Abstract

A pliable sheet is manufactured for use with smokable substances. The pliable sheet is completely sourced from female plants of the cannabis genus. Source species include cannabis sativa, cannabis indica, or a blend thereof. A manufacture process entails processing and refining harvested plant material before it can be formed into the pliable sheet. After formation the pliable sheet is dried before it is ready for use. Flavoring and aromatic elements can be incorporated into the pliable sheet to enhance a smoking experience. Adhesives may also be integrated to facilitate rolling of the pliable sheet about smokable matter. Ideally, the adhesives are sticky oil extracts produced from plants of the cannabis genus. The pliable sheet can be manufactured in a variety of thicknesses and sizes.

Description

Wrapper for Enclosing Smokable Substances
The current application claims priority to U.S non-provisional patent application serial number 15/219,061 filed on July 25, 2016 and U.S. provisional patent application serial number 62/245,153 filed on October 22, 2015.
FIELD OF THE INVENTION
The present invention relates generally to a pliable sheet for rolling and wrapping smokable products, the pliable sheet being manufactured from a plant of the cannabis genus.
BACKGROUND OF THE INVENTION
A variety of plant matter is harvested for consumption, with one common method of consumption being the burning of the plant matter and inhalation of the resulting smoke, colloquially referred to as smoking. Generally, to facilitate smoking of such herbs, a thin sheet is used to wrap the herbs into a generally cylindrical sheet. This process is known as "rolling"; while many vendors provide the option to buy pre -rolled products, there is a population of consumers that rolls their own product for a variety of reasons, e.g. reduced cost or improved choice in rolling paper.
A variety of rolling papers are provided for different purposes. Rolling papers can be sourced from a wide range of material; for example, wrapping papers can be manufactured from rice and hemp. Additionally, rolling paper can be provided in a variety of sizes, from the efficiently compact to the comically large (the latter being lambasted in the theatrical film "Up In Smoke". Likewise, the specific type of plant matter being burned is variable, also referenced in the aforementioned film. The wide variety of rolling papers allows for a number of nuances to come into play; wrapping papers derived from different plants affect burn time, flavoring, and ease of wrapping. Additionally, many rolling papers are enhanced with one or more flavoring elements. Resultantly, smokers can sample and enjoy a variety of rolling papers with unique characteristics in combination with their favorite cigarettes, cigars, and so on.
Cigars are commonly wrapped in a tobacco leaf that imparts a specific flavor and experience, especially in combination with the actual blend of tobacco placed within the leaf. Other smokable substances could be enhanced in a similar manner. More specifically, given the legalization of marijuana for medicinal and now even recreational purposes, it is desirable to provide a rolling paper made of marijuana. Though there are rolling papers which are sourced from hemp, it is an object of the present invention to provide a rolling paper that is completely sourced from the marijuana plant. In short, the present invention introduces a marijuana-based sheet which can be utilized for rolling papers and wraps.

DETAIL DESCRIPTIONS OF THE INVENTION All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
The present invention details a wrapper for enclosing smokable substances as well as a method of manufacture therefor. The present invention utilizes material sourced from the cannabis genus (i.e. "marijuana plants" to create a sheet which can be used as a rolling paper or wrapper for smokable substances. The present invention is subsequently described in more detail.
The wrapper created by the present invention comprises a pliable sheet 1, the pliable sheet 1 formed from a plurality of elongated cellulose fibers 2. The plurality of elongated cellulose fibers 2 forms the structure of the pliable sheet 1, with adjacent strands of fiber being effectively glued to each other by glucose bonds. In line with the stated goals of the present invention, the plurality of elongated cellulose fibers 2 is derived from a plant of the cannabis genus 31. More specifically, the plurality of elongated cellulose fibers 2 is derived from a female plant 3 of the cannabis genus 31. The female plant 3 of the cannabis genus 31 is colloquially referred to as a marijuana plant. The female plant 3 is desirable as source material due to the elevated levels of tetrahydrocannabinol (THC) compared to the levels of THC found in the male cannabis plant 31. More specifically, the female plant 3 produces buds, which contain higher levels of THC compared to the stem and leaves. The present invention could potentially be produced from the stem, leaves, or other parts of the cannabis plant 31, but optimally the buds are used in order to maximize THC levels in the wrapper. Overall, the pliable sheet 1 can serve as a marijuana-based rolling paper or wrapper which can be used for rolling marijuana or other herbal blends. The pliable sheet 1 is illustrated via FIG. 1 - FIG. 3.
In different embodiments of the present inventions, different specifies from the cannabis genus 31 may be used for the pliable sheet 1. For example, in one embodiment, the plurality of elongated cellulose fibers 2 is derived from a female plant 3 of the sativa species 32 of the cannabis genus 31. In another embodiment, the plurality of elongated cellulose fibers 2 is derived from a female plant 3 of the indica species 33 of the cannabis genus 31. In a third embodiment of the present invention, the plurality of elongated cellulose fibers 2 is derived from a first female plant 34 of a sativa species 32 of the cannabis genus 31 and from a second female plant 35 of an indica species 33 of the cannabis genus 31. In this third embodiment, the pliable sheet 1 is effectively created from a blend 36 of the sativa species 32 and the indica species 33, compared to the first two embodiments which are sourced from only a single species of the cannabis genus 31. The term "blend" is used to refer to a strain 37 of the cannabis genus 31 that is bred from the sativa species 32 and the indica species 33. This does not preclude the use of combining plant matter from two different species in order to create the pliable sheet 1. Using a hybrid strain 37 (i.e. bred from sativa and indica) is simply preferable.
The different embodiments described above allow for different profiles to be provided for the wrapper. For example, a pliable sheet 1 sourced exclusively from cannabis sativa 32 will be experienced differently than a pliable sheet 1 sourced from cannabis indica 33. A blend 36 of the two cannabis species will provide yet another profile, which can be further adjusted by varying the ratio of cannabis sativa 32 to cannabis indica 33 in the blend 36.
In one possible embodiment of the present invention comprises an adhesive strip 4. The adhesive strip 4 is connected along an edge of the pliable sheet 1 in order to facilitate rolling and securing of the pliable sheet 1 into a cylindrical shape prior to smoking. Preferably, the adhesive strip 4, as with the pliable sheet 1, is derived from a female plant 3 belonging to the cannabis genus 31, whether of the sativa species 32, indica species 33, or a blend 36 thereof. An oil extract from a plant of the cannabis genus 31 is sticky and thus suitable for creating the adhesive strip 4. Using such a plant-derived oil is preferable as it maintains the cannabis-sourced focus of the present invention; in such an embodiment the present invention is 100% derived from a plant of the cannabis genus 31. An additional benefit of using an oil extract is that the extract is completely natural, being produced from vegetable matter rather than utilizing laboratory created chemical compounds. Though using a cannabis oil for the adhesive strip is preferable, potentially he adhesive strip can be produced from any food safe adhesive. Some examples include, but are not limited to, gum and sugar-derived glues.
In order to maintain the adhesive properties of the adhesive strip 4 prior to use, one embodiment a release liner is provided for the adhesive strip 4. The release liner is a non-stick membrane that is placed over the adhesive strip 4. The release liner prevents the adhesive strip 4 from accidently sticking to another object. The release liner also protects the adhesive strip 4, helping to maintain the latter' s adhesive properties. The release liner has non-stick properties, allowing it to easily be peeled away from the adhesive strip 4. Overall, the release liner protects the adhesive strip 4 during storage (i.e. before being used to secure two ends of a rolling paper).
Potentially, further variety is enabled by infusing the pliable sheet 1 with a flavoring element 5. The flavoring element 5 provides a more sophisticated profile; for example, a cherry-flavored pliable sheet 1 or a rosemary-flavored pliable sheet 1 can be created to enhance the smoking experience with pleasant tastes, smells, or both. The addition of such flavoring elements 5 is an enhancement to the core concept of the present invention, i.e. a fully marijuana derived pliable sheet 1 for wrapping smokable substances. The flavoring elements 5 could be omitted while remaining within the scope of the present invention.
The pliable sheet 1, as earlier stated, can be formed as a rolling paper or wrapper in a variety of sizes. For example, rolling papers can be sized to be single-wide, double- wide, and king-sized. Other sizes, denoted only by dimensions (e.g. a 1 ¼" or 1 ½") are also possible. The thickness of the pliable sheet 1 is also unrestricted by the present invention. Thinner sheets burn slower and impart less taste to the smoking experience. Thicker sheets, conversely, are easier to roll and have superior durability. Both are compatible with the present invention.
Ultimately, a number of alternative embodiments for the pliable sheet 1 remain possible within the scope of the present invention.
A method of manufacture for the wrapper is also provided. The method of manufacture is used to convert a source of provided vegetable matter, specifically of the cannabis genus 31, into a cannabis-derived sheet. As earlier referenced, the harvested vegetable matter is preferably the buds of a female plant 3 of the cannabis genus 31 (whether of the sativa species 32, indica species 33, or blend 36 thereof). The general procedure entails first processing the harvested vegetable matter to extract a supply of cannabis-derived fibers. The cannabis-derived fibers are then separated from each other, resulting in a cannabis-derived pulp. In order to make the cannabis-derived pulp more suited for wrapper formation, it is refined into a cannabis-derived slurry. The cannabis- derived slurry is then transferred to a mold to form a cannabis-derived sheet. Finally, water is extracted from the cannabis-derived sheet, which is then suitable for use as rolling paper or a wrap for smokable substances. Each step of this procedure is described in more detail below, as well as illustrated via FIG. 4 - FIG. 9.
The first step, i.e. processing the harvested vegetable matter in order to produce a cannabis-derived pulp, comminutes the vegetable harvested vegetable matter. That is, the vegetable matter is broken up into individual strands, the group of which is referred to as the cannabis-derived pulp. In order to achieve this, the harvested vegetable matter is passed through a mill in order to grind the harvested vegetable matter into the individual strands. A number of specific machines have been created to facilitate the comminution process, and the present invention does not concern itself with the specific type of machine used; the focus is instead the processing of the harvested vegetable matter to obtain the cannabis-derived pulp. After processing, the comminuted vegetable matter is cleaned via rinsing with an aqueous solution, after which it is ready for refining.
Once the cannabis-derived pulp is created and rinsed, it is refined to be softer.
Softening of the cannabis-derived fibers is traditionally accomplished through mechanical process or water-based processes. The present invention focuses primarily on application of a water-based process, as subsequently described, though this does not preclude the application of mechanical refining or a combination of mechanical and water-based refining.
To refine the cannabis-derived pulp, a heated bath is prepared. The cannabis- derived pulp is then immersed in this heated bath in order to cook and soften the individual strands into a more workable refined pulp. In order to be effective, this cooking stage requires a minimum specified duration. Exact minimum durations vary according to the specifics (e.g. composition) of the bath, but are generally measured in a magnitude of hours. In the preferred embodiment, the heated bath is a solution of sodium carbonate in water. Sodium carbonate is colloquially referred to as soda ash, and it helps to separate cellulose (i.e. the cannabis-derived fibers) from other plant polymers such as lignin. As earlier referenced, mechanical refining can be utilized alongside chemical refining. For example, machine beaters can be provided to help separate the cellulose from the lignin. Too, the present invention is not restricted to the use of a heated bath utilizing sodium carbonate; other solutions can be provided to separate the polymers of the cannabis- derived pulp.
Potentially, a finer level of refinement can be provided by hand; strands can be pulled apart by hand to further separate individual fiber strands from one another. It is possible to continue the refining process beyond this to obtain a desirable size and separation of fiber strands; this extent of refining is ultimately up to the manufacturer and customer demands.
Once the refined cannabis-derived pulp is refined, a cannabis-derived slurry is obtained. This slurry is a mixture of cannabis cellulose in an aqueous solution, such as from the heated bath. This solution is diluted and rinsed by mixing with water, after which it may be placed into a perforated sheet mold. The perforated sheet mold itself is a lattice-style base framed by a wall. The wall outlines the shape of the eventual paper, while the lattice-style base allows for water to be drained from the diluted cannabis- derived slurry. This first entails allowing the cellulose strands to settle at the bottom of the slurry, where glucose bonding begins to form the unitary sheet. After the strands have settled, the perforated sheet mold may be tilted to expedite draining and complete formation of the cannabis-derived sheet.
Once the cannabis-derived sheet has been formed, it is desirable to remove as much water as possible. This is end stage is accomplished through two steps; first, the cannabis-derived sheet is removed from the perforated sheet mold and placed in a press. The cannabis-derived sheet mold is surrounded by absorbent sheets (for example blotting paper or felt pads) on either side. These absorbent sheets serve to collect the water that is pressed out of the cannabis-derived sheet during compacting. This compaction removes a large amount of water from the sheets, but some moisture remains. The final treatment, provided to minimize the remaining moisture in the cannabis- derived sheet, utilizes a dryer. The dryer is simply a fully or partially enclosed heated region into which the cannabis-derived sheet is placed. This heat helps to practically eliminate water from the cannabis-derived sheet, resulting in a pliable sheet which can be used as a wrap for enclosing smokable substances, as originally introduced in this application.
While the above described a core process for manufacture, several optional steps or substitution steps remain possible within the scope of the present invention. For example, flavoring or aromatic elements can be infused into the cannabis-derived sheet, such as by applying a desired element to the cannabis-derived sheet or even immersing the cannabis-derived sheet in such an element.
Likewise, an adhesive coating can be applied along an edge of the cannabis- derived sheet. Such an adhesive coating assists with rolling or wrapping of the sheet about a smokable substance, as the adhesive maintains a cylindrical shape and prevents the rolled sheet from unfurling.
These are just a few examples of additional steps that can be incorporated into the process of manufacture. Ultimately, any variation is suitable as long as it adheres to use of vegetable matter from the cannabis genus for manufacture of a wrapper for enclosing smokable substances.
Although the invention has been explained in relation to its preferred
embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
