Patent ID: 8309189

Claim:
A multilayered liquid container, which is made of a multilayered film wherein a sealant of a resin comprising a cycloolefin resin as a main component is laminated on one side thereof and has, at a part of the container, at least one discharge port having a laminate structure at a section intersecting with a discharge path at a right angle, characterized in that: an innermost layer forming the discharge path of said discharge port is constituted of a resin comprising a cycloolefin resin as a main component, and a main part of a surface layer is constituted of a resin comprising, as a main component, polyethylene polymerized by use of a metallocene catalyst; and in a welded portion wherein the discharge port is welded with the sealant, a part of the resin comprising, as a main component, the cycloolefin resin in the innermost layer of said discharge port is exposed at the surface layer of said discharge port in the form of a band along an end edge of said multilayered film and both at least a part of the resin left as a subordinate part of the surface layer and comprising the cycloolefin resin as a main component and the resin left as a main part of the surface layer and comprising, as a main component, the polyethylene polymerized by use of the metallocene catalyst are welded with said sealant in the form of a band.
