Patent Description:
The subject matter described herein relates generally to a system, device, and method of preparing tobacco, or other organic material, for smoking using a water pipe. Existing and traditional water pipes generally include a plate for supporting charcoal, a head for containing tobacco, a body including an internal pipe, a base for containing water, and a hose. Typically, a user will first fill the base with water and then place the internal pipe into the water such that the body creates an airtight seal with the base. The head is then filled with tobacco, or other organic material, and placed over the internal pipe such that an airtight seal is created between the internal pipe and the head. Next the user places the plate over the head, places one or more lit charcoals on the plate and these charcoals serve to heat the tobacco, or other organic material, underneath the plate. The hose is typically attached to the body such that it has an airtight connection with air above the water in the base. The user can inhale through the hose, which draws smoke from the heated tobacco, or other organic material, in the head through the internal pipe, through the water contained in the base, through the hose and into the user's lungs.

<CIT> shows an example of a common water pipe and is incorporated by reference herein in its entirety. In <CIT> discloses a system for facilitating smoking of tobacco from a hookah having a bowl with an interior space for holding organic matter to be smoked by a user, a heating platform for resting on the bowl with a central surface including a depression with at least one surrounding wall such that a heating source will not slide off the central surface; in particular, this document shows and describes a system comprising the features mentioned in the preamble of the present claim <NUM>. In <CIT> discloses a single use pre-packed disposable hookah (sheesha) container head contains tobacco or tobacco and charcoal. The container may be rigid, semi-rigid or flexible, malleable or re-shapeable material with or without perforations. <CIT> discloses a system for facilitating smoking of tobacco from a hookah including a bowl with an interior space defined by an inner surface and one or more walls separating the inner space into a plurality of compartments for holding organic matter to be smoked by a user and a supporting a cap for holding a heat source.

While standard water pipes are known, the embodiments provided herein teach features and advantages heretofore untaught by the prior art, as will be clear to one of ordinary skill in the art.

The invention provides a system as defined in claim <NUM> for facilitating smoking a water pipe.

Provided herein are embodiments of systems for smoking tobacco, or other organic material, through a water pipe and water pipes comprising such systems. The water pipe is different in form and function from traditional water pipes and provides a new experience for users, unknown in the industry.

A hookah is a water pipe known for centuries that has maintained a single, basic form. Traditional hookah pipes commonly include single chamber for holding water or other liquid that resembles a vase, and a pipe, hose, and bowl for holding tobacco. When being used for smoking or storing in an upright orientation, traditional hookahs have a center of gravity that is often located some distance above the surface on which the hookah pipe is resting. This high center of gravity can be prone to tipping over, especially when multiple users are sharing a smoking experience, where they may be passing hoses between each other. In a departure from the traditional orientation, the water pipe device disclosed herein has a low center of gravity and is therefore much more stable and less prone to falling over. As such, the water pipe devices disclosed herein provide improved safety and cleanliness compared with traditional hookah pipes since there is a reduced likelihood that the water pipe will tip over, causing coals or other heating implements to burn property or individuals and there is a reduced likelihood that the liquid holding chamber will spill or break. Similar advantages are also disclosed with respect to new bowl mechanics that are disclosed herein, providing mechanisms for securely coupling tobacco, or other organic material, holding bowls to the new water pipe devices and thus improving safety and cleanliness over prior art hookah pipes.

Operation of a traditional hookah pipe includes heating tobacco, or other organic material, in a bowl, drawing smoke from the heated tobacco, or other organic material, through a pipe and into water in the liquid chamber and then into the user's lungs. This has traditionally offered a smoke, which can be cooler in temperature, smoother in experience, and cleaner than other smoking implements, such as cigarettes and cigars. The water pipes disclosed herein further improve on the traditional hookah pipe in that they can provide users a cooler temperature and smoother smoking experience than a traditional hookah pipe. Disclosed herein are water pipes that provide various mechanisms for achieving these improvements including an increased surface area for smoke to cool, improved, and as yet unknown, purge valves and other inventive advancements not heretofore known.

To elaborate, various new types of water pipes are disclosed herein. In particular, some of these water pipes include a bowl that is pushed into a neck or hole from one direction. Some of these water pipes utilize two part downstem systems that separate to allow for upper and lower sections to create a seal over a hole in a glass dome from two directions. For these embodiments, once the seal is formed by screwing, or otherwise coupling the upper and lower sections to one another, there is a nipple at the top of the downstem to which a silicone bowl can be coupled. This allows for an airtight system, which is ideal for smoking and is an improvement on traditional hookah pipes that rely on a male or female bowl that connects with a stem and allow for smoke to travel from the bowl through the stem and into the base where water is held.

The devices and components described herein also promote improved social and personal smoking experiences by incorporating lighting, music, new smoking aesthetics, and improved storage abilities over traditional hookah pipes.

Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the present invention.

Illustrated in the accompanying drawing(s) is at least one of the best mode embodiments of the present disclosure; a system in accordance with the present claim <NUM> is derivable for example from <FIG>. In such drawing(s):.

The following description of the preferred embodiments of the invention is not intended to limit the invention to these preferred embodiments, but rather to enable any person skilled in the art to make and use this invention. Further, the figures herein are not meant to be limiting based on any scale or size relation illustrated but rather are meant to be example embodiments illustrative of concepts. Although any methods, materials, and devices similar or equivalent to those described herein can be used in the practice or testing of embodiments, the preferred methods, materials, and devices are now described.

<FIG> shows an example embodiment of a prior art water pipe, known also as a hookah pipe <NUM>. As shown in <FIG>, a head <NUM>, body <NUM>, base <NUM> and hose <NUM> are the primary components in a typical water pipe device. As shown in FIG. 1A, in general, the base <NUM> comprises a concave vessel having an open top portion for containing water or other liquid therein. The body <NUM> has a stem that extends into the base such that a distal end of the stem is partially submerged within the liquid contained in the base <NUM>. The body <NUM> couples with an open top portion of the base <NUM> so as to form a substantially airtight seal therewith. Accordingly, a first base grommet may be provided to couple the body <NUM> and the base <NUM> so as to form the substantially airtight seal. In this manner, a chamber is formed by the base <NUM> and body <NUM>. A hose <NUM> couples with the body <NUM> such that a proximal portion of the hose <NUM> has an airtight seal with the body <NUM>. Accordingly, a hose grommet may be provided to couple the hose <NUM> and the body <NUM> so as to form the substantially airtight seal. In some embodiments, a hose valve (not shown) may be intermediate the hose <NUM> and the body. The head <NUM> couples to a proximal end of the body <NUM> such that a substantially airtight seal is formed therebetween. Accordingly, a third grommet may be provided to couple the head <NUM> and the body <NUM> so as to form the substantially airtight seal. In operation, organic matter to be smoked may be contained within a bowl of the head <NUM>, and the head <NUM> can be covered with a cover, such as punctured foil, or a ventilated cover described in <CIT>, the entire contents and disclosure of which is herein incorporated by reference. Coals or other combustible heating material can be placed on or in the cover to heat the organic matter to be smoked, such as tobacco.

Critically, the head <NUM>, body <NUM> and hose <NUM> each comprise a hollow tube such that when the base <NUM>, head <NUM>, body <NUM> and hose <NUM> are coupled, an airflow path is formed. A user of prior art hookah <NUM> will generally inhale at the distal end of hose <NUM> and thus draw heated air into head <NUM>, causing the organic material therein to burn, releasing smoke that is subsequently drawn through the through body <NUM> and through the liquid in base <NUM>. The smoke then rises through the liquid into the area above the liquid in base <NUM>, becoming filtered in the process, and out through the hose <NUM> to be smoked by the user.

Other water pipe components, such as purge valves, ashtrays, base flavorings, etc. are generally known in the art and, while not specifically described herein, are intended to be useable in combination with the presently described embodiments without departing from the scope of the invention.

<FIG> shows an example embodiment diagram 500e of a bowl <NUM> with separate chambers <NUM> and downstem <NUM> with aerator subassembly <NUM>. As shown in the example embodiment, separate chambers <NUM> or compartments for tobacco or other organic material can provide containment in different locations within bowl <NUM>. Chambers <NUM> are defined by walls <NUM> that can slope and meet at a lower end and a circumferential wall <NUM>. In the example embodiment, the separate chambers <NUM> are shown in a spiral configuration with a central pipe <NUM> at the center. The separate compartments <NUM> can provide flavor mixing advantages not present in the art. For instance, one compartment <NUM> can be used for a first flavor of tobacco, or other organic material, while a second compartment <NUM> can be used for a second flavor, until each compartment <NUM> is filled. Unique and easily reproducible combinations can be created by a user based on this design. This is in stark contrast to the traditional single compartment design.

As shown for example in <FIG>, a bowl <NUM> preferably generally comprises a substantially hemispherical bowl head <NUM> extending vertically and radially from a substantially cylindrical bowl stalk <NUM>. As shown, bowl stalk <NUM> may be flared outward at its bottom end to facilitate easier manipulation. The bowl <NUM> preferably further comprises interior <NUM> and exterior <NUM> surfaces separated by a rim portion <NUM>. In some embodiments, located central to the bowl head <NUM>, and forming a portion of the inner surface of the bowl <NUM>, may be a hollow tube <NUM> extending the length of the bowl <NUM> from the bowl head <NUM> through the bowl stalk <NUM>.

Bowl head <NUM> preferably further comprises a plurality of compartments <NUM> therein for containing the organic matter or other material to be smoked. Accordingly, internal walls <NUM> may separate adjacent compartments <NUM>. A plurality of internal walls <NUM> may extend inward from the interior surface of the bowl head to hollow tube <NUM>, forming the plurality of compartments <NUM>. Accordingly, each internal wall <NUM> may partially or wholly separate adjacent compartments <NUM>. Compartments <NUM> may have varied dimensions and may be uniform or sized differently in different embodiments. In the example embodiment, each compartment is of equal depth and similar dimensions and shape. Each compartment may have a "U" shaped cross sectional profile when viewed from a side. Alternatively, each compartment may have a "V" shape, open-top square shape, open-top rectangular shape or other shapes.

As shown in FIG. 5W, in some embodiments the compartments <NUM> are slightly recessed from an upper elevation of the rim <NUM>, forming a space <NUM> between a cover and the organic matter to be smoked so as to promote airflow from the organic matter to the hollow tube <NUM>.

In at least one embodiment, bowl <NUM> is made of silicone material. Silicone may have advantages such as improved insulation around the head <NUM> and improved heat distribution inside the head 505and may also provide improved uniformity of heat distribution. Improved insulation around head 505may provide an improved user experience since users are less likely to burn themselves when handling bowl <NUM> when it is hot. Improved heat distribution inside head <NUM> may provide an improved user experience since it promotes even heating characteristics for organic matter in compartments <NUM>. As such, organic matter may be evenly heated and less likely to have some portions burn while others remain unheated. In other embodiments clay, marble, glass, or other appropriate materials may be used.

In accordance with the bowl of <FIG>, a user can insert a metered amount of tobacco, shisha or other organic material into one or more of compartments <NUM> before or after coupling bowl <NUM> with a stem of a water pipe in order to prepare the bowl <NUM> for smoking.

In another example embodiment, compartments can be arranged concentrically around the central pipe. In the example embodiment, the separate compartments are slightly recessed from the top of the head. That is, the barriers between separate compartments do not extend to the upper end of the head. In the example embodiment, this can create a small gap between the lower surface of a plate for coal support and the upper surface of the tobacco, or other organic material, to be heated where the tobacco, or other organic material, is inserted in the compartments to the same upper height as the upper end of the ridge barriers. This arrangement can serve to protect the tobacco, or other organic material, from becoming too hot and burning which can create an unpleasant and harsh smoke for the user. The small gap can also serve as a small compartment for pleasant smoke created by the heated tobacco, or other organic material, to reside before being drawn downward through the central pipe. In some embodiments, they can extend to the upper end of the head.

<FIG> shows an example embodiment diagram 500f of a bowl <NUM> and downstem <NUM>.

<FIG> shows an example embodiment cross-sectional diagram <NUM> of a bowl <NUM>, plate <NUM> and coupled cap <NUM>. Bowl <NUM> can be an example embodiment of bowl <NUM> of <FIG>.

<FIG> shows an example embodiment cross-sectional diagram <NUM> of a bowl <NUM>, plate <NUM> and coupled cap <NUM>.

<FIG> show a perspective view of a head with separate compartments for tobacco, or other organic material, containment. In typical prior art heads, a single compartment is provided for housing tobacco. In the example embodiment, a plurality of separate compartments are shown for housing tobacco, or other organic material. Each compartment shown can extend radially outward in a spiral from a central pipe that extends through the head for a portion or from top to nearly the bottom. In operation, the central pipe can allow a user to draw air from above the central pipe through the central pipe. The separate compartments shown each have identical dimensions although in other embodiments differing dimensions can be used. For example, a single compartment can be half of the head while the other half of the head can be split in two for a total of three compartments. Similarly, in some embodiments compartments can be arranged differently.

<FIG> show a perspective cross-sectional view <NUM> and side cross-sectional view <NUM> of an example embodiment of a dual component bowl <NUM> in accordance with the present invention. In various embodiments, an outer bowl <NUM> is provided with an inner bowl 502i which can be a different material and can be fixed or removable with respect to outer bowl <NUM>.

Then, in operation during a purge cycle, open purge valves 1326b can allow airflow to escape in a gap between bowls <NUM> and one or more portions of an outer vessel <NUM>, here an outwardly flared upper cap area.

<FIG> shows an example embodiment of a side cross-sectional diagram view of domed water pipe <NUM> with supporting tray <NUM> including a second purge airflow cycle 1300e. As shown in the example embodiment, purge airflow cycle 1300c, a user can push air through a hose attachment <NUM>. This causes air to travel through manifold <NUM> and into smoke chamber <NUM>. Once in smoke chamber, airflow continues through one or more purge valves <NUM> in tray <NUM> and coupled directly with manifold <NUM> before exiting the domed water pipe <NUM>. The operation of purge airflow cycle 1300c allows users to purge smoke chamber <NUM> of overly heated or stale smoke that may remain within domed water pipe <NUM>.

<FIG> show example embodiments of platforms where like numbered elements correspond between the figures in their generally functionality. For example, a platform 1520a of <FIG> corresponds generally with a platform 1520c of <FIG>.

<FIG> show an example embodiment of a grinder platform setup. <FIG> show an example embodiment of a spiral platform setup. <FIG> show an example embodiment of a rose platform setup. <FIG> show an example embodiment of a rose platform setup. <FIG> show an example embodiment of another rose platform setup. <FIG> show an example embodiment of a rose-spiral platform setup. <FIG> show an example embodiment of a wall platform setup.

<FIG> shows an example embodiment of a platform <NUM> from a top view 1500a and side perspective view 1500b. As shown in <FIG>, platform <NUM> preferably comprises a recessed tray <NUM> for containing a heating source. In the example embodiment, a raised surface <NUM> can provide a slight elevation over a normal tray (not shown) or recessed tray <NUM> for charcoal or other heating elements to promote airflow below them. In <FIG>, <FIG> and <FIG> these are chevron shaped and as shown are in concentric rings whereby those in the inner ring are smaller and offset from those in the outer ring. In <FIG> and <FIG> these are rounded rectangular shaped about a central focal point and as shown are in concentric rings whereby those in the inner ring are smaller and offset from those in the outer ring. As shown in bottom view diagram 1500r of <FIG>, spiral and other ridge features can be included on a bottom surface of platform <NUM> to provide airflow management in various embodiments.

The platform <NUM> also preferably comprises a plurality of perimeter bowl vents <NUM> for permitting airflow between a heating chamber and a bowl while in operation. As shown, eight perimeter bowl vents <NUM> may be used although other numbers of perimeter bowl vents <NUM> are also contemplated. The platform <NUM> also preferably comprises a plurality of perimeter vertical protrusions <NUM> that mate with corresponding protrusions <NUM> of a cap to form adjustable side vents <NUM> for controlling the airflow between the exterior atmosphere and the heating chamber. In various embodiments, this mating may occur using screws and threading. As shown in the example embodiment, platform <NUM> can have a radius of about <NUM> millimeters.

As a cap <NUM> is rotated relative to the platform <NUM>, for instance by rotating cap <NUM> using a rim <NUM>, respective protrusions <NUM> and spaces therebetween (i.e. the formed circumferential vents <NUM>) may transition between fully open, partially open and fully closed with respect to adjustable side vents <NUM>. In this manner, airflow to the heating chamber may be controlled. In some embodiments, the cap <NUM> may further comprise additional upper vents <NUM>, which may or may not be adjustable in different embodiments. Perimeter bowl vents <NUM> may have differing dimensions in various embodiments.

Platform <NUM> may be comprised of aluminum, copper, steel, or any other material that is suitable for this purpose. Similarly, cap <NUM> may be comprised of aluminum, copper, steel, or any other material that is suitable for this purpose.

Recessed tray <NUM> may include walls <NUM> which are flared inward from their upper edges. Walls <NUM> may prevent coals or other heating elements from sliding or otherwise moving around within heating chamber <NUM> during adjustment by users. The inward flare of walls <NUM> may further promote airflow within heating chamber <NUM> by channeling air toward the heating elements. In the example embodiment, recessed tray <NUM> has a star configuration with eight points. Other embodiments may incorporate other shapes without departing from the scope of the invention. It has been discovered, however that the eight-pointed star configuration provides benefits over other shapes, including benefits of even heating and air flow, particularly when combined with the multi-chambered bowl described herein.

Circumferential vents <NUM> may comprise alternating spaces between vertical protrusions <NUM>. The inner surface <NUM> of each vertical protrusion <NUM> may create a substantially "V" shape with the point directed inward, toward the center of heating chamber <NUM> from the circumferential vents <NUM> on either side of the vertical protrusion. Accordingly, air may be channeled toward heating elements on recessed tray <NUM>. Additionally, the point of each "V" may correspond with each star point of recessed tray <NUM>. It has been discovered that embodiments utilizing such an arrangement benefit from the created air channels which may promote circulation within heating chamber <NUM> and promote even heating of the coals or other heating elements during use.

Perimeter bowl vents <NUM> may be diamond shaped holes allowing airflow from the interior of heating chamber <NUM> into a bowl. Each perimeter bowl vent <NUM> is preferably located near, such as directly in front of, a circumferential vent <NUM>. This may promote a mixture of cool air from the exterior of the cap <NUM> with heated air from the interior of heating chamber <NUM> such that during inhalation by a user, strictly heated air is not the only air being pulled through the water pipe. An upper surface of plate <NUM> can be a recessed holder to provide stability for a coal, such that the coal will not slide or fall off the upper surface of the plate by accident, as may occur if a user accidentally bumps the water pipe. The recessed holder can also have angled interior surfaces so as to direct airflow around and to and from a coal. The recessed holder can have a uniform flat bottom surface to promote uniform heating of tobacco, or other organic material, below the plate. The upper surface of the plate can have openings around the recessed holder to provide airflow to underlying tobacco, or other organic material, when the plate <NUM> is placed atop a head.

Rim <NUM> may be an outward extension of cap <NUM> from a central axis that allows users to rotate cap <NUM> with respect to platform <NUM>. This may allow for different configurations of adjustable side vents <NUM> with respect to circumferential vents <NUM>, allowing a user to control air flows into and out of heating chamber <NUM>. Rim <NUM> is shown as a series of pointed extensions, attaching to cap <NUM> at protrusions <NUM>. In some embodiments, rim may be insulated such that it may be handled by hand. Although rim <NUM> is shown as circumferentially surrounding cap <NUM>, it should be understood that it may only protrude outward in a single location, in a plurality of locations, or in partial circumferential areas.

A user can place or otherwise couple a platform <NUM> on a rim of a bowl filled with tobacco, shisha or other organic matter already prepared as described above. Then a user can place coals or other combustible material on platform <NUM>. Once the coals or other combustible material are in place, they can be heated by a heat source, for example a match or lighter, before a user places or otherwise couples a ventilated cap <NUM> on platform <NUM>.

A cap can be a ventilated cover for protecting a coal from undesired wind. In some embodiments, the ventilated cover can be monolithic and has air vents at regular intervals around an upper circumference. Air vents can also be provided around a lower circumference of the cover. An outer structure can provide a cool handling location for grabbing, adjusting, or moving the cover, even with a lit, hot coal underneath.

<FIG> illustrate an example embodiment of a ventilated cover 1540a-1540t for use in accordance with at least one embodiment of the present invention. The ventilated cover <NUM> can include upper holes of varying sizes and shapes including diamonds, triangles and others, side ventilation holes <NUM> and a rim <NUM> for adjusting an orientation of cover <NUM>.

In some embodiments, the ventilated cover can be an adjustable structure with inner and outer sections. In such embodiments, inner and outer sections can be rotated with respect to each other in order to adjust the size of the air vents. This allows a user to customize the size of the air vents in varying environmental conditions, such as windy, still, indoor, or outdoor. Keys can also allow users to adjust ventilation covers. Additional description of the features and operation of similar covers is given in the patent and applications incorporated by reference in the cross-references herein.

As shown in the example embodiment a head <NUM>, upward purge valve <NUM> and downstem <NUM> with one or more purge airways <NUM> may be coupled together. First upward purge valve <NUM> can be coupled with downstem <NUM> to form upward purge subassembly <NUM>. In this step, upper purge airways <NUM> are covered by upward purge valve <NUM>. Next, subassembly <NUM> is coupled with head <NUM> to form full upward purge assembly <NUM>. Full upward purge assembly <NUM> has a housing with airways <NUM> that lead upward and outward with respect to downstem <NUM>.
