| 摘要 |
The present invention relates to a bag-on-valve system (10) comprising a pressure container (12) having a substantially flexible filling material container (14) which is received therein and in which a filling material (22) having unsaturated compounds, preferably terpenes, particularly preferably limonenes, is received and can be removed from the bag-on-valve system (10) by means of a selectively actuatable valve (20), a propellant, preferably a propellant gas, being provided in order to support the removal between the pressure container (12) and the filling material container (14) so that a flexible sheath (16) of the filling material container (14) is in contact with the filling material (22) at the inner side (16a) thereof and is in contact with the propellant at the outer side (16b) thereof, the sheath (16) of the filling material container (14) further being substantially formed from a flexible film laminate (30) which has a metal layer (32), a plastics layer (42) and a thermally sealable sealing layer (38) in the sequence mentioned in the direction from the outer side (16b) to the inner side (16a), wherein the plastics layer (42) is a polyester layer, preferably a layer of aromatic polyester, more preferably a terephthalate layer, particularly preferably a polyethylene terephthalate layer.
