PROBLEM TO BE SOLVED: To eliminate bulkiness when being stacked up, to make taking-out from the state of being stacked up easy, and to provide a satisfactory condition without disturbing balance at a mass production line by a method wherein hollows to which fingertips can be inserted when being stacked up are formed at a gripping rim. SOLUTION: For a packing member 10, two hollows 3 and 3 to which fingertips can be inserted are provided at opposite positions on a gripping rim 2 formed around a main body part 1 in the diameter larger than that of the main body part, and a housing hollow 4 is provided at the inside of the main body part 1. In the case where two or more packing members 10 are stacked up, the upper packing member 10 can be taken out easily while being lifted up with fingertips inserted respectively into the hollows 3 and 3 on the gripping rim 2 of the lower packing member 10 and made to catch at the surface of the lower edge of the upper packing member 10. Further, the greater part of the main body part of the upper packing member 10 is put into the housing hollow 4 of the lower packing member 10 so that bulkiness can be eliminated. |
