My memory of milk containers of the 1950's was a square one made of waxed cardboard that had a seam at the peak of a ridge on the centerline of the top. To open, you spread apart the seam on the side marked "open" and then fan out the resulting wings. By manipulating the "wings" you then got the center section to extend out into a v-shaped spout. The spout folded up but didn't reseal the carton. These came in pints, quarts, half-gallon, and gallon sizes. There was a miniature version for school lunches/single servings.
