Description

Technical Field

[0001] This utility model relates to the field of reagent kit technology, specifically to a leak-proof structure and a reagent kit. Background Technology

[0002] Traditional reagent kits often face the following problems during transportation, storage, and use: Simple sealing structure: Sealing relies solely on the physical snap-fit ​​between the lid and body, without a protective layer designed for the gap between the reagent tubes and the box. When the reagent tubes spill due to temperature changes (such as low-temperature expansion during cold chain transportation) or violent shaking (such as manual handling), the liquid can easily seep through the gaps between the side walls and the bottom plate of the box, contaminating the environment or causing cross-contamination of samples. Insufficient structural strength: The box material is mostly lightweight plastic or paper, which is prone to deformation when stacked under weight or subjected to external pressure, leading to reagent tube rupture or sealing layer failure. For example, when transporting reagent kits in stacks, the bottom box may dent due to the pressure from the top, compressing the reagent tubes and causing them to rupture and leak. Therefore, those skilled in the art propose a leak-proof structure and reagent kit solution. Summary of the Invention

[0003] The purpose of this utility model is to provide a leak-proof structure and reagent kit to address the shortcomings mentioned in the background art. To overcome the drawbacks and defects described in the background art, this technical solution includes the following:

[0004] A leak-proof structure includes a leak-proof liner, which includes a reagent tube placement block, four side liner pieces arranged in a ring around the reagent tube placement block, and a support base plate at the bottom of the reagent tube placement block. Nine to twelve reagent tubes are inserted inside the reagent tube placement block. A lid liner piece is provided at the rear of the reagent tube placement block, and two side cover liner pieces are provided on the top left and right sides of the reagent tube placement block.

[0005] As a preferred embodiment of this utility model: the four sides of the outer surface of the reagent tube placement block are fixedly connected to the middle section of the inner surface of the side liner by an adhesive.

[0006] As a preferred embodiment of this utility model, the outer surface of the supporting base plate and the four side walls are respectively fixedly connected to the bottom section of the inner surface of the side lining piece by an adhesive.

[0007] As a preferred embodiment of this utility model, the reagent tube placement block has 9-12 insertion holes arranged in a rectangular array inside, for inserting reagent tubes into the reagent tube placement block.

[0008] As a preferred embodiment of this utility model: the upper surface of the supporting base plate is provided with 9-12 circular grooves arranged in a rectangular array, and the bottom end face of the reagent tube is respectively coupled to the interior of the circular groove.

[0009] As a preferred embodiment of this utility model, the side lining sheet, the side cover lining sheet, and the box lid lining sheet are all made of plastic or polyurea waterproof fabric.

[0010] A reagent kit is also provided, which includes a box body, a box cover fixedly connected to the upper surface of the back of the box body, and a top cover plate fixedly connected to the end of the box cover, and side covers are fixedly connected to the left and right sides of the top surface of the box body.

[0011] As a preferred embodiment of this utility model: the four sides of the inner cavity of the box body are fixedly connected to the outer surface of the side lining sheet by adhesive, the inner surface of the side cover is fixedly connected to the outer surface of the side cover lining sheet by adhesive, and the inner surface of the box cover is fixedly connected to the outer surface of the box cover lining sheet by adhesive.

[0012] As a preferred embodiment of this utility model, the bottom surface of the inner cavity of the box body is fixedly connected to the bottom surface of the supporting base plate by an adhesive.

[0013] As a preferred embodiment of this utility model, a nameplate is attached to the front end face of the box body.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This solution achieves multiple layers of protection and structural reinforcement by adding a leak-proof liner inside the reagent kit. The leak-proof liner, through the combined action of side liners, a supporting base plate, side cover liners, and lid liners, forms a three-dimensional sealing layer inside the kit, completely enclosing the reagent tube placement area. When reagent tubes expand due to environmental changes or are subjected to bumps and shaking, causing internal liquid to spill, the sealing layer effectively traps the liquid, preventing it from seeping into the kit's gaps and leaking into the external environment. Simultaneously, the leak-proof liner is rigidly connected to various parts of the kit via adhesive. Its high deformation resistance, achieved through plastic or polyurea material, provides structural support to the kit, enhancing the toughness and rigidity of the side walls and bottom, dispersing external compressive stress, and preventing the kit from deforming and compressing the reagent tubes.

[0022] To provide a clearer explanation and description of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.

[0023] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of each embodiment. Specific details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures. The disclosures of various publications, patents, and published patent specifications cited herein are incorporated herein by reference in their entirety. The technical solutions of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0024] Example 1: The leak-proof inner liner 1 consists of a reagent tube placement block 11, four side inner liner pieces 12, and a supporting base plate 14. The reagent tube placement block 11 is a rectangular block with 12 rectangular arrayed insertion holes 15 inside, each insertion hole 15 having an inner diameter adapted to the outer wall of the reagent tube 16. The upper surface of the supporting base plate 14 has 12 circular grooves 13, corresponding one-to-one with the insertion holes 15. The four side inner liner pieces 12 are fixed to the middle sections of the four sides of the reagent tube placement block 11 and the bottom sections of the four sides of the supporting base plate 14 respectively with adhesive, forming an overall frame. The reagent kit body 21 is a top-opening container made of plastic, with its inner cavity sidewalls fixedly connected to the outer side of the side inner liner pieces 12 with adhesive, and the bottom of the inner cavity bonded to the bottom of the supporting base plate 14. The lid 22 is hinged to the box body 21 at the rear, and the inner surface of the lid is bonded to the inner liner 18 with adhesive. The side covers 24 are hinged to the top left and right sides of the box body 21 respectively, and the inner surface of the side covers is bonded to the inner liner 17. The top cover insert 23 is a protruding buckle at the front end of the lid 22, used to insert into the groove on the front side of the box body 21 for locking. The reagent tube 16 is inserted into the insertion hole 15, and the bottom is embedded in the circular groove 13 for positioning. After the lid 22 and the side covers 24 are closed, the inner liners 12 on the side, 17 on the side, and 18 on the lid form a sealing layer to prevent liquid leakage.

[0025] Example 2: The side lining 12, side cover lining 17, and lid lining 18 are all made of polyurea waterproof fabric, connected to the reagent tube placement block 11, the supporting base plate 14, and the box body components by hot melt adhesive. The reagent tube placement block 11 is changed to a honeycomb structure to reduce material usage, and has 9 insertion holes 15 inside. The supporting base plate 14 has 9 corresponding circular grooves 13. The box body 21 is made of lightweight polypropylene material, with the thickness reduced from 2mm to 1.5mm. The side cover 24 and the lid 22 use elastic plastic hinges to reduce the weight of the mechanical structure. The nameplate 25 is directly printed on the front of the box body 21 using a waterproof sticker, avoiding additional adhesive parts. The operation process is the same as in Example 1, but the polyurea waterproof fabric lining can be bent and folded for easy storage and transportation. The honeycomb reagent tube placement block 11 reduces the overall weight while ensuring strength.

[0026] Example 3: The reagent tube placement block 11 is enlarged, with 12 internal insertion holes 15 arranged in a double-layered staggered pattern. The diameter of the insertion holes 15 is increased to accommodate reagent tubes 16 of different sizes. The thickness of the supporting base plate 14 is increased to 5mm, and the depth of the circular groove 13 is deepened to enhance support stability. The height of the box body 21 is increased by 30%, and longitudinal reinforcing ribs are provided on the inner wall of the cavity, which are fixed to the side lining 12 through multi-point bonding. The width of the side cover 24 is extended to cover the top edge of the reagent tube placement block 11, and the side cover lining 17 extends above the insertion holes 15 to form a protective awning. The double-layered insertion holes 15 support the storage of different types of reagents in separate areas. When the side cover 24 is closed, the protective awning covers the top of the reagent tubes 16 to prevent liquid from overflowing.

[0027] Example 4: The reagent tube placement block 11 and the supporting base plate 14 are integrally injection molded. The number of insertion holes 15 is reduced to 9, and the thickness of the side inner liner 12 is reduced to 0.5mm, using a foldable plastic sheet. The side cover inner liner 17 and the box lid inner liner 18 are integrated into a single-piece structure, and opening and closing are achieved through creases. The box body 21 is a flat cuboid, and the top opening width is reduced to only allow the reagent tube placement block 11 to be inserted. The box lid 22 and the side cover 24 are combined into a single-sided flip-top structure, and the top cover insert plate 23 is replaced with a magnetic snap fastener. The nameplate 25 is laser-engraved on the top surface of the box body 21. The reagent tube 16 is inserted horizontally into the insertion hole 15, and after folding the side inner liner 12, the box lid 22 is directly snapped shut, and the magnetic snap fastener automatically locks, suitable for outdoor rapid operation scenarios.

[0028] Example 5: The reagent tube placement block 11 is designed as a detachable insert plate, connected to the supporting base plate 14 via slots. The side liner 12 is divided into four independent units, each corresponding to one side of the reagent tube placement block 11, and connected to the inner wall of the box body 21 via Velcro. The box body 21 is an open frame with multiple sets of slots in the inner cavity, allowing for the simultaneous installation of multiple leak-proof liners 1. The box lid 22 and side cover 24 are made of transparent acrylic, with replaceable liner slots on the inside, supporting quick replacement of liners of different materials. Different specifications of leak-proof liner 1 can be selected according to the reagent type and freely combined inside the box body 21 via slots. The transparent box lid 22 facilitates observation of the internal status, and the entire structure does not need to be disassembled when replacing the liner.

[0029] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0030] Insert the reagent tube 16 vertically into the insertion hole 15 of the reagent tube placement block 11. The bottom of the reagent tube is embedded in the circular groove 13 of the supporting base plate 14, forming a dual positioning of bottom plane support and side wall hole limitation, ensuring that the reagent tube is upright and does not directly contact the box body. Flip the box cover 22 so that the inner liner 18 of the box cover fits against the back of the reagent tube placement block 11. After the side cover 24 is closed, its inner liner 17 covers the top left and right sides of the reagent tube placement block 11. At the same time, the inner liner 12 of the side cover wraps around the inner wall of the box body 21. The four of them form a continuous sealing layer through surface contact, trapping the liquid in the reagent tube that may be spilled due to temperature changes or shaking during handling, and preventing the liquid from seeping out along the gap between the side wall and the base plate of the box body. During handling, if the reagent kit is subjected to lateral compression or vertical stacking pressure, the side inner liner 12 and the supporting base plate 14 serve as a rigid skeleton and are fixedly connected to the inner wall and bottom of the box body 21 by adhesive, dispersing the concentrated stress to the overall structure of the box body, suppressing the side wall of the box body from denting or the base plate from deforming, and preventing the reagent tube from being crushed due to local deformation of the box body.

[0031] If the reagent kit is accidentally dropped or impacted, the side liner 12 and the lid liner 18 cushion the instantaneous impact force through material elasticity, preventing gaps from forming between the sealing layer and the reagent tube contact surface due to rigid collision, thus maintaining leak-proof performance. At the same time, the circular groove 13 supporting the base plate 14 restricts the lateral displacement of the bottom of the reagent tube, reducing the risk of the tube tipping over. After releasing the latch between the top cover insert 23 and the box body 21, the lid 22 causes the lid liner 18 to detach from the rear side of the reagent tube placement block 11. After the side cover 24 is opened, the side cover liner 17 exposes the top of the reagent tube, allowing the operator to directly pick up and place the reagent tube. During this process, the side liner 12 remains connected to the inner wall of the box body 21, maintaining the integrity of the internal sealing structure. When the reagent kit is not in use, the leak-proof inner liner 1 maintains the cubic shape of the box body 21 through the support of the side inner liner 12 and the supporting base plate 14, preventing the box body from collapsing or the inner wall from wrinkling due to long-term placement, ensuring the flatness of the contact surface between the sealing layer and the reagent tube, and providing continuous protection for the reagent tube.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
