Abstract
Abstract A carton for ice cream, ice milk, sherbet, mellorine and like products is shown, particularly proportioned for a half-gallon capacity having top and bottom panels with a length to width ratio of approximately two to one, preferably this ratio is two to one or greater, front and rear panels having a length to height ratio of more than two to one, and front tear tab opening means which constitute less than ten percent of the perimeter dimension of the carton taken around its width and height. Various embodiments having opposed closure flaps of varying constructions are at each end of the carton ranging from full closure to full closure with a recess for nesting or partial closure with a thumb tab for the same capacity with reduced board usage. The carton blank is susceptible of being manufactured on a milk carton blank machine, and the blank length at any location is held to a maximum of about 15.7 inches. The side seam flap itself is less than ten percent of the total perimeter dimension, and the preferred embodiment is sealed with a line of weakness adjacent the upper edge of the front panel so that upon tearing, the paper is torn from the outer face of the covered portion of the front panel in a strip generally parallel to the upper cut-out portion of the front panel.
