A square milk jug has lots of benefits; because of its square shape, they stack more efficiently compared to existing milk jugs. The shape makes it so that cartons of milk won’t require milk crates. The net result is reduced transportation costs.
However, it seems they are not so easy to pour. According to the NYT article, training was required to show shoppers how to pour without spilling.
Mary Tilton tried to educate the public a few days ago as she stood at a Sam’s Club in North Canton, about 50 miles south of Cleveland, luring shoppers with chocolate chip cookies and milk as she showed them how to pour from the new jugs.
“Just tilt it slowly and pour slowly,” Ms. Tilton said to passing customers as she talked about the jugs’ environmental benefits and cost savings. Instead of picking up the jug, as most peopletend to do, she kept it on a table and gently tipped it toward a cup.
The fact that training is required makes this jug seems like a lazy design. There must be a simple design solution that keeps the benefits of square milk jugs but makes pouring “intuitive”?
