Abstract
This invention is related to an improved, non-refillable and inviolable cap for bottles and other similar containers, featured by a combination of the following components: a valve-seat designed to be hermetically coupled to the container's mouth, same which encompasses a valve-seat flexible flange, a hollow bottom, a guiding, central-vertical projection, and a vertical, annular retention-member, with an interlocking-surface on one end; a valve formed by an elongate body with a central, vertical cavity on its lower end, which loosely receives the vertical projection of the seat; and a conical sealing-wall that surrounds the body and rests upon the valve-seat flange; an externally-threaded spout including an internal interlocking-surface, which cooperates with the interlocking-surface of the seat's retention-member , an external, intermediate and downward-oriented interlocking-surface; a plurality of protuberances (legs), all with external interlocking-surfaces on their lower ends; and an internal, central ring pending from the upper wall, aimed to guide and retain the valve when this is open.
