Why are fresh water cans round and not rectangular?

Have you ever wondered if the soft drink cans we drink are not designed in spherical or rectangular boxes?

Why are fresh cans designed with circular cylinders?

Have you ever wondered why the fresh water cans have a round cylinder and not a sphere or a rectangular box? Let's find out the answer through the article below, as explained by Bill Hammack, a professor at the University of Illinois, USA.

If water cans are spherical

Small surface area, saving materials .

Theoretically, round spherical cans will have a smaller surface area, meaning less material is consumed.In addition, spherical cans have no edges, so there is no weakness, because the pressure is spread evenly on the can.

. but can't stand .

However, it would be a big mistake to apply spherical cans in practice because water cans cannot stand on a flat surface.

. and storage and transportation are extremely inconvenient.

Moreover, storing and transporting spherical cans is very inconvenient.Water cans will only slip over and slip, making it difficult to transport.In addition, we will only utilize 74% of the space when stacking spherical cans.

What about the rectangular box?

Large water storage area, standing on all surfaces .

Rectangular cans of water can completely solve the problems of spherical cans.Box-shaped cans for larger water bodies, which can stand firm on the surface, take advantage of 100% of the space when stacked on top of each other.

. but it makes you trouble drinking.

The boxy design will make it difficult to hold the water can, next to the square corner, which can hurt you if you accidentally hit it while drinking.Besides, square corners are the weakness of this design, so more materials are needed to reinforce the corners of the can.

Finally, the most feasible can design comes out - round cylindrical cans

Cylindrical cans were born with a combination of both designs.When viewed from above, the design will look like a sphere.When looking from the edge, the cans will look like rectangular boxes.And just like spherical cans, round cylindrical cans have no weaknesses, as the pressure is spread out evenly into the cans.

The ability to take advantage of the space when transporting cylindrical cans is a bit less than the rectangular box, but is superior to the spherical cans.In addition, a very practical reason makes the manufacturer decide on this design, which is a cylindrical cans that are easier to produce than the other two types of cans.
