Abstract:
The invention relates to pressed paperboardTcontainers (10), such as disposable paper plates and bowls, having increased strength and rigidity, and the processes used to form such containers by the formation of non- radial pleats (30) at outer regions of the container. The invention also provides pleats (30) about the outer periphery that are non-linear along the length of the pleat (30). Such non-radial and non-linear pleats are formed by forming non-radial and non-linear scores (34) in a blank(36) of paperboard converted into the container geometry.
