Abstract

A tray-type package for receiving a series of articles is constructed from a blank which enables the user to vary the size of the horizontal surface on which the articles are placed. The blank includes a bottom panel and a series of side walls which are interconnected with the bottom panel via connection structure which defines a series of fold locations, and the user selects the appropriate fold location according to the size of articles being packaged such that, when a predetermined number of articles are placed on the tray, the outer articles are in close proximity to, or engage, the tray side walls. When the tray side walls are folded at the different fold positions, the position of the adjacent side wall ends varies, and retainer structure is interposed between the side wall ends which accommodates such variation and which secures the side walls together. The retainer structure is an extension section formed on one of the side walls which overlaps the other side wall. The extension section includes tab structure receivable within one of a series of slots formed in the other side wall, for interconnecting the side walls.
