Abstract
A bottle cap includes a mouthpiece having a dispensing orifice, a collar which extends downward from the mouthpiece to engage the bottle, a cover connected to the collar by a hinge and movable between open position and closed position covering the orifice, and a tamper-evident strap connecting the closed cover to the collar. The strap is hingeably joined to the collar by a lower portion of the strap and connected to the cover by a barbed upper portion. The upper portion cooperates with the cover to retain the strap to prevent manipulation of the strap to open the cover without severing the strap. The strap has a severable mid point which severs when the cover is first opened. When the cover is opened, both portions of the strap remain attached to the bottle and the lower portion swings away from the collar providing visible evidence of prior opening.
