The present invention is in the technical area of cannabis product preparation and storage, and pertains more particularly to an adapter for joining a cannabis herb grinder to a Mason jar, to shred cannabis leaves into the Mason jar for protection and storage.
The skilled person will understand that there a many sorts of storage containers that are, and that might be used for storing shredded herb. Such product is stored in zip-lock bags, on occasion in plain jars, and in many other containers. Many such storage solutions, however, do not keep the product from too much or too little moisture, or from other environmental effects that may be detrimental. The inventors have discovered that well-known Mason jars are ideal for shredded herb storage, but that there is a problem with shredding or grinding the herb, and transferring same to the Mason jar for storage. Some herb components may be displaced or lost in the process, and may get scattered or dispersed.
What is clearly needed is a adapter that securely and smoothly joins an herb grinder to a Mason jar.
In one embodiment of the invention an adapter is provided, comprising a circular body having an outer diameter and a height, a counter-bore concentric with the outer diameter, implemented in a lower extremity of the body, having a first inner diameter from the lowest point of the body to an internal horizontal shoulder, a through bore having a second inner diameter concentric with the outer diameter from an upper extremity of the body to the level of the internal horizontal shoulder, a male thread implemented at the upper extremity of the body adapted to engage a female thread of a commercially-available herb grinder, and a course female thread implemented in the counter-bore from the lower extremity of the body to the internal horizontal shoulder, the course female thread of a form to intimately engage threads under a rim of a regular-mouth Mason jar.
In one embodiment of the adapter the second inner diameter of the body of the adapter is about 60 mm, which is the inner diameter of an upper rim of a regular-mouth Mason jar, such that, with the adapter engaged to the Mason jar the inner horizontal shoulder contacts the upper rim of the regular-mouth Mason jar. Also, in one embodiment the body of the adapter is aluminum, and outer surfaces of the aluminum body are black-anodized. In one embodiment the body of the adapter is aluminum, and outer surfaces are anodized to individual ones of several different colors. In one embodiment the outer diameter is greater than 2.5 inches from the lower extremity to at least one-half of the height, and an upper portion above one-half the height is tapered toward a center of the circular body. And in one embodiment the outer diameter of the circular body is textured to provide a sure gripping surface.
In another aspect of the invention a method for catching and storing shredded herb is provided, comprising engaging male threads at an upper extremity of a body of an adapter to compatible internal threads at a lower extremity of a commercially available herb grinder, engaging course female threads implemented in a counter-bore from a lower extremity of the body up to an inner horizontal shoulder to threads under a rim of a regular-mouth Mason jar, such that the rim of the Mason jar firmly contacts the horizontal shoulder of the body of the commercially-available herb grinder, and operating the commercially-available herb grinder, causing shredded herb to fall through the adapter into the regular-mouth Mason jar.
In one embodiment the method further comprises disengaging the course threads of the adapter from the course threads under the rim of the regular-mouth Mason jar, removing the adapter together with the commercially-available herb grinder, and closing the regular-mouth Mason jar with a conventional lid and threaded band.
Largely supplanted by other products and methods for commercial canning, such as tin cans and plastic containers, glass jars and metal lids are still commonly used in home canning. Mason jars are also called Ball jars, in reference to the Ball Corporation, an early and prolific manufacturer of glass canning jars; fruit jars for a common content; and glass canning jars, which is a generic term reflecting their material and purpose. The present inventor considers that quality of hermetic sealing to be advantageous for keeping shredded herb fresh and flavorful.
Mason jar 101 in this example is a regular-mouth jar with a molded-in thread system 104A that is particular and common to all regular-mouth-mouth Mason jars regardless of brand and manufacture. A regular-mouth Mason jar has an inside diameter at the mouth of 2⅜ inches (60 mm), and an outside diameter at the rim of 2¾ inches (70 mm). A wide-mouth Mason jar (not shown) has an inside diameter at the mouth of 3 inches (76 mm), and an outside diameter at the rim of 3⅜ inches (86 mm).
The molded male thread 104A is a very course thread, as may be seen, requiring about two turns to fully engage a standard rim. A commercially-available grinder 103 is shown in
Grinders are typically shown assembled to a lower container that is provided for catching and storing shredded herb. These storage containers are typically not hermetically sealed or even partially airtight. Grinder 103 of
Between the Mason jar and the grinder an Adapter 102 is shown, specifically adapted to engage the herb grinder 103 to the Mason jar 101. Adapter 102 has a male thread 105A of about 2 inch OD, compatible with female tread 105B of the grinder. Adapter 102 has an inner diameter from an upper extremity down to a shoulder 107 the same as the inner diameter of the Mason jar, which is 2/⅜ inches (60 mm). Downward from shoulder 107 inside the adapter, as shown in partial section, is a female thread 104B compatible with male thread 104A at the upper extremity of the Mason jar.
In practice of the invention a user will typically engage grinder 103 with adapter 102 by engaging threads 105A and 105B, then, with lid 107 open, load herb into the grinder. Then the user closes lid 107, and engages adapter 102, with the loaded grinder engaged, to Mason jar 101. The user may then rotate lid 107, shredding herb that was previously loaded, with shredded herb falling into the Mason jar. The grinder may be reloaded and operated as many times as desired, and when finished, or when the Mason jar is full, the adapter, with grinder, may be disengaged from the Mason jar, which may be closed with a conventional sealing lid and sealed with a conventional threaded band. One important aspect of the adapter, when engaged with the herb grinder 103 and the mason jar 101, is that when tightened, a smooth, flush surface inner wall is provided from the grinder to the jar so that no particulate matter is caught or retained in any seams where the herb grinder meets the adapter and where the adapter meets the jar.
Adapters such as 102 shown may be manufactured of aluminum and black anodized aluminum or stainless steel, for example. Other materials may be used for manufacturing the adapter 102, including hardened plastics, and composite materials such as those using carbon fiber and fiberglass reinforcements in plastics and epoxy material. Other reinforced plastic material may include polyester, vinyl ester, and other thermosetting resins used for glass-reinforced plastic.
Other colors such as gold and blue may be provided in anodized aluminum as well. Other materials may be used, like high molecular count polymers for example, in many different colors. Other metals may be used, such as titanium for example. There may be different textures applied to the outer surface of adapters as aid for a user's grip, or in some cases just for aesthetic effect. In some cases a user may elect to use a rubber-like seal between the mason jar and the adapter. There are many possibilities.
Another embodiment provides an adapter wherein a grinder may be attached to the adapter by means other than implementing male and female threads. For example, the grinder may have a supple skirt of pliable rubber or silicon material fit flush along an interior surface at a location of existing threads 105B (
The skilled person will understand that the embodiments taught in enabling detail herein are, in fact, exemplary, and there may well be other variations, not discussed in detail, that will still lie within the scope of the invention. An adapter of the sort taught herein may have different threads at the upper extremity to accommodate grinders of different make and model. The invention is limited only by the scope of the claims below.
