Damage-resistant packaging box for shipping planar articles

A damage-resistant packaging box for shipping planar articles, the damage-resistant packaging box comprising:

• a base box portion, the base box portion comprising opposed side wall attachment portions, opposed top flap attachment portions, and a plurality of outwardly extending box bottom corner extensions, the plurality of posterior box corner extensions extending obliquely and outwardly relative to the opposed side wall attachment portions;
• opposed side wall flap portions extending from the opposed side wall attachment portions, the opposed side wall flap portions each comprising an outer side flap terminal edge, opposed side flap edges, opposed oblique side flap edges, a side flap inner first fold line, and a side flap outer second fold line, the opposed oblique side flap edges extending obliquely relative to the first fold lines and the opposed side flap edges;
• and
• opposed top flap portions, the top flap portions extending from the opposed top flap attachment portions, the opposed top flap portions each comprising an outer top flap terminal edge, opposed inner top flap side edges, opposed oblique top flap edges, opposed outer top flap side edges, a top flap inner first fold line and a top flap outer second fold line, the opposed oblique top flap edges extending obliquely relative to the opposed inner top flap side edges and the opposed outer top flap side edges;
• the opposed side wall flap portions being firstly foldable along the opposed inner first fold lines and secondly foldable along opposed outer second fold lines thereby defining a first pair of opposed box side walls and the opposed side wall flap portions thereby covering first opposed portions of an article received in anterior adjacency to the base box portion;
• the opposed top flap portions being firstly foldable along the top flap inner first fold lines and secondly foldable along the top flap outer second fold lines thereby defining a second pair opposed box side walls and the opposed top flap portions thereby covering second opposed portions of the article received in anterior adjacency to the base box portion thereby forming the damage-resistant packaging box;
• the damage-resistant packaging box each side wall of the first pair of opposed side walls comprising opposed side wall extension portions, the opposed outer top flap edges and the opposed oblique top flap edges together providing a plurality of anterior corner extensions terminating centrally relative to the longitudinally opposed box side walls at the laterally opposed inner top flap side edges thereby providing a butterfly shaped configuration of the damage-resistant packaging box when viewed in plan;
• the posterior box corner extensions, the anterior box corner extensions, and the side wall extension portions extending orthogonally outwardly relative to the first pair of opposed side walls thereby providing opposed pairs of three-sided, box-reinforcing corner extension features such that the posterior box corner extensions extend in spaced parallel relation to the anterior box corner extensions, and the opposed side wall extension portions orthogonally interconnect the posterior box corner extensions to the anterior box corner extensions.

A damage-resistant packaging box, the damage-resistant packaging box comprising:

• a primary article-containing package portion, the primary article-containing packaging portion comprising a package length, a package width, a package depth, interior package surfacing, exterior package surfacing, and a plurality of package corners, the package length and the package width being greater than the package depth;
• a plurality of three-sided, box-reinforcing corner extension features extending orthogonally outwardly from a first pair of opposed box side walls of the article-containing package at the external package surfacing for providing package-strengthening structure at the plurality of package corners;
• and
• a package closure mechanism, the package closure mechanism for enabling a user to insert an article into the primary article-containing package portion and for enabling the user to close the primary article-containing package portion for article shipment;
• each three-sided, box-reinforcing corner extension feature being characterized by a posterior box corner extension, an anterior box corner extension, and a side wall extension portion, the posterior box corner extension extending in spaced parallel relation to the anterior box corner extension, the side wall extension portion orthogonally interconnecting the posterior box corner extension to the anterior box corner extension the anterior box corner extensions at each of the first pair of opposed box side walls terminating obliquely and centrally relative to one another so as to provide a butterfly shaped configuration of the damage-resistant packaging box when viewed in plan.
