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.

A tray and corner post type packaging system for shipping and displaying palletized products is provided. The packaging system is made from three folded and glued blanks and includes four corner posts and a central support.

The present invention provides a carton structure, comprising: a confined body portion having four side wall portions formed by four rectangular boards, and bending portions formed between the side wall portions; a top cover at top of the confined body portion and configured to match therewith; a bottom cover at bottom of the confined body portion and configured to match therewith; wherein at least two supporting members attached onto surfaces of the bending portions; two upper and lower areas at outer surfaces of the side wall portions adjacent to the bending portions are formed of at least two openings and two folding portions correspondingly; the openings and the folding portions are connected to each other; and the folding portions can be pushed and bent toward outer surface of the supporting members in order to reach inner surface of the supporting members to be further secured onto the supporting members.

A post for supporting trays of a container comprises a plurality of panel sections including a first panel section. The panel sections form first and second corners positioned adjacent to one side surface of the first panel section and that end up at the interior of the post. The upper trays are desirably supported by the interior corners and also by portions of the panel sections that form the interior corners and by a portion of the first panel section to thereby enhance the support provided to the upper trays. Two of the posts can be positioned together in face to face relationship to form a center post for supporting upper trays. Selected panel sections desirably have upwardly extending locking tabs and cross member support receiving slots. Containers comprising plural trays and such posts are also described.

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.

The present invention relates to a device holding box flaps open and down along the box side walls, and allowing for secure box stacking. The device has two sides joined at a right angle at a junction. The device has an inside wall with two sections. The device has an outside wall with two sections. The inside and outside walls are joined with a rail, also having two sections. The inside wall is perpendicular to the rail, and the outside wall is divergent from the inside all relative to the rail. The inside wall, outside wall and rail define a cavity that can be slid onto a box to hold two flaps in an open position. A rim with two sections upstands from the rail. The rim is located on the middle of the rail so that a bottom of a stacked box is stacked in a secure manner.

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 fixing element for orienting vertically stacked cuboid containers has first and second vertical sidewalls and a connecting element wherein the first sidewalls form a right angle with each other and the second sidewalls face the outer sides of the first sidewalls. The fixing element can be form fittingly fastened on the corners of a container, wherein a further container is arranged on the fixing element and is fixed in its horizontal position relative to the first container. The fixing element can be easily released again and reused. An embodiment is disclosed with a connecting element as spacer whereby a spacing of two containers is achieved. When two containers are thus stacked with their upper open sides facing each other a third container can be accommodated therein.

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).
