Patent number: 9744749Abstract: A plastic container including a container body (1) made from a colored olefin resin and a decorative layer (3) laminated on the outer surface thereof. The decorative layer includes a transparent adhesive resin layer (3b), a transparent polyester resin layer (3a) which is the outer surface layer, and an intermediate gradation layer (3c) including a portion of which the thickness gradually varies in the direction of height of the container. The gradation layer is formed of a transparent polyester resin blended with a coloring agent. The thickness of the container body varies in response to a change in the thickness of the gradation layer in a manner such that the thickness of the container body portion which is the total thickness of the thickness of the container body and the thickness of the decorative layer is not varied by the presence of the gradation layer.Type: GrantFiled: February 19, 2013Date of Patent: August 29, 2017Assignee: TOYO SEIKAN GROUP HOLDINGS, LTD.Inventors: Yuuichirou Katou, Kenjiro Tanaka, Masayoshi Tanaka
