ABSTRACT:
A shaker cap having a cover which can be opened easily and is adapted to close automatically. The cap includes a cylindrical cap body having a top wall formed with holes and a threaded portion threaded onto the mouth of a shaker. The holes of the cap body are opened and closed by a cover. The cover is coupled to a control piece through gear engagement so that when the control piece is pressed, the cover pivots open. As soon as the pressure on the control piece is removed, the control piece spontaneously moves back to the original rest position biased by a spring piece. The cover thus pivots shut.
