ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to containers and more particularly to polygon-shaped containers, such as Gaylord containers, made from normally rigid boards, such as Kraft linerboards laminated together up to approximately 400 thousands of an inch thick and having a capacity of up to 1,000 pounds or more.
Gaylord containers have been known and used for years to ship large quantities of material, 1,000 pounds or more. The Gaylord containers in the past have been made from corrugated paperboard, or cardboard. Corrugated cardboard containers are relatively weak and can be easily punched through by sharp objects.
If polygon-shaped containers, including Gaylord containers, could be made from normally rigid boards, such as several sheets of Kraft linerboard laminated together to a thickness of approximately 400 thousands of an inch, the containers would be such stronger and could not be punched through by sharp objects.
The problem with using the normally rigid boards, such as laminated Kraft linerboard mentioned above, is how do you bend such a board to make the polygon-shaped container without breaking the board at a bend.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a plastic, flexible connecting member to connect a plurality of normally rigid board members together to form a desired polygon-shaped container and also to enable the polygon-shaped container to be shipped flat to a customer.
Another object of the present invention is to provide a container made from solid, normally rigid boards having a decigon configuration.
Another object of the present invention is to provide a container made from solid, normally rigid boards having a rectangular configuration.
A feature of the present invention is the provision of a polygon-shaped container comprising a plurality of normally rigid boards providing sides of a polygon-shaped container having a predetermined polygon configuration; a plurality of connecting members connecting adjacent edges of the plurality of normally rigid boards together, each of the plurality of connecting members having sufficient strength to maintain the polygon-shaped container in the predetermined polygon configuration and yet sufficient flexibility to enable the plurality of normally rigid boards to be shipped flat to a user who will form the polygon-shaped container into the predetermined polygon configuration; a first means to close a bottom of the polygon-shaped container; and a second means to close a top of the polygon-shaped container after being filled.
