Disposable food container with a linear sidewall profile and an arcuate outer flange

摘要

The present invention is directed to rigid disposable food containers (10) provided with a relatively steep sidewall with a generally linear profile (20) and an outwardly flared arcuate flange portion (26). The containers (10) are further characterized by a flange outer vertical drop wherein the ratio of the length of the vertical drop to the characteristic diameter of the container (10) is greater than about 0.01. By virtue of unique geometry, the containers (10) of the invention exhibit improved rigidity and/or rim stiffness yet have favorable runnability in pressware manufacturing systems characteristic of plates of lower strength.
