Description

Technical Field

[0001] This application relates to the field of biomedicine, and in particular to a freeze-thaw protection box. Background Technology

[0002] In large-scale industrial production processes in the biopharmaceutical field, a large number of storage bags are required for cell culture. During use, these storage bags need to be frozen, thawed, stored, and transported within freeze-thaw apparatus. Since the cells and other products within these storage bags are of high value, the storage bags stored in the freeze-thaw apparatus must be properly handled during freezing, storage, and transportation.

[0003] Existing technology typically involves storing the liquid storage bag in a freeze-thaw protection box, placing the freeze-thaw protection box inside the freeze-thaw apparatus, and stacking multiple freeze-thaw protection boxes on top of each other. However, this arrangement puts enormous pressure on the bottom freeze-thaw protection box, which can lead to its breakage. Utility Model Content

[0004] In view of this, the purpose of this application is to propose a freeze-thaw protection box, in which multiple freeze-thaw protection boxes can be stacked and placed inside a freeze-thaw instrument, thereby saving space inside the freeze-thaw instrument.

[0005] To achieve the above objectives, this application provides a freeze-thaw protection box, comprising:

[0006] A box body, the box body including a bottom wall and side walls disposed around the bottom wall;

[0007] A lid is located above and abuts against the side wall, and the lid, the side wall, and the bottom wall form a receiving cavity for storing a liquid storage bag.

[0008] The sidewall includes a first sidewall and a second sidewall disposed opposite to each other. The inner walls of the first sidewall and the second sidewall are respectively provided with a first protrusion and a second protrusion extending toward the receiving cavity. The lid abuts against the upper part of the first protrusion and the upper part of the second protrusion, respectively. When the liquid storage bag is located in the receiving cavity, the height of the liquid storage bag in the vertical direction is lower than the height of the position where the first protrusion abuts against the lid and the height of the position where the second protrusion abuts against the lid.

[0009] Furthermore, the first protrusion and the second protrusion are arranged opposite to each other, and the first protrusion and the second protrusion divide the receiving cavity into a first cavity and a second cavity that are interconnected. The first cavity is used to store the liquid storage bag, and the second cavity is used to store the infusion tube.

[0010] Furthermore, the volume of the first cavity is larger than the volume of the second cavity.

[0011] Furthermore, the first protrusion includes a first end and a second end opposite to each other, the first end being connected to the first sidewall, and the height of the second end being less than the height of the first end in the vertical direction.

[0012] Furthermore, a plurality of reinforcing ribs are provided between the first end and the second end, and the plurality of reinforcing ribs are evenly distributed on the two inner sidewalls of the first protrusion located between the first end and the second end.

[0013] Furthermore, a first recess is formed between the outer wall of the first protrusion and the outer wall of the first sidewall;

[0014] And / or, a second recess is formed between the outer wall of the second protrusion and the outer wall of the second sidewall.

[0015] Furthermore, the box body includes an edge portion, which is disposed above the side wall and extends horizontally in a direction away from the receiving cavity; the edge portion is provided with a groove; the box cover is provided with a protrusion, which cooperates with the groove and protrudes towards the receiving cavity.

[0016] Furthermore, the edge portion is provided with a first grip portion and a second grip portion, which are respectively located on two opposite sides of the edge portion.

[0017] Furthermore, the inner wall of the box is provided with multiple slots.

[0018] Furthermore, the slots are evenly distributed on at least one of the sidewalls;

[0019] And / or, the slots are evenly distributed on the bottom wall.

[0020] Compared with the prior art, the freeze-thaw protection box provided in this application has a box body and a box cover. The box cover abuts against the upper part of the first protrusion and the upper part of the second protrusion, respectively. The first protrusion and the second protrusion can provide support for the box cover, so that multiple freeze-thaw protection boxes can be stacked on top of each other to save space. When the liquid storage bag is located in the receiving cavity, the liquid storage bag is lower than the first protrusion and the second protrusion in the vertical direction, thereby preventing the box cover from contacting the liquid storage bag and protecting the liquid storage bag.

[0029] Please refer to Figures 1 to 5The illustration shows an embodiment of a freeze-thaw protection box 100 provided in this application, comprising: a box body 10 and a box lid 20. The box body 10 includes a bottom wall 11 and a side wall 12 disposed around the bottom wall 11. The box lid 20 is located above and abuts against the side wall 12, and the box lid 20, the side wall 12, and the bottom wall 11 form a receiving cavity 30 for storing a liquid storage bag (not shown in the figure).

[0030] The sidewall 12 includes a first sidewall 121 and a second sidewall 122 disposed opposite to each other. The inner walls of the first sidewall 121 and the second sidewall 122 are respectively provided with a first protrusion 123 and a second protrusion 124 extending toward the receiving cavity 30. The lid 20 abuts against the upper part of the first protrusion 123 and the upper part of the second protrusion 124 respectively.

[0031] When the liquid storage bag is located in the receiving cavity 30, the height of the liquid storage bag in the vertical direction is lower than the height of the first protrusion 123 abutting against the lid 20 and the height of the second protrusion 124 abutting against the lid 20.

[0032] The freeze-thaw protection box 100 provided in this application has a box body 10 and a box cover 20. The box cover 20 abuts against the upper part of the first protrusion 123 and the upper part of the second protrusion 124, respectively. The first protrusion 123 and the second protrusion 124 can provide support for the box cover 20, thereby allowing multiple freeze-thaw protection boxes 100 to be stacked on top of each other, saving space, increasing the support area of ​​the box cover 20, and thus improving the load-bearing capacity of the box cover 20. When the liquid storage bag is located in the receiving cavity 30, the liquid storage bag is lower than the first protrusion 123 and the second protrusion 124 in the vertical direction, thereby preventing the box cover 20 from contacting the liquid storage bag and protecting the liquid storage bag.

[0033] Optionally, the first protrusion 123 and the second protrusion 124 are arranged opposite to each other, and the first protrusion 123 and the second protrusion 124 divide the receiving cavity 30 into a first cavity 31 and a second cavity 32 that are interconnected. The first cavity 31 is used to store the liquid storage bag, and the second cavity 32 is used to store the infusion tube.

[0034] The freeze-thaw protection box 100 provided in this application divides the receiving cavity 30 into a first cavity 31 and a second cavity 32 that are interconnected by providing a first protrusion 123 and a second protrusion 124. The first cavity 31 and the second cavity 32 respectively accommodate the liquid storage bag and the infusion tube. When placed, the infusion tube passes through the gap between the first protrusion 123 and the second protrusion 124 into the second cavity 32. The first protrusion 123 and the second protrusion 124 can provide a limit for the infusion tube, so as to keep the infusion tube stable during transportation.

[0035] Optionally, the first protrusion 123 and the second protrusion 124 can be staggered. The projections of the first protrusion 123 and the second protrusion 124 onto the side wall 12 where the first side wall 121 and the second side wall 122 intersect can overlap or not overlap. This application does not impose any restrictions on this.

[0036] Optionally, in one embodiment of the freeze-thaw protection box 100 provided in this application, the volume of the first cavity 31 is larger than the volume of the second cavity 32.

[0037] Since the volume of the storage bag is larger than that of the infusion tube, the volume of the first cavity 31 is set to be larger than that of the second cavity 32, so that the first cavity 31 and the second cavity 32 are respectively adapted to the storage bag and the infusion tube, thereby reducing the volume occupied by the freeze-thaw protection box 100 while increasing the storage volume of the freeze-thaw protection box 100.

[0038] Optionally, in one embodiment, the first protrusion 123 includes a first end portion 1231 and a second end portion 1232 opposite to each other. The first end portion 1231 is connected to the first sidewall 121, and the height of the second end portion 1232 in the vertical direction is less than the height of the first end portion 1231, such that the upper part of the first protrusion 123 is an inclined surface extending toward the first protrusion 123, and the cover 20 abuts against the highest point of the inclined surface of the upper part of the first protrusion 123.

[0039] Similarly, the upper part of the second protrusion 124 can also be set as an inclined surface, just like the first protrusion 123. This application will not elaborate further here.

[0040] The freeze-thaw protection box 100 provided in this application reduces the volume occupied by the first protrusion 123 and the second protrusion 124 by setting the upper part of the first protrusion 123 and the upper part of the second protrusion 124 as inclined surfaces, thereby increasing the storage volume of the receiving cavity 30 and accommodating a larger liquid storage bag.

[0041] Optionally, in one embodiment, the upper part of the first protrusion 123 may be set as an inclined surface, while the upper part of the second protrusion 124 may not be set as an inclined surface.

[0042] In another embodiment, the upper part of the second protrusion 124 may be set as an inclined surface, while the upper part of the first protrusion 123 may not be set as an inclined surface. This application does not impose any restrictions on this.

[0043] Optionally, a plurality of reinforcing ribs 125 are provided between the first end 1231 and the second end 1232, and the plurality of reinforcing ribs 125 are evenly distributed on the two inner sidewalls of the first protrusion 123 located between the first end 1231 and the second end 1232.

[0044] Similarly, the second protrusion 124 may also be provided with multiple reinforcing ribs 125, which will not be described in detail in this application.

[0045] The freeze-thaw protection box 100 provided in this application improves the structural strength of the first protrusion 123 and the second protrusion 124 by providing multiple reinforcing ribs 125 on both the first protrusion 123 and the second protrusion 124, thereby enabling the first protrusion 123 and the second protrusion 124 to bear greater weight.

[0046] Optionally, there are three reinforcing ribs 125 on the first protrusion 123 and three reinforcing ribs 125 on the second protrusion 124, and the reinforcing ribs 125 on the first protrusion 123 and the second protrusion 124 are evenly arranged in the direction toward the receiving cavity 30.

[0047] Optionally, two reinforcing ribs 125 may be provided on the first protrusion 123, and four reinforcing ribs 125 may be provided on the second protrusion 124.

[0048] Optionally, four reinforcing ribs 125 are provided on the first protrusion 123 and two reinforcing ribs 125 are provided on the second protrusion 124. This application does not limit the number of reinforcing ribs 125.

[0049] Optionally, in one embodiment of the freeze-thaw protection box 100 provided in this application, a first recess 126 is formed between the outer wall of the first protrusion 123 and the outer wall of the first side wall 121. A second recess 127 is formed between the outer wall of the second protrusion 124 and the outer wall of the second side wall 122.

[0050] The freeze-thaw protection box 100 provided in this application reduces the amount of material used in manufacturing the freeze-thaw protection box 100 by providing a first recess 126 and a second recess 127, thereby saving costs.

[0051] The box body 10 includes an edge portion 13 disposed on the upper part of the side wall 12 and extending in a direction away from the receiving cavity 30. The edge portion 13 is provided with a groove 131, and the box cover 20 is provided with a protruding protrusion 21 that mates with the groove 131 and faces the receiving cavity 30. The protrusion 21 is located in the groove 131 to couple and embed the box cover 20 and the box body 10 into each other.

[0052] The freeze-thaw protection box 100 provided in this application has a groove 131 on the edge 13 and a protrusion 21 on the cover 20 to couple and embed the cover 20 and the box body 10 together, thereby ensuring the overall sealing of the freeze-thaw protection box 100.

[0053] Optionally, in one embodiment, the area enclosed by the protrusion 21 on the cover 20 is smaller than the area of ​​the bottom wall 11, and a corresponding recess 22 is provided in the direction away from the receiving cavity 30 on the protrusion 21, so that when two freeze-thaw protection boxes 100 are stacked, part of the bottom wall 11 of the upper freeze-thaw protection box 100 will cooperate with the recess 22 of the lower freeze-thaw protection box 100 to limit and fix the upper freeze-thaw protection box 100, thereby keeping the upper freeze-thaw protection box 100 stable during transportation and improving the overall structural strength of the freeze-thaw protection box 100 after stacking.

[0054] Optionally, the edge portion 13 is provided with a first grip portion 132 and a second grip portion 133, which are respectively located on two opposite sides of the edge portion 13.

[0055] The freeze-thaw protection box 100 provided in this application has a first grip 132 and a second grip 133 on the edge 13, which makes it convenient for the user to operate the freeze-thaw protection box 100 with both hands. At the same time, the presence of the first grip 132 and the second grip 133 also makes it convenient for the user to open the box lid 20.

[0056] Optionally, the first grip portion 132 and the second grip portion 133 are strip-shaped grooves, which not only facilitate gripping, but also make it easy for the user to separate the lid 20 from the box body 10 after the lid 20 is coupled and inserted into the box body 10.

[0057] Optionally, the lid 20 and body 10 of the freeze-thaw protection box 100 are made of polystyrene material. Polystyrene material can withstand low temperatures of -80°C and has high corrosion resistance, making it a suitable material for manufacturing the freeze-thaw protection box 100.

[0058] Optionally, the inner wall of the box body 10 is provided with multiple slots (not shown). The multiple slots can be evenly distributed on the side walls and / or inner walls of the box body 10, thereby increasing the heat dissipation area of ​​the box body 10 and thus improving the freezing effect of the freeze-thaw protection box 100 provided in this application.
