Patent ID: 8523009

Claim:
A closure for a container that comprises a base, a peripheral wall, and a rim, the rim forming an upper margin of the wall and surrounding an opening of the container, wherein a load bearing continuous wall formation is provided within the container adjacent to the rim, the closure comprising: an overlying portion configured to extend across and to overlie the opening of the container when the closure is mounted to the container; an inverted peripheral channel section having an inside wall, with the overlying portion being connected to the inside wall at a junction and extending inwardly from the inside wall of the inverted peripheral channel section, and the channel section being configured to mount on the container rim when the closure is mounted to the container; and a load bearing skirt including a single distal end and a single near end, the skirt continuously projecting to the distal end that is located remotely from the inside wall, the skirt continuously projecting from the near end located on an underside of the overlying portion at or adjacent to the junction of the overlying portion with the inside wall of the peripheral channel section such that, when the closure is mounted to the container, the distal end of the skirt is able to mount on the continuous wall formation to form a space between the rim and a remainder of the skirt, the space being above the distal end of the skirt that is mounted on the continuous wall formation, wherein the skirt contacts the continuous wall formation when the overlying portion is under load, so that a mass on the overlying portion is received by the skirt and transferred therefrom to the continuous wall formation to prevent inward collapse of the overlying portion under load.
