I'll pay that one RM :Y:
The answer I was looking for was wine cask. According to wikipeda
"The process for packaging 'cask wine' (box wine) was invented by Thomas Angove of Angove's, a winemaker from Renmark, South Australia, and patented by the company on April 20, 1935.[4] Polyethylene bladders of 1 gallon (4.5 litres) were placed in corrugated boxes for retail sale. The original design required that the consumer cut the corner off the bladder, pour out the serving of wine and then reseal it with a special peg[5] and was based on a product already on the market, which was a bag in a box used by mechanics to hold and transport battery acid.[6]
In 1967, Australian inventor Charles Malpas and Penfolds Wines patented a plastic, air-tight tap welded to a metallised bladder, making storage more convenient. All modern wine casks now use some sort of plastic tap, which is exposed by tearing away a perforated panel on the box. For the next decades bag in a box packaging was primarily preferred by producers of less expensive wines as it is cheaper to fabricate and distribute than glass bottles."
Your turn, I can relax now :lol: :lol:
