UONTAINER FOR EXPLOSIVES Filed Aug. 12, 1943 Patented Aug. 12, 1947 2,425,472 y f coN'r'anmR Foaaxmiosrvns Jack Edward Hodgson and Eugene Victor Abel, Memphis, Tenn., assignors to Continental Can Company, of New York Inc., New York, N. Y., a corporation- Application August 12, 1943, Serial No. 498,386

'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 Containeh 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 conined 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 lled 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 I0, 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 Il in the usual way. The ends I2, I3 are illustrated as of slip type for engaging around the ends of the body I0, 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 ls subject to variation in contact with moisture or other air conditions, it is preferred to complete a. hermetic seal by sealing means I4, which, for an explosive that is not sensitive to soldering temperatures, may be provided .by a soldering operation. 1

The body is illustrated as provided with aper- ;ures I6, Il. In the illustrated form, the aper- ;ure IB is of lesser length than the aperture I'I. Ihese apertures are located remote from the ends if the container, so that they remain easilyacsessible.

A plate 20 of heavier material, such as steel, is :ecured to the body at the inner surface thereof, ind is sealed to this body. It has been found ;hat soldering or brazing secures an adequate 3 Claims. .'(Cl. 102-24) attachment and seal. This plate 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 The plate 20 receives a member ZI which has a rib 22 projecting therefrom inwardly into the space within the container body I Il. The ends and longitudinal edges of the member 2| are engaged with the plate 20, and are secured Iand sealed thereto as for example by a soldering operation. It will be noted from Figure 2 that this ribprovides a trough co-extensive with the slot in the vplate 20. 'Ilhis trough is closed by the adjacent parts of the body wall, except at the openings l 6, I1, 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 I6, II, which are 20 located laterally of the axis of the tunnel so that in introducing a fuse cord, this cord mustl be bent at the openings in order to pass it into and through the tunnel.

When. the body I0 has been assembled with an 25 end I3, it can be filled with the explosive and then the other end I2 applied. Upon sealing,sthe package is hermetically-proofed against atmospheric influence.

In using the container of explosive, a fuse such as a detonating fuse is inserted through either aperture I6, I1 and passed along the tunnel formed by the member 22 and the inner. surface of the body I0. Upon detonation of the detonating fuse, the explosive effect is transmitted through the wall provided by the member 22 and inforcing the body I0 ai; the region of apertures l thus detonates the charge of explosive, with or without causing rupture of this wall prior to the detonation. j

I t will be noted that the plate 20 serves4 for re- IG, I1 by preventing distortion of the body such as by an inward movement to collapse the tunnel whereby trouble would be encountered in. introducing the fuse, and also serves to reinforce the body at the moment of ignition and providesL assurance that a maximum effect will be applied to the inner wall of the member 2| to detonate the charge.

In the illustrated form, two openings I6, II

have been illustrated, thus providing a, structure in which two detonating fuses may be employed for assuring detonation, or the openings may bef employed for the passage of a single length of' de tonating fuse which. is used for detonating a number of the containers with essential simultaneity. By having the aperture I1 of proper length, it is feasible toemploy time fuses and detonating caps in lieu of the detonating fuse when so desired: while the short opening i6 conditions a relatively short angle in the detonating fuse when the container has been serviced for detonation, so that the detonatingfuse will not slip from position. f

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

We claim:

1. An explosive container comprising a body gitudinally spaced openings therein, one of said openings being of a length to receive a detonating cap and another opening being shorter, and an internal plate attached and sealed to the body and closing the openings, said plate having an inwardly projecting rib Within its area, said rib extending longitudinally of the body and providing with the adjacent parts of the body a tunnel which is closed at its ends and is sealed from the interior of the container and communicates with the exterior through said openings, said openings and tunnel being constructed and ar-j ranged to permit a length of fuse cord to be passed through the tunnel from opening to opening with the walls of the openings and tunnel effective to maintain bends in the fuse cord at said openings whereby the fuse' cord is held against slipping from position.

2. An explosive container comprising a body' and ends closing the same, said body being ,of light sheet metal and having an opening therein remote from its ends, an internal plate of heavy metal attached and sealed to said body for reinforcing the body at the region including said opening, said plate having a slot extending longitudinally of the body with one part of its length aligned with said opening, and a thin sheet metal member with an inwardly projecting rib formed edges and ends of said member being attached .1s and ends closing the same, said body having 1onr,

and sealed to said plate with said rib providing an outwardly directed trough lying along said slot, the said attachments and seals being effective to close communication between the interior and exterior of the container through said opening, said trough cooperating with the inner surface of the body for` providing a tunnel closed at its ends and extending from the opening for receiving a fuse cord introduced through said opening.

3. An explosive container comprising a body and ends closing the same, saidr body having openings therein spaced longitudinally'from one another and from the ends of the body,` and an inernal plate attached and sealed to the body and. closing said openings, said plate having an inwardly projecting rib within its area and providing with the overlying portion of the body wall a tunnel extending longitudinally of the body and between and communicating with the exterior through said openings, through which openings and tunnel a fuse cord may be passed with the cord bent at the openings and with the angle in the cord at an opening eiective to prevent slippage of the fuse cord from position. l
