ABSTRACT:
The carton is comprised of a corrugated paperboard tray and a corrugated paperboard cover. The tray has upstanding side wall panels and upstanding end wall panels, the upstanding end wall panels having hand holes for lifting the tray. The cover has a top panel provided with a non-slip surface, trapezoidally configured side wall pane=ls and trapezoidally configured end wall panels. Each of the side wall panels and the end wall panels of the cover are hingedly connected to the top panel by reason of weakened fold lines. The corrugations of the cover extend at right angles to the fold lines for the cover's end wall panels so as to provide a greater degree of deflective resistance to the cover's end wall panels then that imparted to the cover's side wall panels with the consequence that the end wall panels of the cover exert a greater amount of pressure against the end wall panels of the tray than that exerted by the cover's side wall panels. However, the end wall panels of the cover are dimensioned so as to fit within the side wall panels of the cover and thus exert a pressural action against the side wall panels of the cover, thereby increasing the amount of frictional retention force of the side wall panels of the cover against the side wall panels of the tray than would otherwise occur. A paper mat or doily has a non-slip upper surface. Containers can be dimensioned so as to engage both non-slip surfaces.
