themovement ofsaid closure, the said carton n being formed from one blank of material.

Attempts have been made prior to this invention to form a closure type of pouring spout in cartons, however, the same proved objectionable for various reasons, one reason being that in most l0 instances such Closures while they provide an opening for pouring out the contents, they did not provide satisfactory closure means.

In prior art attempts, no guides have been provided for the side wings of the lpouring spout or l closure, and for this reason the said side wings would be forced together by the material or contents within the carton, especially, if the same were of:a granular nature, which would tend to wedge in between the said side wings and the wall of the carton, thus defeating the purpose for which the closure was originally provided.

' My invention is so constructed that the carton is provided with guide ways for guiding the side flaps or wings of the closure in their movements,

and for frictionally engaging the same in cooperation with the wall of the carton for maintainin 'the closure in a closed position. I

Other feature, objects, and advantages resident in my invention will become apparent from an examination of the accompanying drawing in connection with the ensuing description wherein like numerals or symbols are used to designate like parts and in which;

Fig. 1 represents an isometric orperspective 35 View of my invention showing the top and bottom thereof partially completed so as to more clearly elucidate the nature and construction of my invention.

Fig. 2 is a view showing the methodof cutting 40 'the blank needed to construct or manufacture a carton in accordance with the teachings of my invention.

.3 is a. top view of the view vshown in Figure 5.

Fig. 4 is an enlarged fragmentary view in perspective of the closure means comprising the essential part of my invention.

Fig. 5 is a. fragmentary front view of the top portion of the carton comprising my invention.

Referring to the drawing, Figure 1 illustrates a carton generally designated 6 comprising my invention which is almost completely folded t0 illustrate the nature of the construction. Re-

ferring to Figure 2, I will attempt to elucidate the 55 manner of cutting the blank generally designated 1 in order to permit folding to such shape as indicated in Figure 1.V The blank is made up of a series of walls 8, 8', 9 and 9'. The wall 9 extending somewhat further and providing a sealing tab l0 which permim securing the same to the wall 8 in order that the body of the carton be formed when folded over the weakened portions 28, 29, 3ll,.andv3l. The sides of the walls, 8, 8', 9 and 9' respectively, are scored as at 21, 26, and 25 in order to weaken the carton material and to permit folding the same on the said weak-2 ened lines. i

Adjoining the edges 21, the flap portions Il, I3, l2 and ll are integrally secured to the 'respective walls 8, 9, 8' and 8', the saidiiaps being separated by the incisions 2l, 2| and 22 thus folding over as indicated in Figure 1 to form the bottom of thecarton. In the standard carton, the top portion is similarly formed so that the carton is similarly closed on the top and whenopened will not provide a pouring spout nor a. closure for closing the same and thus will not prevent dust, dirt and other objectionable matter within the atmosphere from admixing with the contents.

, In order to permit a construction of a carton such as my invention provides, the blankfor the top portion is cut as indicated at the right `hand side of Figure 2, and it indicates a. flap Ill which is but a portion ofan imaginary flap similar to the one designated Il on the opposite side. The closure spout is formed from material taken from adjacent flaps in order to form the resultant ilps I8 and thus provide the central nap I5, which is hinged at 25, with side wings I6 having heel portions I1 by virtue of the incisions 33 cut co-linearly with the weakened portions 25 and 26 The ap l5 is also scored at 24 inorder to.

weaken the same and permit thewings tito be folded at right angles thereto. The recesses formed by the heel portions I1 are connected to'theedge of the iiap I8 by bias lines I9 ccnvergent toward-'one another. Itis also to be noted that the central iiap I5 is provided'with anextensionz whichmaybecov'eredwithglue f or other sealing material so that when the carton is lled and closed for distribution, the seal .will be of a more or less permanent nature, yet

when the carton is to be distributed to consumers,

the consumers by the seal portion under the nap 32 will have a pouring spout and closure which will open up almost to an erectpositionbecause the wings I5 span substantially 90, and thus provide a good sized opening.

The edges I9 of the naps ls wm be folded over in a manner so asvto provide a frictional guide way betweenthe edges I9 and the inner portion .of the walls 8 and 8' of the carton, thus from the very beginning of movement of the closure,

v the wings I6 will'be caused to move in a direction ency to wedge between the Wings' I6 and the inner portion of the walls 8 and 8 causing the naps or wings I6 to converge toward one another and defeat the purpose of providingpa sanitary seal.

It is contemplated that the guide ways being also sufciently narrow and restricted with respect to the'closure flaps I6, so that'sucient frictional resistance will be aorded for maintaining the closure spout 34 in its closed position, at. the same time the wings will be maintained from becoming distorted by contents Within the carton wedging between the Wallsl and the wings'when the said closure is operated.

My invention, primarily, provides a closure which has the auxiliary attributes of furnishing a pouring spout at the same time.

Altho, I have indicated a preferred form of my invention and inasmuch as it is susceptible of many; alterations, modifications and improvements, I reserve the right to all such alterations, modications and improvements which come within the scope and spirit of my disclosure and within the purview of the foregoing description;

f my invention to be limited only by the subj oined claims.

Having thus described. and revealed my inven- 1. A carton blank comprising, a number of wall portions, flap portions hingedly secured to opposed edges of each of said wall portions, and a pouring spout and closure blank portion comprising, an intermediate apportion having hingedly secured Athereto Wing portions shaped to the configuration of a quadrant of a circle, the said wing portions formed from`material taken from ap portions adjacent said intermediate ap portions, the edges of said adjacent flap portions adjacentr the said wing portions converging toward each other and having their free ends spaced from one another a distance less than the spaced -dis- G tance of the free ends of the said wing portions, the length of each of said adjacent flap portions being'less than the width of the said intermediate ap portion only substantially to the extent of the thickness of one of said wing portions.

2. A carton formed from a single blank comprising, a pouring spout and closure integrally hinged with one wall of the carton and adapted for closing a portion of the top of the carton, said spout having side wings slidable against the interior surfacesv of opposite walls of the carton, and naps integrallyhinged with the ,upper ends of said opposite Walls and folded in overlapping relationship for closing the remainder of the top of the carton, each ap having its edge adjacent said spout'cut on a bias from a point in` its hinge portion adjacent one edge of an adjacent wing to the opposite edge thereof in the directionv of the spout so as to clear the edge'of the Wing of the spout adjacent .thehinge and voverlap theinner face of the other Wing forthe purpose set forth. t v v j.
