Claims. (Cl. 229 -17 This invention relates to a pouring spout carton, that is, to a'paper board carton which is equippedwith a pouring spout. The main objects of the invention are to provide a carton in which a pouring spout is formed as an integral part of the carton; to provide a pouring spout structure which may be embodied in the carton as a part of the normal wall structure thereof and without the addition of special spout forming pieces of material; to provide a very simple, low cost pouring spout construction which is very easy to open and close and which is self-closing; and, in general,'it is the object of the invention to provide an improvedpouring spout carton. i
Other objects and advantages of the invention will be understood by reference to the following specification and the accompanying drawing (1 Sheet) in which there is described andillustrated a pouring bodying a selected form of the invention.
In the drawing:
Figure 1 is a perspective illustration of a carton embodying a pouring spout according to the invention;
Figure 2 is a perspective illustration of the carton with the pouring spout opened; and,
Figure 3 is an elevational view of a portion of the blank from which the carton is formed and which contains the improved pouring spout structure.
The improved pouring spout according to the present invention is applicable to a corner portion of a paper board carton. In this instance it isillustrated as applied to a conventional carton 1 of rectangular form and having its top and bottom ends 2 and 3 closed by overlapped end flaps in the usual manner. structure 4 is provided in the corner area of the carton formed by the intersection of a pair of walls 5 and 6.
Said pouring spout structure 4 is formed by a pair of weakened score lines 7 and 8 in the walls 5 and 6 respectively. Said weakened lines 7 and 8 may be ordinary perforated scores as shown, or they may be cut scores in which the cutting goes only part way through the thickness of the carton walls, or any other weakened lines which may easily be broken or cut to provide slits through the walls in registry with said lines 7 and 8. These potential slits 7 and 8 intersect at 9 in the corner 10 of the carton and they extend downwardly and away from said corner at acute angles thereto. A pair of fold lines 11 and 12 in opposed relation to said potential slits, intersect at 13 in said corner 10 and said fold lines 11 and 12 extend into the respective walls 5 and 6 at acute angles relative to the corner 10 and toward the potential slits 7 and 8.
A pair of fold lines 14 and 15 interconnect the free ends. of the potential slits 7 ,and 8 respectively to the free ends of the fold lines 11 and 12 as shown, said fold lines 14 and 15 being disposed in spaced, substantially parallel relation to said corner 10.
A pair of fold lines 16 and 17 is provided in the wall 5, this pair of fold lines intersecting as indicated spout carton em- A pouring spout 2,842,302 Patented July 8, 1.958
lCt
other in the corner 10 at the point 18 where'sai fold lines 16 and 17 intersect. Said pair of fold lines 19 and 20 extend angularly from the intersection-18 'to' the junctures of the fold line 15 with the potential slit 8 and fold line 12.
When the spout structure 4 is to be opened, the Weakened lines 7 and 8 are out through with a knife .or broken open by the application of pressure to'the pouring spout structure adjacent said lines ,7 and, 8. The spout is then capable of being opened bythe application of pressure to the corner of the box immediately below. the fold line intersectionpoint 18 as "illustrated in Figure 2, such pressure being". directed towardthe inside of the box. Such inward offsetting of the box corner portion defined by the fold'lines 11,.12, 14,15, 16 and 19 causes outward offsetting to pouring spout position as shown in Fig.2, of the box corner .po'rtion defined by the slit lines 7 and 8 and the-fold lines 16 and 19. I i
The, opening action of. the spout appears to depend upon hinging of the outwardly offset spout portion about the fold lines 16 and 19, the upper end portions of which are substantially fixed in the planes of the walls Sand 6 and the lower portions of which are moved. inwardly when the lower portion of the spout structure is pressed inwardly. Flexibility of the box walls also enters'into the opening action in that it permits the spout portions intermediate the lines 14 and15 and below the fold lines 16 and 19 to be passed from their normal angular wall relationship as shown in Figure ,1 through a coplanar position and to a carton entering}angular..relationship in which the spout is fully'opened. i
It is not necessary that the slit lines 7 and 8 be angularly disposed in the manner illustrated, the important thing being that they connect the ends of the fold lines 14 and 15.
Other changes in the described structure may also be made while retaining the principles of the invention.
