[0023] In the pharmaceutical industry, long-distance transportation of medicines is frequently required. To ensure that medicines maintain their original medicinal properties during transportation, strict temperature control is necessary. Therefore, temperature-controlled boxes are an essential tool in the cold chain logistics market for pharmaceutical transportation.

[0024] Currently, temperature control boxes are mainly divided into VIP (vacuum insulation panel) temperature control boxes and PU (polyurethane) temperature control boxes. VIP temperature control boxes have better heat preservation performance but weaker protection performance; PU temperature control boxes have slightly better protection performance but weaker heat preservation performance. Therefore, it is necessary to develop a temperature control box with a more balanced heat preservation and protection performance.

[0025] To address the aforementioned problems, this application proposes a temperature-controlled box, such as... Figure 1 As shown, the temperature control box includes a protective housing 100 and an insulated housing 200. The protective housing 100 is made of foamed material, which has good impact resistance and cushioning performance, and is used to effectively absorb and disperse external impacts. Figure 2 and Figure 3 As shown, the protective enclosure 100 includes a first enclosure 110 and a first enclosure cover 120. The first enclosure cover 120 and the first enclosure 110 define a sealed first receiving cavity. The protective enclosure 100 also includes a first fastener 130. The first fastener 130 can be a soft component such as a strap, rope, or metal wire, which can play a role in binding and fixing.

[0026] The first fastener 130 has a first state and a second state, such as Figure 2 As shown, in the first state, the first fixing member 130 is arranged around the first housing 110 and the first housing cover 120 to restrict the relative movement of the first housing cover 120 and the first housing 110, thereby keeping the first accommodating cavity in a sealed state, such as... Figure 3 As shown, in the second state, the first fastener 130 can be unwound, thereby allowing the first cover 120 to open or separate relative to the first housing 110. By providing the first fastener 130 with two states, not only is the sealing performance of the protective housing 100 improved, enabling the protective housing 100 to have better thermal insulation performance, but the ease of operation is also improved, allowing the protective housing 100 to be opened and closed more quickly.

[0027] like Figure 4 As shown, the insulated box 200 of this application mainly serves the function of heat preservation. It is formed by splicing together insulation boards 210. The insulation boards 210 can be materials with good heat preservation performance, such as vacuum insulation boards. The insulated box 200 is located in the first accommodating cavity, and the interior of the insulated box 200 defines a second accommodating cavity. The second accommodating cavity is used to accommodate items to be shipped, such as medicines, vaccines, or other biological products that require constant temperature preservation.

[0028] In some embodiments, such as Figure 7 As shown, the insulated box 200 includes a third box 201, a first bottom cover 203, and a third box cover 202. The third box 201 has a hollow structure with open ends. The first bottom cover 203 and the third box cover 202 are respectively installed on both ends of the third box 201 to form a third accommodating cavity for accommodating items to be shipped. Based on the above, the insulated box 200 is formed by splicing insulated panels 210, wherein the insulated panels 210 include a first insulated panel 211 and a second insulated panel 214. Multiple first insulated panels 211 are spliced ​​to form the third box 201, and the second insulated panel 214 serves as the first bottom cover 203 and / or the third box cover 202, connected to both ends of the third box 201.

[0029] Furthermore, such as Figure 7 As shown, the first bottom cover 203 and the third box cover 202, along with the projection area along the vertical direction, can completely cover each of the first insulation panels 211 of the third box 201.

[0030] Furthermore, if the first insulation board 211 is a VIP insulation board, the insulation effect will be greatly reduced because VIP material is prone to breakage upon impact. Based on the aforementioned, while some surfaces of the insulated box 200 are covered and protected by packing straps, cross-fiber tape, etc., some exposed surfaces are still susceptible to breakage due to impact. Therefore, the exposed parts of the insulated box 200 need to be protected. For example, the top surface of the third box 201, the inner wall surface of the third box 201, and the inner wall surface of the third box cover 202 can be protected with PET material or other materials to improve the stability of the insulation effect of the insulated box 200.

[0031] Furthermore, the individual first insulation boards 211 abut against each other. For example... Figure 7 As shown, each of the first insulation panels 211 constituting the third housing 201 includes a first inner side surface 212 facing the third accommodating cavity, and a first end surface 213 adjacent to the first inner side surface 212, such as... Figure 7 As shown, the first end face 213 refers to the end face of the first insulation board 211 along the circumferential direction of the third housing 201. Two adjacent first insulation boards 211 are arranged vertically, with the first end face 213 of one first insulation board 211 abutting against the first inner side surface 212 of the other first insulation board 211. This arrangement ensures that each first insulation board 211 abuts against the first inner side surface 212 of the preceding first insulation board 211, and its first inner side surface 212 is abutted against by the first end face 213 of the following first insulation board 211, thereby forming a stable structure that supports each other.

[0032] Understandably, the temperature-controlled box in this application adopts a double-layer structure design, which not only improves the overall insulation effect but also enhances its resistance to pressure and impact. The protective box body 100, as the outer protective layer, effectively resists the physical impact of the external environment on the box body during transportation; while the insulated box body 200 ensures the stability of the internal temperature, preventing temperature fluctuations from affecting the quality of the items to be shipped. In practical applications, this temperature-controlled box can flexibly adapt to the insulation requirements of different medicines according to transportation needs, providing a safer and more reliable solution for pharmaceutical cold chain logistics.

[0033] Based on the foregoing, the protective enclosure 100 is made of foamed material, such as EPP (high-density polypropylene) or EPE (polyethylene foam). EPP material has excellent cushioning and insulation properties, making it suitable for manufacturing small temperature control boxes. It can maintain structural integrity when subjected to compression or impact, effectively protecting the internal insulation enclosure 200 from damage. EPE material has slightly lower cushioning and insulation properties, but it is less expensive and easier to process and mold, making it more suitable for manufacturing large temperature control boxes. In this embodiment, the volume of the temperature control box is approximately 3L to 60L, therefore, EPP material is preferred as the material for the protective enclosure 100. The insulation board 210 is preferably made of VIP (vacuum insulation board). VIP board has extremely low thermal conductivity, which can significantly improve the insulation performance of the insulation enclosure 200. Furthermore, VIP board is thinner and lighter, effectively reducing the volume occupied by the insulation enclosure 200 and improving space utilization under the same insulation requirements.

[0034] In some embodiments, such as Figure 3 As shown, the first box 110 includes a bottom wall and four side walls, and its top is a first opening 111. The protective box 100 is provided with a first positioning groove 101 surrounding the first box 110 and the first box cover 120. More specifically, the two opposite side walls of the first box 110 form a partial groove segment extending in the vertical direction. A partial groove segment is provided on the bottom wall of the first box 110. The groove segment on the bottom wall is connected to the groove segment on the side wall. The top surface of the first box cover 120 is also provided with a groove segment. When the first box cover 120 is closed on the first box 110, the groove segment on the first box cover 120 together with the groove segments on the side wall and the bottom wall to form the first positioning groove 101.

[0035] The first fixing member 130 is located in the first positioning groove 101. It should be noted that the first positioning groove 101 serves to position and limit the first fixing member 130, ensuring its stability during installation and use and preventing displacement. Additionally, the first positioning groove 101 also accommodates the first fixing member 130, preventing it from protruding from the surface of the protective housing 100 and affecting the overall structural flatness, thus avoiding unnecessary space occupation. The depth of the first positioning groove 101 can be greater than the thickness of the first fixing member 130, completely accommodating it and embedding it within the groove without exposure. Alternatively, the depth of the first positioning groove 101 can be less than the thickness of the first fixing member 130, preventing an excessively deep groove from affecting the structural strength of the protective housing 100. Therefore, the depth of the first positioning groove 101 needs to be determined by considering various factors such as the thickness of the first fixing member 130 and the structural strength of the materials.

[0036] Furthermore, the protective enclosure 100 also includes a second fastener 140, which is arranged around the side wall of the first enclosure 110, such as... Figure 2 and Figure 3 As shown, the second fastener 140 is wrapped around the four side walls of the first housing 110, thus encircling the entire perimeter of the first housing 110, further enhancing the overall structural stability of the protective housing 100. Furthermore, the first fastener 130 and the second fastener 140 are connected, and the second fastener 140 can prevent the first fastener 130 from falling off. For example, as... Figure 3 As shown, at the overlap of the first fixing member 130 and the second fixing member 140, the first fixing member 130 is pressed against the second fixing member 140 below it, thereby further preventing the first fixing member 130 from shifting during use. Additionally, as... Figure 2 As shown, the first fixing member 130 can be a strap, with the buckle of the strap located at the top of the protective housing 100. When the first fixing member 130 is in the first state, the strap is tightened to the outside of the first housing 110, securing it firmly to the protective housing 100 and preventing loosening or detachment due to external vibration or collision. Figure 3 As shown, when the first fastener 130 is in the second state, the strap is loosened, thereby separating the two ends of the strap to facilitate the removal or placement of the first housing 110 from or into the protective housing 100. At this time, the second fastener 140 can limit the first fastener 130, preventing the strap from hanging down or getting tangled in the second state and avoiding the loss of the strap in the second state.

[0037] It is understood that in other embodiments, the first fastener 130 and the second fastener 140 may also be connected by Velcro, snap fasteners, or other means, and are not limited to this. Figure 3The shown connection.

[0038] In some embodiments, the top surface of the first housing 110 is an open opening, which is referred to as the first opening 111 for ease of description. A first cover 120 is placed over the first opening 111 to close it. It is understood that because the top surface of the first housing 110 is open, in actual use, the structural strength of the top of the first housing 110 is lower than that of the bottom. When the first housing 110 is subjected to external pressure or impact, the top of the first housing 110 is prone to deformation or damage. To improve the structural strength at the first opening 111, at least one reinforcing member 150 is provided around the side wall of the first housing 110, and this reinforcing member 150 is positioned close to the first opening 111. Figure 3 In the illustrated embodiment, the reinforcing member 150 is a ring structure, surrounding the upper part of the side wall of the first housing 110, adjacent to the first opening 111, to improve the structural rigidity and compressive strength around the first opening 111. The reinforcing member 150 can be a plastic strip, metal strip, rope, or other strip or bar material with sufficient strength, and its material can be selected according to actual needs.

[0039] In some embodiments, such as Figure 3 As shown, the outer wall of the side wall of the first housing 110 also defines a mounting groove 112 for housing a thermometer (not shown). The thermometer is used to measure the temperature inside the second accommodating cavity to ensure that the internal environment of the housing meets the temperature control requirements for stored items. The top of the mounting groove 112 extends to the top surface of the first housing 110, forming a second opening 113 on the top surface of the first housing 110 for inserting the thermometer. It is understood that the top surface of the first housing 110 or the inner wall of the first housing 110 may also be provided with a wire groove connecting the mounting groove 112 and the first accommodating cavity. This wire groove is used to pass through the thermometer's wires, so that the sensing end of the thermometer can extend into the second accommodating cavity to accurately measure the internal temperature. Simultaneously, the thermometer's device end is located in the mounting groove 112, with its display facing outwards for easy observation of the temperature value by the user.

[0040] Furthermore, when the first cover 120 is placed on the first housing 110, the second opening 113 is also closed by the first cover 120. The device end of the thermometer can be fixed in the mounting groove 112 by means of screws, clips, adhesive, etc.; or, the mounting groove 112 can be structurally designed to limit and fix the device end of the thermometer, for example (not shown in the figure), the mounting groove 112 extends into limiting protrusions on both sides along the width direction, so that the thermometer can be inserted into the mounting groove 112 from top to bottom, but the thermometer cannot be removed from the mounting groove 112 along the thickness direction of the side wall. When the first cover 120 is placed on the first housing 110, the second opening 113 is closed by the first cover 120, so the displacement of the thermometer in the vertical direction is also restricted. Thus, the thermometer fixed in the mounting groove 112 will not fall off or shift due to external force, ensuring the stability and reliability of its measurement.

[0041] In some embodiments, such as Figure 3 As shown, a positioning flange 121 is provided around the inner side of the first lid 120 along its circumference, and a positioning groove 115 is provided around the inner side of the top surface of the first box body 110 along its circumference. The first lid 120 and the first box body 110 are engaged through the positioning flange 121 and the positioning groove 115, thereby improving the alignment accuracy and connection stability between the lid and the box body. The engagement of the positioning flange 121 and the positioning groove 115 can also effectively prevent the lid from loosening or falling off during transportation or use. In addition, the engagement of the flange and the groove increases the path for cold air leakage, thereby reducing the loss of cold air inside the box body and improving the insulation performance of the box body.

[0042] Furthermore, the first cover 120 of the protective box 100 is connected to the cover of the insulated box 200 as an integral structure, thereby enabling the protective box 100 and the insulated box 200 to open and close synchronously, improving operational convenience.

[0043] In some embodiments, such as Figure 1 and Figure 5 As shown, the temperature control box also includes a cold storage chamber 300. The cold storage chamber 300 can be a single, integrally formed chamber with a cavity, allowing coolant to be injected into the cavity or filled with cold storage liquid or cold storage material to maintain a constant temperature environment inside the chamber during transportation. Alternatively, the cold storage chamber 300 can be composed of multiple ice blocks 310 assembled together, with each ice block 310 fixed to the insulated chamber 200 via slots or limiting structures, such as... Figure 5As shown, the cold storage box 300 is formed by splicing six ice blocks 310 together. Each ice block 310 has a trapezoidal structure, including an inner side 312, an outer side 311, and four connecting surfaces 313 located between the inner side 312 and the outer side 311. Each connecting surface 313 is inclined relative to the inner side 312 and the outer side 311, and the distance between two opposite connecting surfaces 313 gradually decreases along the direction from the outer side 311 to the inner side 312. In the illustrated embodiment, the cold storage box 300 is a cubic structure formed by splicing six ice blocks 310. Adjacent ice blocks 310 are arranged perpendicular to each other and abut against each other through the connecting surfaces 313. The outer side 311 of the ice block 310 can fit against the inner wall of the insulation box 200. Outward displacement is restricted by the insulation box 200, and inward displacement is restricted by the abutment of the connecting surfaces 313, thereby ensuring the structural stability of the entire cold storage box 300. This overlapping structure makes it extremely convenient to replace the ice pack 310. When it is necessary to adjust the temperature inside the chamber, or to extend or shorten the insulation time, the ice pack 310 can be replaced or added or removed as needed.

[0044] In some embodiments, since the temperature control box needs to be in contact with the ground for a long time, in order to prevent the bottom of the protective box 100 from being worn due to long-term friction, an outer casing 400 is often added to the outside of the protective box 100. The outer casing 400 is usually a protective shell made of cloth or hard material to enhance the overall durability and service life. Figure 6 As shown, the outer packaging box 400 includes a second box body 410 and a second box cover 420. The second box body 410 and the second box cover 420 are detachably connected to facilitate the replacement of the second box cover 420. For example, in some usage scenarios, the logistics label often needs to be attached to the outermost top surface of the entire temperature-controlled box, that is, to the second box cover 420 of the outer packaging box 400, for identification and transportation management. However, since the temperature-controlled box of this application is reusable, adhesive residue is easily left on the second box cover 420 of the outer packaging box 400 after the label is replaced, affecting the appearance and secondary use. To solve this problem, the second box cover 420 of the outer packaging box 400 is designed as a replaceable structure, which is detachably connected to the second box body 410 by means of buckles, magnets, zippers or Velcro, so as to facilitate the replacement of the second box cover 420 to maintain a clean appearance, while not affecting the reusability of the temperature-controlled box.

[0045] In addition, in conjunction with the foregoing, corresponding to the area on the protective enclosure 100 where the temperature groove is provided, the second enclosure 410 of the outer enclosure 400 is provided with a transparent observation window 430 so that the user can view the displayed value of the thermometer through the observation window 430.

[0046] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
