Discharge device and container with the same

Abstract

The invention provides a discharge device capable of strongly maintaining an unused state and a container with the same, specifically, a discharge device composed of an inner cover (A) screwed down to a neck portion 22 of the container, a pump (B) mounted on the inner cover, a pushing-down head (C) mounted at the top of the pump, a retainer ring (D) preventing the pushing-down head from being pressed downwards, and an outer cover (E) sheathing the inner cover and the retainer ring, wherein the outer cover (E) is composed of a main body portion sheathing the inner cover and a shield portion sheathing the retainer ring; a ratchet mechanism is arranged between the inner cover (A) and the outer cover (E) to take effect in a direction where the inner cover is screwed on the container; and the ratchet mechanism is set in such a manner that the rotation thereof in a reverse direction is in an idle state in a state where the inner cover is completely screwed on the container; the shield portion of the outer cover (E) is disconnectable so that a structure in which the retainer ring (D) is detachable after the shield portion is disconnected is formed.

Description

technical field [0001] The present invention relates to a discharger for discharging liquid contained in a container by a pump, and a container with the discharger. Background technique [0002] In Patent Document 1 (Japanese Unexamined Patent Publication No. 2009-131807 ) and the like, various types of ejectors having a structure in which a liquid contained in a container is ejected from a ejection hole of a lower head by the action of a pump have been proposed. And also proposed following structure, promptly under unused condition, can not press downwardly the structure that presses down, prevents that under unused condition, spits liquid from downpressed head, for example has patent document 2 (No. 2001-180774 of Japanese Patent Laid-Open Bulletin), etc. In this conventional example, in the unused state, after the liquid in the container is taken out by either removing the cap (stop ring) or pulling out the lower plunger, etc., no special consideration is given to make i...

AI Technical Summary

Problems solved by technology

In this conventional example, in the unused state, after the liquid in the container is taken out by either removing the cap (stop ring) or pulling out the lower plunger, etc., no special consideration is given to make it impossible to return to the unused state, etc.

[0003] The retaining ring for a container with a pump disclosed in Patent Document 2 (Japanese Unexamined Patent Application Publication No. 2001-180774) has a metal mouth portion which is provided with a container body and is airtightly mounted on the container body. The cover part of the pump mechanism that discharges the liquid content contained in the main body, and the container with the pump installed in the pump part on the upper end of the cover part are detachably fitted on the cover to prohibit the operation of the pump mechanism. In the state of use, the stop ring can be reinstalled after pressing down on the pump to discharge the liquid. Therefore, there is a problem that the liquid in the container may be sucked out when not in use.
