Answer:

To allow easier gripping.

To allow easier, denser packing in dispensing machines.

To avoid sharp edges that might cut hands.

Circular surfaces can easily distribute internal pressure. In addition, surfaces with edges could develop fractures due to high stress at the edges.

Cylinders provide the maximum volume for the least surface area and this saves metal costs. Only spheres are better than cylinders in this regard, but they are impractical.
