Abstract
A tamper evident push-on type integral synthetic plastic closure cap for an externally beaded container neck, the body of the cap being formed with a thin central disk region, a thicker surrounding rim region, an interior ridged inner skirt provided with an interior sloping wall portion descending from the inner edge of the rim region, and an outer skirt descending from the outer edge of the rim region, the outer skirt being provided with an arcuate, buttressed lifting tab extending horizontally from a portion of the outer skirt, two inward projecting ribs on the internal side of the skirt, a circumferential weakened region in the skirt disposed between the ribs separating the skirt into distinct upper and lower regions and a descending tear tab projecting downwardly from the lower edge of the lower region of said skirt so that lifting of the tab will break the wall of the skirt and separate the skirt at the weakened region to detach the lower skirt and rib from the remainder of the cap by tearing along the circumferential weakened region.
