Abstract of the Disclosure A sheet metal can end or cover comprises a largely or wholly removable panel bounded by a peripheral tear line, and an integral closure within the panel, the closure being defined by a generally arcuate groove or depression formed at one side therof with a coterminous, rupturable weakening line having a mid-locality extending nearer to but spaced from the panel tear line to provide a lifting lip therefor and a defiectable tongue portion extending toward the center of the panel. The weakening line and the tear line are preferably of the fractured but intergral type fully disclosed in our U.S. Patent 3,681,630 and extend on opposite sides of the panel. On depressing the locality of the mentioned weakening line with a tool, such as the tip of a spoon, the closure opens then permitting the tip to bear upwardly on the inside of the lifting lip as the bowl of the spoon is pivoted upon the tongue portion. Consequently the panel tear line is progressively ruptured and the panel may be readily tilted upwardsly or fully removed by bearing downwardlyon the tool handle.
