ABSTRACT:
A butterfly carton made from a single blank with an auto-erecting lock bottom, and a recloseable top portion including an attractive butterfly wing shaped design. The butterfly 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 carton is provided with movable triangular shaped locking portions, pivotally connected to the top of the carton, which are interengaged with V-shaped slots provided in the side wall of the carton, to securely lock the carton in the closed condition. The top portion of the carton is also provided with butterfly wing shaped tabs which are interengaged to provide secondary locking of the carton. In addition, the butterfly wing shaped tabs are maintained at an angle relative to the top of the carton to create an aesthetically pleasing design.
