摘要： PURPOSE: To obtain a printed seamless can superior in corrosion resistance by performing a ultraviolet-curing printing on the external side wall surface of a metallic cup-shaped container with an organic coating on inner surface and thereby minimizing the damage caused by working on the inside organic coating. CONSTITUTION: A formed and trimmed metallic cup 3 with an organic coating is fed to a turret 1 for printing by means of a feeding mechanism 7. Then, an ultraviolet-curing ink layer is applied on the external side wall surface by means of a printing unit 4 and, on top of this ink layer, an ultraviolet-curing finishing varnish layer is applied in a wet-on-wet relation by means of a unit 5 for applying finishing varnish. The printed cup 3a is transferred to a hardening turret 2, irradiated with an ultraviolet light source 6 provided in the periphery and applied with the ultraviolet curing for the printed ink layer and the finishing varnish layer. The cup 3b with the printing hardened is discharged outside the device by means of a discharging mechanism 8. Then, the upper end of the opening of the printed metallic cup-shaped container is heat-treated after neck-in working and flange working.

摘要： PROBLEM TO BE SOLVED: To prevent a coating film from a damage such as peeling by applying a coating material containing resin particulates in a specified wt.% so that a part of the particulates may be embedded in the coating film and remainder may be projected from a surface of the coating film, and curing the coating material by ultraviolet ray. SOLUTION: 2-10wt.% Resin particulates are incorporated in the ultraviolet curing type coating material. Then a part of the particulates is embedded in the coating film and remainder is allowed to protrude from the surface of the coating film and cured by the ultraviolet ray. An average grain size of the resin particulates is kept in 5-15μm, and a smooth part of the cured coating film is kept in 0.5-1 time thickness of the average grain size of the resin particulates. For example, a resin other than resin particulates, reactive diluent, oligomer and monomer are blended and dissolved. Moreover, lubricants, an initiator, sensitizer, titanium oxide and 2-10wt.% resin particulates are added to produce the ultraviolet curing type coating material. The coating film having a coefficient of dynamic friction of about 0.10 is obtained in the case when the coating material is applied and cured by ultraviolet ray and the peeling is prevented and a resistance to scuffing is improved.

摘要： PROBLEM TO BE SOLVED: To make it possible to form printed layers satisfying all of workability, heat resistance, wear resistance, brightness, etc., by curing specific ink and coating materials by irradiation with UV rays, then executing various kinds of the moldings necessary for maintaining designs and strength, subjecting molded cans to a short time of heat treatment to thermally cure the UV curing films. SOLUTION: The ink and coating materials having a UV curing property and thermosetting property in combination or the ink and coating materials which has the UV curing property and is imparted with the thermosetting property by irradiation with UV rays is selectively used as the ink and coating material. Various kinds of the moldings, such as neck forming or bead forming of the printed cans, necessary for maintaining the designs and strength are then executed, but before such molding, the curing of the ink and the coating materials by the irradiation with the UV rays, is executed and, after such molding, the molded cans are subjected to the short time of the heat treatment to thermally cure the UV curing films. Then, the printed layers have the excellent heat resistance, wear resistance, etc., and withstand the retort sterilization and the collision and rubbing of the cans against each other.

摘要： PURPOSE: To increase the anticorrosition property and external appearance, by providing an ultraviolet ray setting coating layer mixed with titanium oxide with a specified thickness on the external face film layer at the side wall of a metallic material and setting the total amount of titanium oxide per unit area of the side wall of external face at least in a specified value. CONSTITUTION: In a thinned seamless can 1, the metallic base material 11 is coated with a thermoplastic film at both inside and outside and an ultraviolet ray setting coating layer 16 mixed with titanium oxide having 3-20 micron millimeter in thickness is applied on the external face side film layer of the side wall 3. And the total amount of titanium oxide per unit area of the external face side wall is at least 0.5mg/cm . When the thickness of ultraviolet ray setting coating layer 16 mixed with titanium oxide is finer than 3μm, a sufficient whiteness degree cant not be obtained and also the hiding power is not enough. On the other hand, when the thickness is larger than 20μm, the coating layer can not follow at the neck-in process and hence, the coating layer is broken. Since the coating layer has been hardened by ultraviolet ray, it is lustrous and excellent in score-resistance and hence, the external appearance characteristics are increased.

摘要： PROBLEM TO BE SOLVED: To improve the impact resistance and the corrosion resistance after a formed can for which a printing and a secondary process have been applied by a method wherein a plurality of oriented crystalization states being shown by specified endothermic peaks in a differential thermal analysis, are imparted to a polyester layer on the internal surface of the can, and a spontaneous stretching property is imparted to a polyester layer straight under the flange part. SOLUTION: A laminate plate 1 wherein at least on the internal surface of a metal plate 2, a biaxially oriented polyester film 3 is laminated by a condition to remain the biaxial orientation, is draw-iron-molded, and is formed into a can body wherein the polyester layer 3 is uniaxially oriented, and a heat treatment is performed by a temperature which is -60 to -5 deg.C of the melting point of the polyester. Then, a printing is applied on the external surface of the can body with an ultra-violet ray hardening type ink, and the ink is hardened by irradiating ultra-voilet rays. Then, the printed can body is secondarily molded, and a post-heat treatment is performed by a temperature which is +100 to 150 deg.C of the glass transition point of the polyester. By this method, three kinds of oriented-crystalization states corresponding with specified three endothermic peaks in a differential thermal analysis, and internally distorted state are realized on the polyester layer 3.
