Abstract
A multi-sided container, preferably formed of a unitary blank of paperboard, having a frangible perforated line in the center of a front panel defining a dispensing flap and two sets of fold lines radiating away from opposed sides of the perforated line. Once the perforated line is fully severed, pressure on the side panels adjacent the front panel causes the dispensing flap to move away from the front panel to define an enlarged dispensing orifice out of which the contents of the container may be poured. The perforated line has a linear portion and two curvilinear portions in the form of arcs of a circle, some of the radiating fold lines being tangent thereto.
Claims29
A container having a dispensing orifice comprising:
- a front panel, right and left side panels and a rear panel hingedly connected along parallel fold lines to form an enclosed chamber;
- a glue flap interconnecting said rear panel and one of said side panels;
- a bottom closure connected to the bottom of said panels to close the chamber at the bottom;
- a top closure connected to the top of said panels to close the chamber at the top;
- and
- means defining a dispensing flap in said front panel, said means including a frangible perforated line defining a dispensing orifice, said means further including two sets of a plurality of fold lines formed in said front panel, each set contacting said perforated line at opposed ends and extending from such contact to opposite sides of said front panel with one of said fold lines in each said set extending onto the adjacent side panel,
- whereby, once said dispensing flap is manipulated to fully sever the perforated line and form the dispensing orifice, pressure applied to said side panels causes said dispensing flap to extend outwardly from said front panel and away from said chamber to expand said dispensing orifice for the pouring out of the contents of said enclosed chamber.
A container having a dispensing orifice comprising:
- a front panel, right and left side panels and a rear panel hingedly connected along parallel fold lines to form an enclosed chamber;
- a glue flap interconnecting said rear panel and one of said side panels;
- a bottom closure connected to the bottom of said panels to close the chamber at the bottom;
- a top closure connected to the top of said panels to close the chamber at the top;
- and
- means defining a dispensing flap in said front panel, said means including a frangible perforated line defining a dispensing orifice, said perforated line being formed by a straight portion and two curved portions at opposed ends of said straight portion, said means further including two sets of a plurality of fold lines formed in said front panel, each set contacting said perforated line at said curved portions and extending from such contact to opposite sides of said front panel, with one of said fold lines in each set being tangent to the associated curved portion,
- whereby once said dispensing flap is manipulated to fully sever the perforated line and form the dispensing orifice, pressure applied to said side panels causes said dispensing flap to extend outwardly from said front panel and away from said chamber to expand said dispensing orifice for the pouring out of the contents of said enclosed chamber.
A unitary blank adapted to be formed into a carton having a dispensing flap defining a dispensing orifice comprising:
- a front panel, right and left side panels and a rear panel hingedly connected along parallel fold lines;
- a glue flap extending from one of said rear panel and said side panels;
- four bottom closure flaps hingedly extending from the bottom of said panels;
- first, second, third and fourth top closure flaps hingedly extending respectively from the top of said panels;
- a frangible perforated line in said front panel having a substantially linear central portion and left and right curvilinear side portions on opposed sides of said central portion;
- a right side array of fold lines intersecting each other and contacting said right curvilinear side portion;
- and
- a left side array of fold lines intersecting each other and contacting said left side curvilinear side portion.
