Abstract: A lid usable with a beverage container and a refillable reservoir positioned within the container. The lid has a mixing chamber, an additive passageway extending between the mixing chamber and the reservoir, and a beverage passageway extending between the mixing chamber and the container. A slider gate is movable between a first position closing communication between the additive passageway and the mixing chamber, but providing communication between the beverage passageway and the mixing chamber, a second position providing communication between the additive passageway and the mixing chamber, and between the beverage passageway and the mixing chamber, and a third position providing communication between the additive passageway and the mixing chamber, but closing communication between the beverage passageway and the mixing chamber.

Abstract: Jump rope handles are described. In an embodiment, a speed rope includes a handle having a head rotationally coupled to a grip to rotate about a first axis, and a rope hinge rotationally coupled to the head. The rope hinge has a single degree of freedom relative to the head, and the single degree of freedom can be rotation of the rope hinge about a second axis. The rope hinge may include a cylindrical outer surface mounted in a pivot hole of the head to constrain movement of the rope hinge to rotation about the second axis. Accordingly, a rope held by the rope hinge can pivot about the second axis while simultaneously swinging around the first axis. Other embodiments are also described and claimed.
