Watering bag for animals e.g. cows, has contour whose three broken lines formed according to angles with opposite signs, where form of contour is symmetrical with respect to symmetry plane and compared to another symmetry plane

摘要

The bag has a contour including three broken lines (S1-S3) according to angles (alpha, beta) having opposite signs, where the bag is provided with a conical shape base plate. The contour is in the form that is symmetrical with respect to a symmetry plane and symmetrical compared to another symmetry plane, where the latter plane is perpendicular to the former symmetry plane.
