This invention relates to grinding machines suitable for grinding fibrous material, and accessories.
Grinders suitable for reducing herbs, spices, tobacco, and cannabis are known. Those devices typically rely on the rotation of one portion of the grinder against another portion, thereby causing grinding teeth to move past each other to shred the material being ground. Often, the rotating portions must be pressed together to keep the grinding teeth engaged. The pressure that keeps the grinding teeth engaged necessarily increases the friction, both static and dynamic, between the portions of the grinder that rotate against each other. That friction has been addressed by providing contact surfaces of those portions that are as smooth as possible. However, that solution is inadequate. Mechanisms for reducing friction between the portions of the grinder are needed.
Unexpectedly, Applicant has invented new devices and methods that overcome problems found in grinders that have come before. In some cases, a grinder according to the present invention exhibits reduce friction between the portions of a grinder that rotate against each other. In other cases, a grinder having reduced friction has protection against fouling by the material being ground. In still other cases, improved methods for grinding material have been invented. Yet additional cases provide methods for making inventive grinders.
Some embodiments of the present invention provide a grinder, comprising a base having a first plurality of grinding teeth for grinding a fibrous substance, and a lower bearing track encircling the first plurality of grinding teeth; a plurality of bearing elements disposed in the lower bearing track; an upper bearing track in rotational contact with the plurality of bearing elements; and a grinding cap comprising a second plurality of grinding teeth for grinding the fibrous substance, the grinding cap being adapted to contact the upper bearing track so that the grinding cap can be rotated relative to the base wherein the lower bearing track, the plurality of bearing elements, and the upper bearing track reduce friction between the grinding cap and the base.
Further embodiments relate to methods of grinding a fibrous substance, one such method comprising: obtaining a grinder as described herein; placing the fibrous substance between the first plurality of grinding teeth and the second plurality of grinding teeth; rotating the grinding cap relative to the base, thereby causing the first plurality of grinding teeth and the second plurality of grinding teeth to grind the fibrous substance.
Other embodiments of the present invention involve methods of manufacturing the inventive grinders disclosed herein, one such method comprising obtaining the base having the first plurality of grinding teeth and the lower bearing track encircling the first plurality of grinding teeth; disposing the plurality of bearing elements in the lower bearing track; placing the upper bearing track in rotational contact with the plurality of bearing elements; and obtaining the grinding cap comprising the second plurality of grinding teeth; thereby forming the grinder.
Still other embodiments provide containers, one such container comprising a bottom comprising a first plurality of container magnets; a top comprising a second plurality of container magnets; wherein the first plurality of container magnets and second plurality of container magnets align when the bottom is in a closed position relative to the top.

One such herb collection tool comprises a guide channel having an attaching support, the attaching support adapted to attach the herb collection tool to an herb grinder or an herb container.
While the disclosure provides certain specific embodiments, the invention is not limited to those embodiments. A person of ordinary skill will appreciate from the description herein that modifications can be made to the described embodiments and therefore that the specification is broader in scope than the described embodiments. All examples are therefore non-limiting.
As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. The figures are not necessarily to scale, and some features may be exaggerated to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art to which this disclosure belongs. In the event that there is a plurality of definitions for a term herein, those in this disclosure prevail unless stated otherwise.
Wherever the phrase “for example,” “such as,” “including” and the like are used herein, the phrase “and without limitation” is understood to follow unless explicitly stated otherwise. Similarly, “an example,” “exemplary” and the like are understood to be non-limiting.
The term “substantially” allows for deviations from the descriptor that don't negatively impact the intended purpose. Descriptive terms are understood to be modified by the term “substantially” even if the word “substantially” is not explicitly recited.
The term “about” when used in connection with a numerical value refers to the actual given value, and to the approximation to such given value that would reasonably be inferred by one of ordinary skill in the art, including approximations due to the experimental and or measurement conditions for such given value.
The terms “comprising” and “including” and “having” and “involving” (and similarly “comprises”, “includes,” “has,” and “involves”) and the like are used interchangeably and have the same meaning. Specifically, each of the terms is defined consistent with the common United States patent law definition of “comprising” and is therefore interpreted to be an open term meaning “at least the following,” and is also interpreted not to exclude additional features, limitations, aspects, etc. Thus, for example, “a device having components a, b, and c” means that the device includes at least components a, b and c. Similarly, the phrase: “a method involving steps a, b, and c” means that the method includes at least steps a, b, and c.
Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise”, “comprising”, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to”.
Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
As mentioned above, some embodiments of the present invention provide a grinder comprising a base having a first plurality of grinding teeth for grinding a fibrous substance. As can be appreciated by one of ordinary skill in the art, the base can be any suitable shape. In some cases, it is adapted to be held in a person's hand while the grinding operation occurs. That base may have a lower bearing track encircling the first plurality of grinding teeth. That allows a plurality of bearing elements to be disposed or housed in the lower bearing track. The grinder may also contain an upper bearing track in rotational contact with the plurality of bearing elements. In certain instances, the upper bearing track keeps the plurality of bearing elements contained within the lower bearing track. Further, the upper bearing track rotates over the bearing elements relative to the lower bearing track and the base. The grinder also has a grinding cap comprising a second plurality of grinding teeth for grinding the fibrous substance. The pluralities of grinding teeth are arranged in any suitable geometry. In some embodiments, the grinding teeth describe an unobstructed circular path so the base and the grinding cap can freely rotate relative to each other. In other embodiments, the grinding teeth describe an arcuate path, not necessarily a complete circle. The grinding cap is adapted to contact the upper bearing track in certain instances so that the grinding cap can be rotated relative to the base, and the lower bearing track, the plurality of bearing elements, and the upper bearing track reduce friction between the grinding cap and the base. Friction is reduced, in some instances, relative to known grinders where portions of the grinders contact and rotate against each other. The present invention, in certain embodiments, imposes a bearing race comprising a lower bearing track, an upper bearing track, and a plurality of bearing elements disposed therein to reduce the static and dynamic friction between those portions.
In some cases, one or more bearing seals protect the bearing elements from fouling or contamination. For example, some grinders of the present invention contain an inner bearing seal proximal to the upper bearing track and adapted to reduce contact between the fibrous substance and the plurality of bearing elements. As used herein, “inner” and “outer” describe location relative to the grinding teeth. An inner bearing seal is closer to the grinding teeth; an outer bearing seal is further from the grinding teeth. Accordingly, a grinder may further comprise an outer bearing seal proximal to the upper bearing track and adapted to reduce contact between the fibrous substance and the plurality of bearing elements.
Any suitable bearing elements can be used in the various embodiments of the present invention. Those bearing elements may be, for example, ball bearings, right cylindrical bearings, conical bearings, truncated conical bearings, or a combination of two or more thereof. Furthermore, they may be made of any suitable material, such as, for example, metals such as aluminum, steel, stainless steel, or any suitable alloy; glass; ceramic; polymer; polished stone; wood; and combinations thereof. Optionally, the bearing elements can be accompanied by one or more lubricants, such as, for example, graphite, silicon dioxide powder, grease, oil, or combinations thereof. Or, the bearing elements can function without any lubricant.
It can be advantageous in certain instances to keep the grinder “closed.” Thus, some grinders include an upper bearing track comprising an upper lock structure, and a lower bearing track comprising a lower lock structure, wherein the upper lock structure engages the lower lock structure to keep the upper bearing track in rotational contact with the plurality of bearing elements disposed in the lower bearing track. Other grinders include one or more magnets disposed between the base and the grinding cap to connect the grinding cap to the base when the grinder is not in use.
Some grinders further comprise a container for storing ground or unground material. Accordingly, some grinders include a first container adapted to attach to the base opposite the grinding cap. The container can be separate from the grinder, meaning material cannot pass from the grinder to the container. Or, in certain instances, the base of the grinder may comprise a plurality of base openings adapted to allow the fibrous substance to pass through the base to the first container as the fibrous substance is ground. Base openings can have the same or differing sizes, and the same or different shapes. Circles, squares, rectangles, star-shapes, triangles, polygons, leaf shapes, and the like, singly or in combinations, may be mentioned. Any suitable sizes can be used for base openings. For example, base openings can have a dimension such as diameter of less than about 0.100″, less than about 0.200″, less than about 0.300″, less than about 0.400″, or less than about 0.500″. For another example, base openings can have a dimension such as diameter of at least about 0.100″, at least about 0.200″, at least about 0.300″, at least about 0.400″, or at least about 0.500″.
Containers can attach to the grinder in any suitable manner. For example, the first container can be adapted to attach to the base with at least one first connection mechanism chosen from a locking flange, a container magnet, and a threaded interface, and combinations thereof. If desired, a locking flange comprises a rotational stop. That allows rotation of the container relative to the grinder to come to a full stop, and provides security against the container opening inadvertently. If desired, more than one container can attach to a grinder of the present invention. For example, in some cases, a grinder includes a second container adapted to attach to the first container opposite the base. The additional containers can be separate from other containers, or they can be adapted to allow material to pass from the grinder or another container. For example, a grinder comprising two containers can further include a mesh screen disposed between the first container and the second container. Any suitable mesh size can be employed. For example, the mesh screen can be describes as having a mesh size of less than about 100 μm, less than about 150 μm, less than about 150 μm, less than about 200 μm, less than about 250 μm, less than about 300 μm, less than about 350 μm, less than about 400 μm, less than about 450 μm, less than about 500 μm, less than about 550 μm, less than about 600 μm, less than about 650 μm, less than about 700 μm, less than about 75 μm, less than about 800 μm, less than about 850 μm, less than about 900 μm, less than about 950 μm, or less than about 1000 μm. For another example, the mesh screen can be describes as having a mesh size of at least about 100 μm, at least about 150 μm, at least about 150 μm, at least about 200 μm, at least about 250 μm, at least about 300 μm, at least about 350 μm, at least about 400 μm, at least about 450 μm, at least about 500 μm, at least about 550 μm, at least about 600 μm, at least about 650 μm, at least about 700 μm, at least about 75 μm, at least about 800 μm, at least about 850 μm, at least about 900 μm, at least about 950 μm, or at least about 1000 μm. Moreover, the second container can be adapted to attach to the first container, for example. Any suitable connection mechanism can be employed. In some cases, a second connection mechanism is chosen from a locking flange, a container magnet, and a threaded interface, and combinations thereof.
Any suitable materials can be used to form the grinders and the components thereof of the present invention. For example, stainless steel, aluminum, polymer, stone, wood, or a combination of two or more thereof may appear.
As described herein, applicant has invented methods of grinding a fibrous substance. Any suitable fibrous substance may be ground in one or more of the various grinders described herein. Among fibrous substances, herbs, spices, tobacco, and cannabis may be mentioned. One such method of grinding involves obtaining a grinder as described herein; placing the fibrous substance between the first plurality of grinding teeth and the second plurality of grinding teeth; and rotating the grinding cap relative to the base, thereby causing the first plurality of grinding teeth and the second plurality of grinding teeth to grind the fibrous substance.
Applicant has also developed methods of manufacturing grinders and the components thereof. One such method includes obtaining the base having the first plurality of grinding teeth and the lower bearing track encircling the first plurality of grinding teeth; disposing the plurality of bearing elements in the lower bearing track; placing the upper bearing track in rotational contact with the plurality of bearing elements; and obtaining the grinding cap comprising the second plurality of grinding teeth; thereby forming the grinder.
Applicant has also invented certain containers. One such container includes a bottom comprising a first plurality of container magnets; a top comprising a second plurality of container magnets; wherein the first plurality of container magnets and second plurality of container magnets align when the bottom is in a closed position relative to the top. Magnets align when there opposite poles are in close proximity manifesting an attractive force between them. Such containers may also include a locking flange that locks when the bottom is in the closed position relative to the top. The locking flange may include any desirable structure. In some cases, the container comprises a plurality of locking flanges disposed on the bottom, and a plurality of grooves on the top adapted to receive the plurality of locking flanges. In other cases, the container comprises a plurality of locking flanges disposed on the top, and a plurality of grooves on the bottom adapted to receive the plurality of locking flanges. In still other cases, the container comprises one or more first locking flanges disposed on the top and one or more first grooves disposed on the bottom and adapted to receive the one or more first locking flanges; one or more second locking flanges disposed on the bottom and one or more second grooves disposed on the top and adapted to receive the one or more second locking flanges. In still other cases, it can be said that two locking flanges interact with each other to secure two components together.
As mentioned herein, applicant has invented certain grinders, one such grinder includes a base having a first plurality of grinding teeth for grinding a fibrous substance, and a lower bearing track encircling the first plurality of grinding teeth; an upper bearing track; a plurality of bearing elements disposed in the upper bearing track, wherein the upper bearing track and the plurality of bearing elements are disposed in rotational contact with the lower bearing track; a grinding cap comprising a second plurality of grinding teeth for grinding the fibrous substance, the grinding cap being adapted to contact the upper bearing track so that the grinding cap can be rotated relative to the base wherein the lower bearing track, the plurality of bearing elements, and the upper bearing track reduce friction between the grinding cap and the base.
Yet additional grinders affix the upper bearing track to the grinding cap, while the lower bearing track remains affixed to the base. Bearing elements can be disposed in the upper bearing track, the lower bearing track, or both. See, e.g.,
Still other inventive methods relate to methods of reducing rotational friction between a first surface and a second surface that rotate against each other in a contaminating environment, one such method comprising: interposing a bearing race between the first surface and the second surface, wherein the bearing race comprises a plurality of bearing elements in rotational contact with a first bearing track and a second bearing track, and wherein the first bearing track and second bearing track shield the plurality of bearing elements from contamination from the contaminating environment, thereby reducing rotational friction between the first surface and the second surface. In some cases, the first bearing track is affixed to the first surface. In further cases, the second bearing track is affixed to the second surface. The plurality of bearing elements can be disposed in the first bearing track, the second bearing track, or both.
Methods of sealing a bearing race have also been invented. As used herein, “seal” and “sealing” indicate protecting bearing elements from contamination or fouling from the material being ground. The seal need not be hermetic or fluid-proof, but it can be in certain instances. One such method includes providing a bearing race having a first bearing track, a second bearing track, and a plurality of bearing elements between the first bearing track and the second bearing track; and establishing an inner bearing seal and an outer bearing seal on the first bearing track to seal the plurality of bearing elements. Optionally, a single bearing seal, such as an inner bearing seal, can be employed in certain examples of the present invention. Further, one or more bearing seals can appear on the second bearing track as well.
Applicant has also invented herb collection tools. One such tool comprises a guide channel having an attaching support, the attaching support adapted to attach the herb collection tool to an herb grinder or an herb container. The herb collection tool can be attached to any suitable herb grinder or herb container. In some cases, a suitable herb grinder is a grinder described herein. In further cases, a suitable herb container is a container described herein. The herb collection tool can connect to an herb container or herb grinder using any suitable mechanism. In some cases, a suitable connection mechanism is a tool locking flange, a tool groove to receive a locking flange, a tool magnet, a tool threaded interface, or a combination thereof. A tool locking flange may comprise a rotational stop. A tool groove may comprise a rotational stop. When a plurality of tool locking flanges or a plurality of tool grooves appear, the plurality may include at least one rotational stop. Certain instances of the present invention provide a connection mechanism that includes a tool locking flange or a tool groove in combination with a tool magnet.
Sometimes, the herb collection tool can be used to funnel ground herb from a herb grinder or a herb container into another vessel along the guide channel. In other cases, the herb collection tool is used as a scooper to shovel ground herb out of the herb grinder or herb container. Certain instances provide a guide channel that terminates in a scraper edge distal from the attaching support.
The herb collection tool also can be used to manipulate the ground herb or other ground material after removal from the herb grinder or herb container. If the guide channel or other portions of the herb collection tool prove inadequate for the desired manipulation, additional features may be present on the tool. For example, one or more picks can be used to pack the ground material in another vessel, such as, for example, a pipe. If more than one pick is present, the several picks can be of different sizes and shapes. In some cases, the picks are conical, terminating in a rounded or flat head. The terminal end can be of any suitable dimension to accomplish the desired manipulation(s). In certain instances, two conical picks of different terminal diameters affixed to the attaching support. A terminal diameter indicates the width of the pick at the tip furthest from the rest of the herb collection tool.
The herb collection tools of the present invention can have any suitable shape and size. In some cases, nonetheless, the attaching support describes an arc of a circle. That arc will help the herb collection tool to attach to circular or partially circular herb grinders and herb containers
Herb collection tools can be made of any suitable material. In some cases, a herb collection tool as described herein comprises stainless steel, aluminum, polymer, stone, wood, or a combination of two or more thereof.
Further embodiments of the present invention can be described by reference to the accompanying drawings.
Grinder 100 further comprises first container 210 adapted to attach to base 110 opposite grinding cap 160. Grinder 100 also comprises locking flange 224 to allow first container 210 to attach to base 110. Grinder 100 further comprises another first connection mechanism chosen from a plurality of container magnets 242, 244, 252, 254. Container magnet 244 fits into container magnet holder 234 and engages container magnet 254 which is disposed in base 110. Container magnet 242 fits into container magnet holder 232 and engages container magnet 252. Screen 320 separates first container 210 from second container 310.
