<p>There is provided an interference-fit overcap (12) for a container (14) with a removable membrane (16). The overcap (12) includes a skirt (32) that provides an interference fit with the rim of the container surrounding an opening in the container when the membrane (16) is attached to the container (14). The overcap (12) also includes a circumferential ring (36) extending from the overcap (12) in a direction opposite the skirt (32). The circumferential ring (36) has an outside surface that is dimensioned to produce an interference fit with an inner wall of the container (14) after the membrane (16) has been removed. Thus the overcap (12) may be securely attached to the container (14) both before the membrane (16) is removed and after the membrane (16) is removed, such that the contents of the container (14) may be sealed by the overcap (12) after the membrane (16) is removed.
