The present invention relates to smoking wrappers, and more particularly to a smoking wrapper based on the leaf of ramon tree (Brosimum Alicastrum), and method of manufacturing thereof.
Currently, there are several smoking options available, such as pipes, cigars, vaporizers, hubble-bubble, better known as “hookah”, water pipes, better known as “bongs”, among others. The most common way of smoking is by means of cigarettes, blunts, or cigars which allow wrapping a normally dry leaf with paper. Cigarettes usually have filters that allow the toxic particles in the smoke to be reduced.
In recent years, the use of alternative cigarettes, i.e., cigarettes based on different ingredients, has become commonplace due to the harmful effects of traditional cigarettes, i.e., tobacco cigarettes, and the recently legalized Cannabis plant. Usually, alternative cigarettes use rolling papers, made from wood pulp, rice straw, flax, hemp, cotton fibers, among others. However, the smoking papers currently used tend to burn quickly, so cigarettes often have a short duration. In addition, the manufacturing methods for wood pulp or cotton-based smoking papers are often complicated due to the raw material and machinery used.
A particular example of proposed prior art solutions for smoking wrappers is disclosed in RU1836037C, which relates to a paper wrapper containing a fuel cell surrounded by an insulating layer, wherein the paper is treated with a flame retardant, said flame retardant being selected from calcium chloride, ammonium chloride, magnesium chloride, magnesium sulphate, ammonium sulphate, and sodium phosphate. The wrapper contains additives selected from hydrated silicon dioxide and a binder. However, the wrapper disclosed in said document contains products that are harmful to health and has a high production cost due to the reagents used.
Another specific example is U.S. Pat. No. 6,138,684A, which relates to a rolling paper for smoking containing calcium carbonate in particulate form (30 to 60 wt %), calcined clay (5 to 30 wt %), and pulp. In addition, it may contain an alkali metal salt as a chemical additive. The paper may also contain kaolin. However, the rolling paper disclosed herein comprises several chemical additives which may be harmful to the health of consumers.
Likewise, another example is disclosed in U.S. Pat. No. 7,677,256B2, which relates to a smoking wrapper comprising: a base sheet possessing a major surface; a primary underlayer printed continuously over the entire major surface of the base sheet; a plurality of bands applied over the major surface of the base sheet in the form of a pattern; each band possessing at least two layers; the at least two layers including a bottom layer applied to the major surface of the base sheet over the primary underlayer, and an upper layer applied to the bottom layer. In addition, at least one of the layers includes a film-forming material selected from polyvinyl alcohol, ethylcellulose, sodium alginate, ammonium alginate, pectin, nitrocellulose, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, cellulose acetate propionate, ethylene vinyl acetate, guar gum, xanthan gum, starch, and polyvinyl acetate. However, the method of manufacturing the smoking wrapper material disclosed herein proves to be complicated and expensive because it comprises several layers. Moreover, reagents are used which, when burned, generate toxic residues for consumers and the environment.
Accordingly, we have sought to overcome the disadvantages of the currently used smoking wrappers by developing a completely natural smoking wrapper that does not contain additives or chemical reagents that are harmful to health, or glues. In addition, the smoking wrapper is required to contain natural fiber, proteins, vitamins A, B, C and E. Likewise, the smoking wrapper is required to be manufactured using a green method, by not using environmentally harmful reagents, be economical and not require expensive machinery, so that the cost of obtaining the smoking wrapper is low, making it a cost-effective product and easily accessible to consumers.
Considering the defects of the prior art, it is an object of the present invention to develop a smoking wrapper based on the leaf of ramon tree (Brosimum alicastrum), which is completely natural, based on the leaf of ramon tree (Brosimum alicastrum), does not contain additives, nor reagents harmful to health or glues.
Another object of the present invention is to provide a smoking wrapper based on the leaf of ramon tree (Brosimum Alicastrum) which is obtained through a green manufacturing method, i.e., which does not use environmentally harmful reagents.
It is still another object of the present invention to provide a smoking wrapper based on the leaf of ramon tree (Brosimum Alicastrum) which is easily accessible to consumers as it does not require expensive machinery, nor reagents that are difficult to access in its manufacture.
Another object of the present invention is to provide a smoking wrapper based on the leaf of ramon tree (Brosimum Alicastrum) with burn times similar to those of conventional smoking wrappers.
Lastly, it is an object of the present invention to provide a method of manufacturing a smoking wrapper based on the leaf of ramon tree (Brosimum Alicastrum) which is easily scalable and where neither consumers nor producers are exposed to reagents harmful to their health.
These and other objects are achieved by a smoking wrapper based on the leaf of ramon tree (Brosimum Alicastrum) and method of manufacture according to the present invention.
Accordingly, the present invention provides a smoking wrapper based on the leaf of ramon tree (Brosimum Alicastrum) comprising at least one base layer formed by leaves of ramon tree.
