CONTAINER Filed April 13, 1934 3 Sheets-Sheet 5 3Q f V Patented Nov. 29, 1938 UNITED STATES PATENT OFFICE 2.138.700 con'rsnvna George K. Hoff, 3d, Philadelphia, Pa. Application Aprll13, 1934, Serial No. 220,392 14 Claims. (0i. ass-23) This invention relates to a container and more particularly to a paper or cardboard container for liquids.

It is the purpose of this invention to provide a simple, strong and inexpensive container for liquids, such as milk, fruit juices, and the like, which may be easily carried and readily opened for the dispensing of its contents.

The container in accordance with this invention will desirably be made of heavy paper or cardboard, and its construction will best be shown by reference to the accompanying drawings, in which:

Figure 1 is a plan view of the unfolded blank forming the principal portion of the container Figure 2 is a plan view of the unfolded inner reinforcement or saddle for the container.

Figure 3 is a plan view of the unfolded outer reinforcement or saddle for the container.

Figure 4 is a perspective view showing the manner of folding the blank shown in Figure 1 to form the container.

Figure 5 is a perspective view showing the container completely folded and with the inner saddle in place.

Figure 6 is a perspective view from another angle of the structure shown in Figure 5.

Figure '7 is aperspective view showing the container partially folded for sealing and with the outer saddle in place.

Figure 8 1s a perspective view of the completed container.

Figure 9 is a diagrammatic view of the top of the container showing the manner of opening.

Figure 10 is a perspective view of a portion of the container showing the container as opened to dispense its contents.

Figure 11 is a perspective view of another modification of the container in accordance with this invention. 3

Figures 12 and 13 are perspective views of the top portion of this modification showing different stages in the closing and sealing thereof.

Figure 14 is a perspective view of this modification of the container, showing it opened to dispense the contents thereof. a

with reference to the drawings,.the container in accordance with this invention may be formed V by superposing inside saddle 2, upon section A--A of blank i, and then folding these two pieces in the manner'shown in Figure 4, in which the lettered sections of the'biank refer to the same sections as shown by the dotted lines in Figure 1, to form a rectangular container as shown in Fig--v

ures

5 and 6. It is, of course, immaterial which of the sections 13 in Figure 4 overlies the other. .By this folding the two slots 3 in blank I have been brought into registration, and now the outside saddle 4, which has in it a slot of the same dimensions covered by a transparent closure '5, is placed around the container, as shown in Figure 7, so that the slots 3 are covered by the trans- Parent closure 5 through which the contents of the container may later be observed. This outside saddle also serves to hold together and reinforce the folds at the bottom of the main portion of the container, and has a flap 9 extending above the container to effect closure as hereinafter described.

The separate portions of the container and the various folds thereof are now adhered together throughout their contacting surfaces and accordion pleats 6 to facilitate closing and sealing are formed, as shown in Figure '7. in any desired manner, as for example. by dipping the container in any suitable adhesiveyas molten parailln wax, and then pressing in a suitable die which will form the accordion pleats, and will also. desirably, round the bottom corners l to give greater strength and make the handling ofthe container easier. The paraflln wax will also serve to make the container impervious to liquids. In many cases it will be desirable to apply an adhesive, as

a suitable paste, between all contacting surfaces as the various parts are placed and/or folded into position, and then apply a coating of wax. as by dipping as described above; This adhesive can be best applied by coating the shaded sections and also the reverse sides .(not shown) of sections E of blank I and by coating one side of

blanks

2 and 4 with the adhesive before assembling the container.

The container is now complete and ready to be filled and sealed. It may, of course, be sold in this form to be filled by the purchaser, or it may be filled bythe manufacturer of the container. In any event the container will be'i'llled with the desired amount of liquid. as for example, milk, and then the top portions 8 and 9 of outside saddle 4 of the container will be brought together and flap 9 whichextends above the top of the container willbe folded over and adhered to portion 8 as shown in Figure 8. Desirably the sealing will be strengthened by stitching Hlwhich securely closes the container, and the entire container will again be dipped in molten wax to close all small apertures. It will be noted that the completed and filled container may be easily handled by grasping the top portion 9 as a handle, that it is impervious to liquid, and that t the amount of liquid contained, and in the case modified form will desirably have a rectangular base with a length .of, for example, twice its width, although it obviously may have any desired dimensions. The outer reinforcing saddle I8 will desirably cover the narrower sides of the container and will .not extend across the top of the container. w

This modified form of container in accordanc with this invention is designed to be equipped with ,a pouring device ll of known design fitted in opening l3. The pouring device consists of a metal spout rotating in a supporting flange, which is positioned between the container side-wall and the outer saddle l8 so that the spout swings through. the opening l3. When closed, as shown in Figure 13, the pouring device seals the opening, and when opened, as in Figure 14, serves as a spout from which to pour the liquid contents of the container.

The top of this modified form of container is closed and sealed by folding portions l4 and 15 of the container, together with the corresponding side-wall portions, as shown in Figure 12, to form a fold having an upright rib as shown in Figure 13. This rib is then rolled tightly upon itself, as shown in Figure 14, to seal the container and to form a convenient carrying portion l6 for handling the container. The entire container is then dipped again into molten paraffin, which seals all apertures, holds the pouring device H in closed position, and. prevents the rolled handlemember I6 from unrolling.'

It will be appreciated that, while the container in accordance with this invention has been described as constructed from heavy paper or cardboard, the use of any flexible material is contemplated, and that the material used in construction may be naturally impervious to liquids, or .may be'made so by any known process, since the use ofa wax for such a purpose is described only byway of illustration and example. Likewise any suitable adhesive may be used in place of wax in the construction of the container in accordancev with this invention.
