Abstract
There is provided a carton and a blank therefor having top end flaps connected to the front, rear and side panels of the carton blank wherein a first top end flap connected to either the front or back panel of the carton blank is adapted to overlap a second top end flap disposed opposite to the first top end flap and which is connected to the remaining front or back panel of the carton blank. The first or overlapping top end flap is tightly adhesively connected to the second or underlying top end along the length of the outer edge of the first flap and the opening feature for the carton top is provided by a tear strip in the overlapping first end flap between the adhesion area thereof and the score or fold line connecting the flap to the connecting front or rear panel, as the case may be. The tear strip consists of a removable strip extending the length of the flap which cleanly and completely separates therefrom so that the first flap can be separated from the second flap. The tear strip includes a tape like element formed of a hot melt string which is adhered along the inside of the flap along the desired path of the tear strip and defines the tear strip when the tape like element is torn through the sheet material of the flap.
