    摘要: Disclosed is a coated welded can having a metal-exposed face inclusive of a seam covered with a coating, wherein the coating comprises at least one organic resin coating layer and at least one metal film, and at least the portion of the organic resin coating that adheres to the metal-exposed face is comprised of a copolymer of ethylene with a carbonyl group-containing, ethylenically unsaturated monomer or a blend containing this copolymer.In this coated welded can, the adhesion of the coating, the corrosion resistance of the seam and the appearance characteristics of the seam are highly improved. Furthermore, the coating of this welded can is not damaged by such processing as flanging, beading or double-seaming or when the welded can is subjected to the retort sterilization.

    摘要: Disclosed is a process for the preparation of metal vessels, which comprises lap-bonding both the circumferential end portions of upper and lower members, each consisting of a seamless formed metal cup, through a layer of a hot adhesive interposed therebetween, wherein a high frequency induction heating coil is arranged so that the coil covers a part, smaller than the semicircle, of the circumferential portion to be formed into a seam, which circumferential portion consists of said end portions engaged with each other through the hot adhesive layer, electricity is applied to the heating coil to induce an eddy current passing through said end portions and the circumferential portion and the heating coil are rotated relatively to each other, whereby both the end portions are heated and a seam is formed by heat bonding.

    摘要: An extrusion feed device for a composite resin capable of forming a composite resin extruded material having a variety of layer configurations not necessarily symmetrical. A plurality of cylindrical flow passages (3) and (4) for feeding a molten resin, an opening/closing valve (7) capable of opening/closing a center flow passage (36) and a cylindrical flow passage (4a), and a center opening/closing valve (39) capable of opening/closing the center flow passage are provided at the upstream side end part (2a) of a discharge passage (2) for delivering the composite resin extruded material. A main resin (30a) forming an outside layer is always fed from the cylindrical flow passage (3), and the other molten resin (30b) and/or (30c) as an auxiliary resin is fed, at a proper timing, from the cylindrical flow passage (4) and the center flow passage (36) on the inside into the molten resin (30a) on the outside by controlling the opening/closing valve (7) or the center opening/closing valve (39). Thus, the composite resin mass in a variety of forms can be provided by involving, for example, multiple types of resins in the main resin layer in the state of being not involved in each other.

    摘要: The present invention provides a strong heat seal to a thermoplastic polyester container which can withstand hot water treatment such as retorting, and to a heat sealed container. A heat-sealable closure is also provided. It is composed of a laminate consisting of a heat-seal layer comprising as a main component a copolymerized polyester resin having a softening temperature of 120.degree. C. and a glass-transition temperature of 30.degree. to 85.degree. C., a metal substrate, and an epoxy-phenol resin primer layer interposed between them.Preferably, the container has a heat seal portion composed of a thermoplastic polyester having a fusion temperature in the crystalline state of at least 200.degree. C. This polyester portion is oriented and crystallized or heat-crystallized.
