[0045] like Figures 1 to 4 as well as Figure 11 As shown, this application provides a packaging box for packaging medical devices. An embodiment of the packaging box includes an outer box body 1 and a supporting inner liner 2. The outer box body 1 has a receiving space; the supporting inner liner 2 is disposed within the receiving space. The supporting inner liner 2 includes a main unit box body 10, an accessory box body 20, and a fixing part 30. The main unit box body 10 and the accessory box body 20 are arranged side-by-side. The fixing part 30 is located at the end of the main unit box body 10 and / or the end of the accessory box body 20 and fixes the main unit box body 10 and the accessory box body 20. The supporting inner liner 2 is formed by folding a single sheet of paper template 3.

[0046] The technical scheme is applied to the packaging box, which comprises an outer box body 1 and a supporting inner liner 2, the supporting inner liner 2 is used for placing a main machine and accessories of a medical device, and the outer box body 1 is used for placing the supporting inner liner 2. The above-mentioned arrangement facilitates a user to open the packaging box and take the main machine and the accessories of the medical device. The supporting inner liner 2 comprises a main machine box body part 10, an accessory box body part 20 and a fixing part 30. The main machine box body part 10 is used for separately placing the main machine, can effectively fix the main machine and prevent damage of the main machine caused by collision during transportation. The accessory box body part 20 is used for placing the accessories. The main machine and the accessories are placed in different box body parts, which can effectively improve the fixing effect of the main machine and the accessories and prevent the main machine and the accessories from colliding with each other in the same space. The fixing part 30 can fix the main machine box body part 10 and the accessory box body part 20, so that the supporting inner liner 2 forms an integral structure. When the user takes out the main machine, the supporting inner liner 2 is prevented from being taken out and then being scattered, which affects the user to put the supporting inner liner 2 and the main machine back into the packaging box. The supporting inner liner 2 is folded from a paper template 3, which has the characteristics of easy-to-obtain raw materials, low cost and environmental protection. Therefore, the technical scheme of the embodiment can effectively solve the problem that the supporting inner liner folded from a piece of paper is easily scattered and the user cannot fold it back to the original state.

[0047] Specifically, the outer box body 1 comprises an upper box body 101 and a lower box body 102. The upper box body 101 is a rectangular parallelepiped with an open lower side, and the lower box body 102 is a rectangular parallelepiped with an open upper side. The lower box body 102 is used for placing the supporting inner liner 2, and the upper box body 101 is arranged above and outside the lower box body 102. The size of the upper box body 101 is slightly larger than that of the lower box body 102, so as to facilitate the cooperation between the upper box body 101 and the lower box body 102. The above-mentioned arrangement can further increase the buffering and isolation of the main machine and the accessories, prevent the product from being damaged by external collision and extrusion during transportation, and prevent the medical device from being damaged.

[0048] As Figure 3 , Figure 4 , Figure 8 , Figure 10 and Figure 11As shown, the fixing part 30 includes a first fixing plate 31 arranged at the end of the main box body part 10, a first end of the first fixing plate 31 is connected to the side of the main box body part 10 away from the accessory box body part 20, and a second end of the first fixing plate 31 is inserted and matched with the accessory box body part 20. Due to the relatively large size and weight of the host, the first fixing plate 31 is arranged on the outside of the main box body part 10, which can further improve the structural strength of the main box body part 10, so that the main box body part 10 is not easy to deform or spread out. Through the insertion and matching of the first fixing plate 31 and the accessory box body part 20, the main box body part 10 and the accessory box body part 20 can be fixed, preventing the user from taking out the product and bringing out the supporting liner 2 to separate or spread out the main box body part 10 and the accessory box body part 20. At the same time, the insertion and matching method can avoid using adhesive glue, which can effectively simplify the process steps and processes of folding the supporting liner 2 from a piece of paper template 3, thereby reducing production costs.

[0049] As shown in Figure 8 , Figure 10 and Figure 11 , one of the first fixing plate 31 and the accessory box body part 20 is provided with a socket 32, and the other is provided with a plug 21 that can be inserted into the socket 32. In this embodiment, the first fixing plate 31 is provided with the socket 32, and the accessory box body part 20 is provided with the plug 21. Through the insertion and matching of the socket 32 and the plug 21, the main box body part 10 and the accessory box body part 20 can be fixed, which has the advantages of simple structure and convenient operation, and can avoid using adhesive glue, which can effectively simplify the process steps and processes of folding the supporting liner 2 from a piece of paper template 3, thereby reducing production costs. In the embodiment not shown in the figure, the plug can be arranged on the first fixing plate, and the socket can be arranged on the accessory box body part.

[0050] As shown in Figure 8 and Figure 9As shown, the main box body part 10 and the accessory box body part 20 have a slot 40 therebetween, the fixing part 30 further comprises a plug plate 33 connected to one end of the first fixing plate 31 close to the accessory box body part 20, the plug plate 33 is inserted into the slot 40, and the socket 32 or the plug tongue 21 is arranged at the joint position of the first fixing plate 31 and the plug plate 33. Through the plug-in cooperation of the plug plate 33 and the slot 40, the main box body part 10 can form an overall structure under the constraint of the first fixing plate 31 and the plug plate 33, so as to avoid the main box body part 10 from being scattered during transportation or when the user takes out the main machine. In the embodiment, the socket 32 is arranged at the joint position of the first fixing plate 31 and the plug plate 33, and the socket 32 is plug-in cooperated with the plug tongue 21 on the accessory box body part 20, so as to fix the main box body part 10 and the accessory box body part 20, which has the advantages of simple structure and convenient operation. During the folding forming of the support lining 2, the plug plate 33 can be inserted into the slot 40 first, so that the positions of the first fixing plate 31 and the plug plate 33 are fixed, and then the plug tongue 21 is inserted into the socket 32, so as to facilitate the connection between the first fixing plate 31 and the accessory box body part 20. In the embodiment not shown in the figure, the plug tongue can also be arranged at the joint position of the first fixing plate and the plug plate, and the socket is arranged on the accessory box body part correspondingly.

[0051] As shown in Figure 3 , Figure 4 , Figure 8 , Figure 10 and Figure 11 , the accessory box body part 20 has a first side close to the main box body part 10 and a second side away from the main box body part 10, the fixing part 30 comprises a second fixing plate 34 and a third fixing plate 35, the second fixing plate 34 is connected with the first side of the accessory box body part 20 and extends towards the second side of the accessory box body part 20, the third fixing plate 35 is connected with the second side of the accessory box body part 20 and extends towards the first side of the accessory box body part 20, and the second fixing plate 34 and the third fixing plate 35 are plug-in cooperated. Through the above arrangement, the accessory box body part 20 can form an overall structure by itself, so as to avoid the accessory box body part 20 from being scattered during transportation or when the user takes out the main machine and the accessory, and ensure the integrity of the support lining 2.

[0052] Specifically, one of the second fixing plate 34 and the third fixing plate 35 is provided with a socket 351, and the other of the second fixing plate 34 and the third fixing plate 35 is provided with a plug tongue 341 capable of being inserted into the socket 351.

[0053] As shown in Figure 8As shown, in the embodiment, the second fixing plate 34 is provided with a tongue 341, and the third fixing plate 35 is provided with a socket 351, and the socket 351 and the tongue 341 are matched to fix the accessory box body 20, which has the advantages of simple structure and convenient operation, avoids using adhesive, effectively simplifies the process steps and procedures of folding the support liner 2 from the paper template 3, and further reduces the production cost. In an embodiment not shown in the figure, a socket can be provided on the second fixing plate, and a tongue is correspondingly provided on the third fixing plate.

[0054] As shown in Figures 4 to 11 , the main machine box body 10 includes a first bottom plate 11 and a side wall plate 12 arranged on the outer periphery of the first bottom plate 11, and the side wall plate 12 is a multi-layer structure. By arranging the first bottom plate 11 and the side wall plate 12 arranged on the outer periphery of the first bottom plate 11, the main machine box body 10 forms an open-top box structure for placing and fixing the main machine, and the side wall plate 12 is a multi-layer structure, which can ensure the structural strength of the main machine box body 10, so that the main machine box body 10 is not easy to deform and spread, and at the same time can ensure that the main machine box body 10 has a certain buffering effect.

[0055] In the embodiment, the support liner 2 and the outer box body 1 are all made of paper, which is a completely degradable and environmentally friendly material that meets green environmental protection requirements. In addition, since the support liner 2 is folded from a paper template 3 and the positions of the support liner 2 that are more likely to be impacted are arranged as a multi-layer structure and provided with a fixing part 30, a thinner paper template 3 can be used to make the support liner 2, while the structural strength of the support liner 2 can be ensured, which is lower in cost, smaller in size, and has the advantage of simple processing technology (specifically, a knife die stamping process can be used to form the paper template 3) compared to a paper pulp molding scheme (due to process precision limitations, the minimum thickness of the support liner formed by the paper pulp molding method is much larger than the required thickness, which consumes a large amount of paper pulp, making the cost higher).

[0056] As shown in Figure 6 and Figure 7 , the side wall plate 12 has a buffer space 120. By arranging the buffer space 120 in the side wall plate 12, the buffering capacity of the main machine box body 10 can be further improved to avoid damage to the main machine caused by external impact during transportation.

[0057] As shown in Figures 4 to 6 and Figure 11As shown, the side wall plate 12 includes a first end plate 121 corresponding to the planar end of the medical device and a second end plate 122 corresponding to the curved end of the medical device, and the number of paper layers of the second end plate 122 is greater than that of the first end plate 121. The first end plate 121 corresponds to the planar end of the medical device and has a relatively small number of paper layers, which can reduce the amount of paper while ensuring support and buffering capacity; since the contact area between the curved end of the medical device and the second end plate 122 is relatively small, the impact force of the curved end of the medical device acting on the second end plate 122 is greater, and the number of paper layers of the second end plate 122 is set to be relatively large, which can ensure the support and buffering capacity of the second end plate 122 and avoid damage to the second end plate 122 due to the impact of the curved end.

[0058] Specifically, as shown in Figure 8 、 Figure 9 and Figure 11 , the first end plate 121 includes a sixth vertical plate 1211, a third connecting top plate 1212 and a seventh vertical plate 1213 connected in sequence, wherein the sixth vertical plate 1211 is connected with the first bottom plate 11 and extends away from the first bottom plate 11, the third connecting top plate 1212 is connected with one end of the sixth vertical plate 1211 away from the first bottom plate 11 and extends away from the accommodating cavity of the main machine box body 10, and the seventh vertical plate 1213 is connected with the third connecting top plate 1212 and extends towards the first bottom plate 11.

[0059] As shown in Figure 4 and Figures 4 to 11 , the second end plate 122 includes an eighth vertical plate 1221, a ninth vertical plate 1222, a connecting bottom plate 1223, a tenth vertical plate 1224, a fourth connecting top plate 1225 and an eleventh vertical plate 1226 connected in sequence, wherein the eighth vertical plate 1221 is connected with the first bottom plate 11 and extends away from the first bottom plate 11, the ninth vertical plate 1222 is connected with one end of the eighth vertical plate 1221 away from the first bottom plate 11 and extends towards the first bottom plate 11, the connecting bottom plate 1223 is connected with one end of the ninth vertical plate 1222 close to the first bottom plate 11 and extends away from the accommodating cavity of the main machine box body 10, the tenth vertical plate 1224 is connected with one end of the connecting bottom plate 1223 away from the first bottom plate 11 and extends away from the first bottom plate 11, the fourth connecting top plate 1225 is connected with one end of the tenth vertical plate 1224 away from the first bottom plate 11 and extends towards the accommodating cavity of the main machine box body 10, and the eleventh vertical plate 1226 is connected with one end of the fourth connecting top plate 1225 close to the first bottom plate 11 and extends towards the first bottom plate 11, wherein the eleventh vertical plate 1226 is located on the side of the ninth vertical plate 1222 away from the first bottom plate 11 and is arranged in a stacked manner with the ninth vertical plate 1222.

[0060] AsFigure 5 As shown, the first bottom plate 11 is in a quadrilateral structure, the first bottom plate 11 has a first side edge 111 close to the accessory box body part 20, a second side edge 112 away from the accessory box body part 20, and a third side edge 113 and a fourth side edge 114 between the first side edge 111 and the second side edge 112, the side wall plate 12 includes a first side plate 123 connected with the first side edge 111 and a second side plate 124 connected with the second side edge 112.

[0061] As shown in the drawings, Figure 6 In the direction from the third side edge 113 to the fourth side edge 114, the width of the first bottom plate 11 gradually increases, and the width of the first side plate 123 and / or the width of the second side plate 124 gradually decreases, so that the sum of the widths of the first bottom plate 11, the first side plate 123 and the second side plate 124 remains consistent in the direction from the third side edge 113 to the fourth side edge 114. The width of the first bottom plate 11 gradually increases in the direction from the third side edge 113 to the fourth side edge 114, which can be adapted to the width change of the host, so that the side wall plate 12 surrounding the outer periphery of the first bottom plate 11 can be adapted to the side surface and the end surface of the host, and the host can be stably fixed in the host box body part 10. The width of the first side plate 123 and / or the width of the second side plate 124 gradually decreases, which can keep the width of the host box body part 10 consistent to form a regular shape, and facilitate the storage of the support lining 2 in the outer box body 1.

[0062] Specifically, in the embodiment, in the direction from the third side edge 113 to the fourth side edge 114, the width of the first side plate 123 and the width of the second side plate 124 gradually decrease. Of course, in the embodiment not shown in the drawings, only the width of the first side plate can gradually decrease in the direction from the third side edge to the fourth side edge, or only the width of the second side plate can gradually decrease in the direction from the third side edge to the fourth side edge, which mainly depends on the shape of the medical equipment, as long as the host of the medical equipment can be placed in the host box body part and the width of the host box body part is consistent.

[0063] As shown in the drawings, Figure 7 and Figure 4As shown, the first bottom plate 11 is obliquely arranged in the direction from the third side edge 113 to the fourth side edge 114, and the bottom surface of the first side plate 123 and the bottom surface of the second side plate 124 are arranged in a flush manner and are lower than the lowermost end of the first bottom plate 11. The oblique arrangement of the first bottom plate 11 can be adapted to the shape of the product, so that when the host computer is placed in the host box body 10, the top surface of the host computer is flush with or slightly lower than the top surface of the host box body 10, which is more beautiful and convenient for the user to take out the host computer. The bottom surface of the first side plate 123 and the bottom surface of the second side plate 124 are arranged in a flush manner and are lower than the lowermost end of the first bottom plate 11, which can lift the obliquely arranged first bottom plate 11, so that the height of the host box body 10 remains consistent to form a regular shape, which facilitates the storage of the supporting lining 2 in the outer box body 1.

[0064] As shown in Figure 5 , Figures 7 to 9 , Figure 11 and Figure 4 , the side wall plate 12 includes a first side plate 123 arranged close to the accessory box body 20, and the first side plate 123 includes a first vertical plate 1231, a first connecting top plate 1232 and a second vertical plate 1233 connected in sequence, wherein the first vertical plate 1231 is connected with the first bottom plate 11 and extends away from the first bottom plate 11, the first connecting top plate 1232 is connected with one end of the first vertical plate 1231 away from the first bottom plate 11 and extends towards the accessory box body 20, and the second vertical plate 1233 is connected with the first connecting top plate 1232 and extends towards the first bottom plate 11. The accessory box body 20 includes a third side plate 22 arranged close to the host box body 10, and the second vertical plate 1233 and the third side plate 22 are formed by the same sheet of paper. The first side plate 123 is formed by folding the first vertical plate 1231, the first connecting top plate 1232 and the second vertical plate 1233 connected in sequence, which can form a buffer space 120 to ensure that the first side plate 123 has good supporting and buffering capacity. Since the weight of the accessories is small, by sharing a sheet of paper for the second vertical plate 1233 and the third side plate 22, the supporting and buffering capacity of the accessories is met, and the material is saved, and the cost is low.

[0065] The width of the first connecting top plate 1232 is the "width of the first side plate 123" mentioned above.

[0066] As shown in Figure 5 and Figure 7As shown, the accessory box body part 20 comprises a second bottom plate 23, the second bottom plate 23 comprises a plurality of support plate body parts 231 arranged at intervals and a partition plate body part 232 connected between two adjacent support plate body parts 231, the partition plate body part 232 is arranged protruding from the support plate body part 231. The partition plate body part 232 can divide the accessory box body part 20 into a plurality of support plate body parts 231, thereby separating a plurality of sub- containing cavities in the accessory box body part 20, respectively for placing different accessories.

[0067] Specifically, as shown in Figure 8 and Figure 4 The second bottom plate 23 is connected to the end of the third side plate 22 away from the first connecting top plate 1232 and extends towards the direction away from the main machine box body part 10, and the accessory box body part 20 further comprises a fourth side plate 24, the fourth side plate 24 is connected to the end of the second bottom plate 23 away from the third side plate 22 and extends towards the direction away from the second bottom plate 23, the fourth side plate 24 is arranged opposite to the third side plate 22, the second fixed plate 34 is connected to the transverse end of the third side plate 22 and has a tongue 341, and the third fixed plate 35 is connected to the transverse end of the fourth side plate 24 and has a socket 351, the socket 351 and the tongue 341 are inserted and matched to realize the fixed connection of the third side plate 22 and the fourth side plate 24, and ensure the structural strength and supporting capacity of the accessory box body part 20.

[0068] Specifically, the accessory box body part 20 can be provided with a plurality of support plate body parts 231 and a plurality of partition plate body parts 232, and the space size of the plurality of support plate body parts 231 can be designed according to different accessory sizes to ensure that each sub-containing cavity is adapted to different accessories.

[0069] As shown in Figure 8 and Figure 11 The top surface of the partition plate body part 232 is flush with the top surface of the accessory box body part 20. When the cover body part 50 is covered on the main machine box body part 10 and the accessory box body part 20, the top surface of the partition plate body part 232 abuts against the cover body part 50, that is, the cover body part 50 can limit the partition plate body part 232, avoiding the partition plate body part 232 from being tilted due to the impact force of the accessories moving around, so that the two adjacent sub-containing cavities are connected, ensuring the separation and support effect of different accessories.

[0070] As shown in Figures 4 to 9As shown, the partition plate body 232 includes two stacked partition plates 2321, which are respectively connected to two adjacent support plate bodies 231. By forming the partition plate body 232 with the two stacked partition plates 2321, the partition plate body 232 can be guaranteed to have a certain support capacity, preventing the partition plate body 232 from tipping over due to the impact of the moving parts, thus avoiding the connection between the two adjacent sub-accommodating cavities; at the same time, the stacked arrangement of the two partition plates 2321 can reduce the space occupied by the partition plate body 232 on the internal space of the accessory box body 20 while realizing the division of the support plate body 231.

[0071] like Figure 11 and Figures 1 to 8 As shown, the side panel 12 includes a second side panel 124 disposed away from the accessory box body 20. The second side panel 124 includes a third upright plate 1241, a second connecting top plate 1242, a fourth upright plate 1243, and a fifth upright plate 1244 connected in sequence. The third upright plate 1241 is connected to the first bottom plate 11 and extends in a direction away from the first bottom plate 11. The second connecting top plate 1242 is connected to the end of the third upright plate 1241 away from the first bottom plate 11 and extends in a direction away from the accessory box body 20. Extending in a certain direction, the fourth upright plate 1243 is connected to the second connecting top plate 1242 and extends towards the first bottom plate 11. The fifth upright plate 1244 is connected to the end of the fourth upright plate 1243 near the first bottom plate 11 and extends towards the second connecting top plate 1242. The supporting liner 2 also includes a cover 50 that is openable and closable above the main unit housing 10 and the accessory housing 20. The cover 50 is connected to the end of the fifth upright plate 1244 near the second connecting top plate 1242. By folding the third upright plate 1241, the second connecting top plate 1242, the fourth upright plate 1243, and the fifth upright plate 1244 in sequence to form the second side plate 124, a buffer space 120 can be formed to ensure the support and buffering capacity of the second side plate 124. The cover portion 50 can limit the main unit and accessories, preventing them from moving around in the support liner 2; the fifth upright plate 1244 can change the extension direction of the cardboard so that the cardboard extends from bottom to top, so that the cover portion 50 can be located above the main unit box portion 10 and the accessory box portion 20, while further increasing the structural strength and cushioning capacity of the second side plate 124.

[0072] The width of the second connecting top plate 1242 is the same as the width of the second side plate 124 mentioned above.

[0073] like Figure 10 and Figure 2As shown, the support liner 2 also includes a cover 50 that is openable and closable above the main unit housing 10 and the accessory housing 20. The cover 50 is connected to the side of the main unit housing 10 away from the accessory housing 20. The cover 50 includes a cover plate 51 and an insertion edge 52 connected to the side of the cover plate 51. The cover 50 can limit the movement of the main unit and accessories within the support liner 2. Specifically, the cover plate 51 covers the upper opening of the main unit housing 10 and the upper opening of the accessory housing 20 to limit the movement of the main unit and accessories of the medical device; the insertion edge 52 is inserted into the gap between the support liner 2 and the outer housing 1, so that the cover 50 can be stably positioned above the main unit housing 10 and the accessory housing 20.

[0074] like Figure 4 As shown, there are insertion gaps between the fixing part 30 and the inner wall of the outer box 1, and between the accessory box part 20 and the inner wall of the outer box 1. The insertion edge 52 can be inserted into the insertion gap, and the width of the insertion gap is greater than or equal to 1 mm and less than or equal to 3 mm. Through the insertion of the insertion edge 52 and the insertion gap, the cover part 50 can stably cover the main unit box part 10 and the accessory box part 20. Compared with other closing and fixing methods such as Velcro, the material cost is lower and the production process is simpler. The width of the insertion gap within the above range can balance the speed of insertion and the firmness of the cover, improving the success rate of aligning the insertion edge 52 with the insertion gap in one go during product packaging. Preferably, the width of the insertion gap can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm.

[0075] like Figure 8 and Figures 3 to 8 As shown, in this embodiment, the height of the fourth side panel 24 is lower than the height of the third side panel 22 to facilitate the user in removing accessories from the accessory box 20. Here, the "interlocking gap between the accessory box 20 and the outer box 1" refers to the gap between the side of the partition plate 232 away from the main unit box 10 and the corresponding side of the lower box 102 of the outer box 1. In specific manufacturing, a portion of the cardboard on the side of the partition plate 232 away from the main unit box 10 (with a cutting width between 1mm and 3mm) can be cut off to form the aforementioned interlocking gap.

[0076] like Figure 10 , Figure 11 and Figures 3 to 8 As shown, a display window 511 corresponding to the main unit housing 10 is provided on the cover plate 51. The medical device has a projection area on the cover plate 51, and the display window 511 is located within the projection area and spaced apart from the outline of the projection area. This arrangement allows the user to see the main unit while preventing the main unit from slipping out of the display window 511 during transportation, thus ensuring the main unit is securely fixed.

[0077] like Figure 10 and ​ As shown, the cover plate 51 is provided with a handle position 512 corresponding to the accessory box body 20. The handle position 512 facilitates the user's operation of opening the cover body 50.
