Patent US10583949
Issued 2020-03-10
Machine For Filling Oil Cartridges
A machine for filling cannabis oil or other fluids into dispensing cartridges includes a fluid reservoir, a fluid pump, and an injection needle. The fluid pump may be disposed directly below the fluid reservoir, and the injection needle may be disposed directly below the fluid pump. A lift mechanism raises and lowers a movable cartridge holder to move a dispensing cartridge toward and away from the injection needle. A heater may be formed about the needle to heat fluid therein. Heaters may also be provided for heating the fluid reservoir and the fluid pump.

- 1. An apparatus for injecting a fluid into a dispensing cartridge, comprising in combination:
a needle having a shaft extending between a first end adapted to receive fluid and an opposing second end adapted to dispense fluid; a reservoir adapted to store a fluid; a fluid pump having an inlet coupled to the reservoir and adapted to receive fluid therefrom, the fluid pump having an outlet adapted to selectively force fluid therefrom, the outlet being coupled to the first end of the needle; a cartridge holder adapted to releasably hold a dispensing cartridge to be filled; and a needle heater disposed proximate the shaft of the needle and adapted to heat fluid therein for preventing such fluid from coagulating within the needle, wherein the needle heater includes a generally cylindrical bobbin extending around the shaft of the needle, and resistive wire coiled about the bobbin, the resistive wire being adapted to generate heat when an electrical current is conducted thereby.
- 10. An apparatus for injecting cannabis oil into a dispensing cartridge, comprising in combination:
a reservoir adapted to store cannabis oil, the reservoir including an outlet for delivering stored cannabis oil; a fluid pump having an inlet coupled to the outlet of the reservoir for receiving cannabis oil therefrom, the fluid pump having an outlet adapted to selectively force cannabis oil therefrom; a needle having a shaft extending between an inlet end adapted to receive cannabis oil and an opposing outlet end adapted to dispense cannabis oil, the needle being disposed generally directly below the fluid pump, and the inlet end of the needle being connected directly to the outlet of the fluid pump by a valveless connection for receiving cannabis oil directly therefrom; and a cartridge holder adapted to releasably hold a dispensing cartridge to be filled with cannabis oil.
