Patent number: 10858165Abstract: A double-walled container includes an outer layer body and an inner layer body. A single adhesive strip is disposed between the outer layer body and the inner layer body in a manner such that the adhesive strip extends along a center axis. The outer layer body is provided with a single ambient air introduction hole. The outer layer body includes an inner surface, which is configured by a separation surface and a pseudo-adhesive surface. The separation surface faces the ambient air introduction hole and is separated from an outer surface of the inner layer body, and the pseudo-adhesive surface faces the separation surface and is separably adhered to the outer surface of the inner layer body.Type: GrantFiled: July 25, 2019Date of Patent: December 8, 2020Assignee: YOSHINO KOGYOSHO CO., LTD.Inventor: Shintaro Kutsuzawa
