  • Patent number: 10508214
    Abstract: The present invention relates to a polyester coating composition used for forming a coating film of a coated metal plate, a metal container, a metal closure, etc. The coating composition has a crosslinking agent and a curing catalyst incorporated into a mixed polyester resin comprising a mixture of a polyester resin (A) having an acid value of 2 to 50 mg KOH/g and a glass transition temperature (Tg) of 35 to 100° C. and a polyester resin (B) having an acid value of 0 to 50 mg KOH/g and a glass transition temperature (Tg) of ?20 to 25° C. Thus, a coating composition excellent in resistance to embrittlement over time, corrosion resistance, scrape resistance, retort resistance, and blocking resistance can be provided.

  • Patent number: 10213991
    Abstract: A multilayered container includes at least a polyolefin inner layer; an adhesive layer; a gas-barrier layer; an oxygen-absorbing layer; a gas-barrier layer; an adhesive layer; a polyolefin outer layer, and having at least a body portion and a bottom portion, wherein the gas-barrier layers include an ethylene-vinyl alcohol copolymer, the oxygen-absorbing layer includes an oxygen-absorbing resin composition that contains the ethylene-vinyl alcohol copolymer and an oxidizing organic component, an adsorbing agent is contained on the side inside of said gas-barrier layer, the thickness of the multilayered container at the thinnest portion is not more than 430 ?m, and the amount of oxygen absorbed after the heat-sterilization is not less than 23 cc per gram of the oxygen-absorbing resin composition. Despite of this decreased thickness, the multilayered container maintains excellent oxygen-barrier property and property for retaining flavor of the content even when it is subjected to the retort sterilization.

  • Patent number: 9736891
    Abstract: An induction heating container (1) in which an induction heat generator (3) is attached to the inside of a container main body (2) made of a non-conductive material so as to enable cooking by heating by an electromagnetic cooker. The induction heat generator (3) includes: a laminated body involving a conductor layer (4) that generates heat by induction of eddy current by high-frequency magnetic field and a heat-seal layer (5) that imparts heat-sealing properties to the container main body, and an eddy current control part (6) obtained by cutting the conductor layer (4) along the circumferential direction.
