A plastic cap has a tearable outer skirt depending from a top disc, the interior of the skirt having means engaging with cooperating means on a container neck to hold the cap in place until the lower portion of the skirt is torn. To prevent dishonest persons from defeating the tamper resistant character of the cap by prying upward on the bottom edge of the cap skirt, a shoulder has been formed on the neck fitting closely under the bottom edge of the cap skirt. To further reduce such prying, a series of protrusions is formed on the shoulder with spaces between the protrusions. The protrusions inhibit fingernails from access to the lower edge of the skirt. The bumper ring which cooperates with loading grippers is interrupted by straight sections which prevent collapse of the bumper ring when the cap is applied.
