Abstract

Improvements in the plugs and connection sleeves for the emptying of viscous liquids containers, characterized in that a cylindrical sleeve opened at one of its ends and internally threaded is introduced from the outside into the opening of the lateral surface of the container. Externally. The threaded part protrudes from the inner side of the container, while the opposite end has a perimetral rim acting as an outer retaining flange, which is applied to the outer surface of the container. In the area of the perimeter flange, the hole is closed by a disk limited by a circular race that constitutes the cutting line when you want to use the contents of the container. To the external threaded surface projecting on the inner side of the container, an internally threaded ring is mounted which has, on its external face, radial fins to facilitate the threading, with which the ring is introduced, threaded on the external thread of the sleeve until its smooth face is applied on the inner side of the container. The rotation of the ring in the threading operation is prolonged until it is compressed if edge of the hole of the container, so as to guarantee the tightness of the container. The opening of the container is effected by acting with a cutting instrument in the perimeter notch that points out the cutting line for the closing disk of the container so that, when rotating the closing disk of the sleeve, the perimeter flange or outer mouth will be mounted, the inner and outer threaded sleeve and the threaded inner ring.
