<p>A bag intended to contain injectable products has two sides, each constituted by a sheet of a complex film and formed so as to have a flat-bottomed, dish-shaped part. At the flat rim of this part, each film sheet is welded to one of the flat surfaces of the semi-rigid reinforcing frame so that the two dish-shaped parts are fitted within each other. Connecting tubes traverse one side of the frame and open out in the central opening of the latter between the two sheets.</p> |
