Abstract: A captive cap for a screw-neck container, with a cap shell, a ring for the retaining thereof to the container, two articulable arms which at their forward extremities are linked to the cap shell and at their rearward extremities are linked to the ring, an upper frangible line extending circumferentially between 210° and 340° and defining a frontal separation between the forward extremities of between 150° and 20°, a lower frangible line extending circumferentially between 180° and 330°, where the lower frangible line comprises a recess located at the frontal separation and projecting toward the cap shell.

Abstract: A closure system having a container neck portion and a closure both with tread formations offering multiple angular distributed mutual engagement options. The closure has a closure shell and a tamper-evident band connected through frangible connections that break when the closure shell is fully unengaged for the first time forming an unattached tether. The tamper-evident band and a lodging section of the container neck portion are 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 opening operations of the container neck portion, and specific optimal sizing for the tether are selected, such that the closure system offers the user different re-closing options, at least one of which forces the tether to adopt an exposed state determining a protruding handle.
