1,190,082. Packaging liquids. SELFPACK G,m.b.H, 13 July, 1967 [28 Sept., 1966], No. 32361/67. Heading B8C. A process for making packages, which may be tetrahedral or cubic, from a tube containing the liquid to be packaged, is characterized in that the liquid in the tube has a gas with inert or sterilizing or preserving qualities dispersed within it to form a homogeneous mixture. After cross-welding and separation of the packages from the tube, the gas will separate out from the liquid to form a compressible cushion, thus removing the risk of the package bursting if the liquid is frozen. The gases which may be used are: the rare gases, ethylene oxide, nitrogen, and chlorofluoro compounds of methane or ethane. |
