A lunch box carton made from a single cardboard blank with an attractive reclosable gabled top and an auto-erecting lock bottom. The lunch box carton has a tapered side wall construction, forming an inverted truncated pyramidal configuration to enable stacked nesting of a plurality of the cartons. The lunch box carton is of a knock-down variety which can be shipped in a flattened configuration and is further provided with an auto-erecting lock bottom to facilitate erection of the carton. The top portion of the carton is attractively gabled in configuration, providing additional interior volume, and includes integral carrying handles. Further, the carton is provided with movable wedge shaped locking portions pivotally connected on the top of the carton which can be interengaged with apertures provided in the side wall of the carton, to securely lock the carton in the closed condition. In addition, to prevent lateral shifting of the top of the carton, the carrying handles are secured by folding tabs.
