Abstract: A port is formed in a thermoplastic container wall by slitting the wall, inserting a thermoplastic tube through the slit, placing a mandrel in the tube, placing opposed dies defining a bore over the sheet and tube, and dielectrically heating the thermoplastic to fuse the tube and sheet. Preferably the bore defined by the dies is of a diameter slightly less than that of the tube, and has an enlarged central area which forms a thickened section of material over the slit.

Abstract: A blood filtration device encapsulates a filter pad assembly Within a flexible housing. The filter pad assembly includes first and second filter media layers. A first heat and pressure sealed region integrally bonds the peripheries of the first and second media layers together. The flexible housing comprises a peripheral rim aligned with the first heat and pressure sealed region of the first media layer. A second heat and pressure sealed region, formed after the first heat and pressure sealed region, joins the rim of the flexible housing to the first heat and pressure sealed region, thereby forming a composite seal that encapsulates the filter pad assembly within the housing.

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.

Abstract: A blood filtration device (16) encapsulates a filter pad assembly (20) within a flexible housing (18). The filter pad assembly (20) includes first and second filter media layers (44, 46). A first heat and pressure sealed region (28) integrally bonds the peripheries of the first and second media layers (44, 46) together. The flexible housing (18) comprises a peripheral rim (34) aligned with the first heat and pressure sealed region (28) of the first media layer (44). A second heat and pressure sealed region (32), formed after the first heat and pressure sealed region (28), joins the rim (34) of the flexible housing (18) to the first heat and pressure sealed region (28), thereby forming a composite seal that encapsulates the filter pad assembly (20) within the housing (18).

Abstract: A flexible, three-dimensional container is made by a prescribed vacuum-molding and heat sealing process. The container possesses a precise, defined geometry before and during use. The container is formed from first and second walls. The first wall has a planar area and a vacuum-molded cavity area drawn out of the plane of the planar area into a predefined three-dimensional geometry. A second wall overlies the first wall to close the cavity area and thereby forms an interior compartment. A thermal seal joins the two walls together. The seal is formed by heating the second wall and the first wall in the planar area, while assuring that the cavity area of the first wall is not subject to heating and possible deformation of its precise vacuum-molded geometry.

Abstract: A port (20) is formed in a thermoplastic container wall (22) by slitting the wall (22), inserting a thermoplastic tube (26) through the slit (24), placing a mandrel (34) in the tube, placing opposed dies (30, 32) defining a bore over the sheet (22) and tube (26), and dielectrically heating the thermoplastic to fuse the tube (26) and sheet (22). Preferably the bore defined by the dies (30, 32) is of a diameter slightly less than that of the tube (26), and has an enlarged central area which forms a thickened section (40) of material over the slit (24).
