Abstract

The invention discloses a package case. The package case comprises a case body, a first upturning cap, a second upturning cap, a reinforcing plate and a lifting handle part. The case body comprises an opening and the opening comprises a first edge and a second edge which are arranged opposite to each other. One end of the first upturning cap is connected with the first edge in a foldable manner and one end of the second upturning cap is connected with the second edge in a foldable manner. A lifting handle installing inserting tongue a is formed on the second upturning cap. The reinforcing plate comprises a lifting handle installing inserting tongue b. The lifting handle installing inserting tongue a and the lifting handle installing inserting tongue b are inserted into a lifting handle ring of the lifting handle part in the opposite directions. The lifting handle part extends out above the first upturning cap from a lifting handle extending opening of the first upturning cap. According to the package case, an inter-complementary interdigitating structure is formed in strength by the reinforcing plate of the second upturning cap for making up for the weak spot that a single E-shaped structure is stressed unevenly, and therefore the strength of the package case can be increased in partial and the two ends of the lifting handle of the package case can be stressed evenly without the need for changing the structure and the strength of the lifting handle, so that the condition can be solved fundamentally that the lifting handle comes off.
