Embodiment 1
[0083] like figure 1 As shown in , a gate 2 is provided in the center of the circumferential surface of the cylindrical container 1, and a styrene-butadiene copolymer resin is injection-molded by a mold to obtain a total length of 280 mm, an outer diameter (tube part) of 40 mm, and a wall thickness of 2 mm. In the cylindrical container for body fluid treatment, three air exhaust pipes are installed at approximately equal intervals as the gas discharge part on the outer surface side of the mold that abuts on the weld line 3 that appears on the cylindrical container 1. pin 6.
[0084] As a result of the impact test A, it was confirmed that the impact strength of the part not on the weld line was 20kg·cm / cm, while the impact strength on the weld line was 12kg·cm / cm, maintaining 60% of the impact resistance strength. The results are shown in Table 1.
Embodiment 2
[0086] like figure 2 As shown in , two gates 2 are provided near both ends of the circumferential surface of the cylindrical container 1, and a styrene-butadiene copolymer resin is injection-molded using a mold to obtain a total length of 280mm, an outer diameter (tube part) of 40mm, In the cylindrical container for body fluid treatment with a wall thickness of 2mm, in the mold, the outer surface side of the mold that abuts on the welded line 3 that appears on the cylindrical container 1 is mounted on the circumferential surface facing each other. The root is the exhaust needle 6 as the gas discharge part.
[0087] As a result of the impact test A, it was confirmed that the impact resistance of the part not on the weld line was 20kg·cm / cm, while the impact resistance on the weld line was 11kg·cm / cm, maintaining 55% of the impact resistance strength. The results are shown in Table 1.
Embodiment 3
[0089] like image 3 As shown in , except that the structure of the mold for obtaining the cylindrical container 1 with threads applied to both ends was used, the same mold as in Example 2 was used to install the gate and the exhaust needle, and the acrylonitrile resin was injection-molded to obtain a total length of 280 mm. , A cylindrical container for body fluid treatment with an outer diameter (cylindrical portion) of 40 mm and a wall thickness of 2 mm.
[0090] As a result of the impact test A, it was confirmed that the impact resistance of the part not on the weld line was 16kg·cm / cm, while the impact resistance on the weld line was 10kg·cm / cm, maintaining 63% of the impact resistance strength. The results are shown in Table 1.
