Abstract
To provide a plastic vessel containing an albumin preparation which completely restrains formation of thermally denatured albumin, a plastic molded member in a cylindrical shape is extruded in a molten state into opened dies, one end of which is closed in the dies, and a vessel is molded by blowing a compressed gas into the molded member in the dies or by bringing inner portions of the dies into a vacuum state. While the vessel is still disposed in the dies, an albumin preparation is introduced from an opening portion into an inner portion of the vessel and, therefore, the albumin preparation can be filled into the vessel in a sterilized state without being brought into contact with the atmosphere. Then, an opening portion of the vessel filled with the albumin preparation is hermetically sealed at an internal temperature of the opening portion of about 40.degree. to 70.degree. C. Thus formation of thermally denatured albumin can be completely restrained. A METHOD FOR PRODUCING A PLASTIC VESSEL CONTAINING AN ALBUMIN PREPARATION
