PROBLEM TO BE SOLVED: To provide a lid that can reduce materials while being capable of securing required strength.SOLUTION: A lid includes a plate-like lid body 30 formed of a foamed synthetic resin, freely detachably configured at an opening of a container body, and formed into a substantially-rectangular shape. A frame-like protrusion ridge T is formed over the entire area of the outer peripheral part of the upper surface of the lid body 30. Each of first cutout parts S1 is formed at both ends in the side direction of each of two opposite sides of the protrusion ridge T while having a predetermined length so as to allow each of bands which is wound around the container body and the lid body 30 in order to fix both of them to each other to intrude therein. A second cutout part S2 having a predetermined length longer than the predetermined length of the first cutout part S1 is formed between the first cutout parts S1, S1 at both ends in the side direction of each of the two sides. |
