Abstract: This invention describes a cap with a lid for hermetic seal tamper-proof security elements that includes a collar with an mounting portion to place and keep the cap fixed on the container and a sealing portion that enables to have hermetic sealing to prevent the contents of the container from spilling, getting contaminated or volatilizing; a lid for hermetic seal with tamper-proof security elements that has a round flat wall and a flap that runs downwards in a circular and perpendicular way from the round flat wall of such lid. The sealing portion of the collar is located adjacent to the stop wall of the mounting portion where the sealing portion is integrally formed with the stop wall of the mounting portion which is an arched wall running downwards from the stop wall. The flap of the lid has an interior diameter and an exterior diameter and in its lower end it has a portion of a rim which creates hermetic sealing through the sealing portion of the collar.

Abstract: Exterior radial or tangential openings are cut or molded within a bowling pin base insert which permit the exterior plastic coat during the injection molding process to flow into such openings and, upon hardening, form a tight and rotationally secure locking arrangement between the base insert, the exterior plastic coat and the wooden pin core, said bowling pin base insert having an interior annular recess to provide expansion space for the bowling pin wood core.
