[null and void]

I think you are on to something. That might actually be an interesting way to package milk, tit shaped containers. Hard to believe it has not been thought of before.

I think it's the source of the brand name "Tetra-Pak"

I was thinking more of a rounder perkier package, with a twist off nipple. Or better yet, double containers, with a handle in between, one could be fat free the other whole or 2 percent......maybe they could be produced by “Mammary Farms” or “Dolly Parton” dairies, triple D for short.

Used to buy milk in ta-ta containers like that in Spain and Italy back in the 60’s. The stores shelved it at room temp, not refrigerated.
