[0039] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0040] Embodiment one
[0041] As shown in Figure 1 and Figure 2 , the embodiment is applicable to pre-prepared dishes with simple packaging, short shelf life, and only local or small-scale sales. Specifically, the embodiment discloses a packaging assembly facilitating the detection of the freshness of food materials, comprising a first packaging 100 and a gel detection label 200.
[0042] The first packaging 100 has a first containing space and a first visible part for at least partially displaying the first containing space. The gel detection label 200 is arranged in the first containing space and located within the visible range corresponding to the first visible part.
[0043] The first containing space is a sealed space, and one or more subspaces can be arranged according to the types of food materials. The subspaces can be connected or independent of each other. Obviously, in the case of multiple subspaces, each subspace contains food materials of a corresponding type, and the gel detection label 200 is arranged in the corresponding subspace according to the type of food materials to achieve the purpose of separate detection. It should be noted that if only one type of food material needs to be detected for freshness in the foregoing case, the subspace where the food material is located can be connected with other subspaces. However, if at least two types of food materials need to be detected for freshness, the corresponding subspaces are isolated and independent of other subspaces to prevent detection errors.
[0044] Embodiment two
[0045] As shown in Figures 3 to 8 , the embodiment is applicable to pre-prepared dishes with relatively complex packaging, relatively long shelf life, and cross-regional transportation needs. Specifically, the embodiment provides a packaging assembly facilitating the detection of the freshness of food materials, comprising a first packaging 100, a second packaging 400, and a gel detection label 200.
[0046] The first packaging 100 has a first containing space and a first visible part for at least partially displaying the first containing space.
[0047] The second package 400 is arranged in the first accommodating space, and has a second accommodating space and a second visible part for at least partially displaying the second accommodating space, the second accommodating space being a sealed space, and the second visible part being located in the visible range corresponding to the first visible part. Obviously, the first package 100 is an outer package, and the second package 400 is an inner package, so that the second package 400 can accommodate food materials in a vacuum mode, thereby improving the storage time and meeting the requirements of long-distance transportation of food materials.
[0048] The gel detection label 200 is arranged in the second accommodating space and located in the visible range corresponding to the second visible part.
[0049] Embodiment three
[0050] As shown in Figure 9 and Figure 10 The embodiment provides a packaging assembly facilitating detection of the freshness of food materials, which comprises:
[0051] The first package 100 has a first accommodating space and a first visible part for at least partially displaying the first accommodating space.
[0052] The second package 400 is arranged in the first accommodating space, and has a second accommodating space, a first communicating hole 401 communicating the second accommodating space, and a first easily-tearable part 402 arranged at the first communicating hole 401 in a separable manner, the first communicating hole 401 being located in the visible range corresponding to the first visible part.
[0053] The third package 500 has a third accommodating space, a second communicating hole 501 communicating the third accommodating space, and a second easily-tearable part 502 arranged at the second communicating hole 501 in a separable manner, the third package 500 being arranged at the first communicating hole 401 in a sealed manner, and the second communicating hole 501 being in communication with the first communicating hole 401.
[0054] The gel detection label 200 is arranged in the third accommodating space.
[0055] The embodiment has the advantages that the gel detection label 200 can be sealed in the production link, so that the accuracy of detection is not affected by early contact with sensitive sources. In the packaging and use links, the second accommodating space and the third accommodating space can be communicated by removing the first easily-tearable part 402 and the second easily-tearable part 502.
[0056] As a preferred example, the first easily-tearable part 402 is arranged at the first communicating hole 401 in a separable manner by means of cementing, and the second easily-tearable part 502 is arranged at the second communicating hole 501 in a separable manner by means of cementing.
[0057] Based on the packaging forms formed by the packaging assemblies in Embodiment One to Embodiment Three, the utility model patent further provides a structure of the first package 100. Specifically, as shown in Figures 1 to 6 The first package 100 can adopt a bowl-shaped or a plate-shaped structure, and the first package 100 comprises a main body part 102 and a cover part 101. The main body part 102 serves as a receiving function, and this part mainly embodies the overall shape of the first package 100.
[0058] The main body part 102 has an open part for taking and placing the contents, and the food materials are placed into or taken out of the first receiving space through the open part. The cover part 101 is detachably arranged at the open part to form the first receiving space, for example, by welding to seal and connect on site. The first visible part is formed on the cover part 101. Obviously, the materials of the main body part 102 and the cover part 101 are both food-grade waterproof materials, and the hardness of the former is greater than that of the latter, which is the prior art and will not be described in detail. The material of the main body part 102 is a non-transparent material, and the material of the cover part 101 is a transparent material. For the first visible part, it can be any suitable area in the completely visible area formed by maintaining the transparent properties of the material itself without any printing, or it can be a suitable visible area surrounded by a non-visible area formed by printing. It can be known that the area of the first visible part is greater than the area of the gel detection label 200.
[0059] Based on the packaging forms formed by the packaging assemblies in Embodiment Two and Embodiment Three, the utility model patent further provides another structure of the first package 100. Specifically, as shown in Figure 7 and Figure 8 The first package 100 adopts a box-shaped structure, and the first package 100 comprises a main body part 102 and a window part 103. The main body part 102 has an opening part arranged on the side surface to take and place the contents and a window part 104 arranged on the front surface to at least partially display the contents, and the window part 103 is arranged on the window part 104, and the first visible part is formed on the window part 103.
[0060] As a preferred example, since the gel detection label 200 reflects the freshness of the food materials through color change, in order for the user to better judge the freshness of the food materials, the packaging assemblies in Embodiment One to Embodiment Three further comprise a reference detection label 300, and the reference detection label 300 and the gel detection label 200 can be observed at the same time. Specifically, for Embodiment One, the reference detection label 300 is arranged in the first receiving space. For Embodiment Two and Embodiment Three, the reference detection label 300 is arranged in the first receiving space or the second receiving space.
[0061] The reference detection label 300 has two display modes. One display mode is set according to the color change of the gel detection label 200, that is, the reference detection label 300 is provided with multiple colors, which correspond to different preservation days of the food material. This display mode is suitable for users to directly observe the freshness of the food material by the naked eye, and the judgment result is different for different people, so there may be a large error. Another display mode is to set a reference color, and the freshness of the food material is determined by comparing the color development of the gel detection label 200 with the reference color, that is, the color difference formed by the two labels corresponds to different preservation days of the food material. This display mode is suitable for judging the freshness of the food material by visual recognition after scanning by the equipment, and the judgment result is determined by the machine, so the error is small. It should be noted that the specific judgment method of the latter can be realized according to the prior art, and details are omitted.
[0062] As a preferred example, the reference detection label 300 can be adhered to the corresponding visible part in the form of a physical label, or can be printed on the corresponding visible part.
[0063] As a preferred example, the packaging assembly in Embodiments 1 to 3 further comprises a waterproof and breathable film, which is arranged in the space where the gel detection label 200 is located to isolate the gel detection label 200 from the content. That is, the waterproof and breathable film can wrap the gel detection label 200 in a relatively sealed space, which can allow gas to enter but prevent liquid from entering. The purpose of arranging the waterproof and breathable film is to prevent the problem of color development inaccuracy caused by the contamination of the gel detection label 200 by the colored liquid such as blood water or seasoning carried or generated by the food material.
[0064] It should be noted that the gel detection label 200 in the present application is made of a gelatin-arabic gum aerogel, and the preparation method of the gelatin-arabic gum aerogel has been disclosed in the invention patent with the publication number CN118027500A and the name of a preparation method of a gelatin-arabic gum aerogel and its application. The gel detection label 200 can respond to the ammonia released into the surrounding environment by the food material during the preservation process to produce color change, thereby playing a role in detecting the freshness of the food material.
[0065] The details not described in the present application are known to those skilled in the art.
[0066] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified and replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
