PCT No. PCT/SE91/00121 Sec. 371 Date Aug. 6, 1992 Sec. 102(e) Date Aug. 6, 1992 PCT Filed Feb. 20, 1991 PCT Pub. No. WO91/14623 PCT Pub. Date Oct. 3, 1991.A method for manufacturing a container filled with a product is disclosed. The container has a substantially tubular body portion of thin-walled plastic or laminated plastic material and a butt-weldable end-piece at each end of the body portion. A first end-piece is fitted to one end of the body portion and the product is introduced into the container via the open end of the body portion, a second end-piece 13 is introduced into the open body portion end to an intermediate position at which it partially projects into the body portion, and the plastic material of the body portion end region and the second end-piece is softened through application of heat energy. The end-piece by means of relative displacement between it and the body portion, is pressed into the body portion to its terminal position during evacuation of air from the interior of the container via an opening in the end-piece and the opening is thereafter heat-sealed. |
