A convenience container with a cornered bottom is comprised of an outer shell and a pouch sealed to the inside of the outer shell for containing a liquid. The outer shell is provided with fold lines and with a scored line for forming a mouth opening. The outer shell is pressed inwardly along these fold lines, and the top marginal portion of the outer shell is cut off along the scored line, to thereby easily form an opening to serve as a dispensing mouth.

A method for making a convenience container having a cornered bottom, comprising: (a) forming a pounch by: (i) providing a generally rectangular blank of flexible pouch material, and folding that blank into the form of a pouch that is medially W-shaped in vertical cross-sectional shape, along three substantially parallel, laterally extending lines so as to superimpose both ends of the blank along the upper margin of the pouch form and so as to dispose the central one of the three fold lines as a single top fold line located intermediate the height of the pouch form and the other two of the three fold lines as two bottom fold lines located at the bottom edge of the pouch form, thereby defining an outer front panel, an inner front panel, an inner rear panel and an outer rear panel; all four of these panels having superimposed left margins and superimposed right margins although the left and right margins of said inner panels are not as tall as the left and right margins of said outer panels; (ii) sealing the left margins of said outer panels to one another therealong above said single top fold line and sealing the right margins of said outer panels to one another therealong above said single top fold line; (iii) sealing the outer front panel to the inner front panel at the left and at the right, and the outer rear panel to the inner rear panel at the left and at the right, along four respective oblique lines each running obliquely upwardly generally from the bottom edge of the pouch form from a point substantially short of half way across the width of the pouch form, to the respective side margin of the pouch form; (b) forming a blank for a flexible outer shell for the pouch by: (i) providing a generally rectangular blank of flexible outer shell material having a height which is substantially equal to the height of said pouch, and a width which is somewhat greater than twice the lateral distance across said pouch neglecting the sealed side margins of the pouch; (ii) providing two substantially vertical fold lines on said rectangular blank flexible outer shell material intermediate the width of said rectangular blank, these two fold lines being laterally spaced from one another by a distance which is substantially equal to the lateral distance across said pouch neglecting the sealed margins of the pouch; (iii) defining three bonding strips on said rectangular blank of flexible outer shell material, including a first one extending laterally along the upper margin thereof, a second one extending laterally along the lower margin thereof, and a third extending vertically along one side margin thereof; (c) assembling the pouch with a flexible outer shell, (i) superimposing said pouch upon said rectangular blank of flexible outer shell material so that the bottom edge of the pouch is superimposed on the second bonding strip, the sealed left margin of the pouch lies to the left of the leftmost one of said two substantially vertical fold lines, the sealed right margin of the pouch lies to the right of the rightmost one of said two substantially vertical fold lines, and the upper margin of the outer rear panel of the pouch is superimposed on the first bonding strip; (ii) activating the first, second and third bonding strips; and (iii) sequentially doubling over said rectangular blank of flexible outer shell material along said two substantially vertical fold lines, so as to perimetrically enclose said pouch with said rectangular blank of flexible outer shell material, bond said pouch to said blank along said first and second bonding strips and bond said rectangular blank of flexible outer shell material to itself along said third bonding strip, (iv) providing four generally vertical container-assembling fold lines on said rectangular blank of flexible outer shell material, each extending upwards from the bottom edge of said rectangular blank of flexible outer shell material at a given lateral distance respectively to the left or the right of one or the other of said two substantially vertical fold lines laterally to the vicinity of said first bonding strip, said given distance being substantially equal to the lateral distance from where each of said four respective oblique lines intersects the bottom edge of said pouch at the respective said point, to the respective sealed side margin of the pouch, neglecting the width of the respective sealed side margin of the pouch, and thereby defining a generally flat fronted/flat backed, open topped/closed bottomed article which may be filled through its open top, in connection with medially bulging its front and back away from one another along said four generally vertical container-assembling fold lines and moving said two substantially vertical fold lines laterally towards one another at least below said first bonding strip, and bulging the bottom of the pouch centrally downwards along said single top fold line to provide a generally flat, cornered bottom of the pouch.
