Connecting a plastic fitting to a glass container

摘要

A system to hold a plastic fitting (2) at a glass vessel (3) e.g. a coffee jug, has a twin-wall structure at the fitting as an inner (11) and outer (12) wall around the glass vessel wall (20) at the vessel opening section (8), which has a narrowed neck (6). A system to hold a plastic fitting (2) at a glass vessel (3) e.g. a coffee jug, has a twin-wall structure at the fitting as an inner (11) and outer (12) wall around the glass vessel wall (20) at the vessel opening section (8), which has a narrowed neck (6). An unbroken ring (19) is around the glass neck, to support the plastics fitting in a positive fit, locked together by complementary recesses (22) and projections (17,26) at the ring and at the inner surface of the plastics outer wall. The gap between the plastics fitting and the glass wall is filled by an adhesive.
