BOTTLE Russian patent published in 2019 - IPC B65D1/02 

FIELD: container and packing.

SUBSTANCE: bottle contains a neck and a body, including spherical, cylindrical and conical parts connected to each other. Spherical part of the body is made in the form of a sphere associated with the neck and is the upper part of the body. Cylindrical part of the body is made in the form of a straight circular cylinder. Conical part of the body is made in the form of a truncated straight circular cone, the diameter of the lower base of which exceeds the diameter of its upper base. Cylinder is located between the sphere and the cone. Diameter of the cylinder is smaller than the diameter of the sphere. Sphere is made with stiffeners, forming on the surface of this sphere a set of convex spherical polygons, mated with each other so that the side of an arbitrarily chosen spherical polygon is the side of another spherical polygon mated with the specified arbitrarily selected spherical polygon. Diameter of the lower base of the cone is equal to or greater than the diameter of the sphere, and the side surface of the cone is made with stiffening ribs located along axially oriented helix lines.

EFFECT: invention provides the rigidity and strength of the bottle body and the convenience of its grip when using it.
