Patent number: 9834334Abstract: A cargo pallet made of synthetic resin includes: a top plate and a bottom plate, each plate constituted by bonded stacked synthetic-resin boards cut into a specified shape and size; and spacers bonded between the top plate and the bottom plate which are arranged in parallel and separated by the spacers. Each board is constituted by two sheets with an inner cavity layer interposed between the two sheets. In an embodiment, ribs connecting the two sheets of one board are aligned in parallel in a first direction, and ribs connecting the two sheets of another board stacked on the one board are aligned in parallel in a second direction which is perpendicular to the first direction. The spacers are elastic spacers made of synthetic resin and having spring elasticity in a height direction.Type: GrantFiled: October 10, 2016Date of Patent: December 5, 2017Assignees: G.E.S. CO., LTD., SMART STYLE JAPAN CO., LTD.Inventors: Katsutoshi Yoshifusa, Hirotaka Yoshifusa

Patent number: 9700161Abstract: A gas cushioning material preserved by easily discharging a gas from a bag part and used by filling the bag part with the gas when used again is provided. Gas cells are disposed in parallel in a gas cell row by forming heat-fusion parts in the transverse direction. A discharge valve part for discharging gas is formed at an end portion of each gas cell row. A narrowed discharge passage is formed in the discharge valve part. When the bag part is filled with a gas, the discharge valve part is bent to close the discharge passage, and in the state in which the discharge valve part is bent, a first surface fastener and a second surface fastener formed on a front surface and a rear surface of the discharge valve part are coupled to each other to maintain a closed state of the discharge passage.Type: GrantFiled: September 1, 2015Date of Patent: July 11, 2017Assignees: G.E.S.

Patent number: 8277910Abstract: A fluid container for packing a product includes a check valve for each container member. A bonding structure of check-valves to a fluid container and a production apparatus of fluid container are disclosed in detail where the check valve is capable of reliably keeping the expansion of the fluid container without any fluid leakage after inflating the fluid container. As the check-valve is bonded to only one of thermoplastic container films, both films of the check-valve are fixed to one of the container films at a plurality of seal portions, thereby preventing the reverse flow by tightly closing the check valve. The plurality of seal portions in a flow pass of the fluid disrupt the fluid flow so as to add resistance to the fluid flow.Type: GrantFiled: June 28, 2003Date of Patent: October 2, 2012Assignee: AIR-PAQ, Inc.Inventors: Yoshihiro Koyanagi, Katsutoshi Yoshifusa, Kenneth Nakagawa

Patent number: 7254932Abstract: A multi-purpose air-packing method and system enables to pack a product having an irregular shape easily at low cost. The air-packing method includes the steps of placing a product to be protected in a container box; applying a first air-packing device having a plurality of air containers to side surfaces of the product in a manner to surround the product in the container box where each of the air containers has a check valve to maintain compressed air therein independently from one another; and inflating the air-packing device by supplying compressed air to securely hold the product within the container box. Two or more consecutive air containers at one end of the first air-packing device have a cross sectional size smaller than that of other air containers.Type: GrantFiled: November 18, 2004Date of Patent: August 14, 2007Assignee: Air-Paq, Inc.Inventors: Yasuzumi Tanaka, Katsutoshi Yoshifusa

Patent number: 7204278Abstract: A check valve for use in an air-packing device has a simple structure and promotes to easily inflate all of the air cells of the air-packing device with a relatively lower pressure. The check valves can be easily attached to any locations of the air-packing device. The check valves are formed when a check valve film is attached to one of the first and second thermoplastic films. Peeling agents of predetermined pattern are applied on the check valve film which prevents heat-sealing between the first and second thermoplastic films for air tightly separating two adjacent air containers. The check valve is configured by an air flow maze portion having a zig-zag air passage and a common air duct portion which provides the air to the air flow maze portion of a current air container as well as to the air flow maze portion of a next air container.Type: GrantFiled: May 26, 2004Date of Patent: April 17, 2007Assignee: Air-Paq, Inc.Inventors: Hidetoshi Koyanagi, Yasuzumi Tanaka, Katsutoshi Yoshifusa

Patent number: 7165677Abstract: An air-packing device has an improved shock absorbing capability to protect a product in a container box. The air-packing device is configured by first and second plastic films which are bonded at predetermined portions thereby creating a plurality of air containers, each of the air containers having a plurality of series connected air cells; a plurality of check valves established at inputs of the corresponding air containers for allowing compressed air to flow only in a forward direction; and an air input commonly connected to the plurality of check valves. Through a post heat-seal treatments, predetermined edge portions are bonded, thereby creating an inner space for packing a product therein and an opening for loading the product therethrough.Type: GrantFiled: August 10, 2004Date of Patent: January 23, 2007Assignee: Air-Paq, Inc.Inventors: Yasuzumi Tanaka, Katsutoshi Yoshifusa

Publication number: 20050244527Abstract: A fluid container for packing a product includes a check valve for each container member. A bonding structure of check-valves to a fluid container and a production method and apparatus of fluid container are disclosed in detail where the check valve is capable of reliably keeping the expansion of the fluid container without any fluid leakage after inflating the fluid container. As the check-valve is bonded to only one of thermoplastic container films, both films of the check-valve are fixed to one of the container films, thereby preventing the reverse flow by tightly closing the check valve. The manufacturing apparatus includes an up-down roller controller which precisely positions the films to form the check valve. The manufacturing apparatus can produce the fluid container with high reliability by having a belt conveyor specially designed for cooling down the heat sealed films before separating from the belt conveyor without damage.Type: ApplicationFiled: June 16, 2005Publication date: November 3, 2005Inventors: Yoshihiro Koyanagi, Katsutoshi Yoshifusa, Kenneth Nakagawa
