A beverage can, is a container manufactured from aluminum or steel
designed to hold a single serving of a beverage. Beverage cans are also
made of tinplate: see tin can
Cans are filled before the top is crimped on. The key engineering issue
is that can walls are about 90 micrometers thick, so empty cans are
light, weak, and easy to damage. The filling and sealing operations
need to be extremely fast and precise. The Water Filling Machine
can using gas pressure, purges the air, and lets the beverage flow down
the sides of the can. The lid is placed on the can, then crimped in two
operations. A seaming head engages the lid from above while a seaming
roller to the side curls the edge of the lid around the edge of the can
body. The head and roller spin the can in a complete circle to seal all
the way around. Then a pressure roller with a different profile drives
the two edges together under pressure to make a gas-tight seal. Filled
cans usually have pressurized gas inside, which makes them stiff enough
for easy handling.
There were once cans in the United States called cone tops and
crowntainers which had tops that were conical, rather than flat. Cone
top cans were sealed by the same caps that were put on bottles. There
were three types of conetops — high profile, low profile, and j-spout.
The low profile and j-spout were the earliest, dating from about 1935,
the same as the flat top cans that had to be opened with an opener. The
crowntainer was a different type of can that was drawn steel with a
bottom cap and the favorite of some collectors. Various breweries used
crowntainers and conetops until the late 1950s, but not every brewery
used every variety mentioned above. Crowntainers were developed by
Crown Cork & Seal, now known as Crown Holdings, Inc., a leading beverage packaging and beverage can producer. This design returned to use in 2008 for packaging Coca-Cola's Caribou Coffee beverage.
