| 摘要 |
A screw lid (100; 400) for a food container (102; 402) is disclosed. The screw lid (100; 400) comprising a series of radially extending asymmetric protrusions (116;416) arranged around a peripheral edge region (110; 410), wherein the asymmetric protrusions (116; 416) facilitate enhanced gripping when the lid (100; 400) is turned in an opening direction (106) as compared to the gripping facilitated when the lid (100; 400) is turned in a closing direction (104). |

1. A screw lid for a food container and comprising:
a series of radially extending asymmetric protrusions arranged around a peripheral edge region, the asymmetric protrusions being configured to facilitate enhanced gripping when the lid is turned in an opening direction as compared to the gripping facilitated when the lid is turned in a closing direction, and each asymmetric protrusion having a maximum radial extent that is curved to smooth an outer surface of the screw lid. |
