1. A closure system comprising a container neck portion and a closure both with thread formations offering multiple angular distributed mutual engagement options to close the container neck portion, wherein the closure has a closure shell and a tamper-evident band connected through frangible connections that break when the closure shell and the container neck portion are fully unengaged for the first time forming an unattached tether, wherein characterized in that
being the tamper-evident band anchored at a lodging section of the container neck portion the tamper-evident band and the said lodging section are further configured to provide for a strong grip between them, so as to impede the free rotation of the tamper-evident band during the first and subsequent engagement operations of the closure shell and the container neck portion, and in that
the length of the tether is such that the closure system offers the user different re-closing options, one in which the tether adopts a position encircling adjacent the container neck portion, without protruding; and at least one further option in which the tether adopts an exposed state determining a protruding handle; and wherein the container neck portion defines a container opening, with a central axis, and is provided with an external thread formation including a reference finish lead and at least a first and a second auxiliary finish leads in a counterclockwise order; and
wherein the closure shell comprises a top wall portion and an annular skirt portion with an internal thread formation mating with the external thread formation of the neck portion and including a reference closure lead and at least a first and a second auxiliary closure leads in a counterclockwise order; and
wherein, when the closure shell is screwed on to the container neck portion during a re-closing operation of the container opening by engaging the reference closure lead of the closure shell with the first auxiliary finish lead instead of engaging with the reference finish lead of the container neck portion, the tether adopts an exposed state determining a protruding handle.
