As shown in fig. 1 to 5, a foldable paper box according to an embodiment of the present invention includes a body 1 and an adhesive tape 2. In this embodiment, the carton is mainly used for packaging small goods.

The body 1 is integrally cut and folded from a piece of paperboard, and the weight of the paperboard can be between 200 and 450 g. The body 1 comprises a bottom plate 11, a side plate structure 12 connected with the bottom plate 11 and a cover plate structure 13 arranged above the bottom plate 11, wherein the side plate structure 12 comprises a front side plate 121, a rear side plate 122 and a left side plate 123, a right side plate 124 which are arranged oppositely, the four side plates are connected with the bottom plate 11 and are perpendicular to the bottom plate 11, and crease lines 19 are arranged at the joints. The four side plates are formed by folding along the crease lines 19, so that the process of sticking the side plates to form the barrel is omitted.

The cover structure 13 includes an upper cover 131 connected to the front side plate 121, a lower cover 132 connected to the rear side plate 122, a left cover 133 connected to the left side plate 123, and a right cover 134 connected to the right side plate 124. The four cover plates are respectively perpendicular to the four side plates. In this embodiment, the main body 1 is rectangular, two larger surfaces are used as the bottom plate 11 and the cover plate, and the large opening is convenient for packing and placing objects to be packed, especially for assembling and packaging of automatic equipment.

The adhesive tape 2 is provided on the upper cover plate 131 for adhesively fixing the upper cover plate 131 to seal the carton. The adhesive tape 2 may be a double-sided tape. The adhesive tape 2 is positioned at the edge of the upper cover plate 131. Through will paste area 2 and locate upper cover plate 131 in advance, can make things convenient for the joint sealing, the user need not to use in addition the joint sealing to glue.

The two sides of the lower cover plate 132 are provided with the hollow areas 3 to expose the left cover plate 133 and the right cover plate 134, so that the upper cover plate 131 is bonded with the left cover plate 133, the right cover plate 134 and the lower cover plate 132 through the adhesive tape 2, and thus the left cover plate 133 and the right cover plate 134 can be limited to be stressed and extend to the two sides, namely, the displacement of the left cover plate 133 and the right cover plate 134 is limited, and the structure of the carton is more stable.

The adhesive tape 2 is arranged on the inner surface of the upper cover plate 131, the inner surface of the upper cover plate 131 is also provided with a tearing strip 4, and the outer surface of the upper cover plate 131 is provided with a tearing line 14 at the edge corresponding to the tearing strip 4. Through setting up tear strip 4 and tear line 14, can convenience of customers unpack, as long as tear along tear line 14 when unpacking and draw and can unpack, the user need not use other unpacking tools.

The bottom plate 11 is adhered with a buffer pad 5 which can fix and protect the fragile object to be packed. The cushion 5 may be made of a flexible material, for example, the cushion 5 may be a sponge.

The overlapping area of the side plates forms a diamond-shaped dustproof wing 15, namely, four diamond-shaped dustproof wings 15 are arranged in total, and a crease 151 is arranged on a diagonal line of the diamond-shaped dustproof wing 15, which is intersected with the bottom plate 11. The dustproof wing is folded along crease 151 during carton shaping, forms stable triangle-shaped structure, and the triangle-shaped structure holds two adjacent curb plates inwards or outwards upset, has strengthened the intensity in carton four corners simultaneously. And four rhombus dustproof wings 15 integrated into one piece, dustproof effect and reinforcement effect are better.

The lower cover 132 is engaged with both the left cover 133 and the right cover 134. The left cover plate 133 and the right cover plate 134 are provided with clamping grooves 16, the lower cover plate 132 is provided with a rocking cover 17, and the hollow areas 3 are located on two sides of the rocking cover 17. The two ends of the rocking cover 17 are provided with a locking tongue 171, the locking tongue 171 is clamped with the clamping groove 16, namely the rocking cover 17 is simultaneously clamped with the left cover plate 133 and the right cover plate 134, the displacement of the lower cover plate 132 and the left and right cover plates 134 can be limited, and the left, right and rear side plates 122 are ensured to be vertical to the bottom plate 11.

The rocking cover 17 is provided with a folding line 172, and the rocking cover 17 can rotate relative to the lower cover plate 132 through the folding line 172 to drive the locking tongue 171 to rotate and be clamped in the clamping groove 16 backwards. The lower cover plate 132 extends forwards to form a convex strip 18, the rocking cover 17 is connected with the convex strip 18 through a folding line 172, and the locking tongues 171 are positioned on two sides of the convex strip 18 and behind the folding line 172. When the cover 17 is rotated backward, the latch 171 can be driven to rotate, and because the latch 171 is located behind the folding line 172, when the cover 17 is rotated backward, the latch 171 rotates forward and extends into the slot 16, and then the cover 17 is rotated forward, the latch 171 rotates backward and is engaged with the slot 16 backward. The clamping mode is very convenient to operate, quick clamping can be achieved through rotation of the rocking cover 17, the clamping effect is good, and the clamping can be separated only by rotating the rocking cover 17.

The convex strip 18 partially covers the left cover plate 133 and the right cover plate 134, so that the rocking cover 17 and the left and right cover plates 134 can be tightly clamped, the left and right cover plates 134 can support the convex strip 18, and the structural strength is better. Be equipped with the suture between spring bolt 171 and the sand grip 18, both can guarantee the normal rotation of spring bolt 171, make between spring bolt 171 and the sand grip 18 very compact again, not only make structural strength better, can block inseparabler moreover. The length of the card slot 16 is greater than that of the latch tongue 171 so that the latch tongue 171 can easily enter the card slot 16.

The assembly of this embodiment is made as follows:

removing waste materials from the paper board after die cutting to obtain a paper box body 1;

adhering the cushion pad 5 to the bottom plate 11;

the adhesive tape 2 and the tear tape 4 are adhered to the upper cover plate 131.

The application process of this embodiment is as follows:

the user places the packaged item on the bottom plate 11;

the user folds the upper, lower, left and right cover plates 134 inward, and at this time, the four dust-proof wings are folded inward along the creases 151;

the user pulls up the swing cover 17 on the lower cover plate 132 to engage the latch 171 with the slot 16;

the user sticks the adhesive tape 2 on the upper cover plate 131 to the cover plate and the swing cover 17.

The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all the equivalent technical changes using the description and drawings of the present invention are included in the scope of the present invention.
