Abstract

This invention is an improved collapsible cap that may be easily opened and closed so that when the cap is in a closed position the cap will be of relatively uniform height allowing the cap to be easily packed and stored. The apparatus of this invention accomplishes the foregoing by encapsulating the opening and closing mechanism of the cap, i.e., a hinge having a pivot pin in a plastic material and attaching one portion of the plastic material to the cap frame and another portion of the plastic material to a folded over encircling fabric tape containing a circular wire grommet.
