Wiper blade package

A wiper blade package (100, 200) has a mouth portion (112) that is openable by being pressed in a lateral direction. The wiper blade package has a first panel (120), a second panel (130, 230) opposed to the first panel, and a pair of side panels (140a, 140b). The first panel is bendable around a bend line (121) extending in a longitudinal direction and has a lid flap (150) at its end. The lid flap is foldable around the bend line and is pivotable around a hinge line (122) intersecting the bend line. The second panel has an engagement flap (170) at its end. The lid flap engages a free end (171) of the engagement flap at its free end (151) and thereby closes a receiving portion (110) in which a wiper blade (10, 20) is received. The lid flap is pivoted from the engagement flap by pressing the side panels toward the receiving portion and thereby opens the receiving portion.
