In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a simple and easy packing carton, packing box body and lid, the box body is by bottom plate, left side board, preceding curb plate, right side board and each adjacent side of posterior lateral plate along the structure that links to each other and form and have certain appearance chamber each other, the rear side edge of lid is connected through a weak link with the upside edge of posterior lateral plate, be equipped with spacing piece between posterior lateral plate and the lid, set up three easy broken line parallel with the posterior lateral plate upside edge on the spacing piece, the definition three easy broken line is easy broken line, well easy broken line and lower easy broken line in last, the spacing piece be located the part of easy broken line upside with the lower surface rigid coupling of lid, spacing piece be located the part of easy broken line below down and posterior lateral plate medial surface rigid coupling, and when lid and posterior lateral plate are located the coplanar, it is three easy broken line place regional spacing piece forward protruding.

Further, the included angle of the protrusion towards the weak connection part is 140-175 degrees.

Further, the front side edge of lid is equipped with downwardly extending's front shroud, front shroud and preceding curb plate or left side board or the contact setting of at least one interference fit in the right curb plate.

Furthermore, a support frame is arranged in the box body, and the inner side of the front cover plate is in interference fit contact with the support frame.

Furthermore, a display window is arranged in the middle of the cover body.

Furthermore, the weak connection part is formed by compounding two or more bendable flexible connection layers.

By adopting the technical scheme, the beneficial effects of the utility model are that: the simple packing box improves the technical problems of lid positioning by using a connecting belt, the belt of the packing box can leak out of the box when the simple packing box is opened and closed, the aesthetic property is poor, and the lid is not tight, through arranging the limiting sheet between the back side plate and the cover body, when the lid is opened to 100 degrees, the connecting layer can form tension on the lower surface of the cover body of the packing box and the inner surface of the back side plate, the cover body of the packing box is prevented from being turned backwards continuously, the desktop space can be saved, the display effect is improved, when the lid is closed, the limiting sheet in the area of the easy folding line is protruded forwards, the product appearance cannot be influenced, through the matching of the inclined structure of the bottom side plate and the left and right ends of the front-end clamping plate, when the cover body is closed, the slopes of the left and right ends of the front-end clamping plate are in interference fit with the, the cover is prevented from being automatically opened under the action of the elastic force at the rear end; furthermore, through setting up the product show window, can still carry out certain show to the product when the packing carton lid is closed, improve the aesthetic property.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1-3, a simple packing box, packing box 1 and cover 2, wherein the box 1 is a cuboid structure formed by connecting adjacent side edges of a bottom plate 11, a left side plate 12, a front side plate 13, a right side plate 14 and a rear side plate 15, the rear side edge of the cover 2 is connected with the upper side edge of the rear side plate 15 through a weak connection part, a limiting sheet 3 is arranged between the rear side plate 15 and the cover 2, three easy folding lines parallel to the upper side edge of the rear side plate 15 are arranged on the limiting sheet 3, the three easy folding lines are defined as an upper easy folding line, a middle easy folding line and a lower easy folding line, the easy folding lines are dotted lines formed by punching holes, the part of the limiting sheet 3 positioned at the upper side of the upper easy folding line is bonded with the lower surface of the cover 2 through glue, the part of the limiting sheet 3 positioned below the lower easy folding line is bonded with the inner side surface of the rear side, and when the cover body 2 and the rear side plate 15 are positioned on the same plane, the three limiting pieces 3 in the area where the easy folding lines are positioned protrude forwards, and the middle part of the cover body is provided with a display window 5.
