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.
Claims16
A crown cap configured to seal a mouth of a crown finish or threaded crown finish glass bottle, the crown cap comprising a laminar plate with an inner face and an outer face, 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 projections and depressions;
- wherein in a pre-closure condition of the crown cap 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°.
A crown cap configured to close and seal a mouth of a crown finish or threaded crown finish bottle, the closed crown cap comprising a laminar piece formed by a circular wall, a curved wall perimetrical to the circular wall, and a closure skirt marginally folded on the mouth of the glass bottle and descending radially downward from the curved wall, wherein in a pre-closure condition of the crown cap the curved wall has an arc less than 86°, wherein the closure skirt includes minor projections and interleaved gripping depressions, wherein each minor projection includes a central depression between a pair of opposite second convex flanks and each gripping depression includes a securing groove and a contact wall.
A crown cap configured to seal a mouth of a crown finish or threaded crown finish glass bottle, the crown cap comprising a laminar plate with an inner face and an outer face, 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 projections and depressions;
- wherein 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°,
- wherein the crown cap is configured to transition between a pre-closure state and a closure state, wherein in the closure state, an axial height of the crown cap is between 5.3 mm (0.208661 in) to 5.8 mm (0.228346 in).
