Abstract

A product includes a container, and an indicator carried inside the container, and including an air-reactive material and a protective material on the air-reactive material, and having a first visible characteristic with the protective material, and a second visible characteristic when exposed to air without the protective material. A package including the product, and a method for making the package are also disclosed.

First claim

The invention claimed is:

1. A product that includes:
a container; and
an indicator carried inside the container, and including an air-reactive material and a protective material on the air-reactive material, and having a first visible characteristic with the protective material, and a second visible characteristic when exposed to air without the protective material.

2. The product set forth in claim 1 wherein the characteristic is color of the indicator.

3. The product set forth in claim 1 wherein the container is a bottle having a neck, a body and a shoulder connecting the neck to the body, and wherein the indicator is non-removably disposed around an inside surface of the bottle.

4. The product set forth in claim 3 wherein the indicator carries a dissolvable protective material.

5. The product set forth in claim 1 wherein the indicator is adapted, upon contact with air, irreversibly to change a characteristic of the indicator that is visible from outside of the container to indicate to a user that the product has been used.

6. The product set forth in claim 1 wherein the air-reactive material composed of at least one of copper, iron, potassium, sodium, PEN (polyethylene naphthalate), or polycarbonate, and wherein the protective material is composed of at least one of polyacrylic acid, polyacrylamide, xanthan gum, pectin, chitosan derivatives, dextran, carrageenan, guar gum, and/or cellulose ethers, for instance, hydroxypropylmethyl cellulose (HPMC), hydroxypropyl cellulose (HPC), hydroxyethyl cellulose (HEC), or sodium carboxy methyl cellulose (Na-CMC).

7. The product set forth in claim 1 wherein the indicator also includes a carrier material composed of at least one of glass, ceramic, metal, or polymer, and wherein the air-reactive material is composed of at least one of a flavanone, flavanole, dihydrochalcone, chalcone, aurone, or anthocyanidin, and the protective material is composed of at least one of polyacrylic acid, polyacrylamide, xanthan gum, pectin, chitosan derivatives, dextran, carrageenan, guar gum, and/or cellulose ethers, for instance, hydroxypropylmethyl cellulose (HPMC), hydroxypropyl cellulose (HPC), hydroxyethyl cellulose (HEC), or sodium carboxy methyl cellulose (Na-CMC).

8. The product set forth in claim 1 wherein the air-reactive material is composed of at least one of copper, iron, potassium, sodium, PEN (polyethylene naphthalate), or polycarbonate, and the indicator also includes a scavenging material adjacent to the air-reactive material and composed of at least one of iron carbonate, activated carbon, cobalt salt, iron powder, ascorbic acid, photosensitive polymers, or enzymes.

9. The product set forth in claim 1 wherein the container is a bottle having a base, a body extending from the base, a neck, and a shoulder connecting the neck to the body, and the indicator is carried in an upper portion of the container, closer to the neck than to the base.

10. The product set forth in claim 1 wherein the indicator is adapted, upon contact with air, irreversibly to change the characteristic to indicate to a user that the integrity of an as-packaged state of the product has been compromised.

11. The product set forth in claim 1 wherein the indicator includes a substrate and the air-reactive material is carried by the substrate.

12. The product set forth in claim 1 wherein the indicator includes a carrier material with the air-reactive material carried directly on a surface of the carrier material between the carrier material and the protective material and composed of at least one of copper, iron, potassium, sodium, PEN (polyethylene naphthalate), or polycarbonate.

13. The product set forth in claim 12 wherein the air-reactive material is composed of at least one of copper, iron, potassium, sodium, PEN (polyethylene naphthalate), or polycarbonate, and the indicator also includes a scavenging material adjacent to the air-reactive material and composed of at least one of iron carbonate, activated carbon, cobalt salt, iron powder, ascorbic acid, photosensitive polymers, or enzymes.

14. A package including the product set forth in claim 1 , further including a closure coupled to an inside surface of the container.

15. The package set forth in claim 14 , wherein the container is a bottle having a neck, a body and a shoulder connecting the neck to the body, and wherein the indicator is carried by an inside surface of the container neck and is covered by a portion of the closure within the container.

16. The package set forth in claim 14 , wherein the indicator is adapted, upon removal of the closure and of product from the container, irreversibly to change the characteristic to indicate to a user that product has been removed from the container.

17. The package set forth in claim 16 wherein the indicator is covered by the flowable product within the bottle when the bottle rests on its base.

18. The package set forth in claim 16 wherein the protective material is dissolved by the flowable product upon filling the bottle with the product.

19. The package set forth in claim 14 wherein the closure includes an inner skirt having an outer surface in contact with the air-reactive material within the container neck, such that removal of the closure exposes the air-reactive material.

20. The package set forth in claim 14 wherein the protective material is adapted to be removed by the closure.

21. The package set forth in claim 20 wherein at least a portion of the closure is friction-fit within the container neck and within the indicator, such that removal of the closure frictionally pulls the protective material.

22. The package set forth in claim 20 wherein the closure includes an inner skirt coupled to the protective material within the container neck, such that removal of the closure peels the protective material.

23. The package set forth in claim 20 wherein the closure includes an inner skirt having a radially outer projection in contact with the protective material within the container neck, such that removal of the closure scrapes the protective material.

24. The package set forth in claim 20 wherein the closure includes an inner skirt having a radially outer flange disposed axially inward of the protective material within the container neck, such that removal of the closure pulls the protective material away.

25. A product that includes:
a container; and
an indicator carried inside the container, and including an air-reactive material and a protective material on the air-reactive material, and having a first visible characteristic with the protective material, and a second visible characteristic when exposed to air without the protective material; and
a closure, wherein the closure includes a closure member carrying the indicator and having a wedge opening, and a wedge member carried in the wedge opening.

26. A method of producing a package that includes:
(a) positioning an air-reactive indicator inside of a container, wherein the indicator includes a protective material and has a first visible characteristic;
(b) flowing a flowable product into the container; and
(c) assembling a closure to the container,
wherein the protective material is adapted to be removed by the closure such that the indicator becomes exposed to air and, thus, exhibits a second, different visible characteristic that is irreversible to the first characteristic.
