Abstract
A container has first and second walls, each formed of a thermoplastic sheet having a peripheral edge. A peripheral seal joins the peripheral edges together to form an interior chamber enclosed by the first and second walls. A port communicates with the interior chamber. The port is spaced from and does not extend through the peripheral seal. The port comprises a hollow thermoplastic tube, which extends through a slit in one of the first and second sheets and is oriented tangentially thereto. The slit is fused by heat about the tube, forming a heat fused junction. A medical product or a blood filter material can be housed in the interior chamber.
