Abstract

Closures for blow moulded containers are derived from the same parison and moulding cycle as the containers, either by blow moulding a section of parison above the container mouth, or by compression moulding surplus parison material nipped below the base of the moulding. Blow moulded closures are obtd. by inflation due to a pressurisation needle inserted in a parison zone between the levels of the tops of the containers and the base of the closure. The zone may be separated by cutting or tearing in situ or after ejection. Compression moulded closures are formed between mobile cavity blocks located in an ancillary chambers on the bases of the twin tools for the container mould. Pref. one of the blocks incorporates a spring-loaded insert for automatic ejection of the closure from the male tool as the moulds open. The mould blocks may be temp. controlled independently from the container cavity mould tools. Dial purpose moulding simplifies the prodn. and matching containers and their closures.
