Abstract: In one example, a lid configured for use with a container includes an upper surface that is generally circular in shape, and further includes a side wall with an annular configuration, the side wall intersecting the upper surface to define an edge of the lid. A grip element is defined in the upper surface and sized and configured to be grasped by one or more fingers of a user, and the grip element includes a grip portion that is set back a distance from the edge of the lid. Finally, a tab is provided that is attached to the side wall of the lid by an elastically deformable standoff element.

Abstract: In one example, a cap includes a body that has a plug defined by a recess extending downward from an upper surface of the body. The body also includes a skirt disposed circumferentially about the plug such that a gap is defined between an exterior surface of the plug and an inner surface of the skirt. Two or more tongues are connected to the skirt and extend radially inward toward the plug, each of the tongues configured to releasably engage respective corresponding structure of a container. A seal is provided that is disposed about an outer surface of the plug so as to be concentric with the plug, the seal including multiple radially extending circumferential fins.
