Abstract: A point-of-purchase product display box having an adjustable length for the receptacle. The display box comprises first and second telescopically-engaged segments each of generally rectangular parallelepipedon configuration with back panels, a pair of side flaps, and one end flap, all extending at right angles from the back panel. The side flaps of each of the first and second segments have spaced-apart rows of aligned bores formed therein along row axes generally parallel to the common juncture line between the side flaps and the back panel, including an upper row and a lower row with the axes of the separate rows being aligned, and with a number of bores being arranged to permit telescopically-engaged relationship between the segments in either closely coupled or elongated relationship so as to accommodate the available space at the point-of-purchase location.
