particularly when it is to I have v a bag 2 of the type just described has its top end attached to one of the flaps l6, which serve to close the top end of a collapsible box of the type which comprises two side members is and 20 and two end members 22 and 24 made from a single sheet scored to permit bending, having its side edges fastened together to form the fourth box corner cover .fiam i6 and. 28 and end'cover flaps 28 and 30 and side bottom flaps 82 and 38 and end bottom flaps 3B and 38, the top end of the bag being so attached to the end flap is that when the flap is in open position, as shown in Figure 1, the valve 12 will be in convenient position to receive the nozzle Hi of the filling machine, I will obtain a combined bag and box package in which, when the bag has been filled to the usual extent and the nozzle iii withdrawn, the top flaps of the package can be folded into closed position, as partially shown in Figure 5, and the box sealed with a minimum of waste space between the box and the enclosed other words, a box closely fitting the bag can be utilized with the bag, thus preventing the shucking motion experienced with the boxes now used with bags-of this type, which results in a tendency to pump air into and out of the box and also into and out of the bag, and also results to both the box and the bag.

The top of the bag 2 may be attached cover fiap It in any suitable manner, as, for example, by cementing, sewing or stapling, one of the most convenient methods of securing the top of the bag 2 to the cover flap It being by means of staples l driven through the reinforced top end of the bag and through the cover flap i8 and clenched on the cover flap. As shown, these staples may, if desired, be driven at a slight inclination to the line of stitching l0 so that the legs of the staples straddle the stitching l0, thus making a very secure attachment of the bag top to the cover flap It. The position, in respect to the width of the cover flap ii, of the line of depend somewhat upon the position of the line of stitches III with respect to the valve I2, it being important that the valve flap is in the position shown above the top edge of the box proper, so that it will be in position for convenient insertion of the nozzle ll.

As shown in Figure 2, in a box or thetype illustrated in Figures l to 6 inclusive, which has sides of considerably greater width than its ends, when the cover flap i6 position shown in Figures 1 and 2, will be substantially on a line with the bottom of the closed box or with the score lines determining the bottom flaps of the open bottom box the box be is in the open made more nearly square in cross-section,

As hereinabove pointed out, however, the invention is equally applicable to combined bags and boxes used in packaging other materials, such as gelatin, granulated sugar, pop-corn, molding plaster, etc., in which other types of bags than the Bates valve bag are u Figures '7 and 8 show the invention applied to a combined bag and box in which a bag 2 of transparent material, such as Cellophane, is employed.

In the form of the invention shownin Figures 7 and 8, the bag 42, which, as above suggested, may be of Cellophane, of the heat-sealing type, for example, has its filling end normally comfiap it" shown in Figure 7, that top is attached to the from the upper end,
