Patent ID: 8292532

Claim:
A propelling container comprising: an inner cylinder having a screw rod 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; a dispenser head detachably attached to a mouth part of the inner cylinder and having at least one discharge hole communicated with the content filling space; an inner plate threadedly engaged with the screw rod and having an annular sliding band elastically contacted with an inner face of the side wall of the inner cylinder; an annular sealing member arranged in the inner plate for keeping an air tight state between the inner plate and the screw rod; a rotator for rotating the screw rod via a connecting rod to slide the inner plate along an axis of the screw rod with the air tight state being kept so that the content in the content filling space is lifted and discharged from a dispenser opening of the dispenser head; and a lid body detachably engaged with an upper part of the inner cylinder to accommodate the dispenser head therein, wherein the rotator comprises a bottom wall part connected to a lower end of the connecting rod, and a circumferential wall part extending from a periphery of the bottom wall part along an outer face of the inner cylinder and surrounding the inner cylinder, thereby rotatably held by the inner cylinder, and that the rotator is provided with an elastic body repeatedly contacted with and moved away from a projection of the inner cylinder upon rotation of the rotator to generate a click feeling, and that a stopper is arranged on a base part of the screw rod and associated with a lower part of the inner plate when the inner plate is positioned at the lowest end of the content filling space, so that rotation of the rotator is prevented, and wherein the elastic body is formed as a ring spring member consisting of a combination of a pair of elastic arms and grooved lugs, the elastic arms sandwiching an outer circumferential face of a base part reception ring accommodating the base part of the screw rod from two directions, leaving an allowance for displacement relative to the outer circumferential face of the base part reception ring, and the grooved lugs being integrally connected to each end of the elastic arms on both ends and biased to be abutted against projections of the inner cylinder; and that at least one end of the grooved lugs is provided with a protrusion.
