Containers for pushing out applying material

Abstract

Containers for pushing out applying material are disclosed, which makes the fabrication easy and fully ensures the pushing strength of the applying material. When a main body tube and an operation tube in the container are relatively rotated toward a first direction, a moveable screw tube advances for a predetermined amount, and when relative rotation is further carried out toward the first direction, a screwing part exerts screw function to urge a moving body forward. In the container, a front end part of a female thread of the screwing part in the moveable screw tube is radially outwardly expandable via a slit, so that the so-called pulling perforce can be performed in the case that the female thread is formed by using a core pin for instance. Moreover, when the moveable screw tube advances for a predetermined amount through relative rotation toward the first direction, the outer diameter of the front end part is restricted and expansion thereof is hence prevented, so that, when relative rotation is further carried out toward the first direction and the screwing part exerts screw function to urge the moving body forward, it is possible to suppress expansion of the front end part and hence expansion of the female thread of the screwing part. Accordingly, the screwing part reliably exerts screw function when the moving body advances.

Description

technical field [0001] The present invention relates to a coating material ejection container for ejecting coating material for use. Background technique [0002] As a conventional coating material ejecting container, a coating material ejecting container including a moving body screwed to a moving threaded barrel via a screwing portion inside the container is known (for example, refer to Patent Document 1). In this coating material ejecting container, when the container front and the container rear are relatively rotated in one direction, the moving body advances under the screwing action of the screwing portion, so that the coating material is pushed out from the opening of the container front. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2008-43590 [0004] Here, in the above-mentioned coating material ejection container, a slit is formed at the end of the moving screw cylinder constituting the female thread of the screwing portion so as to expand radially o...

Problems solved by technology

[0005] However, in the above-mentioned coating material ejection container, since the slit is formed at the end of the moving screw cylinder constituting the female screw as described above, when the moving body is advanced by the screwing action of the screwing part, depending on the situation, Depending on the difference, sometimes the screwing effect of the screwing part is not fully exerted, so that the push-out strength of the coating material is not sufficiently obtained.
