ABSTRACT:
A gabled carton is set forth that is comprised of a top gabled portion, a bottom gabled portion and a bottom fin extending from the bottom gabled portion. The bottom fin has a distal seal extending lengthwise along the bottom fin at a location between the bottom gabled portion and an outer edge. There is also a proximal seal on the bottom fin and it extends lengthwise along the bottom fin at a location between the bottom gabled portion and the distal seal. There is a relieved area on a central portion of the proximal seal. Both of the seals extend lengthwise along the entire length of the bottom fin. The proximal seal is shallower than the distal seal. The relieved area extends above and below the proximal seal and is centered on it.
