There was a problem in that it was difficult to perform liquid injection operations in this posture.

Therefore, it is possible to install a lever-like air pump operating member on the outer surface of the container body to lower the operating position of the air pump, but in that case, the position and shape of the air pump operating member must be carefully considered. At times, there is a risk that the container body may become unstable.

(Means for Solving the Problems) In the present invention, as a means for solving the above problems, an external pouring passage that forms a part of the liquid injection passage for pouring the liquid inside the container body to the outside is provided. On both sides of the pipe cover that covers the pipe, an external operating member for pressing and driving the air pump disposed inside the container body, which is approximately U-shaped so as to straddle the pipe cover, is installed. Both ends of the dispensing operation lever are rotatably supported, and an operating section located in the center of the dispensing operation lever is positioned at the center of the outer surface of the pipe cover, and the dispensing operation lever is mounted on the top of the pipe cover. A recessed positioning and accommodating portion is provided for positioning and storing the operating portion of the operating lever, and in the stored state, the operating portion is substantially flush with the outer surface of the pipe cover.

(Function) In the present invention, the following effects can be obtained by the above means.

That is, the air pump operation position is at a low position, and the operation part is located at the center of the pipe cover, so that the air pump operation can be performed in a stable state. In addition, the operation part of the pouring operation lever is
When the pipe cover is stored in the positioning storage section at the top of the pipe cover, it is supposed to be flush with the outer surface of the pipe cover, so inadvertent external force is applied to the operation part of the pouring operation lever in the positioning and storage state. is prevented.
