ABSTRACT:
An apparatus for preventing the refilling and reuse of a container after it has dispensed its original contents without being evident of tampering. Refilling is prevented by a lockout device having an armed position and a closed position. The lockout device is in the armed position until attached to a filling apparatus. The pressure caused by a carrier dispensed from the apparatus through the lockout device causes the lockout device to spin to a closed and locked position. In the closed and locked position, the container cannot be refilled. A seal is provided above the lockout device and the device can only be rearmed and container refilled after the seal has been removed.
