ABSTRACT:
A flip top dispenser box is formed from a single, integral planar paperboard blank which is folded into a generally rectangular parallelopiped, and is sealed along lines of weakness joining an upper and lower portion of the opposed side walls and front wall of the box. The line of weakness along the front wall is characterized by a cut line interrupted by at least two spaced arrays of non-linear perforations, while the line of weakness along each side wall is characterized by a cut line leading to a series of perforations disposed in parallel relationship and at a predetermined angle relative to said cut line. The arrays of non-linear perforations and the series of parallel perforations provide structural integrity for maintaining the flip top dispenser box in its sealed condition, until such time as the seal is broken so as to gain access to the contents of the box by rotating the cover of the box to sever the perforations.
