摘要：
The present invention relates to a mold for a multi-layer container. The mold includes a cold-half portion containing a cavity, and a hot-half portion containing a first resin flow path for connecting an interior of a first injection cylinder to the cavity, a second resin flow path for connecting an interior of a second injection cylinder to the cavity, and a junction portion of the first resin flow path and the second resin flow path. The junction portion in the hot-half portion is positioned upstream of a gate portion opened to the cavity included in the cold-half portion, the second resin flow path contains an inhibitor for partially inhibiting a resin flow.
