FIELD: transport, package.
SUBSTANCE: invention relates to large containers, particularly, to flexible]e tanks for storage and transportation of fluid, including oil products. Soft tank comprises closed polymer envelopment with faces, coat and bottom, as well as fill-and-drain branch pipes. Proposed tank differs from known designs in that closed envelopment is made up of two envelopments with tight chamber there between and interconnected by webs. Note also that air hose is brought from said tight chamber outside the tank to allow forcing air into said chamber to inflate it. Note that inner envelopment is made from PVC and outer envelopment is made from polyurethane at 50%-to-50% ratio.
EFFECT: fast erection, ease of use, higher reliability.
