Description

Technical Field

[0001] This invention relates to the field of packaging technology, and more specifically, to a cover assembly and a packaging box. Background Technology

[0002] Packaging boxes are very common in daily life, used to hold foods such as candy, making them convenient for users to carry. In related technologies, packaging boxes typically open or close the dispensing port directly through a sliding cover, which results in poor sealing of the dispensing port. Furthermore, the lid assembly of these packaging boxes has a complex structure, making them inconvenient to manufacture. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0004] To this end, the first aspect of the present invention provides a cover assembly.

[0005] A second aspect of the present invention provides a packaging box.

[0006] The first aspect of the present invention provides a cover assembly, comprising: a cover having an opening; a sliding cover slidably disposed on the cover; and a flip cover located between the cover and the sliding cover and rotatably connected to the cover, thereby opening or closing the opening when driven by the sliding cover.

[0007] This invention proposes a cover assembly, including a cover body, a sliding cover, and a flip cover. The cover body has an opening that can be used as a discharge port when the cover assembly is installed onto the body of a packaging box. The flip cover is positioned at the opening. The sliding cover is slidably mounted on the cover body and can drive the flip cover to open or close the opening during sliding.

[0008] Specifically, when the sliding cover slides in one direction, it drives the flip cover to open the opening on the casing, allowing food items such as candy or medicine to be removed from the box. When the sliding cover slides in the other direction, it drives the flip cover to close the opening on the casing, preventing food from leaking out of the box.

[0009] Furthermore, this invention utilizes a sliding cover to drive the flip-top movement during the sliding process, thereby opening or closing the opening. On one hand, the flip-top effectively seals the opening, preventing the storage of materials inside the packaging box. On the other hand, the sliding cover directly drives the flip-top, simplifying the overall structure and reducing the number of parts in the lid assembly. This results in a compact packaging box structure using this lid assembly, while also reducing the cost of the lid assembly. Moreover, opening or closing the opening on the cover via sliding conforms to user habits, facilitating daily operation and making it extremely compact and convenient. Compared to existing structures that typically require two hands, the lid assembly of this application only requires one hand to open or close the opening, providing users with a fun and dynamic way to open and close.

[0010] The lid assembly proposed in this invention can directly drive the flip-top movement through the sliding cover during the sliding process, so that the flip-top can open or close the opening. The whole structure is small and exquisite, easy for users to operate, and can reduce the cost of the lid assembly while ensuring the food storage inside the packaging box.

[0011] The cover assembly according to the above-described technical solution of the present invention may further have the following additional technical features:

[0012] In the above technical solution, the flip cover includes: a flip cover body; a first rotating shaft disposed on the flip cover body and rotatably connected to the cover body; a protrusion disposed on a wall of the flip cover body facing the sliding cover; wherein, when the sliding cover slides in one direction, it can push the protrusion to drive the flip cover body to open the opening, and when the sliding cover moves in the opposite direction, it can push the flip cover body to drive the flip cover body to close the opening.

[0013] In this technical solution, the flip cover includes a flip cover body, a first rotating shaft, and a protrusion. The first rotating shaft is disposed on the flip cover body and rotatably connected to the cover, allowing the flip cover body to rotatably cover the opening. The protrusion is disposed on the wall of the flip cover body facing the sliding cover and protrudes beyond the flip cover body, ensuring that the sliding cover can push the protrusion during sliding in one direction, thereby driving the protrusion to rotate the flip cover body and open the opening on the cover. When the opening is open, the flip cover body is in an upright state; as the sliding cover slides in the other direction, it pushes the flip cover body, thereby causing the flip cover body to close the opening.

[0014] In any of the above technical solutions, the flip cover also includes a second pivot, which protrudes from the protrusion; the cover body is provided with a guide groove, and the second pivot is located in the guide groove when the flip cover body is opened.

[0015] In this technical solution, the flip cover also includes a second pivot, and the cover body is provided with a guide groove that cooperates with the second pivot. The second pivot protrudes from the side wall of the protrusion, and when the flip cover body is opened, the second pivot is in the guide groove and abuts against the inner wall of the guide groove to support the flip cover body and ensure that the flip cover body is stably in an upright state.

[0016] In any of the above technical solutions, when the flip cover body closes the opening, the included angle formed between the flip cover body and the plane where the opening is located is less than or equal to 90°; wherein, the opening and the included angle are located on the same side of the flip cover body.

[0017] In this technical solution, when the flip cover is at its maximum opening angle, it is in an upright position and forms an angle with the plane containing the opening, which is less than or equal to 90°. This ensures that the tilt angle of the flip cover relative to the plane containing the opening is less than or equal to 90° when it is in the open state, guaranteeing that the flip cover can smoothly return to its original position when the sliding cover moves in the opposite direction of the cover. Specifically, the opening and the angle are located on the same side of the flip cover; that is, the aforementioned angle can be understood as the maximum rotation angle of the flip cover.

[0018] In any of the above technical solutions, when the flip cover body closes the opening, the included angle formed between the flip cover body and the plane where the opening is located is greater than 90°; wherein the opening and the included angle are located on the same side of the flip cover body.

[0019] In this technical solution, when the flip cover is at its maximum opening angle, it is in an upright position, forming an angle greater than 90° with the plane containing the opening. This ensures sufficient space between the upright flip cover and the plane containing the opening, facilitating the removal of candies, medicines, and other food items from the box and making it easier to operate. Specifically, the opening and the angle are located on the same side of the flip cover, which can be understood as the maximum rotation angle of the flip cover. In any of the above technical solutions, the cover has a receiving groove, with the opening located on the bottom wall of the receiving groove; the flip cover can be accommodated within the receiving groove, and the protrusion is located outside the receiving groove.

[0020] In this technical solution, the cover body is provided with a receiving groove. The opening is located on the bottom wall of the receiving groove. When the flip cover body closes the opening on the cover body, both the flip cover body and the first rotating shaft are inside the receiving groove. This ensures the miniaturization and thinness of the cover body assembly, and also prevents the flip cover body and the first rotating shaft from affecting the sliding of the cover.

[0021] Furthermore, when the flip cover closes the opening on the cover, the protrusion is located outside the receiving groove to ensure that the sliding cover can be pushed to the protrusion, so that the sliding cover can drive the flip cover to rotate through the protrusion to open the opening on the cover.

[0022] In any of the above technical solutions, the cover includes: a cover body with an opening disposed on the cover body; a movable block disposed on the side of the cover body facing the sliding cover, the sliding cover covering the movable block and slidably connected to the movable block.

[0023] In this technical solution, the cover includes a cover body and a movable block. The cover body has the aforementioned opening, and the movable block is mounted on the cover body, located on the side of the cover body facing the sliding cover. The sliding cover is mounted on the movable block and can be directly slidably connected to it, ensuring that the user can push the sliding cover. Furthermore, the movable block, located below the sliding cover, also serves to support the sliding cover, preventing dents and deformations caused by external impacts and ensuring the service life of the cover assembly.

[0024] In any of the above technical solutions, the side wall of the movable block is provided with a guide protrusion or a guide groove, which extends along the sliding direction of the sliding cover; the sliding cover has a surrounding edge, which is slidably connected to the guide protrusion or guide groove.

[0025] In this technical solution, the sidewall of the movable block is provided with a guide protrusion or a guide groove, and the sliding cover has a surrounding edge. The guide protrusion or guide groove extends along the sliding direction of the sliding cover, and the surrounding edge of the sliding cover is slidably connected to the guide protrusion or guide groove. This ensures that the sliding cover can slide along the extension direction of the guide protrusion or guide groove, and also ensures that the sliding cover and the movable block are limited in the thickness direction of the cover assembly, preventing the sliding cover from falling off the movable block during use.

[0026] In any of the above technical solutions, the movable block is located to the side of the opening; the movable block has an abutting surface on the side facing the opening, and the sliding cover can abut against the abutting surface.

[0027] In this technical solution, the movable block is located to the side of the opening, and an abutment surface is provided on the movable block. The abutment surface is located on the side of the movable block facing the opening and can be used for abutment and limiting of the sliding cover.

[0028] Specifically, the sliding cover slides in one direction toward the cover and drives the flip cover to open the opening on the cover. Then the sliding cover slides to its farthest distance and comes into contact with the contact surface, ensuring that the contact surface limits the sliding travel of the sliding cover and preventing the sliding cover from sliding excessively and damaging the flip cover.

[0029] In any of the above technical solutions, the cover further includes: a snap-fit ​​portion, which protrudes from the side of the cover body facing the sliding cover, and the snap-fit ​​portion is disposed away from the moving block, and the sliding cover can be snapped into the snap-fit ​​portion.

[0030] In this technical solution, the cover also includes a snap-fit ​​part. The snap-fit ​​part is located on the side of the cover body facing the sliding cover and protrudes from the cover body. The snap-fit ​​part and the moving block are located on opposite sides of the flip cover, and the sliding cover can be snapped into the snap-fit ​​part.

[0031] Specifically, when the flip cover closes the opening, the sliding cover engages with the locking part, thereby ensuring the positioning of the sliding cover, preventing the sliding cover from sliding accidentally, and preventing the sliding cover from detaching from the moving block due to excessive sliding.

[0032] In any of the above technical solutions, the cover body, the moving block, and the snap-fit ​​part are an integrated structure.

[0033] In this technical solution, the cover body, the moving block, and the snap-fit ​​part are integrated into a single structure and can be integrally machined. This reduces the number of manufacturing steps required for the cover while ensuring its own strength, thus guaranteeing the service life of the cover assembly.

[0034] In any of the above technical solutions, the flip cover body, the first pivot, the protrusion, and the second pivot are an integral structure.

[0035] In this technical solution, the flip cover body, the first pivot, the protrusion, and the second pivot are an integral structure that can be integrally machined and assembled onto the cover. This reduces the manufacturing process of the flip cover while ensuring its own strength, thus guaranteeing the service life of the cover assembly.

[0036] In any of the above technical solutions, the cover assembly further includes: a decorative part disposed on a wall of the sliding cover away from the cover body.

[0037] In this technical solution, the cover assembly also includes a decorative section. This decorative section is located on a side of the sliding cover that faces away from the main body, enhancing the aesthetic appearance of the cover assembly and serving as a distinguishing feature.

[0038] Specifically, the decorative section may use a decorative layer and cover the wall of the sliding cover away from the cover body. Product information and patterns may be set on the decorative layer.

[0039] In any of the above technical solutions, the cover is made of plastic.

[0040] In this technical solution, the plastic parts can be made of plastic. Plastic parts have good plasticity and can provide good insulation between the sliding cover and the box body, especially when both the box body and the sliding cover are made of metal, thus avoiding rigid contact and eliminating noise during the sliding process.

[0041] In any of the above technical solutions, the sliding cover is a metal component.

[0042] In this technical solution, the sliding cover is made of metal. Metal parts have good rigidity and hardness, can withstand greater external forces, and prevent the sliding cover from deforming or denting due to external impacts, thus ensuring the service life of the cover assembly.

[0043] In any of the above technical solutions, the flip cover is made of plastic.

[0044] In this technical solution, the flip cover is made of plastic. Plastic parts have good shaping and sealing properties. This ensures that the flip cover will not make noise when it is opened and closed due to impact, and also ensures the sealing of the opening, thereby ensuring the preservation of the food inside the box.

[0045] A second aspect of the present invention provides a packaging box, comprising: a box body having a cavity; and a cover assembly as described in the first aspect of the present invention, wherein the cover is connected to the box body and the opening communicates with the cavity.

[0046] The packaging box proposed in this invention includes a box body and a lid assembly as described in any of the above technical solutions. Therefore, it possesses all the beneficial effects of the aforementioned lid assembly, which will not be elaborated upon here.

Detailed Implementation

[0067] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, features of the same embodiments and different embodiments of this application can be combined with each other.

[0068] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0069] The following reference Figures 1 to 14 This describes a cover assembly 100 and a packaging box provided according to some embodiments of the present invention. Figure 2 The solid arrow indicates the sliding direction of the cover 106 when the opening 104 is open, and the dashed arrow indicates the sliding direction of the cover 106 when the opening 104 is closed.

[0070] like Figure 1 and Figure 2 As shown, the first embodiment of the present invention proposes a cover assembly 100, including a cover 102, a sliding cover 106 and a flip cover 108.

[0071] The cover 102 is provided with an opening 104, which can be used as a discharge port when the cover assembly 100 is installed on the box body 200 of the packaging box; the flip cover 108 is located at the opening 104, and the sliding cover 106 is slidably installed on the cover 102, and can drive the flip cover 108 to move during the sliding process, so that the flip cover 108 opens or closes the opening 104.

[0072] Specifically, such as Figure 2 As shown, when the sliding cover 106 slides in the direction indicated by the solid arrow, the sliding cover 106 can drive the flip cover 108 to move during the sliding process, so that the flip cover 108 opens the opening 104 on the cover 102, and the material can be taken out from the opening 104. When the sliding cover 106 slides in the direction indicated by the dashed arrow, the sliding cover 106 can drive the flip cover 108 to move during the sliding process, so that the flip cover 108 closes the opening 104 on the cover 102, thus preventing the material from being exposed from the box body 200 of the packaging box.

[0073] Furthermore, in this embodiment, the sliding cover 106 drives the flip cover 108 to move during the sliding process, thereby opening or closing the opening 104. On the one hand, the flip cover 108 can effectively seal the opening 104, which is beneficial for storing materials inside the box body 200 of the packaging box. On the other hand, the sliding cover 106 can directly drive the flip cover 108, simplifying the overall structure, reducing the number of parts in the cover assembly 100, making the packaging box structure using this cover assembly 100 compact, and reducing the cost of the cover assembly 100.

[0074] Furthermore, the opening 104 on the cover 102 can be opened or closed by sliding, which conforms to the user's usage habits, facilitates daily operation, and is very compact and convenient. Moreover, compared to existing structures that usually require the user to operate with both hands, the cover component 100 of this application can open or close the opening 104 with only one hand, providing the user with a fun and dynamic way to open and close.

[0075] Therefore, the cover assembly 100 proposed in this embodiment can directly drive the flip cover 108 to move through the sliding cover 106 during the sliding process, so that the flip cover 108 can open or close the opening 104. The whole structure is small and exquisite, easy for users to operate, and can reduce the cost of the cover assembly 100 while ensuring the storage of food in the box body 200 of the packaging box.

[0076] The second embodiment of the present invention provides a cover assembly 100, which, based on the first embodiment, further includes:

[0077] like Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the flip cover 108 includes a flip cover body 110, a first rotating shaft 112, and a protrusion 114. The first rotating shaft 112 is disposed on the flip cover body 110 and rotatably connected to the cover 102, so that the flip cover body 110 can rotatably cover the opening 104. The protrusion 114 is disposed on the side of the flip cover body 110 facing the sliding cover 106 and protrudes from the flip cover body 110, ensuring that the sliding cover 106 can push the protrusion 114 during the sliding process in the direction indicated by the solid arrow, thereby driving the protrusion 114 to drive the flip cover body 110 to rotate, so that the flip cover body 110 opens the opening 104 on the cover 102. When the opening 104 is in the open state, the flip cover body 110 is in the upright state. During the sliding process of the sliding cover in the other direction, it can push the flip cover body 110, thereby driving the flip cover body 110 to close the opening 104.

[0078] Specifically, such as Figure 2As shown, when the sliding cover 106 slides in the direction indicated by the solid arrow, the sliding cover 106 can be pushed to one side of the protrusion 114 during the sliding process. At this time, the protrusion 114 drives the flip cover body 110 to rotate to one side, and the flip cover body 110 opens the opening 104 on the cover 102. When the opening 104 is in the open state, the flip cover body 110 is in the upright state, and the protrusion 114 is in the horizontally arranged state. When the sliding cover 106 slides in the direction indicated by the dashed arrow, the sliding cover 106 can be pushed to the flip cover body 110 during the sliding process. At this time, the flip cover body 110 rotates to the other side, and the flip cover body 110 closes the opening 104 on the cover 102.

[0079] In this embodiment, further, as Figure 3 As shown, the flip cover 108 also includes a second pivot 116, and the cover body 102 is provided with a guide groove 118 that cooperates with the second pivot 116. The second pivot 116 protrudes from the side wall of the protrusion 114, and when the flip cover body 110 opens the opening 104, the second pivot 116 is located in the guide groove 118 and abuts against the inner wall of the guide groove 118, so as to support the flip cover body 110 and ensure that the flip cover body 110 is stably in an upright state.

[0080] In specific embodiments, such as Figure 1 As shown, when the flip cover body 110 is at its maximum opening angle with the opening 104 open, the flip cover body 110 is in an upright state, and an angle α is formed between the flip cover body 110 and the plane containing the opening 104, which is less than or equal to 90°. This ensures that the tilt angle of the flip cover body 110 in the open state relative to the plane containing the opening 104 is less than or equal to 90°, guaranteeing that the flip cover body 110 can smoothly return to its original position when the sliding cover 106 slides in the other direction of the cover 102.

[0081] In a specific embodiment, when the flip cover body 110 is at its maximum opening angle and the opening 104 is open, the flip cover body 110 is in an upright state, forming an angle α with the plane containing the opening 104, which is greater than 90°. This ensures sufficient space between the flip cover body 110 in its upright state and the plane containing the opening 104, thus facilitating the removal of candies, medicines, and other food items from the box body 200 and making it easier to operate.

[0082] Specifically, the opening 104 and the included angle α are located on the same side of the flip cover body 110, that is, the included angle α can be understood as the maximum rotation angle of the flip cover body 110. Specifically, the plane where the opening 104 is located is the end face of the cover body 122.

[0083] In this embodiment, further, as Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the flip cover body 110, the first pivot 112, the protrusion 114, and the second pivot 116 are an integral structure and can be integrally processed and assembled onto the cover 102. In this way, on the one hand, the processing and manufacturing steps of the flip cover 108 can be reduced, and on the other hand, the strength of the flip cover 108 itself can be guaranteed to ensure the service life of the cover assembly 100.

[0084] The third embodiment of the present invention proposes a cover assembly 100, which, based on the first embodiment, further includes:

[0085] like Figure 1 As shown, the cover 102 is provided with a receiving groove 120. The opening 104 is located on the bottom wall of the receiving groove 120. When the flip cover body 110 closes the opening 104 on the cover 102, both the flip cover body 110 and the first rotating shaft 112 are inside the receiving groove 120. This ensures the miniaturization and thinness of the cover assembly 100 and prevents the flip cover body 110 and the first rotating shaft 112 from affecting the sliding of the sliding cover 106.

[0086] Furthermore, when the flip cover body 110 closes the opening 104 on the cover 102, the protrusion 114 is located outside the receiving groove 120 to ensure that the sliding cover 106 can be pushed to the protrusion 114, so that the sliding cover 106 can drive the flip cover body 110 to rotate through the protrusion 114 to open the opening 104 on the cover 102.

[0087] The fourth embodiment of the present invention provides a cover assembly 100, which, based on the first embodiment, further includes:

[0088] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the cover 102 includes a cover body 122 and a movable block 124. The cover body 122 has the aforementioned opening 104. The movable block 124 is disposed on the cover body 122 and is located on the side of the cover body 122 facing the sliding cover 106. The sliding cover 106 covers the movable block 124 and can be directly slidably connected to the movable block 124, ensuring that the user can push the sliding cover 106. In addition, the movable block 124, located below the sliding cover 106, also serves to support the sliding cover 106, preventing the sliding cover 106 from being dented or deformed due to external impact, thus ensuring the service life of the cover assembly 100.

[0089] In this embodiment, further, as Figure 2 , Figure 6 and Figure 12As shown, the side wall of the movable block 124 is provided with a guide protrusion 126, and the sliding cover 106 has a surrounding edge 128. The guide protrusion 126 extends along the sliding direction of the sliding cover 106, and the surrounding edge 128 of the sliding cover 106 is slidably connected to the guide protrusion 126, ensuring that the sliding cover 106 can slide along the extending direction of the guide protrusion 126, and also ensuring the limiting between the sliding cover 106 and the movable block 124 in the thickness direction of the cover assembly 100, so as to prevent the sliding cover 106 from falling off the movable block 124 during use.

[0090] In another embodiment, a guide groove (not shown in the figure) can be used instead of a guide protrusion 126, and the edge of the slide cover 106 adopts a structure that matches the guide groove. This also enables the slide cover 106 to slide along the extension direction of the guide groove, and ensures the limiting between the slide cover 106 and the moving block 124, preventing the slide cover 106 from falling off the moving block 124 during use.

[0091] In this embodiment, further, as Figure 1 As shown, the movable block 124 is located to the side of the opening 104, and the movable block 124 is provided with an abutment surface 132. The abutment surface 132 is located on the side of the movable block 124 facing the opening 104, and can be used for the abutment and limiting of the sliding cover 106.

[0092] Specifically, such as Figure 2 As shown, when it is necessary to open the opening 104, the sliding cover 106 slides in one direction toward the cover 102, and drives the flip cover 108 to move during the sliding process, so that the flip cover 108 opens the opening 104 on the cover 102. Then the sliding cover 106 slides to the farthest distance and abuts against the contact surface 132, ensuring that the contact surface 132 limits the sliding stroke of the sliding cover 106, and preventing the sliding cover 106 from sliding excessively and damaging the flip cover 108.

[0093] In this embodiment, further, as Figure 1 , Figure 3 , Figure 5 and Figure 13 As shown, the cover 102 also includes a snap-fit ​​portion 130. The snap-fit ​​portion 130 is disposed on a wall of the cover body 122 facing the sliding cover 106 and protrudes from the cover body 122. The snap-fit ​​portion 130 and the movable block 124 are located on opposite sides of the flip cover 108, and the sliding cover 106 can be snapped into the snap-fit ​​portion 130.

[0094] Specifically, when the flip cover 108 closes the opening 104, the sliding cover 106 engages with the locking part 130, thereby ensuring the positioning of the sliding cover 106 and preventing the sliding cover 106 from sliding accidentally.

[0095] In this embodiment, further, as Figure 5 and Figure 6As shown, the cover body 122, the movable block 124, and the snap-fit ​​part 130 are an integral structure and can be integrally processed and formed. In this way, on the one hand, the processing and manufacturing steps of the cover body 102 can be reduced, and on the other hand, the strength of the cover body 102 itself can be guaranteed to ensure the service life of the cover assembly 100.

[0096] The fifth embodiment of the present invention provides a cover assembly 100, which, based on the first embodiment, further includes:

[0097] The cover assembly 100 also includes a decorative portion (not shown in the figure). The decorative portion is located on the side of the sliding cover 106 opposite to the cover body 102 to enhance the aesthetic appearance of the cover assembly 100 and to serve as a marker for differentiation.

[0098] Specifically, the decorative part may be a decorative layer, which covers the side of the sliding cover 106 away from the cover body 102. The decorative layer may be provided with product information and patterns.

[0099] Based on Embodiments 1 to 5, the cover 102 can be made of plastic. Plastic has good plasticity and can provide good insulation between the sliding cover 106 and the box body 200 of the packaging box, especially when both the box body 200 and the sliding cover 106 are made of metal, thus avoiding rigid contact and eliminating noise during the sliding process of the sliding cover 106.

[0100] Based on Embodiments 1 to 5, the sliding cover 106 is further made of metal. Metal parts have good rigidity and hardness, can withstand greater external forces, and prevent the sliding cover 106 from deforming or denting due to external impact, thus ensuring the service life of the cover assembly 100.

[0101] Based on Embodiments 1 to 5, the flip cover 108 is further made of plastic. Plastic parts have good shaping and sealing properties. In this way, on the one hand, it can be ensured that no noise is generated due to collision when the flip cover 108 opens and closes the opening 104, and on the other hand, the sealing of the opening 104 is guaranteed, thereby ensuring the preservation effect of the food inside the box body 200.

[0102] like Figure 14 As shown, the sixth embodiment of the present invention proposes a packaging box, including a box body 200 and a cover assembly 100 as described in any of the above embodiments.

[0103] The packaging box proposed in this embodiment of the invention includes any of the cover components 100 described above. Therefore, it possesses all the beneficial effects of the cover components 100 described above, which will not be discussed in detail here.

[0104] Specifically, such as Figure 14As shown, the box body 200 has a cavity that can be used to store food such as candy and medicine. A cover 102 is connected to the box body 200, and an opening 104 on the cover 102 communicates with the cavity of the box body 200. By driving the sliding cover 106 to slide, the flip cover 108 can open or close the opening 104 on the cover 102, allowing the user to retrieve food from the cavity.

[0105] In this specific embodiment, the box body 200 is made of metal. Thus, both the sliding cover 106 and the box body 200 are made of metal, ensuring the strength and lifespan of the packaging box. The cover 102 is made of plastic and is located between the box body 200 and the sliding cover 106, providing a good buffer transition.

[0106] like Figure 14 As shown, the first specific embodiment of the present invention proposes a packaging box that can be used to hold foods such as candy. The packaging box includes a lid assembly 100 and a box body 200.

[0107] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cover assembly 100 includes a cover 102, a sliding cover 106, and a flip cover 108. The cover 102 has an opening 104, the flip cover 108 is located at the opening 104, the sliding cover 106 is slidably mounted on the cover 102, and can drive the flip cover 108 to move during sliding, so that the flip cover 108 opens or closes the opening 104.

[0108] Specifically, such as Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the flip cover 108 includes a flip cover body 110, a first pivot 112, a protrusion 114, and a second pivot 116. The flip cover body 110 is rotatably connected to the cover 102 via the first pivot 112 and is rotatably positioned over the opening 104. The protrusion 114 protrudes from the side of the flip cover body 110 facing the sliding cover 106, ensuring that the sliding cover 106 can push the protrusion 114 during its sliding motion in the direction indicated by the solid arrow, thereby driving the protrusion 114 to rotate the flip cover body 110, so that the flip cover body 110 opens the opening 104 on the cover 102. When the opening 104 is open, the flip cover body 110 is in an upright state. During the sliding motion of the sliding cover 106 in the other direction, the flip cover body 110 can be pushed, thereby causing the flip cover body 110 to close the opening 104.

[0109] Furthermore, the second rotating shaft 116 engages with the guide groove 118 on the cover 102 to ensure the rotation angle of the flip cover body 110. Specifically, when the flip cover body 110 closes the opening 104, the second rotating shaft 116 is within the guide groove 118, and the flip cover body 110 is in an upright state. At this time, an angle α is formed between the flip cover body 110 and the plane containing the opening 104. This angle α can be less than or equal to 90° to ensure that the flip cover body 110 can be smoothly reset. In addition, this angle α can also be greater than 90°, which is more conducive to the removal of candies, medicines, and other food items from the box body 200, making it easier to operate.

[0110] Specifically, such as Figure 1 As shown, the cover 102 is provided with a receiving groove 120, and the opening 104 is provided on the bottom wall of the receiving groove 120. When the flip cover body 110 closes the opening 104 on the cover 102, the flip cover body 110 and the first rotating shaft 112 are both inside the receiving groove 120, and the protrusion 114 is located outside the receiving groove 120.

[0111] Specifically, such as Figure 5 and Figure 6 As shown, the cover 102 includes a cover body 122 and a movable block 124. The cover body 122 is provided with the aforementioned opening 104. The sliding cover 106 covers the movable block 124 and can be directly slidably connected to the movable block 124. The side wall of the movable block 124 is provided with a guide protrusion 126 or a guide groove. The sliding cover 106 has a surrounding edge 128. The surrounding edge 128 of the sliding cover 106 is slidably connected to the guide protrusion 126 or the guide groove, ensuring that the sliding cover 106 can slide along the extension direction of the guide protrusion 126. At the same time, it also ensures the limiting of the sliding cover 106 and the movable block 124 in the thickness direction of the cover assembly 100, preventing the sliding cover 106 from falling off the movable block 124 during use.

[0112] Specifically, such as Figure 1 As shown, the movable block 124 is located to the side of the opening 104, and an abutment surface 132 is provided on the movable block 124. The abutment surface 132 is located on the side of the movable block 124 facing the opening 104, and can realize the abutment and limiting of the sliding cover 106. Figure 13 As shown, a snap-fit ​​portion 130 is provided on one wall of the cover body 122 facing the sliding cover 106. The sliding cover 106 can be snapped into the snap-fit ​​portion 130, and the other side of the sliding cover 106 can be abutted and limited.

[0113] Specifically, the flip cover body 110, the first pivot 112, the protrusion 114, and the second pivot 116 are an integral structure.

[0114] Specifically, the cover body 122, the movable block 124, and the snap-fit ​​part 130 are an integral structure.

[0115] Specifically, the cover assembly 100 also includes a decorative section. The decorative section may be a decorative layer that covers the side of the sliding cover 106 opposite to the cover body 102, and the decorative layer may be provided with product information and patterns.

[0116] Specifically, the cover 102 is made of plastic, the sliding cover 106 is made of metal, the flip cover 108 is made of plastic, and the box body 200 is made of metal.

[0117] Figure 15 yes Figure 14 The schematic diagram of the embodiment with the sliding cover shown shows that after the sliding cover 106 is returned to its position, it completely covers the box body 200, so that the packaging box of the present invention can ensure that the food or medicine inside the box is completely sealed and kept clean when closed. The surface of the packaging box has no additional protruding structures, which makes it easy to grip, store and transport.
