A cap for writing implements comprises a hollow lower body jointed at one end to a hollow upper body, ending on top with a closed end having a smaller section; openings for the communication of the lower inner hollow body with the outside are obtained in correspondence with the jointed length; said openings alternate to sides extending from said jointed length, which are substantially parallel to the hollow upper body to form ducts stretching out towards said closed end where further communication openings are realized between the inner lower hollow body and the outside.
