Abstract

A carrier and method of manufacture for a carrier that results in a package of containers includes a plastic sheet having an array of container apertures and a portion having a printed matte finish where the printed matte finish includes a lower coefficient of friction relative to a container than a remaining surface of the plastic sheet. A plurality of containers are each positioned within an aperture of the array so that the printed matte finish of the plastic sheet is positioned along an inner portion of the package and the remaining surface of the plastic sheet is positioned along an outer portion of the package.

First claim

The invention claimed is:

1. A carrier for carrying an array of containers comprising:
a plastic sheet having a generally smooth surface and a plurality of container apertures formed therein and arranged in adjacent rows and adjacent ranks, wherein the plastic sheet is generally transparent and includes a printed matte finish formed of a printed ink, the printed matte finish on the plastic sheet between the adjacent rows and the adjacent ranks of the container apertures, wherein the printed matte finish is configured to contact the containers and has a roughness value Ra of at least 100 microinches.

2. The carrier of claim 1 wherein the printed matte finish has a different coefficient of friction relative to sidewalls of the containers than the plastic sheet.

3. The carrier of claim 1 wherein the printed matte finish has a roughness value Ra in a range of 100-125 microinches.

4. The carrier of claim 1 wherein the printed matte finish comprises a UV-cured flexography ink.

5. The carrier of claim 1 further comprising a corona pretreatment applied to the plastic sheet between the plastic sheet and the printed ink.

6. A method for manufacturing the carrier according to claim 1 and having an array of apertures each for receiving a container, the method comprising:
feeding a flexible plastic sheet across a roller;
printing the printed matte finish to the plastic sheet;
forming the plastic sheet into the container carrier so that the printed matte finish is positioned in a desired location.

7. The method of claim 6 additionally comprising:
corona treating of the plastic sheet in preparation for said printing of the matte finish.

8. The method of claim 7 wherein the corona treating comprises application of a minimum of 38 dynes/cm 2 .

9. The method of claim 6 wherein the matte finish is printed via flexography.

10. The method of claim 9 wherein the flexography comprises UV-curable flexography.

11. The method of claim 6 wherein the printed matte finish is aligned in a plurality of longitudinal strips along the plastic sheet.

12. The method of claim 6 wherein the printed matte finish is positioned between outer edges of the plurality of container apertures.

13. The method of claim 6 wherein the printed matte finish has a different coefficient of friction relative to a sidewall of the container than the plastic sheet.

14. A package of containers comprising:
a sheet having a plurality of container apertures arranged in adjacent rows and ranks;
a portion of the sheet having a corona pretreatment and a printed matte finish of printed ink on and over the corona pretreatment; and
a plurality of containers positioned within respective container apertures so that the printed matte finish contacts at least a portion of each container of the plurality of containers, wherein the printed matte finish is between the adjacent rows and the ranks of the container apertures, wherein the printed matte finish has a roughness value Ra of at least 100 microinches.

15. The package of containers of claim 14 wherein the printed matte finish has a roughness value Ra in a range of 100-125 microinches.

16. The package of containers of claim 14 wherein the portion of the sheet having a printed matte finish is aligned in longitudinal strips along the plastic sheet.

17. The package of containers of claim 14 wherein the portion of the sheet having a printed matte finish is positioned between outer edges of the plurality of container apertures.
