Abstract: An arrangement for a dropper, in particular a container (bottle) (1) made of injection-molded plastics, preferably, but not necessarily, translucent, with a base (2) having the form of a membrane (M), having a different thickness than the container, but being an integral part of the container (bottle) (1), with a corrugated perimeter (3) that causes the membrane (M) to act like a spring, making it considerably easier to actuate and move the liquid mechanically towards the dose dispensing device (4).
