A tamperproof closure is disclosed for use with a container nozzle having a circular transfer bead. The closure includes a top and depending sidewalls which are defined from a bottom extension by a circular weakened seam. An interior groove is provided in the bottom extension of diameter less than the diameter of the transfer bead. A plurality of slots are formed in the bottom extension between the weakened seam and the interior groove to provide a degree of flexibility. The closure may be applied to the nozzle in either a threaded connection or in a snap ring connection. Upon opening the container, the frictional engagement between the transfer bead and the interior groove will cause the bottom extension to remain tightly affixed to the transfer bead, thereby causing the closure to sever along the weakened seam.
