a neck portion having an opening;
a body portion continuous to the neck portion and defining a sidewall part; and
a bottom portion continuous to the body portion,

wherein when a direction extending in a horizontal diametrical direction of the opening is referred to as a width direction of the container and a horizontal direction orthogonal to the width direction is referred to as a depth direction of the container, a length in the width direction and a length in the depth direction of a horizontal section of the body portion are different from each other,
wherein the bottom portion includes a projecting portion projecting outward from an outer surface of the bottom portion,
wherein the projecting portion includes a gate portion formed at a tip end of the projecting portion and a protruding portion formed at a position closer to the bottom portion than the gate portion, and
