Blank and gable top carton thereof

Abstract

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.

1 . A blank comprising:
 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; at least one of the plurality of panels having a fluorescent whitening agent on all or a portion of an inner surface of the top portion of the at least one panel wherein 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:
 a body having a plurality of side walls consecutively articulated to one another along parallel fold lines, a plurality of panels configured to cooperate with one another to define a gable top having first and second sides and a bottom of the sealed carton, at least one of the plurality of panels of the gable top includes a fluorescent whitening agent on all or a portion of an inner surface of the first side of the gable top wherein at least one panel glow when subjected to a black light, the second side of the gable top being fused to one another and wherein the first side of the gable top define a pour spout formed by the plurality of the panels wherein the pour spout is capable of periodically opened and closed to access the material stored in the carton.
