VALVE BAG CLOSURE Application filed May 4,

This invention relates generally to ba valves, and has for its object the provision an improved type of such valve provided with a more "effective closurethan is customarily employed. It has been customary to provide a bag with an opening for filling purposes, and to rely upon the outward pressure of the material in the filled bag to close such opening. The present invention provides a valve wherein a positive closure is effected, independently of the pressure or weight of the contents of the bag. The invention will best be understood by reference to the accompany- 1 ing drawings, wherein is illustrated the present preferred embodiment thereof, and in which Figure 1 is a side elevation of a cloth or paper bag, partly broken away in order to show in section a valve embodying the invention.

Figure 2 is a vertical section taken on the line 22 of Figure 1.

Fi re 3 is a horizontal section taken on the line 33' of Figure 2.

Figure 4 is a detail side elevation of the valve, a portion thereof being shown as broken away in order to more clearly illustrate the construction employed.

'Like reference characters indicate like parts throughout the drawings.

Referring to the drawings tFig- 4),. the valve, designated generally by the reference numeral 1, comprises a paper sleeve, open at both ends and adapted to be inserted in an opening left in the upper edge of a paper bag 2, and to be attached to the walls of said bag. The sleeve is provided with two upwardly-extending flaps 3 and 4;, which are 40 folded outwardly to embrace a portion of the upper surfaces of the bag walls.

These flaps are to be attached to the walls of the bag by suitable adhesive material. the positions of the several parts being indi" cated in Fig. 2. Embracing the sleeve near the bottom thereof is a resilient metal band. 5. retained in position upon the sleeve by means of two bottom flaps, 6 and 7. which are folded upwardly and attached by' adhesive material to the band itself, to the outer walls 1929. Serial No. 360,352.

of the sleeve, or to both such band and outer walls.

The mode of operation of the device is as follows: with the valve installed in thebag (which is closed on either side of the valve as by stitching 8), a filling nozzle (not shown), leading toa supply of material, is passed throughthe valve and into the bag proper, During this process, the metal band 5 and the walls of the sleeve are distended after the manner indicated by dotted lines in Fig. 3. After the bag is filled, the nozzle is withdrawn from the valve, and the resilience of band 5 restores it to the normal position of parallelism of its two sides, thercby efiectually and positively closing the valve and insuring against egress of material contained in the bag.

The valve is simple in construction, it may be economically and easily attached to a bag, it readily opens when a nozzle is passed therethrough, and it closes with certainty upon the withdrawal of the nozzle.

I have described what I believe to be the best embodiment of my invention. I do not wish, however, to be confined to the embodi ment shown, but what I desire to' cover by letters patent is set forth in the appended claims.

I claim:

1. In a valve bag, in combination, a body portion forming the bag structure, a valve sleeve extending into the bag, and a spring clip surrounding the inner end of said sleeve, normally maintaining said inner end closed but adapted to be distorted by a spreading element thrust into the sleeve to permit fill ing of the bag.

2. In a valve bag, in combination, a body portion forming the bag structure, a valve sleeve extending intothe bag. and spring means connected to the inner end of said sleeve. normally maintaining said inner end closed but adapted to be distorted by a spreading element thrust into the sleeve to permit filling of the bag.

3. In a. valve bag, in combination, a body portion forming the bag structure, a valve sleeve extending into the bag, and a spring normally maintaining the inner end of the valve sleeve in a 'flat closed condition but yieldable to ermit the sleeve Walls to be spread apart by pressure exerted from Within the sleeve.

4. In a valve bag, in combination, a body portion forming the bag structure, a valve sleeve extending into the bag, and a spring normally maintaining the wallsof the inner end of the sleeve pressed together but adapted to be spread by pressure exerted from Within the sleeve and effective automatically to press the Walls of the inner end of the sleeve together upon the pressure from within the sleeve being relieved.

5. In a valve bag, in combination, a body portion forming the bag structure, a valve sleeve extending into the bag, and means imbedded in the sleeve at the inner end thereof and automatically maintaining the inner end of the sleeve in a flat closed condition but adaptedto be spread by pressure exerted from Within the sleeve to permit filling of the bag.-

In testimony whereof I have aflixed my signature ,to this specification.

HARRISON R. WILLIAMS.
