Abstract
A first and second blank of corrugated paperboard scored to define wall panels that receive a reinforced wall panel assembly having a central pad with opposing vertical members and opposing horizontal members and a pair of U-shaped channels each attached in overlying relation with the pad, the vertical members and a respective horizontal member to secure the wall panel assembly together. A method of making a bulk materials container is disclosed.
Claims21
A bulk materials container, comprising:
- a first wall-forming blank of corrugated paperboard scored to provide a plurality of first main panels foldably joined together, each of the plurality of first main panels defining a side wall and having a first closure flap foldably joined to a first edge thereof;
- a plurality of reinforcement panel assemblies, each of the plurality of reinforcement panel assemblies mounted to a respective side wall of the first main panel of the first wall-forming blank of corrugated paperboard, each of the plurality of reinforcement panel assemblies comprising:
- a pad having opposing planar sides with opposing first side edges and opposing second side edges;
- a pair of first support members each disposed adjacent a respective one of the opposing first side edges of the pad;
- a pair of second support members each disposed adjacent a respective one of the opposing second side edges of the pad;
- and
- a pair of liner sheets,
- each of the pair of liner sheets folded to define a U-shaped channel having opposing interior surfaces that attach to a respective one of the opposing planar sides of the pad in overlying relation to the pad, the pair of first support members, and a respective one of the pair of second support members on the respective one of the opposing second side edges of the pad,
- each of the pair of liner sheets extending a length substantially between respective outer edges of the pair of first support members and extending to a distal edge remote from an edge of the respective one of the pair of second support members, configured to secure the pair of first support members and the respective one of the pair of second support members to the pad;
- and
- a second wall-forming blank of corrugated paperboard scored to provide a plurality of second main panels foldably joined together, each of the plurality of second main panels having a second closure flap foldably joined to an edge portion thereof, the second wall-forming blank laminated in overlying relation with a respective one of the plurality of second main panels attached to a respective one of the plurality of reinforcement panel assemblies,
- whereby the first wall-forming blank and the second wall-forming blank, being folded on the respective scores, forms the side walls of the bulk materials container and the respective one of the first closure flap and the second closure flap, being folded on the respective scores, close an end opening thereof.
