Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a packaging bag with a moisture-proof structure after the bag is opened. Background Art

[0002] Sealing is the most fundamental and important function of any packaging. It can ensure that the items are effectively protected from moisture and isolated from the air. The literal meaning of the word "sealed" usually means that the packaging inside the packaging container cannot be exchanged with the outside world. In fact, there are very few absolutely sealed packages.

[0003] Existing sealed packaging bags usually do not have a protective structure at the self-sealing strip during use, which can easily cause the self-sealing strip to loosen and open when the packaging bag is squeezed, thereby affecting the sealing effect. In addition, due to the single structure, the moisture-proof effect is poor, which reduces the applicability of the packaging bag. Therefore, we propose a packaging bag with a moisture-proof structure after the bag is opened. Utility Model Content

[0025] Example

[0026] See also Figures 1-4 , a packaging bag with a moisture-proof structure after bag opening, comprising:

[0027] Packaging bag body 1;

[0028] Sealing mechanism 1, sealing mechanism 1 is arranged on the packaging bag body 1, sealing mechanism 1 includes a fixing plate 2, fixing plate 2 is fixedly connected to the packaging bag body 1, fixing plate 2 is rotatably connected to fixing plate 2, fixing plate 2 is provided with two sealing grooves 4, fixing plate 2 is fixedly connected to two sealing strips 5, sealing strips 5 are adapted to sealing groove 1 4, packaging bag body 1 is located between sealing strips 5 and sealing groove 1 4, fixing plate 1 is fixedly connected to two fixing shafts 6, both fixing shafts 6 are rotatably connected to limit plates 7, sealing strips 5 and sealing groove 1 4 are used to perform double-layer sealing on packaging bag body 1, and limit plates 7 are used to limit and fix fixing plate 2 3;

[0029] Sealing mechanism 2 is arranged on fixed plate 1 2 and fixed plate 2 3. Sealing mechanism 2 includes two grooves 2. Both grooves 2 are opened on fixed plate 1 2 and fixed plate 2 3. Sealing groove 2 8 and sealing block 9 are fixedly connected in the two grooves 2 respectively. Sealing groove 2 8 is adapted to sealing block 9 and is used to seal the opening of the packaging bag body 1 to further improve the sealing effect.

[0030] Two limiting grooves 10 are provided on the fixing plate 2 3 , and a fixing groove is provided on the limiting plate 7 , in which a rubber pad 11 is fixedly connected. The rubber pad 11 is located in the limiting groove 10 to prevent the limiting plate 7 from rotating without human power.
