Abstract
Abstract A self-erecting end-loading top-dispensing container which is convertible from a substantially flattened configuration for shipping the empty container into an erected box-like configuration for loading product into the container and for shipping loaded containers. By removing a tear-away portion of the top panel, the container is convertible into a tray having an open top for dispensing product. Connecting webs join the end closures of the container to the front and rear side walls, preserving the structural integrity of the container when the removable top is torn away.
