ABSTRACT:
A device is provided which is non-removably mounted in the mouth of a bottle and which prevents or obstructs the addition of adulterating liquids to the contents of the bottle. The device includes a plastics tubular body 13 having detachably attached to its lower end a non-return valve comprising a ball 14 and a seating ring 15, and a baffle disc 18 formed integrally with the body covers the ball. The body 13 is secured in the bottle mouth by a flanged plastics collet 16 having at its lower end integral resilient tongues 31 which are forced into engagement with a shallow channel 11 on the internal surface of the neck by the act of pressing the body 14 and valve down into the position shown, the valve seating ring 15 having a frusto-conical external surface for this purpose. Upward movement of the body relative to the collet is prevented by a shoulder 22 on the body which comes into abutment with the lower ends of the tongues 31. Liquid can flow past the ball and the baffle to allow the bottle to be emptied but the valve prevents refilling of the bottle. Attempted interference with the ball valve from above can cause the valve to become detached from the body and fall into the bottle to provide visible evidence of tampering.
