  • Patent number: 9744749
    Abstract: A plastic container including a container body (1) made from a colored olefin resin and a decorative layer (3) laminated on the outer surface thereof. The decorative layer includes a transparent adhesive resin layer (3b), a transparent polyester resin layer (3a) which is the outer surface layer, and an intermediate gradation layer (3c) including a portion of which the thickness gradually varies in the direction of height of the container. The gradation layer is formed of a transparent polyester resin blended with a coloring agent. The thickness of the container body varies in response to a change in the thickness of the gradation layer in a manner such that the thickness of the container body portion which is the total thickness of the thickness of the container body and the thickness of the decorative layer is not varied by the presence of the gradation layer.

  • Patent number: 8393364
    Abstract: In, for example, a direct methanol type fuelcell, fuel is allowed to be injected little by little when the fuel is injected and supplied from the outside to a fuel receiving part reduced in the amount of remaining fuel on the fuelcell body side and an electromotive part can be prevented from being damaged by keeping the pressure in the fuel receiving part at a fixed level or less when the fuel is injected. Specifically, when a fuel CL filled in a refuelling container C is injected into a fuel receiving part T in several lots, a fuel injecting operation is repeated in which the volume of the refuelling container C is shrunk and reduced to supply the fuel into the fuel receiving part T in a proper amount and then the original volume of the refuelling container is restored to thereby absorb the atmospheric gas in the fuel receiving part T, which makes it possible to inject fuel continuously without any hindrance to the injection of the fuel.

  • Patent number: 7935300
    Abstract: A manufacturing method of a resin container includes continuously supplying a base material resin forming a container body from a main extruder, discharging from a discharge portion provided in a die head a sub-material supplied from a sub-extruder so that the sub-material joins the base material resin, extruding a parison from a slit portion opened on an end side of the die head, and blow-molding the parison, thereby forming a coating layer which covers the whole or a part of the container body by using the sub-material. A thickness reducing portion in which a thickness is continuously reduced is formed in the coating layer while adjusting a resin pressure in a supply path of the sub-material fed from the sub-extruder by performing suck-back control which pulls back the sub-material from the discharge portion at an arbitrary timing when joining the sub-material with the base material resin.

  • Patent number: 7891963
    Abstract: A manufacturing apparatus of a resin container includes a main extruder which supplies a base material resin, and a sub-extruder which supplies a sub-material. The sub-material supplied from the sub-extruder is discharged from a discharge portion provided in a die head so that the sub-material joins the base material resin continuously supplied from the main extruder. A parison is then extruded from a slit portion opened on an end side of the die head, and subjected to blow molding, thereby forming a coating layer which covers the whole or a part of a container body formed of the base material resin by using the sub-material. A suck-back mechanism which pulls back the sub-material from the discharge portion is provided between the sub-extruder and the die head, and the discharge portion is provided in the vicinity of the slit portion in-the die head.

  • Publication number: 20090197150
    Abstract: A fuel cell cartridge for containing fuel for fuel cells, comprising a polyester resin, wherein after the fuel is contained and preserved at 60° C. for one week, a change of density at the bottom portion and the mouth portion is 0.01 g/cm3 or less. Even when methanol of a high concentration is contained, the fuel cell cartridge maintains excellent appearance effectively preventing the occurrence of whitening in the container and, particularly, at the mouth portion and the bottom portion thereof, and effectively suppressing a decrease in the shock resistance.

  • Patent number: 6477461
    Abstract: A navigation system for vehicles has a rewritable memory, which stores data of a plurality of locations, and searches the rewritable memory for a target location for use in guiding a travel route. When a user inputs a new location for registration, data of an input new location is stored in the rewritable memory in addition to original data of the plurality of locations. This data of new location may be stored by updating the original data or by adding separately from the original data. When a user requests a search for the target location by a name of the target location, the navigation system searches it alphabetically by referring to both data of the plurality of locations and the new location. The navigations system may be designed to conduct the location search by a facility type.
