Abstract
ABSTRACT OF THE DISCLOSURE
A container for holding a mass of a flowable solid material comprising a bottom, at least one end wall and a pair of side walls, each having a generally upright side margin therebetween to which the end wall is coupled. The end wall is provided with a pair of arcuate fold lines extending upwardly from respective side margins and being convergent relative to each other at a location near the upper extremity of the end wall intermediate the side margins. The side walls and end wall are formed of a material having sufficient flexibility to permit the sides to be moved toward each other while simultaneously allowing the end wall to flex outwardly along the fold lines so that the upper portion of the end wall forms a spout to control the pouring of the flowable solid material from the box.

1 1051;~~5 I ¦ SUM~RY OF Tll~ INVENTION
2 ¦ The present invention relates to containers, or
3 ¦ receptacles, for comminuted or granular free flowing substances ¦ such as cereals and the like. More particularly, the invention 5 ¦ relates to containers of a class having a portion of the fiber-6 ¦ board panels thereof distortable to simultaneously provide both 7 ¦ a discharge aperture and a V shaped pouring spout that can be 8 ¦ positively maintained in either a closed position or an open 9¦ position.
10¦ Alternatively, the invention is directed to a carton 11¦ blank including portions adapted to be interengaged in such a ~2 ¦ manner as to create a carton that will permit manipulation 13 ¦ of a pouring spout into an open and a closed position merely by lql distorting the fiberboard itself.
15 ¦ . This invention resides in the discovery that by 16 ¦ utilizing certain arcuate fold lines in a side wall of the 17 ¦ container, the container can be readily distorted and locked 18 ¦ into a V-shaped pour spout configuration merely by momentarily 19¦ applying sufficient pressure to deform the sides of the carton.
20 ¦ Thereafter, the application of a corresponding amount of 21 ¦ pressure to the tip of the V-pour spout will cause the fibsr-22 ¦ board to return to the normal rectangular carton configuration.
23 ¦ Thus, the present invention provides an integrated 24 ¦ paper pour spout distinguishable from those currently available 25 ¦ by its ease of opening and pouring, its maintenance of the 26 ¦ pouring configuration, its ability to be positively reclosed, 27 ¦ and the ability to be repeatedly opened and closed. It is a 28 ¦ principal object of this invention to provide a carton structure 29 ¦ that can be readily deformed into a fixed spout position to 30 ¦ improve material pouring, yet thereafter be returned to a 321 clo ed configur-ltion to p~ v~nt spilllng.

a pair of top end flaps hingedly attached to the back and front walls, and overlapping the first top end flap, each of the pair of top end flaps being joined to respective of the back and front walls in part by a tear hinge extending therebetween for a distance corresponding to the depth of the first top end flap, the back and front wall top end flaps being further provided with a fold line transverse to the tear hinge; a first pair of arcuate fold lines provided in respective of the back and front walls, each of the pair of arcuate fold lines having one end thereof intersecting with the upright side margin between the end wall and respective of the back and front walls, and the other end thereof intersecting the transverse fold line at the respective top end flap, the end wall having a second pair of fold lines extending upwardly from respective side margins and being con-vergent relative to each other intermediate the side margins at a location near the break-away tab, each back, front and end wall being formed of a material having sufficient flexibility to permit the back and front walls to be moved toward each other while simultaneously allowing the end wall to flex outwardly along the fold lines, whereby when the carton is filled with flowable materials, the particles can be dispnesed from the carton by first - 2a -~(~5~3~5 separating the tab along the tear line in the end wall and the tear hinges in the pair of top end flaps, then by bending the tab upwardly about the transverse fold line, and thereafter depressing the portions of the back and front walls defined by the pair of arcuate fold lines and the end wall, so as to temporarily lock into a pour spout configuration to control the pouring of the flowable material from the container.

A carton blank having a plurality of serially connected walls and a corresponding plurality of flaps hingedly attached at each end of said walls, a break-away tab formed in part by a tear line in a first end wall, said tab further being formed by the hinged attachment of said first end wall to a first top end flap; a pair of top flaps hingedly attached to front and back walls adjacent said first end wall, and adapted to overlie said first flap upon assembly, each of said pair of flaps being joined to respective of said adjacent walls in part by a tear hinge extending therebetween for a distance corresponding to the depth of the said first flap, said pair of flaps being further provided with a fold line transverse to said tear hinge; a further fold line having one end intersecting said tab, and the other end intersecting a first pair of arcuate fold lines; said pair of arcuate fold lines extending downwardly and outwardly in said first wall to opposite edges thereof, a second pair of arcuate fold lines provided in respective of said adjacent walls, each of said second pair of arcuate fold lines having one end thereof intersecting with the outer, downwardly formed end of respective of said first pair of arcuate fold lines at the junction between said first and said adjacent wall, and the other end thereof intersecting the transverse fold line at the respective flap, whereby when said blank is assembled to form a carton, and filled with free-flowing particles, the particles can be dispensed from said carton by first separating said tab along the tear line in said first wall, and along said tear hinges in said pair of flaps and then by bending the resulting separated tab upwardly about said transverse fold line, and depressing the portion of said adjacent walls defined by said second pair of arcuate fold lines, so as to temporarily lock in the form of a pour spout.
7. The carton blank of claim 6 further characterized by an arcuate fold line in said first wall extending between the outer, downwardly formed ends of respective of said first pair of arcuate fold lines.
8. The carton blank of claim 6 wherein each arcuate fold line is formed on an identical radius of curvature.
9. A container for holding a mass of flowable material comprising back and front walls, at least one end wall and top end flaps hingedly attached at one end of said walls, each said back and front wall being contiguous with said end wall through respective of generally upright side margins, a first pair of arcuate fold lines provided in respective of said back and front walls, each of said pair of arcuate fold lines having one end thereof intersecting with the upright side maring between said end wall and respective of said back and front walls, and the other end thereof intersecting the respective top end flap, said end wall having a second pair of fold lines extending upwardly from respective side margins and being con-vergent relative to each other intermediate said side margins, each said back front and end wall being formed of a material having sufficient flexibility to permit the back and front walls to be moved toward each other while simultaneously allowing the end wall to flex outwardly along said fold lines, whereby when said carton is filled with flowable material, the particles can be dispensed from said carton by depressing the portions of said back and front walls defined by said pair of arcuate fold lines and said end wall, so as to temporarily lock into a pour spout configuration to control the pouring of said flowable material from said container.
