But would it still be a "can"?

can2 ( P ) Pronunciation Key (kn)
n.

1. A usually cylindrical metal container.
2.
(a) An airtight container, usually made of tin-coated iron, in which foods or beverages are preserved.
(b) The contents of such a container.
3. Slang. A jail or prison.
4. Slang. A toilet or restroom.
5. Slang. The buttocks.
6. Slang. A naval destroyer.

Hmm.. I suppose so. But it just doesn't sound right...

Packaging cost and packing space alotment.

Because a can is essentially a pressure vessel. You always want a round surface so that the pressure is distributed evenly throughout the can. The best shape to contain pressure is actually a sphere, that is why some large natural gas tanks, and the center sections of deep sea submersibles are a sphere.

Bingo. Very expensive to manufacture. Square corners are also hard to seal properly for the top and bottom of the can.

Here's a recent article (sorta) from December 2002..

Voters opt for a square meal
Our recent report of the new square cans being trialled by UK retailers included a survey. We asked if you would favour their introduction in Australia. The response was a bit of a surprise.

The response was an overwhelming "Yes" vote for the square can. Only one person stayed faithful to the traditional round can and voted "No".

We had reported that The UK?s number two supermarket, Sainsbury's, is testing whether the public is ready to buy soup in square-shaped cans.

The square cans with their pull back lid will be sold alongside the traditional round cans, marketed in exactly the same way and containing the same produce, in an attempt to see whether or not people will buy them.

Sainsbury?s believes that the square tins could make significant savings for transportation and storage because they can be stacked more efficiently.

If the trial is successful, the company says that it will start to stock the new square tins in all its stores across the UK.

Grahame Horsfield, Executive Director of the Canned Food Information Service says that the results of our poll has been passed on to the brand owners and the can makers in Australia.

But don't hold your breath! he says. The concept has been alive for some years now and there are still plenty of technological problems to be solved (and marketing risks to be taken) before we can give you the product at the same price as a round can.

By the way, Grahame adds, in all the consumer surveys we have undertaken in the last 15 years, the traditional round can always comes up No. 1 against all other forms of packaging for tamper proof, safety and product integrity.

A cylinder is EXTREMELY stong against vertical forces and uses less metal than a square would.

Because beer and soda are three-dimensional! Har har...

You can convert your round cans into square ones as long as they aren't opened yet. Just stick them in the freezer for a day or 2.

Well, how about a pyramid?
Or maybe sort of an egg shape? That would be very 21st century.

There is a coating on the inside of pop cans that keeps the pop from eating through the can. Having a cylindrical shape makes it much easier to have a sufficient coating to prevent the can from deteriorating. If you were to have square edges, there'd probably be many more cans "failing" so to speak because of the way it would come to a point making it hard to coat it sufficiently. This is why if you dent a pop can that a hole will form in the dent several days later and then the pop will leak out.

Why waste money manufacturing "cans" at all. I want beer coming out of my kitchen sink.
