Abstract
A novel fabricated tube construction includes a sleeve formed from a stock material and a plastic neck member which includes a shoulder. The sleeve has overlapping edges which are joined together to form an lap seam. The neck member shoulder includes a mounting portion which has at least one raised, plastic weld rib thereon. An end portion of the sleeve initially overlays the shoulder such that the lap seam of the sleeve overlays the raised weld rib on the mounting portion. As a result, a small void is formed between the lap seam and the mounting portion. When the sleeve and the shoulder are joined together, the raised, plastic weld rib on the mounting portion melts and flows into the void to fill and seal the void. A portion of the mounting portion also melts to form a seal between the shoulder and the sleeve. When the shoulder and the sleeve are joined together in this manner, a leak-proof seal or joint is formed around the entire periphery of the shoulder between the shoulder and the sleeve.
