Abstract: A smoking pipe having a cleaning valve includes a pipe body with an internal bore. A combustion chamber is communicably connected with the bore. A cleaning valve is mounted adjustably within the bore. The valve includes a longitudinal channel and the valve is alternatable between a first position wherein the channel is communicably interconnects an orifice in the mouthpiece of the pipe and the combustion chamber and a second position wherein the channel is fully exposed so that it may be quickly and completely cleaned.

Abstract: An elongated tobacco smoking pipe having an outer band (12) that may slide along a body (10) and may be positioned to cover a transverse-smoking cavity (22). The outer band may have either a dimple (26) or a coating (28) to aid with friction. A bore (18) communicates with either an end-smoking cavity (20) or the transverse-smoking cavity or both to carry the smoke mixture to a draw end (14). An end cap (24) may be placed over the end-smoking cavity to secure the embers or the tobacco. Also an end cap (24a) with an end-cap hole (30) may be used to assist in controlling the smoke to air mixture. Either smoking cavity may have and inner liner (32) to protect the body from hot embers. The body may have two pieces (10a & 10b), allowing the smoker to cover the end-smoking cavity.

Abstract: A device for minimizing cigarette sidestream smoke and reducing the free-burn rate of a burning cigarette, the device comprises: I) a non-combustible tubular element (12) encasing an effective length of a tobacco charge (22) of a cigarette (14) located in a tubular element; and II) the tubular element having a means for both minimizing sidestream smoke emission from a burning tobacco charge and reducing free-burn rate of such burning tobacco charge to increase the number of puffs from the burning tobacco charge.

Abstract: A closed cigarette filter for preventing tobacco from coming into direct contact with the mouth of the user and filtering undesirable products in the smoke, which includes strip of filter material having one edge cut to define multiple, adjacent panels or fingers, which strip is capable of being shaped in a tubular configuration and applied to the end of a cigarette, with the upward-standing panels located above the open end of the filter and the panels subsequently folded inwardly, either in at random or in a repeating pattern, to close the open end of the filter and provide a filter medium. In a preferred embodiment of the invention the filter includes a vent which facilitates escape of smoke from the interior of the filter and prevents further accumulation of products of combustion on the panels when the cigarette is burning, but is not being smoked.

Abstract: A tubular, open ended elongated liquid impervious sheath bears internally, a removable tubular absorbent material liner. A buckled strap borne by the sheath adjacent its mouth permits the sheath to be frictionally clamped to the pipe stem adjacent the bowl ensuring retention of the stem within the lining which absorbs any liquid. The strap bears a pouch holding a cylindrical plug employed in closing off the sheath absent a pipe, and a replacement liner.
