The invention provides a container see-through device and a fabricating method thereof. A container is punched to form a see-through window hole, and a see-through window is tightly attached to the periphery of the see-through window hole. The container see-through device is characterized in that protrusions are formed on the periphery of the see-through window hole, the periphery of the see-through window hole is flanged towards the inside of the container so as to form bend angles between the protrusions and container walls which are connected with the protrusions, and the see-through window is slightly larger than the see-through window hole. The protrusions formed on the periphery of the see-through window hole are in a zigzag shape, the periphery of the see-through window hole or the periphery of the see-through window is heated by a heating device, then the see-through window is extruded from inside to outside, the zigzag protrusions are heated to high temperature, and then the see-through window is extruded into the zigzag protrusions. The container see-through device and the fabricating method thereof have the advantages that the technological process and the structure are simple, the operation is convenient, and costs are low.
