摘要： A hollow vessel for heat sterilization, which is superior in the transparency and in the impact resistance with scarce odor, made of a polyolefin resin having characteristic properties comprising an underwater light transmittance of 70-99% resulting from determination of light transmission at a wave length of 450 nm for a resin specimen of a thickness of 0.5 mm which has been subjected to a heat sterilization treatment with steam at a temperature of 121° C. for 20 minutes; a tensile elastic modulus of 200-700 MPa, determined according to ASTM D 638 for a resin specimen of a thickness of 0.5 mm which has been subjected to a heat sterilization treatment with steam; a haze value difference &Dgr; Haze of 1-20%, determined according to ASTM D 1330 for a resin specimen of a thickness of 0.5 mm respectively before and after a heat sterilization treatment thereof with steam; and a high-speed impact strength of 1.5-10 J, determined on an impact test at 0° C. as the total rupture energy required for rupturing a resin specimen of 0.5 mm×9 cm×9 cm which has been subjected to a heat sterilization treatment with steam, wherein the impact test is carried out by settling the specimen on a jig having a hole of 1 inch diameter for receiving an impinging weight having an impact top of a diameter of 0.5 inch and causing the weight to impinge thereonto at an impingement speed of 3 m/sec.

摘要： A container with a suspension grip can be used as an infusion solution container for drip transfusion of blood or drip infusion of a solution. A method of manufacturing the container comprises making the bottom of the preform relatively thick and providing a blow metal mold on the bottom of its cavity having the shape of a container to be produced from the preform with a resin receptacle for forming a container grip so that at least part of the thick bottom of the preform enters the resin receptacle for grip formation at the time of blow molding to form a container grip.
