Abstract
A tamper-evident closure (40) is provided for a container. In one particular embodiment, the closure (40) has a body (42) and a hinged lid (44), and has the following additional features as next described. A tamper-indicating tab (120) is connected to the lid (44) by a frangible junction (130). A pressing member (150) is connected to the closure body (42) for movement from an initial unactuated configuration and to an inwardly deformed, actuated configuration. A post (170) is provided on either the pressing member (150) or tab (120), and a slot (140) is defined in the other of the pressing member (150) and tab (120), wherein the slot (140) non-releasably receives the post (170) when the lid (44) is first closed. The closure body (42) also has an inwardly located retention wall (160) defining an aperture (164). When the pressing member (150) is pressed inwardly, the frangible junction (130) is broken to allow the lid (44) to be lifted, and an end portion of the post (170) is non-releasably received in the retention wall aperture (164).
