A system stores densely dissolved methane-base gas and supplies gas of a predetermined composition. A container (10) stores methane-base gas dissolved in hydrocarbon solvent and supplies it to means for adjusting composition, through which an object of regulated contents is obtained. Preferably, the means for adjusting composition is means for maintaining the tank in a supercritical state, or piping (48) for extracting substances at a predetermined ratio from the gas phase (12) and liquid phase (16) in the container.

A method of packaging by wrapping as claimed in claim 1, characterised in that the top film sheet (65) is pressed onto the object (31) being packaged by means of a pressing device (53) while at the same time lifting the edges of the top film sheet upwards by means of the suction nozzles (55) of the top film sheet carrier (54). 3. A method of packaging by wrapping as claimed in claim 2, characterised in that the top film sheet (65) is gripped by means of suction nozzles (55) and the edges of the top film sheet are pressed downwards by means of blow nozzles. 4. A method of packaging by wrapping as claimed in claim 2, characterised in that the same nozzle (55) is used as a suction nozzle and a blow nozzle, the function of which nozzle is selected by connecting the nozzle duct either to the suction side of the fan or the pressure side of the fan. 5. A wrapping machine (20) for packaging an object (31) to be packaged with a top film sheet (65) and a plastic film web (43) used for wrapping, the wrapping machine comprising: a device (60) for cutting the top film sheet (65) of a desired size from a top film web (64), a device (50) for bringing the top film sheet (65) to the wrapping station, a top film carrier (54) and means (55) for keeping the top film sheet (65) attached to the top film carrier, a pressing device (53) for pressing the top film sheet (65) onto the object (31) being packaged, a gripping means (55) for keeping the edges of the top film sheet (65) lifted up and/or turning the edges downwards onto the sides of the object (31) being packaged, and a wrapping device (40) for wrapping the plastic film web (43) around the object (31) being packaged, characterised in that the wrapping machine comprises means (63) for bringing the top film sheet (65), which is cut from the top film web (64), to the wrapping station over the top film carrier (54) and the pressing device (53), means (52) for turning upside down the top film carrier (54), the pressing device (53) and the top film sheet (65), and means (51) for pressing the upside down turned top film sheet (65) onto the object (31) being packaged by means of the pressing device (53). 6. A wrapping machine (20) as claimed in claim 5, characterised in that the gripping means (55) of the top film sheet (65) carrier (54) are suction nozzles and the pushing means are blow nozzles. 7. A wrapping machine (20) as claimed in claim 6, characterised in that the nozzles (55) of the top film sheet (65) carrier (54) are double acting, so that the same nozzles serve as both suction nozzles and blow nozzles, that the nozzles (55) are connected to the fan by means of a change-over valve in such a way that the nozzles are suction nozzles when the change-over valve connects the nozzles to the suction side of the fan, and that the nozzles (55) are blow nozzles when the change-over valve connects the nozzles to the pressure side of the fan. 8. A wrapping machine (20) as claimed in claim 5, characterised in that a pressing device (53) is attached to the top film carrier (54) of the wrapping machine (20) for pressing the top film sheet (65) onto the article (31) being packaged. 9. A wrapping machine (20) as claimed in claim 8, characterised in that the top film carrier (54) and pressing device (53) of the wrapping machine (20) are located above the rotation ring (41) in such a way that the combined top film carrier and pressing device can be lifted by means of the rotation ring. 0, Foernsler; US-1805119, 19310500, Voigt; US-1818923, 19310800, Taylor; US-1913642, 19330600, Smith; US-2072516, 19370300, Ferenci et al.; US-2227378, 19401200, Milmoe et al.; US-2294273, 19420800, Buxbaum, 271/099; US-2653743, 19530900, Stenger, 053/250; US-2741886, 19560400, Garapolo et al.; US-2821826, 19580200, Stubblefield; US-3797822, 19740300, Anderson, 271/099; US-3868807, 19750300, Noyes et al.; US-3935691, 19760200, Broch; US-3937458, 19760200, Langen, 271/099; US-3952478, 19760400, Richards et al.; US-4182222, 19800100, Stahl; US-4248032, 19810200, Woods et al.; US-4268344, 19810500, Jones; US-4297826, 19811100, Woertche; US-4355967, 19821000, Helmer; US-4418906, 19831200, Scott, 271/099; US-4530200, 19850700, Prewer; US-4649692, 19870300, Tomosue; US-4658564, 19870400, Bell, Jr. et al.; US-4709851, 19871200, Vanasse; US-4815251, 19890300, Goodman; US-4833861, 19890500, Hale et al.; US-4837956, 19890600, Dolence; US-4908761, 19900300, Tai; US-5002313, 19910300, Salvatore; US-5079901, 19920100, Kotsiopoulos; US-5157896, 19921000, Tisma, 053/238; US-5368286, 19941100, Horsman et al.; US-5477662, 19951200, Rompa; US-5481094, 19960100, Suda; US-5483786, 19960100, Giesbrecht et al.; US-5502956, 19960400, Rompa; US-5549233, 19960800, Clauser; US-5645680, 19970700, Rietheimer; US-5680743, 19971000, Hoekzema; US-5727153, 19980300, Powell; US-5737899, 19980400, Supron et al., 053/238; US-5806044, 19980900, Powell; US-5819954, 19981000, Lacriola; US-5826356, 19981000, Lapp; US-5941053, 19990800, Kotsiopoulos, 052/238; US-5941681, 19990800, Piotrowski et al., 271/099; US-6035605, 20000300, Perego, 053/238; US-6434914, 20020800, Bouldin et al., 053/238; US-6470653, 20021000, Lutz et al., 053/238
