A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.

A structure in which no shearing force acts on each member is desired to be used at a welded part where a stress is liable to be concentrated. To solve this problem, the flange member includes a cap member, a ring member, and sheet-shaped thermoplastic resin member. At least one end of the thermoplastic resin member includes a protruding part that protrudes from an end surface of the cap member and from an end surface of the ring member. The protruding part is welded to the end surface of the cap member and to the end surface of the ring member.

A process manufactures a padding device (10a; 10b; 10c; 10d; 10e), for a carrying belt system (100) for a respirator (1000), having a closed pad core shell (20) and a pad core (30) configured in the pad core shell. The process includes injection molding a hollow profiled section, inserting of a pad core material into the hollow profiled section for forming the pad core in the hollow profiled section, and closing the hollow profiled section (21) for creating the closed pad core shell (20). The padding device (10a; 10b; 10c; 10d; 10e) has a closed pad core shell (20) and a pad core (30) arranged in the pad core shell. The pad core shell is seamless as an injection-molded component in at least some sections. A carrying belt system as well as a respirator with the carrying belt system are provided with the belt system having the padding device.

The composite tube may include a body having a longitudinal centerline axis and at least one end portion. The at least one end portion may include a plurality of segments that are angled relative to the longitudinal centerline axis and are circumferentially separated from each other by a plurality of slits. The composite tube may be implemented in a joint assembly that includes a support wedge. The support wedge may at least partially engage at least one of a radially inward surface of the at least one end portion and a radially outward surface of the at least one end portion.

The present invention relates to systems and methods to facilitate replacement between runs of a kit or cassette from an automated radiosynthesis device located in a hot cell. The method and apparatus of the invention enable automated disconnection of the outlet line by sealing the tubing hermetically by means of heat and by cutting the tubing where it is sealed in such a way that there is no risk of environmental contamination with radioactive material. The invention enables disconnection of the outlet line without manual intervention before opening the shielded enclosure.
