A stackable container assembly having a base container with a container body having a bottom surface being configured for connecting the base container to a vehicle; and an anchor connected to the container body and being configured for inserting into a vehicle anchor fixture, the anchor including an anchor base being connected to the bottom surface of the container body; and an anchor lock extending from the anchor base; and an accessory container including an accessory body having an accessory bottom surface for selectively connecting the accessory container to one of the top surface of the base container and the vehicle such that the accessory container is arranged in one of stacked on top of the base container, and directly connected to the vehicle, the accessory container using a same connection arrangement for connecting to the one of the base container and the vehicle.

A fuel filler system for use in a vehicle is provided. The system includes a fuel filler tube, a locking bracket coupled to an inner surface of the fuel filler tube, and a closure device coupleable within the tube end and including an outer wall and a radially movable tab extending from the outer wall. The tab engages the locking bracket after rotation of the closure device from a first rotational position to a second rotational position to prevent rotation of the closure device relative to the locking bracket. The closure device further includes a web flexibly connecting the tab to the outer wall and a region of weakness defined in the web, such that upon forcible rotation of the closure device from the second rotational position to the first rotational position, the region of weakness facilitates separation of the web from the outer wall.

An improved, secure, anti-siphoning method and apparatus that can be fitted into any size fuel tank. The present invention includes a re-configured fuel cap that includes an electronic display, a touchpad for numerically inputting a security code for allowing a user to unscrew the fuel cap. In addition, a biometric reader is implemented to read a user's thumb print, and subsequently allowing the user to access the fuel tank.

A fuel tank cap includes a seal cap body and a detaching-proof unit. The cap body has a handheld wall and a surrounding wall that extends from the handheld wall and that is formed with an engaging groove. The detaching-proof unit includes a ring sleeve member and a connection member. The ring sleeve member has an outer ring wall that surrounds the surrounding wall, and a resilient wall that extends the outer ring wall and that is engaged resiliently with the engaging groove. The connection member is connected to the ring sleeve member to be connected to a cap installation portion of a vehicle body.

A stackable container assembly and vehicle having a stackable container assembly. The assembly includes a first pair of vehicle anchor fixtures; a second pair of vehicle anchor fixtures, a base container for selectively connecting to the first and second pairs of vehicle anchor fixtures; and an accessory container for selectively connecting to the base container and the first and second pairs of vehicle anchor fixtures. When connected to the vehicle, anchor fixtures of the first pair of vehicle anchor fixtures HAVE a separation therebetween equal to a separation between anchor fixtures of second pair of vehicle anchor fixtures, the base container being selectively connected to one of the first pair of vehicle anchor fixtures and the second pair of vehicle anchor fixtures, and the accessory container being selectively connected to the base container or the other one of the first and second pairs of vehicle anchor fixtures.

A vehicle fuel system according to the invention includes a fuel filler flap that blocks an opening of a fuel filler space to be openable and closable, a locking mechanism that regulates opening and closing operation of the fuel filler flap, and a detector that detects the opening and closing operation of the fuel filler flap. A controller is able to determine an operational state of the fuel filler flap multiple times within one driving cycle of a vehicle, which improves a frequency of diagnosing the operational state of the fuel filler flap and a stuck-closed state of the detector.

An embodiment fuel cap system includes a filler neck connected to a fuel pipe, a fuel cap having a cylindrical shape and able to be coupled to the filler neck by rotation, a sliding rod extending from an upper surface of the fuel cap in a shaft direction at an inside of the fuel cap and rotatable together with the fuel cap, a plunger including an upper end slidably coupled to the sliding rod in the shaft direction and a lower end including a coupling rod, and an inner ring on the filler neck and including a catching groove having an interior circumference on which the coupling rod is selectively engaged, wherein a rotation of the fuel cap is prevented when the coupling rod is engaged on the catching groove and the rotation of the fuel cap is possible when the coupling rod is disengaged from the catching groove.

A saddle-type vehicle includes a fuel tank, a tank cap that covers the refueling port provided in the fuel tank in an openable/closable manner, and an operation cable that performs an unlocking operation of the tank cap, wherein the fuel tank includes a first opening and a second opening that extend through the fuel tank, the path member is provided that passes through an interior of the fuel tank and connects the first opening and the second opening, the operation cable is arranged through an interior of the path member, and the operation cable protruding outward from the first opening is connected to the unlocking mechanism for unlocking the tank cap.
