Abstract
A closure is provided for a container and includes a base and a lid. The base includes a body for mounting to the container, and the body defines a dispensing orifice. A tamper-evident seal extends across the dispensing orifice. The lid includes a peripheral frame, a flexible panel, and a penetrator member extending from the panel for penetrating the seal.
Claims23
A closure for an opening to a container interior, said closure comprising:
- a base;
- said base including a body that is molded from at least a first material and that is adapted for mounting to said container around said opening, said base body defining a dispensing orifice for communicating with said container opening;
- said base first material also defining at least a portion of a tamper evident seal unitary with said base body and extending across said dispensing orifice;
- and
- a lid adapted to be mounted on said base to cooperate with said base for occluding said dispensing orifice in a closed position over said base body and for being moved away from said closed position to permit the dispensing of container-stored contents out of said orifice, said lid including (a) a peripheral frame, (b) a flexible panel that is connected with said frame and that is normally biased to an outwardly convex configuration as viewed from outside said lid, (c) only one reduced thickness, film hinge joining the periphery of said flexible panel to said lid peripheral frame for accommodating flexure of said flexible panel to a self-maintained inverted inwardly concave configuration, and (d) a penetrator member extending from said flexible panel for penetrating said seal when said flexible panel is in said inwardly concave configuration.

A closure for an opening to a container interior, said closure comprising:
- a base that is coinjection molded from first and second materials for mounting to said container around said opening, said base having an exterior and an interior, said first material defining said exterior, and said second material being encapsulated by said first material, said base defining a dispensing orifice for communicating with said container opening, said base including a tamper evident seal unitary with said first and second materials and extending across said dispensing orifice;
- and
- a lid adapted to be mounted on said base to cooperate with said base for occluding said dispensing orifice in a closed position over said base body and for being moved away from said closed position to permit the dispensing of container-stored contents out of said dispensing orifice, said lid including (a) a peripheral frame, (b) a flexible panel that is connected to said frame and that is normally biased to an outwardly convex configuration as viewed from outside said lid, (c) at least one hinge connecting said flexible panel to said frame for accommodating flexure of said flexible panel to an inverted inwardly concave configuration, and (d) a penetrator spike extending from said flexible panel for penetrating said seal when said flexible panel is in said inwardly concave configuration.
