A packing case includes a body part having a quadrangular section and a bottom part for closing a lower opening of the body part. The body part includes first to fourth side plates forming sides of the quadrangle, and first to fourth bottom plate pieces are respectively connected to lower end parts of the first to fourth side plates via fold lines. The bottom part is configured by allowing the first to fourth bottom plate pieces folded to a side of the lower opening along the fold lines to be integrally engaged with one another and to be connected with one another, and at least one support piece, which is able to assemble support body that support an object to be packed, is connected to at least one of the first to fourth bottom plate pieces.

A spliced storage box and a splicing structure between adjacent side panels of the spliced storage box are provided. The splicing structure comprises two side panels, a post, and a pressing strip. A side of the post comprises a notch, each corner of two sides of the notch comprises a first positioning edge and a second positioning edge intersecting the first positioning edge. Side edges, which are adjacent to each other, of the two side panels each bend and define a first abutting edge and a second abutting edge. The first abutting edge is disposed at an outer end of a respective one of the two side panels, and the first abutting edge and the second abutting edge respectively abut the first positioning edge and the second positioning edge. The pressing strip is connected to the post and is pressed to the first abutting edges of the two side panels.

A blank assembly for forming a container includes a body blank that includes a bottom panel and two opposing side panels. The side panels are configured to at least partially form two opposing side walls of the container. The blank assembly also includes at least two end blanks. Each end blank is configured to form at least a portion of an end wall of the container. Each end blank includes a first inner corner panel, a first inner end panel, a first reinforcement panel, a second reinforcement panel, and a second inner end panel coupled together in series along preformed, parallel fold lines. The first inner corner panel is configured to extend obliquely between a side wall and an end wall. The first reinforcement panel is configured to extend from the first inner end panel inwardly towards an interior cavity of the container.

A packaging box, cutouts, method and device for producing corrugated cardboard boxes comprising walls, a base (6) and a cover (7), the inner face of the base being provided with at least two recesses (33) and the cover comprising at least two tabs (38) adhered to the upper face thereof, directly above the recesses of complementary shape. The recesses and/or the tabs are situated fully inside the corresponding face or faces (31, 32).

The present invention relates to a reinforcement system and method for supporting stacked containers or boxes, without resulting in damage to the contents and the containers themselves. The system comprises at least one pillar element (1) and at least one end shoulder element (2), where the at least one pillar element (1) is arranged in at least one corner of the stack formed by the containers, and where the at least one end shoulder element (2) is arranged at the lower and upper ends of each of the vertical corners of containers stack, where the pillar element (1) has a smaller dimension as measured by the sum of the containers heights along a vertical corner of the container stack between the terminal shoulder elements (2), so that the boxes or containers absorb part of the load before the pillar element (1) comes into contact with the upper terminal shoulder.

A corner post for a plastic film wrapped package include a first corner post leg and a second corner post leg that intersect at a post corner. The outer wall of the first corner post leg includes a plurality of recessed areas extending inward from an outer surface of the outer wall and are longitudinally spaced to define a plurality of ribs along the outer wall. The recessed areas and ribs are spaced so that the ribs of corner posts of adjacent packages mesh to prevent relative vertical movement of the packages. The post corner of the corner post may include longitudinally spaced recessed edge contours extending inward that grab plastic film as it is stretched or heat shrunk around the package to prevent the plastic film from sliding along the corner post.

The invention relates to a stackable tray comprising an outer sheet with foldable tabs that fold around an inner sheet, and columns glued to the inner sheet. The outer sheet is glued to the columns and the tabs are glued to the inner sheet. The folder is the same tray but with an added cover glued to the left side of the tray. The trays or folders can be stacked one on top of the other, the inner sheet being supported on the columns, the columns being supported one on top of the other. The trays have side labels that allow them to be identified from the side when they are stacked, and a front label that allows the cover to be identified in the case of a folder.
