Abstract

A product includes a container, and an indicator that is carried inside the container and that exhibits a first visible characteristic, and a second, different visible characteristic when exposed to air.

First claim

The invention claimed is:

1. A package that includes:
a container, wherein the container is a bottle having a neck, a body and a shoulder connecting the neck to the body,
a product dispensably disposed within the container,
a closure carried by the container, and
an indicator within the container,
the indicator being 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 package has been used
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 package has been compromised, 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.

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

3. The package set forth in claim 1 wherein the indicator initially has a protective material that is dissolved by the product upon filling the container with the product.

4. The package set forth in claim 1 wherein the indicator is composed of an air-reactive material.

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

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

7. The package set forth in claim 1 wherein the indicator includes an air-reactive material 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.

8. The package 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.

9. The package set forth in claim 1 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.

10. The package set forth in claim 1 wherein the indicator includes a protective material adapted to be removed by the closure.

11. The package set forth in claim 10 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.

12. The package set forth in claim 10 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.

13. The package set forth in claim 10 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.

14. The package set forth in claim 10 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.

15. The package set forth in claim 1 wherein the indicator includes an air-reactive material, and 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.

16. A product that include:
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 firt visible characteristic with the protective material, and a second visible characteristic when exposed to air without the protective material, wherein the container is a bottle that includes a base, a body extending from the base, a shoulder extending from the body, and a neck, and indicator is carried in an upper portion of the container, closer to the neck than to the base, wherein the air-reactive material is composed of at least one of copper, iron, potassium, sodium, PEN (polyethylene naphthalate), or polycarbonate, and the protective material is composed of at least one of at least one of polyacrylic acid, polyacrylamide, xanthan gum, pectin, chitosan derivatives, dextran, carrageenan, guar gum, and/or cellulose ethers including hydroxypropylmethyl cellulose (HPMC), hydroxypropyl cellulose (HPC), hydroxyethyl cellulose (HEC), or sodium carboxy methyl cellulose (Na-CMC).

17. 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, 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.

18. 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 flowing step (b) includes covering the indicator with the flowable product to dissolve the protective material.

19. The method set forth in claim 18 wherein the positioning step (a) includes assembling the indicator to an inside surface of the container.

20. A method of using a package produced by a method of producing the package that includes (a) positiong 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
