A mixing-dosage apparatus for rotary machines for packaging containers includes a mixing portion and a dosage portion. The two portions have a selective fluid connection using a flow control valve, which acts between the two portions so as to feed the dosage duct with consecutive loads of mixed food mass. Each load has a volume that is approximately equal to the volume of the mixing chamber.

An apparatus for the automated filling of cartridges of e-vapor devices may include a filling drum configured to receive at least one cartridge of an e-vapor device. The apparatus may additionally include a needle assembly including at least one hypodermic needle. The needle assembly is configured to transition between a lowered state and a raised state. The lowered state is where the hypodermic needle is moved down into the cartridge, while the raised state is where the hypodermic needle is lifted up and away from the cartridge. The apparatus may further include a pump assembly configured to pump a pre-vapor formulation into the cartridge when the needle assembly is in the lowered state. The pump assembly may include a variable amplitude cam system configured to adjust an amount of the pre-vapor formulation for pumping to the cartridge without changing start and stop times for the pumping.

Some embodiments relate to a metering device, including: a metering chamber; a piston separating the metering chamber into a supply compartment and a metering compartment, the piston including a passage between the two compartments; a valve for closing the passage, allowing the passage of the product when same is in the open position; and movement mechanisms of the valve. The valve includes drive mechanisms of the piston arranged on either side of the piston in such a way that the movement of the valve in a discharge direction drives the movement of the piston in the discharge direction and the movement of the valve along the length of the cylinder body in a transfer direction, and drives the movement of the piston.
