Machine Bottles Milk in Paper (May, 1933)
Those look exactly like modern milk cartons, I wonder why it took so long for them to catch on.
Machine Bottles Milk in Paper
Wrapping milk or cream in paper is the unusual feat performed by a new machine for dairies. In one continuous operation, the device forms a container from paper, dips it in molten paraffin, cools it, fills it with milk, and seals it. A consumer receives a boxful of milk untouched by human hands in the packaging process. The paper containers are easily handled and occupy little space in a refrigerator. They are thrown away when empty. The new containers are a substitute for present-day milk bottles of glass, which must be washed and sterilized for re-use, and which are often lost or broken.
