A package having a lid seated on a base where the edge of the seated lid is generally inaccessible, and where the edge is made accessible by a movement of a tamper-evident tab. The base and lid are configured so that opening of the tamper-evident tab locks the tab in the opened position. The inner edge of the tamper-evident tab is joined to the base by a hinge. The tamper-evident tab includes a protrusion that extends inwardly beyond the hinge. The lid includes a retention feature overlying the tamper-evident tab. The protrusion interacts with the retention feature to provide an audible indication when the tamper-evident tab is opened and to retain the tamper-evident tab in the opened position. The protrusion may be configured to lift the lid when the tamper-evident tab is in the opened position.

Closure for a container mouth, the closure comprising: a cover portion (18) for covering at least a portion of the container mouth; a fastener portion (20) for engaging the container for fastening the closure to the container; and a peelable bracing portion (22) extending generally in a circumferential direction of or around an axis of the closure, the bracing portion overlapping at least partly the cover portion and the fastener portion, and configured to reinforce the closure by bearing, as shear stress at an interface between the bracing portion and at least one of the cover portion and fastener portion, support force in or between one or both of the cover portion and the fastener portion.

A lid structure for a container has an annular collar for attachment to the container. The collar has an opening for providing access to an interior of the container. The lid structure further includes a lid for closing the opening. The lid has an outer periphery and an upper surface with a circumferential ridge located near to but spaced from the outer periphery, whereby a further container having a base diameter can stack at an outside of the circumferential ridge. The circumferential ridge has at least two interruptions dividing the circumferential ridge into at least two ridge portions whereby at least two further containers having the same base diameter can stack partially on the lid.
