The procedure consists of making a tubular body (30) of a rigid material and stamping out a top and base (50,50') from an identical or similar material. The top and base are fitted simultaneously into the ends of the body with a seal (70) inside the top. The two ends are sealed by rolling over the edges (35,35') of the body, and a pre-cut line (32) is made around the upper end of the body and the top to allow the top to be opened while leaving the seal in place. The package is filled with the product before the base is fitted and sealed. |
