Detailed Description

The utility model will be further described with reference to the drawings and specific examples.

As shown in figures 1 to 3 of the drawings,

a package box which is convenient to open and firm in buckling, comprising: a box body 1 and a box cover 2; the box cover 2 is hinged to one side of the box body 1 and can be buckled on the box body 1.

The top of the box body 1 is provided with a first buckling connection part 3 along the edge thereof, and the first buckling connection part 3 comprises a first extension convex part 31 and a first extension part 33.

As shown in fig. 4, the first extending protrusion 31 has a -shaped cross section extending upward from the top of the box 1, and has a plurality of fastening grooves 32 recessed inward toward the outer side of the box 1. The number of the buckling grooves 32 is nine, eight buckling grooves are arranged on two sides of the corner of the box body 1, and one buckling groove is arranged in the middle of the opposite side of the hinge edge of the box body 1 and the box cover 2.

The first extension 33 is formed by extending the end surface of the first extension protrusion 31 toward the outside of the case 1.

The top of the box cover 2 is provided with a second buckling connection part 4 along the edge thereof, and when the box cover 2 is closed, the second buckling connection part 4 is fit and attached to the outer side of the first buckling connection part 3. The second snap connection part 4 includes a second extension protrusion 41 and a second extension 43.

As shown in fig. 5, the second extending protrusion 41 has a -shaped cross section extending upward from the top of the box cover 2, and a plurality of fastening protrusions 42 adapted to the fastening grooves 32 are formed on the side surface of the second extending protrusion facing the inside of the box cover 2. The number of the buckling protrusions 42 is nine, eight buckling protrusions are arranged on two sides of the corner of the box cover 2, and one buckling protrusion is arranged in the middle of the opposite side of the hinge edge of the box cover 2 and the box body 1. When in buckling, the buckling groove 32 corresponds to the buckling protrusion 42, and the buckling protrusion 42 can be extruded into the buckling groove 32 by using the elasticity of plastic to tightly buckle the box body 1 and the box cover 2.

The second extension protrusion 41 is extended to the outside of the box cover 2 a small distance before being extended upward to fit the first extension protrusion 31.

The second extension 43 is formed by extending the end of the second extension protrusion 41 toward the outside of the box cover 2.

Further, the first extending protrusion 31 is formed with a first opening groove 35 at the center of two sides of the case 1. The second fastening connection portion 4 is concavely formed with a second opening groove 45 corresponding to the first opening groove 35. When the two-side opening type packaging box is buckled, the strength of the middle parts of the two sides of the packaging box is relatively weak due to the existence of the first opening groove 35 and the second opening groove 45, the box body 1 can be deformed by inwards pressing with fingers, and the box cover 2 can be automatically sprung open due to the elastic effect of plastic materials, so that a customer can conveniently open the packaging box.

Preferably, the first extending protrusion 31 and the four corners of the case 1 are concavely formed with first grooves 34. Second grooves 44 are formed in the second extending protrusions 41 and the four corners of the box cover 2 in a concave manner corresponding to the first grooves 34. When the first groove 34 corresponds to the second groove 44 in buckling, openings are formed at four corners of the packaging box so as to improve the air permeability of the packaging box; while the first and second grooves 34 and 44 may also enhance the deformability of the case body 1 and the case cover 2.

All the components are integrally formed by plastic suction.

The foregoing describes in detail preferred embodiments of the present utility model. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the utility model by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
