Abstract:
1. A method for manufacturing a sealable container closure, comprising: providing a first mold section, a second mold section and a third mold section; mating the first mold section with the second mold section to form a first cavity area; injecting a fusible polymeric material into the first cavity area to form a fusible ring having a shelf and at least one passage between an inner periphery and an outer periphery of the fusible ring; removing the second mold section from the first mold section after the fusible polymeric material has been injected into the first cavity area to form the fusible ring; subsequently placing a panel on the shelf of the fusible ring; subsequently mating the third mold section with the first mold section to form a second cavity area within which the fusible ring is located; and subsequently injecting a thermoplastic polymeric material into the second cavity area to form a frame, wherein a first segment of the frame is within the inner periphery of the fusible ring, a second segment of the frame is outside the outer periphery of the fusible ring, and a third segment of the frame extends through the passage of the fusible ring between the first and second segments of the frame and wherein the panel, frame and fusible ring form the closure.
