Abstract
Improvements for a low energy fuse inserted into a blasting cap wherein the fuse is in the form of a hose and the blasting cap comprises a tubular cover containing an explosive and optionally, a delay detonator. The tubular cover receives the hose so that the end of the hose is in facing relation with the detonator or explosive. A moisture-proof barrier is disposed between the fuse and the explosive or detonator and comprises a diffusion-tight rigid tube inserted into the hose and having a flange extending outside the hose in abutment therewith. A diffusion-tight film or foil covers the flange to seal the interior of the tube and thereby the hose from the interior of the cover. The film or foil is ruptured by the blast wave upon detonation of the hose.
