Abstract: A cap for sealing a mouth of a crown finish or threaded crown finish glass bottle, the crown cap is formed by a circular wall, a curved wall perimetrical to the circular wall, and a closure skirt that descends radially downward and outward from the curved wall and formed by a plurality of interleaved protrusions and depressions, the curved wall has a radius of curvature from 1.5 mm (0.590551 in) to 1.9 mm (0.748031 in) and an arc less than 86°; the crown cap is formed from a circular sheet cutout with a diameter from 33.4949 mm (1.3187 in) to 35.5346 mm (1.399 in), resulting in a crown cap with an axial height less than the axial height of a crown cap from the state of the art.

Abstract: Disclosed is a metallic cover cap for sealing a metallic bottle, comprising a gasket provided with a flat central zone and an annular zone which includes an outer rim and an inner rim that are separated by a notch, such that the outer rim extends axially, continues circumferentially, and includes: a first surface; a second surface with a flat portion and a concave portion radially opposite the notch; and a third flat surface that extends between the first and second surfaces, and the inner rim extends axially, continues circumferentially and spaced radially inwards of the first rim, and includes: a first flat surface opposite and perpendicular to the flat zone; a second concave surface radially opposite the notch; and a third flat surface between the first and second surfaces that is inclined toward the notch.

Abstract: A crown-type metal cap for sealing the mouth of a preferably aluminum metal bottle, the cap being formed by a laminar part of circular plan form, including an inner face and an outer face and provided peripherally with a closure skirt and, on the inner face, with a closure gasket including a peripheral lip. The cross-section of the peripheral lip is formed by a convex arc having at least one radius of curvature, adjacent to the closure skirt, the lip also including a side opposite the closing skirt, which can be a straight side or a curved side having a radius of curvature greater than that of the convex arc.

Abstract: A closure cap adapted to be removably retained on a container can include a cap portion and a film portion. The cap portion can include an opening adapted to permit flow from an interior of the container to an exterior of the container when the closure cap is retained on the container. The film portion can be adapted to prohibit flow through the opening and can be positionable to permit flow through at least a portion of the opening when the closure cap is retained on the container. A drinking straw can be introduced into the opening to permit flow from the interior to the exterior of the closure cap.
