Abstract:
1. A cap arrangement, comprising an opening-indicator device having an outer edge wherefrom fin members lead away and extend, in use, internally of said cap arrangement, said fin members being intended to form an abutment for projection elements projecting from a neck of a container arrangement with which said cap arrangement can be associated, said fin members comprising an elongated element extending substantially rectilinearly from said opening-indicator device, said fin members further comprising flexible appendage elements forming a free end of said fin members, said elongated element having a first end connected with said opening-indicator device and a second end, opposite said first end, to which said appendage elements are connected, said flexible appendage elements having a substantially uniform thickness, said appendage elements leading away from said second end and being thinner than said second end such that said second end has, contiguously to said appendage elements in a direction of said uniform thickness, a zone of interaction adapted to abut against said projection elements, said first end comprising a deformable zone acting as plastic hinge to connect said elongated element to said opening-indicator device, said appendage elements being movable between a folded configuration in which, during the application of said cap arrangement to the neck of the container, said appendage elements are contained in the thickness of said elongated element, and an extended configuration in which said appendage elements extend substantially transversely from said elongated element and in which said appendage elements have a curved profile adapted to partially surround said projection elements when said zone of interaction abuts against said projection elements in such a way as to prevent overturning of said fin members around said deformable zone during the first opening of the container.
