Description

Technical Field

[0001] The utility model relates to the field of packing boxes, in particular to a packing box convenient for transportation. Background Art

[0002] A packing box plays a very important role and has a certain degree of influence from product production to the entire sales process; the volume and weight of the packing box affect the cost-effectiveness of transportation and storage. Especially in retail stores and commercial buildings, the quality of the packing box affects the customer's first impression of the product to a certain extent. High-quality packaging will enhance the brand image of the enterprise; however, high-quality packing boxes often have a relatively large volume, which will occupy a large amount of space and position during transportation, increasing the transportation cost.

[0003] In the document with the patent publication number CN102171105A, a foldable packing box with an inner folding panel is disclosed, which includes a bottom part, an upper cover part edge and an inner folding panel part. The bottom part includes a bottom panel, opposite rear panels and front panels and opposite side panels, and the front panel, rear panel and side panel are connected to the bottom panel of the bottom part in a state where they can be folded up and lowered downwards. The upper cover part includes an upper cover panel; the inner folding panel part includes a rear panel, and the inner folding panel part and the upper cover part are respectively connected to the rear panel of the bottom part in a state where they can be folded up and lowered downwards; the inner folding rear panel of the inner folding panel part has a connecting surface connected to the rear panel of the bottom part, and when the two are connected, the inner folding rear panel of the inner folding panel part and the rear panel of the bottom part will be in face-to-face contact. In such a case, the rear panel of the inner folding panel part just provides internal supporting force for the rear panel of the bottom part of the formed packing box, and plays a more consolidating role; the bottom part is folded up to form a basic box body, the inner folding part is folded towards the inside of the box body and fits with the surrounding of the inside of the box body, and the upper cover part forms a cover body, so that the box body forms a closed space.

[0004] However, since its inner folding part is folded towards the inside of the box body, the space inside the box body is reduced, that is, the volume of the packing box is reduced, which means that the products packed are reduced under the same transportation cost, or the production cost needs to be increased when customizing the packing of specified products.

[0026] As Figures 1 to 5 shown, a packaging box convenient for transportation includes an outer box 1 and an inner box 2. The inner box 2 is detachably arranged inside the outer box 1; the outer box 1 has a bottom plate 11. The front edge of the bottom plate 11 is connected with a front plate 12, the rear edge 0 of the bottom plate 11 is connected with a rear plate 13, one end of the rear plate 13 opposite to the bottom plate 11 is connected with a cover plate 14, and one end of the cover plate 14 opposite to the rear plate 13 is connected with a front cover plate 141.

[0027] On the left and right sides of the bottom plate 11, side plates 15 are respectively connected. The front and rear ends of the side plates 15 have first creases 151, and folding connection parts 16 are formed through the first creases. The folding connection parts 16 include first connection parts 161 and second connection parts 162. The outer sides of the first connection parts 161 are respectively fixedly connected to the front plate 12 and the rear plate 13. There is a second crease 163 between the first connection parts 161 and the second connection parts 162. Through the first crease 151 and the second crease, the outer box 1 can freely switch between the folded state and the lowered state.

[0028] Wherein, an adhesive part 164 is arranged on the outer side of the second connection part 162. When the outer box 1 is in the lowered state, the inner side surface of the second connection part 162 fits with the inner side surface of the first connection part 161, and the adhesive part 164 on the outer side surface of the second connection part 162 adheres to a lining paper, so that it will not be adhered together randomly during transportation; when the outer box 1 needs to be folded, at this time, the lining paper on the adhesive part 164 is torn off, so that the adhesive part 164 on the outer side surface of the second connection part 162 respectively fits with the inner side surfaces of the front plate 12 and the rear plate 13.

[0029] Two metal sheets 142 are symmetrically arranged in the front cover plate 141. A magnetic part 121 is arranged at a position corresponding to the metal sheet 142 in the front plate 12. When the front cover plate 141 covers the front plate 12, the magnetic part 121 adsorbs the metal sheet 142, so that the front cover plate 141 is firmly attached to the front plate 12. At the same time, the cover plate 14 is connected to the front cover plate 141, which also enables the cover plate 14 to be firmly covered on the outer box 1 to form a closed space; at the same time, a handle part can be arranged at one end of the front cover plate 141 opposite to the cover plate, so that the user can easily separate the front cover plate 141 from the front plate 12.

[0030] As Figures 3 to 4 shown, the inner box includes a bottom inner plate 21. First grooves 212 are respectively arranged around the bottom inner plate 21. First protrusions 213 are arranged at the bottoms of the front inner plate 22, the rear inner plate 23 and the side inner plates 24. By inserting the first protrusions 213 into the first grooves 0, the front end of the bottom inner plate 21 is detachably connected to the front inner plate 22, the rear end of the bottom inner plate 21 is detachably connected to the rear inner plate 23, and the left and right sides of the bottom inner plate 21 are respectively detachably connected to the side inner plates 24; at the same time, second grooves 241 are arranged on the left and right sides of the rear of the front inner plate 22, and second protrusions 242 are arranged on the left and right sides of the side inner plates 24. The second grooves 241 can be inserted into the second protrusions 242, so that the front inner plate 22 and the rear inner plate 23 are detachably connected to the side inner plates 24; that is, any two of the bottom inner plate 21, the front inner plate 22, the rear inner plate 23 and the two side inner plates are detachably connected.

[0031] In this embodiment, a spacer 25 is provided in the inner box 2. Third protrusions 251 are provided at the bottom, front and rear sides of the spacer 25. Third grooves 252 are provided on the surfaces of the bottom inner plate 21 and the side inner plates 24. The third protrusions 251 can be inserted into the third grooves 252. The inner box 2 is divided into two independent placement spaces by the spacer 25, enabling the user to place items separately according to the characteristics of the items to be placed. If partitioned placement is not required, the spacer 25 can be removed without affecting the use of the packaging box.

[0032] In this embodiment, the front inner plate 22, the rear inner plate 23, the bottom inner plate 21, the side inner plates 24 and the spacer 25 in the inner box 2 are all made of foaming material and have a certain thickness, which enables the packaging box to better protect some fragile items when placing them. At the same time, a buffer plate 143 is provided on the inner side surface of the cover plate 14, and the size of the buffer plate 143 is smaller than that of the cover plate 14. Flocking operations are performed on the inner side surfaces of the inner plates and the buffer plate 143 to further prevent the items in the box from being scratched. When the cover plate 14 is closed, the outer periphery of the buffer plate 143 on the inner side of the cover plate 14 is all placed on the upper edge of the inner plate of the inner box 2, enabling the inner box 2 to better protect the items inside the box.

[0033] In this embodiment, an inner upper cover 243 is connected to the outer side surface of the side inner plate 24. The size of the inner upper cover 243 is slightly larger than the cross-sectional size of the inner spaced placement space. When placing items separately in the packaging box, a certain space can be additionally enclosed. In another embodiment, the inner upper cover 243 can also be connected to the spacer 25 or the inner side surface of the side inner plate 24. At the same time, the inner upper cover 243 can be folded towards the inside of the box to additionally enclose a certain space.
