Description

Technical Field

[0001] This utility model relates to the field of logistics packaging, and in particular to a fresh produce packaging box. Background Technology

[0002] With the rise of online shopping, more and more goods can be purchased online, including fresh products such as meat, eggs, dairy products, and cooked food. Typically, fresh goods like meat and seafood require insulated boxes and ice packs for transportation to prevent spoilage.

[0003] However, existing packaging technologies have certain drawbacks. Firstly, the seal between the foam box and the lid is not tight, relying entirely on adhesive tape for sealing. This makes the seal prone to breakage or leaks during transport, causing ice packs to melt quickly and the goods to spoil. Secondly, existing fresh produce packaging makes it impossible to visually assess the internal low-temperature environment, lacking a basis for replenishing ice packs. In hot weather or long-distance transport, slow delivery or delayed pickup can lead to ice pack melting, often resulting in disputes between consumers and delivery personnel due to spoiled goods. Currently, there are no corresponding solutions to these problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fresh food packaging box with a simple structure, stronger sealing performance, and the ability to observe the internal temperature environment without damaging the packaging.

[0005] The equipment includes a housing and a lid. A protruding sealing ring and a recessed sealing groove are respectively provided on the top of the housing and the inner surface of the lid. The sealing ring and sealing groove are correspondingly provided.

[0006] The effect achieved is that the tight fit between the sealing groove and the sealing ring improves the airtightness of the sealed box and prevents it from communicating with the outside air.

[0007] The box body or box cover is integrated with a temperature-sensitive color-changing area.

[0008] The effect achieved is that the temperature-sensitive color-changing area senses the internal temperature of the box and changes in real time accordingly. In other words, the real-time temperature inside the insulated box can be observed through the temperature-sensitive color-changing area, serving as a basis for determining whether the inside of the insulated box is still in a low-temperature environment during delivery and receiving handover.

[0009] The beneficial effects of this utility model are: it solves the problem in the prior art that the internal temperature of the packaging box cannot be directly observed from the outside. It uses temperature-sensitive color-changing materials to reflect the internal temperature in real time at extremely low cost, allowing for timely replenishment of ice packs to prevent food spoilage; it also serves as important evidence for determining the cause of spoilage and for refusing acceptance of goods. Furthermore, the equipment has better sealing performance. Attached Figure Description

[0016] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0017] Reference Figure 1 , Figure 2 The present invention provides a fresh produce packaging box, comprising a box body 1 and a box lid 2. A protruding sealing ring 12 and a recessed sealing groove 22 are respectively provided on the top surface of the box body 1 and the inner surface of the box lid 2. The sealing ring 12 and the sealing groove are correspondingly provided.

[0018] The effect achieved is that the tight fit between the sealing groove and the sealing ring 12 improves the airtightness of the sealing box and prevents it from communicating with the outside air.

[0019] The box body 1 or the box cover 2 is integrated with a temperature-sensitive color-changing area 3.

[0020] The effect achieved is that the temperature-sensitive color-changing zone 3 senses the internal temperature of the chamber 1 and changes in real time with the internal temperature. In other words, the real-time temperature inside the insulation chamber can be observed through the temperature-sensitive color-changing zone 3 to determine whether refrigerant needs to be added.

[0021] It also serves as a criterion for determining whether the inside of the insulated box is still in a low-temperature environment during the delivery and receipt process.

[0022] In Example 1, the temperature-sensitive color-changing zone 3 is set in the following form:

[0023] An assembly slot is provided on the side wall of the housing 1. The two ends of the assembly slot are sealed by transparent partitions, and the assembly slot is vacuum-sealed.

[0024] Temperature-sensitive color-changing paper is affixed to the internal transparent partition. Here, "internal" refers to the end of the two transparent partitions closest to the inner cavity of the housing 1.

[0025] The goal is to achieve internal temperature observation at the lowest possible cost.

[0026] In Example 2, the temperature-sensitive color-changing zone 3 is set in the following form:

[0027] An assembly slot is provided on the side wall of the housing 1, and an observation window is fixedly provided on the outside of the assembly slot. The observation window is in the form of a transparent partition.

[0028] Inside the assembly channel, where "inside" refers to the direction closer to the inner cavity of the housing 1, a color-changing capsule is fixedly installed. The color-changing capsule is made of transparent material and is filled with temperature-sensitive color-changing powder.

[0029] The effect achieved in this way is that the color of the color-changing capsule can be directly observed through the observation window, which can be used to determine its internal temperature.

[0030] Furthermore, the observation window is equipped with a one-way air valve, and the assembly slot between the observation window and the color-changing capsule is vacuum-sealed.

[0031] The effect of this is to prevent heat exchange through the temperature-sensitive color-changing zone 3 during transportation, which could cause the internal ice packs to melt.

[0032] In Example 3, both the box body 1 and the box lid 2 are made of plastic foam.

[0033] The temperature-sensitive color-changing zone 3 is made by mixing temperature-sensitive color-changing material into the foam molding process of the box body 1 or the box cover 2.

[0034] The effect achieved in this way is that the color change of box 1 is more intuitive.

[0035] Example 4: The outside of the box body 1 or the box cover 2 is provided with a color and temperature comparison mark of the temperature-sensitive color-changing zone 3.

[0036] The effect achieved in this way is to intuitively determine the internal temperature of chamber 1.

[0037] Example 5, refer to the accompanying drawings in the specification. Figure 2 The box body 1 and the box cover 2 are separate parts;

[0038] An assembly boss 11, which is shorter than the box body 1, is integrally connected to the box body 1. The sealing ring 12 is integrally disposed outside the assembly boss 11, and its arrangement is a circumferential arrangement.

[0039] The inner surface of the box cover 2 is provided with a concave sealing groove 22 corresponding to the sealing ring 12.

[0040] Furthermore, the sealing ring 12 is a ring with a semi-circular cross-section, and its radius is larger than that of the sealing groove. Here, "larger than" means slightly larger.

[0041] The effect achieved is that the sealing ring 12 and the concave sealing groove 22 are interference-fitted, ensuring their internal sealing performance.

[0042] Furthermore, the side of the lid 2 or the body 1 is also provided with a recessed handle 21.

[0043] This makes it easier to move.
