Abstract
The container of the present invention includes polygonal sidewalls with at least some of the upper edges of the side walls each having a container locking flap thereon and with at least one other of the side walls being free from locking flaps. The lid has polygonal edge walls sized to matingly fit over the upper edges of the container side walls. Each of the edge walls of the lid are provided with a lid lock flap which folds upwardly and inwardly with respect to the edge walls and which terminates in an upwardly presented edge spaced downwardly from the top of the lid. When the lid is placed over the top of the container, the lock flaps of the container retentively engage the upwardly presented edges of the lid lock flaps. The lid may be removed after the first locking by severing the lid lock flaps from the lid with a knife or other cutting instrument. The lid may then be locked a second time over the top of the container by rotating it so that the unsevered locking flaps of the lid are placed in registered alignment with the locking flaps on the upper edges of the container.
