ABSTRACT:
A container is disclosed, generally having an open top defined by an annular rim, a base, and a sidewall extending between the top and the base. The sidewall has two arcuately formed longitudinal recesses, an annular rib, an annular shoulder located between the longitudinal recesses and the base, and a lower portion extending between the annular shoulder and the base. The annular shoulder is characterized by two arched portions aligned with the longitudinal recesses, and the lower portion has two beveled portions aligned with the longitudinal recesses. This container is more ergonomic, and has greater sidewall strength and rigidity, than existing containers.
