Description

Passive containers for storing and transporting temperature-sensitive items

[0001] The present invention relates to a passive container for storing and transporting temperature-sensitive items.

[0002] The cold chain is a system that manages temperature-sensitive products and other items at appropriate temperatures throughout the entire process from production to consumption. It refers to a logistics system that ensures the stability and reliability of temperature-sensitive products. In particular, with the global pandemic, there has been a significant increase in public interest in vaccine development, and interest in cold chain systems for safely storing and distributing manufactured vaccines has grown significantly.

[0003] With growing global interest in the cold chain industry, research and development on containers to implement this concept is actively underway. Efforts are underway to develop high-performance containers capable of safely maintaining environmental conditions, such as temperature and humidity, within refrigerated / freezer containers, ensuring a fresh and safe environment for the logistics and distribution of products sensitive to environmental factors like temperature and humidity.

[0004] Due to their specific characteristics, certain products require strict maintenance of storage temperatures within a specific range during distribution and storage. For example, chemicals, pharmaceuticals, blood, and food products, whose properties irreversibly change above or below a certain critical temperature, require strict storage within a predetermined target temperature range.

[0005] Containers used in cold chain systems can be categorized into active and passive types. Active containers are equipped with mechanical systems powered by electrical energy and operate automatic temperature controllers to maintain product temperature. Active containers require battery charging before use and essential electrical outlet connections at key supply chain points.

[0006] These active containers are expensive to purchase, rent, operate, and maintain. Their large net weight also leads to significant air freight charges. Furthermore, the lack of solutions to address potential issues during transport, such as sudden power outages, makes it difficult to ensure product stability. To address this, high-capacity batteries for self-power supply are being considered. However, this increases the container's weight and poses additional challenges, such as the risk of fire.

[0007] The present invention is intended to solve the aforementioned problems, and aims to provide a passive container for storing and transporting temperature-sensitive items, which can improve insulation performance while ensuring convenience in assembling phase change materials and stability in fastening.

[0036] Fig. 1 is a perspective view illustrating a passive container for storing and transporting temperature-sensitive items according to an embodiment of the present invention. Fig. 2 is a perspective view schematically illustrating the interior of a passive container for storing and transporting temperature-sensitive items according to an embodiment of the present invention. Fig. 3 is a schematic drawing illustrating the shape of a vacuum insulation panel according to an embodiment of the present invention.

[0037] Referring to FIG. 1, a passive container (1) for storing and transporting temperature-sensitive goods according to an embodiment of the present invention (hereinafter referred to as a “passive container”) includes an insulating box (10) having a predetermined internal storage space and a door portion (70) connected to the insulating box (10) to open and close the storage space.

[0038] The insulation box (10) may include an upper surface (20), a lower surface (30), a rear surface (40), and side surfaces (50, 60). The upper surface (20), the lower surface (30), the rear surface (40), and the side surfaces (50, 60) may determine the outer shape of the insulation box (10). The insulation box (10) may include an internal receiving space that is open toward the front. The internal receiving space with the front surface open may be provided by a combination of the upper surface (20), the lower surface (30), the rear surface (40), and the side surfaces (50, 60). The outer shape of the insulation box (10) may have a hexahedral shape, but is not limited thereto. The upper surface (20) may be positioned upward. The lower surface (30) may be positioned downward. The rear surface (40) may be positioned rearward and may be connected to the upper surface (20) and the lower surface (30). The side portions (50, 60) include a left side portion (50) and a right side portion (60). The left side portion (50) is located on the left side and connected to the upper side portion (20), the lower side portion (30), and the rear side (40), and the right side portion (60) is located on the right side and can be connected to the upper side portion (20), the lower side portion (30), and the rear side (40). Temperature-sensitive items such as chemicals and pharmaceuticals can be accommodated in the accommodation space.

[0039] The door part (70) is connected to the insulation box (10) and can open and close the internal storage space. For example, the door part (70) can be hinge-connected to either the left side part (50) or the right side part (60) and can be provided to rotate around the hinge, and the user can selectively perform the opening and closing operations of the internal storage space by controlling the door part (70).

[0040] Referring further to FIGS. 2 and 3, the upper surface (20), the lower surface (30), the rear surface (40), the side surfaces (50, 60) and the door surface (70) may include a vacuum insulation panel (81) for insulation, an outer reinforcing member (83) disposed outside the vacuum insulation panel (81), and a transparent member (85) disposed inside the vacuum insulation panel (81). The vacuum insulation panels (81) of the upper surface (20), the lower surface (30), the rear surface (40) and the side surfaces (50, 60) may be connected to each other. The outer reinforcing members (83) of the upper surface (20), the lower surface (30), the rear surface (40) and the side surfaces (50, 60) may be connected to each other. The transparent members (85) of the upper surface (20), lower surface (30), rear surface (40) and side surfaces (50, 60) can be connected to each other.

[0041] The vacuum insulation panel (81) may include multiple segmented panels (82) divided along one direction. Considering the ease of the manufacturing process and material properties, the vacuum insulation panel (81) may be formed by dividing into multiple pieces and then assembled. The segmented segmented panels (82) may be mutually fixed using an adhesive, but are not limited thereto.

[0042] At least one end of the split panels (82) may include an inclined surface (82a). The inclined surfaces (82a) of adjacent split panels (82) can secure a longer heat transfer path compared to a vertical surface. Accordingly, there is an advantage of being able to increase the insulation performance of the assembled vacuum insulation panel (81). For example, the vacuum insulation panel (81) may include a first split panel (82b) and a second split panel (82c) that are sequentially arranged in parallel along one direction and have an inclined surface (82a). In this case, the first split panel (82b) may have a trapezoidal cross-sectional shape, and the second split panel (82c) may have a parallelogram cross-sectional shape.

[0043] The outer reinforcing member (83) may be selected from a material having excellent rigidity and cushioning properties, as well as excellent heat resistance and insulation properties. For example, the outer reinforcing member (83) may include any one selected from among EPP (Expanded Polypropylene), GRP (Glass Fiber Reinforced Plastic), FRP (Fiber Reinforced Polymer), GRE (Glass Reenforce Epoxy), and SUS (Steel Use Stainless), but is not limited thereto. Alternatively, the outer reinforcing member (83) may have a structure in which multiple layers are laminated. For example, the outer reinforcing member (83) may have a structure in which one selected from among EPP (Expanded Polypropylene), GRP (Glass Fiber Reinforced Plastic), FRP (Fiber Reinforced Polymer), GRE (Glass Reenforce Epoxy), and SUS (Steel Use Stainless) having a predetermined rigidity is laminated on one side and the other side with one selected from among grommet, mineral wool, and Styrofoam, which are materials with excellent insulation performance, interposed therebetween, but is not limited thereto.

[0044] The transparent member (85) may include a material having a predetermined rigidity to protect the vacuum insulation panel (81) from the inside, and a predetermined transparency to allow the vacuum insulation panel (81) to be checked for defects or damage from the inside. The transparent member (85) may be any one of polycarbonate (PC), polyethylene terephthalate (PET), and acrylic, but is not limited thereto.

[0045] The upper surface (20), lower surface (30), rear surface (40), side surfaces (50, 60), and door portion (70) may further include an inner reinforcing member (87) disposed on the inner side of the transparent member (85). The inner reinforcing member (87) may protect the vacuum insulation panel (81) and the transparent member (85) from the inner side. A receiving portion (100, 150), which will be described later, may be fixed to the inner reinforcing member (87). The inner reinforcing member (87) may include a material having a predetermined rigidity so that the receiving portion (100, 150) can stably maintain a fixed state. The inner reinforcing member (87) may include any one selected from GRP (Glass fiber reinforced plastic), FRP (Fiber reinforced polymer), GRE (Glass reinforce epoxy), acrylic, and aluminum, but is not limited thereto. The inner reinforcing member (87) may be formed of different materials depending on the location. For example, the inner reinforcing members (87) of the upper surface (20), lower surface (30), rear surface (40), and side surfaces (50, 60) may include a metal material such as aluminum (Al), and the inner reinforcing member (87) of the door portion (70) may include GRP (Glass fiber reinforced plastic).

[0046] The inner reinforcing member (87) may include at least one through hole (88) penetrating the thickness. The through hole (88) may expose at least a portion of the transparent member (85). The through hole (88) may be a portion through which a user visually checks whether the vacuum insulation panel (81) is defective or damaged. The through hole (88) may be positioned so as not to overlap with the inclined surface (82a) formed on the vacuum insulation panel (81). This may mean that the insulation performance is improved by securing a longer heat transfer path compared to a structure in which the through hole (88) and the inclined surface (82a) overlap.

[0047] FIG. 4 is a drawing for explaining a first receiving portion and a fastening operation of the first receiving portion and the case according to an embodiment of the present invention. FIG. 5 is a drawing for explaining a support plate of a door portion according to an embodiment of the present invention.

[0048] Referring further to FIG. 4, a passive container (1) according to an embodiment of the present invention may include a receiving portion (100, 150) for detachably fixing at least one case (200). The receiving portions (100, 150) may include a first receiving portion (100) and a second receiving portion (150). The case (200) may include a temperature-maintaining material. The temperature-maintaining material may include a material for reducing thermal conductivity. For example, the temperature-maintaining material may be a phase change material (PCM).

[0049] The first receiving portion (100) may be fixed to the inner side of at least one of the left side portion (50), the right side portion (60), and the door portion (70). The first receiving portion (100) may include a receiving space for detachably receiving at least one case (200). The case (200) may be slidably fastened to the first receiving portion (100) along a first direction. A plurality of cases (200) may be received in the first receiving portion (100), and the plurality of cases (200) may be sequentially stacked along the first direction within the first receiving portion (100). For example, the first direction may correspond to the up-down direction (or the direction of gravity).

[0050] The first receiving portion (100) may be provided in multiple numbers. That is, multiple first receiving portions (100) may be positioned in at least one of the left side portion (50), the right side portion (60), and the door portion (70), and the multiple first receiving portions (100) may be arranged at a predetermined interval along a second direction (e.g., left-right direction) intersecting the first direction.

[0051] The first receiving portion (100) may include a pair of first rails (110) and second rails (120). The first rails (110) and second rails (120) may extend in parallel along a first direction and may be arranged to be spaced apart from each other in a second direction. The first rails (110) and second rails (120) may cover one side and the other side of the case (200), respectively, to allow the sliding motion of the received case (200) in the first direction and may restrict or limit the sliding motion in the second direction to a preset range. The first direction may correspond to the width direction of the case (200), and the second direction may correspond to the length direction of the case (200). One end (or the upper end) of the first rail (110) and the second rail (120) may be opened to allow the withdrawal of the case (200), but is not limited thereto.

[0052] The first rail (110) and the second rail (120) may include a protrusion for selectively preventing the case (200) from entering or exiting in a third direction in response to the case (200) moving in the first direction. The third direction may correspond to the thickness direction of the case (200).

[0053] The first rail (110) may include a first-first body (111) covering one side of the case (200), and a first-second body (113) extending from the first-first body (111) to cover at least a portion of the front surface of the case (200). The second rail (120) may include a second-first body (121) covering the other side of the case (200), and a second-second body (123) extending from the second-first body (121) to cover at least a portion of the front surface of the case (200).

[0054] A movement path may be provided by the first rail (110) and the second rail (120) to allow the sliding motion of the received case (200) in the first direction. The first-first body (111) and the second-first body (121) may restrict and limit the movement of the case (200) in the second direction. The first-second body (113) and the second-second body (123) may structurally restrict the movement of the case (200) in the third direction through their shapes. For this purpose, the first-second body (113), the second-second body (123), and the case (200) may include a protruding portion.

[0055] More specifically, the first-second body (113) may include a first concave portion (114) and a first convex portion (115) that are sequentially and alternately arranged along the first direction. The second-second body (123) may include a second concave portion (124) and a second convex portion (125) that are sequentially and alternately arranged along the first direction. The number of the first concave portion (114), the first convex portion (115), the second convex portion (124), and the second convex portion (125) may be preselected as needed.

[0056] The case (200) may include a first case protrusion (211) and a first case ridge (213) arranged on one side. The first case protrusion (211) and the first case ridge (213) may each be provided one or more times, and when there are multiple first case protrusions (211) and first case ridges (213), they may be arranged alternately. The first case protrusion (211) and the first case ridge (213) may correspond to the first ridge (114) and the first iron portion (115), respectively. The case (200) may include a second case protrusion (221) and a second case ridge (223) arranged on the other side. The second case iron part (221) and the second case yoke (223) may be provided one or more times, and when there are multiple second case iron parts (221) and second case yoke (223), they may be arranged alternately. The second case iron part (221) and the second case yoke (223) may correspond to the second yoke (124) and the second iron part (125), respectively.

[0057] The case (200) may be allowed to be introduced into the first receiving portion (100) along the third direction. At this time, the first case portion (211), the first case yoke (213), the second case yoke (221), and the second case yoke (223) may be overlapped along the third direction on the first yoke (114), the first yoke (115), the second yoke (124), and the second yoke (125), respectively.

[0058] The received case (200) may be restricted from being withdrawn from the first receiving portion (100) along the third direction. At this time, the first case portion (211), the first case yoke (213), the second case portion (221), and the second case yoke (223) may be overlapped with the first portion (115), the first yoke (114), the second portion (125), and the second yoke (124) along the third direction, respectively.

[0059] By having such a structure, the assembly of the case (200) can be easily performed as follows, and the disassembly operation can be easily performed in reverse order. (Assembly method) ① A plurality of cases (200) are prepared. ② One case (200) is introduced into the receiving space of the first receiving portion (100) along the third direction in a state where the main portion and the main portion of the case (200) are respectively matched with the main portion and the main portion of the first rail (110) and the second rail (120). ③ One case (200) is moved downward along the first direction and placed. Preferably, the first direction is the direction of gravity, so that the user can easily assemble the case (200) without applying a large force. ④ Other cases (200) can be introduced into the receiving space of the first receiving portion (100) in the same manner as the previous case (200), and can be sequentially placed on the cases (200) placed in advance. ⑤ In a state where the cases (200) are stacked, the main and iron portions of the cases (200) can be maintained in a state of overlapping with the main and iron portions of the first rail (110) and the second rail (120) along the third direction, respectively, and thus unwanted detachment of the cases (200) can be prevented.

[0060] The case (200) may further include one or more grip holes (230) penetrating the thickness. The grip holes (230) may be a portion that a user grips when carrying the case (200) or attaching it to a receiving portion (100, 150).

[0061] The first receiving portion (100) may include a support plate (130, 140) that supports the case (200) from below. The support plate (130, 140) may be fixed to at least one of the left side portion (50), the right side portion (60), and the door portion (70) to which the first rail (110) and the second rail (120) are fixed. And / or, the support plate (130, 140) may be fixed to the lower portion (30). The support plate (130, 140) may be connected to the other end (or lower end) of the first rail (110) and the second rail (120), but is not limited thereto.

[0062] Meanwhile, referring further to FIG. 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 may be positioned to substantially contact the upper surface (31) of the lower portion (30) (including cases where there is a predetermined tolerance) or include a preset gap. The preset gap may be set to within 0.5 mm to 1 cm, and preferably may be set to 0.5 mm to 1 mm or less. If necessary, a buffer member (not shown) that contacts the lower surface of the support plate (140) when the door portion (70) is closed may be further formed on the lower portion (30).

[0063] Since the support plate (140) located on the door part (70) is fixed only to the door part (70), deformation or breakage may occur due to the load of the cases (200) provided for a long period of time when multiple cases (200) are stacked, and thus, the door part (70) may not open or close properly or the cases (200) may come out of their positions. The passive container (1) according to the embodiment of the present invention has the advantage of ensuring product reliability and stability because the support plate (140) can be supported by the lower surface (30) when the door part (70) is closed, and thus deformation and breakage can be prevented or minimized.

[0064] The second receiving portion (150) may be fixed to the inner side of the upper surface (20). The second receiving portion (150) may include a receiving space that detachably receives at least one case (200). The case (200) may be slidably fastened to the second receiving portion (150) along the front-rear direction. The second receiving portion (150) may include a receiving plate (160) and an auxiliary plate (170).

[0065] The receiving plate (160) is spaced apart from the upper surface (20) downwardly by a predetermined distance, and can support the case (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 surface (20), and may be provided in multiple pieces and spaced apart from each other by a predetermined distance in the lateral direction. The first auxiliary plate (171) may partition a receiving space of the cases (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 surfaces (50, 60) and the rear surface (40), and / or may extend along the side surfaces (50, 60) and the rear surface (40) and be fixed to the lower surface (30).

[0066] When multiple cases (200) are stacked, the receiving plate (160) may be deformed or broken due to the load of the cases (200) provided for a long period of time, and thus the cases (200) may be removed from their positions. The passive container (1) according to the embodiment of the present invention has the advantage of ensuring product reliability and stability, as deformation and breakage can be prevented or minimized because the receiving plate (160) can be supported by the auxiliary plate (170).

[0067] FIG. 6 is a drawing for explaining a first cover member according to an embodiment of the present invention.

[0068] Referring further to FIG. 6, the insulating box (10) may further include a first cover member (180). The first cover member (180) may cover the open ends of the upper surface (20), the lower surface (30), and the side surfaces (50, 60). The first cover member (180) may have a cross-section formed in the shape of the letter “ㄷ”, and may be fitted and fixed to the open ends of the upper surface (20), the lower surface (30), and the side surfaces (50, 60). If necessary, the first cover member (180) and the open ends of the upper surface (20), the lower surface (30), and the side surfaces (50, 60) may be fixed to each other through at least one fixing means.

[0069] The first cover member (180) covers the inner reinforcing member (87), the transparent member (85), the vacuum insulation panel (81), and the side surfaces of the outer reinforcing member (83), and one end may be bent to cover at least a portion of the inner surface of the inner reinforcing member (87), and the other end may be bent to cover at least a portion of the outer surface of the outer reinforcing member (83). The first cover member (180) may include, but is not limited to, any one selected from GRP (Glass fiber reinforced plastic) and FRP (Fiber reinforced polymer).

[0070] The first cover member (180) can secure a long heat transfer path by including at least two or more bends. Accordingly, it has the advantage of significantly improving the insulation performance of the assembled insulation box (10).

[0071] FIG. 7 is a drawing for explaining a second cover member according to an embodiment of the present invention.

[0072] Referring further to Fig. 7, the door portion (70) may further include a second cover member (183) that covers the edge of the door portion (70). In the door portion (70), the transparent member (85), the vacuum insulation panel (81), and the outer reinforcing member (83) can be stably received and fixed in place by the assembly structure of the second cover member (183) and the inner reinforcing member (87).

[0073] More specifically, the inner reinforcing member (87) of the door portion (70) covers the front surface of the transparent member (85), but can have one end bent to cover the sides of the transparent member (85), the vacuum insulation panel (81), and the outer reinforcing member (83). The second cover member (183) can cover at least a portion of the edge of the front surface of the outer reinforcing member (83), but can cover the sides of the outer reinforcing member (83) on the outside of the inner reinforcing member (87).

[0074] The inner reinforcing member (87) of the door portion (70) and the second cover member (183) can be mutually fixed by at least one fixing means. The fixing means can penetrate the inner reinforcing member (87) of the door portion (70) and the second cover member (183) so as to face the side of the outer reinforcing member (83) in the lateral direction. The fixing means can be provided to penetrate the inner reinforcing member (87) and the second cover member (183), but also to penetrate the outer reinforcing member (83), in order to increase the fastening strength. The fixing means can be a rivet, but is not limited thereto.

[0075] Figure 8 is a drawing for explaining a detachment prevention means according to an embodiment of the present invention.

[0076] Referring to Fig. 8, the insulation box (10) may further include at least one anti-separation means to guide the stacking motion of a plurality of passive containers (1) in the vertical direction or to prevent them from being moved out of their positions during transportation. The anti-separation means may include:

[0077] It may include a protrusion (190) formed on one of the upper surface (20) and the lower surface (30) and a concave portion (not shown) formed on the other. The detachment prevention means may be formed on the upper surface (20) and the lower surface (30), and preferably formed at the edge. The protrusion (190) and the concave portion may be formed on the upper surface (20) and the lower surface (30), respectively, corresponding to an imaginary line extending parallel to one direction (or, up and down direction). The one direction may correspond to a stacking direction. For example, it may include a first passive container and a second passive container stacked above the first passive container. During stacking, the transporter may fit the concave portion of the second passive container into the protrusion (190) formed on the upper portion of the first passive container.

[0078] When transporting temperature-sensitive items (by sea, air, etc.), multiple passive containers (1) may be used, and these may be stacked within a preset space. In this case, since multiple passive containers (1) must be stacked within a limited space, stacking in a vertical direction may be required.

[0079] Previously, when stacking passive containers vertically, there was no means to guide the stacking position, requiring the carrier to rely on their intuition. Furthermore, external forces generated during transport could cause unwanted movement of the stacked passive containers, potentially damaging temperature-sensitive items stored within the containers.

[0080] The passive container (1) according to an embodiment of the present invention has an anti-separation means in the insulating box (10), so that the stacking positions of a plurality of passive containers (1) can be easily confirmed and stacked in the correct positions, and movement due to external force during transportation can be reduced, thereby minimizing damage to the container itself and to temperature-sensitive items accommodated inside.

[0081] Meanwhile, the insulation box (10) may further include a third cover member (185) that covers the edges and corners of the adjacent upper surface (20), lower surface (30), rear surface (40), and side surfaces (50, 60). The third cover member (185) may reinforce the rigidity of the insulation box (10) by mutually fixing the adjacent upper surface (20), lower surface (30), rear surface (40), and side surfaces (50, 60). The third cover member (185) may include SUS (Steel Use Stainless), but is not limited thereto.

[0082] The detachment prevention means may be formed on the third cover member (185). That is, the protrusion (190) may be formed on the third cover member (185) located on the upper surface (20), and the concave portion may be formed on the third cover member (185) located on the lower surface (30). As the detachment prevention means is formed on the third cover member (185), the strength in response to external force may be significantly improved.

[0083] Figure 9 is a drawing for explaining a buffer member according to an embodiment of the present invention.

[0084] Referring further to FIG. 9, the passive container (1) according to an embodiment of the present invention may further include a buffer member (195) to buffer the impact between the door member (70) and the insulating box (10) when the door member (70) is opened and closed and to maintain airtightness. The buffer member (195) is fixed to the insulating box (10) and may be positioned in an area where the insulating box (10) and the door member (70) come into contact when the door member (70) is closed.

[0085] The buffer member (195) may be made of a porous material having buffering power, such as polyethylene (PE), polypropylene (PP), acrylic, and polyurethane (PU), but is not limited thereto. The buffer member (195) may include one or more buffer holes (196) extending along the length direction. The buffer holes (196) may be pressurized and sealed by the door part (70) and the insulation box (10) when the door part (70) is closed.

[0086] Conventionally, a buffer member (195) not provided with a buffer hole (196) is pressed by the door member (70) and the insulation box (10) when the door member (70) is closed, and thus is pushed to one side, resulting in a defective opening and closing of the door member (70) or a defect in maintaining airtightness. The passive container (1) according to an embodiment of the present invention has a buffer hole (196), thereby preventing a defective opening and closing of the door member (70) due to deformation of the buffer member (195) and having the advantage of ensuring airtightness.

[0087] It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the essential characteristics thereof. Therefore, the above detailed description should not be construed as limiting in any respect, but rather as illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the scope of equivalents of the present invention are intended to be included within the scope of the present invention.
