DETAILED DESCRIPTION OF THE INVENTION

[0024] The present utility model corresponds to a container or receptacle (1) for containing a mixture, preferably pentolite, used to initiate a blasting process.

[0025] The container (1) comprises at least two parts, a lower part (2) which is intended to contain the mixture of explosive material, and an upper part or cover (3) intended to maintain the structural unity of the container and prevent the mixture from leaving of the container (1).

[0026] The lower part (2) comprises an elongated hollow structure, preferably of circular cross-section, wherein the lower part (2) shows a cylindrical geometry in a first embodiment, and in a second embodiment the lower part (2) shows a conical geometry, tapering to the base of the lower part (2) of the container (1).

[0027] Inside the lower part (2) a duct or pin (4) is placed, which preferably shows a cylindrical shape, and extends from the base of the lower part (2) of the container (1) to a defined distance of the upper end of the lower part (2), where the duct or pin (4) is opened at both ends. The duct or pin (4) is reinforced to the base of the lower part (2) of the container (1) by a plurality of reinforcing parts (5), which reduce the risk of bending of the duct or pin (4) due to the load of the mixture. The duct or pin (4) is placed in an eccentric position of the section of the lower part (2) of the container (1), i.e., it is arranged in a position different from the central symmetry axis of the lower part (2). In the upper part of the lower part (2) of the container (1), particularly on the inner surface, at least two stops (6) are provided to allow the closure of the cover (3) of the container (1) at the moment of placing said cover.

[0028] The cover (3) comprises an opening (7) which is supplemented by the upper part of the duct or pin (4) and comprises at least one opening (8) from which a respective duct or pin (9) extends towards the lower part of the cover (3), where said duct or pin (9) is closed in the lower part thereof. Each duct or pin (9) is smaller in diameter than its respective opening (8), thus generating a conical section between the respective opening (8) and its respective duct or pin (9).

[0029] In the upper part of the cover, particularly on its perimeter, the cover (3) comprises at least a pair of hollows (10) that allow the cover (3) to be closed with the lower part (2) of the container (1).

[0030] In that way, the detonator is inserted through the duct (4) and subsequently inserted into the at least one duct (9), being thus placed in the lower part of the container (1), where the highest concentration of PETN is generated.

[0031] To fasten the detonator in each duct or pin (9) a safety device is provided in the conical section raised between the respective opening (8) and its respective duct or pin (9), where said safety device is fastened in the conical section by a fastening countercone (12) and a fastening rod (13). The safety device comprises a grooved opening, which allows fastening and holding the detonator wire in case of traction caused by said wire.
