Foldable carton tray

Abstract

A foldable carton tray and a blank therefor which is formed with longitudinal and lateral fold lines parallel to the boundaries of the blank to delineate respectively side and end panels connected by corner panels and all surrounding a centre panel, each end panel having diagonal fold lines extending from the adjacent intersections of said longitudinal and lateral fold lines towards but stopping short of the edge of said panel to delineate a first trapezoidal shaped flap with a tongue extension formed by two cut extensions of said diagonal fold lines opening into said edge, and the centre panel having three cut lines near each end to delineate at each end a second trapezoidal shaped flap which has a common base with said first flap and is complementary to the latter. The blank is preferably constructed so that at each end downward folding of said first trapezoidal shaped flap at 90.degree. to the centre panel causes the adjacent corner panels to swing round to the carton end and causes the second trapezoidal shaped flap to swing into a vertical position to complete the carton end wall.
