Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a stackable foam packaging box. Background Art

[0002] With the rise of e-commerce, foam packaging boxes are increasingly being used in the logistics industry. As a lightweight, heat-insulating and shock-proof packaging material, foam packaging boxes play an irreplaceable role in protecting product safety and reducing transportation losses.

[0003] Application No. 202021809072.8 discloses a foam packaging box. By arranging an airbag on the right side of the movable plate, the purpose of squeezing and fixing the items in the installation groove by the airbag driving the movable plate is achieved, thereby facilitating the removal of the items in the installation groove. By arranging multiple observation windows on the top of the top cover, the purpose of observing the items in the installation groove is achieved.

[0004] The surface of the bottom box and the box cover of the above application is relatively smooth, and they are easy to collapse when stacked. The foam boxes made of polyethylene and polypropylene have low hardness, weak physical strength and are fragile, which greatly reduces the protective effect of the packaging. In addition, the inner panel is not easy to remove from the bottom box due to friction. Utility Model Content

[0006] To achieve the above purpose, the utility model is implemented through the following technical scheme: a stackable foam packaging box, including a box body, a storage cavity is opened inside the box body, a box cover is inserted into the top of the box body, fixed blocks are installed on the two corresponding sides of the bottom of the box body, and fixed grooves matching with the fixed blocks are opened on the two corresponding sides of the top of the box cover, a plurality of placement plates are placed inside the storage cavity, and a plurality of placement plates have placement grooves opened inside, the surfaces of the box body and the box cover are provided with FEP protective films, a limiting groove is opened at the bottom of the box body, and a limiting plate is inserted inside the limiting groove.

[0007] Preferably, magnetic metal sheets are installed on both corresponding sides of the top of the box body.

[0008] Preferably, magnet sheets are installed on two corresponding sides of the bottom of the box cover, and the magnet sheets are aligned with the magnetic metal sheets.

[0009] Preferably, the outer side of the limiting plate is wrapped with a sealing strip.

[0010] Preferably, grooves are formed on two corresponding sides of the box body.

[0011] Preferably, the structures of the limiting plate and the limiting groove are both T-shaped.

[0012] Preferably, invisible grooves are provided on the tops of the plurality of placement plates and on both sides corresponding to the placement grooves.

[0013] The utility model provides a stackable foam packaging box, which has the following beneficial effects:

[0014] 1. The stackable foam packaging box has fixing blocks and fixing grooves respectively arranged at the bottom of the box body and the top of the box cover, so that the packaging boxes can be plugged in and stacked more stably. The FEP protective film on the outside of the box body and the box cover can protect the surface of the packaging box, making it less susceptible to damage and breakage by external forces. At the same time, a limiting plate is inserted at the bottom of the box body, and the placement plate in the box body can be pushed upward by the limiting plate, so that the placement plate is easy to take out.

[0015] 2. The stackable foam packaging box has magnetic metal sheets and magnet sheets installed on the top of the box body and the bottom of the box cover respectively, so that the box body and the box cover are adsorbed together, which is beneficial to improve the stability between the box body and the box cover and make it difficult to fall off. The outer side of the limiting plate is wrapped with a sealing strip, which is beneficial to strengthen the tightness between the limiting plate and the limiting groove, and ensure the sealing of the packaging box.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figures 1 to 4The utility model provides a technical solution: a stackable foam packaging box, comprising a box body 1, a storage cavity 2 is opened inside the box body 1, a box cover 3 is plugged into the top of the box body 1, magnetic metal sheets 10 are installed on the two corresponding sides of the top of the box body 1, and magnet sheets 11 are installed on the two corresponding sides of the bottom of the box cover 3. The magnet sheets 11 are aligned with the magnetic metal sheets 10, and the adsorption between the magnet sheets 11 and the magnetic metal sheets 10 makes the fixation between the box body 1 and the box cover 3 more stable and not easy to separate, fixing blocks 12 are installed on the two corresponding sides of the bottom of the box body 1, and fixing grooves 13 matched with the fixing blocks 12 are opened on the two corresponding sides of the top of the box cover 3. The plug-in structure is convenient for stacking multiple packaging boxes, a plurality of placement plates 5 are placed inside the storage cavity 2, and placement grooves 6 are opened inside the plurality of placement plates 5. The corresponding two sides are provided with grooves 4 to facilitate the holding of the box body 1. Invisible grooves 15 are provided on the tops of the multiple placement plates 5 and on the two sides corresponding to the placement grooves 6 to facilitate the placement of the placement plates 5. The surfaces of the box body 1 and the box cover 3 are provided with FEP protective films 7, which have the advantages of high transparency and high temperature resistance, and protect the surface of the packaging box so that it is not easily damaged or broken by external forces. A limiting groove 8 is provided at the bottom of the box body 1, and a limiting plate 9 is inserted inside the limiting groove 8 to facilitate lifting the limiting plate 9 upward from the outside and pushing the placement plate 5 out of the storage cavity 2 to facilitate the removal of the placement plate 5. The outer side of the limiting plate 9 is wrapped with a sealing strip 14, which is beneficial to increase the tightness between the limiting plate 9 and the limiting groove 8 and the sealing of the box body 1. The structures of the limiting plate 9 and the limiting groove 8 are both T-shaped, so that the limiting plate 9 will not fall out of the limiting groove 8.

[0023] In summary, when the stackable foam packaging box is used, after placing the goods in the placement groove 6 of the placement plate 5, the required number of placement plates 5 can be placed in the storage cavity 2 in the box body 1 in sequence according to needs, and then the box cover 3 is covered on the top of the box body 1 to close the storage cavity 2. At the same time, the magnetic sheet 11 at the bottom of the box cover 3 is adsorbed together with the magnetic metal sheet 10 on the top of the box body 1 to fix the box body 1 and the box cover 3 to complete the packaging of the goods. When the packaging boxes need to be stacked, the fixing blocks 12 and the fixing grooves 13 respectively arranged at the bottom of the box body 1 and the top of the box cover 3 are used to stack multiple packaging boxes up and down, and the fixing blocks 12 under the upper packaging are inserted into the fixing grooves 13 on the lower packaging box to connect the packaging boxes. When the placement plate 5 in the storage cavity 2 needs to be taken out, the limiting plate 9 at the bottom of the box body 1 can be moved upward to the top and detached from the limiting groove 8. Under the action of the limiting plate 9, the placement plate 5 rises upward and is taken out of the storage cavity 2.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
