ABSTRACT:
A process for affixing reclosable pouring fitments having pouring apertures to erected cartons. In a first embodiment, adhesive is initially applied to the rear of the fitment in two parallel strips on opposite edges of the fitment. Then, the fitment is rotated 90 degrees and two more parallel strips are applied to the other two edges of the fitment. The orientation of the second set of strips is generally perpendicular to that of the first set and is such that the strips form a rectangle which surrounds the pouring aperture of the fitment. The fitment is then applied to the carton over the dispensing aperture of the carton. The generally rectangular pattern of adhesive surrounding the carton's dispensing aperture effects a continuous seal between the fitment and the carton and minimizes leakage of the product out of the carton when fitment is closed.
