<p>A SQUARE CONTAINER INCLUDES A CONTAINER BODY (10) HAVING AN UPPER END PROVIDED WITH A REDUCED PORTION (101), AN UPPER SEAL COVER (11) HAVING AN OUTER WALL PROVIDED WITH AN UPPER WINDING RIM (13) COMBINED WITH THE REDUCED PORTION OF THE CONTAINER BODY, AND A LOWER SEAL COVER (14) MOUNTED ON A LOWER END OF THE CONTAINER BODY AND HAVING AN OUTER WALL PROVIDED WITH A LOWER WINDING RIM (14). THUS, THE UPPER WINDING RIM OF THE UPPER SEAL COVER IS FLUSH WITH AND DOES NOT PROTRUDE OUTWARDLY FROM THE PERIPHERAL WALL OF THE CONTAINER BODY BY PROVISION OF THE REDUCED PORTION, SO THAT WHEN TWO SQUARE CONTAINERS ARE STACKED, THE UPPER WINDING RIM OF THE UPPER SEAL COVER OF ONE SQUARE CONTAINER IS RECEIVABLE INTO THE LOWER SEAL COVER OF ANOTHER SQUARE CONTAINER TO OVERLAP AND STACK THE SQUARE CONTAINERS CLOSELY AND STABLY.
