However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0039] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0040] like Figures 1 to 3 As shown, this disclosure provides a fresh produce crate 1, which includes a frame body 2 and a base pad 3. The frame body 2 may include a base plate 21 and side plates 22 arranged around the base plate 21. The base plate 21 and the side plates 22 form a receiving groove with a top opening. The base pad 3 is disposed within the receiving groove and connected to the base plate 21.

[0041] In this embodiment of the disclosure, the bottom pad 3 may include at least an antibacterial layer 31, which can cover the bottom of the receiving tank. The antibacterial layer 31 is made of hemp fiber composite material, which has the characteristics of antibacterial properties, high specific strength and specific modulus, non-brittle fracture, renewability and degradability.

[0042] In some embodiments, the raw materials for hemp fiber composite materials may include hemp fibers and polypropylene (i.e., PP).

[0043] It should be noted that the polypropylene used in this embodiment is a material with good processing properties and mechanical strength. Hemp fiber is a widely available renewable resource in nature.

[0044] For example, hemp fiber can be bast fibers represented by ramie, flax, hemp, jute, and kenaf, as well as leaf fibers represented by sisal. These fibers originate from the stems, roots, leaves, or seeds of plants, so we can obtain them sustainably without depleting the Earth's resources. Furthermore, hemp fiber is biodegradable, meaning it decomposes naturally after disposal, leaving no lasting pollution in the environment. Therefore, hemp fiber is a renewable and biodegradable environmentally friendly resource. Additionally, hemp fiber has advantages such as antibacterial properties, high length, high specific strength, and high specific modulus.

[0045] This embodiment of the disclosure uses hemp fiber and polypropylene to make the antibacterial layer 31. In other words, this embodiment uses a hemp fiber composite material containing hemp fiber and polypropylene to make the antibacterial layer 31. Therefore, the base pad 3 can possess properties such as antibacterial activity, high specific strength and specific modulus, environmental friendliness, and non-brittle fracture. The preparation of the hemp fiber composite material using hemp fiber and polypropylene can be achieved using relevant technologies. This application does not improve the hemp fiber composite material or its preparation method, and will not elaborate on it here.

[0046] Specifically, in this embodiment, the antibacterial layer 31 is made of hemp fiber composite material. The high specific strength and specific modulus of hemp fiber can be used to reduce the weight of the base mat 3 and improve the convenience of transportation. At the same time, it can also improve the structural rigidity of the base mat 3 and reduce the deformation of the base mat 3 when subjected to external forces, thereby improving the load-bearing capacity of the base mat 3 and increasing the durability of the base mat 3, thereby reducing the cost of repairing or replacing the base mat 3 in the fresh food crate 1.

[0047] This embodiment of the invention utilizes the antibacterial properties of hemp fiber to extend the shelf life of fresh produce such as fruits and vegetables and reduce the risk of spoilage during transportation and storage when the base pad 3 is used in the fresh food cold chain packaging industry.

[0048] This embodiment utilizes the non-brittle fracture property of hemp fiber to enhance the energy absorption of the base pad 3, improve its impact resistance, and reduce the possibility of damage to fresh produce transported within the fresh produce crate 1. Furthermore, this embodiment utilizes the renewable and biodegradable properties of hemp fiber to meet the green transformation needs of the fresh produce cold chain packaging industry.

[0049] In some embodiments, hemp fiber composite materials may also be made by fusing hemp fibers with other matrix resins besides polypropylene, such as traditional resins derived from petroleum, such as epoxy resin (ER), or biodegradable bio-based polymers such as polyhydroxyalkanoates (PHAs), aliphatic polyesters such as poly(β-hydroxybutyrate) (PHB), copolymers of 3-hydroxybutyric acid and 3-hydroxyvalerate (PHBV), polylactic acid (PLA), or polymers synthesized from biomass such as itaconic acid and rosin-based resins, to form a lightweight material with low density, high strength, low carbon footprint, and recyclability.

[0050] In some embodiments, the thickness of the antibacterial layer 31 can be in the range of 0.5mm-2mm.

[0051] For example, the thickness of the antibacterial layer 31 can be 0.5mm, 1mm, 1.5mm, 2mm, etc., but it is not limited to these. The thickness of the antibacterial layer 31 can also be other values ​​other than 0.5mm-2mm. The specific value can be set according to the size of the frame 2, so as to ensure the load-bearing performance and antibacterial effect of the antibacterial layer 31, while avoiding problems such as the container volume being too small, the fresh food frame 1 being too heavy, and the manufacturing cost of the antibacterial layer 31 being too high due to the antibacterial layer 31 being too thick.

[0052] like Figures 2 to 3 As shown, in some embodiments, the base pad 3 may further include a support layer 32, which is disposed on the side of the antibacterial layer 31 near the base plate 21. The top surface of the support layer 32 is connected to the bottom surface of the antibacterial layer 31, and the bottom surface of the support layer 32 is connected to the top surface of the base plate 21. By providing the support layer 32, the overall structural strength of the base pad 3 can be strengthened, thereby improving the load-bearing capacity and rigidity of the base pad 3, reducing the risk of damage to the base pad 3, and extending the service life of the base pad 3.

[0053] In this embodiment, the support layer 32 may be made of hemp fiber composite material, but is not limited thereto. The support layer 32 may also be made of other materials with good hardness besides hemp fiber composite material, and the specific material may be selected according to the actual situation.

[0054] In some embodiments, at least a part of the outer peripheral surface of the support layer 32 abuts against the inner side surface of the side peripheral plate 22, so as to increase the contact surface between the support layer 32 and the antibacterial layer 31, and reduce the occurrence of deformation such as curling at the part of the side periphery of the antibacterial layer 31 that is not in contact with the support layer 32, thereby reducing the risk of damage to the antibacterial layer 31 and extending its service life.

[0055] Specifically, the support layer 32 in the embodiments of the present disclosure may be a solid layer covering the bottom of the accommodating groove, so as to increase the contact surface between the support layer 32 and the side peripheral plate 22, strengthen the stability of the connection between the support layer 32 and the side peripheral plate 22, and improve the support performance of the support layer 32 against the antibacterial layer 31.

[0056] However, it is not limited thereto. In the embodiments of the present disclosure, the support layer 32 may be a hollowed-out layer covering the bottom of the accommodating groove.

[0057] Exemplarily, the support layer 32 in the embodiments of the present disclosure may include a plurality of through holes arranged at intervals in an array. The through holes penetrate through the support layer 32, so as to reduce the mass of the support layer 32, that is, reduce the overall mass of the bottom pad 3, thereby reducing the transportation cost.

[0058] As Figure 3 shown, in some embodiments, the through holes in the support layer 32 can be made into the bionic hexagonal shape of a honeycomb. However, it is not limited thereto. The through holes in the embodiments of the present disclosure can also be in shapes such as "square", "double-square", "X" shape, etc. other than hexagons, so as to effectively ensure the structural strength of the support layer 32 while saving the manufacturing materials of the support layer 32.

[0059] For example, the through holes on the support layer 32 can be regular hexagons, and the distance between one through hole and any adjacent through hole is set at equal intervals, so as to improve the stability of the support performance of the support layer 32 against the antibacterial layer 31.

[0060] In the embodiments of the present disclosure, the value range of the distance between two adjacent through holes can be: 0.06 mm - 0.12 mm.

[0061] For example, the value of the distance between two adjacent through holes can be: 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.11 mm, 0.12 mm, etc., so as to minimize the weight of the support layer 32 while ensuring the overall structural strength of the support layer 32.

[0062] In the embodiments of the present disclosure, the value range of the thickness of the support layer 32 can be: 1 mm - 4 mm.

[0063] For example, the thickness of the support layer 32 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc., so as to reduce the volume occupied by the support layer 32 on the receiving groove while ensuring the overall structural strength of the support layer 32, thereby increasing the capacity of the fresh food frame 1.

[0064] In this embodiment of the disclosure, the bottom pad 3 and the bottom plate 21 can be connected and fixed by welding, bonding or other methods.

[0065] Specifically, the bottom surface of the support layer 32 near the bottom plate 21 can be welded or bonded to the top surface of the bottom plate 21 to achieve the connection between the bottom pad 3 and the bottom plate 21.

[0066] In addition, when the base pad 3 has both a support layer 32 and an antibacterial layer 31, the support layer 32 and the antibacterial layer 31 can also be connected by welding or bonding.

[0067] like Figure 2 As shown, in some embodiments, the side plate 22 may include a perforated portion 221 and a reinforcing portion 223. Both the perforated portion 221 and the reinforcing portion 223 are arranged around the base plate 21, with the perforated portion 221 located on the side of the reinforcing portion 223 closest to the base plate 21. The bottom surface of the perforated portion 221, facing away from the reinforcing portion 223, is connected to the base plate 21, and the top surface of the perforated portion 221, facing away from the base plate 21, is connected to the bottom surface of the reinforcing portion 223.

[0068] The perforated section 221 has multiple arrayed perforations 222 to enhance the air permeability of the fresh produce frame 1, reducing the accumulation of moisture and humidity inside the frame, which could lead to problems such as dampness and spoilage of fresh produce. Simultaneously, by providing multiple perforations 222 on the perforated section 221, the overall weight of the frame 2 can be reduced, thereby lowering transportation and manufacturing costs.

[0069] Correspondingly, the reinforcing part 223 can be a solid structure without the perforated holes 222. For example, in the embodiments of this disclosure, the reinforcing part 223 can be a solid sheet material arranged around the base plate 21 to enhance the overall structural strength of the side plate 22.

[0070] It should be noted that, as Figure 1 As shown, when the frame 2 is a prism, the portion of the hollow part 221 located at each corner can be set as a solid structure. That is, the present disclosure may not set hollow holes 222 in the portion of the hollow part 221 located at each corner, so as to strengthen the structural strength of the corresponding area of ​​each corner of the frame 2 and reduce the risk of damage when the frame 2 collides with other structures.

[0071] In this embodiment, the base plate 21 can extend horizontally, and the side plate 22 can extend vertically, with the horizontal direction perpendicular to the vertical direction. However, it is not limited to this; the side plate 22 can also form a certain angle with the vertical direction.

[0072] like Figure 1 As shown, in some embodiments, the side plate 22 may include multiple side plates, each of which is provided with a carrying hole 224 for easy handling.

[0073] The center of the handle hole 224 in the horizontal direction can coincide with the center of the corresponding side plate in the horizontal direction. In the vertical direction, the handle hole 224 can be located in the upper middle part of the corresponding side plate.

[0074] For example, the frame 2 in this embodiment can be a rectangle. In this case, the side plate 22 includes four side plates, two of which can be located on opposite sides of the base plate 21 in the transverse X direction, and the other two side plates can be located on opposite sides of the base plate 21 in the longitudinal Y direction. On the two side plates extending in the transverse X direction, the central axis of the handle hole 224 in the transverse X direction coincides with the central axis of the corresponding side plate in the transverse X direction. On the two side plates extending in the longitudinal Y direction, the central axis of the handle hole 224 in the longitudinal Y direction coincides with the central axis of the corresponding side plate in the longitudinal Y direction. However, this is not a limitation. The frame 2 in this disclosure can also be other shapes besides a rectangle, depending on the actual situation.

[0075] It should be noted that in this disclosure, both the horizontal X and vertical Y directions are horizontal, and the horizontal X and vertical Y directions are perpendicular to each other.

[0076] like Figure 1 As shown, in some embodiments, the frame 2 may include a plurality of first reinforcing members 23 arranged in an array at intervals, the first reinforcing members 23 extending in a vertical direction and connected to the outer side surface of the side plate 22.

[0077] For example, when the frame 2 is a rectangular body, multiple first reinforcing members 23 can be provided on each side plate of the side peripheral plate 22 to enhance the overall structural strength of the frame 2.

[0078] like Figure 1 As shown, in some embodiments, the frame 2 may include a second reinforcing member 24 arranged around the side plate 22, the second reinforcing member 24 being connected to the outer surface of the side plate 22 to enhance the overall structural strength of the frame 2.

[0079] For example, when the side plate 22 includes a hollow portion 221 and a reinforcing portion 223, a second reinforcing member 24 may be provided at the boundary line between the hollow portion 221 and the reinforcing portion 223. However, it is not limited to this, and the second reinforcing member 24 may also be provided at other locations besides the boundary line between the hollow portion 221 and the reinforcing portion 223 in the embodiments of this disclosure.

[0080] For example, when the frame 2 is provided with a first reinforcing member 23, a second reinforcing member 24 and a handle hole 224, the first reinforcing member 23 and the second reinforcing member 24 can be arranged around the side of the handle hole 224.

[0081] like Figure 2 and Figure 4 As shown, in some embodiments, a limiting member 25 may be provided on the base plate 21. The top surface of the limiting member 25 is connected to the bottom surface of the base plate 21. The limiting member 25 extends vertically away from the receiving groove, that is, the limiting member 25 is located outside the receiving groove and protrudes downward from the bottom surface of the base plate 21. The limiting member 25 is provided around the inner side surface of the side plate 22, and the orthographic projection of the limiting member 25 on the base plate 21 is located within the orthographic projection of the receiving groove on the base plate 21.

[0082] When two fresh food crates 1 overlap vertically, the bottom surface of the bottom plate 21 in the upper fresh food crate 1 abuts against the top surface of the side plate 22 in the lower fresh food crate 1. The limiting member 25 in the upper fresh food crate 1 can be embedded into the receiving groove of the lower fresh food crate 1. In this embodiment of the present disclosure, the limiting member 25 can be used to limit the distance between the upper and lower fresh food crates 1, thereby reducing the instability when the fresh food crates 1 are stacked.

[0083] For example, the height of the limiting member 25 in this embodiment of the present disclosure can be in the range of 3mm-15mm.

[0084] For example, the height of the limiting member 25 can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc., but is not limited to these. The specific height of the limiting member 25 can be adjusted according to the volume of the frame 2.

[0085] like Figure 2 As shown, in some embodiments, a carrier plate 26 may be disposed on the top surface of the side plate 22 away from the bottom plate 21. The carrier plate 26 is disposed around the outer periphery of the side plate 22, and the inner periphery of the carrier plate 26 is flush with the inner periphery of the side plate 22, while the outer periphery of the carrier plate 26 protrudes outward from the outer periphery of the side plate 22. In the embodiments of this disclosure, the carrier plate 26 can avoid occupying space in the receiving slot while increasing the contact surface between the two stacked fresh food frames 1.

[0086] Specifically, when two fresh food crates 1 are stacked one on top of the other, the top surface of the carrier plate 26 of the lower fresh food crate 1, which is away from the bottom plate 21, can be completely abutted against the bottom surface of the bottom plate 21 of the upper fresh food crate 1. The area of ​​the top surface of the carrier plate 26 is larger than the area of ​​the top surface of the corresponding side plate 22. Compared with the solution where the top surface of the side plate 22 directly abuts against the bottom surface of the other fresh food crate 1, the present embodiment can increase the contact surface between the two stacked fresh food crates 1 by setting the carrier plate 26, thereby reducing the contact stress between the two fresh food crates 1 and improving the stability of the stacking of the two fresh food crates 1.
