BOX CLOSURE.

Application filed January 28, 1925.

1 0 all whom it may concern:

Be it known that I, HARRY L. FnLLowns, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improven'ient in Box Closures, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to box closures.

It relates more particularly to closure fasteners of the type employing a cord and button to hold the closure shut.

Heretofore it has been a common practice to anchor both ends of the'cord directly to the shank of the button, one end being initially wrapped around the shank. The other end is also wrapped around the shank of the button after the cord has been passed through the hooks or eyelets of the closure and drawn taut. Such an arrangement is objectionable because the bulk of the necessary wrappings or turns of the cord about the shank of the button'prevents the head of the button from lying tightly against the wall of the box. Also, the initial wrappings or turns of the cord interfere with the winding and unwinding of the final or tying wrappings or turns, with the result that the cord wears rapidly and the head of the button may be damaged or destroyed if the same is made of weak material, such as paper or thin fibre,materials quite commonly used to form the button heads.

One of the objects of this invention is to provide an improved box closure.

Another object is to provide a closure in which the above objections are overcome.

Another object is to provide a closure fastoner wherein only one end of the cord is anchored directly to the shank of the button.

Another object is to provide a cord anchorage which is particularly adapted for use with boxes made of relatively weak material, such as cardboard.

Another object is to distribute the load of the cord anchorage over a relatively large area of the box wall.

Another object is to provide a closure fastener which is simple, reliable and inexpensive.

Other objects and advantages will hereinafter appear.

An embodiment of the invention is illus- Serial No. 4,660.

Fig. 1 is a perspective of a box provided with the improved closure fastener;

Fig. 2 is an enlarged section on the line 22 of Fig. 1; and

Fig. is an enlarged section on the line 33 of Fig. 2.

The box chosen to illustrate the application of the closure fastener has side walls 5, end walls 6, a bottom 7, and a top closure composed of two hinged sections 8. The box may be made in various ways, such, for example, as from a single piece cardboard blank which is folded into the desired shape. In order to facilitate the lacing of the fastener cord, the adjacent corners of closure sections 8 are made readily foldable along the diagonal lines 9 to form corner flaps 10. Each flap 10 is provided with a cord lacing eyelet 11.

The closure fastener cord 12 is adapted to be anchored at suitable places on the box, for example, at each end below the line of the adjacent edges of closure sections 8. The end of the box is provided with two

small holes

13 and 14. Hole 13 is for receiving the shank of the cord anchoring button which comprises a metal rivet 15 and a disc-like head 16 of metal, fibre, paper, or other desired material. The shank of rivet 15 passes through the central opening of a reinforcing plate in the form of a disc or washer 17 and is upset to tightly hold the washer and button head 16 in place. Plate 17 is provided with one or more holes 18 which may be brought into register with hole 1A so that cord 12 may pass there through from the outside to the inside of the box. Only one of the holes 18 is used, but by stamping out the washers with several holes, the proper registry thereof with the hole in the box is facilitated.

One end of cord 12 is passed through the registering holes 14: and 18 and is anchored on the inside of the box by making a large knot therein, or, preferably, by tying a ring 19 thereto, so as to form an abutment to engage plate 17. The free end of the cord is passed through the eyelets 11 in closure sections 8 and, when the closure is tightly shut, the taut cord is wrapped about the shank of the anchoring button behind its head 16.

In the improved fastener only one end 110 of the cord is wrapped about the shank of the anchoring button. The other end is anchored by the washer which distributes the load from that end of the cord over a considerable area of the box wall away from the shank of the button. The washer also distributes the load of the button to which the other end of the cord is anchor-er. The place on the cord where the initial anchorage occurs may be easily and quickly varied by changing the position of ring 19. In the event that one cord becomes worn, substitution of a new cord is readily made, because its initial anchorage is not permanentv The elimination of the cord wrappings or turns to produce the initial anchorage reduces the bulk of the cord behind the button head and the same may be set closer to the wall of the box. Furthermore, there is not the objectionable overlapping and wedging action between the initial and final turns of the fastener cord which obtains when the button serves as the anchon.

age for both ends of the cord.

I claim:

1. A closure fastener for boxes and the like comprising a button for inountingon the outside of the box and having a shank to pass through the wall of the box, a cord anchorage secured against the inside oi the box bythe button shank and serving to disand adapted to pass through openings in the anchorage and the box wall at a point removed from the shank so that its outer end may be wound about the shank of the button 011 the outside of the box.

2. A closure fastener for boxes comprising a button whose shank passes through a wall of the box, a plate interiorly of said box for receiving the shank of the button and distributing the load therefrom to the Wall of the box, and a cord .passin through registering openings in the wall or the box and plate at a pointremoved from the shank and having an abutment toengage the plate and thereby anchor one end thereof, the cord cooperating with the closure to hold the same shut and having its other end anchored by the shank of the button.

In witness whereof, I hereunto subscribe my name this 24th day of January, 1925.
