A carton is formed from a blank of cardboard or paperboard by folding the blank along preformed score lines or fold lines. The carton has front and rear walls, opposite side walls, corner walls, and top and bottom walls defining an enclosure for receiving the contents. Tabs are attached to the top and bottom walls at the corners and are folded downward over the corner walls to prevent light from entering the space between the corner walls and the top and bottom walls. Slots can be provided in the corner walls, and the ends of the tabs inserted into the slots to retain the tabs in a flush position against the corner walls.
