Abstract: A gusseted reclosable packaging container has a plastic closure device arranged at the upper container edge and extending across the container width. The closure device has closure parts each having a profiled strip with a connecting flap connected to the front wall and the back wall, respectively, by a connecting seam. One profiled strip has a groove-shaped receiving section and the other a tongue-shaped engagement section. The closure device has a slide engaging across the profiled strips such that, when the slide moves along the profiled strips, it pushes the profiled strips together or moves them apart for closing or opening the closure device. The container gussets have upper ends ending below the upper edge and above a lower edge of the connecting flaps or are provided with a cutout. The gussets are closed at the upper ends or at the cutouts by one of the connecting seams.
