[0026] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0027] The packaging box 1 is used for packaging items, such as Figure 1 and Figure 2As shown, the packaging box 1 includes a left pull box 2, a right pull box 3 and an inner tray 4. After the left pull box 2 and the right pull box 3 are formed, they can form a first accommodation cavity 5. The inner tray 4 is installed in the first accommodation cavity 5 and is used to carry the item to be packaged. Taking the posture of 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 "formed" can be understood as an accommodation space capable of accommodating items has been formed in the left pull box 2, the right pull box 3 or the inner tray 4. 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. In the present invention, the case where at least a part of the right pull box 3 is accommodated by the left pull box 2 is mainly taken as an example for description.

[0028] As Figure 3 and Figure 6 As 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 enclose to form a first cavity 213 having 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] At least a first notch portion 232 for allowing the item to be packaged to be exposed / displayed is provided on the first top plate 23. When the left pull box 2 is formed, the opening direction of the first notch portion 232 intersects with the opening direction of the first opening 212. In some preferred embodiments, the first notch portion 232 communicates with the first opening 212.

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

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

[0032] In some embodiments, the first notch portion 232 can also be used for placing the user's fingers to facilitate the user to open the packaging box 1.

[0033] A second notch portion 211 opposite to the first notch portion 232 is provided on the first bottom plate 21. The second notch portion 211 is used for placing the user's fingers to facilitate the user to twitch the fingers when closing and opening the packaging box 1.

[0034] In some preferred embodiments, the second notch portion 211 also communicates with the first opening 212.

[0035] The left pull box 2 is further provided with a first connection hole 231, and the inner tray 4 is combined with the left pull box 2 through the first connection hole 231. The first connection hole 231 is arranged on the first top plate 23 or the third side plate 25.

[0036] As Figure 4 and Figure 7 As 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 enclose to form a second cavity 312 with a second opening 311. The opening direction of the second opening 311 is parallel to the moving 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 respectively connected to the left pull box 2 and the right pull box 3, 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 up and down direction, at least one of the first bottom plate 21 and the second bottom plate 31 forms the bottom plate of the packaging box 1.

[0038] A third notch 332 is arranged 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 communicates with the second opening 311. Through the mutual cooperation between the first notch 232 and the third notch 332, the article to be packaged can be exposed.

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

[0040] The right pull box 3 is further provided with a second connection hole 331, and the inner tray 4 is combined with the right pull box 3 through the second connection hole 331. The second connection hole 331 is arranged 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 accommodation cavity 5 includes a part of the first cavity 213 and the whole 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 accommodation cavity 5 includes a part of the second cavity 312 and the whole of the first cavity 213.

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

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

[0045] After the inner support 4 is formed, a second accommodation cavity 44 can be formed between the carrier 42 and the third base plate 41. The second accommodation cavity 44 is used to accommodate and fix a part of the item to be packaged. The carrier 42 includes a main body 422 and a squeezed portion 421. The squeezed portion 421 can move relative to the main body 422. The squeezed portion 421 can stably fix the item to be packaged in the second accommodation cavity 44. In addition, the arrangement of the squeezed portion 421 can also enable the second accommodation cavity 44 to accommodate and fix items to be packaged with different sizes and different shapes, thereby widening the application range of the packaging box 1. In some embodiments, the squeezed portion 421 is provided in a serrated shape.

[0046] The first connecting portion 431 includes a first lifting portion 433, a first bending portion 434, and a first fixing portion 435 that are connected in sequence. The first lifting portion 433 is connected to the carrier 42. The first fixing portion 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 support 4 is combined with the right pull box 3. The first fixing portion 435 can be fixed on the right pull box 3 by means such as adhesion, snap connection, stapling, and magnetic connection.

[0047] The first fixing part 435 is fixed on 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 in a direction away from the left pull box 2, the force is transmitted from the right pull box 3 to the first fixing part 435, and then from the first fixing part 435 to the first lifting part 433. Since the first lifting part 433 and the first fixing part 435 are integrally formed, as the right pull box 3 moves, the first lifting part 433 is driven by the first fixing part 435 to move upward; during the movement, the first fixing part 435 will not be subjected to a force in the direction opposite to the movement direction of the right pull box 3. Therefore, the first fixing part 435 will not have a tendency to break away from the right pull box 3, and the inner tray 4 can be stably connected to the right pull box 3, improving the stability of the inner tray 4 in the packaging box 1 and further reducing the possibility of the packaged items falling during the movement.

[0048] In some preferred embodiments, the first fixing part 435 is fixed on the sixth side plate 35. During the process that the right pull box 3 is subjected to an external force and moves in a direction 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 direction of the right pull box 3. Under the action of this 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 break away from the right pull box 3.

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

[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 and the second lifting part 437 have the same structure, the first bending part 434 and the second bending part 438 have the same structure, and the first fixing part 435 and the second fixing part 439 have the same structure.

[0051] The second fixing part 439 can pass through the first connection 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 an external force and moves in a direction 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 an external force and moves in a direction away from the left pull box 2 above, 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 bending part 438 can also pass through the first connection hole 231.

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

[0054] In some embodiments, after the packaging box 1 is formed, in the first accommodating cavity 5, the first fixing portion 435 is directly fixedly connected to the second top plate 33 or the sixth side plate 35, and the second fixing portion 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 and 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 portion 433 is located is not in the same plane as the plane where the carrier 42 is located; when the packaging box 1 is opened, or the packaged item is exposed / displayed, and the packaged item can be taken out, at this time, the packaging box 1 is in the open state, and the plane where the first lifting portion 433 is located is not perpendicular to the plane where the carrier 42 is located; the packaging box 1 can be switched between the open state and the closed state.

[0056] The inner tray 4 can be switched between a contracted state and a lifted state. When the packaging box 1 is in the open state, the inner tray 4 is in the lifted 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 contracted state, and the packaged item cannot be exposed / cannot be displayed; at least a part of the inner tray 4 in the lifted state is farther from the base plate of the packaging box 1 than this part of the inner tray 4 in the contracted 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 carrier 42. One end of the first reinforcing plate 436 away from the carrier 42 and one end of the second reinforcing plate 480 away from the carrier 42 are both movably arranged relative to the carrier 42; specifically: one end of the first reinforcing plate 436 is connected to the first connecting portion 431 / the first lifting portion 433, and other parts of the first reinforcing plate 436 are not connected to the first connecting portion 431 / the first lifting portion 433. The second reinforcing plate 480 is connected to the second connecting portion 432 / the second lifting portion 437, and other parts of the second reinforcing plate 480 are not connected to the second connecting portion 432 / the second lifting portion 437.

[0058] When the inner tray 4 is in the lifted state, the first reinforcing plate 436 is disengaged from the right pull box 3, and the second reinforcing plate 480 is disengaged from 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 portion 433 is located, and the plane where the second reinforcing plate 480 is located is not perpendicular to the plane where the second lifting portion 437 is located. When the inner tray 4 is in the contracted state, the first reinforcing plate 436 abuts against the right pull box 3 / the sixth side plate 35, and the second reinforcing plate 480 abuts against the left pull box 2 / the 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 carrier 42 can be prevented, the stability of the inner tray 4 is increased, the shaking of the inner tray 4 is avoided, and further the stability of the packaged item is affected, and the damage of the packaged item is further ensured.

[0059] When the packaging box 1 is in the closed state, at least one of the spaces is formed between the first lifting portion 433 and the sixth side plate 35 and between the second lifting portion 437 and the third side plate 25, and the smaller the space is, 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 is, and / or the smaller the distance between the second reinforcing plate 480 and the third side plate 235 is, the more stable the inner tray 4 is in the packaging box 1, and the packaged item is less likely to be damaged.

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

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

[0062] In some preferred embodiments, the extending direction of one end of the first reinforcing plate 436 for abutting against the sixth side plate 35 of the right pull box 3 is parallel to the sixth side plate 35, and / or the extending direction of one end of the second reinforcing plate 480 for abutting 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, in the up-down direction, at least one of the first reinforcing plate 436 and the second reinforcing plate 480 is flush with the connecting member 43.

[0064] According to the above description, during the movement of the inner tray 4 from the contracted state towards the lifted state, force can be stably transmitted between at least one of the left pull box 2 and the right pull box 3 and the inner tray 4, thereby further preventing the carrier 42 from deforming or moving and preventing the packaged item from being damaged.

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

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

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

[0068] When the left pull box 2 is pulled in a direction away from the right pull box 3, as the left pull box 2 moves, the second fixing portion 439 moves in a direction away from the right pull box 3 together with the left pull box 2, and the second lifting portion 437 is driven by the second fixing portion 439 to move in a direction away from the right pull box 3. After that, the second connecting portion 432 drives the first connecting portion 431 to move upward, the inner tray 4 moves from the contracted state to the lifted state, the packaging box 1 changes from the closed state to the opened state, and the packaged item is exposed / displayed through the exposure opening.

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

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

[0071] When the right pull box 3 is pushed towards the direction close to the left pull box 2, and / or when the left pull box 2 is pushed towards the direction close to the right pull box 3, with the movement of the right pull box 3 and / or the left pull box 2, the inner tray 4 / carrying member 42 moves downward under its own gravity, and both the first fixing portion 435 and the second fixing portion 439 are driven by the carrying member 42 to move downward together. The inner tray 4 moves from the lifted state to the contracted state, and the packaging box 1 changes from the opened state to the closed state.

[0072] During the process of the packaging box 1 changing from the opened 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 the present invention has the following beneficial effects:

[0075] In the first aspect, during the process of the packaging box 1 changing from the closed state to the opened 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 portion 435 can drive the first lifting portion 433 to move upward together. Then, the first lifting portion 433 drives the carrying member 42 to move upward, and then the carrying member 42 drives the second lifting portion 437 to move. Or, the second fixing portion 437 can drive the second lifting portion 437 to move upward together. Then, the second lifting portion 437 drives the carrying member 42 to move upward, and then the carrying member 42 drives the first lifting portion 433 to move. Or, while the first fixing portion 435 drives the first lifting portion 433 to move upward, the second fixing portion 437 drives the second lifting portion 437 to move upward. The first lifting portion 433 and the second lifting portion 437 drive the carrying member 42 to move upward at the same time. The inner tray 4 moves from the contracted state to the lifted state, and the packaged article is lifted together with the inner tray 4. This is convenient for people to take out the packaged article and has a good display effect.

[0076] In the second aspect, the inner tray 4 of the packaging box 1 includes a third bottom plate 41 and a carrying member 42 that are connected to each other. After the inner tray 4 is formed, a second accommodation cavity 44 can be formed between the carrying member 42 and the third bottom plate 41, and at least a part of the packaged article can be accommodated in the second accommodation cavity 44.

[0077] The carrying member 42 further has a squeezed portion 421 that can move relative to the main body 422. When the packaged article is placed on the inner tray 4, the squeezed portion 421 can squeeze the packaged article so that the packaged article is fixed more stably.

[0078] In a third aspect, according to the description of the second aspect, the arrangement of the squeezed portion 421 can also enable the second accommodating cavity 44 to accommodate and fix packaged articles of different sizes and different shapes, and the application range of the packaging box 1 is widened.

[0079] In a fourth aspect, according to the first aspect, the first fixing portion 435 can be fixed to the outer surface of the sixth side plate 35 of the right pull box 3, and the second fixing portion 439 can be fixed to the outer surface of the third side plate 25 of the left pull box 2. In this setting, during the process of the packaging box 1 changing from the closed state to the open state, the first fixing portion 435 will not be subjected to a force opposite to the moving direction of the right pull box 3. Therefore, the first fixing portion 435 will not have a tendency to move away from the right pull box 3; or, the second fixing portion 437 will not be subjected to a force opposite to the moving direction of the left pull box 2, and the second fixing portion 437 will not have a tendency to move away from the left pull box 2, strengthening the connection between the inner tray 4 and the left pull box 2 and the right pull box 3, improving the stability of the inner tray 4 in the packaging box 1, and further reducing the possibility of the packaged articles falling during the movement process.

[0080] In a fifth aspect, a first reinforcing plate 436 and a second reinforcing plate 480 are respectively arranged on the first connecting portion 431 and the second connecting portion 432 of the inner tray 4. When the packaging box 1 is in the closed state, the first reinforcing plate 436 can be in contact with the sixth side plate 35, and the second reinforcing plate 480 can be in contact with 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.
