Cap with reduced thickness

A cap for a container, comprising:

• a body configured to be coupled and uncoupled relative to a neck of the container and including:
• a side wall internally threaded and extending around a longitudinal axis between a first and a second end, and
• a transverse wall joined to the first end of the side wall;
• a tamper evident ring configured to remain anchored to the neck of the container even when the cap body is uncoupled from the neck, the tamper evident ring including:
• a retaining elemental configured to engage a locking member on the neck of the container, and
• a joining portion where the tamper evident ring is joined to the cap body, the joining portion being configured to be torn along a perimeter surrounding the longitudinal axis in response to a movement of the body away from the tamper evident ring;
• and
• a connecting window formed of a portion of the side wall of the cap body, a corresponding portion of the retaining element, and a stretch of the joining portion interposed between them, wherein the connecting window has a first dimension along the direction of the longitudinal axis, and a second dimension along a perimeter surrounding the longitudinal axis, and wherein the connecting window includes:
• a connecting band which is greater in length than the first dimension of the connecting window, the connecting band having a first end connected to the side wall of the cap body, a second end connected to the retaining portion of the tamper evident ring, a first flank, and a second flank opposite to the first flank, each of the first flank and the second flank extending from the first end to the second end of the connecting band;
• and
• a film having a reduced thickness compared to the connecting band and being adjacent to the first flank and the second flank of the connecting band along the whole length of the first flank and the second flank of the connecting band from the first end to the second end, to join the first flank and the second flank of the connecting band to respective portions of the cap body side wall and of the retaining element which surround the connecting window,
• wherein the cap is adapted to be positioned in:
• a first working configuration, where the retaining portion of the tamper evident ring engages the locking member of the container neck, so that the cap body is coupled to the container neck and the joining portion of the tamper evident ring and the film of the connecting window are intact, and
• a second working configuration, where the retaining portion of the tamper evident ring engages the locking member of the container neck, so that the cap body is uncoupled from the container neck, the joining portion of the tamper evident ring and the film of the connecting window are torn, and the tamper evident ring is joined to the cap body by the connecting band.
