The invention relates to a modular structure for a cardboard tower-like display, made up of shelf modules (a) each of which is made up of a cardboard sheet with a four-sided central area (10) whose corners form incoming vertexes (12) and whose sides are folding and flapping lines with respective flaps thereof; together with straight tubes which feature stud modules (b), with the same cross section than the perimeter tubular edges (11) of each shelf module (a), and connecting elements in the shape of corner studs (c), each of which has a central part (30) with arms (31), (32) and (33) projected into three orthogonal spatial directions which fit into the concurrent ends of the tubular edges (11) of each shelf module (a), and the ends corresponding to the tubes which constitute the stud modules (b).

A pallet assembly including a plurality of trays separated by supports is provided. Each of the supports includes a rectangular portion and a wing portion. The wing portion is formed from two layers of materials connected together by a locking tab or other suitable structures. The wing portion can include a first portion and a second portion at an angle with respect to the first portion. A tab can be used to facilitate placing the first portion of the wing at the angle with respect to the second portion of the wing.

A pop-up display apparatus. The apparatus includes a knuckle defining a pivot axis and having a pair of parts, the pair of parts being pivotally connected to one another for relative movement about the pivot axis. A base portion is connected to one of the pair of parts. The apparatus includes a leaf portion connected to the other of the pair of parts for pivotal movement relative to the base portion about the pivot axis and a tab portion movable relative to the leaf portion between a released position and an engaged position.

Disclosed herein is a display unit that is rugged, re-usable, and configured for quick (and tool-free) assembly. The display unit includes a foldable frame with a scannable display code. The foldable frame is also configured to support at least one shelf, and the at least one shelf has one or more item codes that are distinct and separate from the scannable display code. Each of the item codes respectively identifies one or more products to be placed on the shelf. In some embodiments, the foldable frame of the display unit is pre-adhered (e.g., a first side panel and a second side panel are adhered along respective vertical fold lines to a back panel) and desired shelf heights for the display unit are pre-configured before shipment of the display unit to a merchant. In this way, the display unit can be quickly constructed by the merchant with the desired shelf heights.
