Abstract
A tamper indicating closure includes a one-piece cap having a dispensing outlet which is aligned with a dispensing outlet in the neck of a bottle upon rotation of the cap. A removable tamper resistant detent extends downwardly from the top end of the cap and nests with a recess in the upper edge of the neck of the bottle to prevent rotation of the cap. The removable tamper resistant detent is torn free of the cap such that the cap can be rotated to an open position. The closure may also contain a flexible spout which can be folded outwardly by rotation of the cap to an open position.
