Claim:
A receptacle of elastically flexible plastic material, comprising: a dosing chamber containing a delivery medium and having opposite first and second ends; a discharge opening at said first end of said dosing chamber; a compressible receptacle part containing a gaseous propellant medium and coupled at said second end of said dosing chamber via a connecting point connecting said dosing chamber and said receptacle part in fluid communication, said connecting point being a capillary tube creating a capillary action independently of relative three-dimensional locations of said dosing chamber and said receptacle part to prevent flow of said delivery medium into said receptacle part; and a support device stiffening said capillary tube, said support device including at least two bridge-shaped support arms extending along at least part of a length of said receptacle part, all of a length of said capillary tube and at least part of a length of dosing chamber; whereby upon compression of said receptacle part, said propellant medium displaces said delivery medium out of said dosing chamber via said discharge opening.
