Abstract

A container includes a cup and a lid. The lid is adapted to mate with a brim included in the cup to close a top aperture opening into an interior liquid-storage region formed in the cup.

First claim

The invention claimed is:

1. A lid for a cup, the lid comprising
a ring-shaped brim mount having a round shape with a center point located on a central axis of the lid, the ring-shaped brim mount being adapted to couple to a brim included in a cup,
a central closure coupled to the ring-shaped brim mount and adapted to close a top aperture opening into an interior liquid-storage region formed in the cup, and
a deformable product-identification dome coupled to the central closure, the deformable product-identification dome arranged to move from a first arrangement in which the deformable product-identification dome extends upwardly away from the central closure to a second arrangement in which the deformable product-identification dome is arranged to extend downwardly away from the central closure in response to a downward deformation force being applied to the deformable product-identification dome,
wherein the lid comprises polypropylene and the deformable product-identification dome has a first transparency in the first arrangement and a second transparency in the second arrangement and the second transparency is different than the first transparency,
wherein the lid comprises at least 49% by weight polypropylene.

2. A lid for a cup, the lid comprising
a ring-shaped brim mount having a round shape with a center point located on a central axis of the lid, the ring-shaped brim mount being adapted to couple to a brim included in a cup,
a central closure coupled to the ring-shaped brim mount and adapted to close a top aperture opening into an interior liquid-storage region formed in the cup, and
a deformable product-identification dome coupled to the central closure, the deformable product-identification dome arranged to move from a first arrangement in which the deformable product-identification dome extends upwardly away from the central closure to a second arrangement in which the deformable product-identification dome is arranged to extend downwardly away from the central closure in response to a downward deformation force being applied to the deformable product-identification dome,
wherein the lid comprises polypropylene and the deformable product-identification dome has a first transparency in the first arrangement and a second transparency in the second arrangement and the second transparency is different than the first transparency,
wherein the lid comprises at least 49% by weight a polypropylene impact copolymer.

3. The lid of claim 2 , wherein the lid comprises at least 99% by weight the polypropylene impact copolymer.

4. The lid of claim 3 , wherein the first transparency is defined at least by having a clarity greater than about 50% as measured using ASTM D 1746.

5. The lid of claim 4 , wherein the first transparency is defined at least by having a haze less than about 40% as measured using ASTM D 1003 procedure B.

6. The lid of claim 1 , wherein the lid comprises at least 99% by weight polypropylene.

7. The lid of claim 1 , wherein the first transparency is defined at least by having a clarity greater than about 50% as measured using ASTM D 1746 and the first transparency is defined at least by having a haze less than about 40% as measured using ASTM D 1003 procedure B.

8. The lid of claim 1 , wherein the lid is made of non-aromatic materials.

9. The lid of claim 1 , wherein the polypropylene is a polypropylene impact copolymer.

10. The lid of claim 9 , wherein the first transparency is defined at least by having a clarity greater than about 50% as measured using ASTM D 1746.

11. The lid of claim 10 , wherein the first transparency is defined at least by having a haze in a range of about 10% to about 60% as measured using ASTM D 1003 procedure B.

12. The lid of claim 11 , wherein the lid comprises at least 99% by weight the polypropylene impact copolymer.

13. A lid for a cup, the lid comprising
a ring-shaped brim mount having a round shape with a center point located on a central axis of the lid, the ring-shaped brim mount being adapted to couple to a brim included in a cup,
a central closure coupled to the ring-shaped brim mount and adapted to close a top aperture opening into an interior liquid-storage region formed in the cup, and
a deformable product-identification dome coupled to the central closure, the deformable product-identification dome arranged to move from a first arrangement in which the deformable product-identification dome extends upwardly away from the central closure to a second arrangement in which the deformable product-identification dome is arranged to extend downwardly away from the central closure in response to a downward deformation force being applied to the deformable product-identification dome,
wherein the deformable product-identification dome has a first transparency in the first arrangement, a second transparency in the second arrangement, the second transparency is different than the first transparency, and the first transparency is defined at least by having a clarity between about 50% and about 95% as measured using ASTM D 1746,
wherein the deformable product-identification dome includes a cap and a plurality of panels arranged around the cap and adjacent panels are coupled to one another to form stress concentrator joints, wherein the cap includes an upper surface, a lower surface, and a side surface that extends between and interconnects the upper surface and the lower surface, the side surface couples to the upper surface at a curved edge, and the lower surface couples to the plurality of panels at curved edges.

14. The lid of claim 13 , wherein the lid comprises polypropylene.

15. The lid of claim 14 , wherein the lid comprises at least 49% by weight a polypropylene impact copolymer.

16. The lid of claim 15 , wherein the lid comprises at least 99% by weight the polypropylene impact copolymer.

17. The lid of claim 15 , wherein the first transparency is defined at least by having a haze less than about 40% as measured using ASTM D 1003 procedure B.

18. A lid for a cup, the lid comprising
a ring-shaped brim mount having a round shape with a center point located on a central axis of the lid, the ring-shaped brim mount being adapted to couple to a brim included in a cup,
a central closure coupled to the ring-shaped brim mount and adapted to close a top aperture opening into an interior liquid-storage region formed in the cup, and
a deformable product-identification dome coupled to the central closure, the deformable product-identification dome arranged to move from a first arrangement in which the deformable product-identification dome extends upwardly away from the central closure to a second arrangement in which the deformable product-identification dome is arranged to extend downwardly away from the central closure in response to a downward deformation force being applied to the deformable product-identification dome,
wherein the deformable product-identification dome has a first transparency in the first arrangement, a second transparency in the second arrangement, the second transparency is different than the first transparency, and the lid comprises a polypropylene impact copolymer,
wherein the lid further comprises a polypropylene homopolymer,
wherein the lid comprises at least about 45% by weight the polypropylene impact copolymer.

19. The lid of claim 18 , wherein the lid further comprises a polypropylene random co-polymer.

20. The lid of claim 19 , wherein the lid comprises about 1% to about 15% by weight the polypropylene random co-polymer.
