Abstract

This discharging plug comprises a vertical cylindrical housing having, in its side face, an inlet connected to the outlet of a container and the circular outlet at its lower end, a valve element having a cylindrical valve part in surface contact with the inner peripheral surface of the outlet, and an operating means installed on the upper part of the housing and opening / closing the outlet by moving the valve element in the housing. On all the periphery of either of the outer peripheral surface of the valve part and the inner peripheral surface of the outflow, a projected ring in contact with the other surface thereof facing that surface is formed, and the height of the projected ring is brought into such a range that can hold the surface contact of the outer peripheral surface of the valve part with the inner peripheral surface of the outlet. Thus, the discharging plug capable of preventing the fluid from leaking by sealing the outlet and lightly operable can be provided.

Description

technical field [0001] The present invention relates to a lead-out plug, which is detachably installed on the discharge port of a container, and allows the content liquid such as condiment and wine contained in the container to flow out in an arbitrary prescribed amount. Background technique [0002] In some cases, it is necessary to appropriately transfer seasonings, wine, etc. that have been stored in a large container in advance from the container to a small bottle or jug ​​on the table. In this case, generally, a freely openable and closable outlet plug is attached to the container, and the contents are poured out freely by operating the outlet plug. [0003] For example, there is an outlet plug in which a casing is mounted on the discharge port of a container, a valve body is movably arranged inside the casing, and the valve body is operated by operating an operating handle or the like. The body moves to open or close the outlet (see Patent Document 1, Japanese Patent ...

AI Technical Summary

Problems solved by technology

Therefore, if the gap between the valve body and the outlet is large, liquid leakage will occur at the outlet. Conversely, when the gap is small, the sliding resistance of the valve body will become large, making it difficult to open and close the outlet plug.

Furthermore, if a large force is used during operation, excessive external force will be applied to the operating rod or the threaded part of the lead-out plug, which may cause damage or reduce the durability of the lead-out plug.

[0006] By sealing between the valve body and the outlet in this way, it is difficult to reliably prevent liquid leakage, and it is difficult to easily perform opening and closing operations.
