Abstract: A container defined by a base and cover, with the cover being formed to fit upon the base. The base and lid are formed so that when fitted together at least one wall of each overlaps a wall of the other. The overlapping walls are formed with an aperture which become aligned when the cover and base are fitted together. The container further includes a fastening hasp attached to either the cover or the base. One end of the hasp end is formed to pass through the aligned apertures in only one direction. Once the hasp end is positioned through the aligned aperture any attempt to remove the hasp therefrom brings a portion of the hasp into contact with the wall defining the aperture. This prevents the removal of the hasp from the aligned apertures. The hasp is further formed with a tab which can be grasped and pulled causing the hasp to tear along a pre-scored line.
