Description

[Detailed Description of the Invention] The present invention relates to a siphon-type liquid container.

Conventional siphon-type liquid containers have a pumping action by force-feeding pressurized air from an air pump in a lid body that is pivotally attached to the upper part of the container body to be openable and closable to a liquid container in the container body, and a pumping action for supplying the liquid container. A liquid pumping pipe that hangs down to the inner bottom of the liquid container from an inner stopper that is tightly fitted into the liquid opening, a liquid passageway in the center, a communication pipe that extends approximately horizontally from the inner stopper, and a liquid container that is outside the main body of the container. The liquid in the liquid container can be continuously poured out to the outside by the siphon effect of a series of pouring passages consisting of pouring tubes that can hang down approximately at the same level as the inner bottom. A water stop valve is provided at an appropriate position in the pouring passage to open or close the pouring passage to start or stop pouring. However, in conventional siphon-type liquid containers, the air pump can be pressed and the water stop valve can be opened at the same time, so it is difficult to keep the water stop valve open during pouring. Therefore, it is necessary to continue applying a pressing force to the pressing member of the air pump, which poses a problem of poor usability.

In view of the above-mentioned problems, the present invention aims to enable continuous dispensing even when the pressing force on the pressing member for driving the air pump is released. Therefore, in the siphon-type liquid container, a water stop valve that closes when moving up and opens when moving downward is installed in the inner stopper liquid passage, which is part of a series of dispensing passages, so that it can move up and down. At the same time, there is a space between the water stop valve and the pressing member for pressing and driving the air pump, which is rotated by a predetermined angle in conjunction with each downward movement of the pressing member to hold the lowered position and to prevent the lowered position from being held. The present invention is characterized by a structure in which an interlocking mechanism is provided, which includes a rotating body that continuously repeats holding and holding, and a pressing rod that transmits the vertical movement of the rotating body to the water stop valve.
