Abstract
A container having a curved bottom and base cup which allows the container to stand upright. The container and base cup are fitted together by a mechanical engagement having portions on the container and base cup. The mechanical engagement of the container is disposed within the bottom cone of the container. The mechanical engagement of the base cup is cantilevered from the bottom of the base cup. Such disposition reduces stress at the interface between the side wall of the container and edge of the base, providing for a smoother transition and better appearance. Also, this disposition provides resistance to separation of the container and base cup during drop impact. The bottom of the container may be curved and have a well therein for receiving the contents of the container and a dip tube.
