A receptacle of an elastically flexible plastic includes a dosing chamber (10) with a medium to be discharged. One end of the dosing chamber (10) has a discharge opening (18). The opposite end is connected via a junction point (20) to a compressible receptacle part (22) with a gaseous propelling medium. When compressing the receptacle part (22), the propelling medium forces the medium to be discharged out of the dosing chamber (10) via the discharge opening (18). The junction point (20) between the dosing chamber (10) and the receptacle part (22) is a bottleneck creating a capillary effect independent of the spatial position of the receptacle preventing transfer of the medium of the dosing chamber (10) into the receptacle part (22).

1. 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; anda 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. 2. A receptacle according to claim 1 wherein said support arms extend along a separating plane along which halves of the receptacle abut one another and at least partially overlap said separating plane. 3. A receptacle according to claim 1 wherein said support arms have an extension on ends thereof facing away from said dosing chamber transitioning into a tab having coding thereon. 4. A receptacle according to claim 1 wherein said dosing chamber is tubular; andsaid receptacle part is essentially cuboidal. 5. A receptacle according to claim 4 wherein said receptacle part projects at least in one direction over said second end of said dosing chamber. 6. A receptacle according to claim 1 wherein volumes of said receptacle part to said dosing chamber have a ratio of at least 2:1. 7. A receptacle according to claim 1 wherein a removable twist closure closes said discharge opening prior to opening thereof and discharge of said delivery medium. 8. A receptacle according to claim 1 wherein said dosing chamber tapers at least in increments toward said discharge opening. 9. A receptacle according to claim 1 wherein said delivery medium is a liquid. 10. A receptacle according to claim 1 wherein said delivery medium is an ointment fluid. 11. A receptacle according to claim 1 wherein the capillary action of said capillary tube also prevents flow of said propellant medium into said dosing chamber without compression of said receptacle part. 12. A receptacle according to claim 1 wherein said dosing chamber, receptacle part, support arms and capillary tube are integrally formed of elastically flexible plastic. 13. A receptacle according to claim 1 wherein said capillary tube is a cylinder.
