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 metal cap comfortable for opening by turning or with a bottle opener. The crown metal cap before folding, has a bell-shaped closure flange with a plurality of intercalated protrusions and depressions, the protrusions have a smaller width than the width of the depressions, and each depression has on its outer edge a convex fold; such that when closing the closure flange is folded over the mouth of the bottle, each protrusion bifurcates into a pair of minor protrusions that acquire a curved shape separated by a central depression that takes a similar form within a spheroid, forming a flange surface comfortable to touch to facilitate manual opening by turning; whereas the convex fold of each depression prevents the collapse of the outer edge of the depression to form a bell-shaped opening edge for easy opening of the crown metal cap with the bottle opener.
