Abstract

In order to facilitate the detection of any unauthorized opening of a sterilization container for surgical instruments or the like having a lower section, a cover sealingly placeable thereon, a locking member securing the cover in position on the lower section and pivotable between a closed position and an open position, and a card-like securing element which can be secured in position on the container and moves into the path of travel of the locking member near to the closed position of the locking member, it is suggested that the part of the securing element moving into the path of travel of the locking member be elastically bendable out of the plane of the securing element and move into the path of travel of the locking member only to such a depth that it slides back behind the locking member when the locking member is pivoted into the open position and during closing of the locking member is taken along with it and is covered by the locking member in the closed position thereof.

Claims

1. A sterilization container comprising:

a lower section;

a cover sealingly placeable on said lower section;

a locking member securing the cover in position on the lower section and mounted on one of said cover and lower section for pivotable movement between a closed position and an open position;

a card-like securing element positionable on one of said cover and lower section of the container and having a portion movable into a path of travel of said locking member;

said movable portion being elastically bendable out of the plane of the rest of said securing element for placement into the path of travel of the locking member only to such an extent that it slides behind the locking member when the locking member is pivoted into an open position, said locking member upon closing causing said movable portion of the securing element to move along said path of travel such that said movable portion is covered by said locking member when said locking member reaches said closed position.

2. A sterilization container as defined in claim 1 wherein said movable portion comprise a tongue protruding laterally from said card-like securing element.

3. A sterilization container as defined in claim 1 further comprising a holder for said card-like securing element, said holder being arranged next to said locking member for receiving said securing element when said locking member is closed, with said movable portion positioned directly in front of said locking member.

4. A sterilization container as defined in claim 3 wherein said movable portion is bent forwardly out of said plane by abutment with said locking member when the card-like securing element is inserted into said holder.

5. A sterilization container as defined in claim 3 wherein said locking member includes a deflecting surface for deflecting said movable portion of said card-like securing element in front of the locking member during insertion of said securing element into said holder.

6. A sterilization container as defined in claim 3 wherein said holder comprises an insertion slot for said securing element, said insertion slot being provided at a side of said holder opposite said locking member.

7. A sterilization container as defined in claim 6 wherein said insertion slot is laterally offset in relation to the plane in which the securing element is held in said holder.

8. A sterilization container as defined in claim 3 further comprising means operatively associated with said locking member for holding said securing element down in a position towards said sterilization container, said holding down means being arranged in front of a portion of said securing element next to said movable portion thereof.

9. A sterilization container as defined in claim 8 wherein said holding down means are part of said locking member.

10. A sterilization container as defined in claim 9 further comprising:

a gap arranged in said locking member and extending parallel to the direction of insertion of said securing element;

said holding down means covering said securing element being arranged on one side of said gap; and

a part of said locking member being arranged on the other side of said gap and under the securing element;

said part of said locking member being designed and positioned to slide past the securing element when the locking member is opened and to cover the securing element once the locking member has been closed again.

11. A sterilization container as defined in claim 8 wherein said holding down means are part of the holder for the securing element.

12. A sterilization container as defined in claim 1 wherein:

said movable portion is connected to the rest of said securing element via a first connection having a predetermined breaking point, and a second stronger, flexible connection;

said predetermined breaking point of said first connection is designed and positioned such that said first connection breaks when the locking member moves said movable portion when pivoted into said open position; and

said second connection is designed and positioned such that it remains intact when said first connection breaks.

13. A sterilization container as defined in claim 12 further comprising a holder for said card-like securing element, said holder being arranged next to said locking member for receiving said securing element when said locking member is closed, with said movable portion positioned directly in front of said locking member.

14. A sterilization container as defined in claim 13 wherein said movable portion is bent forwardly out of said plane by abutment with said locking member when the card-like securing element is inserted into said holder.

15. A sterilization container as defined in claim 12 wherein

said first connection comprises a connecting web having a first width;

said second connection comprises a connecting web having a second width; and

said first width is different from said second width.

16. A sterilization container as defined in claim 15 wherein said locking member bears a lateral extension engaging between the connecting webs for tearing the narrower one of said webs when the locking member is pivoted into said open position.

17. A sterilization container as defined in claim 12 wherein an opening is arranged in said securing element next to said movable portion, said opening defining said first connection and said second connection between said movable portion and the rest of the securing element;

wherein

said first connection comprises a connecting web having a first width,

said second connection comprises a connecting web having a second width; and

said first width is narrower than said second width.

18. A sterilization container as defined in claim 17 wherein said locking member bears a lateral extension engaging between the connecting webs for tearing said narrow web when the locking member is pivoted into said open position.

19. A sterilization container as defined in claim 12 further comprising means operatively associated with said locking member for holding said securing element down in a position towards said sterilization container, said holding down means being arranged in front of a portion-of said securing element next to said movable portion thereof.

20. A sterilization container as defined in claim 1 wherein said locking member bears a marking member for penetrating and damaging said securing element during pivoting of the locking member out of the closed position into the open position.

21. A sterilization container as defined in claim 1 further comprising:

means operatively associated with said locking member for holding said securing element down in a position towards said sterilization container, said holding down means being arranged in front of a portion of said securing element next to said movable portion thereof;

wherein said holding down means secure the securing element in a position such that a region of the securing element which is located between a region covered by said holding down means and a region located in front of said locking member is biased in an outward direction away from the sterilization container.
