Claims.

This invention relates to a container for explosives which is employed for packing, storing and handling of the explosive, and also includes parts whereby the explosive may be prepared for detonation without opening the container.

In such a container it is desirable that the package be maintained as a unit, and the service of attaching a detonating agent should be conflined to a minimum of manipulation. Furthermore, it is often desirable that the container should be of relatively light and thin material and hence any openings would constitute a weakness in the structure: and a feature of the present invention is the inclusion of means whereby necessary openings are compensated by reinforcing material.

A further feature of the invention is the provision of a structure which can be easily and simply manufactured and can be made to enclose the explosive in a sealed and weather-tight condition.

An illustrative form of the package is shown in the accompanying drawings:

Figure 1 is a perspective view of the filled and sealed container.

Figure 2 is a longitudinal sectional view on an enlarged scale substantially on line 2—2 of Figure 3.

Figure 3 is a transverse sectional view substantially on line 3—3 of Figure 2.

The container is illustrated as formed of a body 10, which may be of sheet metal such as tin plate, having the ends of the seam edges of the blank joined by a body seam I ( in the usual way. The ends 12, 13 are illustrated as of slip type for engaging around the ends of the body 10, but it will be understood that these ends may be formed in another manner for assembling to the body by other means. When the explosive is subject to variation in contact with moisture or other air conditions, it is preferred to complete a hermetic seal by sealing means (4, which, for an explosive that is not sensitive to soldering temperatures, may be provided by a soldering operation.

The body is illustrated as provided with aper;ures 16, f 7. In the illustrated form, the aper;ure 16 is of lesser length than the aperture 17. rhese apertures are located remote from the ends )f the container, so that they remain easily accessible.

A plate 20 of heavier material, such as steel, is «cured to the body at the inner surface thereof, md is sealed to this body. It has been found hat soldering or brazing secures an adequate (Ci. 102—24) attachment and seal. This plate 20 has a longitudinal slot therein terminating short of its ends and illustrated as having a length equal to the distance between the outer ends of the holes 5 16, 17. ·.

The plate 20 receives a member 21 which has a rib 22 projecting therefrom inwardly into the space within the container body 10. The ends and longitudinal edges of the member 21 are en10 gaged with the plate 20, and are secured and sealed thereto as for example by a soldering operation. It will be noted from Figure 2 that this rib provides a trough co-extensive with the slot in the plate 20. This trough is closed by the 15 adjacent parts of the body wall, except at the openings 16, 17, so that a tunnel is formed which is sealed from the interior of the container and has closed ends, but communicates with the exterior through the openings 16, 17, which are 20 located laterally of the axis of the tunnel so that in introducing a fuse cord, this cord must, be bent at the openings in order to pass it into and through the tunnel.

When the body 10 has been assembled with an 25 end 13, it can be filled with the explosive and then the other end 12 applied. Upon sealing, the package is hermetically-proofed against atmospheric influence.

In using the container of explosive, a fuse such ³⁰ as a detonating fuse is inserted through either aperture 16, 17 and passed along the tunnel formed by the member 22 and the inner surface of the body 10. Upon detonation of the detonating fuse, the explosive effect is transmitted 35 through the wall provided by the member 22 and thus detonates the charge of explosive, with or without causing rupture of this wall prior to the detonation.

It will be noted that the plate 20 serves for re⁴⁰ inforcing the body 10 at the region of apertures 16, 17 by preventing distortion of the body such as by an inward movement to collapse the tunnel whereby trouble would be encountered in intro_4g ducing the fuse, and also serves to reinforce the body at the moment of ignition and provides assurance that a maximum effect will be applied to the inner wall of the member 21 to detonate the charge.

In the illustrated form, two openings 16, 17 have been illustrated, thus prQviding a structure in which two detonating fuses may be employed for assuring detonation, or the openings may be

Employed for the passage of a single length of det56 onating fuse which is used for detonating a

2,426,472 number of the containers with essential simultaneity. By having the aperture 17 of proper length, it is feasible to employ time fuses and detonating caps in lieu of the detonating fuse when so desired: while the short opening 16 con- 5 ditions a relatively short angle in the detonating fuse when the container has been serviced for detonation, so that the detonating fuse will not slip from position.

It is obvious that the invention is not limited 10 to the form of construction shown, but may be employed in many ways in the scope of the claims.
