Bag seal has flexible hollow component, and at least one spring element installed on wall of hollow component and bendable to spring back so that hollow component is reversibly opened

摘要

The bag seal has a hollow component (2) in the form of a sleeve manufactured from a flexible material, and the walls (5) of which in the closed state lie one upon the other, and in the open state are spaced apart. At least one spring element (4) is installed on the wall and is bendable to spring back so that the hollow component is reversibly opened. The length of the spring element corresponds approximately to half the circumference of the hollow component. Spring elements may be provided on the inner side of the wall or on the outer side, and glued, stitched or welded to it. An Independent claim is included for a procedure for the filling of a bag in which the spring element is compressed by a force so that the hollow component forms an opening to accept a filling connector.
