A package 1 includes: a package body 2 having an open end 21a; a lid member 3 that is pivotably coupled to a rear opening edge of the open end 21a by means of a hinge 27 and opens/closes the open end 21a; and a flat plate spring member 4 placed inside of the package 1, the flat plate spring member 4 having one end fixed to an inner surface of the package body 2 and having another end fixed to an inner surface of the lid member 3. The flat plate spring member 4 includes a bend line 45 parallel to the hinge 27, a first region portion 41, and a second region portion 42. When the first region portion 41 and the second region portion 42 are bent relative to each other at a boundary along the bend line 45 in conjunction with an opening/closing action of the lid member 3, a posture of the flat plate spring member 4 is switched between: a first tilted state in which the second region portion 42 is tilted frontward with respect to the first region portion 41; and a second tilted state in which the second region portion 42 is tilted rearward with respect to the first region portion 41. |
