A packaging case for a windshield wiper blade includes an elongated wiper blade receiving section including a perimeter wall defining a blade-retaining channel. The perimeter wall includes inner and outer wall segments. At least one aperture is formed within the outer wall segment of the perimeter wall. An elongated cover section is pivotally coupled to wiper blade receiving section and configured to pivot between an open state and a closed state. The elongated cover section includes first and second lateral walls and first and second end walls defining a cover compartment that fits over the elongated wiper blade receiving section. At least one projection is formed on an inner surface of the first lateral wall for engaging the at least one aperture formed within the outer wall segment of the contoured wall, thereby retaining the cover section over the wiper blade receiving section.
