Abstract
A pouring mouth member for a container includes an intermediate resin layer having barrier property and a fold-back portion is formed on at least one end portion of the intermediate resin layer having barrier property. Further, due to an inner layer resin and/or an outer layer resin provided to an outer periphery of this fold-back portion, the exposure of the resin having barrier property can be surely prevented and, at the same time, a cut edge of the intermediate resin layer having barrier property is effectively sealed between the inner and outer layer resins since the cut edge is also in a fold-back state.
