PROPELLING CONTAINER

摘要

A highly air-tight propelling container is provided, in which it is easy to recognize how much the content is extruded, and rotation of the rotator is prevented to avoid that the component are damaged by a wrong operation. A propelling container comprises an inner cylinder 1 having a screw rod 2 rotatably standing on a bottom part of the inner cylinder and an inner space surrounded by a side wall and serving as a content filling space M; a dispenser head 4 detachably attached to a mouth part 1c of the inner cylinder 1 and having at least one discharge hole communicated with the content filling space; an inner plate 5 threadedly engaged with the screw rod 2 and having an annular sliding band 5b elastically contacted with an inner face of the side wall of the inner cylinder 1; an annular sealing member 14 arranged in the inner plate 5 for keeping a space between the inner plate 5 and the screw rod 2 in a air tight state; a rotator 6 for rotating the screw rod 2 via the connecting rod 7 to extrude the content in the content filling space M and to discharge it from the dispenser opening of the dispenser head 4 by sliding the inner plate 5 in a air-tight state along an axis of the screw rod 2; and a lid body 21 detachably engaged with an upper part of the inner cylinder 1 to accommodate the dispenser head 4 therein. The rotator comprises a bottom wall part 6a connected to a lower end of the connecting rod 7, and a circumferential wall part 6b extending from a periphery of the bottom wall part 6a along an outer face of the inner cylinder 1 and surrounding the inner cylinder 1, thereby rotatably held by the inner cylinder 1. The rotator is provided with an elastic body 10 repeatedly contacted with and moved away from a projection of the inner cylinder 1 upon rotation of the rotator to generate a click feeling. A stopper 16 is arranged on a base part 3 of the screw rod 2 and associated with a lower part of the inner plate 5 when the inner plate 5 is positioned at the lowest end of the content filling space M, so that rotation of the rotator 6 is prevented.
