Grinders are used to grind organic material into smaller pieces for loading into a device for consumption, such as a combustible cone. Cones are often funnel shaped with a wide top opening and a narrower bottom opening. Filter materials can be placed toward the bottom opening of the cones. Ground material from grinders are often hand loaded into the top opening of the cone. However, it is tedious and messy to transfer ground material from grinders.
The background discussion is intended to provide information related to the present invention which is not necessarily prior art.
The present invention solves the above-described problems and other problems by providing methods of forming apparatuses and apparatuses that enable quick, efficient, and compact loading of ground organic material into a cone.
An apparatus constructed according to an embodiment of the present invention is provided for preparing organic material and loading the organic material into a cone with an end opening. The apparatus comprises a cylindrical body, a grinder assembly, a cone holder, and a funnel. The cylindrical body includes top and bottom openings. The grinder assembly is removably attached to the top opening of the cylindrical body and is configured to grind the organic material. The grinder assembly includes a hole for the ground organic material to pass through. The cone holder extends into the bottom opening of the main cylindrical body and is releasably secured thereto. The cone holder includes an aperture for receiving the cone.
The funnel comprises a wide portion for receiving the ground material that passes through the hole of the grinder assembly and a narrow portion that extends into an end opening of the cone when the cone is held by the cone holder in the cylindrical body. Because the narrow portion of the funnel extends into the end opening of the cone, the ground material falls and is guided right into the cone without losing ground material around the cone within the cylindrical body. Further, because the grinder assembly is removably attached to the top opening of the cylindrical body, the cone can be packed between grinding steps. The inventors have found that due to the sticky nature of certain organic matter, packing a cone once it is completely loaded is difficult as the ground material often remains stuck to the walls. Thus, packing stuck ground material can cause rips in the cone and/or cause the cone to collapse.
A method of forming an apparatus according to an embodiment of the present invention broadly comprises forming a first plurality of engagement threads circumferentially spaced on an upper end of a cylindrical body via computer numerical control (CNC) milling; forming a second plurality of engagement threads circumferentially spaced on a lower end of a grinder assembly via CNC milling; inserting a cone holder into a bottom opening of the cylindrical body; inserting a funnel into a top opening of the main cylindrical body so that a narrow portion of the funnel extends into an end opening of a cone when the cone is held by the cone holder within the cylindrical body; inserting the upper end of the cylindrical body into the lower end of the grinder assembly; and rotating the cylindrical body relative to the grinder assembly so that the first plurality of engagement threads engage the second plurality of engagement threads, thereby releasably securing the grinder assembly to the cylindrical body.
By having a funnel that extends into the end opening of the cone, the ground material is directed into the cone without losing ground material around the cone within the cylindrical body. Further, the engagement threads allow the grinder assembly to be quickly removed and reattached to the cylindrical body so that the cone can be quickly and efficiently packed between grinding. This allows a first layer of the ground material to be quickly packed, which the inventors have found to be essential to reducing heat near the filter. Additionally, by using CNC milling to form the threads, precise formation of the threads is achieved, which avoids jams and allows for consistent reattachment of the grinder assembly.
An apparatus constructed according to another embodiment of the present invention broadly comprises a main cylindrical body, a grinder assembly, a cone holder, and a funnel. The main cylindrical body includes a bottom opening, an upper end defining a top opening, and a first plurality of engagement threads circumferentially spaced on the upper end.
The grinder assembly is removably attached to the top opening of the cylindrical body and is configured to grind the organic material. The grinder assembly includes a grinder cylindrical body, an upper body, a top blade, and a bottom blade. The grinder cylindrical body has a top opening, a lower end defining a bottom opening for receiving the upper end of the main cylindrical body, and a second plurality of engagement threads circumferentially spaced on the lower end for releasably engaging the first plurality of engagement threads. The upper body releasably mates with the grinder cylindrical body. The top blade is secured to the upper body. The bottom blade is secured to the grinder cylindrical body and includes a hole for allowing the ground organic material to pass therethrough.
The cone holder extends into the bottom opening of the main cylindrical body and is releasably secured thereto. The cone holder includes an aperture for receiving the cone. The funnel extends into the top opening of the main cylindrical body and comprises a flange, a wide portion, and a narrow portion. The flange sits on the upper end of the main cylindrical body so that the flange is secured between the grinder assembly and the main cylindrical body. The wide portion opens to the bottom blade of the grinder assembly and is for receiving the ground organic material therefrom. The narrow portion extends into the end opening of the cone when the cone is held by the cone holder.

The upper body 58 releasably mates with the grinder cylindrical body 56. The top blade 60 may be secured to the upper body 58, and the bottom blade 62 may be secured to the grinder cylindrical body 56. The upper body 58 and the grinder cylindrical body 56 may be rotatable relative to one another so that the blades 60, 62 rotate relative to one another to grind the organic material. In some embodiments, a washer 59 may be positioned between the upper body 58 and the grinder cylindrical body 56 and rest on a shoulder 61 of the grinder cylindrical body 56. The bottom blade 62 includes one or more holes 78 for allowing the ground organic material to pass therethrough. The bottom blade 62 may abut the funnel 26 when the funnel 26 is seated on the cylindrical body 20 and the grinder assembly 22 as attached to the cylindrical body 20, as depicted in
The magnetic pin 64 may be secured to the bottom blade 62, and the magnetic pin 65 may be secured to the top blade 60. The magnetic pins 64, 65 may be oriented relative to one another so that their magnetic poles are attracted to magnetically hold the upper body 58 and the grinder cylindrical body 56 together.
The grinder cylindrical body 56 and the upper body 58 may be made of aluminum, aluminum alloy, or the like and formed via CNC milling. The engagement threads 74 may also be formed using CNC milling to enable consistency and uniformity, thereby preventing jams when attaching and removing the grinder assembly 22.

In use, the cone holder 24 may be rotated relative to the cylindrical body 20 so that their engagement threads 40, 86 disengage. The cone holder 24 may then be pulled out of the bottom opening 46 of the cylindrical body 20 with the engagement threads 40, 86 passing by one another through circumferential spaces. The cone 12 may be placed in the aperture 84 through the top end 80 of the cone holder 24 with the filter 18 going in first so that it is positioned away from the top end 80. The cone holder 24 may be reattached to the cylindrical body 20 with the cone 12 held therein by inserting the cone holder 24 with the cone 12 into the bottom opening 46 of the cylindrical body 20 with the cone holder 24 oriented relative to the cylindrical body 20 so that the engagement threads 40, 86 can pass by one another. Once the flange on the bottom end 82 of the cone holder 24 abuts the bottom end 32 of the cylindrical body 20, the cone holder 24 may be rotated relative to the cylindrical body 20 so that their engagement threads 40, 86 engage one another, thereby securing the cone holder 24 to the cylindrical body 20 and the cone 12 within the cylindrical body 20.
The upper body 58 may be removed from the grinder cylindrical body 56 with the top blade 60 attached to the upper body 58. The organic material may be loaded into the grinder cylindrical body 56 and rest on the bottom blade 62 of the grinder assembly 22. The upper body 58 may be placed back on the grinder cylindrical body 56 and rotated relative to the cylindrical body 56 so that the blades 60, 62 grind, tear, cut, and/or shred the organic material so that portions of it fall through the holes 78 of the bottom blade 62 and into the funnel 26. Some of the ground organic material may fall through the narrow portion 90 of the funnel 26 and into the upper wide opening 14 of the cone 12.
The grinder assembly 22 may be removed by rotating the grinder cylindrical body 56 relative to the cylindrical body 20 so that their engagement threads 38, 74 disengage and pulling the cylindrical body 20 out of the lower end 70 of the grinder cylindrical body 56. The packer rod 28 may be inserted into the funnel 26 and used to push some of the ground organic material into the cone 12. The packer rod 28 may be inserted through the narrow portion 90 of the funnel 26 and used to pack the organic material compactly down against the filter 18 of the cone 12. The inventors have found that compacting the organic material proximate to the filter 18 of the cone 12 decreases the temperature of material next to the filter 18, which improves the consumption experience. By being able to efficiently remove the grinder assembly 22, a well packed cone 12 can be produced in a considerably shorter amount of time.
The grinder assembly 22 may be quickly reattached by pulling out the packer rod 28 and inserting the upper end 30 of the cylindrical body 20 into the lower end 70 of the grinder cylindrical body 56. The cylindrical body 20 and the grinder cylindrical body 56 may be rotated relative to one another so that their engagement threads 38, 74 engage one another, thereby resecuring the grinder assembly 22 to the cylindrical body 20. The organic material can continue to be grinded in the grinder assembly 22, and the grinder assembly 22 can be periodically removed for further packing. The inventors have discovered that due to the tacky oils present in some organic material, the organic material tends to stick to the walls of the cone 12. Thus, it is difficult to pack the cone 12 when it is full or has a certain amount of ground organic material that has not been packed yet. When the cone 12 is not packed frequently, attempts at packing the cone 12 to the desired amount of compactness often result in damage to the cone 12. Thus, the ability to frequently pack the cone 12 by quickly removing the grinder assembly 22, packing, and quickly reattaching the grinder assembly 22 to continue grinding enables efficient and easy loading of the cone 12 with more compact ground organic material.
When the cone 12 is filled, the cone holder 24 may be removed from the cylindrical body 20, and the packer rod 28 may be inserted into the aperture 84 of the cone holder 24 at the bottom end of the cone holder 24. The packer rod 28 may be used to push the loaded cone 12 out of the cone holder 24.
The flow chart of
Referring to step 101, engagement threads are formed spaced circumferentially on an upper end of a main cylindrical body via CNC milling. The engagement threads may be formed on an outer surface of the cylindrical body. The engagement threads may comprise a number of sets of engagement threads evenly spaced circumferentially on the upper end. In some embodiments, three sets of engagement threads are formed. Each set of engagement threads may comprise three threads protruding from the upper end of the cylindrical body and circumferentially extend in parallel on the upper end of the cylindrical body. In some embodiments, the cylindrical body and therefore the engagement threads may be made of aluminum, aluminum alloy, or the like. By forming via CNC milling, the dimensions of the engagement threads are consistent and uniform, thereby preventing jams when attaching and removing components. This step may also include forming engagement threads circumferentially spaced on a lower end of the cylindrical body via CNC milling. In some embodiments, the cylindrical body itself is formed via CNC milling.
Referring to step 102, engagement threads are formed circumferentially spaced on a lower end of a grinder assembly via CNC milling. The engagement threads may be formed on an inner surface of the lower end. The engagement threads may also comprise a number of sets of engagement threads evenly spaced circumferentially on a lower end of a grinder cylindrical body that is operable to mate with the upper end of the cylindrical body. The engagement threads are complementary to and operable to engage the engagement threads on the upper end of the cylindrical body. In some embodiments, three sets of engagement threads are formed. Each set of engagement threads may comprise three threads protruding from the lower end of the grinder cylindrical body and circumferentially extending in parallel on the lower end of the grinder cylindrical body. In some embodiments, the grinder cylindrical body and therefore the engagement threads formed thereon may be made of aluminum, aluminum alloy, or the like. Portions of the grinder assembly may be formed via CNC milling. By forming via CNC milling, the dimensions of the engagement threads are consistent and uniform, thereby preventing jams when attaching and removing the grinder assembly from the main cylindrical body. In some embodiments, the blades of the grinder assembly are made of FDA grade titanium, titanium alloy, or the like.
Referring to step 103, a cone holder is inserted into a bottom opening of the cylindrical body. This step may include forming engagement threads circumferentially spaced on a lower end of the cone holder via CNC milling. The cone holder may also be made of aluminum, aluminum alloy, or the like and formed via CNC milling. By forming via CNC milling, the dimensions of the engagement threads are consistent and uniform, thereby preventing jams when attaching and removing the cone holder from the main cylindrical body. This step may also include orienting the threads of the cylindrical body so that they pass through spaces defined by the circumferentially spaced threads of the cone holder. Once the cone holder is inserted into the cylindrical body, this step may include rotating the cone holder and the cylindrical body relative to one another so that the engagement threads of the cylindrical body engage the engagement threads of the cone holder, thereby releasably securing the cone holder to the cylindrical body.
Referring to step 104, a funnel is inserted into a top opening of the main cylindrical body so that a narrow portion of the funnel extends into an end opening of a cone when the cone is held by the cone holder within the cylindrical body. The funnel may be inserted into the top opening of the cylindrical body so that a portion of the funnel abuts the upper end of the cylindrical body. Particularly, the funnel may include a flange that abuts the upper end of the cylindrical body. The funnel may also be made of aluminum, aluminum alloy, or the like and formed via CNC milling. The funnel and cylindrical body may be tightly mated so that the funnel is semi-permanently secured to the cylindrical body, e.g., it would require significant force and/or lubricants to push the funnel out of the cylindrical body.
Referring to step 105, the upper end of the cylindrical body is inserted into the lower end of the grinder assembly. This step may include inserting the cylindrical body into the bottom opening of the lower end of the grinder cylindrical body until a collar of the cylindrical body abuts the lower end of the grinder assembly. This step may also include orienting the threads of the cylindrical body so that they pass through spaces defined by the circumferentially spaced threads of the grinder assembly. This step may include inserting the cylindrical body into the lower end of the grinder assembly with the funnel already inserted into the cylindrical body so that the funnel is sandwiched by the grinder assembly and the cylindrical body. In some embodiments, a lower blade of the grinder assembly abuts the flange of the funnel.
Referring to step 106, the cylindrical body is rotated relative to the grinder assembly so that the engagement threads of the grinder assembly engage engagement threads of the cylindrical body, thereby releasably securing the grinder assembly to the cylindrical body.
