Patent number: 10807780Abstract: A liquid storage container which can be securely inflated within an external container. The liquid storage container includes a bag body and an ejection outlet. The bag body includes a plurality of bellows portions formed by accordion-folding the bag body along longitudinal crease lines, and has a double-folded portion formed by folding the bag body along an upper lateral crease line and a lower lateral crease line. With reference to the bag body, the following relations are satisfied: 10%<X/H<50%, 3%<Y/H<10%, where H is the length of the bag body, x is the distance between the top periphery and the lower lateral crease line, and Y is the distance between the upper lateral crease line and the lower lateral crease line.Type: GrantFiled: January 2, 2018Date of Patent: October 20, 2020Assignee: DAI NIPPON PRINTING CO., LTD.Inventors: Ryo Harada, Hiroaki Gotou, Masato Miyake, Shota Nishimura, Noriko Kumazawa, Katsuyuki Motai

Patent number: 6861111Abstract: An additive which can improve the water resistance of a water-soluble dye with which an article has been dyed; and an ink-jet recording medium which contains the additive, is exellent in the water resistance and resolution of characters or images recorded thereon, and is suitable for multicolor recordeng. The additive is obtained by reacting a secondary amine, ammonia, an epihalohydrin, and a crosslinking agent as essential ingredients. The recording medium is obtained by causing the additive to be present on a surface and/or inner part of a base.Type: GrantFiled: February 10, 2000Date of Patent: March 1, 2005Assignee: Nippon Paper Industries Co., Ltd.Inventors: Makoto Hasegawa, Noriko Kumazawa

Publication number: 20040179075Abstract: An inkjet recording medium for plain paper wherein a coating solution having a water-soluble polymer, sizing agent and synthetic resin emulsion as main ingredients is coated or impregnation-coated on at least one surface of a base paper. The synthetic resin emulsion is an emulsion manufactured using 1.5 wt parts or less of a surfactant relative to 100 wt parts of a polymerizing monomer. In this inkjet recording medium, bleeding and feathering do not occur, so the medium is suitable also for multi-color recording.Type: ApplicationFiled: December 3, 2003Publication date: September 16, 2004Inventors: Yuji Ozawa, Akinobu Chatani, Takehiro Yoshimatsu, Noriko Kumazawa

Patent number: 6572951Abstract: A printing sheet which prevents setoff while transferring a sufficient quantity of ink and maintains necessary dot uniformity can be obtained by ensuring characteristics that the centerline average roughness showing the larger value is 1.0-3.5 &mgr;m and the ratio of centerline average obtained by dividing the larger value by the smaller value is less than 1.15 where said values are chosen at the point where the difference between the centerline average roughness in a certain direction and the centerline average roughness at right angles to said direction is maximal. Further, the abovementioned quality is further improved by appropriately ensuring that the oil absorbability is more than 4 mg/cm2 and less than 7 mg/cm2 when the contact time between the oil component having a surface tension of 27-30 mN/m at 20° C. and the printing sheet is 5 seconds and/or that the median pore diameter is 1.7-3.5 &mgr;m, in addition to the abovementioned characteristics.Type: GrantFiled: March 28, 2001Date of Patent: June 3, 2003Assignee: Nippon Paper Industries Co., Ltd.Inventors: Makoto Hasegawa, Noriko Kumazawa, Akinobu Chatani, Nobuo Nakanishi, Ryuta Ono, Hiroki Yamamoto, Teruaki Ookawa, Yasuo Yamamoto
