Abstract

A pharmaceutical container with an improved peelable seal is provided, wherein the container is may be made of a flexible polymeric film and comprises at least one peelable seal comprising at least two substantially straight sections (7, 8) which are connected by a rupture zone (5), characterized in that the. The rupture zone (5) of the peelable seal is may be curved over its whole length between the straight sections (7, 8). The container is may be used for storing pharmaceutical substances, solutions for dialysis, solutions for infusion and/or agents for nutrition.

Claims

1-13. -13. (canceled)

14. A container made of a flexible polymeric film for storing pharmaceutical agents, comprising at least one peelable seal, the at least one peelable seal including at least two substantially straight sections connected by a curved rupture zone, the curved rupture zone curving its entire length between the at least two substantially straight sections.

15. The container according to claim 14, wherein the curved rupture zone forms an arc of a circle having a radius of 5 to 75 mm, the radius extending from the center point of the circle to a point on an outer edge of the at least one peelable seal.

16. The container according to claim 14, wherein the curved rupture zone is an arc of a circle with a radius of 10 to 30 mm.

17. The container according to claim 15, wherein the curved rupture zone is an arc of a circle with a radius of 20 to 25 mm.

18. The container according to claim 15, wherein the arc of the circle has a central angle of at least 60°

.

19. The container according to claim 15, wherein the arc of the circle has a central angle of 64°

to 180°

.

20. The container according to claim 14, wherein the curved rupture zone is S-shaped.

21. The container according to claim 14, wherein the at least two substantially straight sections are parallel to each other and the distance between the at least two substantially straight sections is from 5 to 75 mm.

22. The container according to claim 14, wherein the at least two substantially straight sections are in line with each other.

23. The container according to claim 14, wherein a seal width of the at least two substantially straight sections and the rupture zone is from 2 to 10 mm.

24. The container according to claim 14, wherein the container comprises a polymeric film, the container including a first region forming an outside area and a second region forming a sealing inside area, the first region having a higher melting point than the second region, wherein the second region forming the sealing inside area is structured to form both permanent seals and peelable seals when subjected to different welding conditions.

25. The container according to claim 24, wherein the polymeric film comprises at least two layers including an inside layer that is a sealant layer structured to form both permanent seals and peelable seals when subjected to welding at different temperatures.

26. The container according to claim 14, wherein in the container is configured to store at least one of pharmaceutical substances, solutions for dialysis, solutions for infusion and agents for nutrition.

27. A container made of a flexible polymeric film for storing pharmaceutical agents, comprising at least one peelable seal, the at least one peelable seal including at least two substantially straight sections connected by a curved rupture zone, the at least two substantially straight sections parallel to each other and the curved rupture zone curving its entire length between the at least two substantially straight sections.
