[0030] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0031] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure belongs.

The terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0032] To facilitate the understanding of the packaging box provided in the embodiment of the present application, its application scenario will be described first. The packaging box provided in the embodiment of the present application can be used to hold biochips.

[0033] With the increasing development of biotechnology, the combination of electronic technology and biotechnology has given birth to biochips. A large number of biomolecular probes are integrated on the biochips. These biomolecular probes are very precise. Once damaged during storage and transportation, the functions of the biochips will be directly affected. Therefore, during the storage and transportation of biochips, there are extremely high requirements for the shock absorption and protection, cleanliness and humidity of the packaging.

[0034] In general, for existing biochip packaging boxes, the biochips are directly placed in the packaging boxes, and then bagged desiccants are placed in the packaging boxes to keep the storage and transportation environment of the biochips dry. However, when the existing biochip packaging boxes are being transported or moved, on the one hand, the inner wall of the packaging box is prone to scratching the biochips, and on the other hand, the bagged desiccants in the packaging box are prone to rubbing against the biochips. Whether it is the inner wall of the packaging box or the bagged desiccants rubbing against the biochips, it is easy to cause damage to the biomolecular probes, and then cause structural damage to the biochips, affecting the functions of the biochips.

[0035] Therefore, this application provides a packaging box, aiming to improve the problem that the existing packaging boxes are prone to cause structural damage to biochips by improving the structure of the packaging box. The following specifically introduces the packaging box provided by this application with reference to the accompanying drawings.

[0036] First, introduce the basic structures of the biochip and the bagged desiccant. Refer to Figure 1 , Figure 1 which is a schematic diagram of the biochip structure. The biochip 1 includes a glass slide 11 and a frame 12. Among them, the biomolecular probes are all located on the glass slide 11. Therefore, to protect the biochip 1 from scratching with the packaging box 3 or the bagged desiccant 2, it mainly lies in protecting the glass slide 11 from scratching with the packaging box 3 or the bagged desiccant 2. Refer to Figure 2 , Figure 2 which is a schematic diagram of the bagged desiccant structure. As shown in Figure 2 , the bagged desiccant 2 is generally in the shape of a pocket, and the inside is filled with a hygroscopic material. The opposite ends of the bagged desiccant 2 are heat-sealed ends 21. The bagged desiccant 2 can be sealed by heat-sealing to prevent the hygroscopic material from spilling out. The whole of the bagged desiccant 2 is relatively soft, but the heat-sealed ends 21 at both ends are in a relatively hard state due to the heat-sealing process.

[0037] Refer to Figure 3 and Figure 4 , Figure 3 which is a schematic diagram of the whole packaging box in the embodiment of this application, Figure 4 which is a schematic diagram of the box body in the embodiment of this application. The packaging box 3 provided by this application includes a box body 31. The box body 31 serves as the main space for accommodating the biochip 1. A chip slot 311 for placing the biochip 1 is provided in the box body 31. The opening of the chip slot 311 is the entrance for placing the biochip 1 into the chip slot 311. To facilitate the understanding of the packaging box 3 in the embodiment of this application, it is defined here that when the packaging box 3 is placed flat, the direction in which the biochip 1 is placed into the chip slot 311 from the opening of the chip slot 311 is the vertical direction. In Figure 3 or Figure 4In the figure, the defined vertical direction is indicated by arrows for reference. When the chip slot 311 is specifically set, the slot shape of the chip slot 311 can be determined according to the shape of the biochip 1, so that after the biochip 1 is vertically placed in the chip slot 311, the side wall of the chip slot 311 can limit the shaking of the biochip 1 on the horizontal plane perpendicular to the vertical direction. For example Figure 3 as well as Figure 4 As shown in FIG. 1 , the shape of the biochip 1 on the horizontal plane is approximately rectangular, and the corresponding chip slot 311 is also an approximately rectangular slot so as to better match the biochip 1 .

[0038] Optionally, in a specific implementation, an avoidance structure may be provided at the edge of the chip slot 311 to facilitate the taking and placing of the biochip 1. Figure 4 , the edge of the chip slot 311 has at least one avoidance groove 312. Specifically, in order to better limit the shaking of the biochip 1 on the horizontal plane, the opening of the chip slot 311 matches the shape of the biochip 1, and at a set position, a part of the side wall of the chip slot 311 avoids in the direction away from the edge of the biochip 1 to form the avoidance groove 312. By providing the avoidance groove 312, it is convenient for the operator to move the biochip 1 when placing or removing the biochip 1. As an example, Figure 4 The number of the avoidance grooves 312 shown is two, and they are respectively located on the two relatively long side walls of the chip slot 311, so that the operator can pinch or use tools to clamp the biochip 1 from the two relatively long sides of the biochip 1 to perform operations. Of course, in other possible implementations, the number of the avoidance grooves 312 can also be four, six, etc. For example, the avoidance grooves 312 are also provided on the two relatively short side walls of the chip slot 311, so as to provide a more flexible operating space for the operator.

[0039] refer to Figure 4 , a limiting protrusion 313 is also provided on the side wall of the chip slot 311, and the limiting protrusion 313 is used to cooperate with the bottom wall of the chip slot 311 and clamp the frame 12 of the biochip 1. Specifically, the limiting protrusion 313 is constructed to protrude from the side wall of the chip slot 311 to the center of the chip slot 311, and in the vertical direction, there is a certain interval between the limiting protrusion 313 and the bottom wall of the chip slot 311. After the biochip 1 is placed in the chip slot 311, the frame 12 of the biochip 1 is clamped between the limiting protrusion 313 and the bottom wall of the chip slot 311. The biochip 1 is clamped between the limiting protrusion 313 and the bottom wall of the chip slot 311, which can limit the shaking of the biochip 1 in the vertical direction.

[0040] The limiting protrusion 313 restricts the movement of the biochip 1 in the vertical direction, and the side wall of the chip slot 311 can restrict the movement of the biochip 1 in the horizontal plane perpendicular to the vertical direction. The cooperation between the limiting protrusion 313 and the side wall of the chip slot 311 can completely confine the biochip 1 within the chip slot 311, thereby reducing the shaking of the biochip 1 and the risk of scratching the packaging box 3 due to the shaking of the biochip 1. When specifically inserting the biochip 1, the frame 12 of the biochip 1 can be pressed downward in the vertical direction, causing the limiting protrusion 313 to deform, so that the biochip 1 is clamped between the limiting protrusion 313 and the bottom of the slot, and the operation is relatively convenient. Similarly, when removing the biochip 1 from the packaging box 3, the biochip 1 can be pinched through the avoidance slot 312 or clamped with a tool, and then upward force is applied to deform the limiting protrusion 313, and the biochip 1 can be taken out.

[0041] Optionally, the number of the limiting protrusions 313 is at least two, and at least two limiting protrusions 313 are arranged at annular intervals. By setting at least two limiting protrusions 313 to jointly clamp the biochip 1, the stability of clamping and fixing the biochip 1 can be improved, and the risk of the biochip 1 shaking in the vertical direction can be further reduced. In specific implementation, two, three, four, five or more limiting protrusions 313 can be arranged circumferentially along the side wall of the chip slot 311. And when setting two or more limiting protrusions 313, the limiting protrusions 313 can be arranged as evenly as possible along the side wall of the chip slot 311 to further improve the stability of clamping and fixing the biochip 1. As a specific example, as Figure 4 shown, the box body 31 is provided with six limiting protrusions 313, one limiting protrusion 313 is respectively arranged on the opposite two short side walls of the chip slot 311, and two limiting protrusions 313 are respectively arranged on the opposite two long side walls. In specific application, the six limiting protrusions 313 can stably clamp the biochip 1 and reduce the risk of the biochip 1 shaking.

[0042] Refer to Figure 5 , Figure 5 which is the schematic cross-sectional view of the box body in the embodiment of the present application. As shown in Figure 5 , after the biochip 1 is placed in the chip slot 311, the bottom wall of the chip slot 311 avoids the glass slide 11 of the biochip 1. Specifically, it can be configured that the part of the bottom wall of the chip slot 311 corresponding to the glass slide 11 sinks in the vertical direction, so that a avoidance space is formed between the bottom wall of the chip slot 311 and the glass slide 11. By setting the bottom wall of the chip slot 311 to avoid the glass slide 11, the risk of scratching between the bottom wall of the chip slot 311 and the glass slide 11 caused by the deformation of the box body 31 during transportation can be reduced, thereby further protecting the biochip 1.

[0043] To reduce the risk of scratching between the biochip 1 and the bagged desiccant 2, the cartridge body 31 also has a structure for fixing the bagged desiccant 2. Referring together to Figure 3 , Figure 4 and Figure 5 , a desiccant groove 314 for holding the bagged desiccant 2 is provided at the bottom of the chip groove 311. Specifically, the form of the desiccant groove 314 can be that the bottom wall of the chip groove 311 sinks further away from the biochip 1 in the vertical direction, so as to form a desiccant groove 314 below the place where the biochip 1 is placed. Similar to the chip groove 311, the opening shape of the desiccant groove 314 matches the shape of the bagged desiccant 2, so that when the bagged desiccant 2 is placed into the desiccant groove 314, the side wall of the desiccant groove 314 can restrict the bagged desiccant 2 and reduce the risk of the bagged desiccant 2 shaking on the horizontal plane.

[0044] A stepped surface 315 for supporting the bagged desiccant 2 is provided in the desiccant groove 314. When the bagged desiccant 2 is placed into the desiccant groove 314, the heat-sealed end 21 of the bagged desiccant 2 abuts against the stepped surface 315, and in the vertical direction, upward support is provided for the bagged desiccant 2 through the abutment of the heat-sealed end 21 and the stepped surface 315. In addition, when the bagged desiccant 2 is placed in the desiccant groove 314, the bagged desiccant 2 also abuts against the biochip 1. Through the abutment of the heat-sealed end 21 and the stepped surface 315 and the abutment of the bagged desiccant 2 and the biochip 1, a clamping effect is formed on the bagged desiccant 2 in the vertical direction, thereby restricting the shaking of the bagged desiccant 2 in the vertical direction. It should be understood that the surface texture of the bagged desiccant 2 itself is relatively soft. Therefore, when the bagged desiccant 2 directly abuts against the biochip 1, if the bagged desiccant 2 does not shake strongly, it will not cause strong scratching with the biochip 1 resulting in damage to the biochip 1. Through the clamping of the stepped surface 315 and the biochip 1 in the vertical direction and the restriction of the side wall of the desiccant groove 314 in the horizontal plane direction, the shaking of the bagged desiccant 2 can be restricted, the risk of scratching between the bagged desiccant 2 and the biochip 1 can be reduced, and the purpose of protecting the biochip 1 can be achieved.

[0045] Optionally, referring to Figure 5 , when specifically setting the desiccant groove 314, the depth of the desiccant groove 314 can be set to satisfy: when the bagged desiccant 2 is placed in the desiccant groove 314, there is a gap between the bagged desiccant 2 and the bottom of the desiccant groove 314. That is, in the vertical direction, the bagged desiccant 2 is supported by the abutment of the heat-sealed end 21 and the stepped surface 315 and is in a relatively suspended state from the bottom of the desiccant groove 314. Setting such a gap can reduce the risk of the bottom of the desiccant groove 314 squeezing the bagged desiccant 2 due to the deformation of the cartridge body 31 during transportation, resulting in scratching between the bagged desiccant 2 and the glass slide 11, thereby further protecting the biochip 1.

[0046] Optionally, referring to Figure 3 , when specifically setting the desiccant tank 314, the number of desiccant tanks 314 can be set to at least two, and at least two desiccant tanks 314 are arranged at intervals. The number of bagged desiccants 2 corresponding to the number of desiccant tanks 314 is also at least two. By setting two or more desiccant tanks 314, on the premise that the total amount of the hygroscopic material remains unchanged, the size of a single bagged desiccant 2 can be reduced. The smaller the volume and weight of a single bagged desiccant 2, the more stable the clamping of the bagged desiccant 2 when the heat-sealed end 21 abuts against the step surface 315 and the bagged desiccant 2 abuts against the biochip 1, thereby further reducing the risk of the bagged desiccant 2 shaking and further protecting the biochip 1. And setting two or more desiccant tanks 314 arranged at intervals can separate two or more bagged desiccants 2 in the horizontal plane direction, reducing the risk of the bagged desiccant 2 shaking in the horizontal plane direction. Of course, for separating two or more bagged desiccants 2 in the horizontal plane direction, in specific implementation, in addition to setting two or more desiccant tanks 314, a separation structure can also be set in the same desiccant tank 314. As an example, as Figure 3 shown, the number of desiccant tanks 314 is two. Of course, in other optional implementation manners, the number of desiccant tanks 314 can also be three, four, five, etc.

[0047] In the above technical solution, by providing the limiting protrusion 313 on the side wall of the chip slot 311 and clamping the border 12 of the biochip 1 with the bottom wall of the chip slot 311, the shaking of the biochip 1 in the packaging box 3 and the scratching with the inner wall of the packaging box 3 can be reduced; the packaging box 3 also limits the bagged desiccant 2 by providing the desiccant tank 314, thereby reducing the scratching with the biochip 1 due to the shaking of the desiccant; by reducing the risk of the biochip 1 scratching with the inner wall of the packaging box 3 and reducing the risk of the biochip 1 scratching with the bagged desiccant 2, the problem that the existing packaging box 3 is likely to cause structural damage to the biochip 1 can be improved.

[0048] As an optional implementation manner, in specific implementation, the packaging box 3 further includes a box cover 32 for protecting the side of the glass slide 11 away from the bottom wall of the chip slot 311. Referring together to Figure 3 and Figure 6 , Figure 6 is the schematic diagram of the box cover in the embodiment of the present application. The box cover 32 cooperates with the box body 31. The box cover 32 can be snap-fitted and fixed with the box body 31 to close the chip slot 311 containing the biochip 1, thereby covering the side of the glass slide 11 away from the bottom wall of the chip slot 311 and protecting the glass slide 11.

[0049] Referring to Figure 7 , Figure 7Schematic diagram of the lid and the body of the present application embodiment being fastened. Optionally, the lid 32 has a first fastening portion 321, and the body 31 has a second fastening portion 316. When the lid 32 and the body 31 are fastened, the first fastening portion 321 and the second fastening portion 316 are fastened and fixed. By providing the first fastening portion 321 and the second fastening portion 316, the fastening stability between the lid 32 and the body 31 can be improved, the risk of the lid 32 detaching from the body 31 during transportation can be reduced, and thus the biochip 1 can be better protected.

[0050] In specific implementation, the second fastening portion 316 can be Figure 7 in the shape of the wedge-shaped concave portion shown, and correspondingly, the first fastening portion 321 can be Figure 7 in the shape of the wedge-shaped concave portion shown. When fastening the lid 32, the wedge-shaped convex portion is inserted into the wedge-shaped concave portion, thereby realizing the fastening and fixing of the lid 32 and the body 31. Of course, in other alternative implementation manners, the first fastening portion 321 and the second fastening portion 316 can also be in other forms, which will not be elaborated here.

[0051] Continue to refer to Figure 3 and Figure 6 , in specific implementation, the lid 32 is further provided with an upper cover protrusion 322. The upper cover protrusion 322 is located on the side of the lid 32 facing the biochip 1, and the upper cover protrusion 322 is opposite to the border 12 of the biochip 1. When the lid 32 and the body 31 are fastened, the upper cover protrusion 322 abuts against the border 12 of the biochip 1. By providing the upper cover protrusion 322 that abuts against the border 12 of the biochip 1, it can assist in pressing and fixing the biochip 1 in the vertical direction, thereby reducing the risk of the biochip 1 shaking in the packaging box 3, and further assisting in protecting the biochip 1. Specifically, when setting the upper cover protrusion 322, the upper cover protrusion 322 can be arranged along the border 12 of the biochip 1 so as to have better stability when the upper cover protrusion 322 abuts against the biochip 1. For example Figure 3 the upper cover protrusion 322 shown is arranged in a ring along the border 12 of the biochip 1 and is not continuous at the corners. Such an arrangement can, on the one hand, reduce the production and processing difficulty, and on the other hand, the intervals between the upper cover protrusions 322 can also balance the air pressure, avoiding the generation of pressure differences on both sides of the upper cover protrusion 322 after the upper cover protrusion 322 abuts against the biochip 1, and reducing the risk of the upper cover protrusion 322 bringing out the biochip 1 when opening the lid.

[0052] Refer to together Figure 6 and Figure 7, Optionally, when specifically setting the lid 32, the lid 32 is further provided with a safety groove 323, and the safety groove 323 is located at a position opposite to the glass slide 11. When the lid 32 is buckled with the box body 31, the safety groove 323 is opposite to the glass slide 11 of the biochip 1, and there is a certain interval between the bottom of the safety groove 323 and the glass slide 11 of the biochip 1. By setting the safety groove 323, the risk of scratching between the lid 32 and the glass slide 11 due to the deformation of the lid 32 during transportation can be reduced, thereby better protecting the biochip 1.

[0053] Refer to together Figure 3 and Figure 8 , Figure 8 is a schematic diagram of the first extension edge and the second extension edge in the embodiment of the present application. As an alternative implementation, the lid 32 is provided with a first extension edge 324, and the first extension edge 324 is formed by the material of the lid 32 protruding outward along the edge of the lid 32 towards the outside of the packaging box 3; the box body 31 is provided with a second extension edge 317, and the second extension edge 317 is formed by the material of the box body 31 protruding outward along the edge of the box body 31 towards the outside of the packaging box 3. And when the lid 32 is buckled with the box body 31, the first extension edge 324 and the second extension edge 317 are located on the same side and at least partially do not coincide. Among them, at least partially not coinciding means that the first extension edge 324 and the second extension edge 317 partially coincide, or the first extension edge 324 and the second extension edge 317 do not coincide at all. When the biochip 1 is to be taken out, the lid 32 needs to be opened first. Since the box body 31 and the lid 32 are buckled and fixed, a certain force must be applied to separate the lid 32 from the box body 31, and the first extension edge 324 and the second extension edge 317 can be used as the force application points. And because the first extension edge 324 and the second extension edge 317 at least partially do not coincide, it is convenient to apply opposite-direction acting forces to the first extension edge 324 and the second extension edge 317 simultaneously at the non-coinciding part of the first extension edge 324 and the second extension edge 317, so as to separate the lid 32 from the box body 31. By setting the first extension edge 324 and the second extension edge 317 that are at least not completely coincident, the convenience of opening the packaging box 3 can be improved.

[0054] As an alternative implementation, continue to refer to Figure 3 , when specifically producing the packaging box 3, the lid 32 and the box body 31 can be integrally formed by thermoforming. By adopting the method of integral thermoforming, the production efficiency of the packaging box 3 can be improved. On the other hand, the integrally thermoformed lid 32 and box body 31 can also ensure that one box body 31 is matched with one lid 32, which is convenient for the supporting production of the lid 32 and the box body 31, and further reduces the difficulty of warehouse inventory.

[0055] When specifically integrally manufacturing the lid 32 and the box body 31, the same-side edges of the lid 32 and the box body 31 can be set to be connected, and creases can be pressed at the connection between the lid 32 and the box body 31 to facilitate the folding of the lid 32. Moreover, the first extension edge 324 can be set on the side edge of the lid 32 opposite to the connection between the lid 32 and the box body 31, that is, the first extension edge 324 and the crease can be set on opposite sides, and the second extension edge 317 cooperating therewith is also on the opposite side of the crease, so as to apply uniform torque to the lid 32 and the box body 31 when applying force through the first extension edge 324 and the second extension edge 317, and improve the stability of the process of opening the lid.

[0056] One or more embodiments of this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments of this specification shall be included within the protection scope of this disclosure.

[0057] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed by this application can easily think of changes or substitutions, which should all be covered within the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claims.
