Description

Technical Field

[0001] The utility model relates to the technical field of food packaging bags, and specifically relates to a packaging bag with a secondary sealing structure. Background Art

[0002] Food packaging bags are a type of packaging design. In daily life, in order to facilitate the preservation and storage of food, product packaging bags have emerged. Food packaging bags refer to thin film containers that are in direct contact with food and are used to hold and protect food. At the same time, food packaging bags should be produced using food-grade plastic films.

[0003] However, there are still certain deficiencies in the use of existing food packaging bags. For example, the existing food packaging bags use self-sealing strips for sealing. It is easy for dust or small foreign objects to fall into the gap above the self-sealing strip. After the self-sealing strip is opened, dust or small foreign objects are likely to fall into the packaging bag. Moreover, it is not convenient to perform secondary sealing on the food packaging bag, and only the self-sealing strip is used for sealing, resulting in insufficient sealing performance. Therefore, we propose a packaging bag with a secondary sealing structure. Summary of the Utility Model

[0024] Embodiment

[0025] Please refer to Figures 1-5 , a packaging bag with a secondary sealing structure, comprising:

[0026] Bag body 1;

[0027] Sealing mechanism, the sealing mechanism is arranged on the bag body 1, and the sealing mechanism includes a self-sealing strip 2, a fixed plate 3, a first fixing block 4 and a second fixing block 5. The self-sealing strip 2 is fixedly connected inside the bag body 1, the fixed plate 3, the first fixing block 4 and the second fixing block 5 are all fixedly connected to the bag body 1, the first fixing block 4 and the second fixing block 5 are both fixedly connected to the fixed plate 3, the first fixing block 4 is fixedly connected with an adjusting block 6, the adjusting block 6 is rotatably connected with a pressing plate 7, two sliding grooves are opened on the pressing plate 7, a slide block 8 is slidably connected in the sliding groove, a spring 9 is arranged between the slide block 8 and the sliding groove, the slide block 8 is fixedly connected with a connecting block 10, the connecting block 10 penetrates through the sliding groove through a control port, a control block 11 is fixedly connected to the two connecting blocks 10, a limiting groove is opened on the second fixing block 5, one ends of the two slide blocks 8 are both located in the limiting groove, a baffle 12 is fixedly connected to the fixed plate 3, the spring 9 is used to push against the slide block 8, the slide block 8 and the limiting groove are used for limiting, and the self-sealing strip 2, the fixed plate 3, the pressing plate 7, the slide block 8, etc. are used to perform two seals on the bag body 1, avoiding the entry of dust and the like.

[0028] Preferably, a protective sleeve 13 is fixedly connected to the bag body 1, and a shaping strip 14 is arranged inside the protective sleeve 13 for propping up the bag opening of the bag body 1 to facilitate people to use the bag body 1.

[0029] A rubber strip 15 is fixedly connected to the pressing plate 7 for further cooperating with the pressing plate 7 and the fixing plate 3 to squeeze and seal the bag body 1.

[0030] Anti-slip lines 16 are provided on the control block 11 to increase the friction and facilitate people's control.
