Abstract
A rupturable stopper for a pouring spout for a receptacle includes a base having a pouring zone sealed closed by a cover connected to the base by frangible connection. The spout includes a tubular neck having internal screw threads connected to the base so as to surround the frangible connection and terminating at a pouring lip. A cylindrical appendage extending up from the cover lies concentrically within the neck and receives a closure cap thereon that includes screw threads engageable with the neck and a seal that engages a spout pouring lip when the cap is engaged with the spout neck. Interlocking elements between the cap and the appendage prevent reverse rotation of the cap relative to the appendage so that, once the cap is secured in place within the neck by the screw threads, the first attempt to remove the cap drives the appendage in a twisting and axial movement to cause rupture of the frangible connection to open the pouring zone of the base. Reapplication of the cap in the neck reseals the pouring zone with the original cover and also seals the spout along the lip area of the neck.
