ABSTRACT:
A dispensing package comprising a substantially rectangular, parallelepipedal container which is suitable for stacking, a bag-type liner, and an internal funnel having its outlet end disposed adjacent a sidewall of the container so that the contents of the container can be dispensed through its side as opposed to the flap formed, multiple layered top or bottom closure is disclosed. The funnel is provided with a sufficient degree of taper that substantially all of the flowable material contained within the bag liner can gravitate from the package when the package is oriented with the funnel pointing downardly and the portions of the bag liner and the carton sidewall which span the outlet end of the funnel are breached. In a particularly preferred embodiment, the package is made suitable for dispensing particulate material disposed within the bag liner without agitation or manual manipulation of the package by providing the funnel with an angle of taper greater than the nominal angle of repose of the particulate material.
