摘要： PROBLEM TO BE SOLVED: To maintain an accuracy of a shape of a mouth of a container high by shaping a mouth shape of the container from an inside of a parison, and simultaneously blow molding a shape of a container body via a blowing pin. SOLUTION: A mouth 11 of the sterile container is shaped by a mold 2 and an inner mold 3, and a container body is blow molded via a blowing pin. Thus, an accuracy of the mouth shape of the container is improved. Accordingly, a container mouth diameter (r), a mouth thickness TV and a container mouth flange thickness TH are always not only averaged but also a mouth flange (a) can ensure its smoothness. To seal the thus molded container body, after the blow molding is completed, the mold 3 is drawn out, and a sealer is formed by using a parison attached to the mouth end. In the thus obtained container, the mouth shape of the container having a high dimensional accuracy is obtained, at the time of capping after a content liquid is charged, it is not necessary to obtain an excess molten state at a flange surface, but a manufacturing speed can be improved.

摘要： PROBLEM TO BE SOLVED: To efficiently secure the outer diameter accuracy of a narrow diameter section of a convergent multi-lumen tube and the inner diameter accuracy of a plurality of holes. SOLUTION: A molding method for a thermoplastic tube, in which an end of the thermoplastic tube 11 with holes is drawn finely, is constituted of a process of inserting core bars 12A, 12B and 12C having the outer diameter smaller than the diameter of holes and longer than the length of an end 2 of the thermoplastic tube 11 after being molded into the holes of the thermoplastic tube 11, a process of heating a cylindrical die 13 with an introduction opening 13a of the conical shape to the given temperature and a process of passing the end of the thermoplastic tube 11 into a smallest inner diameter section 13b of the heated molding die 13 to draw the outer diameter of the end finely to the inner diameter dimension of the smallest inner diameter section 13b.

摘要： PROBLEM TO BE SOLVED: To simplify and automatize the production of a tube by a method wherein a partitioning wall is mounted to a mandrel so as to fit a tube on the mandrel in order to weld the edge part of a second portion of the partitioning wall to the inside surface of a tube head and finally the longitudinal edge part of the first portion of the partitioning wall is welded to the inside surface of the tube. SOLUTION: With an installation device 14 on a rotary table 10, first of all, a partitioning wall 15 is mounted at the slit of a mandrel 12. Next, a pre- assembled tube 16 is coveringly fitted onto the mandrel 12. The partitioning wall 15 has a nearly square first portion 54. In the tube 16, the width B1 of the portion 54 corresponds to the diameter of the tube plus excess parts (or flanges 45). In addition, its length L1 is made equal to the length of the tube 16. The shape of the second portion 55 connecting with one end part of the portion 54 is set to be the shape of the interior of a tube head 22. With a welding device 20, the flanges 45 of the partitioning wall 15 are welded to the inside surface of the tube in the neighborhood of the longitudinal edge parts of the partitioning wall 15.

摘要： PROBLEM TO BE SOLVED: To suppress the wear of a casting mold and arbor and to necessitate the mere exchange of only a worn tool in spite of wearing by mounting a tubular catheter at this arbor, mounting the arbor at the heated casting mold, molding the catheter, inserting the finned catheter into a jig and cutting fins. SOLUTION: The tubular catheter 1 consisting of polytetrafluoroethylene, etc., is mounted at the coaxial arbor 2. The arbor 2 is inserted to the inner side of the bore 3 of a catheter cannula and is put into the state of extending beyond the catheter end 5. The casting mold 6 having a convergent inner flank 7 is heated to a suitable temp. and the catheter 1 and the arbor 2 are inserted into the casting mold. The catheter 1 is then softened and molded. As a result, the front end 8 of the fin is formed at the catheter 1. The casting mold 6 and the catheter 1 are cooled and the finned catheter 1 is removed. The fin 8 is cut off by a definning jig, by which the desired venous catheter is obtd. As a result, the casting mold and arbor are not used as cutting tools and, therefore, the wear thereof is suppressed.
