Abstract: 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.

Abstract: An advancing container constructed from an elliptically tubular body tube (1), a tubular tray body (21) having a non-circular shaped lateral cross-section and non-rotatably moves up and down in a containing tube section (2) in the body tube (1), and a driving body (11) mounted to the body tube (1) so as to be able to rotate and not to be able to move up and down and screw-fitted to the tray body (21). A seal section (3) at the lower end of the inner peripheral surface of the containing tube section (2) and a seal tube section (24) at the lower end of the tray body (21) are adapted to be able to be tightly fitted to each other. A positioning rib (4) is provided at the lower end of the containing tube section (2), and a positioning cutout (25) is provided at the lower end of the tray body (21). When the positioning rib (4) and the positioning cutout (25) are engaged with each other, circumferential displacements of the body tube (1) and the tray body (21) are corrected.

Abstract: 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 1, a mouth portion 11 of which is closed by an easily breakable closing member 12, and a hollow needle member 2 crowned pivotably on the mouth portion 11 of the container main body 1. The closing member 12 is provided with a flat knob portion 121. A knob-containing portion 22 of the hollow needle member 2 is provided with a protrusion 24 for joining the knob portion 121 when the hollow needle member 2 is pivoted.
