Document Type and Number:
Japanese Patent JPH05502651
Kind Code:
A
Abstract:
Closures for containers, such as cans and the like, wherein the closure is comprised of an end panel and a frame member which, preferably, are attached together during an insert-injection molding operation used for forming the frame member. Depending upon the respective materials, the attachment therebetween may comprise heat-bonding or adhesives and the like. The various end panels have a displaceable panel portion for providing an opening in the closure to provide access to the product(s) within the container. The various panel portions are defined by weakening lines, perforations or cut lines in the end panel and molded runners for "repairing" and/or sealing weakened or lanced portions of the end panels. The molded runners provide beam strength for protecting against excessive bulging during autoclave or other sterilization processes and against buckling during vacuum processing.
