Abstract
A clamshell carton formed from two integral blanks of sheet material. The front wall of the upper clamshell carries a latching aperture. The front wall of the lower clamshell half carriers a latch release panel, the latter carrying a horizontally despaired latching tongue normally engaged in the latching aperture to maintain the clamshell in a closed configuration. The latch release panel is normally resiliently biased to maintain the latch tongue engaged. The front wall of the upper clamshell half is provided with a recess along a free edge, the recess permitting direct finger force to be applied to the latch release panel to open the carton by disengaging the latch.
