l CARTON Filed Nov. 16,y 1929 Patented Dec.. '22, 1931 U N l T E NT ICE RALPH K. BECKER, OF CLEVELAND, OHIO, ASSIGNOR OF FORTY-FIVE ONE-HUNDREDTHS T0 BERT IVI. KEN-T, OF CLEVELAND, OHIO CARTON Application led November 16, 1929. Serial No. 407,589.

This invention relates to cartons having pouring spouts formed therein and, more particularly, relates to certain improvements in the carton disclosed in my earlier application Ser. No. 387,612, filed August 22, 1929.

It is one of the objects of the invention to provide a cart-on of the usual rectangular shape, that is commonly used for packing granular or powdered materials, in which the pouring spout is formed within the limits of the ordinary blank that is now used to make a carton without a pouring spout, so that thc provision of the pouring spout would not require the use of any additional material.

A further object of the invention is to provide a carton with a pouring spout which may be formed therein in connection with the operation of cutting out the blank for the carton so that no additional blanking operations are required.

A further object of the invention is to pro vide a carton with a pouring spout device that is so formed that the carton may be 1nanufactured on the equipment that is now used for the manufacture of cartons, without pouring spouts, and which may be sealed by the usual sealing machines and not require any special equipment.

It is a further object of the invention to provide a carton having a pouring spout that will be devoid of externally projecting parts, that may be conveniently and quickly opened, and that may be readily closed and positively retained in the closed position.

Other objects of the invention and the features of novelty will be apparent from the following description taken in connection with the accompanying drawings, of which- Fig. l is a perspective view of a portion of the carton, embodying my invention, the pouring spout being shown in the open position;

Fig. 2 is a perspective view of the carton, as it appears before the pouring spoutdevice is opened;

Fig. 3 is -a plan view of the blank for this carton;

Fig. 4 is a perspective view of the end of 5o the carton, which contains the pouring spout device, with the flaps about to be folded into I the sealed arrangement;

Fig. 5 is a view similar to Fig. 4 but showing all but the outer iap, in the sealedarrangement; and

Fig. 6 is a View similar to Fig. 2 with a portion of the outer flap broken away to show the arrangement by which the pouring spout is locked in the closed position.

Referring to Fig. 3 of the drawings, the blank from which the carton is made is formed from paper stock, in the usual manner, by means of dies which score the blank along the

lines

10, 11, 12, 13, 14 and 15, these score lines defining the

sides

16, 17, 18 and 19, of the carton. A sealing strip 20 is left along one edge of the side 16 and has the extensions 21 and 22 at its opposite ends. When the cart0n is assembled the strip 20 is glued to the inner surface of the side 19, along the edge 23, and the extensions 21 and 22 are glued to the inner surfaces of the

flaps

24 and 25, respectively. One end of the carton is formed by the'flaps 24, 26, 27 and 28, these flaps being folded into overlapping arrangement and glued together in the usual manner. The opposite end of the carton is formed by the

flaps

25,29, 30 and 31, but these flaps are especially formed to provide the pouring spout device which Will now be described.

The flap 3Q is formed with a tongue 32 which is crea-sed along the

lines

33 and 34 and cut along the lines 35, these cuts ending at the points 36. The

crease lines

33 and 34 permit the tongue 32 to be folded into U-shape, as shown in Fig. 1.

The flap 29 is formed with a U-shaped opening 7 which forms a tongue 38 and when the carton is assembled the opening 37 is arranged over the tongue 32 and the tongue 38 is glued to the tongue 32 so as to act as a reinforcement for the latter. The iap 29 is also provided with an opening 39 which is separated from the opening 37 by the bridge-like portion 40, which will be hereinafter referred to.

The iiap 25 is provided with the cutlnes 41 and the flap 31 is provided with lines of

perforations

42, 43, 44 and 45, arranged as shown. Within the portion bounded by the

lines

42, 43, 44 and 45, there is a U-shaped cut or perforated line 46 which forms a tongue 47 that is adapted to be secured on the tongue 38. The flap 31 is also provided with a cut line 48, arranged at right-angles to and meeting the line 45.

The manner of folding the

fiaps

25, 29, 30 and 31, in order to seal one end of the carton and form the pouring spout therein, will be apparent from Figs. 4 and 5. The iap 25 is first folded to the position shown' and then the flap 30 is folded in so that the end-of the tongue 32 will overlie the end portion of the flap 25. The flap 29 is provided with glue on its inner and outer surfaces and is thenV folded down on the

flaps

25 and 30 so that the tongue 38 Will be secured on the tongue 32as shown in Fig. 5. The flap 31 is then folded` over the flap 29 and glued thereto, the ton ue 47 being thus secured on the AVtongue 38. y these operations the end` of the carton will then be entirely sealed, as shown in Fig. 2.

The various cut lines and openings Ain the different flaps are so arranged that, when the flaps are in their sealed arrangement, the

lines

45 and 48 will be over theopening 39 and the bridge-like portion 40 will be secured to the inner surface of the section 49,` of the iap 31.

The opening 39 and the cut 48 permits the portions of the Hap 31, lying on opposite sides of the line 48, to be depressed so as to enable one toy insert the linger nail or a tool under the edge of the section 49, that is formed by the line 45. The section 49 may then be torn out, thereby leaving the tongue 47 attached to the tongue 38. The end 50 of thepouring spout will then be accessible and the spout may be withdrawn through the opening formed by the removal of the section 49 and, as the spout iswithdrawn, ythe longitudinal edges of this opening will automatically fold 4 the spout as shown in Fig. 1 and, in this condition, it may be used for pouring out the contents of the carton. When it is desired to close the spout, it is pushed back to its initial position and, as it returns, the edges of the tongue 32, which form thevsides 51 Yof the spout, will engage in the cuts 41, as shown in Fig. 6, and thus hold the spout in its closed position. The cuts 4l also increase the flexibility of the portion of the {iap 25 which underlies the tongue 32 and thus facilitate the withdrawal of the spout. Since the removable section 49 will, in sealing the end of the carton, be glued to the bridge 40 this'removable section will be firmly supported and, at the same time, thoroughly secured in its position. In removing the section 49, it may take the bridge 40 with it or the gluing may break but, in either case, the removalof the section 40 is very simple.

Having thus described my invention, what I claim is z \-1. A carton having a Wall comprising three outer flap through which said spout-forming section is accessible.
