Blank and gable top carton thereof
The present invention relates to a bank and a gable top carton constructed therefrom. The blank comprises a plurality of panels having top portions. The top portions of the plurality of panels are cooperated with one another to define a gable top. The plurality of panels are consecutively articulated to one another along parallel fold lines. At least one of the plurality of panels includes a fluorescent whitening agent on all or a portion of an inner surface of the top portion of the at least one panel. The top portion of the at least one panel glow when subjected to a black light.

2 . The blank of claim 1 is constructed to form a gable top beverage carton.
3 . The blank of claim 1 wherein the plurality of panels includes a rectangular first side panel, a rectangular second side panel, a rectangular third side panel, a rectangular fourth side panel, and a rectangular side seam panel which are consecutively articulated to one another along parallel fold lines, respectively.
4 . The blank of claim 3 wherein each of the rectangular first side panel, the rectangular second side panel, and the rectangular third side panel receives the fluorescent whitening agent on all or a portion of the inner surface of the top portion of the panels.
5 . The blank of claim 4 wherein each of the portion of the inner surface of the top portion of the panels define as a region A, a region B, and a region C wherein the regions A, B, and C cooperate with one another to form a pour spout of the gable top beverage carton.
6 . A method of producing a blank having a plurality of panels having top portions, the top portions of the plurality of panels cooperate with one another to define a gable top, the plurality of panels consecutively articulated to one another along parallel fold lines, the method comprising the steps:
applying a fluorescent whitening agent on all or a portion of an inner surface of the top portion of the at least one panel of the blank; and
subjecting the portion of the inner surface of the top portion of the at least one panel of the blank having the fluorescent whitening agent to a black light so that top portion of the blank glow.
7 . A sealed carton comprising:
