FIELD: machine engineering.
SUBSTANCE: bottle is designed for use under low temperature conditions during long-term storage and transportation of liquids, compressed and liquefied gases. The bottle has a liner 1 with coating 2 with reinforcement winding of its cylindrical part 3, bottoms 4, composite necks of upper 5 and lower 6, outer 12 and inner 9 threads. Each of the component necks 5 and 6 of the bottle consists of a primary neck 7 of the liner 1 with outer 8 and inner 9 threads, upper 10 and lower 11 power bushings which are screwed onto the outer thread 8 of the liner 1 primary necks 7. The power bushings 10 and 11 have hexagon beads 14 adjacent to liner bottoms 4. The lower power bushing 11 is provided with two flats 15. There are fixing nuts 16 mounted on the upper and lower necks. The coating 2 of layers of reinforcing fibres and epoxy resins partially covers the power bushings 10 and 11. The thickness ratio of the coating layer of portion of the power bushings 10, 11 to the thickness of the layer of the cylindrical portion of the balloon corresponds to 3: 1.
EFFECT: fixation of the bottle in vertical position after its mouth is provided, bottle rotation in fixed condition around its rotation axis is prevented, removal of condensate from the bottle is provided.
