Patent attributes
A closure assembly with a spout having a body with a seal portion and a tubular neck, and, a rotational plastic cap having a top wall, a downward depending skirt and opposite wing parts, extending in a vertical plane from the skirt over a wing part length. The top portion of the wing parts has a top protrusion extending from the base portion. The top protrusion extends substantially in and/or opposed to the opening direction of the cap such that the top portion of the wing parts extends along the wing part length over/outside the base portion thereof in a direction corresponding or opposed to the opening direction, such that, for a cross-section in a vertical plane of the opening direction, the surface area of the at least one top protrusion contributes at least equally to the inertial moment as the surface area of the base portion.
