Portable display containers and methods of making and using the same

A method of using a portable display container comprising:

• a) placing a plurality of items in the portable display container, the display container comprising:
• i) a plurality of display tiers in a stack, each display tier comprising:
• a base tray comprising (A) a bottom panel, (B) two side panels, each of the side panels attached to the bottom panel at an angle of about 90° relative to the bottom panel, and (C) two end panels, each of the end panels attached to the bottom panel at an angle of about 90° relative to the bottom panel;
• at least one spine, each spine comprising two spine flaps, each spine flap attached to a spine ridge at an angle of about 90° relative to the spine ridge and having at least two spine slots, wherein the two spine flaps and the spine ridge remain rigid when the display tier is loaded with product and stacked;
• two or more cross supports, each cross support comprising two cross support flaps attached to a cross support ridge at an angle of about 90° relative to the cross support ridge and having at least one cross support slot configured such that the at least one cross support slot mates with the at least one spine at one of the spine slots, wherein the two cross support flaps and the cross support ridge remain rigid when the display tier is loaded with product and stacked;
• ii) a portable platform, wherein the base tray of each display tier rests on or is in contact with the portable platform or another display tier of the stack;
• b) placing inside corner posts within the corners of each display tier, wherein each of the inside corner posts extend from near the bottom of one base tray of the display tier to at or near the bottom panel of the next display tier above in the stack;
• c) wrapping the portable display container with protective material;
• d) moving or transporting the portable display container to a display location;
• and
• e) removing the protective material.

A method of forming a portable display container with a plurality of tiers in a stack, comprising,

• a) assembling a display tier by:
• i) forming a base tray by (A) folding each of two end panels at an angle of approximately 90° with respect to a bottom panel of a blank for a base tray, (B) folding each side panel of two opposing side panels at an angle of approximately 90° relative to the bottom panel;
• and (C) attaching each of the end panels to one of the two side panels;
• ii) forming at least one spine by folding each of two spine flaps at an angle of about 90° relative to spine center portions of a spine blank to form a spine panel, two or more spine slots and a spine top ridge;
• iii) placing the at least one spine into the base tray such that the spine contacts and/or is attached to the end panels of the base tray;
• iv) forming at least two cross supports by folding each cross support flap of two cross support flaps at an angle of approximately 90° relative to a cross support center portion of a cross support blank to align cross support cutouts and form a cross support panel with at least one cross support slot and a cross support top ridge;
• v) inserting into and/or mating each of the cross supports with one of the spine slots of the spine(s) such that the spine top ridge and the cross support top ridge are in the same plane and such that the cross support contact the corresponding side panels of the base tray;
• b) placing the display tier on a portable platform or on another tier of the stack of display tiers;
• and
• c) repeating steps a) and b) for each tier of the portable display container.
