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 installed on the discharge port of a container in a freely detachable manner, and can allow the condiments, wine, etc., contained in the container to flow out in any prescribed amount. Background technique [0002] Sometimes, seasonings, wine, etc., which have been placed in a container with a larger capacity in advance, are appropriately transferred from the container to a small bottle or a wine bottle on the table. At this time, generally, a discharge plug that can be opened and closed is attached to the container, and the content liquid is arbitrarily poured out by operating the discharge plug. [0003] For example, there is a lead-out plug in which the housing is mounted on the discharge port of the container, the valve body is movably installed inside the housing, and the valve is operated by operating the operating handle or the like. The body moves to open or close the outflow port (see Paten...

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.
