ABSTRACT:
An identification button construction for a paperboard clamshell carton or container. An edge of the carton lid, such as a horizontal edge, is provided with a plurality of cuts or scores which form the periphery of individual identification buttons. Such buttons are used to indicate the presence or absence of an ingredient or garnish for a hot food item such as a hamburger sandwich. The peripheral scores or lines of the button are cut about half way through the paperboard from the outer carton surface towards the carton interior. An elongated Z shaped cut, completely through the paperboard, bisects the button, at a right angle to the crown edge. The crown edge also bisects the button. While a diamond shape button is illustrated, round, oval, or other polygonal shapes may be employed. In use, a button is finger pressed toward the carton interior and assumes a depressed configuration, different from its original configuration, thus indicating the presence or absence of a garnish or other ingredient for the packaged food item.
