An elevating container includes an elliptically shaped main tube, a non-circularly shaped moveable support unit which moves upwardly or downwardly along an inner surface of a storage tube of the main tube without rotating, and a driving unit fitted to the main tube to rotate in threaded engagement to the support unit without moving upwardly or downwardly. A seal section at the lower end of the inner peripheral surface of the storage tube and a sealing cylinder at the lower end of the support unit are air-tightly fitted to each other. In addition, positioning ribs are provided at the lower end of the storage tube, and positioning notches are provided at the lower end of the moveable support unit. When the positioning ribs and the positioning notches are engaged with each other, a circumferential misalignment between the main tube and the support unit is corrected.

There is provided a liquid container capable of transferring liquids germ free in a simple manner within a short period of time and with inconsiderable solution remaining after transfer. The liquid container includes a vessel main body , a mouth portion of which is closed by an easily breakable closing member , and a hollow needle member crowned pivotably on the mouth portion of the container main body . The closing member is provided with a flat knob portion . A knob-containing portion of the hollow needle member is provided with a protrusion for joining the knob portion when the hollow needle member is pivoted.

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 to 70&deg; C. Thus formation of thermally denatured albumin can be completely restrained.
