Abstract
Moulding equipment in which cooperable male and female connectors of a mould and a dispensing container for mouldable material have means to lock them together. This includes a locking member which is manually moveable in pivotal fashion upon one connector into and out of a locking position with the other connector. Opposing surfaces of the locking member and the other connector relatively move across each other during movement of the locking member while offering sufficiently low resistance to movement to allow for manual operation. During transfer of the material into the mould, the opposing surfaces are urged together by moulding pressure to increase resistance to movement of the locking member out of the locking position. In preferred constructions, the locking member has a cam surface which ensures the need for a progressively increasing unlocking force to enable release of the locking member during transfer of the mouldable material.
