They sometime are and sometimes not. The milk that I buy is not in a cylindrical container. So the mathematical [logical] analysis of the question is that the premise is false and so the question is not valid.
Having said that, a sphere is the most efficient shape in the sense that a spherical container required the smallest amount of container material (glass or plastic) for the largest volume of the liquid. However, a spherical container is not stable, and the liquid could spill out. The best stable shape is a cylinder.
There are several types of containers used for various purposes, primarily in shipping and storage. The most common types include standard intermodal containers (such as 20-foot and 40-foot containers), refrigerated containers (reefers), tank containers for liquids, and specialized containers for specific cargo (like flat racks and open-top containers). Additionally, there are smaller containers used for domestic shipping and logistics. Each type is designed to accommodate different types of goods and transportation methods.
Volume is a pace which can be occupied by some thing, whereas capacity is applies to liquids as the quantity contained in a given space.
For storing large numbers of containers I think a rectangular shape is more efficient because you can place them side by side with no wasted space between them like you would have with cylinders. I think it depends on how big the containers are (cylinders are easier to roll) and how much space you have, what type of liquid is to be stored etc. as to which shape would be best.
Cylindrical shapes offer structural stability and efficiency in many applications. Their uniform shape distributes stress and weight evenly, making them sturdy and resistant to deformation. Cylinders also have a large volume-to-surface area ratio, which can be advantageous for containing or transporting liquids and gases. Additionally, cylindrical objects are often easier to manufacture and assemble compared to more complex shapes.
The amount of anything a container can hold is it's volume or its capacity.
The symbol for a beaker is a simple cylindrical shape with a lip or spout for pouring. It is commonly used to represent containers for holding and measuring liquids in laboratory settings.
Liquids have the form of the containers.
Because liquids has not a form (as solids).

Liquids have the form of the containers.
Coal and water are held in railcars by using hoppers and tanks respectively. Hoppers are open-topped containers that allow coal to be loaded and unloaded easily, while tanks are cylindrical containers designed to hold liquids such as water. These components are securely attached to the railcar to ensure safe transport.
