The tongue is preferably made by the slits 11. These flaps are foldable together no to provide the top wall of the container. Similar flaps are formed on the other end of the blank to form the bottom wall of the container, but, to

main body of the flap by the curved slit 13. By-

providi-ng a crease 14 across the uncut portions between the tongue and flap the former is hingeably secured to the latter. A pair of spaced creases or scores 16 are provided to connect with theends of the hinge crease 14 and extend across the tongue 12 to foldably divide the same into a central and two end portions, so that the tongue may be folded to form a spout. A smaller tongue portion 17 is also provided, and is hinged on the flap 7 at the scoring 18, so that by depressing this tongue suitable means, such as the tip of the finger, may be inserted under the edge of the larger tongue 12 to bend it outwardly from the flap.

Formed in the side flap 8 adjacent the edge which abuts the end flap '7 is a removable porformed by printing on the surfaces of the flapswith a, heavy ink, preferably an ink which presents a glazed surface when set, so as to prevent the adherence thereto of the glue used in securing the flaps of the container together.

In the formation of the container, as best shown in Figures 5 and 6, the end flaps 6 and 7 are bent inwardly so as to lie at right angles to the side walls of the container, and the side flap 8 is bent downwardly to lie on the end flaps; these elements being secured together by a layer of suitable adhesive 26. Due to the glazed surface presented by the ink shield 23 only the unshielded portions of the end flap '7 will be secured to the underside of side flap ,8, so that the adhesive will not interfere with the movement of the tongues 12 and 17. The other side flap 9 is now bent to overlie the flap 8; these elements being secured together by a layer 2'7 of suitable adhesive. As in the previous instance, only the unshielded portions of flap 8 are secured to the underside of the flap 9; the glazed surfacepresented by the shield 24 effectively resisting the adherence of the adhesive. It will be seen that the sections 19 and 21 are adhesively secured together to form a unitary cut-out, the upper section 21 of which is adapted to lie on the ledge 28 bounding the smaller section 19; it being noted that the upper section 21 is prevented from adhering to the surface of the ledge by the ink shield 24.

The process of opening the container is best illustrated in Figures 2 to 5. The cut-out formed by the adhesively united sections 19 and 21 is seized at the top edge of the container and is torn from the side flaps 8 and 9 to expose the tongues 12 and 17, as shown in Figure 3. The tongue 1'7 is now pushed downward or depressed so as to enable a suitable implement or the tip of the finger to be inserted under the edge of the tongue 12. As shown in Figures 4 and 5, the spout form ing tongue 12 is now drawn forward thru the aperture 31 provided by the absence of sections 19 and 21.

The side portions or wings 32 of the tongue 12 lying under the side flaps are held back as the central portion of the tongue is pulled thru the aperture, so that the side portions 32 are forced to swing inwardly as they slide out past the edges of the aperture, thus causing the tongue to fold along the scoring 16 to provide a trough shaped spout. It is to be noted that the shape of the removable section 19 is such that it provides the shoulders 30 when removed. These shoulders provide a base for' the spout when it is in the extended position. Figure 4 shows this feature. After the desired amount of the contents of the container has been removed the spout may be returned to the position indicated in Figure 3, thus affording protection for the contents against the entryof dust Pr other foreign matter into the container.

As best shown in Figure 6, the area indicated by the stippling 23 on and about the tongue 12 may be recessed slightly to provide a space 33 between the end flap 7 and the underside of the side flap 8. This spacing of the parts prevents the adhesion of that portion of the securing layer 26 overlying the recess. Either the paint shield or the 105 recess idea may be employed, or both may be used 7 together.

In packaging granular or other pourable materials in containers provided with removable portions to permit of pouring the contents thereof, considerable difliculty is experienced in .preserving the seal of the package intact until it reaches the consumer. Extensive handling of the containers increases the possibility of accidental puncture of the package by dislodgment of the section covering the pouring aperture, with the result that a portion of the contents is lost and the package is rendered unmarketable. The pouring spout embodied in my container overcomes this difilculty by the provision of an improved method of forming a protecting cut-out, so as to resist all but the correct method of dislodgment.

Furthermore, the provision of means for shielding the working parts of the spout during formation of the container precludes the possibility of the adhesive used therein interfering with the function of the spout. It is further to be noted that all the parts of the spout as well as the means for its protection are formed from material that is already in the container, and that all maybe made at the same time the container blank itself is stamped out and printed.

I claim:

1. A container comprising a wall panel having 135 a portion thereof foldable to provide a spout, a second panel overlying and adhesively united to the first-mentioned panel and having a portion thereof removable independently of the spout to provide an aperture thru which the spout may extend, a third panel overlying and adhesively united to the second-mentioned panel and having a portion thereof removable to provide an aperture in register with the aperture of the second panel, the removable portion of the third-mentioned panel being larger than the removable portion of the second panel so'that the former seats on the portions of the panel surrounding the latter, and means for preventing the adhesive from adhering to the foldable spout portion and the portions of the second panel on which the removable portion of the third panel seats.

2. A container comprising a wall panel having a portion thereof hingedly connected thereto and foldable to provide a spout, and a second panel overlying said first-mentioned panel and having a portion thereof removable independently of the spout to provide an aperture through which the spout may extend, said removable portion terminating at an edge of the panel adjacent the spout and being defined by a line of weakened attachment shaped to produce shoulders at opposite sides of the spout adjacent its hinge when the portion is removed.

3. A container comprising a wall panel having a portion thereof foldable to provide a spout, and a second panel overlying said first mentioned panel and havinga portion thereof removable independenly of the spout to provide an aperture through which the spout may extend, and a third panel overlying the second-mentioned panel and having a portion thereof removable with the firstmentioned removable portion to provide an aperture in register with the aperture of the second panel, the removable portions extending to corresponding edges of their respective panels.

4. A container comprising a wall panel having a portion thereof hingedly connected thereto and foldable to provide a spout, and a second panel overlying said first-mentioned panel and having a portion thereof removable independently of the spout to provide an aperture through which the spout may extend, and a third panel overlying the second-mentioned panel and having a removable portion to provide an aperture in register with the aperture of the second panel, the removable portions extending to an edge of the container to facilitate removal thereof and one of
