Publication number: 20230026514Abstract: The present invention provides a laminated sheet for manufacturing a packaging container. The laminated sheet comprises a pair of plastic sheets, a barrier sheet, a barrier region, an easily peelable region, and a fixing region. The barrier sheet has flexibility and is disposed between the pair of plastic sheets. The barrier region is formed by overlapping the pair of plastic sheets and the barrier sheet with each other. The easily peelable region is provided in the barrier region. The fixing region is located in a circumference of the easily peelable region, in which the pair of plastic sheets are fixed to each other directly and/or via the barrier sheet. A peel strength between the pair of plastic sheets and the barrier sheet in the easily peelable region is smaller than a direct peel strength between the pair of plastic sheets and/or a peel strength between the pair of plastic sheets via the barrier sheet in the fixing region.Type: ApplicationFiled: December 24, 2019Publication date: January 26, 2023Applicant: KAO CORPORATIONInventors: Yoshinori INAGAWA, Akira NONOMURA, Masayasu SATO

Patent number: 6797120Abstract: A method for producing a pulp molded article is disclosed. The method comprises the steps of forming and drying a pulp molded precursor (15). The drying step includes a first step and a second step. In the first step, the precursor (15) is set in a cavity of a heating mold, and is hot-pressed. The cavity has a configuration in conformity to the contour of the pulp molded article to be produced. In the second step, the hot-pressed precursor (15) is taken out from the heating mold and is heat-dried in a drying furnace.Type: GrantFiled: April 10, 2003Date of Patent: September 28, 2004Assignee: Kao CorporationInventor: Akira Nonomura
