In such a position,the reservoir 12, groove 14 and end of said length10 of the bore 4 are covered by a continuous area of thewall defining the socket 20, whereby there is no passage5 from said volumes back into the cavity 18 of the bowlcavity 18. A tapering socket 20 extends transverselyof the lower regions of the bowl portion 16below the cavity 18, the dimensions of said socket 20corresponding with those ofthe end extent 8 ofthe stemportion 16. Thus there is no possibility of any liquid inthe stem portion 2 contaminating the bowl portion 16.One or more peripheral grooves such as that shownat 28 are formed around the stem portion 2 adjacent theportion 2 such that said extent 8 is a friction push-fit in 10bowl portion 16 to improve the grip of a user on saidthe socket 20 and such that the stem portion 2 and bowlportion 16 can be rotated relative to one another aboutthe central longitudinal axis of the stem portion 2.A passageway 22 is formed in the bowl portion 16 tostem portion 2 as the bowl portion 16 is being rotatedprior to tapping out unwanted ash.The provision of the angled extent 10 in the bore 4serves a dual purpose in that it enables direct communicationof the bore 4 with the passageway 22 and alsoextend between the lower regions of the cavity 18 and 15the socket 20, said passageway terminating in the surfaceof the socket 20 at a point aligned with the end ofthe length 10 of the bore 4 in the stem portion 2,whereby said passageway 22 is in direct communicationwith, and forms an extension of, said bore 4 when the 20stem portion is in its normal position relative to thebowl portion as shown in FIG. 1.An annular groove 24 is formed in the bowl portion16 communicating into the lower regions of the cavityraises the point of overflow from the groove 14 into thereservoir 12, effectively increasing the capacity of saidreservoir. Further, the nature of the bore 4 enablesready passage therethrough of a pipe cleaner.If desired, the narrow groove 14 could be increasedin size somewhat into the form ofa a secondary reservoir,but of smaller size than that of the reservoir 12.
