Method of Making A Bayonet Sealing Closure For Containers and Lids

摘要

A method for forming a container assembly having a lid, a container and a cooperative closure mechanism, includes providing a lid form and flexible members biased toward the lid form, wherein the lid form and the flexible members are operable between a forming position defined by the lid form exerting a biasing force against the flexible members, and an extraction position defined by the biasing force being substantially removed from the flexible members, creating a lid form cavity defined by the lid form and the flexible members disposed in the forming position, injecting a lid material throughout the lid form cavity to form a lid, disposing the lid form and the flexible members in the extraction position, wherein the lid form is moved distal from the lid and the flexible members are biased away from the lid to separate the lid from the flexible members.

主权项

1. A method for forming a container assembly having a lid, a container and a cooperative closure mechanism defined by the lid and the container, the method comprising:
providing a first lid form having an outer wall and at least one channel; providing a flexible member disposed in each of the at least one channel, wherein the flexible member is biased toward the outer wall; creating a lid form cavity at least partially defined by an outward surface of the flexible member; injecting at least one lid material substantially throughout the lid form cavity to form a lid; retracting the first lid form from a forming position relative to the flexible member and the lid to an extraction position, wherein the flexible member is biased inward as the first lid form is retracted to separate the outward surface of the flexible member from a side wall of the lid; and separating the lid from the flexible member.
