Publication number: 20230019020Abstract: The present invention relates to a metal cap that has an adhesive inner surface coating film and a masking layer that can be formed in the same step thereby exhibiting excellent productivity, and a method for manufacturing the same. A coating film of a coating composition containing an adhesive component in a base resin and a masking agent is formed between the top plate portion inner surface of the metal cap shell and the olefin resin liner. The coating film has an adhesive portion that is adhesive to the olefin resin liner and a non-adhesive portion that is non-adhesive or weakly adhesive to the olefin resin liner. The adhesive portion of the coating film is formed by positioning the adhesive component of the coating composition on the coating film surface.Type: ApplicationFiled: March 10, 2021Publication date: January 19, 2023Applicant: NIPPON CLOSURES CO., LTD.Inventors: Sei NAKAGAWA, Daisuke TSUCHIMOTO

Patent number: 10894637Abstract: Provided is a plugging-type resin cap which can sufficiently seal a container and in which, upon uncapping of the container, a restraining band loosens after the pressure in the container is released without the application of an excessive force. A plugging-type resin cap (100) includes a restraining band (130), a tab (140), and engagement projections (151). The restraining band (130) has an arcuate restraining portion (131), stoppers (132), and an upwardly projecting portion (133). The stoppers (132) are formed to extend radially outward from the circumferential both ends of the restraining portion (131). The engagement projections (151) are disposed over an outer side surface of a skirt wall (120) in the vicinity of the circumferential both ends of a tab (140). The stoppers (132) and the engagement projections (151) are formed to be fittable with each other.Type: GrantFiled: July 17, 2018Date of Patent: January 19, 2021Assignee: NIPPON CLOSURES CO., LTD.Inventors: Katsumi Enomoto, Koshin Ri, Sei Nakagawa, Katsumi Hashimoto

Patent number: 9938049Abstract: A metal cap has an outer surface with a coating film including a coating composition containing thermally expandable hollow particles in a paint, the curing initiation temperature TA (° C.) of the paint, expressed as a temperature where an attenuation rate by a rigid pendulum viscoelasticity test reaches an inflection point, satisfies TA?Ta+25 Ta being the expansion initiation temperature (° C.) of the thermally expandable hollow particles, and the maximum curing temperature TB (° C.) of the paint, expressed as a temperature where the attenuation rate by the rigid pendulum viscoelasticity test reaches a peak, satisfies Tb?10?TB?Tb+10 Tb being the maximum expansion temperature (° C.) of the thermally expandable hollow particles. Because of these features, a metal cap is excellent in grip and openability even when dew condensation occurs, and is also excellent in scratch resistance, is provided with high efficiency.Type: GrantFiled: March 12, 2013Date of Patent: April 10, 2018Assignee: NIPPON CLOSURES CO., LTD.Inventor: Sei Nakagawa

Patent number: 9834690Abstract: A solvent type curable ink for ink-jet printing obtained by dissolving or dispersing, in a volatile organic solvent, polyesterpolyol having a molecular weight of not more than 8000, a hydroxyl value (KOH mg/g) of 17 to 50 and a glass transition point (Tg) of not higher than 70° C., and blocked polyisocyanate. The ink is capable of forming ink-jet-printed image on the surfaces of various kinds of formed articles without burring and maintaining close adhesion upon being heated at a low temperature for a short period of time.Type: GrantFiled: April 16, 2014Date of Patent: December 5, 2017Assignee: NIPPON CLOSURES CO., LTD.Inventors: Hiroshi Shimomura, Sei Nakagawa, Hiroaki Kikuchi, Katsumi Hashimoto

Publication number: 20150298456Abstract: The present invention is a printing method for forming an inkjet-printed image 3 on the surface of a molded article 1, characterized by: forming an ink receiving layer 5 on a portion, where the printed image 3 is to be formed, by inkjet printing in correspondence with the printed image 3 prior to formation of the printed image 3 with an inkjet using an oil-based ink. This method can form the inkjet-printed image efficiently on the surface of the molded article 1.Type: ApplicationFiled: October 29, 2013Publication date: October 22, 2015Applicant: NIPPON CLOSURES CO., LTD.Inventors: Sei NAKAGAWA, Hiroaki KIKUCHI, Katsumi HASHIMOTO
