Abstract
A device for dosing a plastic, perishable mass into moulds has a pressing chamber for receiving a dose of the mass from a feed vessel and a piston operable in the chamber to push and compress the dose into a mould. The device includes a valve for shutting off feed of the mass from the feed vessel and is particularly constructed to avoid spaces into which the mass can collect and spoil, while preventing reentry of the mass from the pressing chamber into the feed vessel.
