10 Criterias to Judge a Good Milk Container

#1 Openability	BAD This container is difficult to open. It require, at first to remove the blue cap. Then there is a small handle that need to be pulled. Sometime it breakes and the pulling action, due to the strenght required, may make you spill some milk	GOOD This container is Easy to open knowing the method. Can be opened with two single steps using one hand while the other hold the bottle. The moviment are slow and would not cause any spill
#2 Closability	BAD The cup net to be screwed to close so it requires some work. It is a separate object that can get lost. It doesn't seal the container ermetically but it gives the false impression that it does so someone may try to store it horizzontally causing milk to spill	GOOD To close the container it is enough to fold it back. It doesn't seal ermetically but it is close enough

#3 Pourability	MEDIUM The flow can be controlled quite accurately but the aperture is wide and round so cannot be pored easily in small container, like expresso cup	GOOD The V shape aperture allow to control the flow accurately
#4 Easy to recognize if open	BAD When you have two or more of these container aligned in the fridge I challange you to understand which one is open	GOOD Open containers can be understood from a quick visual inspection
#5 Recyclability	BAD Even of the recycling regulations change location by location, mixed material product is more difficult to recycle	GOOD Single material container
#6 Holdability	MEDIUM The bottle is almost round shape and the materia is not so strong so holding it, especially when it is full, ma not be that simple	GOOD The bottle is square shape so easy to hold
#7 Emptiability	GOOD All the milk can be poured out of the bottle without trouble. Other shaped container with caps have a problem of keeping part of the liquid due to a small internal edge to connect the cap's skrew. For example this one:	GOOD No problem removing all the milk from this container
#8 Recognizability	MEDIUM This type of container may be associated to some soap container or some other chemical product. It is true that nowadays container are being used for different products	GOOD This has more the shape of a typical milk container
#9 Producibility	BAD Similar to Recyclability, being multi-material seems more difficult and costy to produce. There is also the cap that need to be created separately and added later	GOOD The structure is created that folding and sealing one single peace of material
#10 Honesty	MEDIUM This criteria is not about the shape or material of the container but about the message printed on it. Gradually cows and direct milk imaginery is disappearing from milk container making more difficult to reconize it	BAD The name of this milk is "Oishiigyunyu" that means "Good Milk". This is a misleading message. In Japan moreover they have many product that are not real milk and the only way to figure this out is to be able to read the small text "牛乳" on the envelop. Several Japanese that I talked to, didn't know about this
