A plastic tank is comprised of two parts, a base and a top, that are permanently joined to each other by welding at a circumferential joint formed by two mating flanges of the parts. Fusion weld elements are captured on the faying surfaces of the flanges of the assembled parts, and the elements melted by internal heating of metal portions of the elements. Before heating of the elements, the flanges are gripped by a clamp which applies a resilient force which, during welding, causes the flanges to move toward each other and thereby a good weld joint is formed.

A cap protector for protecting a cap on a container includes a plurality of axial fins extending from a common point. Each axial fin includes a body extending between an inner edge and an outer edge, and a cap-engaging lip defined on the inner edge that is configured to selectively engage a cap of a container. The plurality of axial fins may be movable from a disengaged position to an engaged position, wherein in the engaged position the cap-engaging lip of each of the plurality of axial fins engages the cap of a container.

A stowage compartment for a vehicle includes a bin, a bin frame, and a door assembly. The bin includes an opening and an interior compartment. The bin frame comprises an opening, a first and second door guide, and a first and second latch feature. The door assembly is capable of locking in a closed position as well as an open position. The door is able to be operated by one hand.

A closure for a lid that has at least one opening may include an activator pivotally coupled to the lid, a cover pivotally coupled to the lid, and a connecting member pivotally coupled to the activator and the cover. The activator, the cover and the connecting member may form an over center latching mechanism. In addition, the activator may be pivotally connected to the lid about a first axis of rotation, the cover may be pivotally connected to the lid about a second axis of rotation, the connecting member may pivotally connected to the activator about a third axis of rotation, and the connecting member may be pivotally connected to the cover about a fourth axis of rotation. The distance between the first and second axes of rotation may be constant, and the distance between the third and fourth axes of rotation may change as the cover is moved.
