Cap with a cutting element

A cap configured to be mounted on a neck of a container provided with an exterior thread, the cap comprising:

• a top portion;
• a sidewall portion projecting axially from the top portion and formed in one piece with the top portion to surround an interior of the cap, the sidewall portion comprising an interior thread configured to threadably engage the exterior thread of the neck during an opening operation and during a closing operation;
• a tamper evidence removably attached to the sidewall portion;
• the sidewall portion further comprising a plurality of cutting elements each possessing a first end hingedly attached to the sidewall portion so that each cutting element projects inwardly toward the interior of the cap and is pivotable in an axial direction, each cutting element also possessing a free end portion configured to interact with a membrane portion of the neck to separate the membrane portion from a spout portion of the neck;
• and
• wherein the cutting elements each comprise a local protrusion extending from an axial side of the cutting element.

• at least one stop element formed in one piece with the sidewall portion, the stop element extending axially along an upper part of the sidewall portion and projecting inwardly from the sidewall portion to contact a counter element of the neck to limit axial movement of the cap and prevent damage to the membrane portion;
• and
• the at least one stop element terminating at an end that is spaced from the interior thread so that the interior thread is positioned axially between the end of the at least one stop element and the tamper evidence.
