Abstract: A screw-type bottle neck having areas of reduced wall thickness is provided. The bottle neck includes a neck opening having a neck opening axis, a neck interior surface, and a neck exterior surface. The neck exterior surface includes at least one spiral thread portion. The bottle neck has at least one area of first neck thickness having a first neck thickness, and at least one area of second neck thickness having a second neck thickness. The second neck thickness is greater than the first neck thickness. The difference between the first neck thickness and the second neck thickness allows for a substantial reduction in the amount of material required to manufacture the bottle neck.

Abstract: A container carrier system for securing and carrying at least two containers is provided. The container carrier system generally includes a handle and at least two retainer rings. The handle has a carrying portion and at least two attachment portions. A single retainer ring is secured to a single container, and each retainer ring includes at least one handle receiver for receiving and retaining a single attachment portion of the handle. Each attachment portion includes an upper leg-stop transition portion joined to an upper attachment stop. A lower attenuated attachment leg is joined to the upper attachment stop and terminates in a lower attachment stop. Each handle receiver includes first and second resilient jaws that define a receiver mouth and a receiver central opening. The resilient jaws are movable between a minimum retaining position and a maximum receiving position to facilitate securement of an attachment portion to a handle receiver.
