Abstract
A bag for mixing powdered skim milk. The bag comprises an outer, conventional flexible dairy bag for holding milk to be distributed commercially. The bag is formed from sheets of plastic, heat sealed along adjacent peripheral edges. An opening is provided through which to fill the bag, the opening provided with a cap or a flexible spigot through which milk within the bag is to be dispensed. The bag further comprises an inner bag of tubular shape made of a frangible plastic sheet and heat sealed along at least two common adjacent seams with the outer bag so that the non-heat-sealing of one of the common seams, when the inner bag is in position, provides external access for filling the inner bag while the inner bag volume remains separated from the outer bag volume.
