A molded plastic container is shaped so as to resist deformation as a result of compressive forces that may be applied by the consumer during use. The container includes a pair of recessed grip portions that are molded into forward and rearward sides of the container and an outer handle portion. Reinforcing ribs are integrally molded into the forward and rearward sidewalls of the container in areas that are substantially adjacent to the recessed grip portions in order to provide additional crush resistance as the container is squeezed. Additionally, a torsional reinforcement rib is integrated into an upper side portion of the container in order to resist deformation of the container and the pouring opening of the container during pouring. The torsional reinforcement rib is integral with the two reinforcing ribs, which provides additional strength and pouring stability to the container.
