ABSTRACT:
Provided is a convenient container cap which can be integrally molded from synthetic resin material, and comprises a primary cap adapted to be fitted on an opening of a container and provided with an outlet opening in a top wall thereof, and a secondary cap attached to the primary cap with a reversible hinge and provided with a plug member adapted to be fitted into the outlet opening of the primary cap. According to one aspect of the present invention, the reversible hinge comprises a resilient piece connected between the top wall 3 of the primary cap and an inner surface of the secondary cap, in each case, in a region located more radially inwardly that a flexible thinned hinge portion so that the external appearance of the reversible hinge is improved. According to another aspect of the present invention, a slide member is also integrally attached to the primary cap for reducing the effort required to open the secondary cap without increasing the number of component parts or complicating the assembling process.
