Publication number: 20200385171Abstract: A dual-structure container including an inner bag container (31) and an outer container (41) obtained by simultaneous stretch-blow molding according to a stack preform method using an inner bag container preform (1) and an outer container preform (3). On a body (33) of the inner bag container (31), contraction-control thin portions (50) are formal at a plurality of sites at intervals in the circumferential direction such that the thin portions (50) extend like strips in the axial direction.Type: ApplicationFiled: December 28, 2018Publication date: December 10, 2020Applicant: TOYO SEIKAN GROUP HOLDINGS, LTD.Inventors: Norio AKUZAWA, Kentarou ICHIKAWA, Hiroki IINO

Patent number: 10414534Abstract: A foamed and stretched plastic bottle having, in the body portion thereof, a foamed region in which foamed cells are distributed, wherein, in at least a portion of the foamed region, the lengths of the foamed cells in the axial direction of the bottle are so distributed as to gradually decrease as the positions of the foamed cells shift from the outer surface side of the body portion toward the central portion thereof and then gradually increase as their positions shift from the central portion thereof toward the inner surface side thereof. The foamed and stretched plastic bottle of the invention exhibits excellent light-shielding property.Type: GrantFiled: January 30, 2017Date of Patent: September 17, 2019Assignee: TOYO SEIKAN GROUP HOLDINGS, LTD.Inventors: Hiroki Iino, Kentarou Ichikawa, Nobuhisa Koiso, Norio Akuzawa, Tetsuro Nomura

Patent number: 10384851Abstract: A composite foamed container forming, in the body portion, thereof, a foamed region in which foamed cells are distributed, the foamed region including a first gradationally foamed region A having a gradational distribution of the foamed cells of which the length in the direction of maximum stretch gradationally decreasing from the outer surface side of the body portion toward the inner surface side thereof and a second gradationally foamed region having a gradational distribution of the foamed cells of which the length in the direction of maximum stretch gradationally decreasing from the inner surface side of the body portion toward the outer surface side thereof. The container has a large resistance against the pressure exerted on the outer surface, good liquid-dispelling property and, at the same time, has improved appearance and heat resistance.Type: GrantFiled: April 25, 2014Date of Patent: August 20, 2019Assignee: TOYO SEIKAN GROUP HOLDINGS, LTD.Inventors: Kentarou Ichikawa, Norio Akuzawa, Nobuhisa Koiso, Hiroki Iino

Patent number: 9796497Abstract: A stretched and foamed plastic formed body forming, in at least a portion thereof, a foamed region which incorporates foamed cells therein, wherein the foamed cells have a flat shape with a maximum thickness of not more than 30 ?m and an average aspect ratio of not less than 4 as viewed in cross section of the formed body perpendicular to a direction in which the formed body is stretched to a maximum degree, and a non-foamed plastic skin layer having no foamed cell distributed therein is formed on the outer surface of the foamed region. The formed body is, further, blended with a non-lustrous pigment as the coloring agent, which is different from a lustrous pigment such as flaky pigment, and exhibits a metal color over the foamed region thereof. The foamed formed body exhibiting a metal color and, specifically, a gold color or a silver color is thus provided without using any expensive lustrous pigment such as metal powder pigment or flaky pigment.Type: GrantFiled: March 4, 2013Date of Patent: October 24, 2017Assignee: TOYO SEIKAN GROUP HOLDINGS, LTD.Inventors: Norio Akuzawa, Kentarou Ichikawa, Nobuhisa Koiso, Tetsuro Nomura, Hiroki Iino

Patent number: 9694929Abstract: A foamed and stretched plastic bottle having, in the body portion thereof, a foamed region in which foamed cells are distributed, wherein, in at least a portion of the foamed region, the lengths of the foamed cells in the axial direction of the bottle are so distributed as to gradually decrease as the positions of the foamed cells shift from the outer surface side of the body portion toward the central portion thereof and then gradually increase as their positions shift from the central portion thereof toward the inner surface side thereof. The foamed and stretched plastic bottle of the invention exhibits excellent light-shielding property.Type: GrantFiled: April 23, 2013Date of Patent: July 4, 2017Assignee: TOYO SEIKAN GROUP HOLDINGS, LTD.Inventors: Hiroki Iino, Kentarou Ichikawa, Nobuhisa Koiso, Norio Akuzawa, Tetsuro Nomura

Publication number: 20150267019Abstract: A foamed stretch-formed body which has a polyolefin resin single-layer structure that is physically foamed into an expansion ratio of 1.01 to 2.0 times, wherein the surface roughness Ra (JIS-B-0601-1994) is not more than 10 ?m in the region where the cells are distributed therein. Despite of its polyolefin resin single-layer structure, the foamed stretch-formed body effectively suppresses the deterioration in the appearance or in the light-shielding capability caused by foaming.Type: ApplicationFiled: October 18, 2013Publication date: September 24, 2015Applicant: TOYO SEIKAN GROUP HOLDINGS, LTD.Inventors: Norio Akuzawa, Kentarou Ichikawa, Nobuhisa Koiso, Hiroki Iino
