ABSTRACT:
A clamshell type carton bottom having integrally connected thereto a domed top with upper portions of side and front panels of the carton bottom defining seats on which there are seated seat members carried by side and front panels of the top and reversely turned so as to slope upwardly and outwardly while the side and front panels slope downwardly and outwardly. Each side panel of the bottom adjacent the front panel of the bottom is provided with a cut line which defines stop means so as to limit the movement of the top into the bottom when the carton is being closed. Further, the bottom front panel is provided with a locking flap which carries a locking tab which engages over the front seat member of the top to lock the top in place relative to the bottom.
