PAUL ELLIOTT CREWS, OF DURHAM, NORTH CAROLINA, ASSIGNOR TO. GOLDEN BELT MANUFACTURING COMPANY, OF DURHAM, NORTH CAROLINA, A CORPORATION OF NEW JERSEY.

BAG-CLOSURE.

Application filed August 4, 1917.

To all whom it may concern:

Be it known that I, PAUL ELLIOTT CREws, a citizen of the United States, residing at Durham, in the county 30f Durham and State of North Carolina, have invented new and useful Improvements in Bag-Closures, of which the following is a specification.

The present invention relates to an improved bag closure and method of closing and sealing bags, and is designed particularly for those bags of fibrous material now generally used for packing granulated tobacco, although it will be understood that the invention is not confined to this particular use, as it may be applied to any container formed of flexible material for carrying various commodities.

The invention is designed to provide a closure for and method of closing bags, which will reduce the cost of closing and sealing the bags to a minimum; give a smooth, flat top to the bag; and provide a sealed top which when initially opened will present the contents of the package to the consumer without the necessity of opening up the pull strings which are now commonly used.

In the drawings herewith I have illustrated the various steps in theformation of this closure, and in said drawings:

Figure 1 is a view in perspective of a bag, the top of which is fully open and before any of the closing and sealing steps have taken place.

Fig. 2 is a perspective view of the top of a bag with the end folds of the closure made.

Fig. 3 is a perspective view of the bag, one of the side folds having been made.

Fig. 4 is a perspective view of the bag, the final side fold having been made.

Fig. 5 is a view of the completed bag with a sealing label or stamp in position.

In bags of this character, it is customary to form them of fabric and provide the neck of the bag with strings, which, after the bag is filled, are drawn tightly so as to close the neck of the bag. This practice, which has long been followed, results in bunching the fabric of the neck centrally of the bag, and over this neck the sealing label or revenue stamp passes. With the old arrangement, some difiiculty is experienced in applying the sealing label or stamp, and furthermore, it is necessary for the consumer in opening the package to untie the draw i Specification of Letters Patent.

strings, which are usually knotted together, and then loosen the neck so as to open the bag, and as these strings are drawn and knotted very tightly, initial opening of the bag is sometimes difiicult.

In the construction devised by me, these difiiculties are overcome so that a smooth, flat, well-shaped top is formed, over which the sealing label or stamp may be readily and smoothly applied, and in which the ini tial opening of the bag is readily accomplished, as the consumer has only to unfold the closure without opening up a bunch or drawn neck. After this initial opening,

the bag may be used in the ordinary way and closed by means of the draw strings.

Referring to the drawings by numbers, like numbers indicating -like parts in the several views, 10 designates a bag of any suit-able material having the open top 11 with the draw strings 12 laid in the string pocket formed at the neck of the bag as is customary.

The essential thing in the method of closing and the closure invented by me is the inturning of the drawing strings and the neck of the bag in unpuckered condition, and while this may be accomplished in a varied number of ways, it is preferably done in the manner hereafter set forth.

The initial step in forming the closure is preferably the inturning of the end folds 13 along the dotted lines shown in Fig. 1, the inturned position of these folds 18 being shown in Fig. 2 so that they lie flat against the top of the contents of the package with the draw strings 12 laid fiat in the position shown in Fig. 3. The next step in efiecting the closure is to inturn the side flap 14 as shown in Fig. 3, the flap 1 1 folding down flatly over the inturned folds 13 and the draw strings 12.

The next step in the formation of the closure is the inturning of the side fold 15 as shown in Fig. 4, this being folded flat upon the first side fold 13, and giving a comparatively fiat, smooth top, as shown.

The flat, smooth surface thus formed may be sealed or secured in any suitable manner, either by pasting the flaps themselves in place, by mechanical fastening means, or, as herein shown, by the use of the sealing label or stamp 16, (Fig. 5) which may be conveniently secured over the top of the bag, the closure described forming a relatively smooth and firm closure to which the stamp will readily adhere, and the ends of the stamp may then be wiped downwardly along the sides of the package, as shown in Fig. 5.

This closure and method of closing gives a package which is of uniform size and shape at its ends, eliminates bunching and compression of the package by the draw strings so that a smooth surface for the sealing stamp or label is provided, and as will be obvious, eliminates all projecting corners or ends as the package is turned out from the packing machine.

The consumer has but to break the sealing label or stamp, open all folds, as heretofore described, and the contents of the package are accessible. At the same time all of the advantages of the old packages are retained in so far as the draw strings are concerned, for after he initial opening, the consumer may utilize the draw strings in the usual manner to close the neck of the ba It will be understood that Variations in the manner of folding and disposing of the various folds and the draw strings may be made in effecting this closure without departing from the spirit of the invention, and, furthermore, while I have shown two draw strings as is customary in this type of container, it is equally applicable to bags in which a single draw string is used.

I claim 1. A closure for strung bags having its end folds and draw strings in loose untied condition inturned so as to lie flat upon the top of the package, its side folds inturned and folded fiat upon said end folds and draw strings, and means to secure said inturned and flattened folds in position.

2A closure for strung bags having its end folds and draw strings in loose untied condition inturned so as to lie flat upon the top of the package, its side folds inturned and folded fiat upon said end folds and draw strings, and a stamp or label to hold said flattened folds in position. 3. A closure for strung bags having its end folds and draw strings in loose untied condition inturned so as to lie fiat upon the top of the package, its side folds inturned and folded flat upon said end folds and draw strings, and a revenue stamp to hold the inturned and flattened folds inposition.

-il. A closure for strung bags having opposite folds of its unpuckered top and the draw strings in loose untied condition inturned so as to lie flat uponthe top of the package, its other folds inturned and folded at upon said first-named folds and draw strings, and means to hold the inturned and flattened folds in position.

5. A closure for strung bags having the draw strings, in undrawn condition, inturned so as to lie flat upon the top of the package, the folds of the unpuckered top inturned upon said draw strings, and means to hold the inturned and flattened folds in position.

In testimony whereof I have hereunto set my hand.
