Fig. 3 is a schematic view of another structure of the package according to the first embodiment of the present application after the package is opened.

Referring to fig. 1 to 3, an embodiment of the present application provides a packaging box, including: an inner case 1 comprising a first wall 11 and a second wall 12 opposite in a first direction X; a first liner 2 and a second liner 3 disposed opposite to each other along a second direction Y, the first direction X being perpendicular to the second direction Y; the first lining 2 and the second lining 3 are respectively connected with the two ends of the first wall 11 along the second direction Y in a bending way, the first wall 11 is provided with a containing opening 111, and the containing opening 111, the first lining 2 and the second lining 3 form a containing space; the first box cover 4 and the second box cover 5 are oppositely arranged along the second direction Y, and the first box cover 4 and the second box cover 5 are respectively connected with two ends of the second wall 12 along the second direction Y in a bending way; the first and second cap 4 and 5 cover the receiving opening 111 together.

In this embodiment of the present application, the first direction X and the second direction Y are perpendicular to each other, and when the package box of this embodiment of the present application is placed on a horizontal plane, the first direction X may be a vertical direction, and the second direction Y may be a horizontal direction. Considering that the package box generally adopts a cuboid shape, in the embodiment of the present application, the third direction Z is perpendicular to the first direction X and the second direction Y at the same time, and when the package box of the embodiment of the present application is placed on a horizontal plane, the third direction Z is another horizontal direction perpendicular to the second direction Y. The package of the embodiments of the present application may also be placed on a plane or curved surface inclined with respect to the horizontal.

The inner case 1, the first liner 2 and the second liner 3 are used for forming a containing space capable of containing packaged articles, so that the packaging box of the embodiment of the application can have a function of storing packaged articles. The first inner liner 2 and the second inner liner 3 are respectively connected with the first wall 11 along two ends of the second direction Y in a bending mode, one end, away from the first wall 11, of the bent first inner liner 2 is abutted to the second wall 12, one end, away from the first wall 11, of the bent second inner liner 3 is abutted to the second wall 12, and therefore the inner box 1, the first inner liner 2 and the second inner liner 3 can form a stable structure. Both the first liner 2 and the second liner 3 may be provided with a space capable of accommodating a portion of the packaged article. The first and second liners 2 and 3 are exposed at the receiving opening 111 of the first wall 11 such that the receiving opening 111, the first and second liners 2 and 3 form a receiving space. The user can place the packaged article in the accommodating space through the accommodating opening 111, and can take out the inner packaged article from the accommodating space through the accommodating opening 111. It should be noted that, in consideration of the placement of the packaged article into the accommodating space via the accommodating opening 111 or the removal thereof from the accommodating space, the size of the accommodating opening 111 should be appropriately larger than the size of the packaged article. In designing the package of the embodiment of the present application, the size and shape of the receiving opening 111 may be determined according to the size and shape of the packaged article.

The first box cover 4 and the second box cover 5 are used for shielding the accommodating space, and the packaged articles are limited to the inside of the packaging box of the embodiment of the application, so that the packaging box of the embodiment of the application has the function of protecting the packaged articles.
