Abstract: Alveolate container for the packaging of explosive primers includes a bottom half having a plurality of alveoli arranged in parallel rows. Each alveolus is configured for housing an explosive primer for firearm cartridges with the percussion surface of the primer positioned near the mouth of the alveolus and a space defined between the concave bottom and an end of the primer opposite the percussion surface. The container also includes a cover half hingedly-connected to the bottom half and configured for hingedly closing upon the bottom half for substantially isolating the mouths of the alveoli from the outside of the container. The cover half includes a rib corresponding with the center line of each row of alveoli to constitute, upon closing, a limit to the movement of the primers from the mouths of the alveoli. Preferably the container is formed from a single piece of plastic material.
