<P>PROBLEM TO BE SOLVED: To provide a multilayered plastic vessel maintaining excellent slippage to a viscous content such as ketchup or the like stably for a long period of time. <P>SOLUTION: In the multilayered plastic vessel having a lubricant-containing olefin-based resin layer as the innermost layer, the X-ray profile (2θ/θ) obtained by conducting an X-ray diffraction measurement by a reflection method to the inner surface of the vessel has a peak coming from a multi-molecular layer structure of the lubricant bled to the inner surface of the vessel, and the half width of the peak showing the maximum strength among the peaks is in the range from 0.05 to 0.2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
