Description

1 APPARATUS FOR TRANSFERRING HERB MATERIAL FROM A GRINDER This invention relates to an apparatus for transferring herb material such as cannabis or tobacco from a grinding device to an end use location such as a paper rolling machine, a pipe or other smoking appliance. BACKGROUND 5 OF THE INVENTION Herb grinders are widely available for grinding plant material such as cannabis and tobacco and have become more widely used in the legalization of cannabis products which has occurred in many countries and states. The grinder incudes a rotating component which directs the material through a screen to collect 10 the more desirable components such as the keif particles from the resin glands of the plant. These contain a majority of the active ingredients and are preferably separated for most effective use. The grinder typically includes a filter which separates the main body of the plant material from a chamber into which the collected material falls. 15 One problem that arises when using a herb grinder, is that there is no device available that can clean the screen that sifts the finer Keif particles to the bottom chamber. The second issue noticed is that there is no device that can transfer the organic matter without the use of the user’s fingers. This contaminates the organic matter with contaminants from hands. It will also contaminate the hands with organic 20 matter. It is one object of the present invention to provide a Multi tool designed for use with tobacco and cannabis which assists with scraping the material through CA 3184099 Date reçue / Received date 2026-02-06 2 the filter screen and with collecting the material from the chamber for transfer to the end use location.

DETAILED DESCRIPTION The apparatus shown in Figures 9 to 11 is designed for use in 15 transferring cannabis from a grinding device to an end use location. The apparatus is formed by a sheet material 10 formed around a hollow interior 11 to define a generally tubular body 12 which has a base wall 13 and two side walls 14 and 15 standing upwardly from the base wall 13. The sheet material can be formed by many suitable processes including 20 injection molding or thermal forming so that it is not intended that the sheet material necessarily be supplied in flat form and wrapped, but instead any forming technique CA 3184099 Date reçue / Received date 2026-02-06 8 can be used which ends up defining a body with a continuous wall of a generally constant thickness defining the base and side walls as described hereinafter. The two side walls 14 and 15 converge upwardly and inwardly to respective top edges 16 and 17 thereof spaced from the base wall 13 to define an open slot 18 between the side 5 edges 16 and 17. The generally tubular body 12 defines a first scraper end 19 and a second pinching end 20. Both ends are open at both the first scraper end and at the second pinching end to allow the entry of the material to be transferred. The base wall at the scraper end forms a generally flat scraper edge 21 10 across the base wall 13 projecting forwardly at the scraper end so that the tubular body can be grasped manually to operate the scraper edge in a scraping action over a filter surface of the grinding device. The tubular body is narrower at the second end as shown in Figure 10 so that the base wall 13 converges gradually so that material scraped into the tubular 15 body at the scraper end is converged by the side walls in the form of a funnel. The side walls 14 and 15 at or adjacent the scraper end extend upwardly from the scraper edge 21 at the base wall to an upper edge 22, 23 thereof which is inclined upwardly and rearwardly from the scraper edge at the base wall. Thus a point 22A, 23A on the upper edges is recessed away from the scraper edge to form an open 20 shovel area 24 above the base wall and between the recessed side walls. CA 3184099 Date reçue / Received date 2026-02-06 9 The side walls 14, 15 at the position 22A, 23A remote from the scraper end each include a second converging wall portion 26, 27 which is inclined upwardly and inwardly toward the slot 18. The converging walls 26, 27 lie at an angle to the lower sections of the side walls 14, 15 so as to converge more sharply. The lower portions may be at right angles to the base or may slightly diverge. 5 The converging wall portions 26, 27 each have a leading edge 28, 29 inclined upwardly and rearwardly of the scraper edge. And converging in a V-shape to the slot 18 at an apex 18A. In this way the upper portions are further recessed away from the edge 21 to further define the shovel area 24. 10 The leading edges 28, 29 of the converging wall portions 26, 27 are inclined upwardly and rearwardly of the scraper edge toward the slot 18 where the slot has a forward most portion 18A spaced rearwardly of the scraper edge 21 to define the open shovel portion 24 above the base wall 13. The side walls 14, 15 at or adjacent the second pinching end 20 include 15 the converging portions 26, 27 extending upwardly and inwardly above the base wall 13 so as lie closely adjacent at the second end 20 to form the slot 18. The side walls 14, 15 and converging portions 26, 27 extending therefrom are sufficiently flexible to allow the side walls to be squeezed to pinch the material on the base wall by closing the slot 18 or even overlapping the side edges defining the slot. 20 The tubular body being formed of a sems-rigid flexible material so that the side walls can be squeezed together at the open slot in a pinching action so as to pinch the material within the hollow interior between the side walls for manual transfer. CA 3184099 Date reçue / Received date 2026-02-06 10 The sheet material can be made from a flexible plastics material which retains its shape except when squeezed and for this purpose a PVC is suitable which can be typically 0.76mm thick PVC The tool thus constructed can be used where the shovel or wider scraper end 21 is used to scrape the screen of the grinder, which helps the finer 5 Keif particles drop through the screen. The Shovel End, after scraping is complete, can be used to scoop in the organic matter into the hollow interior. The body is held manually and operated to move the scraper end as a pick up surface to slide the material from the container over the scraper edge 21 into the hollow interior 11 from which it can be 10 transferred back out through the scraper end 19 by sliding from the hollow interior into an end use location. The tubular body can also be reversed in the hand so that the pinching end 20 can be used to scoop in organic materials. This is then held in place by squeezing the side walls together with the thumb and index finger to pinch the sides of the device. This holds the organic matter in the device until transferred to an end 15 use location. The user then lets go of the side walls to release the pinching or squeezing action and the organic matter drops out of the device into the container. The user can also scoop the organic matter into the scraper end and discard the material collected through the second end 20 by sliding through the hollow interior while being converged by the side walls in the form of a funnel. 20 CA 3184099 Date reçue / Received date 2026-02-06
