ABSTRACT:
In a blow-molded, cylindrical plastic container for explosives adapted for end-to-end coupling with like containers, an improvement is provided in the sealing of the container at the exposed explosives end. The improvement comprises a section of reduced diameter in the portion of the container immediately beyond the point of connection of a like container. The section of reduced diameter is adapted to receive therein a resilient plastic, disc-like sealing member in fluid-tight engagement. The seal prevents contamination of the explosive yet yields upon the pressure exerted by an adjacent, connected container.
