POURING SPO'UT FOR CARTONS AND RECEPTACLES Application filed November 2, 1923. Serial No. 672,429.

To all whom it may concern:

Be itknown that I, ERAs'rUs S. ALLEN, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Pouring S outs for Cartons and Receptacles, of whic the fol.- lowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

The object of my invention is to provide a simple and effective pouring spout for cartons and the like, which can be sealed perfectly against the sifting out of any powdered material, with which the carton may be filled, and which spout can be readily and easily opened out fer pouring with any pointed instrument without cutting the carton on any line of marking.

Heretofore spouts have been provided for cartons and receptacles'formed of tin or even of paper material, but so far as I am aware separate parts have to be secured to the carton or extra work performed in the manufacture of the carton which very materially adds to the expense. One of the particular objects of my invention is to purposes only.

devise a construction which may be formed at the same time that the blank for the carton is prepared and without'any extra labor, and which will require no modification or change in the machines for manufacturing the carton, and in which without modification or change, the adhesive material which is applied for securing together the sides of the cartonblank shall also be applicable for sealing the spout, the onlyrequirement being a slight increase in the width of the sealing flap of the carton in those instances, where my invention is applied to any of the simplest constructions of cartons. c,

I accomplish these results by that certain novel construction to be hereinafter more particularly pointed out and claimed.

I have illustrated my invention in connectioniwith one of the sim lest constructions of cartons but it .will e understood that the spout can be efl'ectively applied to at great variety of forms of cartons and that the particular form is for illustrative In the drawings: v Fi re 1 is a plan view of the blank from whicfi the carton is constructed.-

Figure 2 is a perspective view of the carton complete filled with the material and ready for use. v 3

Figure 3 is a similar view with the spout opened out for pouring.

Figure 4 is an enlarged vertical section of the spout portion. 1

The blank for the carton which, as I have stated, is of simple construction, is cut and scored 'as shown in Figure 1 to form, for a rectangular carton, four sides 1, 2, 3 and 4 with a sealing flap 5, attached to one of the sides, the parts separated by score lines 6, 7, 8, and 9. End flaps for the top ,and bottom 10, 11, 12 and 13 and 14, 15, 16 and 17 are also provided with score lines i19'and 20, and separated from each other by cut lines as shown. Two of these flaps for each end are preferably of the cross sectional dimensions of the complete carton with the intermediate flaps preferably shorter, so--that when the carton iserected the intermediate flaps canbe turned in without overlapping and with the other flaps to overlap} and to be glued down to form a tight closure. 7

The sealing flap 5 which when-the carton is formed is to underlie the side flap 4, and I to be secured by adhesive material. is cut and scored to form the spout at\the same time that the carton blank itself is formed.

This spout portion is formed bv cut or severed lines 21, 22, 23, 24, 25 for-the upper end and upper edge of the. sides 40 of the pose to "be described. Instead of employ-V ing the edge of the flap 5 for one side edge of the. spout, in many cases it will be preferable to form the spout entirely inside the flap 5, cutting a separate line inside the outer side edge of the flap. Also instead of forming the ears 33 and 34, the cut lines 22 and 24 may be made more nearly horizontah It will be understood, of course, that the dimensions of the spout portion are a matter of choice, andlarger or smaller s uts may be provided, limited by thewi th of the flap 5, and if desired,-the entire spout por tion may be out inside the free edge of the flap 5. When the carton is formedtheflap 4 is to overlie and cover the sealing flap 5.

On this flap 4 at the same time and with the same machine 0 eration of dies that form 5 the other cut an scored lines, I cut the lines 23 to coincide with the portion 44 on the sealing flap 5.

After the blank is cut as above described, adhesive material is applied usually by a machine glue roller, or otherwise and this adhesive isapplied lengthwise of the flap 5,

the carton is folded so as to bring the flaps 4 and 5 together; this act glues the narrpw strip 39 to portion 44, an d glues together the spout front portions 41 and 42. The carton 25 is then erected, the bottom-flaps folded in andsecured by adhesive, the carton filled and the top flaps folded down and secured and the package is ready for shipment. As the cutlines of the spout portion of the two flaps 4 and 5 do not coincide, and

the outer flap 42 is secured by the adhesive -to the strips 39 and 42, there is no chance of leakage orsifting' of the material in the carton no matter how fine and powdery it may be.

To open the spout all that it is necessary to do, 1s to insert a sharp pointed instrument at the middle of theline 37 preferably in a downward direction so that the point will pass through the cut 1ine23, and then;

pull out'the front spout flap 42. This action-folds the sides of the spout, and the cars 33 and 34 will prevent the spout being drawn out too far. When it is not desired to leave the spout open, it can pushed back after use, to be drawn out each time the contents of the carton are to be ,dis-

charged.

It will be obvious that my construction of spout can be applied to any construction of carton in which there is a substantial overlap of the carton flaps, so that the body of the spout can be cut and scored on the underlying flap, with a cover piece cut and scored in the outside flap to'bring the cut lines of .onepart in register with the score lines of the other." In this way until the seal is broken, there is no opening for leakage and the seal can be readily broken to openout the spout.

I therefore, do not wish to limited to any partlcular construction of carton, or to the size and location of the spout construction, except as indicated in the above description.

Having thus described my inventiomwhat I claim as new and desire to secure by Let:

ters Patent, is

..1. A container having overlapping portions, the underlying portion 'aving cut lines forming a pattern of the side and top walls of a dispensing spout, the base of said dispensing spout articulated to the underlying port on, said out lines out of register with cut lines forming a pattern of a withdrawal flap in the overlying portion and means for sealing said cover flap to said pattern of a dispensing spout whereby adhesive applied to seal said underlying and overlying portion of the container shall seal said pattern of a withdrawal flap to said pattern of a dispensing spout.

2. The combination with a carton having a securing flap to secure the sides together, of a spout blank formed ortion ,of the carton, the spout blank in the underlying ormed by cut lines for the top of the front wall and the outer edges of articulated side wings of bottom of the front wall and inner articulated edges of the side'wings, with the overlying portion of the carton opening in which the sides are out of alignment with the cut portions of the spout and through which the spout blank is drawn to form the spout, with an articulated flap closing said opening on the overlying portion of-the'cart'on to open and close the opening, with sealing means dis osed on the central longitudinal portion 0? said securing fla" between the articulated portions of the si e wings of the spout to seal the securing flap and the inner and outer front wall of the spout.
