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 first main panel having a closure flap foldably joined to a first edge thereof;
- a plurality of reinforcement panel assemblies, each attached to a respective main panel of the first wall-forming blank of corrugated paperboard, each of the 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 folded to define a U-shaped channel having opposing interior surfaces that each attaches to a respective one of the opposing planar sides of the pad in overlying relation to the pad, the first support members and a respective one of the second support members on a respective one of the second side edges of the pad,
- the liner sheet extending a length substantially between respective outer edges of the first support members and extending to a distal edge remote from an edge of the respective second support member, for securing the pair of first support members and the respective one of the 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 second main panel having a closure flap foldably joined to an edge portion thereof, the second wall forming blank laminated in overlying relation with a respective second main panel attached to a respective one of the reinforcement panel assemblies,
- whereby the wall-forming blanks, being folded on the respective scores, forms side walls of the bulk materials container and the respective closure flaps, being folded on the respective scores, close an end opening thereof.
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 first main panel having a first closure flap foldably joined to a first edge and a second closure flap foldably joined to a second edge opposing the first edge;
- a plurality of reinforcement panel assemblies, each attached to a respective main panel of the first wall-forming blank of corrugated paperboard, each of the 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 folded to define a U-shaped channel that attaches in overlying relation to the pad, the first support members and a respective one of the second support members on a respective one of the second side edges of the pad,
- the liner sheet extending a length substantially between respective outer edges of the first support members and extending to a distal width edge distal from the second side edge and overlying an edge of the respective second support member adjacent the respective second side edge of the pad, for securing the pair of first support members and the respective one of the 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 second main panel having a first closure flap foldably joined to first edge and a second closure flap foldably joined to a second edge opposing the first edge, the second wall forming blank laminated in overlying relation with a respective second main panel attached to a respective one of the reinforcement panel assemblies,
- whereby the wall-forming blanks, being folded on the respective scores, forms side walls of the bulk materials container and the respective first and second closure flaps, being folded on the respective scores, close a respective end opening thereof.
A method of manufacturing a bulk materials container, comprising the steps of:
- (a) making a plurality of reinforcement panel assemblies, comprising the steps of:
- i) disposing a pair of first support members adjacent a respective one of a pair of opposing first side edges of a pad having opposing planar surfaces;
- ii) disposing a pair of second support members adjacent a respective one of a pair of opposing second side edges of the pad;
- iii) securing the first support members and a respective one of the second support members with a respective one of a pair of U-shaped channels that each attaches in overlying relation to the pad, the first support members and a respective one of the second support members on a respective one of the second side edges of the pad, the U-shaped channel extending a length substantially between respective outer edges of the first support members and extending to a distal width edge remote from and overlapping an edge of the respective second support member, for securing the pair of first support members and the respective one of the second support members to the pad;
- (b) scoring a first wall-forming blank of corrugated paperboard to define a plurality of first main panels foldably joined together;
- (c) attaching one of the reinforcement panel assemblies to a respective main panel of the first wall-forming blank of corrugated paperboard;
- (d) scoring a second wall-forming blank of corrugated paperboard to define a plurality of second main panels foldably joined together;
- and
- (e) attaching a respective second main panel to a respective one of the reinforcement panel assemblies,
- whereby the first and second wall-forming blanks, being folded on the respective scores, forms side walls of the bulk materials container.
