Description

BACKGROUND

A hookah is a device used to smoke tobacco. The device has its origins in the Middle East and Near East regions. A typical hookah 10 as shown in FIG. 1, includes a water reservoir 12. A plug, cap or gasket 14 (either of which is referred to herein as a “cap” for illustrative purposes). The cap caps the reservoir. A stem 16 penetrates the cap such that a first end 18 of the stem is external of the reservoir whereas a second end 20 of the stem opposite the first end is within the reservoir. At least one hose 22 with optionally a mouthpiece (now shown) also penetrates the cap. To use the hookah, the reservoir is partially filled with water 25 leaving a head space 26 within the reservoir free of water while submerging the second end 20 of the stem 18 within the water. Each hose 22 extends within the head space 26 of the reservoir above the water. A tobacco bowl 28 is connected to the first end 18 of the stem. Specifically, the tobacco bowl 28 includes an opening 30 extending to its lower end for receiving the first end 18 of the stem. The tobacco bowl defines a conduit 32 extending from the opening 30 to interior of the bowl. Tobacco 31 to be smoked is placed within a tobacco support 34 defined within the bowl external of the conduit. A perforated coal plate 36 is mounted over the bowl.

Hookah tobacco, if often referred to as “massell.” Massell is a mixture of tobacco, molasses, and often a flavor or fruit extract, The molasses and fruit extract add a substantial amount of moisture to the massell that is missing in conventional tobacco. This added moisture makes massell more sensitive to the elements relative to conventional tobacco. To smoke the hookah, the massell or tobacco is placed within the tobacco support 34 of the bowl. The coal plate 36 is then mounted on top of the bowl covering the massell. Typically, there is a space between the upper surface of the massell and the coal plate as it is often desirable that the coal does not contact the massell. Lit coals 37 are placed on top of the coal plate. The heat from the coals ignites the massell. Smoke generated by the ignited massell travels through the conduit and the first end of the stem and exits in the water through the second end of the stem. The water cooled the smoke exits the reservoir through each hose 22 and corresponding mouth piece as the user inhales through the mouth piece.

With existing hookahs, as the coals burn down they provide less heat and thus, lower the quality of the smoke. As a result, the coals need to be replaced often.

DETAILED DESCRIPTION

In an example embodiment a hookah bowl 110 is provided that can be used with any hookah (FIG. 2). The hookah bowl in an exemplary embodiment has a lower member 112 and an upper member 114. The lower member has a section for interfacing with a hookah stem (16, FIG. 1). In the shown exemplary embodiment, the section for interfacing with the hookah stem is an opening 116 for receiving the stem, as for example shown in FIG. 3. In another example embodiment, the section can be an annular member extending from the lower portion of the lower member that is received within the stem or that receives the stem 16 of the hookah. A conduit 118 is formed inside the lower member defining a receptacle 120 around the conduit and surrounded by a peripheral wall 121 for receiving the tobacco (e.g., massell), as for example shown in FIG. 6. The conduit extends from the opening 116. The upper member may optionally include a cover 122 having a vent opening 124 for covering a top opening 125 of the upper member. The cover is removable providing access to a coal plate 126. The coal plate 126 is supported on one or more inner peripheral projections 128 extending radially within the interior of the upper member 114. In an example embodiment, a single peripheral projection 128 extends along a majority or the entire periphery of the interion of the upper member, as for example shown in FIG. 5. The peripheral projection supports the coal plate 122, as for example shown in FIGS. 2 and 5. The coal plate is plate preferably made of metal and perforated for supporting the coals used to ignite the massell. In an example embodiment, the upper member is couplable with the lower member such that a vertical distance 144 of the coal plate from a base 130 of the receptacle 120 may be varied.

In an example embodiment, the lower member 112 includes an annular lip 132 defining a surface 133 extending along a generally sinusoidal path defining a plurality of peaks 134 and valleys 136, as for example shown in FIGS. 2 and 6. The upper member 114 also includes an annular lip 138 complementary to the lower member annular lip also defining a surface 139 extending along a sinusoidal path forming peaks 140 and valleys 142 such that the peaks of the lower member lip may be received in the valleys of the upper member lip and the peaks in the upper member lip may be received in the valleys of the lower member lip, as for example shown in FIG. 2. The upper member is mated over the lower member such that the upper member annular lip 138 rests on the lower member annular lip 132. Rotating the upper member relative to the lower member causes the lip of the upper member to ride on the lip of the lower member along the sinusoidal path of the lower lip. In this regard, as the peaks of the upper member annular lip slide up on the peaks of the annular lip of the lower member, the upper member rises relative to the lower member as for example shown in FIG. 7 such that the distance 144 between the base 130 of the tobacco receptacle 120 and the coal plate 126, as for example the upper surface 146 of the coal plate increases. Similarly, as the as the peaks of the upper member annular lip slide down into the valleys of the annular lip of the lower member, the upper member lowers relative to the lower member, as for example shown in FIG. 2. In this regard, by rotating the upper member relative to the lower member, the vertical distance of the coal plate and the tobacco receptacle base can be varied. In use, a smoker, may rotate the upper member relative to the lower member to reduce the distance between the coal plate and the receptacle and thus, the distance between the coals and the tobacco as the coals burn and wears out. In this regard as the heat generated by the coals decreases the coals are brought closer to the tobacco, such that the heat to which the tobacco is exposed is not reduced as much as if the distance between the coals and the tobacco was kept the same. During a smoking session, a user may rotate the upper member relative to the lower member at multiple intervals each time decreasing the distance between the coal plate and thus, the coals and the tobacco so as to continuously keeping the heat experienced by the tobacco relative constant and the coals burn out. Keeping the heat to which the tobacco is exposed to constant provides for a better smoking experience.

The amount of variance in the distance between the base 130 of the receptacle 120 and the coal plate 126 is a function of the depth of the valleys and/or the height of the peaks in each member.

In an example embodiment, the upper member is rested on the lower member and is removable from the lower member by lifting. When a cap 122 is provided it caps the second member above the coal plate, such that the cap will extend over the coals.

In other example embodiments instead of a sinusoidal path, the lips may follow a saw tooth path. In another example embodiment, the upper member is threaded to the lower member such that as the upper member is unthreaded from the lower member the distance of the coal plate from the receptacle 120 is increased. In any of the aforementioned exemplary embodiments, the upper member can rise relative to the lower member by at least 8 mm. In another exemplary embodiment, the upper member can rise relative to the lower member by at least 10 mm. In this regard, when the coals are freshly lit, the upper member is adjusted (e.g. rotated relative to the lower member) so as to increase the distance of the coal plate relative to the receptacle, as for example to the maximum distance 144, as for example shown in FIGS. 7 and 8 (e.g. an extended position). Once the coals wear by burning down, the coals can be brought closer to the tobacco as for example by further rotating the upper member relative to the lower member to reduce the distance between the receptacle and the coal plate up to the minimum distance 144 shown in FIG. 2 (e.g. a retracted position).

In a further example embodiment, the lower member 112 may be formed with an inner reservoir 150, surrounding the conduit 118, as for example shown in FIG. 9. The opening forms an inlet allowing a user to fill the reservoir 150 with a coolant, such as water, or other fluids that can serve as coolants. The coolant serves to further cool the burning of the tobacco and provide for a smoother smoke. The coolant may be removed from the reservoir through the inlet 152. In other example embodiments and inlet and separate outlet are provided. In a further example embodiment, instead of inlet/outlet 152 an inlet 154 which may also serve as the outlet is formed through a bottom of the lower member 112. A cap 158 is provided to cap the inlet 154. In another example embodiment, instead of an inlet and or outlet, the lower member 112 may be formed as at two piece member comprising an upper portions including the receptacle 120 that mates (as for example via threading) with a lower portion that defines the reservoir 150.

While in the shown example embodiment, the tobacco bowl has a generally spherical outer shape, in other example embodiments, the tobacco bowl may have other outer shapes. Moreover the annular lips 132, 138 or the sinusoidal surfaces 133, 139 may are not formed extending to the outer surfaces of the upper and lower members 112, 114 as shown but may be formed in internal members that interact with each other for changing the distance between the coal plate and the base of the tobacco receptacle.

In an example embodiment, the upper member may include depressions or openings 155 for receiving tool, as for example, a pin or rod for lifting the upper member from the lower member, especially when the upper member is heated.

In an exemplary embodiment, the tobacco bowl is made from concreter or ceramic material that allows the outer surface of the tobacco bowl to remain cool to the touch allowing the user to adjust the location of the upper member relative to the lower member. In other example embodiments, the tobacco bowl may be made from other materials, such as silicone, that allow the outer surfaces of the tobacco bowl to be cool to the touch.
