A bottle for liquid contains a housing, cross section of which has circular shape different from round shape, a ball and cylindrical neck with locking ring. The housing has a form of truncated cone formed by generatrix, convex with large variable radius of curvature, the larger base of cone is the bottom of bottle, and neck is located on the smaller upper base of truncated cone, in the housing, at least, two cuts are made oriented upward from the larger base, depth of which is greater than the thickness of the wall of housing, moreover the cuts are located evenly on the circumference of housing, the apexes of cuts are located on the level or lower than the smaller base of truncated cone, and the surfaces of cuts have relief projections elongated upward.
