A thread dosing feeder for extracting creams or gelatinous products contained within a tube from the tube whereby the dosing feeder tube can be applied to the tube, the thread dosing feeder comprises a rotary gate feeder (1), the rotary gate feeder (1) has a metering chamber, the metering chamber operates in conjunction with a plunger (3), the rotary gate feeder (1) is pivot-mounted on the thread dosing feeder and the thread dosing feeder has an outlet, and the thread dosing feeder has a re-circulation valve (11, 14, 20), the rotary gate feeder (1) has a concave finger receptor and is formed in one piece, whereby the metering chamber is locked and has an intake and discharge valve (6).

A metering device with a rotor inside a housing configured to isolate an upstream source, such as a reactor, form an output to atmosphere. The rotor rotates within the housing. The plate is placed within the housing between the rotor and the top of the housing and between the rotor and the bottom of the housing. The plate has a port through which steam passes to clear process fluid from the cylinder to the output. Steam regulates the temperature of the actuator and the components. Steam also activates the plate to improve the seal between the plate and the rotor.

Systems for measuring an ingredient are disclosed. A cap with a flexible silicone thread is configured to screw onto a threaded bottle and has a shaft and a slit. The cap has a rotatable filling section attached to the cap and configured to rotate to block the slit and prevent fluid communication between the threaded bottle and a dispensable volume or to expose the slit and allow fluid communication between the threaded bottle and the dispensable volume. A volume selector rotates to provide a largest and a smallest measurable volume. A lid covers the dispensable volume. A user rotates the rotatable filling section to fill the section with an ingredient. The user rotates it back, removes the lid, and dispenses the ingredient.
