Abstract: A liquid container has a neck in fluid flow relation between a hollow body and a mouth. The neck has a flexible portion (a) that can be tilted relative to the axis, (b) through which the hollow body longitudinal axis extends, and (c) that enables the neck to move longitudinally in the direction of the axis. The neck has a bulbous shaped upper portion having a lower edge. The edge and an upper edge of the flexible portion have an intersection with a perimeter less than the perimeters of the adjoining parts of the bulbous shaped and flexible portions.
