therefrom and more especially to a standard carton blank and carton so constructed merely by scorings and perforation; that the carton can be conveniently opened for pouring and can thereafter be conveniently reclo'sedlnd held in closed positionkeeping the contents from expo- 4sure to dust and the atmosphere, I am aware that numerous cartons for effecting this object to cartons provided with l vmeans for pouring` or dispensing the contents solenne (ci. :as-17) Fig. 2 is a fragmentary view from the blank of Fig. 1,

, corner` nap broken open and pressed to closed have been heretofore suggested but to my knowlv edge suchc'artons have embodied the employment of lelements to the'carton, the cartons j have besnoipecial or unusual conilguration'requiring.' new and expensive forming machinery,- and other features rendering'the cartons more expensive and complicating their manufacture andaise have been required.v One primary object rt-,my invention resides in the production oi' an extremely simple, new and improved carton of this nature solely embodying a standard carton blank so scored and perforated as to provide a,

pouring exit when the carton is broken open and adapted thereafter to be closed and held in closed position when not in use.

Standard cartons have heretofore been perforated along a curved line through one wall t provide a flap which when bent ror broken outwardly leaves a hole through which the contents can be dispensed. This flap is however not adapted to reclosing of the carton and, after opening the carton, its contents are thereafter continuously exposed to the atmosphere. I have discovered that by perforating a carton lblank along a line extending obliquely across two adjacent walls thereof adjacent to one corner of the ,carton to be formed and across the junction of said walls, together with two perforations respectively in 'said walls and extending from said line in a direction away from said corner, a pivoted corner closure nap is formen which when not in use can be pressed to closed position and into frictional .Engagement within slots provided by said two perforations and will'remain in such position keeping the carton reclosed against exterior exposure. The production of such an improved blank andcarton comprises a further object of the invention.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawing in which,

Fig. 1 is a fragmentary end view of the carton blank,

position, and

Fig. 4 is a fragmentary view of the carton with the corner ilap in open position.

My invention is applied to a standard carton blank Il having front and rear body walls I2,

edge walls i4, end iiaps ilf connected to the walls, and a sealing flap i8 along the free edge of one body wall. The blank is scored along the junction line 20 between the body and edge walls and the end napsand, in accordance with my invention,

' obliquely across the faces to points-30 short of 'the Junction 24 and from thence directly across the blank is perforated along a line 22 extending from two points on the line obllquely across two body and edge wallsand across the scored Junction 2 4 of these walls. -In the preferred construction and, as illustrated, this perforated line 22 extends from two points 28 toward each other along the scoring 20 to points 28 and from thence such junction. The two adjacent faces are perforated along lines 32 from points 30 in a direction away from the scoring 20, The adjacent end liiaps connected to the perforated walls i2 are also preferably scored'obliquely, thereacross from the points 2l along lines 34 and 3l as illustrated'in Fig. 1*, and the other bodywall flap is also preferably likewise scored across one corner at 38.

When the blank as above prepared is folded into a carton lil, the three scored lines 34, 38 and 38 will coincide along the line 42 extending across a corner of the carton end. When it is desired to use the contents of the carton, the walls are broken along the perforated lines 22 and 3 2, thereby freeing the corner 44 for outward pivotal movement about the line H42. In such open position, as lustrated in Fig'. 4 the contents .of the' .carton be poured from the corner spout Il thus formed.

When the carton is not in use the closure Il can be placed in the closed position illustrated in Fig. 3 in which position the two side walls oi the closure corner engage frictionally within the slots at 32 whereby holding the comer in such closed position. It will be apparent that the frictional engagement will serve its holding function regardless of the use of the carton and numerous opening and closing of the corner closure.

It will now be apparent that my invention provides a cntqn which can be readily opened to a position providing a pouring spout, as illustrated in Fig. 4, andwhich embodies a closure M which ofa carton formed Fig. 3 is a like view showing the perforated' to the atmosphere when the carton is not in use. It will furthermore be noted that these novel fea- Vtures are provided on a standard carton blank merelyby perforating and preferably scoring the carton as described and illustrated. Also, while I have illustrated the faces I2 and I4 asperforated at 32 along lines extending away from the comer closure M it will be apparent that theperforations can extend in the opposite direction whereby placing the slots 32 in the Walls of the corner closure, Y

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

v thus .protect the contents from dust and exposure v Y' .the t'wo end portions of said perforated line ex- 1. A carton perforated adjacent to a corner y thereof along a line extending across the junction of two faces radiating from said corner and obliquely across said two faces to two margins thereof radiating from said corner, the intersection of said line with said junction being substantially closer to'said corner than to any other corner of the carton, and said two faces also being Vperforated respectively along two lines spaced from said junction and each intersecting the first named line and extending away therefrom, said perforations across `the junction and across said two faces forming a corner closure having one edge portion adjacent to and receivable in the y slots formed by the perforations -along said two lines spaced from said junction.

2. The carton defined inclaim 1 'in which said perforated line extends along one of said twomargins to an adjacent/corner of the carton and a substantially equal distance along the other` of said vtwo margins, and iny whichl the carton is scored from said adjacent corner to the end of said line on said other of the two margins.. l 3; The carton defined in claim 1 in whichV said perforated line extends obliquely across said two faces from said two margins ina direction toward but short of a predetermined point on said junction rand from thence directly across said junction, and in which said two lines intersect the Y first named'llne Yat the two pointsy where the'line extending directly across the junction joins the "obliquely extending lines..

. 4. A' carton blank comprising front and rear body walls, edge walls connected thereto and end aps ron said walls at one end of the blank, the blank being scored along the junction of the flaps with the walls, one body wall and an adjacent edge wall being perforated obliquely thereacross 4a. I along a line extending from two points on said junction scorings to and across the junction of said body wall and edge wall, and said one bodyv wall and edge wall being respectively perforated along two 'lines each intersecting the irst named line and extending therefrom in a direction away i from said scorings, said two lines being spaced from and located 'at opposite sides ofthe last named ,junction and providing slots for receiving the adjacent edge portion of the blank.

5. The carton blank defined in claim 4 in which tend respectively along and coincide with the rst named junction to points substantially equal disi tances from the second named junction.

the two end aps on said one body wall and adjacent edge wall are scored obliquely thereacross from points on the first named ljunction located at the two outer ends of said perforated line to substantially a common point located at the ad-V jacent edges of said two end aps.

7. The carton blank dened in claim 4 in which the two end flaps on said one body wall and adjacent edge wall are scored obliquely thereacross from points on the ilrst named junction coincident with the two outer end portions of said perforated line to substantially a common point located at the adjacent outer corners of said two end flaps, and in which the end iiap on the other iiaps'turned down to close the end of the carton;

8. A carton blankcomprising front and rear body walls, edge walls connected thereto and end flaps on said walls at one end of the blank, the'r blank being scored Aalong the junction of-the flaps with the walls, one body wall and an vadjacent edge wall being perforated obliquely thereacross along a line extending from two points on said-junction .scorings in a direction toward but short of a predeterminedrpoint on the junction of said body wall and edge wall and from thence directly across the second named junction, and f said one body wall and edge wall being respectively perforated along two lines spaced from the second named junction and each intersecting the rst named line and extending away therefrom and providing slots for receiving theadjacent edge portion oi' the blank.
