Patent number: 11975885Abstract: A method for producing a delamination container, wherein the delamination container includes an outer layer body constituting an outer shell of the container and an inner layer body that is laminated on an inner side of the outer layer body in a manner such that the inner layer body is peelable from the outer layer body. The inner layer body comprises an ethylene-vinyl alcohol copolymer resin, and is deformable to undergo volume reduction and the outer layer body includes an outer layer body's inside sub-layer that is located adjacent to the inner layer body and that is made of a polypropylene resin and an outer layer body's outside sub-layer that is located on an outer side of the container relative to the outer layer body's inside sub-layer and that is made of a polyethylene resin. The method comprises a process to form the delamination container by co-extruding resins in a molted state to prepare a cylindrical laminated parison and blow molding the prepared laminated parison.Type: GrantFiled: April 3, 2020Date of Patent: May 7, 2024Assignee: YOSHINO KOGYOSHO CO., LTD.Inventors: Mitsuo Furusawa, Yoshiaki Gondo, Kazuhiko Akiyoshi

Patent number: 9067709Abstract: The technical problems of this invention are to overcome a limitation in the aspect of the shape of conventional synthetic resin double containers comprising an inner container and an outer container and to solve a problem of additional steps required to assemble the outer and inner containers. A principle means taken to solve these problems comprises a double container made by a direct blow molding process wherein a space is formed between the outer layer and the inner layer made of synthetic resins that are mutually non-adherent, thus allowing both layers to be left in a detached state due to a difference in mold shrinkage factors between the two layers during the direct blow molding step.Type: GrantFiled: June 19, 2008Date of Patent: June 30, 2015Assignee: YOSHINO KOGYOSHO CO., LTD.Inventor: Mitsuo Furusawa

Patent number: 9061823Abstract: A two-fluid dispenser capable of reducing odor, even when one of two fluids dispensed in foam has pungent odor. The dispenser includes: a first and a second dispenser container each including an upper surface from which a stem protrudes and is configured to dispense a fluid therein in foam in response to the stem depressed; and a dispenser tool fixedly fitted over the containers. The dispenser tool includes a dispenser head communicating with the containers and including a nozzle, so that when the dispenser head is depressed, the fluids are dispensed from the containers through the nozzle. The dispenser head includes a fluid guide mechanism to guide the fluids from the containers to be dispensed in foam through the nozzle such that the fluids have a layered pattern in which a first fluid layer is at least partly covered by a second fluid layer.Type: GrantFiled: August 26, 2011Date of Patent: June 23, 2015Assignees: HOYU CO., LTD., YOSHINO KOGYOSHO CO., LTD.Inventors: Hiroki Sugimoto, Mitsuo Furusawa
