A container is constructed from a synthetic resin. The containers can be efficiently piled or stacked, since ears provided on the container do not prevent piling. The container includes: a bottom part, a drum part provided at the periphery of the bottom part and at least one ear on the drum part and formed by a kerf. The ear is formed unified with the drum part and can stand up from the drum part. A synthetic resin film covers the kerf in a liquid tight manner over at least the ear forming part of the drum part. The container is designed so the ear can stand in use while the container can pile without projection of the ear before using.
