A resealable membrane lid for a container comprising:
- a peelable portion, the peelable portion comprising:
- a peelable upper layer having an upper surface and a lower surface,
- a peelable lower layer having an upper surface and a lower surface, and
- a pressure sensitive adhesive layer adjacent at least a portion of the lower surface of the peelable upper layer and at least a portion of the upper surface of the peelable lower layer,
- wherein the peelable portion further comprises a central portion and a first pull tab which extends radially from the central portion, and
- wherein the peelable portion comprises a plurality of score lines which extend at least substantially through the peelable lower layer but do not extend into the peelable upper layer, the score lines comprising:
- a first score line which is disposed interior of a perimeter of the central portion of the peelable portion, is at least partially circumferential, and defines a peripheral region between the first score line and an edge of the peelable portion,
- at least one second score line disposed along the perimeter of the central portion of the peelable portion, adjacent the first pull tab, and
- a third score line which forms the perimeter of a second pull tab;
- a removable portion, the removable portion comprising:
- a removable upper layer having an upper surface and a lower surface and
- a removable lower layer having an upper surface and a lower surface and having a fourth score line disposed circumferentially therethrough,
- wherein the upper surface of the removable lower layer is affixed to the lower surface of the removable upper layer and the lower surface of the removable lower layer is configured to be sealed to the rim of a container, and
- a permanent adhesive layer disposed:
- within the peripheral region, adjacent the removable upper layer and the peelable lower layer, and
- within at least a portion of the perimeter of the second pull tab, adjacent the removable upper layer and the peelable lower layer.
