Abstract
A seal member has a first seal layer which is opposite a container main body; and a second seal layer which is opposite a cap member and the compression slip resistance ρ [N] of the first seal layer, the compression rate k [%] of the first seal layer, the thickness T1 [mm] of the first seal layer, the compression residual strain ε1[%] of the first seal layer, the thickness T2 [mm] of the second seal layer, the compression residual strain ε2[%] of the second seal layer, the thickness Tn [mm] of the seal layer other than the first seal layer and the second seal layer and the compression residual strain εn [%] of the seal layer other than the first seal layer and the second seal layer satisfy 0<ρ/k<0.3 and 0.04<T2ε2/(T1ε1+T2ε2+ . . . Tnεn)<0.48.
