ABSTRACT:
A container for housing granular materials and a blank for forming the container. The container is a six sided enclosure including a top wall, a back wall, a bottom wall, a front wall and two end walls. The front wall has an inner layer and an outer layer. The outer layer has a transverse tear strip therein and is attached to the inner layer below this tear strip. A glue flap is attached to the interior surface of the top wall and also attached to the top edge of the inner layer of the front wall along a perforated cut line. This configuration prevents the granular material from migrating between the layers of the front wall during shipping. Each end wall is comprised of several layers. Included are two main layers which together have a top edge. A tear strip panel extension is attached to the main layers below the tear strip. An ear is attached to the tear strip panel extension above the tear strip and also attached to the top wall. The ear holds the top wall against the top edge of the main layers to prevent the granular material from migrating between the tear strip panel extensions and the main panels during shipping.
