Claim:
1. A liquid pressure reducing unit for bringing in fluid communication with the ambient atmosphere a liquid contained in a pressurized container and for gradually decreasing the pressure of the liquid as the liquid is being dispensed, the unit comprising: (a) a first half body comprising a contact surface and a first groove extending over the contact surface; (b) a flexible resilient sealing element comprising a floor layer lining a floor of the first groove; and (c) a second half body comprising a contact surface and a first and second opposed walls extending out of the contact surface and defining therebetween a second groove, the contact surface of the second half body is joined to the contact surface of the first half body, wherein the first and second opposed walls penetrate into the first groove such that a free end of each of the first and second opposed walls form a fluid-tight contact with the flexible resilient sealing element floor layer lining the floor of the first groove, thus defining a fluid-tight channel bringing in fluid communication a fluid inlet with a fluid outlet, the channel being non-rectilinear and/or having a cross-section varying over the length thereof.
