S. QUISLING BAG cLosURE NOV. 5, 1935.

Filed Deo. 4, 1933 Patented Nov. 5, 1935 UNITED STATES rjATENT OFFICE 4 Claims.

This invention relates to closure means for bags, sacks, or the like.

One object of the present invention is to provide a bag closure, very easy to place upon a bag, providing a positive closure which will not harm a bag in any way.

Another object of the invention, is the provision of such a closure which, tho simple to apply to a bag, when applied, is proof against accidental displacement. Y

The invention also contemplates the provision of a closure which in itself forms a hand grip to facilitate carrying the bag from place to place.

Still another object of the inventionY is to provide a bag closure which, by the nature of its construction, may be manufactured so cheaply, that when it has served its purpose it may be discarded with but aninconsequential monetary loss.

Altho a preferred embodiment of the invention is shown in the drawing and hereinafter described, it is understood that changes may be made in its construction without departing from what is claimed.

In the drawing:-

Figure l is a perspective View of a closure constructed in accordance with the invention, and shown applied to a bag;

Figure 2 is a fragmentary perspective View of the under surface of the closure member;

Figure 3 is an end View showing the manner in which the bag is folded over the locking strip and inserted into the bag closure;

Figure 4 is a transverse section of the device locked in place upon the open end of a bag;

Figure 5 is a view of the blank from which the closure is formed;v

Figure 6 is a perspective view of la modification, and;

Figure 7 is a perspective view of an added modiiication.

The invention, in its present embodiment, consists of a closure member |,1and a locking stripV 2. The closure member, as is shown in Figure 5, is formed of a sheet of rigid, or semi-rigid material, such as sheet metal, Celluloid or the like, and is adapted to be cut and formed into shape in a single operation.

In the formation of the closure, a rectangular opening 3 is cut out near each end of the-blank sheet, anddown the center of the blank, connecting the openings 3, is a zig-Zag cut d, which when the material is bent downward upon the dotted lines 5, of Figure 5, form teeth 6 to engage the bag and prevent any possbility of accidental displacement of the closure. 'Ihe end portions of the blank-are bent up along the dotted lines 'l to form end anges 8.

In Figures 6 and '7, are shown modified forms of downturned bag gripping means to be used 5 on bags which might become torn by the use of the teeth 6. Figure 6 shows a straight downturned flange 9, while in Figure 7, the ange is formed with corrugations as at l0.

In'applying the closure to a bag, the locking 10 strip 2 is held in a vertical position, and the top of the bag folded over the strip, as in Figure 3. The strip carrying the folded over bag top is then inserted between the downturned flanges, carrying teeth 6, up into the openings 15 3, Where the locking strip is given a quarter turn and dropped upon the lower side of the opening. The locking strip being of greater width than the space between the downturned flanges prevents the bag from dropping out. catch the sides of the bag and prevent any possibility of the bag slipping around the locking strip. The ends of the locking strip may be turned down, as is shown in dotted lines in Figure 1, if desired, thus locking the strip against 25 v longitudinal movement within the closure.

I-Iaving thus described the invention what I claim is:

l. A bag closure comprising a closure member with upturned end flanges having openings therein, the body portion of the closure having a slot along its middle connecting the openings in the end flanges, said slot being defined on two sides by downturned flanges carrying bag gripping means, and a locking strip adapted to be inserted with a bag into the slot and turned on its center axis within the confines of the openings in the end ilanges to lock the closure upon the bag.

2. A bag closure comprising a slotted member with upturned end flanges having relatively larger openings than the width of said slot, said slot being deiined on both sides by downturned flanges with irregular surfaces to Contact the bag, and a locking strip member to be inserted with the fold of the bag into the slot of the first member which second member when turned on its center aXiswhen thus placed, locksthe bag in the closure and is prevented from slipping out by being held in the openings of the upturned flanges 50 of the rst member.

3. A bag closure comprising a member of flat rigid material having a longitudinal slot down its middle and transverse slots in upturned end flanges, a locking strip member to be placed With- 55 The teeth 20 in the fold at the mouth of a bag to be closed, said fold to be brought thru the longitudinal slot of the rst member and the second member turned upon its center axis and the ends of said second member engaged in the transverse-slots of the flanges of the rst member for the purpose specified.

4. In a device of the character described, a at slotted locking closure member to slip over the folded mouth of a bag, said member having end flanges containing openings for passage and engagement of the ends of a second strip member which second member is placed within the fold of the bag, and when in position turned on its center axis and thus locked for the purpose specified.

SVERRE QUISLING.
