    Abstract: PROBLEM TO BE SOLVED: To provide a biodegradable resin product containing a biodegradable resin material in the material used therein in a large ratio, having sufficient barrier properties and strong enough to cause no problem from an aspect of practical use in the bonding strength of inner and outer layers, and a method and apparatus for molding the same.
    SOLUTION: The biodegradable resin product is constituted so that almost the whole of its wall part comprises the biodegradable resin material and at least two barrier layers are contained in the wall part so that a plurality of the strip like parts thereof extending in the flow direction of the resin material are arranged so as to leave an interval. Two barrier layers are formed so that the interval between the strip like parts of one barrier layer overlap the strip like parts of the other barrier layer.

    Abstract: PROBLEM TO BE SOLVED: To provide a partially multi-layered container which can be used without separating an outer layer from an inner layer, and strong in the entire container. SOLUTION: A container 200 includes a main layer 230 having the shape keeping property, and is formed of synthetic resin. A plurality of strip-like portions 240 extending in the injection direction of a molding material are provided on the outer side of the main layer 230. The main layer 230 is protruded inward of the container 200 at places with the strip-like portions 240 so that the thickness of the main layer 230 is uniform over the entire circumference of the container 200. The main layer 230 is formed of polypropylene, and the strip-like portions 240 are formed of polypropylene. The value of the melt flow rate (MFR) of the main layer 230 is equal to the value of the melt flow rate (MFR) of the strip-like portions 240, or smaller than the value of the melt flow rate (MFR) of the strip-like portions.

    Abstract: PROBLEM TO BE SOLVED: To provide a multi-layer divided vessel capable of strengthening bonding of an outer layer and an inner layer to maintain a function as a vessel, easily carrying out stripping and isolating of the outer layer and the inner layer after usage, and easily transporting the outer layer after stripped and making it into small pieces.
    SOLUTION: In the multi-layer divided vessel comprised of the outer layer having shape retention, and the inner layer capable of being stripped from the outer layer, a string part extended in the injection direction of a molding material is provided in the outer layer separably from the other part of the outer layer and the outer layer can be divided by isolating the string part from the other part.
