The container (1) has gripping units (2) that are fixed and connected to a body of the container. The gripping units are projected with respect to an external surface of the container, where the gripping units include male bodies (21) that are mutually engaged with female bodies (30) intended to be returned back. The female bodies are rotated to ensure blocking around the male bodies, where the male bodies comprise a triangular form extending in a plane parallel to surface of the container. |
