Patent number: 10081480Abstract: An oxygen-absorbing container includes a container body having a multilayer structure constituted by an innermost layer, an outermost layer and an intermediate layer therebetween, the container body having an opening part on an upper part thereof; and a sealing member bonded to an upper end surface of the opening part of the container body to seal an opening of the opening part. The innermost layer and the intermediate layer are bent outward at an upper end of the opening part and form a flat part and a surface of the flat part forms the upper end surface of the opening part. When the sealing member is unsealed, part of the innermost layer on the upper end surface of the opening part is configured to be peeled off so as to leave an unsealed mark.Type: GrantFiled: March 12, 2015Date of Patent: September 25, 2018Assignee: MITSUBISHI GAS CHEMICAL COMPANY, INC.Inventors: Kenichi Niimi, Kiyonori Michiba, Takashi Kubo, Kazuyuki Minato, Yoshiki Itou, Takayoshi Itoh, Jungo Taguchi, Akihiro Masuda, Tatsuo Iwai

Patent number: 9334377Abstract: There is provided a process for producing a resin composition in a safe and cost-effective manner, the resin composition being a dispersion of active particles reactive with oxygen in a thermoplastic resin. The process is one for producing a resin composition containing at least a thermoplastic resin and active particles that have been dispersed in the thermoplastic resin and are reactive with oxygen in an atmosphere, the process comprising the steps of: protecting the active particles with a dispersion medium to prevent oxygen in the atmosphere from contacting with the active particles; removing the dispersion medium while melt-kneading the thermoplastic resin and the active particles protected with the dispersion medium to replace the dispersion medium with the thermoplastic resin; and cooling and solidifying the thermoplastic resin with the active particles dispersed therein.Type: GrantFiled: July 19, 2013Date of Patent: May 10, 2016Assignee: MITSUBISHI GAS CHEMICAL COMPANY, INC.Inventors: Akihiro Masuda, Yoshiki Itou, Kiyonori Michiba
