Preferably, one end of the card, which is far away from the side wall of the groove, is tilted upwards to form a fin.

Through adopting above-mentioned technical scheme, because the flange is circular-arc setting, consequently the card can block in the lower extreme of flange to promote the complex steadiness between flange and the recess.

Preferably, the outline shape of the card is set to be arc.

Through adopting above-mentioned technical scheme, when lid and box body cooperation, the flange need with the recess cooperation, when the flange gets into the recess inside, the flange can promote curved card and buckle to along with the continuous removal of flange, area of contact between flange and the card reduces gradually, so that the smooth cooperation of flange and recess.

Preferably, the lower end of the side wall of the groove where the card is located is further provided with a shifting sheet, the shifting sheet extends to one side of the groove far away from the center of the box cover, and the card is connected with the shifting sheet.

Through adopting above-mentioned technical scheme, the staff can be through stirring the plectrum to the control card turns over and rolls over, so that flange and recess break away from, thereby the lid of being convenient for breaks away from with the box body, promotes the convenience that the packing box used.

Preferably, the plectrum is provided with a reinforcing convex rib.

Through adopting above-mentioned technical scheme, strengthen the bending strength that the bead can increase the plectrum to the card upset is effectively stirred to the staff, so that lid and box body break away from.

In summary, the present application includes at least one of the following beneficial technical effects:

1. when the flange is matched with the groove, the clamping block can limit the lower end of the flange so as to fix the box body, the side wall of the groove corresponding to the clamping block is provided with a recess, a reinforcing rib is formed between every two adjacent recesses, the side wall of the groove can be reinforced, the matching stability between the clamping block and the flange is improved, and the matching firmness between the box body and the box cover is improved; the convenience of the use of the packing box is improved;

2. the clamping piece arranged on the side wall of the groove can limit the lower end of the flange, so that the matching firmness between the box body and the box cover is further improved;

3. recess lateral wall lower extreme still is provided with the plectrum to the card is connected with the plectrum, and the staff can be through stirring the plectrum, thereby the control card turns over and rolls over, so that flange and recess break away from, so that lid and box body of being convenient for break away from, promote the convenience that the packing box used.

Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses packing box convenient to use. Referring to fig. 1 and 2, the convenient-to-use packing box includes a box body 1 and a box cover 2 fitted over the box body 1. The upper end of the side wall of the box body 1 is provided with a flange 11, and the flange 11 is arranged around the periphery of the box body 1 and extends to the outer side of the box body 1. The peripheral side of the box cover 2 is provided with a groove 21 matched with the flange 11. The flange 11 can be fitted into the groove 21 when the cap 2 is fitted over the case body 1.

Referring to fig. 1 and 2, the cross-section of the flange 11 is arcuate and the contour of the cross-section of the groove 21 is also arcuate so that the flange 11 conforms to the side walls of the groove 21. The lateral wall of recess 21 is upwards protruding and form a plurality of rib 22, and a plurality of rib 22 is along recess 21 length direction evenly distributed to every rib 22 all sets up along recess 21 width direction, and rib 22 can effectively promote the intensity in 2 edges of lid, reduces the deformation volume that its edge department produced when lid 2 atress, thereby promotes recess 21 and flange 11 complex stability.

Referring to fig. 2, the side wall of the groove 21 away from the center of the box cover 2 protrudes into the groove 21, so that a plurality of blocks 23 are formed inside the groove 21, and a recess is correspondingly formed on the outer side wall of the groove 21. A reinforcing rib is formed between two adjacent depressions, so that the side wall of the groove 21 can be reinforced. The plurality of blocks 23 are distributed along the length direction of the groove 21, and two adjacent blocks 23 are arranged at intervals. The clamping block 23 can be abutted against the lower end of the flange 11, so that the flange 11 is limited, and the stability of the fit between the box cover 2 and the box body 1 is improved.

Referring to fig. 2 and 3, in the present embodiment, the box body 1 and the box cover 2 are both square, and may be provided in a multi-deformation or circular shape. Four corners of the box cover 2 are provided with poking pieces 24, the poking pieces 24 are positioned at the lower ends of the side walls of the grooves 21, and one side of each poking piece 24 extends to one side of the horizontal direction of the box cover 2. The pick 24 is also provided with a reinforcing convex rib 241 which can improve the strength of the pick 24.

Referring to fig. 3, each of the shifting pieces 24 is correspondingly provided with a clamping piece 25, and the clamping piece 25 is located on the side wall of the groove 21 away from the center of the box cover 2. The card 25 is arcuate in profile and the end of the card 25 remote from the side wall of the recess 21 is upwardly turned to form a fin 251.

Referring to fig. 4, when the flange 11 is mated with the groove 21, the flange 11 will be trapped between the tabs 25 and the side walls of the groove 21, so that the tabs 25 can secure the flange 11. And when the staff needs to open the box cover 2, the card 25 can be turned downwards only by pulling the poking piece 24, so that the flange 11 is separated from the groove 21.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
