Coating material pushed out of container

Abstract

A coating material ejection container is easy to manufacture and sufficiently ensures the ejection strength of the coating material. In the container, when the main cylinder and the operation cylinder are relatively rotated in one direction, the moving threaded cylinder advances by a certain amount, and when further relatively rotated in one direction, the screwing part exerts a screwing action to advance the moving body. In this container, the front end of the female thread provided with the threaded part in the moving thread cylinder can expand radially outward through the slit, so when the female thread is formed with a plastic hole plug, so-called hard drawing can be performed. . Furthermore, when the moving threaded cylinder advances by a certain amount by relative rotation in one direction, the outer diameter of the front end portion is restricted so that expansion is prevented, so when it is further rotated relative to one direction, the screwing portion exerts a screwing action to advance the moving body , it is possible to suppress the expansion of the internal diameter of the female thread of the screwing portion due to the expansion of the front end portion. Thereby, when the moving body advances, the screwing action of the screwing portion can be reliably exhibited.

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.
