[0002] Oxygen absorbers are one of the most common active packaging materials on the market. They can absorb oxygen in food packaging containers to inhibit the growth of aerobic bacteria and prevent the oxidation of oils and fats, thereby achieving the purpose of preservation and extending the shelf life. If you want to visually see whether the deoxidizer has completely achieved the deoxygenation effect, you can make a judgment through the different display colors of the oxygen indicator.

[0003] Common oxygen indicators are red in the absence of oxygen and blue in the presence of oxygen. The integrated oxygen indicator deoxidizer on the market fixes the oxygen indicator line on the surface of the packaging bag or the side seal, and sets a transparent or translucent window on the indicator part. Since the oxygen indicator line is continuous, the two ends of the indicator line are directly exposed when the deoxidizer is cut into single packages for use, and the indicator solution contained in the indicator line will be exposed to the outside world. When used in food packaging, the indicator solution may diffuse due to factors such as humidity and oil, thereby affecting food safety. Utility Model Content

[0020] Any process or method description in the flowchart or otherwise described herein may be understood to represent a module, fragment or portion of code that includes one or more executable instructions for implementing the steps of a specific logical function or process, and the scope of the preferred embodiments of the present invention includes alternative implementations in which functions may not be performed in the order shown or discussed, including performing functions in a substantially simultaneous manner or in the reverse order depending on the functions involved, which should be understood by technicians in the technical field to which the embodiments of the present invention belong.

[0021] like Figures 1 to 3 As shown, the utility model provides a closed oxygen indicator 2 deoxidizer, comprising a deoxidizer portion 1, an oxygen indicator 2 and a pasting portion for pasting the oxygen indicator 2 on the deoxidizer portion 1, the pasting portion is provided with a surface film body 3 and an intermediate film body 4, the outer side of the intermediate film body 4 is provided with a first adhesive layer 5, and the inner side is provided with a second adhesive layer 6, the intermediate film body 4 is adhered to the surface of the deoxidizer portion 1 through the second adhesive layer 6, the oxygen indicator 2 is pasted on the first adhesive layer 5, the surface film body 3 covers the oxygen indicator 2 and is adhered to the outer surface of the intermediate film body 4 through the first adhesive layer 5.

[0022] A transparent observation window 7 is provided in the middle of the surface film body 3. On the one hand, the oxygen indicator 2 is pasted through the adhesive part, and the oxygen indicator 2 is sealed and covered by the surface film body 3 and pasted on the surface of the adhesive part. On the other hand, the adhesive part is adhered to the surface of the deoxidizer to form a whole with the deoxidizer, so that the deoxidizer has the function of the oxygen indicator 2. At the same time, the oxygen indicator 2 is covered by the surface film body 3, so that the oxygen indicator 2 can be isolated from the outside, and the internal oxygen indicator 2 solvent liquid diffusion caused by the direct exposure of the oxygen indicator 2 to the outside is avoided, thereby affecting food safety. At the same time, the color indication state of the oxygen indicator 2 can be directly observed through the observation window 7, and the deoxidation effect of the deoxidizer can be quickly understood.

[0023] At the same time, during the manufacturing process, a layer of separation bottom film can be first pasted on the inner side of the intermediate film body 4, and the pasting portion can be completed by die-cutting. After the die-cutting of the pasting portion is completed, when it needs to be pasted to the outer surface of the deoxidizer portion 1, the separation bottom film is torn off to expose the second adhesive layer 6, which can be directly pasted to the outer periphery of the deoxidizer portion 1, which is convenient and quick to use.

[0024] On the outer side of the intermediate film body 4, a serrated groove 8 is provided at the periphery of the oxygen indicator 2, and the surface film body 3 is adhered to the top of the groove 8; the outer periphery of the intermediate film body 4 is provided with a step 9 whose height is lower than the height of the outer side surface of the intermediate film body 4; the middle part of the surface film body 3 is adhered to the outer side of the intermediate film body 4, and its peripheral part is adhered to the surface of the step 9.

[0025] The surface film body 3 is attached to the outer side of the middle film body 4, and the step 9 is lower than the height of the outer side of the middle film body 4, so that the surface film body 3 can be naturally bent when attached, which can form a buckling effect, and can ensure that the surface film body 3 and the middle film body 4 can be more tightly bonded together on the outer side of the middle film body 4. When the corners of the surface film body 3 are pried, it will firstly only affect the bonding part of the step 9 part, and will not affect the middle part, so that the surface film body 3 and the middle film body 4 can be reliably bonded in the middle part, and the oxygen indicator 2 can be reliably isolated.

[0026] At the same time, the serrated grooves 8 can produce some hollow isolation areas. On the one hand, it can prevent the surface film body 3 and the intermediate film body 4 from being separated from each other due to the surface film body 3 being pried, and the resulting area spreading to the middle. At the same time, the hollow isolation area can have a certain sealing effect, thereby increasing the sealing performance of the oxygen indicator 2 inside it. At the same time, the serrated grooves 8 have a greater positive pressure, which can increase the glue bonding pressure between the surface film body 3 and the intermediate film body 4, and enhance the bonding force between the surface film body 3 and the intermediate film body 4.

[0027] The material of the intermediate film body 4 is a breathable material, and the material of the intermediate film body 4 is paper, non-woven fabric or breathable film. The intermediate film body 4 is made of a breathable material to ensure that the oxygen indicator 2 can accurately measure and display the deoxygenation state. At the same time, the intermediate film body 4 is between the oxygen indicator 2 and the deoxidizer part 1, avoiding direct contact between the oxygen indicator 2 and the deoxidizer part 1, and solving the defects such as the color development performance of the oxygen indicator 2 being reduced or the color change time being slow due to the heat of the deoxidizer part 1 during production or use.

[0028] The oxygen indicator 2 is in the form of a sheet, in the shape of a 20 mm×20 mm square or a 20 mm diameter circle; the observation window 7 is in the shape of a 15 mm×15 mm square or a 15 mm diameter circle. The first adhesive layer 5 and the second adhesive layer 6 are made of food grade or plant-based glue, and the adhesion of the first adhesive layer 5 or the second adhesive layer 6 is ≥0.5 kgf / inch.

[0029] The deoxidizer of the above-mentioned size can ensure that the oxygen indicator 2 can quickly and accurately display deoxygenation, and it is convenient to observe the color change state of the oxygen indicator 2. At the same time, it can also ensure that the oxygen indicator 2 and the deoxidizer can be stably combined to form a whole. At the same time, the food grade or plant system used can avoid the deoxidizer from contaminating the food as a whole, thereby improving the safety of use.
