Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 2, the present utility model is a two-sided concave packing box, which is formed by a bottom plate 10, and upright front, rear, left and right side plates 11, 12, 13, 14 connected to the peripheral edges of the bottom plate 10. The upper edges of the left side plate 13 and the right side plate 14 are connected with a folding plate 16.

As shown in fig. 1, 2 and 4, a locking structure for locking and fixing the four side plates is further included. The latch structure includes a first tab 25 connected to the upper left and right edges of the front side panel 11 and extending rearward, and a second tab 26 connected to the upper left and right edges of the rear side panel 12 and extending forward. A first slot 27 is provided at the rear of the first tab with a downward opening. A second slot 28 is provided in the front of the second tab 26 and is upwardly open to allow interlocking with the first slot. Therefore, the first insertion slot is inserted into the corresponding second insertion slot to form a mutual clamping structure, and the front side plate and the rear side plate are fixed. The lower parts of the left and right edges of the front side plate 11 are also connected with a first folding piece 20 attached to the inner surface of the front side plate. The lower parts of the left and right edges of the rear side plate 12 are also connected with second folding pieces 21 attached to the inner surface of the rear side plate. The first tab 20 and the second tab 21 are identical in structure. There is a groove 22 at the lower edge of all flaps. A pressing plate 23 is attached to the upper edge of each folding plate 16. The front and rear edges of the pressure plate 23 are each connected with an outwardly projecting tab 24. Wherein the distance between the outer edges of the two tabs 24 in the width direction is slightly larger than the distance between the front side plate 11 and the rear side plate 12. During assembly, the folding plate and the pressing plate are folded, and all the protruding sheets are inserted into the corresponding grooves, so that all the side plates are fixed. Therefore, when the front side plate and the rear side plate are fixed, the front side plate and the rear side plate can apply slight extrusion force to the two lug plates in the width direction, so that a locking structure is formed between the lug plates and the front side plate and the rear side plate, and meanwhile, all the lug plates are inserted into corresponding grooves to be clamped, so that a clamping groove type lock catch structure is formed, and the stability of the whole structure of the packing box is improved.

In this embodiment, as shown in fig. 5 and 7, both ends of the joint of the pressing plate 23 and the folding plate 16 are provided with notches 17. With this structure, the notch 17 can avoid the top wall of the corresponding groove when assembling and forming, thereby reducing resistance and making the locking process smoother.

As shown in fig. 1 and 2, in the present embodiment, the left side plate 13 and the right side plate 14 each have a first crease line 30 thereon. The two first crease lines 30 divide the left and right side panels 13 and 14 into a first adhesive sheet 151 and a barrier 152, respectively, which are adhered to the surface of the bottom panel 10. The appearance of the packaging box formed by folding the structure is more attractive.

As shown in fig. 2 and 4, in the present embodiment, the first tab 25 has a second crease line 31 thereon. The second crease line 31 divides the first tab 25 into a second adhesive sheet 251 and a first movable sheet 252 adhered to the inner surface of the front side panel 11. The second tab 26 has a third crease line 32 thereon. The third crease line 32 divides the second tab into a third adhesive sheet 261 and a second movable sheet 262 adhered to the inner surface of the rear side panel 12. Wherein the first adhesive sheet 151, the second adhesive sheet 251 and the third adhesive sheet 261 have the same width.

In this embodiment, the first tab 20 has a fourth crease line 33 thereon. The fourth crease line 33 divides the first flap 20 into a fourth adhesive sheet 201 and a third movable sheet 202 which are adhered to the inner surface of the front side panel 11. The second flap 21 has a fifth crease line 34 thereon. The fifth crease line 34 divides the second flap 21 into a fifth adhesive sheet 211 and a fourth movable sheet 212 which are adhered to the inner surface of the rear side panel 12.

A lid 9 for sealing the pack is attached to the upper edge of the rear side plate 12. The upper, left and right edges of the box cover 9 are connected with folding plates 8 adhered to the inner surface of the box cover 9. By adopting the structure, the whole packaging box is more stable and difficult to deform after being molded.

In the present utility model, three folding plates 8 are spliced to fill the inner side of the box cover 9. By adopting the structure, the section of the folding plate is invisible, so that the inside of the packaging box can be beautified.

The upper edge of the box cover 9 is connected with an inserting tongue 7. A wing 6 is connected to the upper edge of the front side plate 11. A socket 5 matched with the inserting tongue 7 is arranged at the joint of the wing plate 6 and the front side plate.

The packaging box is manufactured by pre-gluing corrugated paper boards through die cutting, V-shaped groove forming and box pasting equipment. When storage or transportation is needed, all the plates of the packaging box can be tiled to form a tiled state as shown in fig. 3, so that occupied space is saved, and storage and transportation are convenient. When needed, the left side plate and the right side plate are respectively turned up by 90 ° along the corresponding first crease lines 30, the two first inserting sheets 25 are respectively turned up by 90 ° along the corresponding second crease lines 31, and the two second inserting sheets 26 are respectively turned up by 90 ° along the corresponding third crease lines 32 in fig. 4. Thereafter, the front side plate 11 and the rear side plate 12 are folded upward as in fig. 1, and at the same time, the first insertion slits 27 are inserted into the corresponding second insertion slits 28. Folding plate 16 and pressing plate 23 are folded over as in fig. 5, and all tabs 24 are inserted into corresponding grooves 22. Then, as shown in fig. 6, the product is put into the packaging box, and then the box cover 9 and the wing plate 6 are turned over, and the inserting tongue 7 is inserted into the inserting opening 5, so that the operation is convenient.

In summary, according to the utility model, the first insertion slot is inserted into the corresponding second insertion slot to form the inter-locking structure, the front side plate and the rear side plate are fixed, and the distance between the outer edges of the two protruding sheets in the width direction is slightly larger than the distance between the front side plate and the rear side plate, so that the fixing of the front side plate and the rear side plate can apply slight extrusion force to the two protruding sheets in the width direction, thereby promoting the protruding sheets to form a locking structure with the front side plate and the rear side plate, and simultaneously, all the protruding sheets are inserted into the corresponding grooves to form the clamping groove type locking structure, so that the stability of the whole structure of the packaging box is improved.
