Even during bumpy conditions, the lid and base are unlikely to separate, and gaps are less likely to form. This improves the sealing performance between the lid and base, ensuring the box remains at a consistently low temperature and providing better insulation, thus solving the problem of poor sealing performance.

Description

Technical Field

[0001] This utility model relates to the field of cold chain transportation, and in particular to a refrigerated insulated box. Background Technology

[0002] The instant retail industry is developing rapidly. For fresh and frozen foods that require temperature control, goods are quickly picked and packaged in cold storage and delivered to consumers within a certain time frame. Throughout the transportation process, the goods are kept in a suitable temperature environment to ensure product quality.

[0003] Traditional insulated boxes for storing fresh and frozen foods are bulky and lack handles, making them extremely inconvenient to move and stack. To achieve the required insulation performance, these boxes consume large amounts of refrigerant (such as ice plates or dry ice), resulting in high material costs. Furthermore, these boxes are difficult to clean and have a strong odor. They also have a high breakage rate and their lifespan does not meet requirements. From a logistics perspective, existing insulated boxes are non-standard sizes, meaning their loading capacity is not maximized whether placed on standard pallets or loaded onto trucks.

[0004] The existing patent authorization announcement number CN207917631U discloses an insulated box, in which the outer surface of the box body 1 is provided with a strap 3, which can be in the form of a handle or a shoulder strap, and the handle and shoulder strap forms can be converted between each other. This allows the transporter to choose different forms according to different situations, reducing physical exertion, and the conversion between the two forms is simple and quick.

[0005] The box body 1 and the box cover 2 that close the box body 1 are designed so that the box cover 2 can close onto the box body 1. However, the box cover 2 is easy to separate from the box body 1, especially during transportation. Due to factors such as bumps, the box cover 2 may not be able to seal the box body 1, resulting in poor insulation of the box. Although there is a strap 3, the strap 3 is mainly used for carrying by hand or on the back, and the strap 3 does not have a fixing effect on the box cover 2.

[0006] During the aforementioned transportation process, it was discovered that the sealing performance of the insulated boxes needed improvement. Utility Model Content

[0007] The purpose of this invention is to provide a refrigerated insulated box that solves the problem of poor sealing performance of insulated boxes.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] This utility model provides a refrigerated insulated box, including a box body, a heat insulation layer, and an ice plate.

[0010] The box includes a bottom box and a lid. The bottom box has an inner cavity, and the lid is used to cover the opening end of the inner cavity. A constraint strap is wrapped around the outer surface of the box to bind the bottom box and the lid together.

[0011] The heat insulation layer and the ice plate are disposed in the inner cavity, which is also used to accommodate items that need to be refrigerated, and a protective layer is disposed on the surface of the heat insulation layer.

[0012] Optionally, the insulation layer is a VIP panel, which can be integrally formed or composed of multiple pieces spliced ​​together.

[0013] Optionally, the box body is provided with a groove, the groove extends on the bottom box and the box cover, and the restraining strap is located in the groove.

[0014] Furthermore, it also includes a pull ring, with the first end of the restraint strap fixed to the pull ring, and the second end of the restraint strap having a Velcro fastener with a male and a female fastener. The Velcro fastener passes through the pull ring and then folds back to engage the male and female fasteners together.

[0015] Furthermore, an annular groove is provided on the outer wall of the bottom box, and an annular belt is provided inside the annular groove.

[0016] Optionally, the enclosure is provided with a mounting slot, and a temperature recorder is installed in the mounting slot. The temperature recorder has a temperature probe that extends into the inner cavity, and the temperature recorder is used to monitor the temperature inside the enclosure.

[0017] Optionally, the protective layer is a PP board, and the protective layer is attached to the heat insulation layer.

[0018] Optionally, the protective layer is a plastic-sealed shell with a receiving cavity for accommodating the heat insulation layer, and an ice groove for accommodating the ice plate.

[0019] Optionally, a lower protective shell is provided at the bottom of the base box, and an upper protective shell is provided on the box cover.

[0020] Optionally, it also includes a latch, the cover of which is provided with a slot, the latch including a base, a lever, a first shaft, a second shaft and a hook, the base being disposed on the bottom box, the first shaft being disposed on the base, the lever being rotatably disposed on the first shaft, the second shaft being disposed on the lever, and the hook being rotatably disposed on the second shaft, the hook being able to engage with and disengage from the slot.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] This utility model discloses a refrigerated insulated box. Because the bottom box has an insulation layer and an ice plate, the ice plate is used to cool down, and the insulation layer prevents heat exchange, keeping the bottom box at a low temperature. The restraint straps fix the lid and the bottom box together, so even when bumpy, the lid and the bottom box are not easy to separate, and there are no gaps between the lid and the bottom box. The sealing performance between the lid and the bottom box is improved. In this way, the insulated box is kept at a low temperature, and the insulation effect of the insulated box is better. Therefore, the problem of poor sealing effect of the insulated box is solved. Attached Figure Description

[0036] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] Example 1

[0038] like Figure 1 and Figure 2 and Figure 3 As shown, a refrigerated insulated box includes a box body 1, an insulation layer 2, and an ice plate 3. The insulation layer 2 and the ice plate 3 are both disposed inside the box body 1. The box body 1 includes a bottom box 11 and a lid 12. The bottom box 11 has an inner cavity 13. The lid 12 is used to cover the opening end of the inner cavity 13. The inner cavity 13 is also used to hold items that need to be refrigerated. When refrigerated products need to be put in or taken out, the lid 12 needs to be opened. When there are refrigerated products in the inner cavity 13, the lid 12 is used to cover the opening end of the inner cavity 13, that is, the lid 12 covers the bottom box 11. The lid 12 has a sealing effect on the inner cavity 13.

[0039] Box 1 is made of EPP beads through foaming. EPP (Expanded Polypropylene) is the Chinese term for foamed polypropylene.

[0040] The surface of the insulation layer 2 is provided with a protective layer 21. The insulation layer 2 is a vacuum VIP panel. The VIP panel is lightweight. The insulation layer 2 is easily punctured by frozen products. After puncture, condensation water seeps into the VIP panel, affecting the heat preservation performance. In order to prevent the insulation layer 2 from cracking, the protective layer 21 protects the insulation layer 2. The insulation layer 2 can be integrally molded or multiple pieces spliced ​​together. In this example, the protective layer 21 is an injection molded shell.

[0041] In this way, when an odor appears inside the housing 1 and it is difficult to clean, the protective layer 21 can be removed directly and replaced with a new protective layer 21, which is a new injection-molded shell. As needed, the protective layer 21 and the heat insulation layer 2 can be replaced at the same time.

[0042] The insulation layer 2 is generally set on the bottom box 11. The insulation layer 2 can also be set on the box cover 12 by means of adhesive or non-adhesion, usually by adhesive.

[0043] The protective layer 21 is an injection-molded shell with a cavity 22 for accommodating the heat insulation layer 2. The heat insulation layer 2 is not easily shaken in the cavity 22.

[0044] The protective layer 21 can also form a cavity 22 between itself and the housing 1, instead of forming a cavity 22 inside the protective layer 21. The housing protects the outer side of the VIP panel, and the plastic shell protects the inner side of the VIP panel.

[0045] The outer surface of the box 1 is wrapped with restraint straps 4, which are used to restrain the bottom box 11 and the box cover 12.

[0046] Together, the lid 12 is hinged to the upper end of the bottom box 11. The lid 12 is hinged to the bottom box 11 by a hinge to prevent the lid and the bottom box from separating. When the lid 12 is on the opening end of the inner cavity 13, the bottom box 11 and the lid 12 are restrained together by the restraint strap 4. In this way, even if the insulated box is bumped, the lid 12 cannot flip on the bottom box 11. The restraint strap 4 helps the lid 12 to seal the inner cavity 13, that is, the lid 12 has better sealing performance for the inner cavity 13.

[0047] The housing 1 is provided with a groove 14, which extends from the bottom box 11 and the cover 12. The restraint band 4 is located in the groove 14, and the groove 14 can restrict the slippage of the restraint band 4. The number of restraint bands 4 and grooves 14 can be set as needed.

[0048] The insulated box also includes a pull ring 5. The first end of the restraint strap 4 is fixed to the pull ring 5. The second end of the restraint strap 4 has a Velcro 41 with a male and a female buckle. The Velcro 41 passes through the pull ring 5 and then folds back, so that the male and female buckles are engaged. The male and female buckles can be connected or unengaged. When the box lid 12 is to be opened, the male and female buckles must be unengaged. When the box lid 12 is placed on the bottom box 11, the restraint strap 4 is tightened and the male and female buckles are engaged.

[0049] An annular groove 15 is provided on the outer wall of the base box 11, and an annular belt 6 is provided inside the annular groove 15. The annular belt 6 has a restraining effect on the base box 11, preventing the base box 11 from expanding or bulging outward, while the annular groove 15 prevents the annular belt 6 from slipping.

[0050] The insulation box also includes a collar 7, a ring belt 6 and a restraint belt 4 that intersect through the collar 7, and a ring groove 15 that communicates with a belt groove 14.

[0051] The bottom box 11 is provided with pull grooves 27 on both sides. The two pull grooves 27 facilitate manual handling. The bottom box 11 is also provided with a flip groove 28. The flip groove 28 and the hinge are located on the side of the bottom box 11. The flip groove 28 facilitates manual flipping of the box cover 12.

[0052] like Figure 4 and Figure 5 As shown, the housing 1 is provided with a mounting slot 16, and a temperature recorder 8 is installed in the mounting slot 16. The temperature recorder 8 has a temperature probe. The housing 1 has a hole through which the temperature probe extends into the inner cavity 13. The temperature probe monitors the temperature inside the housing 1. The temperature measured by the temperature probe is stored by the temperature recorder 8. The temperature recorder 8 can store temperature data for up to 72 hours. The temperature recorder 8 performs data acquisition.

[0053] The bottom of the base box 11 is provided with a lower protective shell 17, and the top cover 12 is provided with an upper protective shell 18. The lower protective shell 17 extends into the annular groove 15 and the band groove 14, and the upper protective shell 18 extends into the band groove 14. The lower protective shell 17 and the upper protective shell 18 are made of PP material (Polypropylene). The restraint band 4 has a fixing effect on the lower protective shell 17 and the upper protective shell 18, and the annular band 6 has a fixing effect on the lower protective shell 17.

[0054] It also includes a latch 9, and the lid 12 is provided with a slot 19. The latch 9 includes a base 91, a lever 92, a first shaft 93, a second shaft 94, and a hook 95. The base 91 is set on the bottom box 11, the first shaft 93 is set on the base 91, the lever 92 is rotatably set on the first shaft 93, and when the lever 92 is pulled manually, the lever 92 can rotate on the first shaft 93. The second shaft 94 is set on the lever 92, and the hook 95 is rotatably set on the second shaft 94. When the lever 92 rotates, the hook 95 rotates on the second shaft 94, and the hook 95 can engage with or move away from the slot 19, so that the lid 12 is tightly closed on the bottom box 11. When the lever 92 rotates, the hook 95 can engage in the slot 19, or the hook 95 can move away from the slot 19, and the hook 95 is separated from the slot 19. In this way, the lid 12 can be flipped on the bottom box 11. A lock can also be set to prevent the lever 92 from being operated.

[0055] Lock 9 can be fitted with UHF RFID anti-theft cable ties.

[0056] like Figure 1 and Figure 6 As shown, the upper surface of the box cover 12 is provided with an upper positioning strip 10, and multiple upper positioning strips 10 are provided. The lower surface of the bottom box 11 is provided with multiple lower grooves 20. The upper positioning strips 10 and the lower grooves 20 correspond one-to-one. When multiple boxes 1 are to be stacked together, the lower groove 20 of the upper box 1 is used to fit onto the upper positioning strip 10 of the lower box 1. In this way, the multiple boxes 1 stacked together are more stable and less likely to tip over.

[0057] The standardized dimensions of container 1 allow for easy stacking on transport vehicles or refrigerated trucks, maximizing loading capacity, and multiple containers 1 stacked together will not tilt.

[0058] like Figure 2 and Figure 7 As shown, the protective layer 21 has a first fixing strip 25 and a second fixing strip 26. An ice trough 23 is formed between the first fixing strip 25, the second fixing strip 26 and the inner wall of the protective layer 21. The ice trough 23 is used to accommodate the ice plate 3. The ice plate 3 usually includes a shell (not shown in the figure). The shell contains a cooling medium such as ice. When there are products to be delivered in the box 11, the ice plate 3 is placed in the ice trough 23. The ice plate 3 is not easy to shake in the ice trough 23. The ice plate 3 is placed reasonably, which makes the space layout inside the box 1 reasonable.

[0059] The combination of VIP panels and EPP enclosure has good thermal insulation properties. Therefore, after meeting the thermal insulation requirements of enclosure 1, the VIP and EPP can be relatively thin after molding, making enclosure 1 lighter and maximizing its volume ratio. The amount of ice plate 3 inside enclosure 1 is small, which can meet the thermal insulation performance requirements in all aspects.

[0060] Example 2

[0061] Unlike Example 1, the protective layer 21 can be adhered to the surface of the heat insulation layer 2 and the VIP panel surface.

[0062] The purpose of laminating a layer of plastic sheet about 1mm thick (the material can be PP, PS, PET, etc.) is to protect the VIP board. The lamination method mainly involves using double-sided tape to bond the sheet to one side of the VIP board, and protecting the sides with tape. PS is polystyrene (abbreviated PS), and PET is polyethylene terephthalate, a common thermoplastic polyester material.

[0063] The protective layer 21 can be attached to both sides of the VIP panel or to the inside. When attached to the inside, the outer side of the VIP panel is protected by the enclosure.

[0064] Example 3

[0065] like Figure 8 As shown, the protective layer 21 includes an injection-molded shell and a plastic sheet, which means that the plastic sheet is pasted on the surface of the heat insulation layer 2, and the heat insulation layer 2 with the plastic sheet pasted on is fitted into the injection-molded shell.

[0066] When the protective layer 21 is a plastic sheet pasted on the surface of the heat insulation layer 2, the heat insulation layer 2 together with the protective layer 21 form a frame. The sleeve 31 is used to surround the upper part of the frame to protect the top surface of the heat insulation layer 2.

[0067] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
