Container having oxygen scavenging system
View Patent ↗A polyethylene terephthalate container having a hydrogen generator and catalyst disposed or otherwise incorporated in components of the container, including the closure, closure insert, label, label glue, and/or any other portions of the final container assembly. In addition, the catalyst and the hydrogen generator can both be located in the same component. Methods for dispersing the hydrogen generator and catalyst in the container wall without affecting clarity are provided.
1. A container having a neck, a shoulder portion, a base portion, and a sidewall portion interconnecting the shoulder portion and the base portion to form a volume for receiving a commodity, the container comprising:
a hydrogen generator generating molecular hydrogen, the hydrogen generator at a first location of the container; and
a catalyst catalyzing a chemical reaction between the hydrogen and oxygen, the catalyst at a second location of the container;
wherein the first location is chosen from the group consisting of a label affixed to the sidewall portion, a label adhesive used to affix the label to the sidewall portion, and ink used in printing on the container.
2. The container according to claim 1 wherein the second location is chosen from the group consisting of the label affixed to the sidewall portion, the label adhesive used to affix the label to the sidewall portion, and the ink used in printing on the container.
3. The container according to claim 1 wherein the first location is the same as the second location.
4. The container of claim 1 , wherein the hydrogen generator and the catalyst are a combined product that includes a compatibilizer.
5. The container of claim 4 , wherein the compatibilizer is 12-aminododecanoic acid.
6. A container having a neck, a shoulder portion, a base portion, and a sidewall portion interconnecting the shoulder portion and the base portion to form a volume for receiving a commodity, the container comprising:
a hydrogen generator generating molecular hydrogen that is included with at least one of a label affixed to the sidewall portion, a label adhesive configured to affix the label to the sidewall portion, and ink of a printing on the container; and
a catalyst catalyzing a chemical reaction between the hydrogen and oxygen, the catalyst included with at least one of the label, the adhesive, and the ink;
wherein the label includes a hydrogen-reflective layer.
7. The container of claim 6 , wherein the hydrogen generator and the catalyst are at a common location.
8. The container of claim 6 , wherein the hydrogen generator is dissolved in a solvent.
9. The container of claim 6 , wherein the container is formed from an extruded polymer preform.
10. The container of claim 6 , wherein the hydrogen generator and the catalyst are a combined product that includes a compatibilizer.
11. The container of claim 10 , wherein the compatibilizer is 12-aminododecanoic acid.
12. A container having a neck, a shoulder portion, a base portion, and a sidewall portion interconnecting the shoulder portion and the base portion to form a volume for receiving a commodity, the container comprising:
a label affixed to an outer surface of the container with an adhesive;
a hydrogen generator generating molecular hydrogen, the hydrogen generator at least one of on or in the label; and
a catalyst catalyzing a chemical reaction between the hydrogen and oxygen, the catalyst at least one of on or in the label.
13. The container of claim 12 , the label further comprising a hydrogen-reflective layer.
14. The container of claim 12 , wherein the label is affixed to the outer surface of the container with an adhesive, the adhesive including both the hydrogen generator and the catalyst.
15. The container of claim 12 , wherein the container further includes an ink printing on at least one of the container and the label, the ink printing includes at least one of the hydrogen generator and the catalyst.
16. The container of claim 12 , wherein the hydrogen generator is further included on or in at least one of the neck and the base portion; and
wherein the catalyst is further included on or in at least one of the neck and the base portion.
17. A container having a neck, a shoulder portion, a base portion, and a sidewall portion interconnecting the shoulder portion and the base portion to form a volume for receiving a commodity, the container comprising:
an ink printing;
a hydrogen generator generating molecular hydrogen, the hydrogen generator included with the ink printing; and
a catalyst catalyzing a chemical reaction between the hydrogen and oxygen, the catalyst included with the ink printing.
18. The container of claim 17 , wherein the ink printing is at least one of directly on the container or on a label affixed to an outer surface of the container.
19. The container of claim 17 , further comprising a label affixed to an outer surface of the container with an adhesive, at least one of the hydrogen generator and the catalyst are included with the label.
20. The container of claim 19 , wherein at least one of the hydrogen generator and the catalyst are included with the adhesive.
