Description

Technical Field

[0001] This utility model relates to the field of cold chain logistics technology, and in particular to a temperature-controlled box. Background Technology

[0002] 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.

[0003] In related technologies, temperature control boxes include a protective enclosure and an insulated enclosure within the protective enclosure, thus providing both good insulation and protection. When the temperature control box is small, the protective enclosure is made of EPP (high-density polypropylene). However, when the temperature control box is large, molding EPP into the enclosure is more difficult and costly; therefore, EPE (polyethylene foam) is generally used to make the protective enclosure. However, protective enclosures made of EPE have lower strength, making the temperature control box easily damaged by impact. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a temperature control box, which has a reinforced outer casing on the outside of the protective casing, thereby effectively improving the overall pressure resistance of the temperature control box.

The first accommodating cavity is adapted to the shape of the protective box body, allowing the protective box body to be tightly embedded in the reinforced box body, further enhancing the stability of the overall structure. To avoid occupying too much space, the reinforced box body is relatively thin. Therefore, the reinforced box body also includes a support frame, which can play a role in structural reinforcement of the reinforced box body. The support frame can locally increase the thickness of the reinforced box body, so that the reinforced box body has better load-bearing capacity and deformation resistance.

[0022] 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.

[0023] In related technologies, temperature control boxes include a protective enclosure and an insulated enclosure within the protective enclosure, thus providing both good insulation and protection. When the temperature control box is small, the protective enclosure is made of EPP (high-density polypropylene). However, when the temperature control box is large, molding EPP into the enclosure is more difficult and costly; therefore, EPE (polyethylene foam) is generally used to make the protective enclosure. However, protective enclosures made of EPE have lower strength, making the temperature control box easily damaged by impact.

[0024] To solve the above problems, such as Figure 1 As shown, this application proposes a temperature-controlled box, which includes a protective box body 200 and an insulated box body 300. The protective box body 200 is made of foamed material, which has good impact resistance and cushioning performance, and is used to effectively absorb and disperse external impacts. The insulated box body 300 mainly serves a heat preservation function and is formed by splicing together insulation boards. The insulation boards can be materials with good heat preservation performance, such as vacuum insulation boards, to ensure the temperature stability of the medicine during transportation. The insulated box body 300 is located in the second accommodating cavity of the protective box body 200, and the interior of the insulated box body 300 defines a third accommodating cavity for accommodating items to be shipped, such as medicines, vaccines, or other biological products that require constant temperature preservation.

[0025] 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 200, as the outer protective layer, can effectively resist the physical impact of the external environment on the box body during transportation; while the insulated box body 300 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.

[0026] The protective enclosure 200 is made of foamed material, such as EPP (high-density polypropylene) or EPE (polyethylene foam). EPP has excellent cushioning and insulation properties, making it suitable for manufacturing small temperature control boxes. It can maintain structural integrity under pressure or impact, effectively protecting the internal insulation enclosure 300 from damage. EPE has slightly lower cushioning and insulation properties, but it is less expensive and easier to process, making it more suitable for manufacturing large temperature control boxes. In a further embodiment of this application, the volume of the temperature control box is approximately 96L or more, therefore, EPE is preferably used as the material for the protective enclosure 200. It should be noted that the protective enclosure 200, in addition to its protective function, also provides some thermal insulation.

[0027] The insulation panels are preferably made of VIP (vacuum insulation panels). VIP panels have extremely low thermal conductivity, which can significantly improve the thermal insulation performance of the insulation box 300. In addition, VIP panels are thinner and lighter, which can effectively reduce the volume occupied by the insulation box 300 under the same insulation requirements and improve space utilization.

[0028] It should be noted that, as Figure 1 As shown, to avoid insufficient overall strength due to the use of EPE material in the protective enclosure 200, the temperature control box of this application also includes a reinforcing enclosure 100. The reinforcing enclosure 100 defines a first receiving cavity, within which the protective enclosure 200 is located. The reinforcing enclosure 100 is made of rigid plastic or metal, possessing high structural strength and load-bearing capacity, effectively improving the overall pressure resistance of the temperature control box. The first receiving cavity is adapted to the shape of the protective enclosure 200, allowing the protective enclosure 200 to be tightly embedded within the reinforcing enclosure 100, further enhancing the stability of the overall structure.

[0029] It should be noted that, such as Figure 2As shown, the reinforced enclosure 100 includes a first bottom wall 101 and multiple first side walls 102. The first bottom wall 101 and the first side walls 102 enclose a first accommodating cavity. To further enhance the structural strength of the reinforced enclosure 100, the reinforced enclosure 100 also includes a support frame 110. The support frame 110 includes a first main body 111 and a second main body 112. The first main body 111 is disposed on the first side wall 102, and the second main body 112 is disposed on the first bottom wall 101. The two are connected to each other to form an integral support structure, which can play a structural reinforcement role for the reinforced enclosure 100, improve its load-bearing capacity and deformation resistance, and thus form a stable support structure on the outside of the protective enclosure 200, reducing the risk of deformation and damage to the protective enclosure 200.

[0030] In such Figure 2 In the illustrated embodiment, the support frame 110 is disposed on the inner wall of the reinforced box 100. In other embodiments, the support frame 110 may also be disposed on the outer wall of the reinforced box 100. It is understood that, to avoid occupying excessive space, the reinforced box 100 is relatively thin; therefore, the support frame 110 serves to structurally reinforce the reinforced box 100. The support frame 110 can locally increase the thickness of the reinforced box 100, thereby giving the reinforced box 100 better load-bearing capacity and resistance to deformation.

[0031] For example, such as Figure 2 As shown, the reinforced housing 100 includes four first side walls 102, which are arranged in pairs facing each other. Each pair of facing first side walls 102 has a handle 103 extending through both the inner and outer sides of the first side wall 102 to facilitate handling and movement of the temperature control box. The handles 103 are preferably located in the middle of the first side wall 102 to ensure even force application during handling and reduce the risk of deformation due to uneven force. It is understood that the handles 103 may affect the structural strength of the reinforced housing 100; therefore, the support frame 110 is positioned corresponding to the handles 103 to compensate for any weakening of the housing's structural strength caused by the handles 103.

[0032] Specifically, the support frame 110 includes two first main body parts 111, which are respectively located on two opposite first sidewalls 102, and the first main body parts 111 are provided with through holes communicating with the handle part 103.

[0033] Furthermore, in addition to supporting and protecting the protective enclosure 200, the reinforced enclosure 100 also serves to limit the movement of the protective enclosure 200. Specifically, such as... Figure 2As shown, the reinforced enclosure 100 also includes a third cover 130 and a third enclosure 140. The third enclosure 140 defines a chamber for housing the protective enclosure 200. One side of the third cover 130 is fixedly connected to the third enclosure 140, and the other side is detachably connected to the third enclosure 140. The reinforced enclosure 100 also includes a first fastener 120, which can be a flexible structure such as a strap or rope. When the third cover 130 closes onto the opening of the third enclosure 140 to form a closed chamber, as... Figure 3 As shown, the first fixing member 120 can be wrapped around the outside of the third box cover 130, and the two ends of the first fixing member 120 pass through the handle part 103 and are connected to the third box body 140, thereby fixing the first fixing member 120 and confining the protective box body 200 within the reinforced box body 100.

[0034] Furthermore, the temperature control box also includes a second fixing member 150, which is also wrapped around the outside of the third box cover 130. Both ends of the second fixing member 150 are connected to the inner wall of the outer casing 400, thereby further improving the connection stability of the reinforced box 100 and reducing the probability of the protective box 200 detaching from the reinforced box 100 and the insulation box 300 detaching from the protective box 200 in the event of a drop or inversion. This also achieves the connection and fixation of the reinforced box 100 and the outer casing 400. Moreover, the arrangement of the first fixing member 120 and the second fixing member 150 not only strengthens and fixes the reinforced box 100 but also strengthens and fixes the overall structure.

[0035] In addition, in such Figure 3 In the illustrated embodiment, two first fasteners 120 and two second fasteners 150 are provided, and the first fasteners 120 and the second fasteners 150 are arranged intersectingly. It should be explained that the two ends of the second fasteners 150 can be detachably connected to the inner wall of the outer casing 400 by Velcro or by other means such as snap-fit ​​connections.

[0036] In some embodiments, such as Figure 9 As shown, the insulated box 300 includes a first box body 301, a first bottom cover 303, and a first lid 302. The first box body 301 has a hollow structure with open ends. The first bottom cover 303 and the first lid 302 are respectively installed on both ends of the first box body 301 to form a third accommodating cavity for accommodating items to be shipped. Based on the above, the insulated box 300 is formed by splicing insulated panels, wherein the insulated panels include a first insulated panel 310 and a second insulated panel 320. Multiple first insulated panels 310 are spliced ​​to form the first box body 301, and the second insulated panel 320 serves as the first bottom cover 303 and / or the first lid 302, connected to both ends of the first box body 301.

[0037] Furthermore, such as Figure 9 As shown, the first bottom cover 303 and the first box cover 302, along with the projection area along the vertical direction, can completely cover each of the first insulation panels 310 of the first box body 301.

[0038] Understandably, after multiple first insulation panels 310 are spliced ​​to form the first housing 301, in order to fix it into a whole and prevent relative displacement between the individual first insulation panels 310 that could lead to a loose housing structure, the first housing 301 is also equipped with pre-installed fasteners 330. These pre-installed fasteners 330 can be flexible components such as packing straps or ropes, which can be wrapped around the outside of each first insulation panel 310 to bind and fix them, ensuring the stability of the overall structure. The width of the pre-installed fasteners 330 can be adapted to the width of the first insulation panels 310, or, for example... Figure 4 As shown, the width of the pre-fitting member 330 can be smaller than the width of the first insulation board 310. By setting multiple pre-fitting members 330, the first insulation board 310 can be uniformly fixed. Alternatively, during the winding process, the pre-fitting member 330 is spirally wound around the outside of the first insulation board 310 to expand its contact area with the first insulation board 310.

[0039] Furthermore, the insulation box 300 formed by this type of splicing is prone to deformation or misalignment at the splice joints when subjected to impact, affecting the overall structural stability. Therefore, the insulation box 300 is also equipped with multiple reinforcing members 340, which are shaped as follows: Figure 6 The L-shaped structure shown covers the corner joints of the side walls of the insulation box 300. Specifically, the reinforcing member 340 includes intersecting first side plates 341 and second side plates 342. Preferably, the intersection angle of the first side plates 341 and second side plates 342 is determined according to the shape of the insulation box 300. In this embodiment, the insulation box 300 is a cubic structure, so the intersection angle of the first side plates 341 and second side plates 342 is 90 degrees to fit the right-angled corners of the insulation box 300. The first side plates 341 and second side plates 342 of the reinforcing member 340 are respectively attached to the outer surfaces of two adjacent first insulation boards 310, thereby enhancing the structural strength of the joint corners and preventing deformation or misalignment under external force. In addition, the reinforcing member 340 is made of rigid materials, such as plastic, metal, or composite panels, which can effectively disperse external impact forces and improve the overall compressive strength of the insulation box 300.

[0040] It should be noted that during installation, the reinforcing member 340 is first pre-fixed to the side wall splicing corner of the insulation box 300 by means of double-sided adhesive. Then, at least one more fixing strap can be wrapped around the outside of the insulation box 300. The fixing strap can be a flexible material such as plastic strap or rope. It is wrapped around the outside of the reinforcing member 340 to further tighten the various plates of the insulation box 300, so as to further enhance the structural stability of the insulation box 300.

[0041] Furthermore, if the first insulation board 310 is a VIP insulation board, the insulation effect will be greatly reduced because VIP material is prone to breakage upon impact. Based on the above, some surfaces of the insulation box 300 are covered and protected by pre-fixed parts 330, reinforcing parts 340, etc., but some surfaces are still exposed and prone to breakage upon impact. Therefore, the exposed parts of the insulation box 300 need to be protected. For example, the top surface of the first box 301, the inner wall surface of the first box 301, the inner wall surface of the first box cover 302, etc., protective parts made of PET material or other materials are attached to these exposed surfaces to improve the stability of the insulation effect of the insulation box 300.

[0042] Furthermore, the individual first insulation panels 310 abut against each other. For example... Figure 5 , Figure 6 and Figure 9 As shown, each of the first insulation panels 310 constituting the first housing 301 includes a first inner side surface 311 facing the third accommodating cavity, and a first end surface 312 adjacent to the first inner side surface 311, such as... Figures 5 to 6 As shown, the first end face 312 refers to the end face of the first insulation board 310 along the circumferential direction of the first housing 301. Two adjacent first insulation boards 310 are arranged vertically, with the first end face 312 of one first insulation board 310 abutting against the first inner side surface 311 of the other first insulation board 310. This arrangement ensures that each first insulation board 310 abuts against the first inner side surface 311 of the preceding first insulation board 310, and its first inner side surface 311 is abutted against by the first end face 312 of the following first insulation board 310, thereby forming a stable structure that supports each other.

[0043] In some embodiments, such as Figure 7 As shown, the protective housing 200 includes a second housing 201 and an installation component for mounting the thermometer. It should be noted that since the protective housing 200 of this application is made of EPE material, the structural strength of this material is relatively low, and the thermometer cannot be directly fixed to the second housing 201 by means of threaded connection or snap-fit. Therefore, the installation component is needed to achieve a stable installation of the thermometer.

[0044] The mounting assembly includes a first mounting member 210 located on the outer side of the second housing 201 and a second mounting member 220 located on the inner side of the second housing 201, with the first mounting member 210 and the second mounting member 220 disposed opposite to each other. The mounting assembly also includes a connector 230 passing through the side wall of the second housing 201, with its two ends respectively fixedly connected to the first mounting member 210 and the second mounting member 220, thereby clamping the second housing 201 between the first mounting member 210 and the second mounting member 220, so that the first mounting member 210 and the second mounting member 220 are fixed to the second housing 201. Understandably, compared to directly fixing the thermometer to the second housing 201 via threaded connectors, the connection between the threaded connectors and the second housing 201 is prone to problems such as loose connection or detachment due to the characteristics of EPE material. However, by setting the first mounting part 210 and the second mounting part 220 to clamp each other, not only can the pressure of the mounting components on the second housing 201 be evenly distributed, but the stability of the thermometer installation can also be effectively improved, avoiding loosening or detachment caused by external vibration or temperature changes.

[0045] Understandably, the thermometer can be mounted on the first mounting component 210. The connection method between the thermometer and the first mounting component 210 can be threaded, snap-fit, adhesive, etc., as long as the thermometer can be fixed in place.

[0046] In some embodiments, such as Figure 8 As shown, the protective enclosure 200 is formed by splicing multiple foam material panels and securing them together with packing straps, binding straps, etc., to form an integral structure. The splicing method can be referenced from the first insulation board 310, where the end face of one of two adjacent foam material panels abuts against the inner side of the other foam material panel, and they are connected in this way to form the second enclosure 201 of the protective enclosure 200. In... Figure 8 In the illustrated embodiment, the second cover 202 of the protective box 200 is integrally connected to the first cover 302 of the insulated box 300, thereby enabling the protective box 200 and the insulated box 300 to open and close synchronously, simplifying the steps of opening and closing the temperature control box. Furthermore, the first cover 302 of the insulated box 300, the second cover 202 of the protective box 200, and the third cover 130 of the reinforcing box 100 are integrally connected, thereby enabling the covers of the reinforcing box 100, the protective box 200, and the insulated box 300 to open and close synchronously.

[0047] Furthermore, such as Figure 9As shown, the first cover 302 of the insulated box 300 is made of two second insulation boards 320 of different sizes glued together. The inner second insulation board 320 forms a raised structure compared to the outer second insulation board 320. When the first cover 302 is closed, the inner second insulation board 320 will be inserted into the first box 301, thereby improving the sealing of the insulated box 300 and avoiding the risk of cold leakage caused by the displacement of the first cover 302 during transportation.

[0048] 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 reinforced box 100 from being worn due to long-term friction, an outer casing 400 is often fitted over the reinforced 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 1 As shown, the outer packaging box 400 includes a fourth box body 401 and a fourth box cover 402. The fourth box body 401 and the fourth box cover 402 are detachably connected to facilitate the replacement of the fourth box cover 402. For example, in some usage scenarios, logistics labels often need to be attached to the outermost top surface of the entire temperature-controlled box, that is, to the fourth box cover 402 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 fourth box cover 402 of the outer packaging box 400 after the label is replaced, affecting the appearance and secondary use. To solve this problem, the fourth box cover 402 of the outer packaging box 400 is designed as a replaceable structure, which is detachably connected to the fourth box body 401 by means of buckles, magnets, zippers or Velcro, so as to facilitate the replacement of the new fourth box cover 402 to maintain a clean appearance, while not affecting the reusability of the temperature-controlled box.

[0049] In addition, in conjunction with the foregoing, corresponding to the area in the protective enclosure 200 where the thermometer is located, the fourth enclosure 401 of the outer enclosure 400 is provided with a transparent viewing window so that the user can view the thermometer reading through the viewing window. It is understood that the reinforced enclosure 100 also has an opening to expose the thermometer.

[0050] In such Figure 1 In the illustrated embodiment, the interior of the insulation box 300 also includes a cold storage box, which is formed by splicing multiple ice blocks. The number and layout of the ice blocks can be flexibly adjusted according to requirements such as insulation temperature zone and insulation duration to achieve optimal insulation performance. Each ice block is quickly assembled using methods such as abutment, snap-fit ​​connection, or magnetic connection, and can be disassembled and stored when not in use for easy storage and transportation. For example, as... Figure 1 As shown, each ice floe has a sloping side, and the sloping sides of adjacent ice floes abut against each other to achieve the abutment and limiting of each ice floe.

[0051] 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.
