Patent number: 10329076Abstract: A double-walled container including: an outer layer body; an inner layer body, which is provided in a pinched-off portion and which passes through the outer layer body. The pinched-off portion is formed in a bottom due to pinch-off using a splittable mold in blow molding. The bottom is provided, on an inner side in a radial direction of an outer edge portion thereof, which serves as a ground-contacting surface, with a substantially cross-shaped recess, which is concave toward a mouth. The recess is configured by a first-direction recess portion, which extends along an extending direction of the slit, and a second-direction recess portion, which intersects with the first-direction recess portion. The slit is provided in a region in which the first-direction recess portion and the second-direction recess portion intersect with each other.Type: GrantFiled: January 20, 2016Date of Patent: June 25, 2019Assignee: YOSHINO KOGYOSHO CO., LTD.Inventors: Shuichi Kitora, Tomoaki Kurihara, Keisuke Miyairi

Patent number: 9238527Abstract: A dispensing container provides that after discharging content, the content which has not been returned to an internal container is prevented from leaking out of a discharge port. The dispensing container has an internal container which contains content and an external container in which the internal container is attached. The external container is provided with a suction port for sucking external air in between the internal container and the external container. A discharge cap is attached to a spout and is provided with a discharge port for discharging the content. The discharge cap includes an inside plug which closes the spout and a cylindrical body covering the inside plug and being provided with the discharge port. The inside plug is provided with a communication port. A valve that is slidable along an axial direction of the communication port is provided to open and close the communication port.Type: GrantFiled: June 5, 2012Date of Patent: January 19, 2016Assignees: YOSHINO KOGYOSHO CO., LTD., KIKKOMAN CORPORATIONInventors: Yoshiyuki Kakuta, Satoshi Sakamoto, Keisuke Miyairi, Denmi Kuwagaki, Masashi Fukumoto
