Abstract

A closure for a container is disclosed. The closure includes a cap seal and an overcap removably fastened to the cap seal, where the overcap includes a decorated film fused into a top surface of the overcap.

Claims

1. An overcap for a container comprising:

a button-like member having a generally flat top surface; and

a decorated film fused into the top surface, said decorated film including at least one first image on a top side of the decorated film in a top layer; and

a second image in a layer under the top layer which is visible only while being illuminated with radiation having a predetermined wavelength which is outside the spectral range of daylight.

2. The overcap of claim 1, wherein the decorated film comprises a silica filled micro-porous substrate.

3. The overcap of claim 1, wherein the at least one first image is visible to the naked eye when illuminated with light having a spectra which is substantially that of daylight.

4. The overcap of claim 3, wherein the at least one of the first and the second images image is fixed to the top side of the decorated film by a process selected from the group consisting of lithography, gravure, and flexography.

5. The overcap of claim 1, wherein the at least one first image is invisible to the naked eye when illuminated with light having a spectra which is substantially that of daylight.

6. The overcap of claim 5, wherein the at least one invisible second image is made visible to a person by illuminating the image with radiation of a predetermined wavelength.

7. The overcap of claim 1, wherein a portion of the top layer is transparent to radiation of a selected range of wavelengths.

8. The overcap of claim 1, wherein the film includes at least one image which is visible when illuminated with light having a spectra which is substantially that of daylight and at least one image which is invisible when illuminated with light having a spectra which is substantially that of daylight.

9. The overcap of claim 1, wherein the at least one of the first and second images image includes covert information.

10. The overcap of claim 1, further including a memory device attached to a bottom side of the film.

11. The overcap of claim 10, wherein information stored in the memory device may be wirelessly read.

12. The overcap of claim 11, wherein the memory device is a radio frequency identification device.

13. The overcap of claim 11, further including an antenna attached to the bottom side of the film and connected to the memory device.

14. The overcap of claim 13, wherein the memory device and the antenna are attached to the film by an adhesive.

15. The overcap of claim 13, wherein the antenna is printed on the decorated film.

16. The overcap of claim 10, wherein the memory device includes a stored character sequence unique to the memory device, which is capable of being wirelessly read and incapable of being altered.

17. The overcap of claim 10, wherein the memory device attached to the overcap remains fully functional for reading and for writing following exposure to a temperature of about 121 degrees Celsius for at least twenty minutes.

18. The overcap of claim 10, wherein the memory device attached to the overcap remains fully functional for reading and for writing following exposure to a temperature of about minus 80 degrees Celsius for at least one month.

19. The overcap of claim 1, wherein each one of the at least one images is legible following exposure of the overcap to a temperature of about 121 degrees Celsius for at least twenty minutes.

20. The overcap of claim 1, wherein each one of the at least one images is readable following exposure to a temperature of minus 80 degrees Celsius for at least one month.

21. The overcap of claim 1, wherein each one of the at least one images is readable following exposure to a sterilizing method selected from the group consisting of gamma radiation, e-beam radiation and ethylene oxide gas.

22. The overcap of claim 1, wherein the top layer includes an opaque portion including the first image and a window portion through which the second image is visible when illuminated with radiation having the predetermined wavelength.

23. A method of fabricating an overcap for a medicament container comprising the steps of:

forming a plurality of arrangements of at least one image on a top side of a substrate;

attaching a plurality of memory devices on a bottom side of the substrate such that the plurality of arrangements and the plurality of memory devices are aligned;

removing each one of the aligned arrangements and the memory devices from the substrate to form a plurality of decorated films;

forming a plurality overcaps by inserting each of the plurality of decorated films into a mold with a top side of the decorated film adjacent to a wall of the mold; and

injecting a polymeric material into the mold to form the overcap, wherein the decorated film is fused into a top surface of the overcap.

24. The method of claim 23, wherein the decorated film is held to the wall of the mold by an electrostatic charge during the step of injecting the polymeric material into the mold.

25. A closure for a container comprising:

a cap seal having an annular center section; and

an overcap removably fastened to the cap seal, said overcap having a decorated film fused into a top surface, said overcap including a depending projection adapted to engaging the annular center section, the annular center section separating from the cap seal and remaining with the overcap when the overcap is removed from the cap seal.

26. The closure of claim 25, wherein said overcap includes a decorated film fused into a top surface, the decorated film including at least one image.

27. The closure of claim 26, wherein the at least one image includes an image which is visible to a person when the overcap is illuminated with light having a spectra which is substantially that of daylight and an image which is invisible to a person when the overcap is illuminated with light having a spectra which is substantially that of daylight but is visible with when the overcap is illuminated with radiation of a predetermined wavelength outside the visible spectrum.

28. The closure of claim 26, wherein the decorated film includes at least one image on a top side and an electronic memory device on a bottom side.

29. The closure of claim 28, wherein the electronic memory device is a radio frequency identification device.

30. A method of establishing traceability of the contents of a container, the method comprising the steps of:

storing in a memory device capable of being wirelessly read, an unalterable character string, the character string being uniquely associated with the memory device; and

attaching the memory device to the container substantially concurrently with filling the container with the contents such that the stored character string is uniquely identified with the container, wherein the filled container is thereafter exposed to sterilization, and wherein the memory device remains fully functional after the container is exposed to the sterilization.

31. The method of claim 30, wherein the memory device is a radio frequency identification device.

32. The method of claim 30, further including the step of reading the character string for identifying the contents of the container when preparing a paper label to be applied to the container.
