CHEMICAL LIQUID VESSEL AND MANUFACTURE THEREOF

Japanese Patent JP3411741

B2

PROBLEM TO BE SOLVED: To facilitate the piercing operation of a needle while holding the stable strength of drape by fusion bonding the end face of the lower part of te port of a vessel to the wall surface of the upper part of a vessel body, orienting the wall surface of the upper part of the body in contact with the space inside the port into the space, and fusion bonding it to the inner wall surface and partition wall of the port.
SOLUTION: A partition wall 7 formed with a hole 7a is formed in the port 2 of the vessel. The lower part end face 4 and the inner wall surface 4a of the port 1 as well as the wall surface 5 of the upper part of a vessel body 3 in which chemical liquid is filled are heated to be melted, and the face 4 and the surface 5 are pressed to be fusion bonded. An adapter 8 is, for example, mounted in the opening 6 of the port 2, a suction device 10 is connected thereto via a tube 9, and the spaces S, S2 in the port 2 are sucked to be pressure- reduced. The upper part wall surface 5a in contact with the space S2 communicating with the space S is sucked toward the space S, oriented, and fusion bonded to the inner wall surface 5a and wall 7 in, the port 2. The partition wall 7 suppresses that the face 5a in contact with the space S2 is sucked more than necessary to be oriented.
