Bottle with integral dip tube

A fluid dispensing container comprising: a bottle (10) having a front side surface (14), a rear side surface (19), a bottom (18), a top neck (16), a coupling of the bottle under the top of the neck (16) and an inner volume (22), in which an immersion tube (12) is formed integrally outside the front lateral surface (14), separated from the front side surface (14) by a partition (48) and fluidly connected to the inner volume (22) at the bottom; characterized in that: the immersion tube (12) is fluidly connected to the inner volume (22) on a platform (17) below the upper neck (16); and the container further comprises a pressure adjustment fluid dispensing mechanism (40) attached to the neck of the bottle by means of a pressure adjustment connector (44) and fluidly connected to the immersion tube (12) on the platform ( 17), in which the fluid dispensing mechanism includes (i) a supply line (50) that connects directly to the integral immersion tube (12) when the fluid dispensing mechanism (40) is attached to the bottle (10); and (ii) a spring-operated reciprocating pump that discharges fluid through the movement of a piston head; and in which the distance between the upper neck (16) and the platform (17) is equal to or greater than the length (38) of the bottle coupling.
