IMPROVEMENTS IN MOULDED SYNTHETIC CLOSURE MANUFACTURE

摘要

A mould apparatus (1) for producing a moulded synthetic closure for a container, such as a synthetic cork for a wine bottle, the apparatus including one or more mould cavities (14), the capacity of which is infinitely variable during charging or filling of the or each cavity (14) by means of a piston (16) slidably engaged within the or each cavity (14), and wherein the distal end of the piston (16) constitutes a movable end wall of its associated mould cavity, and wherein each piston (16) acts as an ejector for removing the moulded product from the or each mould cavity (14). A method of manufacturing moulded synthetic closures using the mould apparatus (1) is also disclosed, as are moulded synthetic closures produced thereby.
