Packaging container, and method and apparatus for making same
Abstract:
A new and improved packaging container, and a method and apparatus for fabricating the same, comprises a laminated structure comprising a plurality of plies formed from suitable paper or similar materials. The plurality of plies, having a predetermined width dimension, are bonded together in a substantially flattened state by glue which is applied in predetermined, axially extending, laterally staggered patterns. Subsequently, the substantially flat, laminated structure is longitudinally scored or embossed at predetermined lateral or transverse positions so as to effectively predispose, and thereby facilitate, for example, the upward folding of oppositely disposed side members of the laminated structure with respect to a central member of the laminated structure whereby the resulting packaging container not only has a desirable substantially U-shaped cross-sectional configuration, but in addition, has optimized flexural beam strength characteristics within its corner regions due to the fact that the oppositely disposed corner regions preferably comprise the same number of multiple plies as the side wall and bottom wall members of the packaging container.
