摘要： A multilayered liquid container having a discharge port welded under specified conditions to a sealant, which is constituted of a resin comprising a cycloolefin resin as a main component. The discharge port is composed of: an innermost layer constituted of a resin comprising a cycloolefin as a main component; and a surface layer whose main part is constituted of a resin comprising a specific type of polyethylene as a main component. According to the present invention, there can be provided a multilayered liquid container, which can prevent an effective component of a content fluid from being adsorbed onto or penetrating through not only the container body, but also the resin constituting the discharge port, and enables high temperature sterilization treatment, coupled with the discharge port having high welded strength and drop strength.
