Abstract A container cap for a pill container is disclosed wherein the cap provides protection against pill degradation through shaking as well as moisture exposure. The cap is of an integral one-piece construction. A particularly useful application is in the low cost cylindrical thermoplastic pill containers, where the aforesaid protection is necessary without multi-piece construction.
