Abstract
A closure is provided for a container. The closure has a body and a lid. The closure includes a tamper-indicating member connected to the body of the closure by an anchor member received in an anchor member-receiving aperture defined in the closure body. The tamper-indicating member is also connected along a frangible junction to the lid of the closure. A plug member extends from the tamper-indicating member and is receivable in a plug member-receiving aperture defined in the body. When the tamper-indicating member is depressed to force the plug member into the plug member-receiving aperture, the frangible junction is broken, and the tamper-indicating member is retained in its depressed position. This provides an indication that the closure may have been previously opened. Also, an overhanging portion of the lid can be readily engaged by a finger to facilitate opening of the lid relative to the body of the closure.
