Tamper evident closure

A closure for a bottle, comprising:

• an inner shell having an inner cover and an inner skirt depending from the inner cover in a first vertical direction, and an outer shell;
• wherein the inner shell includes at least one inner lug disposed on the inner cover and extending away from the inner cover in a second vertical direction opposite the first vertical directions;
• wherein the outer shell includes at least one outer lug;
• wherein the at least one outer lug is axially movable relative to the at least one inner lug between an engaged position and a disengaged position;
• wherein in the disengaged position the at least one outer lug is axially displaced relative to the at least one inner lug such that the at least one outer lug is able to rotate past the at least one inner lug when rotated in an opening direction;
• wherein in the engaged position the at least one outer lug is at least partially circumferentially aligned with the at least one inner lug such that the at least one outer lug engages the at least one inner lug when rotated in an opening direction to cause opening direction rotation of the inner shell;
• and
• a tamper band extending downwardly in the first vertical direction from the inner skirt;
• wherein the tamper band includes a portion that extends radially inwardly to engage a bead of the bottle;
• wherein the at least one inner lug includes an inner edge and an outer edge, wherein the at least one inner lug outer edge extends upwardly in the second vertical direction to a greater height relative to the inner skirt than the at least one inner lug inner edge to accommodate for doming of the inner shell.

A package, comprising:

• a container configured to store pressurized contents, the container having a product storage region and a neck defining an opening;
• and
• a closure having an inner shell and an outer shell;
• wherein the inner shell includes an inner cover and inner skirt depending downwardly from the inner cover in a first axial direction;
• wherein the inner cover includes at least one inner lug extending away from the inner cover in a second axial direction opposite the first axial direction;
• wherein the outer shell includes a lid having at least one outer lug;
• wherein the at least one outer lug is movable relative to the at least one inner lug in the first axial direction and the second axial direction between an engaged position and a disengaged position;
• wherein in the disengaged position the at least one outer lug is able to rotate past the at least one inner lug when rotated in an opening direction;
• wherein in the engaged position the at least one outer lug engages the at least one inner lug when rotated in an opening direction to cause opening direction rotation of the inner shell;
• wherein the at least one inner lug includes an inner edge and an outer edge and wherein the at least one inner lug extends radially outwardly from the inner edge to the outer edge;
• wherein the inner cover extends from the inner skirt downwardly in the first axial direction as it extends toward a central axis at a first angle such that the at least one inner lug is disposed downwardly farther in the first axial direction proximate the inner edge than proximate the outer edge to accommodate expected doming of the inner shell caused by the pressurized contents stored in the container;
• and
• a tamper band extending downwardly from a skirt of the inner shell;
• wherein the tamper band includes a portion that extends radially inwardly to engage a bead of the container.
