Definitions

  • the present invention relates to the grinding of vegetative material, e.g. cannabis, by means of a device configured such that a relatively precise predetermined dose or portion of the vegetative material results from the use of this device. Grinding is often also referred to as shredding of the vegetative material.
  • vegetative material such as cannabis, tobacco or herbs are often ground or shredded, easing the processing for consumption, and allowing for longer storage of the unground vegetative material while retaining its freshness as opposed to pre-ground material.
  • US8733679 discloses a device for shredding or grinding of herbs, tobacco and other vegetative material with a manually driven grinder assembly having two plates with opposing interdigitated teeth.
  • the device comprises a weighing mechanism relaying to the user a measured weight of the ground material that is collected in a weighing receptacle. Once the desired weight is achieved, the user is expected to stop the manual action of grinding the vegetative material in order to obtain the desired dose.
  • This known device has shortcomings which the present invention aims to overcome, the most important of which appears to be that the device disclosed in US8733679 tends to be inaccurate in the hands of the average user.
  • the present invention aims to provide measures that improve ease of use in producing a more correct dose of ground vegetative material by means of a device with a manually driven grinder. More specifically the invention aims to improve the reliability of delivering a repeatably consistent dose of the ground vegetative material.
  • the invention provides a device according to claim 1.
  • the device allows for the user to set the dose, e.g. based on a prescription, by operating the dose setting means before starting the manual grinding operation. Then the user can start the grinding operation, e.g. by rotating a grinder cap of the device relative to the base part. The ground material is shed from the grinding assembly and is collected and weighed. The weighing device is coupled to the locking mechanism.
  • the weighing, coupling, and locking is all embodied mechanically without the use of electronics.
  • the coupling causes the locking mechanism to lock the manually driven grinding assembly so that grinding is halted.
  • the manual grinder assembly can be operated again, e.g. in view of the next use of the device.
  • the inventive manual grinder device facilitates the user in obtaining an accurate dose, e.g. compared to the prior art approach wherein the user has to read the collected weight from a display and at the same time coordinate the manual grinding action. For many users this is too demanding, e.g. taking into account that use may be done when someone is tired, at night, in pain, etc.
  • the grinding assembly comprise two grinding parts, e.g. plates, with opposite grinding or working faces, each comprising a plurality of teeth.
  • the parts are arranged with their teeth facing each other and interdigitated yet free to move past one another when an allowable relative, preferably rotating, motion between the two parts is performed.
  • these teeth can be any type of sharp protrusions or relatively sharp protrusions cooperatively grinding or shredding vegetative material placed in between the grinding parts.
  • Relative motion between grinding parts can be achieved by one of the grinding parts, e.g. plates, preferably the upper grinding part, being attachable or attached to the main part, e.g. upper part, of the housing and the other grinding part being stationary relative to the base part of the housing, wherein the main part and base part of the housing are manually movable, preferably by a rotating motion, e.g. about a vertical axis, relatively to each other.
  • the base part is configured to be stationary during use, e.g. embodied to be placed on a table, and the main part is rotatable about a vertical axis relative to the base part, so that the user can grip the main part, e.g. while using one hand to stabilize the base part, and rotate the main part so as to drive the grinder assembly.
  • grinding can also be meant to convey comminuting, crushing, pulverizing, milling, granulating, mashing, smashing, grating, fragmenting, crunching, mincing, shredding, breaking up, macerating, reducing, chopping , chopping up, chopping into pieces, chopping finely, slicing, grinding down, ripping up, tearing up, cutting up, conjugations of these words or similar wording.
  • the relative motion between the grinding parts performs a grinding or shredding action on the vegetative material placed in between the grinding parts.
  • the grinding or shredding motion then produces ground or shred vegetative material small enough to be shed from the grinder assembly, e.g. to pass through openings in at least one of the grinding parts and/or past at least one of the grinding parts.
  • the grinding assembly comprises three or more grinding parts which when driven cooperatively grind the vegetative material placed in between the grinding assembly.
  • the weighing receptacle e.g. embodied as a cup, tray, basket or other container that is able to receive the ground material falling from the grinder assembly, e.g. through the openings or passing past a grinder part.
  • the weighing mechanism is housed in the housing, preferably in the base part thereof, such that the weighing receptacle can be placed at least in part within the housing, e.g. upon the weighing mechanism allowing the weighing mechanism to weigh (the contents of) the weighing receptacle.
  • the weighing receptacle is a removable receptacle.
  • the weighing receptacle is a removable receptacle which is configured to be removed after the predetermined dose of vegetative material has been ground, e.g. such that it can be emptied and contents used for further processing and/or consumption, after which it is to be placed back.
  • weighing mechanism collecting the ground material can also mean to catch, gather, receive, fall into, or otherwise gain possession over the vegetative material shed from the grinding assembly.
  • the weighing mechanism and the locking mechanism are coupled through a mechanical coupling mechanism that interacts with the dose-setting mechanism such that collection of the pre-set desired weight of vegetative material causes engagement of the locking mechanism through the mechanical coupling mechanism.
  • the device comprises purely mechanical parts as opposed to electronical parts, embodied as e.g. electric actuators, controllers, sensors.
  • the interacting dose-setting means and mechanical coupling mechanism comprises a bi-stable mechanism.
  • the bi-stable mechanism comprises a spring, wherein the spring force is adjustable and the dose setting mechanism is configured to set the spring force, e.g. by pretensioning the spring.
  • the bi-stable mechanism is spring loaded and the user must apply an intentional force, e.g. on the locking member, to switch the bi-stable mechanism back from enforcing the locked state into the unlocked state of the locking member.
  • locking of the manually driven grinding assembly can be achieved by means of an electronically activated locking mechanism.
  • weighing can be achieved by means of an electronical weighing apparatus which is electronically coupled to an electronically activated locking mechanism.
  • the coupling mechanism between the locking mechanism and the weighing mechanism can also be embodied as an electronical controlling device or mechanism or electronical controller.
  • the grinder assembly is configured to be driven by hand by rotating a grinder cap, e.g. interacting with an upper grinder member, relative to the base part of the device.
  • the device is dimensioned so that a user is able to place one hand on and/or around the main part, e.g. a grinder cap, and is able to stabilize, e.g. prevent motion of, the base part by the other hand, e.g. holding the base part stable on a table, such that the user is able to rotate the main part of the device relative to the base part by hand so that a grinding operation is performed.
  • a user is able to place one hand on and/or around the main part, e.g. a grinder cap, and is able to stabilize, e.g. prevent motion of, the base part by the other hand, e.g. holding the base part stable on a table, such that the user is able to rotate the main part of the device relative to the base part by hand so that a grinding operation is performed.
  • the device comprises a weighing pin supporting the receptacle and configured to move up and down relative to the base part, the up and down motion being based on the weight resting upon the weighing pin, e.g. the dose collected in the receptacle.
  • the up/down movement, e.g. the up/down stroke, of the weighing pin is configured to (also) be influenced by the pre-set setting of the coupled weighing and locking mechanism.
  • the weighing receptacle when in the active measurement state, rests upon the weighing pin such that the full weight of the weighing receptacle and its contents is measured by the weighing mechanism.
