Abstract

An applying material extruding container includes a movable body and a screw tube, and the movable body is moved forward by the screwing action of a screwing portion caused by the relative rotation of a filling member and a control tube in one direction. The screw tube includes a rear end tube portion, the control tube includes an internal tubular portion internally inserted into the rear end tube portion, on an outer circumferential surface of the internal tubular portion, a protrusion portion on one side that protrudes outwardly in a radial direction is provided, on an inner circumferential surface of the rear end tube portion, a protrusion on the other side that protrudes inwardly in the radial direction and that engages with the protrusion portion on one side in a rotation direction is provided and the protrusion on the other side has elasticity in the radial direction by cutouts therearound.

Dependent claims

An applying material extruding container in which a movable body and a screwing member are provided in a container including a front portion of the container and a rear portion of the container, the front portion of the container and the rear portion of the container are relatively rotated in one direction such that screwing actions of screwing portions of the movable body and the screwing member act to move the movable body forward,

wherein the screwing member includes a first tubular portion,
the rear portion of the container includes a second tubular portion internally inserted into the first tubular portion,
on an outer surface of the second tubular portion, a protrusion portion on one side that protrudes outwardly in a radial direction is provided,
on an inner surface of the first tubular portion, a protrusion portion on the other side that protrudes inwardly in the radial direction and that engages with the protrusion portion on one side in a rotation direction is provided,
at least one of the protrusion portion on one side and the protrusion portion on the other side has elasticity in the radial direction by cutouts formed therearound and
in a state where the second tubular portion has not been internally inserted into the first tubular portion, an outside diameter of a top end portion of the protrusion portion on one side is larger than an inside diameter of the inner surface of the first tubular portion whereas in a state where the second tubular portion has been internally inserted into the first tubular portion, the protrusion portion on one side is constantly in contact with the inner surface of the first tubular portion or
in the state where the second tubular portion has not been internally inserted into the first tubular portion, an inside diameter of a top end portion of the protrusion portion on the other side is smaller than an outside diameter of the outer surface of the second tubular portion whereas in the state where the second tubular portion has been internally inserted into the first tubular portion, the protrusion portion on the other side is constantly in contact with the outer surface of the second tubular portion.
