Closure device for containers for transporting radioactive substances
A closure device for containers for transporting radioactive substances, having a first and a second component each with a comb-like portion, wherein the comb-like portions, with the closure device locked, has a bolt element passing through them. The bolt element has a head with an accommodating recess running transversally to the longitudinal axis of the bolt element, that one of the components has a through-opening which, with the bolt passing through the comb-like portions, is aligned with an accommodating recess.
1. A locking mechanism comprising:
a first component having a first comb-like section;
a second component having a second comb-like section;
a bolt element comprising a head portion having a plurality of faces, and a shaft portion extending from a first face of the head portion;
a recess in the head portion, said recess extending perpendicularly to a longitudinal axis of the bolt element;
wherein the shaft portion is configured to pass through the first comb-like section and second comb-like section when the locking mechanism is in a locked position;
wherein the first comb-like section and the second comb-like section form a common longitudinal plane when the locking mechanism is in the locked position;
wherein the first face of the bolt element abuts a surface of the first comb-like section when the locking mechanism is in the locked position;
wherein the first component comprises an opening that is aligned with the recess in the head portion when the shaft portion is disposed within the first comb-like section and second comb-like section;
wherein the opening runs parallel to the common longitudinal plane; and
a locking element configured to be disposed in the opening;
wherein a portion of the locking element extends into the recess in the head portion when the locking mechanism is in the locked position.
2. The locking mechanism according to claim 1 ,
wherein the head portion comprises first and second opposing sections having a rectangular cross-section; and
wherein said first and second opposing sections extend symmetrically relative to a longitudinal axis of the bolt element, and project beyond a circumference of the shaft portion.
3. The locking mechanism according to claim 2 ,
wherein the first component comprises a first groove-like recess that is configured to receive the first opposing section having a rectangular cross-section; and
wherein the second component comprises a second groove-like recess that is configured to receive the second opposing section having a rectangular cross-section.
4. The locking mechanism according to claim 2 , wherein the recess in the head portion is in the first opposing section or the second opposing section of the head portion.
5. The locking mechanism according to claim 1 , wherein the head portion comprises a second recess in the second opposing section.
6. The locking mechanism according to claim 1 , wherein the locking element is a screw locking element.
7. The locking mechanism according to claim 1 , wherein the locking element comprises a head having an unconventional shape, such that a special tool is required to release the locking element.
8. The locking mechanism according to claim 1 , wherein the first comb-like section extends from a first longitudinal surface of a cuboid portion of the first component; and wherein the second comb-like section extends from a second longitudinal surface of a cuboid portion of the second component.
9. The locking mechanism according to claim 8 , wherein the opening extends from an outer surface of the first component to the first longitudinal surface.
10. The locking mechanism according to claim 1 , wherein the first component and the second component are manufactured from steel.
11. In combination, the locking mechanism of claim 1 and a container for transporting a radioactive substance.
