Disposable water pipe liner

Abstract

A Disposable Water Pipe Liner is disclosed. Also disclosed is a liner that is insertible into the chamber tube of conventional water pipe whereby it prevents tar buildup on the inside walls of the chamber tube. The chamber tube liner also has a pre-formed aperture designed to be aligned with the stem aperture in the chamber tube. The liner further has a plurality of guidelines inscribed upon it to aide users in trimming its length such that it is fitted to that user's water pipe. The liner also includes a stem tube liner for slipping over the inner end of the stem to also prevent its being coated with tar and other deposits.

1 . A liner for water pipes, comprising: 
 a flat sheet of flexible material defining a top edge, a bottom edge and right and left edges; and    a stem-oriented aperture formed in said sheet.    
     
     
         2 . The liner of  claim 1 , further comprising a plurality of radial slits emanating from said stem-oriented aperture, said radial slits formed though said sheet.  
     
     
         3 . The liner of  claim 2 , wherein said longitudinal slit is generally perpendicular to said bottom edge.  
     
     
         4 . The liner of  claim 3 , further comprising a plurality of guidelines inscribed on said sheet in generally parallel spaced relation.  
     
     
         5 . The liner of  claim 4 , wherein said guidelines are generally parallel to said bottom edge.  
     
     
         6 . The liner of  claim 5 , wherein said bottom edge and said top edge are parallel and said left and right edges are parallel, said right and left edges being perpendicular to said top and bottom edges.  
     
     
         7 . The liner of  claim 6 , wherein said flat sheet further comprises a longitudinal slit formed therethrough and extending between said stem-oriented aperture and said bottom edge.  
     
     
         8 . A liner and sheath combination for water-fillable smokers' pipes, said water pipes comprising a chamber tube having a height and a stem tube inserted into said chamber tube through a stem tube aperture, the combination comprising: 
 a liner comprising: 
 a flat sheet of flexible material defining a top edge, a bottom edge and right and left edges;  
 a stem-oriented aperture formed in said sheet; and  
   a sheath defining a generally cylindrical shape having an inner sheath diameter adequate to receive said stem tube therein.    
     
     
         9 . The combination of  claim 8 , wherein said liner further comprises a plurality of radial slits emanating from said stem-oriented aperture, said radial slits formed though said sheet.  
     
     
         10 . The combination of  claim 9 , wherein said liner further comprises a plurality of guidelines inscribed on said sheet in generally parallel spaced relation.  
     
     
         11 . The combination of  claim 10 , wherein said liner guidelines are generally parallel to said bottom edge.  
     
     
         12 . The combination of  claim 11 , wherein said liner bottom edge and said top edge are parallel and said left and right edges are parallel, said right and left edges being perpendicular to said top and bottom edges.  
     
     
         13 . The combination of  claim 12 , wherein said liner further comprises a longitudinal slit extending between said stem-oriented aperture and said bottom edge.  
     
     
         14 . The combination of  claim 13 , wherein said longitudinal slit is generally perpendicular to said bottom edge.  
     
     
         15 . A method for installing a protective liner and sheath into a water-fillable smokers' pipe having a chamber tube defined by a generally cylindrical wall and having a stem penetrating said wall, the method comprising the steps of: 
 disassembling said water pipe;    rolling a flat sheet of flexible material into a tube, said sheet defining a top edge, a bottom edge and right and left edges, a stem-oriented aperture formed in said sheet, and a longitudinal slit formed though said sheet between said stem-oriented aperture and said bottom edge;    inserting said rolled up sheet into said chamber tube; and    releasing said chamber tube.    
     
     
         16 . The method of  claim 15 , further comprising a sheath insertion step following said sheet inserting step, said sheath insertion step comprising slipping a stem tube sheath over said stem tube.  
     
     
         17 . The method of  claim 16 , wherein said liner of said rolling, inserting and releasing steps further comprises a plurality of radial slits emanating from said stem-oriented aperture, said radial slits formed though said sheet.  
     
     
         18 . The method of  claim 17 , wherein said liner of said rolling, inserting and releasing steps further comprises a plurality of guidelines inscribed on said sheet in generally parallel spaced relation.  
     
     
         19 . The method of  claim 18 , wherein said longitudinal slit of said liner of said rolling, inserting and releasing steps is generally perpendicular to said bottom edge.
