Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Referring to fig. 1 to 3, the box-type packing box includes a box cover 1, a box body 3 and a hinge mechanism, wherein an inner container 7 is embedded in the box body 3 in practical application, and the inner container 7 can be used for holding the contents at a specific position. The hinge mechanism comprises a hinge piece 2 for hinging a box cover 1 and a box body 3; and a limiting member 4 for limiting the opening angle of the box cover 1.

The limiting part 4 is an inflexible limiting part, and the inflexible material that can be used includes but is not limited to cardboard, plastic board, silica gel board, metal foil. The limiting part 4 is provided with a fixed end 41 and a movable end 44, the fixed end 41 is glued on the inner surface of the box cover 1, the movable end 44 is arranged between the box body 3 and the inner container 7 in a penetrating mode by bypassing the hinge part 6 of the box cover 1 and the box body 3 and can move outwards or inwards correspondingly along with the opening or closing of the box cover 1, the movable end 44 is provided with a butting part 45, the box body 3 is provided with a blocking part 5, and the blocking part 5 is used for being matched with the butting part 45 to limit the end position of the outward movement of the movable end 44.

The limiting principle is as follows: in the process of opening the box cover 1, the movable end 44 of the limiting member 4 is pulled by the box cover 1 to move outward, and when the abutting portion 45 of the movable end 44 abuts against the blocking portion 5, as shown in fig. 3, the movable end 44 of the limiting member 4 cannot move outward continuously, so that the box cover 1 is kept at the current position. Because the limiting piece 4 is an inflexible limiting piece, in the process of closing the box cover 1, the limiting piece 4 is pushed by the box cover 1, and the movable end 44 moves inwards, so that the pulled part returns to the space between the box body 3 and the liner 7 in the opening process. Therefore, no matter the box cover 1 is in a completely opened state or in an incompletely opened state, the exposed part of the limiting piece 4 is flat and has no crease.

It will be appreciated that the above-mentioned effect can also be achieved by providing the blocking portion 5 on the inner container 7.

As shown in fig. 3, the limiting member 4 is further provided with a first fold 42 and a second fold 43 protruding toward the inside of the box body 3, when the box cover 1 is in the open state, the first fold 42 coincides with the opening edge of the box cover 1, and the second fold 43 coincides with the opening edge of the box body 3. The first fold 42 and the second fold 43 enable the pulled-out portion of the stopper 4 to more smoothly return between the box body 3 and the inner container 7 when the box cover 1 is closed.

As shown in fig. 1, the stopper 4 covers the entire inner surface of the rear side plate of the box cover 1. So that the inside of the box cover 1 is more neat and beautiful.

The hinge member 2 is preferably a plate-like structure, which may be used, but is not limited to, cardboard, plastic board, and silicone board. The plate-shaped structure is glued on the outer surface of the rear side plate of the box cover 1 and the outer surface of the rear side plate of the box body 3. More preferably, the plate-shaped structure covers the whole outer surface of the rear side plate of the box cover 1 and the whole outer surface of the rear side plate of the box body 3, so that the outer surface of the packing box is more flat and beautiful.

The hinge 2 is also preferably a flexible sheet material that may be used including, but not limited to, fabric, metal foil, and the like. The flexible sheet material is glued on the outer surface of the rear side plate of the box cover 1 and the outer surface of the rear side plate of the box body 3. More preferably, the flexible sheet material covers the whole outer surface of the rear side plate of the box cover 1 and the whole outer surface of the rear side plate of the box body 3, so that the outer surface of the packing box is more flat and beautiful.

The hinged part 2 adopts a non-hinged part 2, hinge marks and exposed gaps are not formed in the hinged part, and the appearance is flat and attractive.

The present invention has been described in detail with reference to the specific embodiments, and the detailed description is only for assisting the skilled person in understanding the content of the present invention, and can not be understood as the limitation of the protection scope of the present invention. Various decorations, equivalent changes and the like which are performed on the scheme by the technical personnel in the field under the conception of the invention are all included in the protection scope of the invention.
