Abstract

A container enclosing an applicator and a dental composition including a volatile organic solvent. The container is sealed. The volatile organic solvent is effectively retained within the container, even after storage at about 43° C. for one week. Preferably the container is made of a copolymer of a cycloolefin and an open chain olefin.

10. The storage stable enclosed dental composition of claim 1 wherein said packaged dental composition is at least 20 percent by weight acetone both before and after storage at about 23°

C. for one year and at least 90 percent of said acetone remains in said container after said storage.

11. The storage stable enclosed dental composition of claim 1 wherein said packaged dental composition is at least 40 percent by weight acetone both before and after storage at about 23°

C. for two years and at least 95 percent of said volatile organic solvent remains in said container after said storage.

12. The storage stable enclosed dental composition of claim 1 wherein said packaged dental composition is at least 40 percent by weight acetone both before and after storage at about 23°

C. for one year and at least 90 percent of said acetone remains in said container after said storage.

13. The storage stable enclosed dental composition of claim 1 wherein said packaged dental composition is at least 50 percent by weight acetone both before and after storage at about 23°

C. for two years and at least 95 percent of said volatile organic solvent remains in said container after said storage.

14. The storage stable enclosed dental composition of claim 1 wherein said packaged dental composition is at least 50 percent by weight acetone both before and after storage at about 23°

C. for one year and at least 90 percent of said acetone remains in said container after said storage.

15. The storage stable enclosed dental composition of claim 1, wherein said container wall has a second outer flange.

16. The storage stable enclosed dental composition of claim 15, wherein said elongated arm extends through said container and said elongated arm is supported by said container.

17. The storage stable enclosed dental composition of claim 15, wherein said closure is supported by at least one outer flange.

18. The storage stable enclosed dental composition of claim 1 wherein said container has an outer wall with a groove, and said container wall is adapted to break open along said groove.

19. The storage stable enclosed dental composition of claim 18, wherein said groove forms a line extending circumferentially around said container.

20. A stored enclosed dental product made by the process comprising:

enclosing an applicator and a dental composition having at least one volatile component in a container, said container comprising thermoplastic polymer having a high chemical resistance and a high permeability barrier capability for water, and
