Abstract

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.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 114 words
A parallelepipedal dispensing package comprising a carton having a plurality of sidewalls and top and bottom closure means, a funnel, a bag-type liner for housing a predetermined quantity of flowable material, said funnel having an outlet end juxtaposed an inwardly facing surface of one of said sidewalls, the interior surface of said funnel having a sufficient degree of taper with respect to the nominal angle of repose of said flowable material that substantially all of said flowable material can gravitate from said package when said package is oriented with said funnel pointing downwardly and when the portions of said liner and said one sidewall which span the outlet end of said funnel are breached.
Claim 2
Dependent Claim 114 words
A parallelepipedal dispensing package comprising a carton having a plurality of sidewalls and top and bottom closure means, a funnel, a bag-type liner for housing a predetermined quantity of flowable material, said funnel having an outlet end juxtaposed an inwardly facing surface of one of said sidewalls, the interior surface of said funnel having a sufficient degree of taper with respect to the nominal angle of repose of said flowable material that substantially all of said flowable material can gravitate from said package when said package is oriented with said funnel pointing downwardly and when the portions of said liner and said one sidewall which span the outlet end of said funnel are breached.
Claim 3
Dependent Claim 34 words
The dispensing package of claim 1, wherein said carton is rectangular and the discharge outlet of said funnel comprises a rectangular opening having its sides oriented substantially parallel to the sidewalls of said carton.
Claim 4
Dependent Claim 47 words
The dispensing package of claim 2, wherein the interior bag liner-contacting surface of said funnel comprises four substantially planar surfaces which intersect one another to form lines interconnecting the interior corners of the dispensing package and the corresponding corners of the rectangular discharge outlet in said funnel.
Claim 5
Dependent Claim 23 words
The dispensing package of claim 3, wherein said rectangular discharge outlet in said funnel is centrally located with respect to said carton sidewall.
Claim 6
