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. When the tray body is retracted, the body tube (1) and the tray body (21) are always aligned in position with each other.

Claims8

Dependent claims

The twistable container of this invention for elevating a solid stick mainly comprises:

a main tube having a seal portion at a lower end of an inner peripheral wall of a straight cylindrical storage tube in a cross-sectional shape which is not a circle or a perfect circle,
a driving unit fitted to a lower end of this main tube in a manner unable to go up or down but able to rotate, said driving unit having a central shaft disposed upright at the center of the main tube,
a movable support unit fitted in the storage tube in a manner unable to rotate but able to go up or down slidably, the movable support unit having a screw engagement with a screw-threaded portion notched on the central shaft standing upright on a central axis and having also a sealing cylinder disposed at a lower end so as to have tight contact with the seal portion of the storage tube,
wherein a storage space, in which to store the solid stick, is formed by the storage tube, the movable support unit, and the central shaft, and
wherein positioning ribs disposed at the lower end of the storage tube of the main tube are brought to an engagement with positioning notches cut in a lower end portion of the movable support unit so as to correct forcibly any circumferential “misalignment” of the movable support unit relative to the main tube.
