Packaging container and blank thereof

Abstract

A packaging container has a bottom part including a bottom wall, a front wall, a rear wall, and side walls, and has a lid part comprising a top wall, a front wall, a rear wall, and side walls. The rear walls are pivotably connected with a swivel joint line there between. A locking means for the bottom and lid part is provided for releasably closing the container. To improve such a container in a way that the container can be used for consuming the food as long as possible directly from the container, and to also allow easy access to the food, even if it is already partly consumed, at least—one tearing line for dividing the container is formed perpendicular to the swivel joint line in the front walls, rear walls, and bottom and front walls of the bottom part and lid part. A two-dimensional blank for forming such a packaging container is also disclosed.
