A closure comprising a spout and a lid is secured to a wide mouthed container body, particularly a low tolerance HDPE container, by means of a plurality of double sided foil strips that are punched and welded to the base preferably in orientations parallel to one another on opposite sides of the opening and/or at right angles to each other. The strips are secondarily welded to the container to form a childproof, tamper-evident connection superior to mechanical latches and uses less material than a full or donut foil.
