as defined in  claim 6 , wherein said one end of the pipe does not extend below the water level in the container, even when the smoking implement is in its upright position, so that at no point during normal operation is there any water in the pipe.  
   
   
       10 . A spill-proof smoking implement as defined in  claim 8 , wherein an inside diameter of the extension piece is preferably substantially larger than an outer diameter of the pipe, whereby, in a spill situation, although a small volume of water retained in the distal opening of the extension piece may flow into the smoke chamber, the possibility of any water entering said one end of the pipe is remote.  
   
   
       11 . A spill-proof smoking implement of the type that relies on water to filter the smoke prior to inhalation, the smoking implement comprising: 
 a container having a sufficient volume of water to act as a filter for ash, said container having a mouthpiece through which smoke can be inhaled;    an elongate pipe extending through a side wall of the container, one end of the pipe being adapted to allow smoke to bubble up through the water in the container when in its upright position, the other end of the pipe having a receptacle in which a quantity of tobacco may be burnt; and,    an aperture provided for facilitating evacuation of smoke from the container, said aperture having a normally-closed valve provided therein which can be operated by a user to facilitate evacuation of smoke from the container when needed.    
   
   
       12 . A spill-proof smoking implement as defined in  claim 11 , wherein said valve is in the form of a spring-loaded push button valve, which is opened by applying pressure to the push button.  
   
   
       13 . A spill-proof smoking implement as defined in  claim 11 , wherein said valve is mounted in a side wall of the container using a suitable rubber seal that is air tight and water tight during normal use of the smoking implement, and is designed so that the valve can be easily removed during disassembly for cleaning.  
   
   
       14 . A spill-proof smoking implement as defined in  claim 11 , further comprising a first hollow tapered extension piece provided in connection with said mouthpiece and extending into the container, said first extension piece ending in a distal opening of reduced size relative to the mouthpiece whereby, in use, in the event that the container is knocked over from it upright position said distal opening will be substantially above the water level so that water is inhibited from spilling out of the container through the mouthpiece.  
   
   
       15 . A spill-proof smoking implement as defined in  claim 14 , wherein said extension piece is formed integral with the mouthpiece.  
   
   
       16 . A spill-proof smoking implement as defined in  claim 11 , further comprising a second hollow tapered extension piece provided in connection with said elongate pipe and extending into the container, said second extension piece ending in a distal opening of reduced size relative to said one end of the pipe whereby, in use, in the event that the container is knocked over from it upright position said distal opening will be substantially above the water level so that water is inhibited from spilling out of the container through the pipe.  
   
   
       17 . A spill-proof smoking implement as defined in  claim 16 , wherein said distal opening of the second extension piece extends below the water level in the container.  
   
   
       18 . A spill-proof smoking implement as defined in  claim 1 , further comprising a handle fixed to a side wall of the container that can be used to lift the smoking implement.  
   
   
       19 . A spill-proof smoking implement as defined in  claim 16 , wherein said handle has a lighter provided integral therewith that can be used to light the tobacco received in the receptacle.
