Abstract
A rectangular paperboard container includes an improved opening top structure which, when opened, provides a completely open top container. The container includes a tear line which extends substantially along the front and two side upper edges of the container. The tear line defines an openable top portion of the container which, when opened, is hingedly attached along the rear upper edge of the container. Preferably, the front tear line is located in a front panel of the container, and is spaced slightly downwardly from the front upper edge. The side tear lines can be located in either the respective side panels or in a top cover, and are also spaced from the respective upper side edges. In accordance with the present invention, an opening tab is operatively connected to the container along the upper front edge thereof. The opening tab is adapted to be folded against the front panel and substantially covers and protects the front tear line.
