Description

Fresh packaging box Technical Field The utility model relates to the field of logistics packaging, in particular to a fresh packaging box. Background With the rise of online shopping, more and more commodities can be purchased in the form of online shopping, wherein the commodities comprise fresh products such as meat, egg, milk, cooked food and the like. Generally, fresh goods such as meat and water are transported by an insulation box and an ice bag in the transportation process, so as to avoid deterioration of goods. However, the packaging box in the prior art has certain disadvantages, on one hand, the sealing between the box body and the box cover of the packaging box made of foam materials is not tight, the sealing is completely realized by the glue packaging belt, the packaging damage or the packaging uncleanness and other conditions easily occur in the transportation process, the ice bag is quickly melted, the commodity is deteriorated, on the other hand, the fresh packaging in the prior art cannot observe whether the low-temperature environment in the fresh packaging is good from the outside, the basis for supplementing the ice bag is lacking, and the problems of hot weather, long transportation distance, such as slow logistics distribution, untimely goods taking and other special conditions, the ice bag is melted, and consumers or delivery personnel often have disputes due to the deterioration of the internal commodity. In view of the above problems, there is currently no corresponding solution. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide the fresh packaging box which has a simple structure and stronger sealing property, and particularly can observe the internal temperature environment in the period without damaging the packaging. The device comprises a box body and a box cover, wherein the upper surface of the box body and the inner surface of the box cover are respectively and correspondingly provided with an outwards protruding sealing ring and an inwards concave sealing groove. The sealing ring is arranged corresponding to the sealing groove; The sealing groove is tightly embedded with the sealing ring, so that the tightness of the sealing box is improved, and the sealing box is prevented from being communicated with the outside air; And a temperature-sensitive color-changing area is integrally arranged on the box body or the box cover. The effect achieved by the method is that the temperature sensing color-changing area senses the temperature in the box body and changes along with the temperature in the box body in real time. That is, the real-time temperature inside the incubator can be observed through the temperature-sensitive color-changing area, and the temperature-sensitive color-changing area is used for judging whether the inside of the incubator is still in a low-temperature environment or not in the process of dispatching and receiving delivery. The utility model solves the problem that the internal temperature of the packing box cannot be directly observed from outside in the prior art, reflects the internal temperature of the packing box in real time by using the temperature-sensitive color-changing material, supplements the ice bag in time, avoids food deterioration, and is also used as important evidence for judging and rejecting the deterioration reason of goods. Meanwhile, the sealing performance of the device is better. Drawings FIG. 1 is a schematic view of a fresh packaging box according to the present utility model; FIG. 2 is a schematic diagram of an assembly structure of a fresh packing box according to the present utility model; FIG. 3 is a cross-sectional view based on FIG. 2; Reference numerals: 1-case body 2-case cover 3-temperature sensing color-changing area 11-Assembling boss 12-sealing ring 21-handle 22-concave sealing groove The achievement of the objects, functional features and advantages of the present utility model will be further described with reference to the accompanying drawings, in conjunction with the embodiments. Detailed Description Referring to fig. 1 and 2, the fresh packaging box of the present utility model includes a box body 1 and a box cover 2, and an outwardly protruding sealing ring 12 and an inwardly concave sealing groove 22 are respectively provided on the upper surface of the box body 1 and the inner surface of the box cover 2. The sealing ring 12 is arranged corresponding to the sealing groove; The effect achieved by this is that the tightness of the seal box is improved by the tight jogging of the seal groove and the seal ring 12, and the communication with the outside air is avoided; The box body 1 or the box cover 2 is integrally provided with a temperature-sensitive color change area 3. The effect achieved by this is that the temperature-sensitive color-changing area 3 senses the internal temperature of the box body 1 and changes in real time with the internal temperature.
