A reinforced cross laminated corrugated paperboard bulk container has an outer component with corrugations running in a first direction, and an inner liner laminated to the outer component, with the liner having corrugations extending perpendicular to the corrugations in the outer component. Reinforcing strands 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 in one flange and a locking tab 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.

Reinforced cross-laminated bulk container

A reinforced cross laminated corrugated paperboard bulk container has an outer component and an inner liner laminated to the outer component with the liner having corrugations extending perpendicular to the corrugations in the outer component. The bottom edges of the sidewalls include a first pair of flaps and a second pair of flaps each of which foldably extend outwardly therefrom and wherein each of the second pair of flaps having a pair of spaced apart triangularly shaped slots formed therein and wherein each of the first pair of flaps includes a pair of locking tabs formed on opposed end of the respective first pair of flaps which are engaged with the slots on the second pair of the flaps to securely close the bottom of the container. Vertical scores in the liner are pre-broken prior to laminating it to the outer component.

The present invention includes a blank and container wherein the container includes truncated corner panels and the container is configured to attach or otherwise sit upon a supporting structure, such as, without limitation, a pallet. The truncated corners of the container coupled with the non-truncated corners of the supporting structure cause the corners of the supporting structure to extend beyond the perimeter of the container. Corner tabs having hazard-warning indicia upon an upper surface are configured to extend over the exposed supporting structure corners. Consequently, attention is drawn to the extended supporting structure corners thereby helping to prevent tripping over the pallet corners The indicia may be brightly colored stripes, solid fields or any other indicia. The indicia may be printed and formed in same process as printing labels on the container, thereby requiring no additional manufacturing steps.

Container with hazard warning feature

The present invention includes a blank and a container constructed from containerboard material cut and scored to form an inner and an outer housing. The outer housing includes opposing side and end walls that are hingedly attached to a plurality of bottom panels that form a container bottom. The bottom panels include a hopper bore defined therethrough. An inner housing includes an interior upper region and an interior lower region. At least a portion of the interior upper region is substantially rigidly attached to an inner surface of the outer housing. The interior lower region is configured to form a plurality of inwardly angled interior panels that are angled substantially in the direction of the hopper bore. A removable closure panel is configured to close or otherwise substantially selectively seal the hopper bore.

Hopper box

A bulk bin container and blank is provided having container walls formed of triple wall paperboard material. At least one tear tape is attached laterally to the inside surface of the triple wall material. The tear tape includes first and second ends, with the tear tape itself defining upper and lower container portions. An opening mechanism is provided at the tear tape first end for starting the tape. During use, an operator grasps the opening mechanism and pulls outward and upward on the tear tape, thereby stepping through the triple wall material and separating the upper container portion from the lower container portion.
