I actually remember squeeze snacks ... A very 70's thing one would eat while entertaining or watching Graham Kerr's "Galloping Gourmet" on TV.
It's lure was the fact that you could squeeze the imitation cheese food directly onto crackers or celery sticks and it would have a "piped" look to it, as if you used a star tipped piping bag. Lol... classy eh? The built in excluder tip does that for the hand size tube shaped packaging.
We didn't waste any food in the 70's, so one could completely empty the squeeze snack packaging much like a toothpaste tube to get every last drop of the plastic like imitation cheese food goodness
