Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates generally to smoking accessories and, more specifically, to a Disposable Water Pipe Liner. [0003] 2. Description of Related Art [0004] Water pipes are a widely used apparatus for recreational smoking of tobacco and other materials. FIG. 1 depicts a conventional water pipe. [0005] Although available in limitless sizes and shapes, the typical pipe 10, as depicted here, has an upright chamber tube 12. The chamber tube 12 terminates at its upper end in a mouth 14. Here, soft plastic rim cover 16 has been attached to the mouth 14, in order to improve the comfort and functionality of the pipe 10. [0006] The chamber tube 12 is held in an upright and stable position by the base 10. As stem 20 extends from an aperture formed through the wall of the chamber tube 12. The stem 20 terminates in the bowl 22 for placing and lighting the smoking materials. A soft (typically rubber or the like) grommet 24 seals the stem 20 to the chamber tube 12 to prevent air or liquid from entering or exiting the stem aperture 32 formed in the wall of the chamber tube 12. In many pipes, a carburetor aperture 26 is formed in the wall of the chamber tube 12 as well, in a position above the stem aperture 32. If we now turn to FIG. 2, we can examine the functioning of this device. [0007] FIG. 2 is a cutaway side view of the pipe 10 of FIG. 1. The chamber tube 12 defines a chamber 28 bounded on its top end by the mouth 14, and further has an open bottom end. The inner surface 29 of the tubular wall of the chamber tube 12 is smooth (since it generally is made from a translucent plastic or glass material. The bottom end is covered by a removable, liquid-tight bottom cap 38. The bottom cap 38 is typically obscured from view by the base 18. The bottom cap 38 can be removed (such as for cleaning, etc.) after first pulling off the base 18. [0008] The stem 20 extends through the chamber tube 12 wall and into the bottom portion of the chamber 28. Before use, the operator adds enough water or other liquid such that the inside end of the stem 20 is submerged, i.e. just below the stem aperture height 34. [0009] As should be apparent, when the operator sucks on the mouth 14, it will cause airflow to be pulled down the stem 20 and through the liquid 30 in the bottom of the chamber 28. As the smoke is drawn through the liquid 30, it will be cooled as well as being "scrubbed" somewhat by the liquid. The grommet 24 prevents air from leaking into the chamber 28 when under suction, and further prevents liquid 30 from leaking out around the stem 20. For future reference, the stem 20 is cylindrical and has an outer diameter 36. The carburetor aperture 26 is an optional feature on water pipes 10 that is covered and uncovered by the operator as desired to improve the smoking experience. [0010] The problem with these water pipes 10 is that the liquid tends to become soiled, smelly and unsightly if not cleaned thoroughly fairly often. As the liquid becomes soiled, it in turn transfers the contaminants to the inside surface 29 of the chamber tube in the form of brown stains. Serious scrubbing of the disassembled water pipe 10 many times will not be sufficient to remove all remnants of the brown stains. [0011] What is needed, then, is a device and method that prevents the tar buildup on the walls and stem of a conventional water pipe without the need to modify its original design. SUMMARY OF THE INVENTION [0012] In light of the aforementioned problems associated with the prior devices and methods, it is an object of the present invention to provide a Disposable Water Pipe Liner. The liner should be insertible into the chamber tube of conventional water pipe such that it prevents tar buildup on the inside walls of the chamber tube. The chamber tube liner should also have a pre-formed aperture designed to be aligned with the stem aperture in the chamber tube. The liner may further have 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 should also include a stem tube liner for slipping over the inner end of the stem to also prevent its being coated with tar and other deposits. BRIEF DESCRIPTION OF THE DRAWINGS [0013] The objects and features of the present invention, which are believed to be novel, are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages, may best be understood by reference to the following description, taken in connection with the accompanying drawings, of which: [0014] FIG. 1 is a perspective view of a conventional water pipe; [0015] FIG. 2 is a cutaway side view of the pipe of FIG. 1; [0016] FIG. 3 is a front view of a preferred embodiment of the chamber tube liner of the present invention; [0017] FIGS. 4A and 4B are perspective and cutaway side views of a preferred embodiment of a stem tube sheath of the present invention; [0018] FIG. 5 is a cutaway side view of the pipe of FIGS. 1 and 2 having the liner and sheaths of FIGS. 4A/4B and 5 installed therein; and [0019] FIG. 6 depicts the method for installing the devices of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0020] The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide a Disposable Water Pipe Liner.
