Abstract

A chewing gum packaging system comprising a container that contains a volatile-flavor adsorber and at least two flavors of chewing gum. The volatile-flavor adsorber prevents the flavors of the gums from cross-contaminating each other by adsorbing the volatile flavor components from each gum while the gum is stored in the package.

Claims

1. A chewing gum packaging system comprising:

a) a closed container that contains both

b) a volatile flavor adsorber selected from the group consisting of activated carbon, zeolite, vermiculite, sodium bicarbonate and molecular sieves; and

c) at least two pieces of chewing gum, each piece being individually wrapped, wherein at least one piece of said at least two pieces comprises one flavor and wherein at least one other piece of the at least two pieces comprises another, different flavor from the flavor of the at least one piece, and wherein said one flavor of chewing gum comprises a first flavor selected from the group consisting of mint, cinnamon, fruit and bubble gum, and said another different flavor of chewing gum comprises a second flavor selected from the group consisting of mint, cinnamon, fruit and bubble gum;

d) the volatile-flavor adsorber being present in an amount and positioned such that the volatile-flavor adsorber is capable of adsorbing volatile flavor components emitted from each of said pieces of chewing gum before the adsorbed emitted volatile flavor components can contaminate the co-packaged different flavor chewing gum, thereby reducing cross-contamination of the flavors between said one flavor chewing gum, and said different flavor chewing gum in the closed container.

2. The system of claim 1 wherein the container is a tray and further comprises either a plastic, paper, wax-paper or foil overwrap.

3. The system of claim 1 wherein the container is a box.

4. The system of claim 1 wherein the container comprises either a metal, plastic or glass canister.

5. The system of claim 1 wherein the container comprises a plastic bag.

6. The system of claim 5 wherein the bag comprises a strip pouch having a hang tag.

7. The system of claim 1 wherein the adsorber comprises at least one fused unit.

8. The system of claim 7 wherein the fused unit is in a form selected from the group consisting of spheres, pellets, raschig rings, sheets, blocks, wafers, chips and rods.

9. The system of claim 1 wherein the adsorber is in a gas permeable pouch.

10. The system of claim 9 wherein the pouch is made from uncoated spun-bonded polyolefin fibers.

11. The system of claim 1 wherein the adsorber is attached to the container.

12. The system of claim 11 wherein the adsorber comprises at least one fused unit.

13. The system of claim 1 wherein the adsorber is incorporated in the material which forms the container.

14. The system of claim 1 wherein the adsorber is contained in a gas permeable pouch which is attached to the container.

15. The system of claim 1 wherein the volatile-flavor adsorber is activated carbon.

16. The system of claim 1 wherein there are a plurality of individually wrapped pieces of said one flavor of chewing gum and a plurality of individually wrapped pieces of said different flavor of chewing gum, and the plurality of individually wrapped pieces of the chewing gum of said one flavor are packaged together in a first multi-piece package within the container and the plurality of individually wrapped pieces of the chewing gum of said different flavor are packaged together in a second multi-piece package within the container.

17. A chewing gum packaging system comprising:

a) a paperboard tray wrapped in either plastic, paper, wax-paper or foil so as to be closed;

b) a pouch of activated carbon in the closed tray; and

c) at least two pieces of chewing gum in the closed tray each piece being individually wrapped, wherein at least one piece of said at least two pieces comprises one flavor and wherein at least one other piece of the at least two pieces comprises another, different flavor from the flavor of the at least one piece, and wherein said one flavor of chewing gum comprises a first flavor selected from the group consisting of mint, cinnamon, fruit and bubble gum, and said another different flavor of chewing gum comprises a second flavor selected from the group consisting of mint, cinnamon, fruit and bubble gum;

d) the pouch of activated carbon being positioned and containing an amount of activated carbon such that the activated carbon is capable of adsorbing volatile flavor components emitted from each of said pieces of chewing gum before the adsorbed emitted volatile flavor components can contaminate the co-packaged different flavor chewing gum, thereby reducing cross-contamination of flavors between said one flavor chewing gum and said different flavor chewing gum in the wrapped paperboard tray.

18. The system of claim 17 wherein the system contains multiple wrapped pieces of each of three flavors of chewing gum, each wrapped piece of chewing gum being contained within at least one multi-piece package within the paper board tray.

19. The system of claim 17 wherein said one flavor is selected from the group consisting of fruit flavors and said different flavor is selected from the group consisting of mint flavors.

20. A method of packaging chewing gum comprising the steps of packaging both a volatile-flavor adsorber selected from the group consisting of activated carbon, zeolite, vermiculite, sodium bicarbonate and molecular sieves and at least two pieces of individually chewing gum wrapped into a container, and then closing said container containing both said adsorber and said at least two pieces of chewing gum, wherein at least one piece of said at least two pieces comprises one flavor and wherein at least one otherpiece of the at least two pieces comprises another, different flavor from the flavor of the at least one piece, and wherein said one flavor of chewing gum comprises a first flavor selected from the group consisting of mint, cinnamon, fruit and bubble gum, and said another different flavor of chewing gum comprises a second flavor selected from the group consisting of mint, cinnamon, fruit and bubble gum, and wherein the volatile-flavor adsorber is present in an amount and positioned such that the volatile-flavor adsorber is capable of adsorbing volatile flavor components emitted from each of said pieces of chewing gum before the adsorbed emitted volatile flavor components can contaminate the co-packaged different flavor chewing gum, thereby reducing cross-contamination of flavors between said one flavor chewing gum and said different flavor chewing gum in the closed container.

21. A method of packaging chewing gum comprising the steps of:

a) packaging in a paperboard tray

i) at least two pieces of chewing gum, each piece being individually wrapped, wherein at least one piece of said at least two pieces comprises one flavor and wherein at least one other piece of the at least two pieces comprises another, different flavor from the flavor of the at least one piece, and wherein said one flavor of chewing gum comprises a first flavor selected from the group consisting of mint, cinnamon, fruit and bubble gum and said another different flavor of chewing gum comprises a second flavor selected from the group consisting of mint, cinnamon, fruit and bubble gum; and

ii) activated carbon that is contained in a gas-permeable pouch, the activated carbon being present in an amount and the pouch being positioned such that the activated carbon is capable of adsorbing volatile flavor components emitted from each of said pieces of chewing gum before the adsorbed emitted volatile flavor components can contaminate the co-packaged different flavor chewing gum, thereby reducing cross-contaminate flavors between said one flavor chewing gum and said different flavor chewing gum when the tray and chewing gum are closed in a wrapper; and

b) wrapping the tray and said at least two pieces of chewing gum and said pouch containing said activated carbon in either plastic, paper, wax-paper or foil to close the tray.
