HERMETICALLY SEALED CARTON Abstract Of The Disclosure In accordance with the present invention a paperboard con- tainer is provided with a hermetic end closure. The manufact- urers flap, which is of unique construction, is foldably con- nected to an adjacent ungussetted panel. During the folding sequence, the manufacturers flap is sealed to a gussetted panel and the gussets at either end of the container are then caused to be moved outwardly to form projecting wings, and then the inner surfaces of the rib panels are brought into juxtaposed alignment for sealing engagement to form a continuous and uninter- rupted hermetic closure.
