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.

Abstract: A pasteurized to raw liquid processing system for milk or milk products includes top and bottom tanks, one elevated above the other approximately two feet. The tanks are vented to atmosphere. To prevent foaming, the inlet from a pasteurized source to the top tank is below the liquid level and the same is true of the inlet to the bottom tank which via a throttle valve receives liquid from the bottom of the top tank. Automatic feedback level controls are provided. Since both tanks are vented to atmosphere and because of the gravity flow between the top and bottom tanks, it is impossible to have a vacuum or pressure buildup which would cause a contaminating back flow.

Abstract: In order to automatically carry out the emptying and rinsing of non-recoverable bottles or flasks (78) made from a perforatable material such as polyethylene and e.g. containing a low activity solution (88), an apparatus is proposed making it possible to pass the inverted bottles under a double-walled needle (44). The needle (44), operated by a jack, perforates the bottom (82) of the flask (78). Compressed air is then injected into the bottle above the solution (88) through the annular passage formed between the walls of the needle (44), so as to discharge the solution through the central passage of the needle. The flask is then rinsed by injecting pressurized water in place of the compressed air. Finally, the rinsing water is discharged by a further compressed air injection. The emptied and rinsed flasks are then passed to a station, where they are directly discharged into a storage drum.
