Who designed those fantastic budweiser canbottle/bottlecans

Sorry, it's not me.

if u are genuinely intrested to start a manufacturing project for beer cans, we can build the project for u on a turnkey basis. mail us at mescotc@sancharnet.in

They are probably spun aluminum... Visa Vie:

Crown Cork & Seal, American National Can, Ball and several other companies have awesome abilities to produce aluminum beverage containers in various shapes and sizes. Check the container you have and somewhere on the outside surface you should see a small logo (i.e. - a crown, initials or a full word) that will tell you who produced the container.

These containers are produced in very large quantity and have to meet rigorous quality and traceability requirements for the FDA and other regulatory agencies. At the same time, there are enormous cost pressures since the soft drink and beer market are highly competitive (thank you, Walmart!). At one time there was quite a bit of engineering effort placed on reducing the 'neck' size (upper lip) of the can because that meant a smaller 'lid' (the part with the flip top) could be used. Reducing that lid circumference by even a millimeter had significant cost saving implications.

It would be interesting to know if the container industry has developed a new standard or whether this intriguing design, albeit costly, generates sufficient market interest that cost is no longer the driving issue and style rules the moment. My hunch is that these new can/bottles will be reserved for special situations.

PS: If you ever have a chance to visit one of these facilities, jump on it. It is fascinating to see a small disk of aluminum that is pressed (or drawn) into the shape of the can and the subsequent cleaning, coating and processing steps. It is all done at very high speeds and is one of the most chaotic environments where I have worked.

Ditto the little folded waxed paper boxes that contain juice or some such other drink. They actually start with a very big roll of flat packaging material, and build the box AROUND a stream of drink liquid. They waste a bit of drink at the start of the process, but once the initial box is sealed, the process is quite efficient.
