[Problems to be solved by the invention]
In the container, the lower part of the suction pipe is bent downward and the lower end thereof is positioned on the outer peripheral part of the bottom wall of the container body. Although the container body is tilted so that the outer peripheral portion of the container body bottom wall is positioned downward, the liquid in the container is collected, and the liquid is ejected without leaving the liquid by performing the pump operation in the container body tilted state. For example, if the container body is opaque, the position of the lower end of the suction pipe to bend is unknown, and therefore it is difficult to tilt the container body so that the bottom portion of the container body where the lower end of the suction pipe is located is positioned downward.
[0005]
The present invention provides the container body so that the nozzle of the push-down head is always positioned in the direction in which the lower end of the suction pipe is located when viewed from above the container body, and the container body bottom wall portion on the side from which the nozzle protrudes is downward. If tilted, the liquid can be collected at the lower end portion of the suction pipe, so that the liquid in the container can be ejected with almost no residue.
