Thermoformed flexible stand-up dispensing package with integral pour spout

A highly flexible thermoformed stand-up dispensing package for a flowable material, the package produced from one or more highly flexible heat-sealable polymeric sheets, the package comprising:

• a. a bottom sheet thermoformed into a container portion that includes a recessed chamber having a trapezoidal bottom wall and integrally formed opposing side walls, a top wall and a base wall parallel to the top wall, where at least one of the side walls forms an included obtuse angle with the base wall, the chamber being bounded by an outwardly extending peripheral area, the chamber being configured and dimensioned to receive the flowable material, and
• b. a top cover sheet superposed on, and heat-sealed to the periphery of the bottom sheet to form a trapezoidal front wall,
• wherein the opposing side walls are generally trapezoidal or triangular and the narrow end of the trapezoid or the apex of the triangle defines the top wall of the recessed chamber, and the opposite end of each of the side walls defines the base wall, the base wall being dimensioned to maintain the center of gravity of the flowable material in the package over the base wall due to the deformation of the highly flexible walls under the outward force of the flowable material when the base wall of the filled package is in contact with a horizontal surface, and where a predetermined portion of the corner of the package formed by the intersection of the top wall and the projecting side wall that extends at an obtuse angle from the base is removable to provide an opening to dispense the flowable material in the package.
