Claim 1
Independent Claim
350 words
A container blank comprising first, second, third and fourth panels serially connected by first, second and third score lines, means for connecting said first and fourth panels in the completed container, two of said first, second, third and fourth panels being opposed side walls in the erect container, the other two of said first, second, third and fourth panels being opposed front and back panels in the erect container, bottom closure panels extending from selected lower edges of said first, second, third and fourth panels along a fourth score line, said bottom panels attached to said front and back panels each having a diagonal score line to form a fold back section and a converging relief at the midpoint of the outer free edge thereof, said diagonal score lines being parallel to each other and extending inwardly from said relief, said bottom panels attached to said side walls being truncated, a front reinforcing panel being hingedly attached along a fifth score line to the upper edge of said front panel, the length of said front reinforcing panel being substantially equal to the height of said front panel and the width of said front reinforcing panel being substantially equal to the width of said front panel, side reinforcing panels hingedly attached along said fifth score line to the upper edge of each of said side panels, said side reinforcing panels having a length substantially equal to the height of said side panels and a width substantially equal to the width of said side panels, a back reinforcing panel being hingedly attached to said back panel along said fifth score line, said back reinforcing panel having a length substantially equal to the height of said back panel and a width substantially equal to the width of said back panel, bottom reinforcing panels attached to the outer edge of said reinforcing panels along a sixth score line, each said bottom reinforcing panel being rectangular and of equal length extending from said sixth score line to a distance which when the carton blank is erected the opposed bottom reinforcing panels will overlap each other.
