摘要： A transparent multi-layer container comprising a co-extrudate of an oxygen-barrier resin layer and an orienting resin layer which is monoaxially or biaxially oriented is disclosed. An adhesive resin layer is preferably interposed between the oxygen-barrier layer and the orienting resin layer, and this co-extrudate is drawn and molded at a specific temperature determined relatively to the melting points and softening points of the respective resins. This container is excellent in the combination of transparency, rigidity, mechanical strength, gas-barrier property and interlaminar peel strength.

摘要： In a multi-layer blow molded container having a joint portion at least in the bottom portion thereof, barrier characteristics to gases such as oxygen and water vapor and liquids such as water, solvents, aqueous ammonia and salt water and interlaminar strength characteristics such as interlaminar adhesion strength, peel strength and impact strength in the content-filled state can be highly improved by blow molding a parison of a laminate structure of two or more polymer layers in which the polymer composition is different with respect to the thickness direction of the container wall but substantially identical with respect to the plane direction and each of the polymer layers is continuous with respect to the plane direction, in such a manner that a tapered projection protruding outwardly in the thickness direction of the container wall is formed in the joint portion so that each of the polymer layers is substantially continuous in this joint portion. This improved container can easily be prepared according to the customary blow molding technique by using a pair of split molds having such a configuration that a tapered concave groove is formed in the section pinching off the parison when the molds are registered with each other.

摘要： The present invention is based on the finding that when a multi-layer blow-formed body is heat-treated, cooled and taken out, an intermediate layer of a gas-barrier resin in the multi-layer blow-formed body acts as a heat-insulating layer and if the blow-formed body is cooled from the interior by a cooling fluid, a shape-retaining property necessary for taking out the blow-formed body from the mold can be promptly obtained. A biaxially drawn polyester vessel excellent in the resistance to thermal contraction and gas-barrier properties can be prepared at a high manufacturing speed with a reduced number of steps by preheating or temeprature-adjusting a multi-layer preform comprising inner and outer layers of a polyester composed mainly of ethylene terephthalate units and at least one intermediate layer composed of a gas-barrier resin to a temperature suitable for drawing, carrying out the biaxial draw-blow forming of the preform and the heat treatment of the blow-formed body in a mold maintained at a heat-setting temperature, changing over a compressed fluid for the blow-forming to a fluid for internal cooling, cooling the blow-formed body to a temperature at which deformation is not caused when the blow-formed body is taken out from the mold, while contacting the blow-formed body with the surface of the mold cavity, and taking out the formed body from the mold.
