A flat-top, hermetically sealed, paperboard-based container and apparatus and method of making it are set forth. The paperboard-based container includes a rectangular sleeve having upper end sections joined at fold lines with side walls. The upper end sections are divided into inner and outer opposed pairs which are folded toward one another in an overlapping manner to form a generally flat end for the container. Each of the inner and outer opposed sections includes a cutout. When the upper end sections are folded in and overlapping manner, the cutouts define an aperture having edges that include exposed paperboard substrate. Each of the inner pair of opposed end sections are divided along fold lines into a middle region and laterally opposed side regions. The laterally opposed side regions are folded onto the middle region and are sandwiched between the middle region and the outer pair of opposed sections when folded to form the container top. One of the outer pair of opposed upper end sections is longer than the other so that the longer outer end section overlaps exterior to the shorter of the outer pair of opposed upper end sections. An opening fitment is disposed through the aperture and includes a flange at the interior of the container. The flange covers the exposed edges of the aperture. The fitment is preferably a resealable cover, such as a resealable screw-type spout and cap or the like. |
