TECHNICAL FIELD

The present invention relates to a packing box which is easy to form and saves the space during transportation, and it is generally related to field of invention of the packing box field.

BACKGROUND TECHNOLOGY

Packing boxes are very widely used in many areas, for the purpose to withhold and secure articles inside, including everyday articles like food, cosmetics, and gifts, etc.

The packing boxes can not only provide excellent support and protection for the articles within, but ensure orderly arrangement and increase exterior esthetical value of the product. When the packing box is in use, as a 3-dimensional body, it provides accommodation space for the articles within. However, when the packing boxes are not in use, the accommodation space takes too much unnecessary storage space. Additionally, in the absence of the articles inside, the empty packing boxes can sustain very little pressure on their own. When a great amount of packing boxes needs to be transported, the packing boxes cannot be heavily stacked, otherwise, the packing boxes will be easily damaged, besides that the empty packing boxes take and waste a lot of storage space.

SUMMARY OF THE INVENTION

The invention aims to provide a packing box to solve the technical problem that the packing box is not easy to store and transport because of the accommodation space thereof.

To achieve the above-mentioned objective, the invention provides the following technical solutions.

A packing box comprises a base surface, side surfaces and accommodation space or receiving compartments. The side surfaces are arranged around the base surface, and form a one-piece planar structure with the base surface.

The side surfaces and the base surface are provided with first set of folding marks, which are configured to be used so that when the side surfaces and the base surface are folded along the set of folding marks, an enclosed body of the packing box is formed.

A plurality of holes is arranged on the base surface, and the accommodation space or receiving compartments or compartments are fixed on the base surface, with the holes used as openings thereof.

Each accommodation space or compartment is surrounded by a plurality of wall surfaces, the wall surfaces include unparallel wall surfaces, which are unparallel to the base surface when the accommodation space or receiving compartments or compartments are unfolded, and parallel wall surfaces, which are parallel to the base surface when the accommodation space or receiving compartments or compartments are unfolded, and a plurality of second folding marks are provided on the unparallel wall surfaces so that corresponding wall surfaces can be fold or unfold according to the plurality of the second folding marks; wherein, when the unparallel wall surfaces are folded, the internal cavities of the accommodation space or receiving compartments or compartments disappear and the accommodation space or receiving compartments or compartments are retracted, and when the unparallel wall surfaces are unfolded, the accommodation compartments are unfolded or revealed.

Further, in the present invention, the wall surfaces of each accommodation space or compartment comprise first wall surfaces and second wall surface, wherein the first wall surfaces are the unparallel wall surfaces, the second wall surface is connected with the first wall surfaces and is the parallel wall surface, and the second folding marks parallel to the base surface are arranged on the first wall surfaces.

Further, in the present invention, the first wall surfaces are folded toward the inside of the accommodation space or receiving compartments or compartments.

Further, in the present invention, the wall surfaces of each accommodation space also comprise third wall surfaces which are fixedly connected to the base surface and form an one-piece structure with the base surface, third folding marks are disposed between the third wall surfaces and the base surface, are arranged along partial edges of the holes corresponding to the accommodation space or receiving compartments or compartments, and are used to fold the third wall surfaces along the third folding marks toward the inside of the accommodation space or receiving compartments or compartments to unfold the unparallel wall surfaces and fold the third wall surfaces along the third folding marks toward the base surface to fold the unparallel wall surfaces.

Further, in the present invention, the edges of the third wall surfaces adjacent to the third folding marks, at least, sweep through the first wall surfaces and the second folding marks thereon on the path where the third wall surfaces are folded toward the inside of the accommodation space or receiving compartments or compartments.

Further, in the invention, the radial length of the third wall surfaces along the third folding marks as the axes is equal to the depth of the accommodation space or compartments with the holes as the openings.

Further, in the invention, the hardness of the first wall surfaces of the accommodation space or compartments is lower than the hardness of the third wall surfaces.

Further, in the invention, the hardness of the base surface is higher than or equal to the hardness of the third wall surfaces.

Further, in the invention, the side surfaces comprise first side surfaces and second side surfaces which are arranged at interval and match mutually when being folded to form the vertical surfaces of the packing box;

Wherein, the first side surfaces at least comprise surfaces A, surfaces B and surfaces C which are connected in sequence, the first side surfaces are connected to the base surface through the surfaces A, first folding marks are arranged between the first side surfaces and the base surface, the surfaces A and the surfaces B have the same size, between which fourth folding marks are arranged, and fifth folding marks are arranged between the surfaces B and the surfaces C; the first folding marks, the fourth folding marks and the fifth folding marks are parallel mutually.

The first side surfaces are folded toward the inside of the base surface in sequence to form the first folding marks, the fourth folding marks and the fifth folding marks to realize folding of the first side surfaces, the surfaces A and the surfaces B overlap mutually, and the surfaces C are attached on one side of the base surface.

First bulges are arranged on the base surface near the first folding marks, with the thickness larger than the thickness of the surfaces C.

After the first side surfaces are folded, the outer edges of the surfaces C parallel to the fifth folding marks abut against the outer side walls of the first bulges close to the first folding marks.

The invention also provides a method of using the packing box, through which the unfolded packing box is assembled.

Side portion of the packing box: the side surfaces are folded toward the base surface along the first folding marks, so that a space body is formed for the packing box.

Accommodation space or receiving compartments of the packing box portion: the third wall surfaces are folded along the third folding marks toward the inside of the accommodation space or receiving compartments through the holes, so as to unfold the unparallel wall surfaces in the accommodation space or receiving compartments to form the accommodation space or receiving compartments.

Further, in the present invention, when the side portion are folded, the first side surfaces are folded toward the inside of the base surface, in sequence, folding along the first folding marks, the fourth folding marks, and the fifth folding marks, so that the surfaces A and the surfaces B overlap mutually, and the surfaces C are attached on one side of the base surface; the second side surfaces are folded toward the inside of the base surface through the first folding marks and folded toward the gaps between the surfaces A and the surfaces B through the sixth folding marks, so that the turn-over edges are located in the gaps the surfaces A and the surfaces B.

BENEFICIAL EFFECTS

As it can be seen from the above technical solutions, the technical solutions of the present invention provide a packaging box and a method of using the same, which have the following beneficial effects.

1. The accommodation space or receiving compartments and the side surfaces thereof can be completely flattened, so that the side walls, the side surfaces and the base surface of the accommodation space or receiving compartments are folded in a nearly parallel way, transportation and storage are easy, the space occupied is reduced, and the packing box cannot be crushed during transportation and storage.

2. The folding operation is easy, the side walls and the wall surfaces can be folded and unfolded through simple pushing, the packing box can be formed easily, and the time used for folding are reduced; after the third wall surfaces are folded toward the accommodation space or receiving compartments, the wall surfaces of the accommodation space or receiving compartments are automatically locked in the vertical state through certain elasticity and friction force of the material, without the need of fixing measures like adhesives; after articles are positioned in the formed accommodation space or receiving compartments, the gravity of the contained articles increases the stiffness and steadiness of the wall surfaces of the accommodation space or receiving compartment.

3. Through the folding, the vertical surfaces and the accommodation space or receiving compartments of the packing box are well fixed, and thus the steadiness of the formed packing box can be ensured.
