This study aims to investigate the mechanical response of bucket with a handle and bucket without a handle in different dropping conditions. The finite element models of the two kinds of buckets with fluid were established. And the stress fields of the buckets were obtained at different dropping heights. The easily leak location of the bucket with a handle was located on its top, and that of the bucket without a handle was located on the contact point between the bucket and the ground; the resistance to dropping impact of the bucket without a handle was superior to that of the bucket with a handle. In the design process of the opening plastic bucket, the size and the shape of the bucket top should be paid more attention to so as to reduce the stress concentration caused by the fluid impact.
