Abstract: A container for food safe liquids for beverage dispensers, includes a first end, or bottom wall, a second end, or neck, equipped with a portion for releasing the water designed to be connected to a corresponding junction portion of a beverage dispenser and a tubular wall extending annularly along its own main central axis between the first end and the second end. The tubular wall extends along the central axis with a succession of ridges and grooves such a way as to be collapsible along the central axis to reduce its overall dimensions, so as to compensate the negative pressure generated inside the container during dispensing of the liquid preventing contact between the liquid and the air outside the container.
