Abstract
Provided is a multi-layer container excellent in delamination resistance and gas barrier property, which can be manufactured without employing any molding method involving a special apparatus, which increases a production cost, and a complicated step. Specifically, the multi-layer container includes a laminate structure of three or more layers having at least a gas barrier layer between an innermost layer and an outermost layer, in which the gas barrier layer in a site formed of the laminate structure has a portion having a thickness 0.01 to 0.9 times as large as the maximum thickness of the gas barrier layer. Further, provided are a mold suitable for manufacturing the multi-layer container, and a manufacturing method for a multi-layer container using the mold.
