Example one

As shown in fig. 1 to 8, a packaging box according to a first embodiment of the present invention includes an upper casing 100 and a lower casing 200, a containing cavity is defined between the upper casing 100 and the lower casing 200, the upper casing 100 has a first end and a second end which are oppositely disposed, the first end of the upper casing 100 is rotatably connected to the lower casing 200, an opening and closing portion 600 is formed between the second end of the upper casing 100 and the lower casing 200, and the upper casing 100 has a degree of freedom to rotate around the first end; the accommodating cavity is internally provided with a limiting part 300, a limiting cavity for accommodating the elastic product 700 is limited between the limiting part 300 and the opening and closing part 600, and the elastic product 700 is blocked in the limiting cavity by the limiting part 300, so that the phenomenon that the elastic product 700 is damaged due to the fact that the elastic product 700 is clamped when the upper shell 100 and the lower shell 200 move relatively is avoided.

Based on above technical scheme, when the packing carton is taken to take the elastic product 700 of placing in the packing carton when needs open, the user only need squeeze the surface that the packing carton is located first end, make upper housing 100 rotate around the first end of upper housing 100, the portion 600 that opens and shuts of the second end of upper housing 100 and lower housing 200 will open and form the opening this moment, before upper housing 100 and lower housing 200 are opened simultaneously, because upper housing 100 makes the gas that holds the intracavity compressed for lower housing 200 motion, make the pressure increase that holds the intracavity, when portion 600 opens and shuts, under gaseous promotion, elastic product 700 is popped out or partly pops out from the opening play, supply the user to use, the user only needs the one hand can open the packing carton and takes out the elastic product 700 of placing wherein, thereby convenient to use person operates, the operation difficulty is reduced, user's comfort level is improved.

In some embodiments of the present application, the distance between the position-limiting part 300 and the opening/closing part 600 is smaller than the outer diameter of the elastic product 700. Thus, the elastic product 700 is placed in the accommodating cavity in a compressed state, and when the opening and closing portion 600 is opened, the elastic force of the elastic product 700 restoring to its original state helps the elastic product 700 to be ejected from the inside of the packaging box.

Optionally, the number of the limiting parts 300 is one or more, and the limiting parts 300 are at least any one of limiting protrusions, limiting plates and limiting blocks arranged in the accommodating cavity. The person skilled in the art can combine and use various of the above components as required to limit the position of the elastic product 700.
