With the space filled, a solid smokable cylinder of pulverized leaf, which does not require a wrapper to remain intact, is created.

Description

A SMOKABLE PULVERIZED LEAF STRUCTURE

TECHNICAL FIELD

The invention generally pertains to tobacco or other substance smoking devices, and more particularly to a wrapper-less smokable structure made of a pulverized leaf substance.

BACKGROUND ART

Although smoking cigarettes and other tobacco products is on the decline, there are many people throughout the world who still smoke. In the United States and certain other countries it is anticipated that a previously illegal leaf product will soon be legalized for smoking or other uses. In some countries it is already legal.

One of the most predominant concerns of people who smoke manufactured cigarettes is that multiple additives, some of which are harmful to a person's health, are present in the cigarettes. The possibility that this will occur when the currently illegal substance is legalized is also a concern too smokers. Many smokers feel that the optimal smoking experience occurs when using a pure pulverized leaf substance preferably in a pipe which removes the need for any type of wrapper.

Typically, a wrapper is made of paper, which is known as cigarette paper, and is used to maintain the tobacco or other pulverized leaf substance in a tube-like structure for smoking. All manufactured cigarettes utilize a wrapper, and people who "roll their own" cigarettes also use a wrapper. The only purpose of the wrapper is to maintain the tobacco or pulverized leaf in cohesive structure that can be lit and inhaled from. It would be extremely beneficial to provide a smokable structure that does not require a wrapper and is made entirely of pulverized leaf. Optimally, the structure would allow manufactured cigarettes to be provided without a wrapper, and would allow individuals to provide their own wrapper-less cigarettes when desired. A wrapper-less pulverized leaf smokable structure would also preferably be made of one hundred-percent (100%) pulverized leaf, without any additives or chemicals, which are typically extremely harmful.

A search of the prior art did not disclose nay literature or patents that read directly on the claims of the instant invention. However, the following U.S. patents are considered related:

DISCLOSURE OF THE INVENTION

In its basic design the smokable pulverized leaf structure is comprised of a smokable cylinder made entirely of one hundred-percent (100%) pulverized leaf, and a mold for producing the smokable cylinder. The one hundred-percent (100%) pulverized leaf can consist of any smokable leaf such as tobacco or cannabis. The mold comprises a plurality of plates that are maintained together in a geometric form by at least one strap. A rod is inserted into the mold and then a quantity of pulverized leaf is poured into the mold. Once the leaf is within the mold, a press is utilized to apply pressure around the mold, thus compessing the pulverized leaf within. After the pressure is applied, the rod is removed. Additional pulverized leaf is then inserted into the space created when the rod was removed. With the space filled, a solid smokable cylinder is created. If desired a filter can be attached to either end of the smokable cylinder.

In an alternate design, for greater manufacturing quantity, a mold can be made that produces an elongated smokable cylinder. Whatever desired length of each smokable cylinder can then be cut from the elongated cylinder.

The benefits of the structure are that either individuals or companies can use the inventive concept to produce a smokable structure. The mold could be sold as a single unit to an individual for making smokable cylinders at home, or the mold design could be adaptable to large-scale production of smokable cylinders. When used at home, a person can be sure that the pulverized leaf they are using is one hundred-percent (100%) free of additives and/or chemicals.

In view of the above disclosure the primary object of the invention is to produce a smokable pulverized leaf structure that allows a wrapper-less smokable cylinder of pulverized leaf to be quickly and easily created. In addition to the primary object of the invention, it is also an object of the invention to produce a smokable pulverized leaf structure that:

• utilizes a mold that is easy to use,

BEST MODE FOR CARRYING OUT THE INVENTION

The best mode for carrying out the invention is presented in terms that disclose a smokable pulverized leaf structure, as well as steps for producing the structure. There have long been objects that facilitate the smoking of a crushed or pulverized leaf substance. These objects include pipes, wrapping paper (which is also known as cigarette paper) and, in the case of a cigar, a tobacco leaf wrapper. Rolled cigarettes became and are still the most widely utilized object for smoking tobacco and other leaf substances. This is because cigarettes, whether manufactured or self-rolled, are a quick and convenient facilitates for smoking. Many people though would prefer to smoke a leaf substance in a pipe in order to enjoy just the leaf substance without the paper wrapper.

The structure disclosed herein provides an alternative that offers the convenience of a cigarette without the paper or any other type of wrapper. The smokable structure allows a smoker to inhale only the leaf substance and to know exactly what is added to, or not added to, the leaf substance. This is important because manufactured cigarettes have multiple additives, many of which are deemed harmful to a person's health. The structure is primarily used for smoking pulverized tobacco or cannabis, but other smokable leafs can also be used including amaranthus dubius, arctostaphylos uva-ursi (bearberry), arnica, damiana, eschscholzia californica, humulus luplus, lobellias, opium poppy, salvias, sida acuta, syzygium aromaticum (clove), verbascum, and zornia latifolia

The structure 10, as shown in FIGURES 1-10, includes a smokable cylinder 12, and a mold 26 that facilitates the manufacture of the smokable cylinder. Methods for utilizing the mold 26 are also disclosed. The smokable cylinder 12 comprises an outer surface 14, a first end 16 and a second end 18. In the preferred embodiment, the smokable cylinder 12 is made entirely of a pulverized leaf 22 substance, as shown in FIGURE 1. Additionally, while the structure is preferably cylindrical, any geometric shape can be produced.

In order to create the smokable cylinder 12, the mold 26 is utilized. As shown in FIGURES 2-7, the mold 26 is preferably comprised of four plates 28 which are made of a hard material such as metal or plastic. The dimensions of the plates 28 can vary depending on the desired size of the smokable structure 12.

The four plates 28 are rectangular shaped and are placed adjacent to each other, thereby forming a rectangle with an upper surface and a lower surface consisting of the four plates 28. It should be noted that while four rectangular plates are preferred, other embodiments utilizing multiple plates of various geometric shapes can also be effectively used.

At least one strap 30 is placed around the plates 28 to maintain the shape and position of the plates. The strap 30 can be made of any durable material, and the length of each strap 30 is determined by the dimensions of the plates 28. Once at least one strap 30 is in placed around the plates 28, a first opening 32 is created preferably by drilling longitudinally down through the center of the upper surface of the plates 28, wherein the center is the location where the four plates 28 intersect. In an alternate design, each of the four plates has a corner section cut into a 90-degree arc 54, as shown in FIGURE 8. When the four plates are placed together and the four cut corner sections intersect, a 360-degree circular opening is created. Also, only two plates could be utilized, with each plate having a 180-degree arc 56, as shown in FIGURE 9.

A second opening 34 is created at the lower surface/base of the plates. A solid metal rod 36 is inserted into the second opening 34. The dimensions (diameter) of both the solid rod and second opening can vary depending on desired thickness of the smokable structure. Once these steps are completed, the mold 26 is created.

A funnel 42 is utilized to pour the pulverized leaf 22 into the mold 26 via the opening. The funnel 42 can be either integrally attached to the mold 26, as shown in FIGURE 4, or the funnel 42 can be a separate component that is placed above the opening for use, as shown in FIGURE 5. During this process the mold 26 can be vibrated to ensure the pulverized leaf 22 completely fills the mold 26.

Once the mold 26 is filled with the pulverized leaf 22, the mold is placed on a press. The press consists of a hollow tube 38. The press is designed so that the hollow tube 38, which is made of hard material such as metal or plastic, fits between the mold 26 and the solid rod 36. Once the hollow tube 38 is in place, pressure is applied around the mold 36, either manually or by mechanical/powered means, thereby compressing the pulverized leaf 22.

After pressure is applied and the pulverized leaf is compressed, the solid rod 36 is removed from the center of the mold 26. At this point, a hard shell 44 of compressed pulverized leaf is left within the mold 26. If desired at this point, to increase the structural integrity of the smokable structure, a binding agent 46 (not shown) such as wax or an oil can be applied to the shell of pulverized leaf.

Continuing, a hollow tube 38 is placed above the shell 44, as shown in FGURE 7. The hollow tube 38 is filled with additional pulverized leaf. A solid tube rod 40 is then inserted into the hollow tube 38. The solid tube rod 40 is pushed downward thereby forcing the pulverized leaf within the hollow tube 38 into the shell 44, thereby creating a solid smokable structure 12, as shown in FIGURE 1.

The strap(s) 30 are then removed and the plates pulled off, thereby opening the mold 26 and revealing the smokable cylinder 12 in the form of a solid rod of pulverized leaf. If desired, an additional, or first, binding agent can be applied to the outer surface 14 of the smokable structure. A person can now light either the first end 16 or the second end 18 of the smokable cylinder 12 and inhale, as with a conventional paper- wrapped cigarette.

The above disclosed steps are the preferred method of producing the smokable cylinder. There are other methods and/or embodiments contemplated which are equally effective for producing a smokable cylinder. For example, a two-piece mold made of a resilient material that comprises and opening therethrough. In this design, the pulverized leaf substance is inserted into the opening and pressure is applied. There is no center rod within the opening. Preferably a binding agent is utilized to increase the smokable structure's ability to maintain circular shape. And, while a circular shape smokable structure is preferred, the invention is not limited to this shape. Any geometric shape smokable structure can be created by altering the shape of the opening in the mold.

In another alternate method, instead of utilizing a multi-component mold that is opened after pressure is applied, a mold that allows a smokable structure to be manually or automatically pushed outward from the opening and cut at a desired length can be utilized. This type of mold could be made in a relatively larger size to produce a single smokable structure that can be cut at various locations to product multiple smokable structures.

And, in a final alternate method, the pulverized leaf is ran through a screen, which can be of various mesh sizes to allow for uniformity of and various sizes of leaf to be produced and utilized. After the leaf passes through the screen, a binding agent is applied to maintain the shape and integrity of the final smokable cylinder. One of the pre-disclosed mold designs is utilized, with the components of the mold that come into contact with the leaf, coated with Teflon or a similar substance that will reduce sticking of the leaf to the components. The pulverized leaf is inserted into the mold via a funnel and an auger applies downward pressure. By this method, various amounts of pressure can be applied to the pulverized leaf. Heat is then 8

9 applied, which hardens the pulverized leaf, thereby creating a smokable cylinder with a hard outer shell/surface when the leaf is extruded.

To add to the utility and improve the smoking experience for some people, a mouthpiece 50, as shown in FIGURE 10, can be utilized. The mouthpiece 50 is preferably also made of a pulverized leaf 22 substance, and consist of a cylindrical tube that is preferably hardened with a binding agent. The mouthpiece 50 is dimensioned to fit onto and be frictionally maintained on one end of the smokable cylinder. The mouthpiece 50 can be utilized as a hollow design, or a smokable non-pulverized piece of leaf can be wrapped around a filter and attached to the smokable cylinder 12. Additionally, a conventional cigarette mouthpiece holder, which is typically made of a material such as plastic, a paper or composite material can be utilized.

And finally, an outer covering can be utilized to protect the pulverized leaf structure prior to use, during transportation, or when displayed for sale. Preferably, the covering is made of transparent plastic, although other material such as paper can also be used. The pulverized leaf structure can be presented and sold (where legal) individually, or a quantity of pulverized leaf structures can be placed in a box (such as a pack of cigarettes) or in a cigar-type box.

While the invention has been described in detail and pictorially shown in the accompanying drawings it is not to be limited to such details, since many changes and modification may be made to the invention without departing from the spirit and the scope thereof. Hence, it is described to cover any and all modifications and forms which may come within the language and scope of the claims.
