A linear shaped charge comprising a body comprising a foam material, a first explosive element, a second explosive element, a liner and a channel at least partly between the first explosive element and the second explosive element. A related structure is also described, with a first cavity configured to receive a first explosive element and a second cavity configured to receive a second explosive element.

Provided herein are shaped charges for focusing a fluid mass and related methods of using the shaped charges for disruption of an explosive target with a spherical projectile. The shaped charge comprises a plastic shell having a special geometric shape configured to support a shape-conforming explosive. A cylindrical plastic body has an interior volume for containing a fluid and the plastic shell. The plastic body closed distal end has a geometric shape that is substantially matched to the shape of the plastic shell. Metal spherical projectiles having an outer layer of metal selected to have an effective density matched to the fluid provide advantageous target disruption capabilities.

The present utility model relates to a container or receptacle for containing a mixture, preferably pentolite, used to initiate a blasting process. Said container comprises at least one lower part intended to contain the mixture of explosive material, and an upper part or cover intended to maintain the structural unity of the container and prevent the mixture from leaving of the container, wherein said lower part comprises an elongated hollow structure with a base, and a duct or pin inside the same, which extends from the base of the lower part of the container to a defined distance of the upper end of the lower part, wherein the duct or pin is opened at both ends, and wherein the cover of the container comprises an opening, which is supplemented by the upper part of the opened duct or pin, and comprises at least one opening, from which a respective duct or pin extends towards the lower part of the cover, where said duct or pin is closed in the lower part thereof.
