FIRST-AID PACKET.

Application filed November 7, 1921.

To all whom it may concern:

Be it known that I, ()rro C. SoHULz, a citizen of the United States, residing at Chi? cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in F irst-Aid Packets, of

. which the following is a specification.

The object of this invention is to provide a strong and compact first aid packet, adaptto ed to be easily assembled to securely hold the contents and maintain the same in a sanitary condition and also adapted to be-readily and easily opened to permit access to the contents.

A further object of the invention is to provide a two part box which can be easily assembled and secured together in an air tight and waterproof manner by means which can be readily removed to permit the parts to be separated.

In the accompanying drawings I have shown an embodiment of the invention which I have selected as a preferred construction from my experience in the manufacture of many millions of first aid packets for use in the great war and referring thereto Fig. 1 is a perspective view of a first aid packet embodying the invention;

Fig. 2 is a collective perspective view of the several parts of the box separated to indicate their general relation;

Fig. 3 is a transverse sectional view through the packet.

Referring to the drawings the invention comprises a box consisting of two parts 4 and 5 which are interengaged and locked together to enclose with a hermetic seal, one or more bandages or other surgical dressings 6. One of the parts is provided with ashoulder 7 located below its open edge so that a rim 8 is provided on this part above the shoulder. The other part is made to fit over the rim 8 and against the shoulder 7 and it is provided with an outwardly projectin flange 9 to correspond with the shoulder and abut thereagainst. I prefer to interpose a gasket of paper or other suitable material between the shoulder 7 and the flange co 9 to assist in making a tight joint. The

outer edge of the flange 9 is bent over upon the flange or beaded at 9 and the extreme edge of the bead is spaced slightly from the upstanding wall of the part 4 to provide a as groove 97 between the edge of the bead and Serial No. 513,234.

said wall. A binding tape or band 10 preferably made of soft steel is secured over the shoulder 7 and the beaded flange 9, and it is provided with a projecting end 11 by which the packet can be suspended and also to facilitate removal of the tape. This tape is formed with an interior groove 10' to receive the shoulder and flange 7 9. and then the tape is pressed snugly and tightly in place upon the shoulder and flange to securely hold the parts together.

The two parts of the box are lacquered on the outside and the tape is lacquered on both sides. Therefore, the lacquered surface of the tape will engage a lacquered surface on both parts of the box since the tape is pressed snugly and flatly against the underside of the fiat shoulder 7 and is also pressed over the bead 9 with its edge seated in the groove 9". When this bead is pressed into shape on the shoulder and the flange it will not only hold the parts of the box tightly together but it will form an air tight and Water tight seal with the gasket and the interfitting parts to protect the contents of the box and preserve them in an antiseptic and sanitary condition indefinitely.

These packets are principally used by $01- diers in thearmy and are intended for first aid use on the field of action or on the march. It is highly' desirable that a packet should be strong to resist wear and rough usage, as well as tight to preserve the contents,but it is equally important that the packet should be so made that it can be easily opened under the most adverse conditions. The present invention answers these requirements and provides a box which will properly protect and preserve the contents and which can be easily opened by tearing off the tape and separating the parts. This tape is preferably made of soft steel so that it can be easily applied and as easily removed and it is a material which has sufficient strength to perform the functions required of it as an element of this invention in an entirely satis factory manner. The end of the tape is preferablv bent back upon itself. as shown in Figs. 1 and 2 to provide greater strength and stiffness and this end may be attached to a soldiers belt by a hook or other means.

The box will be made of a size and shape adapted to receive the desired dressings which are first subjected to great pressure to reduce them to a compact size, and these 110 dressings may be put up in any approved manner for enclosure in the box. The drawings illustrate a box of a size and shape and construction which I believe, from my experience in making a great many boxes for use in the great war, will be found highly satisfactory for army use, particularly because of the very efiicient seal which, however, can be easily broken when desired. I do not restrict myself to the use of the invention in a packet of the particular size, shape and construction illustrated but reserve the right to make all such changes therein as clearly fall within the scope of the following claim:

I claim:

A box for a first-aid packet comprising two parts adapted to be engaged one within the other, one of said parts having a shoulder and the other part having a flange to abut against the shoulder, said flange having a bead on its outer face, and a tape compressed upon and enclosing the shoulder and flange and extending over said bead, said tape extending entlrely around the packet and having a projecting end forming a means by which the packet may be suspended and serving also as a handle to facilitate the removal of the tape.
