  • Patent number: 5071005
    Abstract: A shipping container for holding a variable number of drill bits immobile, thereby preventing potentially damaging contact of the drill bit points with interior walls of the container has a concave base section hingedly connected to a symmetrically-shaped lid section which is pivotable downwards into contact with the base to form a closed, rectangular box-like enclosure. Rows of cylindrical pins protrude upwards from the upper surface of the bottom wall of the base and are adapted to be insertably received in bores provided into the lower surface of an elongated, slab-shaped drill bit carrier, each row of pins thus holding a separate carrier in a horizontally fixed position relative to the base.
