PURPOSE:To prevent liquid from leaking by providing a liquid path for discharging liquid from a device on a body, wherein a passage part having a first opening opened at an opening end and a second opening located above the opening end are included so that liquid is guided upward from the opening end at a mouth part. CONSTITUTION:Liquid 2 contained in a vessel body 3 does not flow out of a vessel 1 since pressure inside 5 the vessel body 3 functioning to a liquid level 48 and atmospheric pressure functioning to a liquid level 49 are balanced. When the vessel body 3 is pushed and deformed, pressure inside 6 the vessel body 3 functioning to the liquid level 48 becomes larger than the atmospheric pressure functioning to the liquid level 49 so that the liquid 2 passes through a path 20 over an opening 22 of a path 18 and is poured out from an outlet 24. Then, if pressing the vessel body 3 is released, the body 3 restores to its original shape due to elastic force of the body 3, reducing pressure inside 5 the vessel body 3 functioning to the liquid level 48. This allows a part of the liquid 2 remaining in the path 20 to flow back in a direction opposite to that indicated by an arrow 19 and return to the path 18, where balanced state is restored again to have the liquid level 49 placed at the path 18. |
