Description

Technical Field

[0001] This application relates to the technical field of cold chain transportation, and particularly to an insulated box. Background Art

[0002] With the rapid development of e-commerce, the generation volume of waste express packaging has also increased sharply. Therefore, the state has formulated relevant policies to limit excessive express packaging and advocated green packaging, so as to contribute to carbon emission reduction.

[0003] Currently, in the related art, recyclable packaging materials are generally used for cold chain transportation.

[0004] However, in cold chain transportation, especially in the scenario of food cold chain transportation, the packaging materials used in the related art are restricted by factors such as heat preservation performance, cleaning, and the number of recycling times, resulting in relatively high operation and maintenance costs, which is not conducive to popularization and application. Utility Model Content

[0005] Based on this, in view of the problem that the operation and maintenance costs of the packaging materials used in the related art are relatively high and not conducive to popularization and application, it is necessary to provide an insulated box.

[0006] An insulated box, the insulated box includes:

[0007] A box body, the box body has a heat preservation cavity and an opening, and has a first side surface and a second side surface facing away from each other;

[0008] A box cover, the box cover is used to cover the box body and close the opening;

[0009] At least 2 straps and the same number of fixing mechanisms, the fixing mechanisms are arranged on the second side surface, the straps include a belt body, a fixing part and a matching part, the fixing part is fixedly connected to the first side surface, and the matching part is used to be fixedly connected to the fixing mechanism so that the belt body fits and tightens on the box cover, and the box cover is pressed against the box body;

[0010] A pasting part, the pasting part is arranged at a preset position on the box cover or the box body, and the pasting part includes a groove and an anti-sticking pattern, the anti-sticking pattern is arranged on the surface of the groove, and the groove is used for the waybill to be pasted in alignment and makes the waybill cover the anti-sticking pattern.

[0011] The lid of this application is directly placed on the box body, which can reduce structural settings such as the rotation of the lid relative to the box body, helping to control the manufacturing cost of the insulation box. On this basis, the belt body is used to tighten the lid, ensuring that the lid can be firmly and stably placed on the box body, thus meeting the insulation performance requirements of the insulation box. Further, by fixing the lid with a strap, the fixing structure can be simplified while meeting the insulation performance, further controlling the manufacturing cost of the insulation box.

[0012] In addition, through the setting of the pasting part in this application, it prevents users from randomly pasting waybills on the box body or the lid, reducing the cleaning and maintenance cost of the recycled use of the insulation box. It should be noted that on traditional insulation boxes, if the waybill is directly pasted on the surface of the box body or the lid, the waybill is prone to warping due to friction during transportation, and even falls off due to friction. However, through the setting of the groove in this application, it helps to embed the waybill into the groove, making the surface of the waybill flush with the surface of the box body or the lid outside the groove, thus preventing the risk of the waybill falling off due to its own thickness. Furthermore, anti-sticking patterns are provided at the groove position, which can improve the simplicity of tearing off the waybill, reduce the probability of waybill residues sticking to the box body or the lid, and further reduce the cleaning and maintenance cost of the recycled use of the insulation box, which is beneficial to promotion and application.

[0013] In one embodiment, the matching part includes a fixed buckle with an opening. The fixing mechanism includes a fixed belt, a first buckle, and a second buckle. The first buckle and the second buckle are respectively arranged at both ends of the fixed belt. One end of the fixed belt is fixedly connected to the second side surface, and the other end of the fixed belt is used to pass through the opening and tighten the belt body. The first buckle and the second buckle are used to buckle with each other to realize the tightening effect of the belt body, so that the lid can be firmly and stably placed on the box body.

[0014] In one embodiment, the box body has a bottom opposite to the opening. The first side surface has a first height in the height direction relative to the bottom. The end of the fixed belt fixedly connected to the second side surface is connected to a position on the second side surface that is 1 / 2 of the first height away from the bottom, which can set the fixed belt at a reasonable height, ensuring sufficient operating space for the fixed belt and improving the simplicity of the operation when the fixed belt tightens the belt body.

[0015] In one embodiment, the fixing part is connected to a position on the first side surface that is 1 / 3 of the first height away from the bottom, which can ensure that the belt body has sufficient length and apply a more balanced and reliable tightening force to the lid.

[0016] In one embodiment, the incubator further includes a seal. When the first buckle is buckled with the second buckle, the seal is used to wind and tie the first buckle and the second buckle, so as to improve the buckling stability of the first buckle and the second buckle.

[0017] In one embodiment, the number of the second buckles is at least two, and the second buckles are distributed at one end of the fixing belt at intervals along the length direction of the fixing belt. The first buckle is used to selectively buckle with the second buckle, so as to overcome the stretching fatigue problem of the belt body, maintain the tightening force of the belt body, and further maintain the pressing force on the box cover.

[0018] In one embodiment, the groove is rectangular and has a central axis. The anti-sticking pattern includes a first stripe and a second stripe. The first stripe and the second stripe are parallel to each other and symmetrically arranged with respect to the central axis, so as to improve the simplicity of the operation of tearing the waybill, reduce the probability of the waybill being damaged during tearing and then causing residues, and further help reduce the cleaning and operation and maintenance costs of the subsequent recycling use of the incubator.

[0019] In one embodiment, a first gap is left between the side of the first stripe facing away from the second stripe and the edge of the groove, and a second gap is left between the side of the second stripe facing away from the first stripe and the edge of the groove. The settings of the first gap and the second gap can improve the adhesion between the edge of the waybill and the box body or the box cover, and then prevent the warping phenomenon of the waybill, and further improve the pasting stability of the waybill.

[0020] In one embodiment, the box body and the box cover are made of foamed polypropylene material, so as to balance the heat preservation performance and cost control of the incubator.

[0021] In one embodiment, the density range of the box body is 30 kg / m 3 -40 kg / m 3 ; the wall thickness range is 18 mm - 22 mm, so that the density and wall thickness of the box body can be set within a reasonable range to meet the heat preservation performance requirements of the incubator.

[0032] Refer to Figure 1 , Figure 1The structural schematic diagram of an incubator in an embodiment of the present application is shown. The incubator provided in an embodiment of the present application includes a box body 100, a box cover 200, at least two straps 300 and the same number of fixing mechanisms 400, and an adhesive part 500. The box body 100 has a heat preservation cavity and an opening 330a, and has a first side surface and a second side surface 100a facing away from each other. The box cover 200 is used to cover the box body 100 and close the opening 330a. The fixing mechanism 400 is arranged on the second side surface 100a. The strap 300 includes a strap body 310, a fixing part 320 and a matching part 330. The fixing part 320 is fixedly connected to the first side surface, and the matching part 330 is used to be fixedly connected to the fixing mechanism 400 so that the strap body 310 fits and tightens on the box cover 200, and the box cover 200 is pressed against the box body 100. The adhesive part 500 is arranged at a preset position on the box cover 200 or the box body 100, and the adhesive part 500 includes a groove 510 and an anti-adhesive pattern 520. The anti-adhesive pattern 520 is arranged on the surface of the groove 510. The groove 510 is used for the waybill to be aligned and pasted, and the waybill covers the anti-adhesive pattern 520.

[0033] When the above-mentioned incubator is in use, first place the consignment in the heat preservation cavity, then cover the box cover 200 on the box body 100 to seal the opening 330a of the box body 100, then pull out the strap body 310 from the first side surface respectively, and fix the matching part 330 and the fixing mechanism 400. In this way, the box cover 200 is firmly and stably covered on the box body 100 under the tightening action of the strap body 310. Finally, align the waybill with the groove 510 of the adhesive part 500 and paste it.

[0034] Specifically, the box cover 200 of the present application is directly covered on the box body 100, so as to reduce the structural settings such as the rotation of the box cover 200 relative to the box body 100, which helps to control the manufacturing cost of the incubator. On this basis, the box cover 200 is tightened by the strap body 310, so as to ensure that the box cover 200 can be firmly and stably covered on the box body 100, thereby meeting the heat preservation performance requirements of the incubator; further, by using the form of the strap 300 to fix the box cover 200, on the basis of meeting the heat preservation performance, the fixing structure can be simplified, and further the manufacturing cost of the incubator can be controlled.

[0035] In addition, with the provision of the pasting portion 500 in this application, it prevents users from randomly pasting waybills on the box body 100 or the box cover 200, reducing the cleaning, operation, and maintenance costs of the reusable insulated box. It should be noted that on traditional insulated boxes, if the waybill is directly pasted on the surface of the box body 100 or the box cover 200, the waybill is prone to warping due to friction during transportation and may even be rubbed off. However, with the provision of the groove 510 in this application, it helps to embed the waybill into the groove 510, making the surface of the waybill flush with the surface of the box body 100 or the box cover 200 outside the groove 510, thereby preventing the risk of the waybill being rubbed off due to its own thickness. Further, anti-sticking lines 520 are provided at the position of the groove 510, which can improve the simplicity of tearing the waybill and reduce the probability of waybill residues sticking to the box body 100 or the box cover 200, and further reduce the cleaning, operation, and maintenance costs of the reusable insulated box.

[0036] Therefore, the insulated box provided by this application can greatly simplify the structure, effectively reduce the manufacturing and operation, and maintenance costs of the insulated box on the basis of ensuring the insulation performance. Thus, in cold chain transportation, especially in the scenario of food cold chain transportation, it can effectively achieve a balance between the operation, and maintenance costs of the insulated box and the premium of the consignment, which is beneficial to promotion and application.

[0037] Optionally, as shown in Figure 2 Figure 8, the groove 510 is rectangular and has a central axis L. The anti-sticking lines 520 include a first stripe 521 and a second stripe 522. The first stripe 521 and the second stripe 522 are parallel to each other and symmetrically arranged with respect to the central axis L.

[0038] Specifically, in this embodiment, within the range where the groove 510 is formed, except for the areas where the first stripe 521 and the second stripe 522 are provided, enough smooth parts are reserved to ensure the adhesion between the waybill and the box body 100 or the box cover 200, thereby preventing the waybill from falling off. The first stripe 521 and the second stripe 522 are used to reduce the adhesion between the waybill and the box body 100 or the box cover 200, thereby improving the simplicity of the waybill tearing operation and reducing the probability of the waybill being damaged during tearing and causing residues, which further helps to reduce the cleaning, operation, and maintenance costs of the subsequent reusable insulated box.

[0039] Preferably, a first gap 521a is left between the side of the first stripe 521 facing away from the second stripe 522 and the edge of the groove 510, and a second gap 522a is left between the side of the second stripe 522 facing away from the first stripe 521 and the edge of the groove 510. The settings of the first gap 521a and the second gap 522a can improve the adhesion between the edge of the waybill and the box body 100 or the box cover 200, thereby preventing the warping of the waybill and improving the sticking stability of the waybill.

[0040] Optionally, referring back toFigure 1 , the engaging portion 330 can be, but is not limited to, implemented as including a fixed buckle. Preferably, the fixed buckle can be, but is not limited to, implemented as a double-layer D-shaped buckle. The fixed buckle has an opening 330a. The fixing mechanism 400 includes a fixing belt 410, a first buckle 420, and a second buckle 430. The first buckle 420 and the second buckle 430 are respectively arranged at both ends of the fixing belt 410. One end of the fixing belt 410 is fixedly connected to the second side surface 100a. The other end of the fixing belt 410 is used to pass through the opening 330a and tighten the belt body 310. The first buckle 420 and the second buckle 430 are used to engage with each other, thus realizing the tightening effect of the belt body 310 and enabling the box cover 200 to firmly and stably cover the box body 100.

[0041] Preferably, the fixing mechanism 400 further includes a magic tape 440. The magic tape 440 is arranged on the fixing belt 410 to improve the fitting degree of the fixing belt 410 when the first buckle 420 and the second buckle 430 engage with each other. On the one hand, this can prevent the first buckle 420 and the second buckle 430 from loosening. On the other hand, it can maintain the tightening force of the fixing belt 410 on the belt body 310.

[0042] Optionally, the incubator can be, but is not limited to, further including a seal 600. When the first buckle 420 engages with the second buckle 430, the seal 600 is used to wind and tie around the first buckle 420 and the second buckle 430, thus being able to improve the engagement stability between the first buckle 420 and the second buckle.

[0043] It should be noted that referring to Figure 1 , Figure 1 shows a schematic structural diagram of an incubator with 2 straps 300 and corresponding numbers of fixing mechanisms 400 in an embodiment. Understandably, one of the straps 300 is a schematic structural diagram where the first buckle 420 and the second buckle 430 do not engage with each other. Therefore, the schematic structural diagram of the seal 600 winding and tying around the first buckle 420 and the second buckle 430 is not shown here.

[0044] Optionally, the box body 100 has a bottom 100b opposite to the opening 330a. The first side surface has a first height relative to the bottom 100b in the height direction. One end of the fixing belt 410 fixedly connected to the second side surface 100a can be, but is not limited to, implemented as being connected to a position on the second side surface 100a at a distance of 1 / 2 of the first height h from the bottom 100b. In this way, the fixing belt 410 can be set at a reasonable height, thereby ensuring that the fixing belt 410 has sufficient operating space and improving the operational simplicity when the fixing belt 410 tightens the belt body 310.

[0045] Specifically, in this embodiment, when the fixing strap 410 needs to pass through the opening 330a, the operation can be carried out at a height above 1 / 2 of the first height h, which provides better operational simplicity and avoids the problem of insufficient tightening force on the strap body 310 caused by insufficient tightening space.

[0046] Preferably, the fixing part 320 is connected to a position on the first side surface at a distance of 1 / 3 of the first height from the bottom, so as to ensure that the strap body 310 has sufficient length, and then apply a more balanced and reliable tightening force to the lid 200.

[0047] Optionally, in some embodiments, the number of the second latches 430 is at least two, and the second latches 430 are spaced along the length direction of the fixing strap 410 at one end of the fixing strap 410, and the first latch 420 is used to selectively engage with the second latches 430.

[0048] Specifically, under the condition that the strap body 310 has been used for a certain period of time, a certain tensile fatigue phenomenon will occur. Then, by arranging the second latches 430 spaced along the length direction of the fixing strap 410 at one end of the fixing strap 410, the first latch 420 can selectively engage with the second latches 430, so as to overcome the tensile fatigue problem of the strap body 310, maintain the tightening force of the strap body 310, and then maintain the pressing force on the lid 200.

[0049] Preferably, the box body 100 and the lid 200 are made of foamed polypropylene material, so as to take into account both the heat preservation performance of the insulation box and cost control.

[0050] Specifically, among the packaging materials currently used in cold chain transportation, the main heat insulation materials are XPS (Extruded Polystyrene Board), PU+VIP (Polyurethane foam+ Vacuum Insulation Panel), and EPP (Expanded Polypropylene), etc. Among them, XPS or PU+VIP heat insulation materials are generally used in higher-end pharmaceutical cold chain scenarios due to their high prices. In the food cold chain scenario, because the premium of the consignment is not high, using EPP heat insulation materials can effectively control costs and meet the requirements of heat preservation performance.

[0051] Preferably, the density range of the box body 100 is 30 kg / m3 - 40 kg / m3, and the wall thickness range is 18 mm - 22 mm. In this way, the density and wall thickness of the box body 100 can be set within a reasonable range to meet the heat preservation performance requirements of the incubator. Specifically, the inventor finally determined the density range of the box body 100 to be 30 kg / m3 - 40 kg / m3 and the wall thickness range to be 18 mm - 22 mm according to the actual scenario requirements and financial calculations. The specific density and wall thickness can be adjusted according to the actual design requirements to maximize the benefits.

[0052] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0053] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
