Problems solved by technology

This kind of carton has additional adhesive requirements, which increases its production cost and environmental cost in disguise, and increases the trouble of gluing and sealing for users
At the same time, such cartons are prone to repeated disassembly and secondary packaging, and cannot guarantee the privacy of the products in the packaging during transportation, which poses a safety hazard for some products involving commercial secrets or personal privacy.

Embodiment 1

[0031] In the present invention, the packing box is a cube, and the box body and the box cover are cut and folded from a piece of paper material (corrugated paper); wherein:

[0032] The bottom surface of the box body is rectangular, and its left and right sides respectively extend out a rectangle as the left and right side walls of the box body, namely the left and right outer protective layers 1; the left and right outer protective layers 1 corresponding to the left and right outer layers Then the locking layer 2 is integrally extended outwards; the locking layer 2 is folded inward, and a gap 5 is provided on it;

[0033] A rectangle is integrally extended from the bottom surface and the lower edge of the box body, respectively, as the front and rear side walls of the box body;

[0034] A rectangular inner cover surface 7 is integrally extended outward from the lower edge of the front side wall, and an inner protective layer 6 is integrally extended outward from the left and...

Embodiment 2

[0039] In the present invention, the packing box is a cube, and the box body and the box cover are cut and folded from a piece of paper material (corrugated paper); wherein:

[0040] The bottom surface of the box body is rectangular, and a rectangular surface is integrally extended outward from the front side as the front side wall; the upper side of the front side wall is integrally extended outward with a surface that is the same as the bottom surface as the top surface of the box cover; the top surface is the same as the front side. On the side corresponding to the connecting edge of the side wall, a rectangular surface is integrally extended outward as the inner layer 4; on the inner layer 4, on the side corresponding to the connecting edge of the front side wall, two parts on the left and right sides are integrally extended outward. a locking layer 3, the locking layer 3 is folded outwards;

[0041] A rectangular surface integrally extends outward from the rear edge of th...

Embodiment 3

[0045] In the present invention, two sheets of paper material are cut and folded to form a box body with a locking layer 3 and an inner layer 4 and a box cover with a locking layer 2 and an outer protective layer 1 .

[0046] The inner layer 4 is directly used as the left and right side walls of the box body; there are four locking layers 3, which are respectively arranged on the left and right sides of the top of each inner layer 4, and are integrally connected with the inner layer 4 and folded outwards. The outer protective layer 1 is used as the left and right side walls of the box cover. The locking layer 2 is integrally connected with the upper part of the outer protective layer 1 and is folded inward; The left and right sides of the bottom of the stop layer 2. like Figure 4 shown.

[0047] The side wall of the box cover is covered outside the side wall of the box body.

[0048]When the present invention is used, the elastic deformation and recovery characteristics of...

Abstract

The invention belongs to the technical field of packaging, and particularly discloses a locking mechanism of a packaging box. The mechanism comprises a concave-shaped buckling groove formed in a side wall of a box body/a box cover and a corresponding convex-shaped locking buckle arranged in the side wall of the box cover/box body; the shape and the position of the concave-shaped buckling groove is matched with the shape and the position of the convex-shaped locking buckle; when the box cover is closed on the box body, the convex-shaped locking buckle can be embedded into the concave-shaped buckling groove to form an inverse buckle so that the box body cannot be opened. When the locking mechanism is used, an elastic material is utilized, after the box cover is closed, the convex-shaped lock buckle is bounced into the concave-shaped buckling groove to form the inverse hook, so that the box cover can be locked tightly without using glue and adhesive tape, so that the security of the goods in the box is protected. The locking mechanism has a simple structure; the sealing of the locking mechanism is adopted by utilizing a physical method of a built-in clamping buckle, so that the privacy of the products in the box can be fully ensured, and the packaging box is sealed without using any binding agent or adhesive tape, so that the cost is low and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of packaging, and in particular relates to a locking mechanism for a packaging box. Background technique [0002] As the process of global economic integration continues to accelerate, trade barriers between countries continue to be eliminated, international trade and domestic trade activities become more active, production, business and social activities tend to be more efficient and fast-paced, time value is more and more important, a large number of The rapid delivery of samples, documents, business letters and materials has provided a large supply of goods for the express delivery industry, and also greatly promoted the market's demand for packaging boxes. This demand includes not only the demand for the number of packaging boxes, but also the requirements for various functions of the packaging boxes. [0003] As a shipping necessities with great market demand, the production cost of packaging boxes is ...
