Abstract
An improvement in a sealed pouch made of molecularly-orientable polymeric film that is sealed along peripheral edge margins is disclosed. The pouch defines a sealed cavity for containment of a fluid. The pouch also defines a sealed fluid-discharge spout that is in fluid communication with the fluid cavity. The pouch further defines a seam disposed between the fluid cavity and the spout. The improvement comprises at least three essential features. One such feature is that a portion of the polymeric film which defines a fluid-discharge end of the spout is molecularly-oriented in a preselected direction. Another such feature is that a portion of the seam defines a slit disposed transverse to the preselected direction. Still another feature is that a portion of the sealed pouch peripheral edge margin in the vicinity of the fluid-discharge end of the spout defines a tear-initiating notch oriented in the preselected direction.
