An apparatus for making, well and sealing of a casing made of thermoplastic plastic

摘要

The apparatus has a container-shaping device (12, 12a, 16, 16a) and a filling device (6). The container-shaping device has two bottom-mould halves (12, 12a), movable relative to one another and provided with holding members for holding a tubular plastic blank, for the shaping of the container belly and the container bottom and upper-mould halves (16, 16a), arranged above them and movable independently of the bottom-mould halves, for the shaping of the container head. The filling device is provided with a gas pipe, a filling pipe and a vent pipe. So that powdery or granular materials can be dispensed (for filling) in predetermined quantities by means of such an apparatus, the filling pipe (34) accommodates a dust-retaining and gas-permeable device (38) which limits the quantity receivable by the filling pipe. Moreover, the filling pipe can be connected selectively to an underpressure source or to an overpressure source and can selectively be connected to or separated from a supply container for powdery material.
