Description

Technical Field

[0001] This utility model relates to the field of freeze-thaw protection technology, and in particular to a protective tray for low-temperature liquid storage bags. Background Technology

[0002] In the fields of biopharmaceuticals and pharmaceutical research and development, it is often necessary to cryopreserve and subsequently thaw liquids containing bioactive components, such as cell culture media, biological agents, and experimental sample solutions. Currently, storage bags are commonly used as flexible storage containers. However, their material becomes more brittle in ultra-low temperature environments, and they are prone to breakage due to external impacts and compression during handling and freeze-thaw cycles. This can lead to subsequent liquid leakage, affecting the inactivation of bioactive components or causing environmental pollution, resulting in significant losses to experiments and production. Traditional trays lack positioning treatment for storage bags, which can easily cause deformation and breakage of the storage bags at low temperatures, affecting the cryopreservation process. Therefore, there is an urgent need for a cryogenic storage bag protective tray to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a protective tray for low-temperature liquid storage bags, which solves the problem of protecting liquid storage bags during the thawing process in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution: A cryogenic liquid storage bag protective tray, comprising: The upper and lower shell trays are provided with limiting edges along their circumference. A liquid storage bag groove is provided on the long side of the limiting edges. Multiple sets of upper shell limiting protrusions are provided in the upper shell tray near the liquid storage bag groove, and multiple sets of lower shell limiting protrusions are provided in the lower shell tray near the liquid storage bag groove. When the upper shell tray covers the lower shell tray, the upper shell limiting protrusions and the lower shell limiting protrusions fit together to position the upper and lower shell trays. The liquid bag section is located at the bottom of the upper shell tray and the lower shell tray, and the liquid bag section protrudes to the side away from the bottom of the upper shell tray and the lower shell tray, and a liquid guiding protrusion is provided at the center of the liquid bag section; Two sets of handles are symmetrically arranged along the wide edges of the upper and lower shell trays for manual handling of the trays.

[0005] To achieve the above technical solution, when the liquid storage bag needs to be frozen and thawed, the liquid storage bag is placed in the lower shell tray, and then the upper shell tray covers the lower shell tray. This provides sufficient freezing and thaw space for the liquid storage bag using the upper and lower shell trays, while also protecting the liquid storage bag and preventing external factors from damaging it and affecting its normal use.

[0006] The limiting edge surrounds the liquid storage bag within the lower shell tray, and the side groove of the liquid storage bag facilitates the placement of the interface on the liquid storage bag, avoiding interference with the internal storage space. The upper and lower shell limiting protrusions fit together, positioning the upper and lower shell trays when they overlap, preventing misalignment and interference with the liquid storage bag. The liquid bag protrudes towards the bottom, away from the upper and lower shell trays, resulting in a more even distribution of liquid within the bag and preventing excessive concentration in one area. Combined with the liquid guiding protrusion, this further enhances the uniformity of liquid distribution and ensures the stability of the freeze-thaw effect.

[0007] In one embodiment of the present invention, the upper shell limiting protrusion and the lower shell limiting protrusion are each composed of two sets of X-direction limiting protrusions and one set of Z-direction limiting protrusions. The two sets of X-direction limiting protrusions are symmetrically arranged on both sides of the Z-direction limiting protrusion. Both the X-direction limiting protrusions and the Z-direction limiting protrusions are L-shaped protrusions.

[0008] To achieve the above technical solution, in order to ensure the stability of the upper shell tray covering the lower shell tray, two sets of X-direction limiting protrusions are symmetrically arranged on both sides of the Z-direction limiting protrusion, which respectively play a positioning role in the X and Z directions. This allows the upper shell tray to stably cover the lower shell tray, ensuring the stability of the liquid storage space between the upper and lower shell trays and solving the positioning problem of traditional trays.

[0009] In one embodiment of this utility model, the long side of the X-direction limiting protrusion is arranged parallel to the length direction of the limiting perimeter, and the long side of the Z-direction limiting protrusion is arranged perpendicular to the length direction of the limiting perimeter. Furthermore, when the upper shell tray covers the lower shell tray, the short side of the upper shell limiting protrusion is located at the long side of the lower shell limiting protrusion, forming a limiting structure. The short side of the lower shell limiting protrusion is located at the long side of the upper shell limiting protrusion, thereby achieving the positioning of the upper shell tray and the lower shell tray.

[0010] To achieve the above technical solution, the short side of the upper shell limiting protrusion and the long side of the lower shell limiting protrusion are fitted together. In this way, when X-axis or Z-axis displacement occurs between the upper shell tray and the lower shell tray, the short side of the upper shell limiting protrusion and the long side of the lower shell limiting protrusion can be used to limit the displacement between the upper shell tray and the lower shell tray, thus ensuring the assembly stability between the upper shell tray and the lower shell tray.

[0011] In one embodiment of the present invention, an upper shell positioning hole is provided on the X-direction limiting protrusion of the upper shell tray. A set of upper shell positioning holes is provided on the long side and the short side of the X-direction limiting protrusion, respectively. A lower shell positioning hole is provided on the X-direction limiting protrusion of the lower shell tray. When the upper shell tray covers the lower shell tray, the position of the lower shell positioning hole matches the position of the upper shell positioning hole.

[0012] To achieve the above technical solution, a set of upper shell positioning holes and a set of lower shell positioning holes are respectively set on the long side and the short side of the limiting protrusion. When using bolts for locking, the locking stability of the upper shell positioning holes and the lower shell positioning holes can be improved, thereby distributing the bolt force more evenly during the assembly of the upper shell tray and the lower shell tray, and further improving the assembly stability of the upper shell tray and the lower shell tray.

[0013] In one embodiment of the present invention, two sets of positioning posts are symmetrically arranged on the wide side of one side of the upper shell tray and the lower shell tray. Each set of positioning posts is provided with a positioning through hole. When the upper shell tray covers the lower shell tray, the positioning posts of the upper shell tray and the lower shell tray are locked together by bolts passing through the positioning through holes.

[0014] To achieve the above technical solution, the height of the positioning post is matched with the maximum height of the limiting edge. This reduces the stress on the limiting edge when the upper shell tray covers the lower shell tray. By using bolts to lock the positioning post through the positioning through hole, the assembly stability of the upper shell tray and the lower shell tray can be guaranteed, and displacement deviation between the upper shell tray and the lower shell tray can be avoided.

[0015] In one embodiment of the present invention, a liquid bag limiting seat is provided between the two sets of positioning columns, and the length of the liquid bag limiting seat matches the length of the handle.

[0016] By implementing the above technical solution, the liquid bag limiting seat can prevent the liquid storage bag from going out of bounds and ensure the stability of the liquid storage bag between the upper and lower shell trays.

[0017] In one embodiment of this utility model, both the upper shell tray and the lower shell tray are made of HDPE material.

[0018] The above technical solution can maintain good impact resistance after freeze-thaw cycles, meet freeze-thaw requirements, and thus better protect the liquid storage bag from external interference.

[0019] As described above, the low-temperature resistant liquid storage bag protective tray of this utility model has the following beneficial effects: when the liquid storage bag needs to be frozen and thawed, the liquid storage bag is placed in the lower shell tray, and then the upper shell tray covers the lower shell tray. In this way, the upper shell tray and the lower shell tray provide sufficient freezing and thawing space for the liquid storage bag, while also protecting the liquid storage bag and preventing external factors from damaging the liquid storage bag and affecting its normal use.

[0020] The limiting edge surrounds the liquid storage bag within the lower shell tray, and the side groove of the liquid storage bag facilitates the placement of the interface on the liquid storage bag, avoiding interference with the internal storage space. The upper and lower shell limiting protrusions fit together, positioning the upper and lower shell trays when they overlap, preventing misalignment and interference with the liquid storage bag. The liquid bag protrudes towards the bottom, away from the upper and lower shell trays, resulting in a more even distribution of liquid within the bag and preventing excessive concentration in one area. Combined with the liquid guiding protrusion, this further enhances the uniformity of liquid distribution and ensures the stability of the freeze-thaw effect. Attached Figure Description

[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0026] Please see Figures 1 to 3It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0027] Please see Figures 1 to 3 This utility model provides a protective tray for a cryogenic liquid storage bag, including an upper shell tray 1 and a lower shell tray 2. A limiting edge 3 is provided along the circumference of the upper shell tray 1 and the lower shell tray 2. A liquid storage bag side groove 4 is provided on the long side of the limiting edge 3. Multiple sets of upper shell limiting protrusions are provided in the upper shell tray 1 near the liquid storage bag side groove 4. Multiple sets of lower shell limiting protrusions are provided in the lower shell tray 2 near the liquid storage bag side groove 4. When the upper shell tray 1 covers the lower shell tray 2, the upper shell limiting protrusions and the lower shell limiting protrusions fit together to position the upper shell tray 1 and the lower shell tray 2. When the liquid storage bag needs to be frozen and thawed, the liquid storage bag is placed in the lower shell tray 2, and then the upper shell tray 1 covers the lower shell tray 2. Thus, the upper shell tray 1 and the lower shell tray 2 provide sufficient freezing and thaw space for the liquid storage bag, while also protecting the liquid storage bag and preventing external factors from damaging the liquid storage bag and affecting its normal use.

[0028] The liquid bag section 5 is located at the bottom of the upper shell tray 1 and the lower shell tray 2. The liquid bag section 5 protrudes to the side away from the bottom of the upper shell tray 1 and the lower shell tray 2. A liquid guiding protrusion 14 is provided at the center of the liquid bag section 5. Two sets of handle sections 6 are symmetrically arranged along the wide edge of the upper shell tray 1 and the lower shell tray 2 for manual handling of the trays.

[0029] The limiting edge 3 can surround the liquid storage bag inside the lower shell tray 2, and the liquid storage bag side groove 4 can facilitate the placement of the interface on the liquid storage bag, avoiding interference with the internal storage space of the liquid storage bag. By using the upper shell limiting protrusion and the lower shell limiting protrusion to fit together, the upper shell tray 1 and the lower shell tray 2 can be positioned when the upper shell tray 1 covers the lower shell tray 2, avoiding the upper shell tray 1 and the lower shell tray 2 from intersecting and interfering with the liquid storage bag. The liquid bag part 5 protrudes to the side away from the bottom of the upper shell tray 1 and the lower shell tray 2, which can better and more evenly distribute the liquid in the liquid storage bag, and avoid excessive concentration of liquid in one place. Together with the liquid guiding protrusion 14, it can improve the uniformity of liquid distribution and ensure the stability of the freeze-thaw effect.

[0030] Both the upper shell limiting protrusion and the lower shell limiting protrusion are composed of two sets of X-direction limiting protrusions 7 and one set of Z-direction limiting protrusions 8. The two sets of X-direction limiting protrusions 7 are symmetrically arranged on both sides of the Z-direction limiting protrusions 8. Both the X-direction limiting protrusions 7 and the Z-direction limiting protrusions 8 are L-shaped protrusions. In order to ensure the stability of the upper shell tray 1 covering the lower shell tray 2, the two sets of X-direction limiting protrusions 7 are symmetrically arranged on both sides of the Z-direction limiting protrusions 8, which respectively play a positioning role in the X and Z directions. This allows the upper shell tray 1 to stably cover the lower shell tray 2, ensuring the stability of the liquid storage space between the upper shell tray 1 and the lower shell tray 2, and solving the positioning problem of traditional trays.

[0031] The long side of the X-direction limiting protrusion 7 is arranged parallel to the length direction of the limiting perimeter 3, and the long side of the Z-direction limiting protrusion 8 is arranged perpendicular to the length direction of the limiting perimeter 3. When the upper shell tray 1 covers the lower shell tray 2, the short side of the upper shell limiting protrusion is located at the long side of the lower shell limiting protrusion, forming a limiting structure. The short side of the lower shell limiting protrusion is located at the long side of the upper shell limiting protrusion, so as to achieve the positioning of the upper shell tray 1 and the lower shell tray 2.

[0032] By utilizing the short side of the upper shell limiting protrusion and the long side of the lower shell limiting protrusion to fit together, when X- or Z-direction displacement occurs between the upper shell tray 1 and the lower shell tray 2, the short side of the upper shell limiting protrusion and the long side of the lower shell limiting protrusion can act as a limit, preventing X- or Z-direction displacement between the upper shell tray 1 and the lower shell tray 2 and ensuring the assembly stability between the upper shell tray 1 and the lower shell tray 2.

[0033] An upper shell positioning hole 9 is provided on the X-direction limiting protrusion 7 of the upper shell tray 1. A set of upper shell positioning holes 9 is provided on the long side and the short side of the X-direction limiting protrusion 7 respectively. A lower shell positioning hole 10 is provided on the X-direction limiting protrusion 7 of the lower shell tray 2. When the upper shell tray 1 covers the lower shell tray 2, the position of the lower shell positioning hole 10 matches the position of the upper shell positioning hole 9.

[0034] The upper shell positioning hole 9 and the lower shell positioning hole 10 are respectively set on the long side and the short side of the limiting protrusion. When the bolts are used for locking, the locking stability of the upper shell positioning hole 9 and the lower shell positioning hole 10 can be improved, thereby distributing the bolt force more evenly when assembling the upper shell tray 1 and the lower shell tray 2, and further improving the assembly stability between the upper shell tray 1 and the lower shell tray 2.

[0035] Two sets of positioning posts 11 are symmetrically arranged on the wide side of one side of the upper shell tray 1 and the lower shell tray 2. Both sets of positioning posts 11 are provided with positioning through holes 12. When the upper shell tray 1 covers the lower shell tray 2, the positioning posts 11 of the upper shell tray 1 and the lower shell tray 2 are locked together by bolts passing through the positioning through holes 12.

[0036] The height of the positioning post 11 matches the maximum height of the limiting edge 3, which reduces the stress on the limiting edge 3 when the upper shell tray 1 covers the lower shell tray 2. By using bolts to lock the positioning post 11 through the positioning through hole 12, the assembly stability of the upper shell tray 1 and the lower shell tray 2 can be guaranteed, and displacement deviation between the upper shell tray 1 and the lower shell tray 2 can be avoided.

[0037] A liquid bag limiting seat 13 is provided between the two sets of positioning posts 11. The length of the liquid bag limiting seat 13 matches the length of the handle part 6. The liquid bag limiting seat 13 can prevent the liquid bag from going out of bounds and ensure the stability of the liquid bag between the upper shell tray 1 and the lower shell tray 2.

[0038] Both the upper shell tray 1 and the lower shell tray 2 are made of HDPE material, which can maintain good impact resistance after freeze-thaw cycles, meet freeze-thaw requirements, and thus better protect the liquid storage bag from external interference. Compared with metal trays, the HDPE upper shell tray 1 and lower shell tray 2 have better corrosion resistance, longer service life, lighter weight, wider application range, and are environmentally friendly materials that can be recycled.

[0039] When a liquid storage bag needs to be frozen and thawed, this invention places the storage bag inside the lower shell tray 2, and then the upper shell tray 1 covers the lower shell tray 2. This provides ample freezing and thawing space for the storage bag while also protecting it from external damage that could affect its normal use. The limiting edge 3 encloses the storage bag within the lower shell tray 2, and the storage bag side groove 4 facilitates the placement of the interfaces on the storage bag, preventing damage to the internal storage space. To prevent interference, the upper shell limiting protrusion and the lower shell limiting protrusion fit together, which can position the upper shell tray 1 and the lower shell tray 2 when the upper shell tray 1 covers the lower shell tray 2, avoiding the interference caused by the misalignment of the upper shell tray 1 and the lower shell tray 2. The liquid bag part 5 protrudes to the side away from the bottom of the upper shell tray 1 and the lower shell tray 2, which can better and more evenly distribute the liquid in the liquid bag and avoid excessive concentration of liquid in one place. In conjunction with the liquid guiding protrusion 14, it can improve the uniformity of liquid distribution and ensure the stability of the freeze-thaw effect.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
