Abstract

A traditional bong is provided having an upright barrel divided by a partition into a lower, dry chamber into which the pipe stem enters, and an upper aqueous chamber which is made spill-proof by virtue of a stand pipe extending up from the lower chamber through the baffle, this stand pipe being covered by an elongated cap which bobbles up and down in the liquid-filled upper chamber as the device is used and seals against an opening and an overlying baffle when the bong is inverted to prevent spillage. An additional novel effect is produced by the bobbling of the diverter cap which covers the stand pipe, which tends to mix the inhaled smoke with the water as it bobbles.

Claims

1. A bong comprising:

(a) an upright barrel;

(b) a partition extending across said barrel defining an aqueous chamber over said partition;

(c) a hollow stand pipe extending upwardly through said partition into said aqueous chamber such that liquid maintained in said aqueous chamber at a level below that of the top of said stand pipe will not drain through said stand pipe;

(d) a pipe bowl mounted on said barrel and means defining a smoke passageway between said bowl and the bottom of said stand pipe; and

an elongated stand pipe cap covering and extending down alongside said stand pipe and communicating with the top of said stand pipe to divert any smoke traveling up through said stand pipe back down into any liquid contained in said aqueous chamber, said pipe cap being restrained by said stand pipe to substantially vertical movement and otherwise is free to bobble in the liquid in said upper chamber and responds to the drawing of smoke upwardly in said stand pipe and downwardly in said stand pipe cap.

2. The structure according to claim 1 and including a baffle across said barrel above said aqueous chamber to define a mouthpiece thereover, and said baffle includes a breather hole aligned with the vertical path of said stand pipe cap such that said hole is blocked by said stand pipe cover to prevent spillage when said bong is diverted.

3. The structure according to claim 2 and including a breather hole extension tube downwardly directed from said baffle to further guard against spillage from bong inversion.

4. The structure according to claim 2 wherein said baffle is planar and extends outwardly from said barrel to define an extended non-circular perimeter to prevent rolling of said bong about its longitudinal axis when dropped.
