Description

Technical Field

[0001] This invention relates to a passive container for storing and transporting temperature-sensitive items. Background Technology

[0002] The cold chain is a system that manages temperature-sensitive goods at appropriate temperatures throughout the entire process from production to consumption. It refers to a logistics system that ensures the stability and reliability of these goods. Especially in the context of a global pandemic, with increased public focus on vaccine development, cold chain systems that ensure the safe storage and transportation of vaccines have received considerable attention.

[0003] With increasing global attention on the cold chain industry, research and development of related transport containers is booming. Specifically, to provide a fresh and safe environment for transporting or storing items sensitive to environmental factors such as temperature and humidity, the industry is dedicated to developing high-performance containers to safely maintain the temperature and humidity conditions within refrigerated / frozen containers.

[0004] Due to their characteristics, certain commodities require strict temperature control during transportation and storage. For example, chemicals, pharmaceuticals, blood, and food products will undergo irreversible changes in properties if the temperature exceeds or falls below a specific critical temperature. Therefore, the storage temperature must be strictly maintained within a predetermined target temperature range.

[0005] Containers used in cold chain systems can be divided into two categories: active and passive. Active containers refer to containers equipped with electrically driven mechanical systems that maintain product temperature by driving automatic temperature control devices. Active containers require battery charging before use and must be connected to a power outlet in key supply chain areas.

[0006] Such active containers require significant investment in procurement, leasing, operation, and maintenance, and incur high air freight costs due to their substantial weight. Furthermore, the lack of solutions to address issues such as sudden power outages during transport makes it difficult to ensure product safety. While methods to achieve self-powered operation using high-capacity batteries have been considered, these approaches introduce new problems such as increased weight and fire risks. Summary of the Invention

[0007] The problem the invention aims to solve

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a passive container for storing and transporting temperature-sensitive items, which improves thermal insulation performance while ensuring the ease of assembly and connection stability of phase change materials, etc.

[0039] Figure 1 This is a perspective view of a passive container for storing and transporting temperature-sensitive items according to an embodiment of the present invention. Figure 2 This is a schematic perspective view of the interior of a passive container for storing and transporting temperature-sensitive items according to an embodiment of the present invention. Figure 3 This is a schematic diagram showing the shape of a vacuum insulation panel according to an embodiment of the present invention.

[0040] See Figure 1 The passive container 1 (hereinafter referred to as "passive container") for storing and transporting temperature-sensitive items according to an embodiment of the present invention includes an insulated box 10 having a defined internal containment space and a door 70 connected to the insulated box 10 and opening and closing the containment space.

[0041] The heat insulation box 10 may include an upper part 20, a lower part 30, a rear part 40, and side parts 50 and 60. The upper part 20, lower part 30, rear part 40, and side parts 50 and 60 constitute the outer shape of the heat insulation box 10. The heat insulation box 10 may include a front-opening internal receiving space. The front-opening internal receiving space may be formed by a combination of the upper part 20, lower part 30, rear part 40, and side parts 50 and 60. The shape of the heat insulation box 10 may be cubic, but is not limited to this. The upper part 20 may be located at the top. The lower part 30 may be located at the bottom. The rear part 40 may be located at the rear and connected to the upper part 20 and the lower part 30. The side parts 50 and 60 include a left side part 50 and a right side part 60, wherein the left side part 50 is located on the left and connected to the upper part 20, lower part 30, and rear part 40, while the right side part 60 is located on the right and connected to the upper part 20, lower part 30, and rear part 40. The storage space can accommodate temperature-sensitive items such as chemicals and pharmaceuticals.

[0042] The door 70 is connected to the insulated box 10 and can open and close the internal storage space. For example, the door 70 can be connected to either the left side panel 50 or the right side panel 60, enabling rotational movement centered on the hinge. The user can selectively open and close the internal storage space by controlling the door 70.

[0043] Further reading Figure 2 and Figure 3 The upper part 20, lower part 30, rear part 40, side parts 50, 60, and door part 70 may include a vacuum insulation panel 81 for heat insulation, an outer reinforcing member 83 disposed on the outer side of the vacuum insulation panel 81, and a transparent member 85 disposed on the inner side of the vacuum insulation panel 81. The vacuum insulation panels 81 of the upper part 20, lower part 30, rear part 40, and side parts 50, 60 can be interconnected. The outer reinforcing members 83 of the upper part 20, lower part 30, rear part 40, and side parts 50, 60 can be interconnected. The transparent members 85 of the upper part 20, lower part 30, rear part 40, and side parts 50, 60 can be interconnected.

[0044] The vacuum insulation panel 81 may include segmented panels 82 divided into multiple parts along one direction. Considering the difficulty of the manufacturing process and the material properties, the vacuum insulation panel 81 may be assembled after being segmented and formed into multiple parts. The segmented panels 82 may be fixed together with adhesives, but are not limited to this method.

[0045] At least one end of the partition plate 82 may include an inclined surface 82a. The inclined surfaces 82a of adjacent partition plates 82, relative to the vertical surface, can ensure a longer heat transfer path. This can improve the thermal insulation performance of the assembled vacuum insulation panel 81. As an example, the vacuum insulation panel 81 may include a first partition plate 82b and a second partition plate 82c arranged side by side in one direction and having inclined surfaces 82a. In this case, the first partition plate 82b may have a trapezoidal cross-sectional shape, while the second partition plate 82c may have a parallelogram cross-sectional shape.

[0046] The outer reinforcing member 83 may be made of a material that combines excellent rigidity, cushioning, heat resistance, and thermal insulation. As an example, the outer reinforcing member 83 may include, but is not limited to, any material selected from expanded polypropylene (EPP), glass fiber reinforced plastic (GRP), fiber reinforced polymer (FRP), glass fiber reinforced epoxy (GRE), and stainless steel (SUS). Alternatively, the outer reinforcing member 83 may have a multilayer laminated structure. As an example, the outer reinforcing member 83 may consist of a material of predetermined rigidity selected from expanded polypropylene, glass fiber reinforced plastic (GRP), fiber reinforced polymer (FRP), glass fiber reinforced epoxy (GRE), and stainless steel (SUS), sandwiched between two sides of a material with excellent thermal insulation properties selected from glass wool, mineral wool, polystyrene foam, etc., and laminated together, but is not limited to this.

[0047] The transparent component 85 may include a material having a certain rigidity to protect the vacuum insulation panel 81 from the inside, while also having a certain transparency to allow inspection of defects and damage to the vacuum insulation panel 81 from the inside. The transparent component 85 may be one of, but is not limited to, polycarbonate (PC), polyethylene terephthalate (PET), and acrylic acid.

[0048] The upper part 20, lower part 30, rear part 40, side parts 50, 60, and door part 70 may further include an inner reinforcing member 87 disposed inside the transparent member 85. The inner reinforcing member 87 can protect the vacuum insulation plate 81 and the transparent member 85 from the inside. The inner reinforcing member 87 allows the receiving parts 100 and 150, described later, to be fixed thereon. The inner reinforcing member 87 may include a material with specified rigidity to stably maintain the receiving parts 100 and 150 in a fixed state. The inner reinforcing member 87 may include, but is not limited to, any material selected from glass fiber reinforced plastic (GRP), fiber reinforced polymer (FRP), glass fiber reinforced epoxy resin (GRE), acrylic (Acryl), and aluminum (Aluminum). The inner reinforcing member 87 may be made of different materials depending on its location. As an example, the inner reinforcement members 87 of the upper part 20, lower part 30, rear part 40 and side parts 50, 60 may include metal materials such as aluminum (Al), while the inner reinforcement members 87 of the door part 70 may include glass fiber reinforced plastic (GRP).

[0049] The inner reinforcement member 87 may include at least one through hole 88 extending through the thickness. The through hole 88 exposes at least a portion of the transparent member 85. The through hole 88 allows a user to visually inspect the vacuum insulation panel 81 for defects and damage. The through hole 88 may be configured not to overlap with the inclined surface 82a formed on the vacuum insulation panel 81. This means that compared to a structure where the through hole 88 overlaps with the inclined surface 82a, the heat transfer path can be extended, thereby improving insulation performance.

[0050] Figure 4 This is a schematic diagram illustrating the first receiving portion and the connection operation between the first receiving portion and the housing according to an embodiment of the present invention. Figure 5 This is a schematic diagram of the support plate of the door according to an embodiment of the present invention.

[0051] Further reading Figure 4 According to an embodiment of the present invention, the passive container 1 may include receiving portions 100 and 150 that detachably secure at least one housing 200. The receiving portions 100 and 150 may include a first receiving portion 100 and a second receiving portion 150. The housing 200 may include a temperature-maintaining material. The temperature-maintaining material may include a material for reducing heat flow. For example, the temperature-maintaining material may be a phase change material (PCM).

[0052] The first receiving portion 100 may be fixed to the inner side of at least one of the left side face 50, the right side face 60, and the door portion 70. The first receiving portion 100 may include a receiving space that can detachably receive at least one housing 200. The housing 200 may be slidably connected to the first receiving portion 100 along a first direction. The first receiving portion 100 may receive a plurality of housings 200, which may be stacked sequentially within the first receiving portion 100 along a first direction. For example, the first direction may correspond to the vertical direction (or the direction of gravity).

[0053] Multiple first receiving portions 100 may be provided. That is, multiple first receiving portions 100 may be provided at at least one of the left face 50, the right face 60 and the door portion 70, and the multiple first receiving portions 100 may be arranged at predetermined intervals along a second direction (e.g., the left-right direction) that intersects the first direction.

[0054] The first receiving portion 100 may include a pair of first guide rails 110 and second guide rails 120. The first guide rails 110 and second guide rails 120 extend side by side along a first direction and are spaced apart from each other along a second direction. The first guide rails 110 and second guide rails 120 respectively cover one side and the other side of the housing 200, which can constrain or limit the sliding movement of the housing 200 along the second direction while allowing sliding movement along the first direction. The first direction may correspond to the width direction of the housing 200, and the second direction may correspond to the length direction of the housing 200. One end (or the upper end) of the first guide rails 110 and second guide rails 120 is open to allow the housing 200 to be pulled out, but is not limited thereto.

[0055] The first guide rail 110 and the second guide rail 120 may include protrusions or recesses in the housing 200 that selectively block movement of the housing 200 in a third direction in response to movement of the housing 200 in the first direction. The third direction may correspond to the thickness direction of the housing 200.

[0056] The first guide rail 110 may include a first-1 body 111 covering one side of the housing 200, and a first-2 body 113 extending from the first-1 body 111 and covering at least a portion of the front portion of the housing 200. The second guide rail 120 may include a second-1 body 121 covering the other side of the housing 200, and a second-2 body 123 extending from the second-1 body 121 and covering at least a portion of the front portion of the housing 200.

[0057] The first guide rail 110 and the second guide rail 120 form a movement path that allows the housing 200 to slide along a first direction. The first-1 body 111 and the second-1 body 121 can constrain and limit the movement of the housing 200 along a second direction. The first-2 body 113 and the second-2 body 123 can restrict the movement of the housing 200 along a third direction through their shape and structure. For this purpose, the first-2 body 113, the second-2 body 123, and the housing 200 may include protrusions and recesses.

[0058] More specifically, the first-second body 113 may include a first recess 114 and a first protrusion 115 arranged alternately in sequence along a first direction. The second-second body 123 may include a second recess 124 and a second protrusion 125 arranged alternately in sequence along the first direction. The number of the first recess 114, the first protrusion 115, the second recess 124, and the second protrusion 125 may be pre-selected as needed.

[0059] The housing 200 may include a first housing protrusion 211 and a first housing recess 213 disposed on one side. One or more of the first housing protrusion 211 and the first housing recess 213 may be provided, and when there are multiple first housing protrusions 211 and first housing recesses 213, they may be arranged alternately. The first housing protrusion 211 and the first housing recess 213 may correspond to a first recess 114 and a first protrusion 115, respectively. The housing 200 may include a second housing protrusion 221 and a second housing recess 223 disposed on the other side. One or more of the second housing protrusion 221 and the second housing recess 223 may be provided, and when there are multiple second housing protrusions 221 and second housing recesses 223, they may be arranged alternately. The second housing protrusion 221 and the second housing recess 223 may correspond to a second recess 124 and a second protrusion 125, respectively.

[0060] The housing 200 can be introduced into the first receiving portion 100 along a third direction. At this time, the first housing protrusion 211, the first housing recess 213, the second housing protrusion 221 and the second housing recess 223 can overlap with the first recess 114, the first protrusion 115, the second recess 124 and the second protrusion 125 respectively along a third direction.

[0061] The housing 200 can be withdrawn from the first receiving portion 100 along a third direction. At this time, the first housing protrusion 211, the first housing recess 213, the second housing protrusion 221 and the second housing recess 223 can overlap with the first protrusion 115, the first recess 114, the second protrusion 125 and the second recess 124 respectively along a third direction.

[0062] With the aforementioned structure, the housing 200 can be easily assembled as follows, and disassembly can be easily performed in reverse order. (Assembly Method) ① Prepare multiple housings 200. ② With the protrusions and concave portions of one housing 200 respectively matching the concave portions and protrusions of the first guide rail 110 and the second guide rail 120, the housing 200 is introduced into the receiving space of the first receiving portion 100 along a third direction. ③ One housing 200 is moved downward along a first direction and stacked. Preferably, the first direction is the direction of gravity, so the user can easily assemble the housing 200 without applying a large force. ④ Other housings 200 can be introduced into the receiving space of the first receiving portion 100 in the same manner as the aforementioned housing 200, and can be stacked sequentially on top of the pre-stacked housings 200. ⑤ In the stacked state of the housings 200, the protrusions and concave portions of the housing 200 can be kept overlapping with the concave portions and protrusions of the first guide rail 110 and the second guide rail 120 along a third direction, thereby preventing the housings 200 from accidentally detaching.

[0063] The housing 200 may also include at least one gripping hole 230 extending through its thickness. The gripping hole 230 can serve as a gripping part for the user when the user moves the housing 200 or connects it to the receiving parts 100, 150.

[0064] The first receiving portion 100 may include support plates 130 and 140 supporting the housing 200 from below. Support plates 130 and 140 may be fixed to at least one of the left side portion 50, right side portion 60, and door portion 70 of the first guide rail 110 and the second guide rail 120. And / or, support plates 130 and 140 may also be fixed to the lower portion 30. Support plates 130 and 140 may be connected to the other end (or lower end) of the first guide rail 110 and the second guide rail 120, but are not limited thereto.

[0065] On the other hand, further reading Figure 5 The support plate 140 located on the door portion 70 faces the upper surface 31 of the lower portion 30 when the door portion 70 is closed, and is positioned in actual contact with the upper surface 31 of the lower portion 30 (including cases where specified tolerances exist) or includes a preset gap. The preset gap can be set within 0.5mm to 1cm, preferably less than or equal to 0.5mm to 1mm. If necessary, a buffer member (not shown) may also be formed on the lower portion 30 to contact the lower surface of the support plate 140 when the door portion 70 is closed.

[0066] Since the support plate 140 located at the door 70 is only fixed to the door 70, when multiple housings 200 are stacked, the long-term load on the housings 200 may cause deformation or breakage, resulting in opening and closing failure of the door 70 or misalignment of the housings 200. According to the passive container 1 of the present invention, when the door 70 is closed, the support plate 140 at the lower part 30 can prevent or minimize deformation and breakage, ensuring product reliability and stability.

[0067] The second receiving portion 150 may be fixed to the inner side of the upper portion 20. The second receiving portion 150 may include a receiving space that can be detachably received by at least one housing 200. The housing 200 may be slidably connected to the second receiving portion 150 in the front-rear direction. The second receiving portion 150 may include a receiving plate 160 and an auxiliary plate 170.

[0068] The receiving plate 160 may be arranged at specific intervals from the upper part 20 downwards, thereby supporting the housing 200 from below. The auxiliary plate 170 may include a first auxiliary plate 171 and a second auxiliary plate 173. The first auxiliary plate 171 connects the receiving plate 160 and the upper part 20, and may have multiple plates arranged at predetermined intervals along their respective lateral directions. The first auxiliary plate 171 may divide the receiving space of the housing 200. The second auxiliary plate 173 may support the receiving plate 160 from below. The second auxiliary plate 173 may be fixed to the side portions 50, 60 and the rear part 40, and / or extend along the side portions 50, 60 and the rear part 40 and be fixed to the lower part 30.

[0069] When multiple housings 200 are stacked, the receiving plate 160 bears the load of the housings 200 for a long time, which may cause deformation or breakage, resulting in the housings 200 deviating from their positioning. In the passive container 1 according to an embodiment of the present invention, the receiving plate 160 is supported by the auxiliary plate 170, thereby preventing or minimizing deformation and breakage, and ensuring product reliability and stability.

[0070] Figure 6 This is a schematic diagram of the first cover component according to an embodiment of the present invention.

[0071] Further reading Figure 6 The insulated box 10 may further include a first cover component 180. The first cover component 180 may cover the open ends of the upper part 20, the lower part 30, and the side parts 50, 60. The cross-section of the first cover component 180 may form a "U"-shaped structure, and it is kept fixed by fitting into the open ends of the upper part 20, the lower part 30, and the side parts 50, 60. As needed, the first cover component 180 and the open ends of the upper part 20, the lower part 30, and the side parts 50, 60 may be fixed to each other by at least one fixing device.

[0072] The first cover component 180 covers the sides of the inner reinforcing component 87, the transparent component 85, the vacuum insulation plate 81, and the outer reinforcing component 83. One end of the first cover component 180 is bent to cover at least a portion of the inner surface of the inner reinforcing component 87, and the other end is bent to cover at least a portion of the outer surface of the outer reinforcing component 83. The first cover component 180 may include, but is not limited to, any material selected from glass fiber reinforced plastic (GRP) and fiber reinforced polymer (FRP).

[0073] The first cover component 180 may include two or more bends to ensure a longer heat transfer path. Therefore, the thermal insulation performance of the assembled insulated box 10 can be significantly improved.

[0074] Figure 7 This is a schematic diagram of the second cover component according to an embodiment of the present invention.

[0075] Further reading Figure 7 The door portion 70 may also include a second cover member 183 covering the edge of the door portion 70. In the door portion 70, the transparent member 85, the vacuum insulation plate 81, and the outer reinforcement member 83 can be securely accommodated and fixed in the correct position through the assembly structure of the second cover member 183 and the inner reinforcement member 87.

[0076] More specifically, the inner reinforcement member 87 of the door 70 covers the front of the transparent member 85, with one end bent to cover the side of the transparent member 85, the vacuum insulation plate 81, and the outer reinforcement member 83. The second cover member 183 may cover at least a portion of the middle edge of the front of the outer reinforcement member 83, and may cover the side of the outer reinforcement member 83 outside the inner reinforcement member 87.

[0077] The inner reinforcing member 87 of the door portion 70 and the second cover member 183 can be fixed to each other by at least one fixing device. The fixing device can be in the lateral direction, facing the side of the outer reinforcing member 83, and passing through the inner reinforcing member 87 and the second cover member 183 of the door portion 70. To improve the connection strength, the fixing device can be configured to pass through the inner reinforcing member 87 and the second cover member 183 and simultaneously pass through the outer reinforcing member 83. The fixing device can be a rivet, but is not limited to this.

[0078] Figure 8 This is a schematic diagram of an anti-detachment device according to an embodiment of the present invention.

[0079] See Figure 8The insulated box 10 may also include at least one or more anti-detachment devices for guiding the stacking of multiple passive containers 1 in a vertical direction or preventing them from detaching from their correct positions during transport. The anti-detachment device may include a protrusion 190 formed at either the upper portion 20 or the lower portion 30, and a recess (not shown) formed at the other. The anti-detachment device is preferably formed on the upper portion 20 and the lower portion 30, and at their edges. The protrusion 190 and the recess may correspond to virtual lines extending in one direction (or vertical direction), formed on the upper portion 20 and the lower portion 30, respectively. One direction may correspond to the stacking direction. As an example, a first passive container and a second passive container stacked on top of the first passive container may be included. During stacking, transport personnel can engage the recess of the second passive container with the protrusion 190 formed on the upper part of the first passive container.

[0080] When transporting temperature-sensitive items (by sea, air, etc.), multiple passive containers 1 can be used and stacked within a pre-defined space. In this case, since multiple passive containers 1 need to be stacked within a limited space, they may need to be stacked vertically.

[0081] In existing technologies, when stacking passive containers, the lack of a device to guide the stacking position means that stacking relies on the sense of touch of the transport personnel. Furthermore, external forces generated during transport may cause unexpected displacement of the stacked passive containers, thereby damaging the temperature-sensitive items stored inside.

[0082] According to the embodiments of the present invention, the passive container 1 is equipped with an anti-detachment device on the heat-insulated box 10, which can easily confirm the stacking position of multiple passive containers 1 and stack them in the correct position, effectively reducing the displacement caused by external forces during transportation, thereby minimizing damage to the container itself and the temperature-sensitive items contained inside.

[0083] On the other hand, the insulation box 10 may also include a third cover member 185 that covers the edges and corners of adjacent upper portion 20, lower portion 30, rear portion 40, and side portions 50, 60. The third cover member 185 can enhance the rigidity of the insulation box 10 by mutually fixing adjacent upper portion 20, lower portion 30, rear portion 40, and side portions 50, 60. The third cover member 185 may include, but is not limited to, stainless steel (SUS).

[0084] An anti-detachment device may be formed on the third cover member 185. That is, a protrusion 190 may be formed on the third cover member 185 located on the upper part 20, while a recess may be formed on the third cover member 185 located on the lower part 30. Since the anti-detachment device is formed on the third cover member 185, the strength against external forces can be significantly improved.

[0085] Figure 9This is a schematic diagram of a buffer component according to an embodiment of the present invention.

[0086] Further reading Figure 9 According to an embodiment of the present invention, the passive container 1 may further include a buffer member 195 that can buffer the impact between the door 70 and the heat insulation box 10 and maintain airtightness when the door 70 is closed. The buffer member 195 is fixed to the heat insulation box 10 and may be disposed in the area that contacts the heat insulation box 10 and the door 70 when the door 70 is closed.

[0087] The cushioning component 195 may be made of a porous material with cushioning properties, such as, but not limited to, polyethylene (PE), polypropylene (PP), acrylic resin, and polyurethane (PU). The cushioning component 195 may include one or more cushioning holes 196 extending along its length. The cushioning holes 196 can be sealed by pressure applied by the door 70 and the insulation box 10 when the door 70 is closed.

[0088] In the prior art, the buffer component 195, which lacks the buffer hole 196, is squeezed to one side when the door 70 is closed due to the pressure exerted by the door 70 and the insulation box 10, resulting in opening and closing failures of the door 70 or a decrease in sealing performance. The passive container 1 according to the embodiment of the present invention, by providing the buffer hole 196, can prevent opening and closing failures of the door 70 caused by deformation of the buffer component 195 and maintain airtightness.

[0089] Those skilled in the art can implement the invention in other specific forms without departing from the spirit and essential features of the invention. Therefore, the detailed description above is not restrictive in all respects but is exemplary. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.
