发明名称 Multi-cellular container with cut-score
摘要 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.
