摘要： Cutting device to form on a capsule for closing a container at least one connecting strap that keeps the capsule attached to the container after opening, the cutting, device comprising at least one cutting edge to make at least one cut on the capsule, the at least one cutting edge comprising a cutting start capsule inlet, a cutting end capsule outlet, and at least one transition cutting portion arranged on the capsule inlet and/or on the capsule outlet to form at least one cusp-shaped end zone, the at least one cutting portion being retracted with respect to a remaining part of the at least one cutting, edge so as to penetrate less the capsule of a remaining part of the at least one cutting edge reducing stress concentration and preventing initiation of a fracture in the at least one cusp-shaped end zone.

摘要： A closing cap for a container includes a separating line on a lateral wall forming a retaining ring, configured to remain anchored to a neck of the container and extending up to a free edge. A closing element is engageable with the neck, to open or close the container. The separating line is circumferentially interrupted to define in the lateral wall a joining zone, extending at a first angle, in which the retaining ring and the closing element are joined. An engagement element of the retaining ring is bent when the cap is closed. First and second incision lines allow deformability of a connecting portion and a region of the engagement element extending at a second angle, so that when first opening the closing element, the region goes beyond the locking ring and deforms to rest on the locking ring in an extended configuration.
