[0026] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Packaging box 1 is used to package items, such as Figure 1 and Figure 2 As shown, the packaging box 1 includes a left pull box 2, a right pull box 3, and an inner tray 4. After being formed, the left pull box 2 and the right pull box 3 can form a first receiving cavity 5. The inner tray 4 is installed in the first receiving cavity 5 and is used to carry the packaged items. Taking the packaging box 1 placed on a horizontal plane as a reference, the height direction of the packaging box 1 is the up and down direction. The term "formed" can be understood as the left pull box 2, the right pull box 3, or the inner tray 4 having formed a receiving space that can accommodate items. After the packaging box 1 is formed, at least a part of one of the left pull box 2 and the right pull box 3 is accommodated by the other. This utility model mainly uses the example of at least a part of the right pull box 3 being accommodated by the left pull box 2 for illustration.

[0028] like Figure 3 and Figure 6As shown, the left pull box 2 includes a first bottom plate 21, a first side plate 22, a first top plate 23, a second side plate 24, and a third side plate 25. The first bottom plate 21, the first side plate 22, the first top plate 23, the second side plate 24, and the third side plate 25 can be enclosed to form a first cavity 213 with a first opening 212. The opening direction of the first opening 212 is parallel to the movement direction of the left pull box 2 / right pull box 3. After the left pull box 2 is formed, the first bottom plate 21 and the first top plate 23 are opposite to each other, the first side plate 22 and the second side plate 24 are opposite to each other, and the third side plate 25 is opposite to the first opening 212.

[0029] The first top plate 23 is provided with at least a first notch 232 for allowing the packaged item to be exposed / displayed. When the left pull box 2 is formed, the opening direction of the first notch 232 intersects with the opening direction of the first opening 212. In some preferred embodiments, the first notch 232 and the first opening 212 are interconnected.

[0030] The phrase "packaged items are exposed / displayed" means that the packaged items can be directly taken out by the user with their hands or tools, while "packaged items are not exposed / displayed" means that the packaged items cannot be directly taken out by the user with their hands or tools.

[0031] In some embodiments, the first notch 232 is formed in an arc shape.

[0032] In some embodiments, the first notch 232 can also be used to place a user's finger, making it easier for the user to open the packaging box 1.

[0033] The first base plate 21 is provided with a second notch 211 opposite to the first notch 232. The second notch 211 is used to place the user's finger so that the user can pull his finger when closing and opening the packaging box 1.

[0034] In some preferred embodiments, the second notch 211 is also in communication with the first opening 212.

[0035] The left pull box 2 is also provided with a first connecting hole 231. The inner tray 4 is connected to the left pull box 2 through the first connecting hole 231. The first connecting hole 231 is provided on the first top plate 23 or the third side plate 25.

[0036] like Figure 4 and Figure 7As shown, the right pull box 3 includes a second bottom plate 31, a fourth side plate 32, a second top plate 33, a fifth side plate 34, and a sixth side plate 35. The second bottom plate 31, the fourth side plate 32, the second top plate 33, the fifth side plate 34, and the sixth side plate 35 can be enclosed to form a second cavity 312 with a second opening 311. The opening direction of the second opening 311 is parallel to the movement direction of the left pull box 2 / right pull box 3. After the right pull box 3 is formed, the second bottom plate 31 and the second top plate 33 are opposite to each other, the fourth side plate 32 and the fifth side plate 34 are opposite to each other, and the sixth side plate 35 is opposite to the second opening 311. The inner tray 4 is connected to the left pull box 2 and the right pull box 3 respectively, and at least a part of the inner tray 4 is located between the third side plate 25 and the sixth side plate. The inner tray 4 is connected to the second top plate 33 or the sixth side plate 35. At the same time, the inner tray 4 is also connected to the first top plate 23 or the third side plate 25.

[0037] In the vertical direction, at least one of the first base plate 21 and the second base plate 31 forms the base plate of the packaging box 1.

[0038] A third notch 332 is provided on the second top plate 33. The opening direction of the third notch 332 intersects with the opening direction of the second opening 311. In some preferred embodiments, the third notch 33 and the second opening 311 are interconnected. Through the cooperation between the first notch 232 and the third notch 332, the packaged item can be exposed.

[0039] In some embodiments, the third notch 332 is formed in an arc shape.

[0040] The right pull box 3 is also provided with a second connecting hole 331. The inner tray 4 is connected to the right pull box 3 through the second connecting hole 331. The second connecting hole 331 is provided on the second top plate 33 or the sixth side plate 35.

[0041] When the packaging box 1 is closed and the right pull box 3 is accommodated by the left pull box 2, the first accommodating cavity 5 includes a part of the first cavity 213 and the entirety of the second cavity 312; or, when the packaging box 1 is closed and the left pull box 2 is accommodated by the right pull box 3, the first accommodating cavity 5 includes a part of the second cavity 312 and the entirety of the first cavity 213.

[0042] like Figure 5 and Figure 8As shown, the inner support 4 includes a third base plate 41, a support member 42, a connector 43, and a reinforcing member. The third base plate 41 is connected to the support member 42, and the support member 42 is connected to the connector 43. The third base plate 41, the support member 42, the reinforcing member, and the connector 43 are integrally formed. The connector 43 includes a first connecting part 431 and a second connecting part 432. The first connecting part 431 and the second connecting part 432 are located on both sides of the support member 42. The first connecting part 431 can pass through the second connecting hole 331 and connect to the right pull box 3. The second connecting part 432 can pass through the first connecting hole 231 and connect to the left pull box 2.

[0043] In some embodiments, the first connecting portion 431 and the second connecting portion 432 are symmetrically arranged with respect to the carrier member 42.

[0044] In some embodiments, the first connecting portion 431 and the second connecting portion 432 have the same structure.

[0045] After the inner tray 4 is formed, a second receiving cavity 44 can be formed between the carrier 42 and the third base plate 41. The second receiving cavity 44 is used to receive and fix a part of the packaged item. The carrier 42 includes a main body 422 and a squeezed part 421. The squeezed part 421 can move relative to the main body 422. The squeezed part 421 can make the packaged item stably fixed in the second receiving cavity 44. In addition, the squeezed part 421 can also make the second receiving cavity 44 able to receive and fix packaged items of different sizes and shapes, thereby broadening the application range of the packaging box 1. In some embodiments, the squeezed part 421 is set as a serrated shape.

[0046] The first connecting part 431 includes a first lifting part 433, a first bending part 434 and a first fixing part 435 connected in sequence. The first lifting part 433 is connected to the carrier 42. The first fixing part 435 can pass through the second connecting hole 331 and be fixed on the second top plate 33 or the sixth side plate 35, so that the inner tray 4 and the right pull box 3 are combined with each other. The first fixing part 435 can be fixed on the right pull box 3 by means of adhesive, snap-fit, fastening and magnetic connection.

[0047] The first fixing part 435 is fixed to the second top plate 33 or the sixth side plate 35. When the right pull box 3 is subjected to an external force and moves away from the left pull box 2, the force is transmitted through the right pull box 3 to the first fixing part 435, and then through the first fixing part 435 to the first lifting part 433. Since the first lifting part 433 and the first fixing part 435 are formed as a whole, as the right pull box 3 moves, the first lifting part 433 is driven upward by the first fixing part 435. During the movement, the first fixing part 435 will not be subjected to a force opposite to the direction of movement of the right pull box 3. Therefore, the first fixing part 435 will not have a tendency to detach from the right pull box 3. The inner tray 4 can maintain a stable connection with the right pull box 3, which improves the stability of the inner tray 4 in the packaging box 1 and further reduces the possibility of the packaged item falling off during the movement.

[0048] In some preferred embodiments, the first fixing part 435 is fixed to the sixth side plate 35. When the right pull box 3 is subjected to an external force and moves away from the left pull box 2, the first fixing part 435 will be subjected to a force in the same direction as the movement of the right pull box 3. Under the action of the force, the connection between the first fixing part 435 and the sixth side plate 35 will become tighter, further ensuring that the first fixing part 435 will not detach from the right pull box 3.

[0049] In some embodiments, the first bending portion 434 can also pass through the second connecting hole 331. After the packaging box 1 is formed, at least a portion of the first bending portion 434 overlaps with the second top plate 33 in the vertical direction. In this configuration, the first lifting portion 433 is more easily driven to move by the first fixing portion 435.

[0050] Correspondingly, the second connecting part 432 also has a second lifting part 437, a second bending part 438, and a second fixing part 439. The first lifting part 433 has the same structure as the second lifting part 437, the first bending part 434 has the same structure as the second bending part 438, and the first fixing part 435 has the same structure as the second fixing part 439.

[0051] The second fixing part 439 can pass through the first connecting hole 231 and be fixed on the first top plate 23 or the third side plate 25. When the left pull box 2 is subjected to external force and moves away from the right pull box 3, the movement process of the second lifting part 437 is the same as the movement process of the first lifting part 433 when the right pull box 3 is subjected to external force and moves away from the left pull box 2, except that the movement direction of the second fixing part 439 is opposite to the movement direction of the first fixing part 435.

[0052] In some embodiments, the second bend 438 can also pass through the first connecting hole 231.

[0053] In some embodiments, the third base plate 41 can also be connected to at least one of the first lifting part 433 and the second lifting part 437.

[0054] In some embodiments, after the packaging box 1 is formed, in the first receiving cavity 5, the first fixing part 435 is directly fixedly connected to the second top plate 33 or the sixth side plate 35, and the second fixing part 437 is directly fixedly connected to the first top plate 23 or the third side plate 25.

[0055] When the packaging box 1 is closed, the packaged item cannot be taken out, or the packaged item cannot be exposed / displayed. At this time, the packaging box 1 is in the closed state, and the plane where the first lifting part 433 is located is not in the same plane as the plane where the carrier 42 is located. When the packaging box 1 is open, or the packaged item is exposed / displayed and can be taken out, the packaging box 1 is in the open state, and the plane where the first lifting part 433 is located is not perpendicular to the plane where the carrier 42 is located. The packaging box 1 can switch between the open state and the closed state.

[0056] The inner tray 4 can switch between a retracted state and a raised state. When the packaging box 1 is in the open state, the inner tray 4 is in the raised state, and the packaged item can be exposed / displayed. When the packaging box 1 is in the closed state, the inner tray 4 is in the retracted state, and the packaged item cannot be exposed / displayed. At least a portion of the inner tray 4 in the raised state is further away from the bottom plate of the packaging box 1 than that portion of the inner tray 4 in the retracted state.

[0057] The reinforcing member includes at least one of a first reinforcing plate 436 and a second reinforcing plate 480. The first reinforcing plate 436 and the second reinforcing plate 480 are respectively located on both sides of the support member 42. The end of the first reinforcing plate 436 away from the support member 42 and the end of the second reinforcing plate 480 away from the support member 42 are both movably disposed relative to the support member 42. Specifically, one end of the first reinforcing plate 436 is connected to the first connecting part 431 / first lifting part 433, and the other parts of the first reinforcing plate 436 are not connected to the first connecting part 431 / first lifting part 433. The second reinforcing plate 480 is connected to the second connecting part 432 / second lifting part 437, and the other parts of the second reinforcing plate 480 are not connected to the second connecting part 432 / second lifting part 437.

[0058] When the inner tray 4 is in the raised state, the first reinforcing plate 436 is out of contact with the right pull box 3, and the second reinforcing plate 480 is out of contact with the left pull box 2. The plane where the first reinforcing plate 436 is located is not perpendicular to the plane where the first lifting part 433 is located, and the plane where the second reinforcing plate 480 is located is not perpendicular to the plane where the second lifting part 437 is located. When the inner tray 4 is in the retracted state, the first reinforcing plate 436 abuts against the right pull box 3 / sixth side plate 35, and the second reinforcing plate 480 abuts against the left pull box 2 / third side plate 25. Under the combined action of the first reinforcing plate 436 and the second reinforcing plate 480, the deformation or movement of the bearing member 42 can be prevented, the stability of the inner tray 4 is increased, and the shaking of the inner tray 4 is avoided, which would affect the stability of the packaged items and further ensure that the packaged items are not damaged.

[0059] When the packaging box 1 is in the closed state, at least one of the following will form a gap space: between the first lifting part 433 and the sixth side plate 35, and between the second lifting part 437 and the third side plate 25. The smaller the gap space, the more stable the inner tray 4 / reinforcing member is in the packaging box 1. In other words, the smaller the distance between the first reinforcing plate 436 and the sixth side plate 35, and / or the smaller the distance between the second reinforcing plate 480 and the third side plate 235, the more stable the inner tray 4 is in the packaging box 1, and the less likely the packaged items are to be damaged.

[0060] In some preferred embodiments, when the inner support 4 is in a retracted state, the plane where the first reinforcing plate 436 is located is perpendicular to the plane where the first lifting part 433 is located, and the plane where the second reinforcing plate 480 is located is perpendicular to the plane where the second lifting part 437 is located.

[0061] In some preferred embodiments, the end of the first reinforcing plate 436 connected to the first connecting portion 431 / first lifting portion 433 is located at the connection between the first lifting portion 433 and the carrier member 42, and / or, the end of the second reinforcing plate 480 connected to the second connecting portion 432 / second lifting portion 437 is located at the connection between the second lifting portion 437 and the carrier member 42.

[0062] In some preferred embodiments, the extension direction of the end of the first reinforcing plate 436 that abuts against the sixth side plate 35 of the right pull box 3 is parallel to the sixth side plate 35, and / or, the extension direction of the end of the second reinforcing plate 480 that abuts against the third side plate 35 of the left pull box 2 is parallel to the third side plate 35.

[0063] In some preferred embodiments, when the packaging box 1 is in the open state, at least one of the first reinforcing plate 436 and the second reinforcing plate 480 is flush with the connector 43 in the vertical direction.

[0064] As described above, during the movement of the inner tray 4 from the retracted state to the raised state, at least one of the left pull box 2 and the right pull box 3 can stably transmit force to the inner tray 4, thereby further preventing the load-bearing component 42 from deforming or moving and preventing damage to the packaged items.

[0065] When the packaging box 1 is opened, the packaged items are exposed / displayed through the exposure opening formed by the first notch 232 and the third notch 332.

[0066] In some preferred embodiments, when the packaging box 1 is in the open state, the first lifting part 433, the second lifting part 437 and the carrier 42 are located in the same plane.

[0067] When the right pull box 3 is pulled away from the left pull box 2, the first fixing part 435 moves away from the left pull box 2 along with the right pull box 3. The first lifting part 433 is driven by the first fixing part 435 to move away from the left pull box 2. Then, the first connecting part 431 drives the second connecting part 432 to move upward. The inner tray 4 moves from the retracted state to the lifted state. The packaging box 1 changes from the closed state to the open state, and the packaged item is exposed / displayed through the exposure opening.

[0068] When the left pull box 2 is pulled away from the right pull box 3, the second fixing part 439 moves away from the right pull box 3 along with the left pull box 2. The second lifting part 437 is driven by the second fixing part 439 to move away from the right pull box 3. Then, the second connecting part 432 drives the first connecting part 431 to move upward. The inner tray 4 moves from the retracted state to the lifted state. The packaging box 1 changes from the closed state to the open state. The packaged item is exposed / displayed through the exposure opening.

[0069] When the left pull box 2 is pulled away from the right pull box 3 and the right pull box 3 is pulled away from the left pull box 2 at the same time, as the left pull box 2 and the right pull box 3 move simultaneously, the second lifting part 437 is driven by the second fixing part 439 to move away from the right pull box 3, and the first lifting part 433 is driven by the first fixing part 435 to move away from the left pull box 2. The first lifting part 433 and the second lifting part 437 simultaneously drive the carrier 42 to move upward, the inner tray 4 moves from the retracted state to the lifted state, the packaging box 1 changes from the closed state to the open state, and the packaged item is exposed / displayed through the exposure opening.

[0070] During the process of the packaging box 1 changing from the closed state to the open state, the packaged item is fixed by the carrier 42, the first reinforcing plate 436 is disengaged from the sixth side plate 35, and the second reinforcing plate 480 is disengaged from the third side plate 25.

[0071] When the right pull box 3 is pushed toward the left pull box 2, and / or when the left pull box 2 is pushed toward the right pull box 3, the inner tray 4 / support member 42 moves downward under its own gravity as the right pull box 3 and / or the left pull box 2 move. The first fixing part 435 and the second fixing part 439 are both driven downward by the support member 42. The inner tray 4 moves from the raised state to the retracted state, and the packaging box 1 changes from the open state to the closed state.

[0072] During the process of the packaging box 1 changing from the open state to the closed state, the first opening 212 and the second opening 311 are gradually closed.

[0073] [Beneficial Effects]

[0074] Compared with the prior art, the packaging box 1 provided by this utility model has the following beneficial effects:

[0075] Firstly, during the process of the packaging box 1 changing from a closed state to an open state, at least one of the left pull box 2 and the right pull box 3 can move away from each other. The first fixing part 435 can drive the first lifting part 433 to move upward together. Then, the first lifting part 433 drives the carrier 42 to move upward, and the carrier 42 drives the second lifting part 437 to move. Alternatively, the second fixing part 437 can drive the second lifting part 437 to move upward together. Then, the second lifting part 437 drives the carrier 42 to move upward, and the carrier 42 drives the first lifting part 433 to move. Alternatively, the first fixing part 435 drives the first lifting part 433 to move upward while the second fixing part 437 drives the second lifting part 437 to move upward. The first lifting part 433 and the second lifting part 437 simultaneously drive the carrier 42 to move upward. The inner tray 4 moves from a retracted state to a lifted state, and the packaged item is lifted along with the inner tray 4. This makes it convenient for people to take out the packaged item and also has a better display effect.

[0076] Secondly, the inner tray 4 of the packaging box 1 includes a third base plate 41 and a support member 42 that are connected to each other. After the inner tray 4 is formed, a second receiving cavity 44 can be formed between the support member 42 and the third base plate 41, and at least a part of the packaged item can be received by the second receiving cavity 44.

[0077] The carrier 42 also has a compression part 421 that can move relative to the main body 422. When the packaged item is placed on the inner tray 4, the compression part 421 can compress the packaged item, so that the packaged item is more stably fixed.

[0078] Thirdly, according to the description in the second aspect, the arrangement of the squeezed part 421 also enables the second receiving cavity 44 to accommodate and fix packaged items of different sizes and shapes, thus broadening the application range of the packaging box 1.

[0079] Fourthly, according to the first aspect, the first fixing part 435 can be fixed to the outer surface of the sixth side plate 35 of the right pull box 3, and the second fixing part 439 can be fixed to the outer surface of the third side plate 25 of the left pull box 2. With this configuration, during the process of the packaging box 1 changing from the closed state to the open state, the first fixing part 435 will not be subjected to a force opposite to the direction of movement of the right pull box 3. Therefore, the first fixing part 435 will not have a tendency to move away from the right pull box 3. Alternatively, the second fixing part 437 will not be subjected to a force opposite to the direction of movement of the left pull box 2. The second fixing part 437 will not have a tendency to move away from the left pull box 2. This strengthens the connection between the inner tray 4 and the left pull box 2 and the right pull box 3, improves the stability of the inner tray 4 in the packaging box 1, and further reduces the possibility of the packaged item falling off during the movement.

[0080] Fifthly, the first connecting part 431 and the second connecting part 432 of the inner tray 4 are respectively provided with a first reinforcing plate 436 and a second reinforcing plate 480. When the packaging box 1 is in the closed state, the first reinforcing plate 436 can abut against the sixth side plate 35, and the second reinforcing plate 480 can abut against the third side plate 25. This can also enhance the stability of the inner tray 4 and prevent the inner tray 4 from shaking or moving.
