[0038] In the existing logistics system, there is a metal frame for accommodating and transporting articles, the articles are accommodated in the metal frame, and the metal frame and the articles are transported to the destination together. In order to reduce the cost, the metal frame comprises a frame and a metal mesh arranged on the frame, and the above structure makes the metal frame completely without heat preservation function, and therefore cannot be applied to cold chain logistics.
[0039] For this purpose, please refer to Figures 1-5 The present application provides a heat preservation container, which comprises an outer supporting frame 10, a heat preservation inner core 20 and a connecting piece 30.
[0040] Please refer to Figure 1 And Figure 2 The outer supporting frame 10 can be directly selected from the common frame body in logistics, such as the metal frame suitable for ordinary logistics, so as to reduce the cost.
[0041] The outer support frame 10 has a cavity 10a, and the heat preservation inner core 20 is detachably arranged in the cavity 10a. The heat preservation inner core 20 has an inner cavity capable of heat preservation, and the cold-chain transported goods can be placed in the inner cavity and cooled by the heat preservation inner core 20.
[0042] The connecting piece 30 is used to detachably connect the heat preservation inner core 20 to the outer support frame 10, so as to limit the separation of the outer support frame 10 and the heat preservation inner core 20. It can be understood that the heat preservation inner core 20 can be connected to the outer support frame 10 through the connecting piece 30, so that the inner cavity wall of the outer support frame 10 supports the outer side wall of the heat preservation inner core 20. The heat preservation inner core 20 can be disconnected from the outer support frame 10 through the connecting piece 30, so that the inner cavity wall of the outer support frame 10 can be separated from the outer side wall of the heat preservation inner core 20.
[0043] The inner cavity wall of the outer support frame 10 can support the outer side wall of the heat preservation inner core 20. The size and shape of the cavity 10a can be matched with the heat preservation inner core 20, so that after the heat preservation inner core 20 is placed in the cavity 10a, the outer side wall of the heat preservation inner core 20 can be supported by the inner cavity wall of the outer support frame 10. It can be understood that the inner cavity wall of the outer support frame 10 supports the outer side wall of the heat preservation inner core 20, so that the two have a certain support strength and heat preservation effect as a whole, so that the cold-chain transported goods can be accommodated and heat preserved.
[0044] In the above embodiment, the goods can be placed in the outer support frame 10 and applied to normal temperature logistics, and in the cold-chain transportation scene, the heat preservation inner core 20 is arranged in the cavity 10a of the outer support frame 10, and the connecting piece 30 detachably connects the heat preservation inner core 20 to the outer support frame 10. At this time, the cold-chain transported goods can be placed in the inner cavity of the heat preservation inner core 20 for heat preservation, so as to be applied to the cold-chain transportation scene. In this way, the outer support frame 10 can be applied to cold-chain transportation, and the cost of the heat preservation container for cold-chain transportation is also reduced.
[0045] The specific structure of the heat preservation inner core 20 will be described below. Figures 3-5
[0046] In some embodiments, the heat preservation inner core 20 includes an inner core body 21, and the inner core body 21 includes a plurality of heat preservation plates 211. It can be understood that the heat preservation plate 211 has a heat preservation function, that is, it can block the heat exchange between the inner cavity and the outside. The plurality of heat preservation plates 211 can be connected in a fixed manner to enclose the inner cavity.
[0047] In some embodiments, the plurality of thermal insulation plates 211 are detachably arranged to form the inner cavity. Since the plurality of thermal insulation plates 211 are detachably arranged to form the inner cavity, the thermal insulation inner core 20 can be transported in an unconnected form, i.e. by transporting the stack of thermal insulation plates 211, to avoid occupying space by the inner cavity, thereby reducing the overall size and saving transportation space. It should be noted that the stack of thermal insulation plates 211 is transported separately from the thermal insulation inner core 20, and the cold-chain goods are not transported.
[0048] In some embodiments, the thermal insulation inner core 20 further comprises an outer cover 22, which is arranged outside the inner core body 21, and the material of the outer cover 22 is a flexible material. The outer cover 22 can better play a sealing role to prevent air flow from flowing out of the gap between adjacent thermal insulation plates 211, thereby achieving a certain thermal insulation effect. In addition, the material of the outer cover 22 is a flexible material, so that the overall size can be reduced by folding to save transportation space.
[0049] The outer cover 22 can be made of a material with a reflective thermal insulation layer to further improve the thermal insulation effect.
[0050] In order to further improve the stability of the detachable connection of the thermal insulation plates 211, the size and shape of the outer cover 22 can be adapted to the inner core body 21, so that after the inner core body 21 is placed in the outer cover 22, the outer cover 22 can limit the movement of each thermal insulation plate 211 away from the remaining thermal insulation plates 211, that is, to provide a constraint so that each thermal insulation plate 211 maintains the current connection state.
[0051] In order to facilitate the product to be sent into the inner cavity, the inner core body 21 can comprise a door plate 212, which can be switched to an open state or a closed state. In the open state, the product is sent into the inner cavity, and in the closed state, the product in the inner cavity is kept warm.
[0052] In order to keep the door plate 212 in the closed state, in some embodiments, the thermal insulation container comprises at least one set of connection assemblies 40, and each connection assembly 40 comprises a first connecting piece 41 and a second connecting piece 42.
[0053] The first connecting piece 41 of one set of connection assemblies 40 is arranged on the door plate 212, and the second connecting piece 42 of the set of connection assemblies 40 is arranged on the outer cover 22. In the closed state, the second connecting piece 42 can be detachably connected with the first connecting piece 41 to keep the door plate 212 in the closed state. By separating the first connecting piece 41 from the second connecting piece, the door plate 212 can be switched to the open state to facilitate the product in the inner cavity.
[0054] In the above embodiment, the connecting assembly 40 can be a magic tape. Specifically, the first connecting member 41 can be arranged on the top and bottom of the door plate 212, and the second connecting member 42 can be arranged on the top and bottom of the outer cover 22. When the door plate 212 is switched to the closed state, the second connecting member 42 can be pressed to be connected with the first connecting member 41, so that the door body is kept in the closed state. The above operation is simple and convenient.
[0055] In order to quickly realize that the door plate 212 can be rotated to open or close, in some embodiments, at least one thermal insulation plate 211 constitutes the door plate 212, and another thermal insulation plate 211 adjacent to the door plate 212 constitutes the side plate 213.
[0056] Part of the first connecting member 41 of one set of connecting assemblies 40 is arranged on the door plate 212, and the remaining part extends out of the door plate 212. The second connecting member 42 of the set of connecting assemblies 40 is arranged on the side plate 213. The part of the first connecting member 41 extending out of the door plate 212 can be detachably connected with the second connecting member 42. The first connecting member 41 can be bent and deformed to enable the door plate 212 to be rotated to the open state or the closed state relative to the side plate 213.
[0057] The number of door plates 212 can be one or multiple. In some embodiments, the number of door plates 212 is two, and the two door plates 212 are of a double-door structure. Each door plate 212 corresponds to a side plate 213 and can be rotated about the corresponding side plate 213. It can be understood that the first connecting member 41 is arranged on each of the two door plates 212 of the double-door structure, and the second connecting member 42 is arranged on the outer cover 22 and can cooperate with the first connecting member 41 on the two door plates 212. In this way, the second connecting member 42 can constrain the relative rotation of the two door plates 212.
[0058] It can be understood that the detachable connection mode of the multiple thermal insulation plates 211 is not limited, for example, a clamping structure can be arranged on the edge of the thermal insulation plate 211, or a connecting assembly 40 such as a magic tape can be arranged between adjacent thermal insulation plates 211.
[0059] In some embodiments, the thermal insulation container includes at least one set of connecting assemblies 40, each connecting assembly 40 including a first connecting member 41 and a second connecting member 42. One of the thermal insulation plates 211 constitutes the door plate 212, and the first connecting member 41 is arranged on each of the remaining thermal insulation plates 211. The second connecting member 42 is arranged on the outer cover 22, and the first connecting member 41 on each of the remaining thermal insulation plates 211 can be connected with the corresponding second connecting member 42 to connect the thermal insulation plate 211 with the outer cover 22. In this way, the reliability of the connection between the thermal insulation plate 211 and the outer cover 22 is improved, and the separation of the thermal insulation plate 211 in a transportation and vibration environment is avoided.
[0060] It can be understood that the outer cover 22 has an opening, and the inner core 21 can enter the outer cover 22 through the opening, and the door body is opposite to the opening to be exposed. In some embodiments, the first connecting piece 41 of one set of connecting assemblies 40 is arranged on the inner wall of the outer cover 22 close to the opening, and the second connecting piece 42 of the set of connecting assemblies 40 is arranged on the inner core 21, wherein the first connecting piece 41 and the second connecting piece 42 can be connected to each other to enable the inner core 21 and the outer cover 22 to be detachably connected.
[0061] In order to keep the inner cavity at a low temperature. In some embodiments, the inner cavity has a top surface, a bottom surface, and a plurality of side surfaces arranged between the top surface and the bottom surface, wherein the surface of each heat preservation plate 211 facing the inner cavity is provided with a plurality of pockets 2111 for placing ice packs. The ice pack is also an ice bag. The ice bag is placed in the pocket 2111, so that the inner cavity is kept at a low temperature. It can be understood that the heat preservation plate 211 forming the bottom surface does not have a pocket 2111 because it needs to bear the product. The remaining heat preservation plates 211 can be provided with pockets 2111.
[0062] The pocket 2111 can be selected as a mesh pocket to save materials and reduce costs. The opening of each pocket 2111 can be provided with a magic tape to seal the opening after the ice pack is placed, so as to avoid the ice pack from falling out of the pocket 2111 during transportation.
[0063] It can be understood that the specific structure of the heat preservation plate 211 is not limited and can meet the heat preservation requirement. In some embodiments, the heat preservation plate 211 includes two outer protective layers 2112, a polyurethane foam layer 2113 arranged between the two outer protective layers 2112, a filling heat preservation layer 2114 filled between the two polyurethane foam layers 2113, and an inner protective layer 2115 arranged between at least one inner side of the outer protective layer 2112 and the adjacent polyurethane foam layer 2113.
[0064] The outer protective layer 2112 is used to protect the internal heat preservation material and has relatively high strength. The polyurethane foam layer 2113 has a better heat preservation effect and relatively light gravity, thereby reducing the weight of the heat preservation plate 211. The filling heat preservation layer 2114 can be selected as a vacuum heat insulation plate, which has an excellent heat preservation and insulation effect.
[0065] The inner side refers to the side close to the inner cavity, so that the inner protective layer 2115 can reduce the possibility of the product colliding with the polyurethane foam layer 2113 during transportation. The inner protective layer 2115 can be a plastic sheet layer, which has high toughness and strength and can disperse the collision force to a larger area to improve the protection effect of the polyurethane foam layer 2113.
[0066] It can be understood that the specific structure of the outer support frame 10 and the connecting piece is not limited.
[0067] Please refer to Figure 1 and Figure 2 In some embodiments, the outer support frame 10 comprises a metal outer frame 11 and a metal inner net 12 arranged on the metal outer frame 11. The connecting members are straps, and a plurality of straps are arranged and fixed to the thermal inner core 20. The straps can be tied on the metal outer frame 11 and / or the metal inner net 12, thereby realizing detachable connection of the outer support frame 10 and the thermal inner core 20.
[0068] In the outer support frame 10, the metal outer frame 11 and the metal inner net 12 have relatively low manufacturing cost and relatively light weight. The straps can be connected by tying and separated by untie. Specifically, the outer support frame 10 composed of the metal outer frame 11 and the metal inner net 12 has a plurality of hollow holes, which can facilitate the tying of the straps. The straps can be tied on the metal outer frame 11, the metal inner net 12, or both.
[0069] In order to facilitate the movement of the thermal container, in some embodiments, the outer support frame 10 is provided with walking wheels at the bottom.
[0070] It should be noted that Figure 1 and Figure 2 In the outer support frame 10, the metal outer frame 11 and the metal inner net 12 have relatively low manufacturing cost and relatively light weight. The straps can be connected by tying and separated by untie. Specifically, the outer support frame 10 composed of the metal outer frame 11 and the metal inner net 12 has a plurality of hollow holes, which can facilitate the tying of the straps. The straps can be tied on the metal outer frame 11, the metal inner net 12, or both.
[0071] The embodiments of the present application also provide a thermal inner core 20 which can be applied to the thermal container of the above-mentioned embodiments.
