I bought this brick of pineapple juice the other day (because it was half price) and got a pleasant surprise to note that unlike similar milk bricks it was dead simple to open, with the added bonus of without needing special care to avoid spillage, just simply twist.
It has an inbuilt one shot only barbed sled to break the seal, brilliant.

My first job after leaving school was in the Golden Circle cannery 40 years ago, the noise was monumental with my ears ringing for hours afterwards, luckily I suppose it was only casual work so I was able to find a quieter job immediately that short term was over.
