Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a double-sided pipette tip box. Background Technology

[0002] In many scientific research fields such as biology, chemistry, and medicine, pipettes are key instruments for accurately measuring liquids, and the pipette tips used with them are used in large quantities and need to be properly stored. Pipette tip boxes have emerged as an essential consumable storage tool in laboratories, ensuring the cleanliness and neat storage of pipette tips for easy access by researchers.

[0003] A search revealed Chinese patent CN220501867U, which discloses a pipette tip loading auxiliary device. The device includes: an arrangement box with multiple rows of arrangement slots; a housing with multiple through holes corresponding to the arrangement slots at the bottom; a mounting body inside the housing; and multiple insertion posts passing through the through holes at the bottom of the mounting body. The insertion posts are slidably connected to the through holes, with the outer diameter of the insertion posts larger than the inner diameter of the large end portion of the pipette tip, and the diameter of the through holes smaller than the outer diameter of the large end portion of the pipette tip. A handle is located at the top of the mounting body, and the handle has a spring return mechanism connected to the housing. The spring return mechanism controls the vertical movement of the housing. This pipette tip loading auxiliary device, by incorporating an arrangement box for quickly arranging pipette tips and a moving loading device, enables fast and efficient pipette tip loading. It offers high flexibility, adaptable to both overall and partial loading, and features a simple structure and low cost.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Most existing pipette tip boxes use a simple single-layer design, lacking a robust internal support structure for the pipette tips. Tips placed haphazardly inside are easily damaged by collisions during handling and movement, increasing the cost of experimental consumables and potentially impacting experimental progress and accuracy due to frequent tip replacements. Furthermore, the single-layer structure has low space utilization, failing to meet the laboratory's storage needs for large quantities of tips, requiring frequent replenishment by researchers, which is time-consuming. In addition, existing tip boxes lack effective protection and observation designs, failing to prevent tips from getting damp or contaminated with bacteria, and hindering researchers from quickly checking the remaining quantity and storage status of tips, thus impeding efficient experimental operations. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a double-sided pipette tip box, which employs a double-layer frame support plate. Its unique upper and lower mounting plates and supporting bottom ring structure design provide stable support for the pipette tips, preventing the tips from shaking and colliding inside the box, greatly reducing the risk of tip damage and extending the tip's service life.

[0007] The technical solution to achieve the purpose of this utility model is: a double-sided pipette tip box, including an arrangement box body and a top cover plate adapted to and matched with the top opening of the arrangement box body, wherein multiple sets of pipette tips are placed inside the arrangement box body, and further includes;

[0008] A double-layer frame support plate, wherein the double-layer frame support plate is inserted into the inner bottom surface of the arrangement box body from the top opening of the arrangement box body and snapped in place;

[0009] The double-layer frame support plate includes upper and lower mounting plates and a support bottom ring. A connecting plate is connected to one of the bottom layers of the mounting plate and the support bottom ring. A positioning hole is opened on the support bottom ring. A docking post corresponding to the positioning hole is installed on the inner bottom surface of the arrangement box body. A protective sleeve assembly for storing pipette tips is provided between the mounting plate and the support bottom ring. The protective sleeve assembly is arranged in a row horizontally on the mounting plate, with at least four in each row.

[0010] A locking assembly is disposed on two adjacent outer sides of the arrangement box body and the top cover plate.

[0011] In some embodiments, the top of the mounting plate is provided with at least three rows of plastic partitions for isolating multiple sets of protective sleeve assemblies arranged laterally.

[0012] In some embodiments, the protective sleeve assembly includes a limiting sleeve connected to the bottom of the mounting plate, with the upper end of the limiting sleeve extending to the upper surface of the mounting plate, and the bottom of the pipette tip inserted into the top opening of the corresponding limiting sleeve.

[0013] In some embodiments, each of the limiting sleeves has equally spaced perforated holes on its outer side, and transparent observation sheets are installed on both sides of the arrangement box body.

[0014] In some embodiments, the locking assembly includes a first connecting plate connected to the outside of the top cover plate and a second connecting plate installed on the upper side of the outer side of the arranging box body. The first connecting plate has an L-shaped structure and the connecting hole corresponds vertically to the inner side of the first connecting plate. The first connecting plate has a connecting hole, and the second connecting plate has a protrusion that engages with the inside of the connecting hole.

[0015] Compared with existing technologies, the significant advantages of this invention are:

[0016] Firstly, this utility model employs a double-layer frame support plate. Its unique upper and lower mounting plates and supporting bottom ring structure design, combined with the docking posts on the bottom surface of the arrangement box body and the positioning holes on the supporting bottom ring, achieve precise and stable locking. On the one hand, it provides stable support for the pipette tips, preventing the tips from shaking and colliding inside the box, greatly reducing the risk of tip damage and extending the tip's service life. On the other hand, the double-layer structure effectively increases space utilization, allowing for the storage of a larger number of pipette tips, meeting the needs of laboratories using a large number of tips, and improving practicality.

[0017] Secondly, the protective sleeve assembly equipped with this utility model features a limiting soft sleeve connected to the bottom of the mounting plate and extending to its upper surface. The pipette tip is inserted into the top opening of the limiting soft sleeve, which not only provides precise positioning and protection for the pipette tip, preventing it from tipping over or rolling off, but also allows for air circulation through the perforated holes on the outside of the limiting soft sleeve, keeping the pipette tip dry and reducing bacterial growth. Simultaneously, combined with the transparent observation films on both sides of the arrangement box body, users can clearly observe the placement of the pipette tips at any time, facilitating quantity counting and checking the condition of the pipette tips, thus improving the convenience and accuracy of experimental operations.

[0018] This invention solves the problems of existing pipette tip boxes having a simple structure, failing to effectively protect and support the pipette tips, easily causing damage or loss of the tips, low space utilization, and inconvenience in observing the condition of the tips.

[0027] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0028] This utility model provides an improved double-sided pipette tip holder. The technical solution of this utility model is as follows:

[0029] like Figure 1 - Figure 5 As shown, a double-sided pipette tip box includes a box body 1 and a top cover plate 2 that is adapted to and connected to the top opening of the box body 1. The box body 1 contains multiple sets of pipette tips 3, and also includes a double-layer frame support plate, a docking post 102, a protective sleeve assembly, and a locking assembly inside the box body 1.

[0030] The double-layer frame support plate is inserted into the inner bottom surface of the arrangement box body 1 from the top opening of the arrangement box body 1 and snapped in place.

[0031] The double-layer frame support plate includes upper and lower mounting plates 4 and a supporting bottom ring 401. Both the mounting plates 4 and the supporting bottom ring 401 are made of elastic material with an annular structure. A connecting plate 402 is connected to one of the bottom layers of the mounting plates 4 and the supporting bottom ring 401. The supporting bottom ring 401 has positioning holes 403. The inner bottom surface of the arrangement box body 1 is equipped with docking posts 102 that correspond to the positioning holes 403. A protective sleeve assembly for storing pipette tips 3 is provided between the mounting plates 4 and the supporting bottom ring 401. The protective sleeve assemblies are arranged in a horizontal row on the mounting plates 4, with at least four in each row. The locking assembly is provided on the two adjacent outer sides of the arrangement box body 1 and the top cover plate 2. This tight snap-fit ​​structure allows the double-layer frame support plate to be stably placed inside the arrangement box body 1, providing a reliable support foundation for the pipette tips 3. The alignment of the positioning hole 403 with the docking post 102 ensures the precise installation position of the double-layer frame support plate, preventing it from shaking or shifting within the box. This ensures that the pipette tips 3 remain stable, avoiding collisions and damage, improving the safety of tip storage, and extending tip lifespan. Simultaneously, the double-layer structure design increases space utilization, allowing for the storage of a larger number of pipette tips 3, meeting the needs of frequent tip use in laboratories.

[0032] like Figure 2 and Figure 3 As shown, in one embodiment, the top of the mounting plate 4 is provided with at least three rows of plastic partitions 5 for isolating multiple sets of protective sleeve assemblies arranged laterally; the mounting plate 4 is provided with plastic partitions 5 for separating pipette tips 3.

[0033] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the protective sleeve assembly includes a limiting soft sleeve 404 connected to the bottom of the mounting plate 4, with the upper end of the limiting soft sleeve 404 extending to the upper surface of the mounting plate 4. The bottom of the pipette tip 3 is inserted into the top opening of the corresponding limiting soft sleeve 404. Each limiting soft sleeve 404 has equally spaced perforated holes on its outer side, and transparent observation films 101 are installed on both sides of the cassette body 1. The observation films 101 on the outer side of the cassette body 1 allow observation of the double-layer frame support plate and the pipette tip 3 of the corresponding protective sleeve assembly. The limiting soft sleeve 404 provides precise positioning and protection for the pipette tip 3; the soft material prevents scratching the tip, ensures the tip is placed vertically, and prevents it from tipping over or rolling. The perforated design facilitates air circulation, keeps the pipette tips dry, and reduces bacterial growth. It also works in conjunction with the observation plates 101 on both sides of the box body 1, allowing users to clearly observe the placement of the pipette tips within the limiting sleeve 404 from the outside, such as whether they are securely fixed and whether any are missing. This makes it convenient to count the number of pipette tips and check their condition at any time, improving the convenience and accuracy of experimental operations.

[0034] like Figure 1 , Figure 2 as well as Figure 3 As shown, in one embodiment, the locking assembly includes a first connecting plate 201 connected to the outside of the top cover plate 2, and a second connecting plate 203 installed on the upper side of the outer side of the arrangement box body 1. The first connecting plate 201 has an L-shaped structure and the connecting hole 202 corresponds vertically to the inner side of the first connecting plate 201. The first connecting plate 201 has a connecting hole 202, and the second connecting plate 203 is equipped with a protrusion 204 that engages with the inside of the connecting hole 202. After the mounting plate 4 is placed on the corresponding double-layer frame support plate, the double-layer frame support plate is installed inside the arrangement box body 1 for fixation. Then, the top opening of the arrangement box body 1 is sealed with the top cover plate 2. At this time, the connecting plate 1 201 on the top cover plate 2 is connected vertically with the connecting plate 203 on the outside of the arrangement box body 1. The connecting plate 1 201 and the connecting plate 203 are fixed by the buckle 204 inside the connecting hole 202. The locking assembly is provided with at least four sets to enhance the fixing and sealing effect between the arrangement box body 1 and the top cover plate 2. Even if the arrangement box body 1 falls to the ground, the top cover plate 2 will not be easily opened. The strong buckling fixing force can also ensure that the top cover plate 2 will not be easily opened, effectively preventing the pipette tip 3 from scattering, being lost or contaminated, ensuring the integrity and cleanliness of the tip, reducing the risk of experimental consumables loss, and providing all-round protection for the pipette tip 3.

[0035] The specific working method is as follows: First, prepare to store the pipette tip 3. Insert the double-layer frame support plate into the bottom surface of the arrangement box body 1 through the top opening. At this time, the positioning hole 403 on the support bottom ring 401 of the double-layer frame support plate is precisely matched and engaged with the docking post 102 on the bottom surface of the arrangement box body 1, so that the double-layer frame support plate is stably placed, laying the foundation for the subsequent placement of the pipette tip.

[0036] Next, insert the bottom of the pipette tip 3 into the top opening of the limiting sleeve 404 connected to the bottom of the mounting plate 4 in the double-layer frame support plate. The upper end of the limiting sleeve 404 extends to the upper surface of the mounting plate 4. Its soft material can protect the pipette tip, and the hollow holes on the outside facilitate air circulation. At least three rows of plastic partitions 5 on the top of the mounting plate 4 isolate the multiple sets of protective sleeve assemblies arranged horizontally, so that the pipette tips are arranged neatly and orderly.

[0037] After all the gun heads are placed, the top cover plate 2 is placed over the top opening of the arrangement box body 1, so that the L-shaped connecting plate 201 on the outside of the top cover plate 2 is aligned with the connecting plate 203 on the upper outside of the arrangement box body 1. The protrusion 204 on the connecting plate 203 is snapped into the connecting hole 202 of the connecting plate 201. At least four sets of locking components tightly fix the top cover plate 2 and the arrangement box body 1, ensuring the box is sealed and preventing the gun heads from falling, being damaged or contaminated, thus completing the gun head storage process and facilitating subsequent retrieval.

[0038] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
