Abstract: A container assembly includes a container body, a magnetic display panel, a magnetic pen, and a magnetic eraser. The magnetic display panel is mounted on an outer wall surface of the container body, and has a rear side confronting the container body and an opposite front side. The magnetic display panel has a multi-cellular configuration, and includes a cell array and a dispersion contained in the cell array. The dispersion contains magnetic particles. The magnetic pen is used to move the magnetic particles in the cell array to the front side of the magnetic display panel so as to form an image thereat. The magnetic eraser is used to move the magnetic particles in the cell array to the rear side of the magnetic display panel so as to erase the image formed by the magnetic particles at the front side of the magnetic display panel.

Abstract: A container includes a wall body having a projection extending inwardly from the internal wall surface of the wall body and a cavity extending inwardly from the external wall surface of the wall body into the projection with an opening which is located at the external wall surface. A rotatable member is rotatably and unremovably received in the cavity. A portion of the rotatable member protrudes out from the opening of the wall body. Whereby, the rotatable member can be rotated by a user's fingers so as to enhance the aesthetic quality of the container.
