Who invented bag in the box? And where?

Who first placed wine in an animal skin bladder is uncertain, but it is certainly the distant forerunner of the bag-in-box. Snow skiers in the 1960s and 1970s were often seen holding a bota bag of wine up in the air with a stream of red wine running into their mouth, or occasionally down their chest. These were a modern-day take-off on the goat skin bags used by early shepherds or other travellers, the more recent ones being lined with rubber.
Although many people and companies saw the benefits of placing wine in pouches within cardboard containers, it was Australian Tom (Thomas William Carylon) Angove (1917–2010) who is credited with inventing the bag-in-box for wine, or as he marketed it, the wine cask (Lower, 2010).
