Abstract

The underside of the cap is attached by connectors to the top of a locking ring, having an internal bead-shaped thickened portion with a top face working against a bead on the bottle, the internal diameter of the locking ring top end being greater than the external diameter of the base of the cap. The top face of the internal bead forms part of a conical surface with an apex angle of 160 deg. at the most, and works with the bottom face of the bead on the bottle. The quantity of material in the internal bead can be such as to match the diameter of the sealing ring and the elasticity of the plastic used. The connectors can be of triangular section, two sides being joined respectively to the base of the cap and the top of the locking ring. When the cap is fitted in place they withstand the pressure necessary to force the locking ring over the bottle bead.
