1 Claim.

The invention relates to an hermetically sealed metal container for time fuses and the like.

An object of the invention is to provide a container of the above type wherein the ends which are attached to the body portion thereof are shaped so as to conform to and contact with the nose and butt ends respectively of a time fuse to prevent endwise and lateral movement of said fuse within the container.

A further object of the invention is to provide a container of such construction that the portion of the ends attached thereto which contact with the fuse, will yield to accommodate variations in the length of fuses.

A still further object of the invention is to provide a container of the above type, wherein the central formations in the ends, which con form to the ends of the fuse, are disposed within a plane tangent to the double seam joining the respective ends to the body of the container so that containers may be placed one upon another for shipment or storage purposes.

Referring to the drawing:

Fig. 1 is a side view showing the manner in which the containers may be stacked for shipment, one of said containers being in vertical section showing a time fuse held within.

Fig. 2 is a top plan view of the container.

Fig. 3 is a sectional View of the container looking toward the bottom end.

Fig. 4 is an enlarged sectional view of the upper end of the container taken at the double seam.

The invention relates to a container for hermetically packaging time fuses and the like. Thecontainer consists of a body portion of metal having its side edges joined by the usual type of lock and lap seam. Metal ends are double seamed to the container body by any standard type of closing machine. One of said ends is depressed, forming a panel, and within the panel is a curved raised central dome portion which is adapted to conform to and contact with the nose end of a time fuse. The other of said ends is depressed outwardly to form a retaining seat for the butt end of the time fuse. The formations in the ends are dimensioned so as to always contact with the respective nose and butt ends of the time fuse and prevent any endwise or lateral movement of the fuse within the. con tainer. The formations in the ends are each disposed within a plane tangent to the respective double seams joining said ends of the container body so that one container may be stacked upon another for shipment or storage purposes.

Should there be slight variations in the lengths of time fuses, the ends will yield centrally thereof to accommodate the same.

Referring more in detail to the drawing, the improved container for time fuses is indicated at 5 5. A time fuse F having a nose end N and a butt end B, is shown within a container in Fig. 1 of the drawing. The container comprises a metal body portion 6 with metal ends 1 and 8 double seamed thereto in the well known manner. The 10 double seam is indicated at 9 in the drawing. The end 1 of the container has a depressed portion l0 and centrally thereof has a curved raised dome shaped portion II which is adapted to contact with and conform to the nose end N of the time fuse. The other end 8 is provided with an outwardly extending central depression I2 which forms a seat for the butt end B of the time fuse. The diameter of the central depression 12 is substantially the same as the outer diameter of the butt end B of the fuse. It can be readily seen from the drawing that with both ends secured to the container body, the parts H and I2 of the respective ends 1 and 8 which conform to and contact with the nose and butt ends of the fuse, will hold the same from any lateral or endwise movement in the container.

As further shown in Fig. 1 of the drawing, the outer extent of the formations II and I2 in the ends 1 and 8 are each within a plane tangent to the respective double seams so that one container may be stacked upon another with the double seams contacting without interference from the formations II and I2. It will be further noted that the formations l and 12 in the ends l and 8 are located centrally therein and the metal in the region thereof will yield to accommodate slight Variations in length of time fuses.

From the above it will be apparent that a container has been devised for hermetically sealing time fuses, wherein the fuse is held from possible endwise and lateral movement which might cause damage to the delicate parts thereof. The container being hermetically sealed, protects the fuse from moisture which might damage or render the fuse useless. Also a container has been devised which may be stacked for shipment or storage in a comparatively small space, as there are no projections on the exterior thereof to prevent the close packing of the same. The container as described lends itself to vacuumization or filling with an inert gas which would prevent deterioration of the material contained in the fuses.

It is obvious that minor changes in the details of construction and arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claim.

I claim: 7

An hermetically sealed metal container for time fuses and the like comprising a body portion, a top end seamed thereto, saidrend having the central recess thereof shaped to conform to the nose of said fuse with the portions of the end between said recess and the seam substantially flat and parallel to a plane containing the seam, and a bottom end portion seamed thereto and having a central recess shaped to conform to the bottom end of the fuse, said bottom end between said last-named recess and the seam being substantially flat and parallel to the plane of said seam, said ends being positioned so as to yieldingly contact with the nose and the bottom end of the fuse for preventing the same from the lateral endwise movement in the container.
