A container assembly including a pouch, spout and closure is provided. The closure includes a tamper-evident band comprising two or more wall sections. Adjacent wall sections of the tamper band may be connected to one another with frangible connectors configured to break upon twist-off of the closure from the spout. The closure also includes one or more support walls supported between an outer wall and central wall of the closure. The closure further includes one or more hinges attaching the ends of the wall sections of the tamper band to the lower ends of the support walls. The hinges are configured to increase the resistance required to break or otherwise distort the frangible connections of the tamper-evident band, so as to prevent or lower the risk of accidental or inadvertent breakage of the tamper-evident band prior to twist-off of the closure from the spout.
