ABSTRACT:
The cap assembly comprises: a cap which when unscrewed causes a detachment or distancing of a safety strip from the cap; and a convex seal which, when the cap assembly is inserted on a bottle, is deformed by internal pressure in the bottle and guarantees a seal on an internal wall of a bottle neck, even when there are small axial movements of the cap assembly with respect to the bottle neck.
