Abstract
A precompression system for a liquid dispensing device is presented, that prevents liquid from being discharged until a predetermined pressure has been built up. The system comprises a pump for drawing liquid through an inlet and discharging it through an outlet, and a precompression valve disposed between the pump and the outlet. The valve allows liquid in the pump to reach the outlet once the predetermined pressure is established, and stops liquid from reaching the outlet once the pressure falls below it. The precompression valve comprises an elastic diaphragm normally closing the valve opening, with a concave surface facing the valve opening and in fluid communication with the pump and a convex surface in fluid communication with atmospheric pressure. The diaphragm may be stretched around a valve seat. Methods of assembling such a precompression system in a dispensing device are also presented.

Abstract
The invention relates to a precompression system (7) for a liquid dispensing device (1), which prevents liquid from being discharged until a predetermined pressure has been built up. The precompression system comprises a pump (3) for drawing liquid through an inlet (5) and discharging it through an outlet (6) and a precompression valve disposed between the pump and the outlet. The precompression valve allows liquid in the pump (3) to reach the outlet (6) only after the predetermined pressure is established. The precompression valve comprises an elastic diaphragm (32) normally closing the valve opening (30) and including a concave surface (32a) facing the valve opening (30) and in fluid communication with the pump and a convex surface in fluid communication with atmospheric pressure. The elastic diaphragm (32) may be stretched around a valve seat (31). The invention further relates to a method of assembling such a precompression system in a liquid dispensing device.

Abstract
The invention relates to a dispensing device comprising a container (2) with a neck (3) and a dispensing head (5) connected to the neck, wherein the neck and' the head have co- acting snap-coupling means (6, 7, 8, 9) which comprise at least three protrusions (6, 7) arranged on one of the two components for connecting, and at least one edge (8, 9) which is arranged on the other part and which co-acts with the protrusions. According to the invention the protrusions are herein distributed non- uniformly as seen in peripheral direction of the neck. Two of the three protrusions can particularly have a substantially equal distance relative to the third protrusion, this distance being greater than their mutual distance. The edge can be divided into a number of edge segments (8, 9) corresponding to the number of protrusions, wherein the edge segments co-acting with the two protrusions (6) located at equal distances relative to the third protrusion (7) can each form part of a boundary of a recess receiving the associated protrusion.
