| 20110226777 | Fuel tank for motor vehicle - A fuel tank capable of strongly fusion-bonding a built-in part to an inner surface of an outer wall thereof while protecting the outer wall even when an impact, etc. are applied thereto. In the fuel tank for a motor vehicle, which is formed by blow molding, in which the built-in part is mounted, and which has the outer wall composed of a synthetic resin, a plurality of mounting members adapted to mount the built-in part to the fuel tank are provided on the built-in part so as to be fusion-bonded to the inner surface of the outer wall of the fuel tank. An abutment portion is formed on each of the mounting members for contacting the inner surface of the outer wall of the fuel tank, and an abutment surface and a plurality of abutment pins, each projecting from the abutment surface, are formed in the abutment portion. The abutment pin is formed into a columnar or frustum-shaped configuration, each having a circular or elliptical cross-section, and a diameter or a main axis of a projecting end of the abutment pin along with the height of the abutment pin from the abutment surface are formed less than the thickness of the outer wall of the fuel tank. | 09-22-2011 |
| 20100092600 | Blow molding device - A blow molding device capable of securely holding a built-in part in a prescribed position in an interior of a blow molded article with a compact equipment. The blow molding device includes a blow mold and a built-in part holding unit. The built-in part holding unit includes a holding rod adapted to hold the built-in part and arranged to freely advance and retreat to be removed from the blow mold. The blow mold includes a slide core in each of two mold members so as to freely advance and retreat relative to a cavity of the blow mold, and a drive control pin in each of mating faces of split two mold members, and the drive control pin and the slide core are linked with a linking member. The slide core is driven with the drive control pin such that when the blow mold is closed, the slide core retreats from an interior of the cavity to a molding surface defining the same at the same speed as the closing speed of the blow mold. | 04-15-2010 |
| 20100092593 | Blow molding device - A blow molding device capable of securely closing a lower end of a parison to prevent the parison from being crushed. The blow molding device includes a blow mold and a parison holding unit. The parison holding unit includes an inner holding plate adapted to be inserted in an interior of the lower end of the parison, and an outer holding plate adapted to hold an outer surface of the lower end of the parison, and the outer holding plate has a recess conforming to a configuration of the inner holding plate and is split into a plurality of holding plate members such that each of the split holding plate members is capable of sliding to hold the lower end of the parison. | 04-15-2010 |
| 20100051621 | Structure of opening section of fuel tank - A structure of an opening section of a fuel tank, which is capable of detaching a tank cap without damaging positioning projections provided in the tank cap. The opening section has a cylindrical portion extending outwardly from a tank main body, and a metallic annular tank cap engaging member having a plurality of engaging holes is attached to the cylindrical portion. A plurality of engaging claw parts of a metallic annular attaching member are engaged in the engaging holes of the tank cap engaging member to hold the tank cap with the attaching member and the tank cap engaging member. The tank cap has tank cap positioning projections, and the tank cap engaging member has positioning holes for insertion of the tank cap positioning projections, and at least one engaging claw part and at least one engaging hole are respectively made longer in a circumferential direction than remaining engaging claw parts and remaining engaging holes. | 03-04-2010 |
| 20090230133 | Fuel tank for motor vehicle - A fuel tank capable of attaching functional parts and tubes in an interior thereof. In a fuel tank for a motor vehicle, which is formed by blow molding for attachment of a built-in part in an interior thereof, and of which an outer wall composed of a synthetic resin has an opening, a functional part adapted to discharge fluid from the interior of the fuel tank or feed fluid therein is attached to the built-in part, a tube adapted to discharge fluid from the interior of the fuel tank or feed fluid therein is connected to the functional part, and a tube connector is attached to an end of the tube. A temporal holding connector is formed integrally with the built-in part, the tube connector is attached to the temporal holding connector, and after blow molding, the tube connector is detached from the temporal holding connector and is attached to a tank cap adapted to close the opening of the fuel tank. | 09-17-2009 |
| 20090162472 | Automotive fuel tank fabrication apparatus - An automotive fuel tank fabrication apparatus is provided. The automotive fuel tank has a blow mold and a built-in part holding unit. The built-in part holding unit includes a plurality of holding rods for holding a built-in part. The holding rods are made to freely advance and retreat in such a manner as to hold the built-in part in a position where the built-in part confronts cavities when the blow mold is opened and to retreat from the blow mold when the blow mold is closed with the built-in part left positioned in an interior of a parison. The holding rods are formed in such a manner that their diameters are reduced as they extend towards distal ends thereof and are inserted into insertion holes formed in the built-in part so as to hold the built-in part. | 06-25-2009 |
| 20090139994 | Automotive fuel tank - An automotive fuel tank is provided in which a plurality of mounting members are provided on a built-in part which are fusion bonded to an inner surface of an outer wall of the fuel tank so as to attach the built-in part in place in the fuel tank. An abutment portion is formed on the mounting member which is brought into abutment with an inner surface of the outer wall of the fuel tank. The abutment portion has formed thereon an abutment surface which is made to tightly stick to the inner surface of the outer wall of the fuel tank and elongated projections which project from the abutment surface, whose cross section at their distal end portions is of triangular shape and which penetrate into an interior of the outer wall of the fuel tank, and a height of an apex of the elongated projection from the abutment surface is in the range of 30% to 70% of a thickness of the outer wall of the fuel tank. | 06-04-2009 |
| 20090000686 | Fuel tank for automobile - The fuel tank for automobiles has the following structure. A main body of a fuel tank has an entire thickness of 3 to 8 mm and is formed of a surface layer, an outer main body layer, an outer adhesive layer, a barrier layer, an inner adhesive layer, and an inner main body layer that are formed in this order from-exterior. The surface layer and the inner main body-layer are formed from high density polyethylene. The outer main body layer is formed by using as a main material a recycled material of high density polyethylene, contains an inorganic filler having a particle diameter of 10 μm or less in an amount of 10 to 35 wt % with respect to a total weight of the outer main body layer, and has an thickness of 25% to 50% of the entire thickness of the main body. The outer adhesive layer and the inner adhesive layer is formed from a synthetic resin having an adhesion property for both of high density polyethylene and the barrier layer, and the barrier layer is formed from a synthetic resin hardly or never allow fuel permeation. | 01-01-2009 |
| 20080210692 | Opening structure of fuel tank and fabricating method thereof - There are provided a structure of an opening portion for integrally forming an opening portion to a fuel tank main body made of a thermoplastic synthetic resin having at least an outer layer, an inner layer and a middle layer therebetween and its fabricating method. The opening portion is constituted by a cylindrical portion and a folded portion folded in a hairpin shape. At least a portion of the folded portion includes a compression portion compressed from a direction orthogonal to an opening face and more thin-walled than other portion. An outer layer of the cylindrical portion is integrally embedded with a portion of a lid lock member made of a metal in a ring-like shape having a plurality of lock holes, an engaging claw portion of an attaching member made of a metal in a ring-like shape having the engaging claw portion engaged with the lock hole of the lid lock member is engaged with the lock hole, and a lid member for closing the opening portion is clamped by the opening portion and the attaching member. | 09-04-2008 |
