Nominal (working) volume of the vessel. In fact, the largest amount of liquid that can be poured inside without problems, without filling the container “to the very cork” and without risking spilling the contents upon subsequent opening. Accordingly, the volume is indicated with a margin; most bottles and flasks allow for slightly more liquid than is nominally stated, however this is not recommended.
A capacious vessel allows you to carry more drink with you, but it takes up more space, and it will weigh (especially when filled) accordingly. Therefore, when choosing, it is worth considering the features of the planned application. In addition, certain types of flasks and bottles have their own volume requirements: for example, in classic flasks (see "Type"), the volume rarely exceeds 300 mL, and bicycle flasks hold about 600 – 700 mL, because. a larger vessel would be difficult to carry on a bike rack.
The container has a graphic marking of displacement. The measuring scale allows you to more accurately plan the distribution of the liquid. Such a container can be useful during all kinds of hikes and trips to places where access to drinking water is limited.
Scaled flasks and bottles are often the choice of athletes and active lifestyle enthusiasts. Usually, the marking step is 100 or 250 mL.
