REINFORCED CROSS-LAMINATED BULK CONTAINER

摘要

A reinforced cross laminated corrugated paperboard bulk container (10) has an outer component (21) with corrugations running in a first direction, and an inner liner (50) laminated to the outer component, with the liner having corrugations extending perpendicular to the corrugations in the outer component. Reinforcing strands (45,56) are in both the liner and the outer component, extending perpendicular to the respective corrugations thereof. Interlocking top flanges are on the top edges of the outer component, and interlocking bottom flanges are on the bottom edges thereof. The interlocking bottom flanges include a chevron shaped locking slot (43) in one flange and a locking tab (37) on an opposed bottom flange. Folds extend across the bottom flanges to enable them to deflect and slide relative to one another during set up of the container. Vertical scores in the liner are pre-broken prior to laminating it to the outer component.
