HIGHLY SECURE CLOSURE FOR CONTAINERS, PIPES, AND CYLINDERS
The invention relates to the field of mechanical security, in particular a closure device for securely closing round, angular, and oval interiors. A closure device comprises a securing head (1) and a plurality of resistance elements (8) which protrude beyond the inner wall (23), wherein the securing head (1) has rotatably mounted securing locking elements (2) that have annular surfaces (2B), the respective section of which that faces the container is positioned below the retaining sides (8A) of the resistance elements (8) in the closure position, and the securing head (1) has recesses (9) which also pass through the securing locking elements (2) and which have a cross-section that corresponds to the paired resistance element (8). Furthermore, multiple locking surfaces (2C) which are distributed over the edge region and which have a cross-section that corresponds to the paired resistance element (8) are arranged on a respective annular surface (2B).
