Abstract

An elongate article holding package for a wiper blade having a pair of package panels with at least one of the panels including a blade beam receiving seat and a support flat upon which part of the blade rests during packaging. When closed, the flats position and can clamp the blade therebetween. In a preferred embodiment, both panels are so configured and preferably include one or more longitudinal stiffeners that oppose bending moments created by force transmitted to the package by the blade beam. The package preferably is of tri-fold construction having a spine that is spaced from and protects the wiper element. The spine preferably includes at least a plurality of spaced apart longitudinally extending stiffeners. One or more stiffening flanges preferably are also provided. When closed, the panels and spine advantageously cooperate with each other to increase package crush and bending resistance.

10. The wiper blade package of claim 9, wherein the wiper blade cradle and wiper blade beam seat formed in one of the package halves is aligned with and overlies the wiper blade cradle and wiper blade beam seat formed in the other one of the package halves when the package halves are disposed in the closed position.

11. The wiper blade package of claim 10, wherein the plurality of releasable latching arrangements each comprise a snap integrally formed in one of the package halves that releasably engages a snap receiver integrally formed in the other one of the package halves, wherein each wiper blade beam seat further comprises a land disposed between the lip and the one of the snap and snap receiver.

12. The wiper blade package of claim 9, wherein the wiper blade cradles of both package halves clamp a wiper blade received in one of the wiper blade cradles when the package halves engage one another in a closed position defining a recess in which a wiping tip of a wiper blade working element is disposed without contacting any part of either one of the package halves.

13. The wiper blade package of claim 7, wherein the end piece has a pair of elongate stiffening ribs formed therein that each oppose an elongate stiffening rib formed in an adjacent one of the package halves when the package halves are disposed in the closed position.

14. A wiper blade package in combination with a beam-type wiper blade comprising:

(a) the beam-type wiper blade comprising an elongate curved beam, an elongate wiping element that includes a spine attached to the beam and a working segment with a wiping tip extending outwardly therefrom;

(b) the wiper blade package comprising a pair of package halves attached by a hinge arrangement and movable between an open position where it accepts the beam-type wiper blade and a closed position where the beam-type wiper blade is retained therebetween, wherein the package halves are constructed and arranged to engage the beam of the beam-type wiper blade in a manner that retains the beam-type wiper blade in a substantially straight condition without any part of the package contacting the wiping tip of the wiping element.

15. The wiper blade package and beam-type wiper blade combination of claim 14 wherein the wiper blade package further comprises a releasable latching arrangement that enables the package halves to be releasably retained in the closed position.
