Claims for Patent: 7,866,474

Title:Film container
Abstract: A film container (FIG. 4) comprises two rectangular films (5) joined together at their periphery to form a receiving chamber (6) for a filling (7), particularly a pharmaceutical formulation of an active substance, at least one of said films (5) being provided, for the purpose of tearing it open, with a marking (13) formed within the connecting region, which is exposed after the films (5) have been bent. The marking (13) extends centrally between two opposing outer edges (11) of the film container (1).
Inventor(s): Geser; Johannes (Ingelheim, DE), Beyer; Sebastian (Eltville, DE)
Assignee: Boehringer Ingelheim International GmbH (Ingelheim, DE)
Application Number:11/305,365
Patent Claims: 1. A blister card comprising: a plurality of combined film containers, the containers operatively separated by intersecting perforations, each of the plurality of film containers comprising: two rectangular films joined together at their periphery to form a receiving chamber containing a pharmaceutical formulation of an active substance, at least one of the films being provided, for the purpose of tearing the at least one of the films open into and through the receiving chamber, with: (i) a cut formed within a connecting region, which cut, after the films have been bent, operates to tear into and through the at least one of the films of the receiving chamber such that an inner volume of the receiving chamber is exposed, wherein the cut extends centrally between two opposing outer edges of the film container; and (ii) an additional perforation for the controlled bending of the films provided parallel to, and at a spacing from, an associated outer edge of the film container, such that the cut is longer between the receiving chamber and the additional perforation than between the additional perforation and the associated outer edge.

2. The blister card according to claim 1, wherein the spacing of the additional perforation from the associated outer edge is less than a spacing from the receiving chamber.

3. The blister card according to claim 1, wherein the additional perforation divides the cut asymmetrically.

4. The blister card according to claim 2, wherein the additional perforation divides the cut asymmetrically.

5. The blister card according to claim 1, wherein a path of the cut between the receiving chamber and the additional perforation is longer than between the additional perforation and the associated outer edge.

6. The blister card according to claim 2, wherein a path of the cut between the receiving chamber and the additional perforation is longer than between the additional perforation and the associated outer edge.

7. The blister card according to claim 3, wherein a path of the cut between the receiving chamber and the additional perforation is longer than between the additional perforation and the associated outer edge.

8. The blister card according to claim 4, wherein a path of the cut between the receiving chamber and the additional perforation is longer than between the additional perforation and the associated outer edge.

9. The blister card according to claim 1, wherein the additional perforation divides the cut symmetrically.

10. The blister card according to claim 2, wherein the additional perforation divides the cut symmetrically.

11. The blister card according to claim 1, wherein the cut extends centrally with respect to the receiving chamber.

12. The blister card according to claim 2, wherein the cut extends centrally with respect to the receiving chamber.

13. The blister card according to claim 3, wherein the cut extends centrally with respect to the receiving chamber.

14. The blister card according to claim 9, wherein the cut extends centrally with respect to the receiving chamber.

15. The blister card according to claim 1, wherein the cut and the additional perforation extend at right angles to each other.

16. The blister card according to claim 2, wherein the cut and the additional perforation extend at right angles to each other.

17. The blister card according to claim 3, wherein the cut and the additional perforation extend at right angles to each other.

18. The blister card according to claim 9, wherein the cut and the additional perforation extend at right angles to each other.

19. The blister card according to claim 11, wherein the cut and the additional perforation extend at right angles to each other.

20. The blister card according to claim 1, wherein the cut is in the form of a notch.

21. The blister card according to claim 1, wherein the two films include a heat sealing lacquer for joining the two films together.

22. The blister card according to claim 1, wherein one film is constructed as a carrier film comprising the receiving chamber and the other film is constructed as a covering film.

23. The blister card according to claim 1, wherein the films are constructed as metal and/or plastics and/or paper films.

24. The blister card according to claim 1, wherein the additional perforation extends parallel to and at a spacing from a perforation which divides the blister card in its center.

25. The blister card according to claim 1, wherein the filling is a pharmaceutical formulation comprising dabigatran etexilate.

26. The blister card according to claim 3, wherein the filling is a pharmaceutical formulation comprising dabigatran etexilate.

27. The blister card according to claim 1, wherein the filling is a pharmaceutical formulation comprising dabigatran etexilate.

28. The blister card according to claim 5, wherein the filling is a pharmaceutical formulation comprising dabigatran etexilate.

29. A blister card comprising: a plurality of combined film containers, the containers operatively separated by intersecting perforations, each of the plurality of film containers comprising two rectangular films joined together at their periphery to form a receiving chamber containing a pharmaceutical formulation of an active substance, at least one of the films being provided, for the purpose of tearing the at least one of the films open into and through the receiving chamber, with: (i) a cut formed within a connecting region, which cut, only after the films have been bent, operates to tear into and through the at least one of the films of the receiving chamber such that an inner volume of the receiving chamber is exposed, wherein the cut extends centrally between two opposing outer edges of the film container; and (ii) an additional perforation for the controlled bending of the films provided parallel to, and at a spacing from, an associated outer edge of the film container, wherein the additional perforation divides the cut asymmetrically such that the cut has a greater length between the receiving chamber and the additional perforation than between the additional perforation and the associated outer edge.

30. The blister card according to claim 29, wherein the spacing of the additional perforation from the associated outer edge is less than a spacing from the receiving chamber.

31. The blister card according to claim 29, wherein the additional perforation divides the cut asymmetrically.

32. The blister card according to claim 29, wherein a path of the cut between the receiving chamber and the additional perforation is longer than between the additional perforation and the associated outer edge.

33. The blister card according to claim 29, wherein the cut extends centrally with respect to the receiving chamber.

34. The blister card according to claim 33, wherein the additional perforation divides the cut symmetrically.

35. The blister card according to claim 33, wherein the cut and the additional perforation extend at right angles to each other.

36. The blister card according to claim 29, wherein the cut is in the form of a notch.

37. The blister card according to claim 29, wherein the two films include a heat sealing lacquer for joining the two films together.

38. The blister card according to claim 29, wherein one film is constructed as a carrier film comprising the receiving chamber and the other film is constructed as a covering film.

39. The blister card according to claim 29, wherein the films are constructed as metal and/or plastics and/or paper films.

40. The blister card according to claim 29, wherein the additional perforation extends parallel to and at a spacing from a perforation which divides the blister card in its center.

41. The blister card according to claim 29, wherein the filling is a pharmaceutical formulation comprising dabigatran etexilate.
