A tamper-proof seal is disclosed for use in connection with sterilization containers. The seal includes a body portion including a sterilization indicating material and a tongue extending from the body portion. The tongue may be in the form of a laminate consisting of a pair of substantially inert outer layers sandwiching a high shrink inner layer. The tongue is designed to engage the latch mechanism of a sterilization container when the container is in the closed position and the latch mechanism is in a latched position. Upon exposure of the container to sterilization conditions, the tongue shrinks, causing the outer layers to fold upon themselves to form at least one pleat. The container latch mechanism cannot be opened without fracturing the tongue of the seal, thereby providing visible evidence of the latch mechanism being opened.

The invention claimed is: 1. A disposable seal for a container having a latch mechanism, comprising a body; and a tongue having one end connected to said body and a free end, said tongue including a layer of a material which shrinks under sterilization conditions, said shrinkable material having first and second surfaces; said tongue including at least one layer of a second material laminated to said first surface of said shrinkable material. 2. The disposable seal as claimed in claim 1, wherein said shrinkable material is a heat shrinkable material. 3. The disposable seal as claimed in claim 2, wherein said heat shrinkable material is a heat shrink vinyl. 4. The disposable seal as claimed in claim 1, further comprising a weakened region between said body and said tongue. 5. The disposable seal as claimed in claim 1, wherein said body includes a sterilization indicator material. 6. The disposable seal as claimed in claim 5, wherein said sterilization indicator material comprises a sterilization indicating ink. 7. The disposable seal as claimed in claim 1, wherein said tongue has an initial length and a post-sterilization length which is less than said initial length. 8. The disposable seal as claimed in claim 7, wherein said initial length of said tongue is sufficient to permit the tongue to be assembled to the latch mechanism in a use position, and said post-sterilization length of said tongue is insufficient to permit said tongue to be assembled to the latch mechanism in said use position. 9. The disposable seal as claimed in claim 1, further comprising an adhesive for adhering said free end of said tongue to said body. 10. The disposable seal as claimed in claim 1, wherein said second material includes a weakened region between said one end and said free end. 11. The disposable seal as claimed in claim 10, wherein said tongue has a longitudinal direction between said one end and said free end, and said weakened region includes a series of at least three perforations in said second material, said perforations extending in a direction transverse to said longitudinal direction. 12. The disposable seal as claimed in claim 11, further comprising an adhesive for adhering said second material to said shrinkable material, said adhesive being excluded from said weakened region. 13. The disposable seal as claimed in claim 1, wherein said tongue includes at least one layer of a third material laminated to said second surface of said shrinkable material. 14. The disposable seal as claimed in claim 13, wherein said second and third materials each include a weakened region between said one end and said free end. 15. The disposable seal as claimed in claim 14, wherein said tongue has a longitudinal direction between said one end and said free end, and said weakened regions include a series of at least three perforations in each of said second material and said third material, said perforations extending in a direction transverse to said longitudinal direction. 16. The disposable seal as claimed in claim 15, wherein said perforations in said second material are in registry with said perforations in said third material. 17. The disposable seal as claimed in claim 13, wherein said second and third materials are selected from the group consisting of polymers. 18. The disposable seal as claimed in claim 13, wherein said second material is the same as said third material. 19. The disposable seal as claimed in claim 18, wherein said second and third materials are selected from the group consisting of polyolefins. 20. The disposable seal as claimed in claim 1, wherein said tongue has an initial thickness and a post-sterilization thickness which is greater than said initial thickness. 21. The disposable seal as claimed in claim 1, wherein said second material is selected from the group consisting of polymers. 22. The disposable seal as claimed in claim 21, wherein said second material is selected from the group consisting of polyolefins. 23. The disposable seal as claimed in claim 1, wherein said tongue has a selected width, and said body has a width which is greater than said selected width. 24. A disposable seal for a container, comprising a body including a sterilization indicating ink; and a tongue having one end connected to said body and a free end, said tongue having an initial length and a post-sterilization length which is less than said initial length. 25. A disposable seal for a container, comprising a body including a sterilization indicator material; and a tongue having one end connected to said body and a free end, said tongue having an initial thickness and a post-sterilization thickness which is greater than said initial thickness.
