Patent ID: 8276753

Claim:
A packaging structure for containing, transportation, exhibition and dispensing of products comprising: four angular beams arranged in a square or rectangular arrangement; a plurality of angular crossbeams attaching to the four angular beams at each one of its upper and lower ends to form a three-dimensional frame; a plurality of structural corner joints, through which each one of the angular crossbeams are attached to two of the four angular beams, wherein each one of said structural corner joints, is comprised of: an orthogonal square-shaped section with rounded vertex; a pair of fixing tabs of substantially trapezoidal section which are projected perpendicularly from each external side of the orthogonal square-shaped section; a plurality of holes in which are housed fixing means to fix said structural corners to the four angular beams and the plurality of angular crossbeams attached thereto; and a rectangular cavity is provided at the external corner of the orthogonal square-shaped section with rounded vertex between the two fixing tabs of the substantially trapezoidal section; and a plurality of tensing strings comprised in each face of the three-dimensional frame formed by the attachment of the plurality of angular crossbeams and the four angular beams, which are projected defining: external diagonal arrangements, wherein said tensing strings are projected from each one of the corners defined by the attachment of the plurality of angular crossbeams and the four angular beams to the opposite corner on the same face, fixing each one of the ends of said tensing and retaining strings to the rectangular cavity provided in each structural corner joint; and external vertical arrangements wherein said tensing strings are projected from opposite angular crossbeams on one same face, fixing each one of the ends of said tensing strings to each one of said opposite angular crossbeams with fasteners, external horizontal arrangements, wherein said tensing strings are projected from a pair of opposite angular beams in a same face, fixing each one of the ends of said tensing strings to each one of said opposite angular beams; and a plurality of inner tensing strings arrangements at different level, a pair of said tensing strings on each one of its ends attached to a pair of opposite angular beams at the rectangular cavity at same height, so that the strings are crossed each other, providing greater structural stability to the beams and being adapted to provide support for products located directly above the inner tensing strings.
