In a method of constructing a reinforced pail from an existing pail having a covered top, an annular ring is formed from a top portion of the side wall by removing the top cover and cutting the side wall around a periphery parallel to the top end of the existing pail, thereby forming a modified pail. The annular ring is then slid as a concentric sleeve over the modified pail to a position where it snugly engages and reinforces the modified pail. The ring is then secured to the pail in such position. |
