The feature or features that provide this preferred form of connection between tank B and lid C will be described and discussed below.

(26) Referring to FIGS. 1 to 9, the liquid retaining tank B preferably houses and/or stores water or other suitable filtering liquid at a sufficient level to filter the material being smoked through the stored or housed liquid prior to the individual inhaling the smoke or vapor. As seen in FIGS. 8 and 9, tank B includes a main body or main section 2 having an enlarged central opening 4 formed in upper horizontally extending surface 6 of main body 2. Tank B can be readily filled to the desired level by pouring liquid into tank B through enlarged opening 4. For example, central opening 4 may be readily aligned with a sink faucet to fill tank B to the desired level water or liquid level. It should be noted that an upper portion of tank B should include only a gas or gas vapor, i.e., tank B is not to be completely filled with water or other suitable liquid.

(27) Preferably, main section or body 2 is formed from a single piece of bent, transparent plastic, opposing ends of which are connected in a sealed manner using any suitable connecting technique (e.g., fusion bonding or any type of suitable welding including but not limited to ultrasonic welding, vibration welding or induction welding), material (e.g., any suitable adhesive or bonding substance) and/or mechanical fasteners. However, the main body 2 can be formed from any suitable material including but not limited to non-transparent plastics or metals. Further, the main body or section 2 can be formed from two or more pieces connected in a fluid tight manner with any suitable connection means or technique.

(28) Tank B further includes left and right sidewalls 8 and 10 each preferably formed from a single piece of transparent plastic connected to the left and right sides, respectively, of main body 2, in a fluid tight manner using any suitable connecting technique or means. However, sidewalls 8 and 10 can be formed from any suitable transparent or non-transparent material. Preferably, sidewalls 8 and 10 are identical in configuration and size.

(29) Segments 12 and 14 forming the lower front and rear portions, respectively, of main body 2 can be arcuate, rounded or beveled to facilitate cleaning of tank B, as seen in, for example, FIGS. 1, 2 and 9. Preferably, the radius of curvature of segments 12 and 14 is identical or substantially identical. Tank B further includes left and right peripheral, anti-skid, protection members 16 and 18 mounted on and about sidewalls 8 and 10, respectively. Members 16 and 18 can be formed from any suitable material including rubber or other elastomeric material. Preferably, members 16 and 18 are identical allowing either member to be mounted on and about either sidewall. Each of members 16 and 18 preferably includes vertically extending inner and outer annular lips 20 and 22, respectively and an annular groove/recess 24 extending between annular lips 20 and 22 as is seen in, for example FIG. 9. An outer peripheral/annular portion of a corresponding sidewall seats in the annular groove 24 of the corresponding anti-skid, protection member. Outer lip 22 preferably directly engages or is positioned adjacent an outer vertically extending surface of a corresponding sidewall and inner lip 20 preferably directly engages or is positioned adjacent an inner vertically extending surface of a corresponding sidewall. Preferably, inner lip 20 extends parallel or substantially parallel to outer lip 22. Inner lip 20 and outer lip 22 preferably extend inwardly from outer surface 26 of the corresponding anti-skid, protection member. Preferably, outer lip 22 extends inwardly from outer surface 26 a distance greater than the distance inner lip 20 extends inwardly from outer surface 26.

(30) Sidewalls 8 and 10 and members 16 and 18 can each be provided with four complimentary arcuate or rounded corner sections. Preferably, tank B is symmetrical or substantially symmetrical such that a vertical plane passing through a center of tank B and extending from segment 12 to segment 14 divides tank B into left and right symmetrical or substantially symmetrical portions and a vertically extending plane passing through a center of tank B and sidewalls 8 and 10 divides tank B into front and rear symmetrical or substantially symmetrical portions.

(31) Preferably, upper and horizontally extending surface 6 (see FIGS. 8 and 9) of main body 2 is offset downwardly from an uppermost surface of each of sidewalls 8 and 10 and an uppermost surface of each of members 16 and 18.

(32) Removable lid C includes an upper, exterior surface 30 extending between arcuate front surface 32 and arcuate rear surface 34 and left and right sidewalls 35 and 37, respectively as seen in, for example, FIGS. 1, 10 and 12. Preferably, surface 30 is a horizontally extending or substantially horizontally extending surface. Arcuate surfaces 32 and 34 can have the same radius of curvature. Further, the radius of curvature of segments 12 and 14 can be the same as the radius of curvature of surfaces 32 and 34.

(33) In a most preferred form, hookah assembly A is configured to resemble a military tank with members 16 and 18 resembling the continuous tracks of a military tank, raised section/segment 36 resembling a military tank's turret and connection conduit/port 38 resembling the gun/barrel of a military tank.

(34) An upper portion of interior chamber 40 formed by raised section 36 is in fluid communication with an internal cavity or bore 42 of conduit 38 which extends the length of conduit 38 as seen in, for example FIG. 16. A lower portion of interior chamber 40 is formed by inner section 44 extending downwardly from raised section 36. An inlet opening 46 is formed in the bottom of inner section 44 as is seen in, for example, FIG. 16. Conduit or port 38 preferably includes external threads 48 to detachably connect conduit 38 to raised section 36 at opening or internal bore 50 having complementary internal threads as seen in, for example, FIGS. 11, 11A and 16. This configuration allows an inhalation tube, hose or conduit to be detachably connected to conduit 38 so that an individual can inhale smoke or vapor in the liquid retaining tank B. The smoke or vapor travels upwardly from the tank B through chamber 40, bore 42 and the inner bore or cavity of the inhalation tube, hose or conduit to the mouth of the individual using the hookah assembly A.

(35) Referring to FIGS. 11, 11A and 20, an annular groove 60 is formed on an inner surface of lid C. The annular groove or recess 60 is configured to receive annular seal 62 so that at least a portion of annular seal 62 seats in annular groove 60. Annular seal 62 surrounds and engages downwardly and vertically extending inner annular wall portion 64. Annular wall portion 64 extends into the chamber formed by tank B as seen in, for example, FIGS. 5 and 7.

(36) The four corner sections 66a, 66b, 66c and 66d of annular wall portion 64 are each configured to receive and support an o-ring 68 or other sealing element and seal protection cover member 70. The corner sections 66a, 66b, 66c and 66d are configured identically or similarly and, therefore, only one corner section 66a will be described in detail.

(37) Referring to FIGS. 11 and 11A, corner section 66a includes a cylindrical portion 72 and a seal seating and support surface 74 surrounding cylindrical portion 72. Cylindrical portion 72 extends upwardly from seal seating surface 74. Seal seating surface 74 extends horizontally or substantially horizontally and includes an arcuate outer edge and an arcuate inner edge O-ring 68 sits on surface 74 and surrounds and engages cylindrical portion 72. An interior and arcuate wall portion 76 extends around and upwardly from the inner arcuate edge of surface 74. The corresponding inner portion 78 of o-ring 68 directly engages or is positioned adjacent wall portion 76 so that wall portion 76 will prevent inward movement of inner portion 78 of o-ring 68 or restrict the amount of inward movement of portion 78 of o-ring 68. Outer portion 80 of o-ring 68 extends outwardly from the outer surface 82 of wall portion 64.

(38) Cover member 70 sits on cylindrical portion 72 and is detachably connected thereto by a fastener 90. Cover member 70 includes an opening 92 for receiving fastener 90. Cylindrical portion 72 includes an internally threaded bore 94 having complementary threads to fastener 90 so that fastener 90 can detachably or removably connect cover member 70 and o-ring 68 to cylindrical portion 72. Outer portion 96 of cover member 70 is offset inwardly from portion 80 of o-ring 68 so that portion 80 of o-ring 68 extends outwardly from outer portion 96 of cover 70.

(39) The orientation of outer portion 80 of each of the four o-rings 68 so that it extends outwardly from both surface 82 and portion 96 allows outer portion 80 of o-rings 68 to engage the adjacent corner portion of inner surface 100 (see FIG. 2) of main body 2 to releasably lock a corresponding corner of lid C to a corresponding portion of tank B. The resilient nature and/or the configuration and sizing of each of the four o-rings 68 allows an individual to remove lid C from tank B by moving lid C (e.g., sliding lid C in a horizontal plane and in a direction parallel to sidewalls 8 and 10) relative to tank B to free one or more of the o-rings 68 (e.g., free two o-rings 68) from the corresponding portions of tank B to allow the lid C to be removed from tank B. For example, sliding lid C in a forward direction parallel to sidewalls 8 and 10 will free the two o-rings 68 disposed adjacent the two opposing rear corners (i.e., the corners closet to arcuate surface 34) of enlarged opening 4. This sliding movement may but does not necessarily compress the two o-rings 68 disposed adjacent the two opposing front corners of enlarged opening 4 (i.e., the corners closer to raised section 36 and arcuate surface 32).

(40) When all four o-rings 68 engage the corresponding adjacent corner portion of inner surface 100 (see FIG. 2), lid C and tank B may be raised as a unit by merely lifting any portion of lid C (e.g., by gripping only raised section 36 or only conduit 38) or any portion of tank B. When connected in this manner, annular seal 62 seats on upper surface 6 of main body 2. This sealing engagement prevents fluid from entering or exiting tank B through the peripheral or outer portion of enlarged opening 4.

(41) In the preferred embodiment, a plurality of arcuate exhaust slots 102 (e.g., four arcuate slots) surround bowl support E and extend through lid C as seen in, for example, FIGS. 1, 3, 10 and 12. Preferably, the four slots 102 are equidistantly spaced about bowl support E. However, the number, shape and spacing of openings 102 can be readily varied as desired. As explained in more detail below, an exhaust valve is operably associated with each of the openings 102 so that openings 102 are normally closed preventing a fluid from entering or exiting tank B through openings 102. The exhaust valves are configured to open when an individual blows air into the inhalation hose, conduit or tube during a purge process to allow residual vapor or other fluid to be exhausted or purged from tank B directly through lid C via openings 102.

(42) Referring to FIG. 11, bowl support E is illustrated in an inverted position. Bowl support E includes an inwardly tapered annular portion 112 which is configured to support a bowl of tobacco or other substance and extend upwardly through opening 113 in lid C. Annular portion 112 may be formed from a tapered tubular piece of metal surrounded by a tapered rubber seal which contacts and seals the area between the tapered tubular piece of metal and an adjacent portion of upper surface 30 lid C. Bowl support E further includes an outer, annular wall or lip portion 114 which is spaced outwardly from and surrounds portion 112. An annular groove or recess 111 is formed between outer, annular wall portion 114 and tapered annular portion 112 having a seating surface 116 as seen in, for example, FIG. 16. Four small bores 115 preferably extend through the seating or bottom surface 116 of bowl support E to receive fasteners 118 to detachably connect bowl support E to downwardly extending annular member 120 of lid C for forming a section or segment of exhaust valve assembly F as seen in, for example, FIGS. 11 and 16.

(43) Four through bores 122 are preferably provided with each bore 122 disposed between adjacent bores 115 and extending through the corresponding portion of bowl support E. Preferably, the upper end of each of bores 122 are larger than the lower ends of bores 122 so that a sealing ball 124 or other sealing element can be inserted into each of the bores 122 through the upper end. The lower end of each of bores 122 is smaller than the sealing ball 124 to retain the sealing ball 124 in the corresponding bore 122 of bowl support E.

(44) Annular member 120 of lid C includes four horizontally extending surfaces 129 each having a threaded opening 130 configured to receive a corresponding one of the four fasteners 118 to detachably connect bowl support E to annular member 120 as seen in, for example, FIGS. 11 and 11A. Annular member 120 includes four elongated arcuate slots, recesses or depressions 132 that are in fluid communication with a corresponding slot 102 as seen in, for example, FIGS. 11, 11A and 20. Each slot, recess or depression 132 includes an outwardly inclined inner surface 134.

(45) The down-stem and integral diffuser D will now be described in detail. Down-stem D preferably includes an upper end 150 having an annular recess or groove 152 which receives o-ring 154 as seen in, for example FIG. 11. O-ring 154 seats in annular groove 156 of bowl support E to detachably connect down stem D to bowl support E, i.e., o-ring 154 expands outwardly to seat in annular groove 156 of bowl support E. Down-stem D includes a lower end 160 which is preferably configured to extend into the liquid housed or retained by tank B.

(46) Lower end 160 is preferably a diffuser which diffuses the smoke or vapor to be inhaled through the water or other suitable liquid housed or stored in tank B. Preferably, lower end 160 includes three annular grooves or recesses 170 as seen in, for example FIG. 19. A single piece of metal or other suitable material forms external housing 171 and internal bore 173 of the down stem and integral diffuser with internal bore 173 extending vertically and completely through the down stem D. A plurality of horizontally extending openings 172 having a diameter greater than the width or height of grooves 170 extend through lower end 160 and a corresponding groove 170 to communicate with internal bore 173 as seen in, for example, FIG. 19. An o-ring 180 preferably seats in each of the annular grooves or recesses 170. The o-rings 180 act to divide or separate the horizontally extending openings 172 into upper and lower openings 181 and 183, respectively,

(47) having a smaller size than any one of the opening 172. This arrangement significantly reduces the size and number of openings that need to be formed in the diffuser section of the down stem D. This arrangement is advantageous as the smaller openings created by the o-rings 180 significantly reduce the noise caused by the operation of hookah assembly A. Further, o-rings 180 act to divert the smoke or vapor along different paths from the path of a purely horizontally extending opening.

(48) Referring to FIG. 19, down stem D includes a ball valve 200 which is designed or configured to move vertically in lower section 202 of internal bore 173 of down stem D. As seen in FIG. 19, lower section 202 has an internal diameter greater than upper section 203 of internal bore 173. In FIG. 19, ball valve 200 is depicted in a closed position or uppermost position which occurs during an exhaust or purge process or step. In a normal state of operation, ball valve 200 rests in the lowermost end of down stem D allowing vapor to pass downwardly through internal bore 173 and out through the upper and lower openings formed by the o-rings 180 and into the water or other liquid housed in the liquid retaining tank B. Down stem D includes an o-ring 204 which seats in an internal annular groove 206 formed in a bottom portion of section 160 and removably retains ball valve 200 of down stem D, i.e., upon removal of o-ring 204, ball valve 200 can be readily removed from down stem D.

(49) During normal operation, an inhalation tube, hose or conduit is connected to port 38, and tank B is filled with water or other suitable fluid so that lower section 160 of down stem D is disposed or submerged in water or other suitable fluid. The substance to be smoked is mounted on or about an upper portion of the bowl support E. The material to be smoked is then ignited. The vapor of the material being smoked is drawn downwardly through the bowl support E and out open end 220 and/or the upper and lower horizontally extending openings/bores of down stem D and is filtered by the water or other liquid in tank B. During this process, ball valves 124 of the purge or exhaust assembly F are seated in a closed position so that air surrounding the hookah assembly A cannot pass into tank B through slots 102. The vapor then passes upwardly through the liquid in tank B and opening 46 of chamber 44, raised section 36, port 38 and the inhalation tube, hose or conduit connected to port 36 into the mouth of an individual using hookah assembly A. During this smoking operation or process, ball valve 200 is in a lowermost or open position directly adjacent o-ring 204.

(50) When an individual seeks or wants to exhaust or purge residual vapor or smoke in tank B, the individual need merely blow into the inhalation tube, which in turn causes each of the four balls 124 of the purge or exhaust assembly F to move upwardly off of the seated or closed position to allow vapors in the tank B to be directly exhausted or purged through slots or openings 102 formed in upper surface 30 of lid C. Arcuate slots 132 allow balls 124 to travel a sufficient distance from the seated or closed position to allow the purging or exhausting of any residual vapor or smoke from tank B. This processes also causes ball valve 200 to move upwardly to seal down stem D so that no fluid can travel upwardly through down stem D which prevents any fluid (e.g., water) from contaminating the material to be smoked which is supported by bowl support E.

(51) While this invention has been described as having a preferred design, it is understood that the preferred design can be further modified or adapted following in general the principles of the invention and including but not limited to such departures from the present invention as come within the known or customary practice in the art to which the invention pertains. The claims are not limited to the preferred embodiment and have been written to preclude such a narrow construction using the principles of claim differentiation.
