DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0021] The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventors of carrying out their invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the general principles of the present invention have been defined herein to specifically provide an improved system and method for cannabinoid delivery into beverages.

[0022] For the purpose of this disclosure, the word “a” is defined to mean “at least one/’ The word “cannabis” is defined to mean “any species of the cannabis genus of plants including cannabis sativa, cannabis mdica, cannabis ruderalis, and hemp.” The word “cannabis plant matter” is defined to mean “any portion, in past or whole, cannabinoid, terpene, phytonutrient, chemical, or other compound, either natural, artificial, or synthetic, derived or extracted from a cannabis plant or cannabis plant DNA.” The word “beverage mix” is defined to mean “any ground or powdered beverage flavor, substance, etc. configured to be mixed into water to create a flavored beverage.” The terminology includes the words above specifically mentioned, derivatives thereof, and words of similar import. The word “particle” is defined to mean “any portion of matter, liquid, solid, or gas having volume, density, or mass.” The word “hollow' housing” is defined to mean “any housing, rigid or flexible, of any material configured to hold a substance either permanently or temporarily, such as a container or filter.”

[0023] RECOGNITION OF A PROBLEM

[0024] As well documented, cannabis plant matter is desirable for the cannabinoids that the plant matter contains. The cannabinoids include CBD, THC, as well as other desirable cannabinoids. As companies attempt to offer various means to intake these desirable cannabinoids, one method is through coffee products.

[0025] There are many coffee cannabinoid containing products on the market today, and these products claim to have from 5 mg of CBD to 65mg CBD prior to the brewing process. Testing w'as performed on 10 of these products to determine the cannabinoid levels infused into the beverage after brewing. Testing protocols were established and applied to each test. The testing was performed with standard coffee machines found in the marketplace using standard coffee filters or single use coffee systems for each test, as indicated by each product’s directions. For each test, 8oz of water was used. After brewing, 10ml of the brewed coffee from each test was extracted, secured in a vial, then coded and sent for testing at a leading cannabinoid testing facility, Cannalysis Labs in California. The results were conclusive, minimal CBD in the brewed beverage was detected. Since CBD has no intoxicating effects associated with its intake, the consumers of these products are likely unaware that the cannabinoids, in this case CBD, are not reaching the brewed product or at a significantly reduced level. Similarly, if TCH is the cannabinoid, a lower dosage than indicated is likely being consumed.

[0026] SOLUTION TO THE PROBLEM

[0027] The applicants have concluded that the cannabinoids are not able to penetrate the standard coffee filters or the filters present in the single use coffee systems. Alternatively, the cannabinoids are not being infused into the beverage during the brewing process. Thus, the following disclosure describes various embodiments to solve this problem.

[0028] FIG. 1 is a sectional view of a single use coffee containment system 100 according to an embodiment of the present invention. Referring now to FIG. 1, the single use coffee containment system comprises a hollow housing 102 configured to hold a coffee filter bag 104 containing ground coffee or tea (not shown) as well known in the art. it should be understood, that whole coffee and or tea may also be provided. The term “filter bag” may refer to a filter bag in the traditional sense or any filter structure configured to retain a brewed substance, such as ground coffee or tea. For instance, in some embodiments, the filter is part of the hollow' housing, or integrated into the hollow housing. These variations will be discussed in greater detail below, in other embodiments, any brewed beverage substance, or drink mix, such as hot chocolate, or other powdered drink mixes may replace or be in addition to the ground coffee or tea.

[0029] In one embodiment, a predetermined amount of ground cannabis plant matter 206 at a predetermined size is added to the coffee filter bag 104. The coffee filter bag is constructed of a filter material, such as a mesh, screen, permeable paper, fiber, non-woven fabric, or compostable plastic at a predetermined filter size. The predetermined size of the coffee filter bag is smaller than the particle size of the ground coffee, such that the ground coffee is retained in the coffee filter bag during the brewing process. In one embodiment, the predetermined size of the cannabis plant matter is smaller than the predetermined size of the coffee filter bag, such that the ground cannabis plant matter passes through the coffee filter bag. The term ‘"filter size” is defined as the diameter(s) of the openings of the filter.

[0030] During use, the housing of the single use coffee containment system is pierced in both the top surface and the bottom surface of the housing while hot pressurized water passes through the single use coffee containment system into a cup, herein “beverage,” positioned below the single use coffee system (not shown) as well known in the art. Thus, after brewing, the beverage would contain a coffee and cannabis plant matter (cannabinoid) combination.

[0031] Typically, coffee or tea filters are made up of filaments approximately 20 micrometers wide enabling particles to pass through that are less than approximately 15 to 20 micrometers, preferably 10 to 15 micrometers or less. Thus, in one embodiment, the predetermined size of the cannabis plant matter is less than 10 micrometers. It should be understood, that the coffee or tea filter filaments, or filter size openings may be adjusted (larger or smaller), and likewise, the size of the cannabis plant matter may be adjusted (larger or smaller), such that the cannabis plant mater is smaller than the filter size openings. Further, the coffee or tea provided in the filter may be any size irrespective of the filter size openings. Further, it should be understood, that only a portion of the cannabis plant matter particles of the present invention need to be smaller than the filter size openings.

[0032] In some embodiments, the hollow housing of the system is the filter, such that an additional filter (or filter bag) is not required. This may be referred to the hollow housing having an integrated fiter, in this embodiment, the system may be single-use or reusable, wherein the material selection may vary depending on its usage as well known in the art. In alternative embodiments, other styles of in tegrated filters may be provided, which will be discussed in further detail below'.
