Patented Dec. 24, 1929 UNITED STATES PATENT OFFICE WILLIAM H. SCHAEFER, 0F GREAT NECK, AND GUSTAV ECKERT, OF BRONX, NEW YORK ACLIP OR FASTENER Application led March 19, 1928.

This invention relates to improvements in clips or fasteners for securing the bendable flap of a cardboard box in closed position.

The primary object of the invention resides in a clip or fastener for the attachment to the operable flap of a cardboard box after the same has been initially opened by the usual cutting operation of one of the end walls, to temporarily hold the flap in closed position when not in use to preserve the contents of the box and prevent accidental spill ing thereof.

Another object of the invention is to provide a clip for retaining the hinged flap or lid of a cardboard box or carton in a closed position, and which includes two sets of clamping jaws respectively disposed at right angle with respect to each other, one set serving to receive the flap to support the clip thereon while the other set of jaws will automatically ride down overl the edge of one of the side walls upon closing of the flap, for clamping engagement therewith to hold the flap in a closed position.

A further object of the invention is the provision of a clip of the above kind which is constructed of a single piece of resilient metal bent to provide two sets of right angularly disposed jaws, which makes the article simple of construction, and accordingly inexpensive of manufacture.

lith these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed, out in the appended claims, and are illustrated in the accompanying drawing, in which z- Figure 1 is a fragmentary perspective view of a carton or box with the openable flap or lid in a raised position with our improved clip in position thereof.

Figure 2 is a similar view with the flap in a closed position.

Figure 3 is an enlarged vertical transverse sectional view on the line 3 3 of Figure 2.

Figure 4 is a perspective view of the clip per se.

Referring to the drawing by reference Serial No. 262,697.

characters, the numeral l0 designates our lid fastening clip in its entirety which is constructed of a single length of bendable resilient wire. The length of wire is bent approximately midway between its ends into sets of right angularly disposed clamping jaws 11 and 12. These jaws are formed by bending the ends of the wire into two separate coils, each having two convolutions which constitute the jaws of each set as the part to which the jaws are adapted to be clamped are inserted therebetween.

The jaws 11 and 12 have outwardly flared portions 13 and 111 respectively to provide enlarged mouths to facilitate of the easy and free insertion of the parts to which they clamp. The inner surfaces of the jaws of the set 11 are milled or roughened as at 15 to increase the friction between the same and the lid of a box to which it is adapted p to be attached.

ln the drawing, we have shown our invention as applied to a cardboard box or carton 16 which may contain any foodstuff or substance as are generally placed in packages of 7 this kind and whereof the contents are likely to be used from time to time before completely empty. This is true of such food stuffs as breakfast cereals, flour, crackers and the like, and such other substances as soap flakes, cleaning powder and therlike.

It is the usual practice to break open one of the ends of the box by cutting about three of the sides and then bending the end back such as shown at 17 in Figure l of the drawing. This end wall may now be termed a swingable or hinged lid which is intended to preserve the contents of the box when swung' to a closed position, but the same will not remain fully closed under its own weight. However, by applying the clip 10 to the lid by inserting the lid between the set of jaws 11 the same will engage opposite sides of the lid and will securely .support the clip in position. The clip is of course applied when the lid is in an open or partially open position, whereupon closing of the lid, the set of jaws 12 will ride down over opposite sides of one of the side walls of the box and clamp therewith. The

clamping action between the jaws 12 and the wall of the box is such as to hold the lid in a closed position to preserve the contents of the box when not actually in use, but allows the lid to be easily swung to an open position when desired. The jaw 12 being provided with an enlarged mouth portion 14, facilitates of the easy movement of the same over the side wall of the box when the cover is moved to a closed position.

Although we have shown and described, a clip made of a single length of wire -bent into sets of right angularly disposed convolutions which serve as clamping jaws, it will be appreciated that the device may be made of flat bendable metal in separate pieces joined together.

While we have described what we deem to be the most desirable embodiment of our invention, it is obvious that many of the details maybe varied without in any way departing lfrom the spirit of our invention, and we therefore do not limit ourselves to the exact details of construction herein set forth nor to anything less than the whole of ourinvention limited only by the appended claims.

What is claimed as new is l. A fastener of the character described comprising a single length of resilient wire havingits ends bent into two separate coils, the axes of which are disposed atgright angles to each other, the convolutions of the respective coils constituting clamping jaws.

A lid fastener comprising ya single length of resilient wire having its ends bent into two separate coils, the axes of which are disposed at right angles to each other, the convolutions of the respective coils constituting clamping jaws, the outer portions of the convolutions being flared outwardly to yprovide enlarged mouths for theeasy insertion of the jaws over the parts to be held thereby.

In testimony whereof we hereby affix our signatures.
