Abstract

A container and product system comprising a container adapted to house a product, the container comprising a substantially transparent multi-layered laminate body and a product housed in the container, the product comprising dyes, lakes, or both.

First claim

We claim:

1. A dentifrice container and product system comprising
(a) a tubular container adapted to house a product, the container comprising a substantially transparent multi-layered laminate body comprising a surface layer, a layer adjacent the product and one or more middle layers positioned between the surface layer and the layer adjacent the product, wherein the body comprises 0.05% to 1% by weight of an ultra violet light absorber based on total weight of the body such that the body allows less than 10% transmission of the ultra violet light between 280 nm and 400 nm, and wherein the ultra violet light absorber is incorporated in one or more of the middle layers of the multi-layered laminate body so that any ultra violet absorber concentration at a surface of the multi-layered laminate body is due to migration of the ultra violet absorbers from the one or more middle layers and is less than 0.0033 mg/dm 2 ; and
(b) a dentifrice product housed in the container, the dentifrice product comprising dyes, lakes, or both.

2. The system of claim 1 wherein the body provides less than 10% transmission of the ultra violet light between 280 nm and 380 nm.

3. The system of claim 2 wherein the body provides less than 10% transmission of the ultra violet light between 280 nm and 370 nm.

4. The system of claim 1 wherein the body comprises 0.05% to 0.1wt % of an ultra violet light absorber based on total weight of the body.

5. The system of claim 4 wherein the ultra violet light absorber comprises at least one compound selected from the group consisting of benzophenone, benzotriazole, hydroxyphenyl-triazine, and cerium oxide.

6. The system of claim 1 wherein the refractive index of the dentifrice product is about 1.33 to about 1.47.

7. The system of claim 6 wherein the refractive index of the dentifrice product is about 1.40 to about 1.46.

8. The system of claim 1 wherein the container further comprises a dispensing end.

9. The system of claim 8 wherein the dispensing end is opaque.

10. The system of claim 1 wherein the container has a degree of haze when empty and when filled with the product the container provides clear visibility of the dentifrice product, the degree of haze ranging from 28.3 to 39.3 as measured by ASTM D1003.

11. A dentifrice container and system comprising
(a) a tubular container adapted to house a product, the container comprising a substantially transparent multi-layered laminate body comprising a surface layer, a layer adjacent the product and one or more middle layers positioned between the surface layer and the layer adjacent the product, wherein the body comprises 0.05% to 1% by weight of at least one ultra violet light absorber based on total weight of the body, and wherein the at least one ultra violet light absorber is incorporated in one or more of the middle layers of the multi-layered laminate body so that any ultra violet absorber concentration at a surface of the multi-layered laminate body is due to migration of the ultra violet absorbers from the one or more middle layers and is less than 0.0033 mg/dm 2 ; and
(b) a dentifrice product housed in the container, the dentifrice product comprising dyes, lakes, or both.

12. The system of claim 11 wherein the dentifrice product has a refractive index between 1.33 to about 1.47.

13. The system of claim 12 wherein the refractive index of the dentifrice product is about 1.40 to about 1.46.

14. The system of claim 13 wherein the refractive index of the dentifrice product is about 1.43 to about 1.45.

15. The system of claim 11 wherein the body allows less than 10% transmission of the ultra violet light between 280 nm and 400 nm.

16. The system of claim 15 wherein the body provides less than 10% transmission of the ultra violet light between 280 nm and 380 nm.

17. The system of claim 16 wherein the body provides less than 10% transmission of the ultra violet light between 280 nm and 370 nm.

18. The system of claim 11 wherein the ultra violet light absorber comprises at least one compound selected from the group consisting of benzophenone, benzotriazole, hydroxyphenyl-triazine, and cerium oxide.

19. The system of claim 11 wherein the container has a degree of haze when empty and when filled with the product the container provides clear visibility of the dentifrice product, the degree of haze ranging from 28.3 to 39.3 as measured by ASTM D1003.

20. A dentifrice container and product system comprising
(a) a tubular container adapted to house a product, the container comprising a substantially transparent multi-layered laminate body comprising 5 to 12 layers of flexible materials including a surface layer, a layer adjacent the product and one or more middle layers positioned between the surface layer and the layer adjacent the product, wherein the body comprises 0.05% to 1% by weight of an ultra violet light absorber based on total weight of the body such that the body allows less than 10% transmission of the ultra violet light between 280 nm and 400 nm, and wherein the ultra violet light absorber is incorporated in one or more of the middle layers of the multi-layered laminate body so that any ultra violet absorber concentration at a surface of the multi-layered laminate body is due to migration of the ultra violet absorbers from the one or more middle layers and is less than 0.0033 mg/dm 2 ; and
(b) a dentifrice product housed in the container, the dentifrice product comprising dyes, lakes, or both, wherein the container has a degree of haze when empty and when filled with the product the container provides clear visibility of the dentifrice product, the degree of haze ranging from 28.3 to 39.3 as measured by ASTM D1003.
