A multi-cellular polypropylene container with a cut-scored region connecting the cells of the container is described. By varying the cut-score depths depending on the orientation of the plastic material, greater consistency in the tearability of the individual cells is achieved. One or more star-cut
A multi-cellular polypropylene container with a cut-scored region connecting the cells of the container is described. By varying the cut-score depths depending on the orientation of the plastic material, greater consistency in the tearability of the individual cells is achieved. One or more star-cut patterns may be provided between the cells. The star-cut patterns have curved edges that lead to the separation region. The curved edges provide a generally smooth surface that does not cut or snag the user.

What is claimed: 1. A method of manufacturing a multi-cellular container from a plastic sheet, comprising: forming a plurality of cells connected together by a separation region, wherein an individual cell may be removed by tearing the separation region between the individual cell and the plurality
What is claimed: 1. A method of manufacturing a multi-cellular container from a plastic sheet, comprising: forming a plurality of cells connected together by a separation region, wherein an individual cell may be removed by tearing the separation region between the individual cell and the plurality of cells; and providing cut-scores between the plurality of cells, wherein the cut-scores parallel to an index direction of the plastic sheet are deeper than the cut-scores perpendicular to the index direction. 2. The method of manufacturing a multi-cellular container according to claim 1, further comprising forming star-cut patterns between the plurality of cells. 3. The method of manufacturing a multi-cellular container according to claim 2, further comprising forming the star-cut patterns with curved and generally smooth edges that lead to the separation region. 4. The method of manufacturing a multi-cellular container according to claim 3, wherein the curved and generally smooth edges provides corners for the cells having a radius. 5. The method of manufacturing a multi-cellular container according to claim 1, further comprising forming star-cut patterns between the plurality of cells without sharp corners. 6. The method of manufacturing a multi-cellular container according to claim 1, wherein the cut-scores and a star-cut pattern between the plurality of cells are cut before a perimeter of the multi-cellular container is cut. 7. The method of manufacturing a multi-cellular container according to claim 1, wherein the cut-scores and a star-cut pattern between the plurality of cells are cut by one trim press and a perimeter of the multi-cellular container is cut by another trim press. 8. The method of manufacturing a multi-cellular container according to claim 1, wherein the cut-scores and a star-cut pattern between the plurality of cells are cut in one step and a perimeter of the multi-cellular container is cut in another step. 9. The method of manufacturing a multi-cellular container according to claim 1, wherein the cut scores alternate with a cut-through. 10. The method of manufacturing a multi-cellular container according to claim 1, wherein the cut-scores between the individual cells includes a cut-through at the beginning of the cut-scores. 11. The method of manufacturing a multi-cellular container according to claim 1, further comprising forming the multi-cellular container with four cells. 12. The method of manufacturing a multi-cellular container according to claim 1, wherein an individual cell removed from the plurality of cells has a perimeter formed from the separation region, wherein the perimeter has a generally smooth edge. 13. A method of manufacturing a multi-cellular container, comprising: forming a plurality of cells from a sheet of plastic, wherein the cells are connected together by a separation region, wherein an individual cell may be removed by tearing the separation region between the individual cell and the plurality of cells; providing cut-scores in the separation region, wherein the cut-scores parallel to an index direction of the plastic material are deeper than the cut scores perpendicular to the index direction. 14. The method of manufacturing a multi-cellular container according to claim 13, further comprising thermoforming the plurality of cells from a sheet of polypropylene, wherein the cells are depressions having a bottom and sides, the sides are angled or curved relative to the bottom, the sides transition into a generally planar boundary that forms a rim for each cell, and the boundary comprises the separation region. 15. The method of manufacturing a multi-cellular container according to claim 13, further comprising forming alternating cut-throughs with the cut-scores in the separation region. 16. A method of manufacturing a multi-cellular container, comprising: forming a plurality of cells from a sheet of plastic, wherein the cells are connected together by a separation region, wherein an individual cell may be removed by tearing the separation region between the individual cell and the plurality of cells; cutting cut-scores in the separation region with one trim press, wherein the cut-scores parallel to an index direction of the sheet of plastic are deeper than the cut-scores perpendicular to the index direction; cutting a star-cut pattern between the plurality of cells with the one trim press; and cutting a perimeter of the multi-cellular container with another trim press. 17. The method of manufacturing a multi-cellular container according to claim 16, wherein the cutting of the cut-scores and the cutting of the star-cut pattern between the plurality of cells occurs in one step and the cutting of the perimeter of the multi-cellular container occurs in another step. 18. The method of manufacturing a multi-cellular container according to claim 16, further comprising using a vertical trim press to cut the star-cut pattern, the cut scores, and an inner portion of a curved edge that forms rounded corners for the cells, and further comprising using a horizontal trim press to cut an outer portion of the curved edge and outer edges of the multi-cellular container.
