and particularly to cartons adapted forthe packaging of food stuffs such as dry cereals and the like.

It is common practice, in the packaging of dry cereals and like products, to provide an outer container or box of light weight fiberboard or heavy stifi paper and an inner liner of relative- 1y moistureproof material such as waxed paper or the like. The inner liner serves to exclude moisture and thus keep the contents fresh and this inner liner is frequently formed as a unit by itself; and filled with cereal which is sealed therein by special packaging machinery.

The outer container, which may be blanked out by means of punch presses and special dies, may now be folded up in position to enclose the filled liner and the ends folded down and glued, all by means of other specialized machinery.

Packages of this nature may be opened by the consumer in anyone of several ways, the most common being to pry open theseveral flaps of the lid or to cut the top edge of the box on at least three sides to permit the top to be raised.

The inner liner may then be unsealed or torn is the provision of an improved, carton or package especially adapted for dry cereals.

A further object of my invention is the provision of an. improved lid or closure member for packages. 7

Another feature and object of my invention is the provision, in a package or carton, of means for simultaneously opening both the outer container and the inner liner thereof.

Another primary object of my invention is, the provision, in a carton of this nature, of means providing an improved pouring spout.

A still further feature and object of my invention is the provision, in combination with a pouring spout, of means for facilitating the opening or tearing of the inner liner.

Other and further features and objects of theinvention will be more apparent to those skilled inthe art upon a consideration of thev accom- 9 Claims. (01.229-17) panying drawings and following specifications, wherein are disclosed several embodiments of the invention, with the understanding, however, that such changes may be made therein as fall within the scope of the appended claim-s, without departing from the spirit of the invention.

In said drawings:

Figure 1 is a view in perspective of a package constructed in accordance with a preferred embodiment of my invention and illustrates, in particu-l-ar, the manner in which the inner liner is unfolded and opening when the pouring spout is lifted.

Figure 2 is a View in perspective showing the inner liner alone.

Figure 3 is a fragmentary view of the package shown in Figure 1, with portions thereof broken away to better illustrate the structure.

Figure 4 illustrates the shape and fold lines of the die-cut outer container as it appears before folding.

Figure 5 is a view in perspective of a package embodying'my invention in a modified form, and

Figure 6 illustrates the shape of the die=cut blank forming the outer container of the package shown in Figure 5.

Referring now to these drawings, and to Figures 1 and 3 thereof in particular, in which the outer container has been indicated by the numeral H1 and the inner liner by the numeral H.

The outer container is preferably die cut, in the shape illustrated in Figure 4, from light weight fiberboard or like material. This outer member of'the package includes side portions l2 and I3, and end portions It and I5 which, when folded along thelines l6, l1, I8 and 19, form the walls of the carton. The tab 20 is: secured to the end wall 15 by adhesive applied as at 2! in the usual manner. Extensions 22 and 23 of the side walls and 24 and 25 of the end walls, when folded along the line 26, provide an overlapping closure 22a for the bottom, and these portions are sealed by means of adhesive applied, as at 21, along the outer edges thereof.

The top closure departs from the usual box cover in the following manner. An extension'28 of the end wall !5 and extensions 29' and 30' of the sidewalls, when folded along the line 3!, overlap to provide a short cover portion indicated generally at 32c. This partial top is glued down along the edges of the portions 29 and 30, as shown at 32 and is preferably of sufiicient size to close approximately one half the top. openmg.

The remaining open. portion. of; the top- 01 the 31 carton is closed by a cover 33 hingedly attached near the top edge of the end wall l4. This cover 33, along with the arcuately shaped lateral projections 34 and 35, forms a pouring spout. The cover portion 33 comprises an extension of the end wall I4, although a small reinforcement or spacer portion 33 is preferably provided therebetween. This spacer portion has lateral projections 31 and 38 bent over and secured by adhesive to the inner sides of the side walls l2 and I3.

The arcuately shaped side walls 34 and 35 of the spout slide inside the side walls of the carton but on the outside of the inner liner H, as will be hereinafter described. The outer ends of the spout side walls 34 and 35 have projections 39 and 40 which are adapted to engage the underside of the top wall 29 so as to limit outward movement of the spout. The cover portion 33 of the spout includes an extension 4| adapted to overlap the edge of the solid top 32 and be sealed thereto, by means of adhesive, during packaging.

The edge 42 of the top wall flap 23 preferably extends beyonds the edge of flap 33 and is notched or formed with teeth, as shown, for the purpose of facilitating the tearing of the inner liner, as will be hereinafter explained in greater detail.

The inner liner H is constructed of a sheet of moisture resistant material such as waxed paper, folded as shown in Figure 2. The vertical edges are joined together, as at 53, and the top portions 45 and 45 of the side walls 45 and 4'! respectively are folded over in overlapping relation as at 38. The top portions 43 and 53 of the end walls are then folded inwardly to overlap the portions 44 and 45 of the side walls. The overlapping joints are preferably sealed by means of hot folding irons in accordance with common practice.

The bottom i may also be closed and sealed in the manner just described but, for reasons which will hereinafter become more apparent, I consider it preferable that the inner liner be filled apart from the outer container and through the end 5| which may then be folded or sealed in any suitable manner. The filled liner may then be slid into the outer fiberboard container i0 through the end 22a or the container l0 may actually be wrapped and formed around the liner l l, depending upon the type of equipment available.

In whatever manner the container may be formed, it is a feature of my invention-that one of the overlapping end flaps or top portions of 49 of the liner, being secured to the pouring spout by adhesive, as above described, is raised, unfolded and unsealed when the spout or cover is opened. Continued lifting of the spout results in opening the inner liner somewhat as shown in Figure 2, which permits the contents of the package to be poured out through the opening, the cover member of the package serving as a spout to prevent scattering of the contents.

Closing the package is accomplished by simply lowering the spout. The folds of the inner liner tend to fall back into their original positions and although the liner is not actually resealed, it, along with the hinged spout, serves to effectively exclude moisture from the interior of the package.

The pouring opening available in the inner liner, when constructed as just described, may

the end walls 49 or 50 of the liner be positioned in contact with the inner surface of the cover 33,

= the cover being closed and sealed at 4! A spot of adhesive or hot wax, indicated at 52,

-may be applied to either the inner surface of the cover 33 or the outer surface of the flap 49,

.to thus secure those two parts together.

The manner of use of the device hereinbefore described and some of its many advantages and features may become more apparent with the following explanation.

The package, filled for example, with dry cereal (for which it is particularly well adapted), may be opened by either breaking the glued joint 41 which secures the pouring spout, or by cutting the cover portion 33 of the spout along the line 53. The free end of the spout may then be lifted upwardly toward the position illustrated .in Figures 1 and 3. The overlapping end flap in some packages, be relatively small, and it is for this reason that the toothed edge 42 is provided on the box top flap 29. When the pouring spout has been raised, as far as the inner liner will permit, the portions 44 and 45 of the overlapping top of the liner are lifted upwardly so as to cause those parts to be torn against the tearing edge 42 and as'indicated at 54. When the liner is torn in this manner, the arcuate side walls of the spout hold it in shape.

It should be noted that the top overlapping portions of the liner may be folded in various ways. The creases or folds at 55 and 56 may, for example, fall in place at various angles to the top side edges of the carton. The exact shape .in

which the top of the liner is folded is determined somewhat by the packaging machinery employed.

In the modified form of my invention illustrated in Figures 5 and 6, the package, as a whole, is very similar to that shown in Figure 1, the major point of difference being that the side walls of the spout, instead of telescoping between the walls of the outer container and liner, are creased and pleated to permit the cover to be folded down to close the box top. The outer fiberboard container 88 is die-cut as shown in Figure 6 with side and end wall portions 61, 62, 63 and 64 respectively and overlapping lower end extensions 55, 65, B1 andES thereof forming the bottom closure 59 for the container. The fixed or permanent portion 10 of the top closure consists of the overlapping extension portions 1!,12 and 13 of the end wall 64 and the side walls 32 and 6 l.

The pouring spout 14 includes the cover portion 15 which is formed as a continuation of the end wall 63. The pouring spout side walls are formed as extensions of the side walls 6! and 62 respectively and it will be noted that these wings are creased, as indicated by'the dashed lines 18 and T9, to facilitate pleating of those members when the top is closed during packaging.

The inner liner is formed of material such as waxed paper as hereinbefore described." In this embodiment of my invention, however, it is believed preferable that the liner be placed in the outer box 53 before filling, after which the end flap ,1! may be turned down and then the top flaps I2, 13 and the cover 75 in the order given, those members having previously received an application of adhesive, as indicated at 8|.

It may now be understood that the top closure portions 82 of the liner will adhere to the inner sides of adjacent cover portions and the liner may be closed simultaneously with the outer cover.

When the pouring spout 14 of theouter'container is raised, in opening the package, the adjacent portion of the liner is also raised and opened to form a spout liner. Since the side wall portions 82 of the spout liner are cemented to the wings or side walls of the pouring spout, the top overlapping portions of the liner will tear readily along the toothed tearing edge 83 to permit the spout to open fully to the position illustrated in Figure 5.

A carton or package such as I have herein described is well suited to the packaging of many dry commodities, but especially well adapted for dry cereals.

The package provides not only a neat, efficient way of dispensing cereals and a quick and easy method of opening and closing the package, but provides means, operable by the closing of the carton top, for resealing the liner as well as the outer package.

Although I have described specific embodiments of my invention, it is apparent that modifications thereof may be made by those skilled in the art. Such modifications may be made without departing from the spirit and scope of my invention as set forth in the appended claims.
