A disposable portion package for a usable product, said usable product being in the form of a liquid, cream, paste, powder or the like, said package comprising two wall means sealed to one another along an overlapping section to thereby define a closed casing in which said product is disposed, one of said wall means comprising an outer stiffening layer means and an inner film layer, a seal weakening material disposed between a portion of said outer stiffening layer means and an overlapping portion of said inner film layer with the remaining portion of said outer stiffening layer means and said inner film layer being overlappingly joined to another, said seal weakening material being overlappingly disposed relative to a portion of said overlapping section of said two wall means, said inner film layer being constructed and arranged such that when external pressure is applied to the package by the user for obtaining access to the usable product, the part of the inner film layer juxtaposed said seal weakening material ruptures and the product exits said package through said rupture in said inner film layer and through a conduit formed between said stiffening layer means and said inner film layer at the portion where said seal weakening material is disposed.
