PROBLEM TO BE SOLVED: To prevent a liquid remaining in a needle and on a needle tip from adhering to a surface of a liquid container in a process of pulling out the needle after injecting the liquid in the liquid container. SOLUTION: A first and a second elastic bodies fitted in a supply port by a housing member are sequentially disposed at the supply port from the liquid container side. At the time of pulling out the needle which injects the liquid, at least one of the position and shape of the second elastic body is changed, whereby a space to generate a negative pressure is formed between the first elastic body and the second elastic body in the liquid container.
