Patent ID: 7083058

Claim:
A sealing closure for use with a container having a rim defining an opening, comprising: a top wall having a lower surface and an upper surface; an annular skirt extending downwardly from the top wall, including a container engaging means on an inner surface thereof adapted to releasably draw the sealing closure into engagement with the container; an annular flange extending downwardly from the lower surface of the top wall and radially outwardly toward the annular skirt, wherein the annular flange is resiliently flexible and upwardly deflectable and is adapted to engage an upper surface of the rim so as to provide an annular surface seal for the opening of the container; and at least one stop rib extending downwardly from the lower surface and extending radially inwardly from the annular skirt, the stop rib being adapted to contact the rim to limit a distance of upward deflection of the annular flange, the annular flange positioned so that it is located outside of the opening of the container, whereby the sealing closure can be installed on a container having a sealing membrane without damaging the sealing membrane.
