Description

Technical Field

[0001] This utility model relates to a food packaging bag, specifically a food packaging bag with a desiccant fixed in place. Background Technology

[0002] Traditional food packaging bags typically contain desiccants placed directly inside the bag or fixedly adhered to the inner wall. Once the desiccant becomes ineffective, it cannot be easily replaced. Users are forced to discard the entire bag, resulting in resource waste, increased costs, and a violation of environmental protection principles.

[0003] Existing packaging bags rely on material deformation or adhesive sealing. After long-term use, the seals are prone to failure due to material aging, external pressure, or repeated opening and closing, allowing moisture to seep in and causing food to become damp and spoil. Especially for foods in high-humidity environments or those requiring long-term storage, the moisture-proof performance of ordinary sealing methods is limited. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a food packaging bag with a desiccant fixed in place, so as to solve the problems existing in the background art.

[0005] The food packaging bag with a desiccant fixed in this utility model is achieved through the following technical solution, including a packaging bag body and a sealing structure set on the packaging bag body;

[0006] The main body of the packaging bag is equipped with a desiccant placement structure. By opening the desiccant placement structure, the desiccant can be placed inside, thereby keeping the food inside the main body of the packaging bag dry.

[0007] As a preferred technical solution, the desiccant placement structure includes a mounting plate and a screw cap;

[0008] The mounting piece is fixed to the inner side of the main body of the packaging bag, and a connecting seat is provided at the front end of the mounting piece, and the connecting seat passes through the main body of the packaging bag.

[0009] The outer side of the connecting seat is provided with an external thread, and the inner side of the screw cap is provided with an internal thread, and the screw cap is connected by the external thread and the internal thread; a desiccant placement position is formed on the connecting seat, and the desiccant is placed in the desiccant placement position;

[0010] The desiccant placement area is provided with a vent hole, and the vent hole is connected to the inside of the packaging bag body, thereby achieving the drying of the food inside the packaging bag.

[0011] As a preferred technical solution, the sealing structure includes a front cover plate and a rear cover plate;

[0012] The front cover plate is provided with a first connecting protrusion, and the first connecting protrusion is connected to the first connecting piece at the front end of the opening of the main body of the packaging bag; the rear cover plate is provided with a second connecting protrusion, and the second connecting protrusion is connected to the second connecting piece at the rear end of the main body of the packaging bag.

[0013] The front cover plate has two protrusions on its lower side, and the rear cover plate has two grooves, with the protrusions and grooves corresponding to each other. When the front cover plate and the rear cover plate are fixed by a locking structure, the protrusions are placed in the grooves, thereby achieving a seal on the main body of the packaging bag.

[0014] As a preferred technical solution, the locking structure includes a locking screw disposed on the front cover plate and a locking hole disposed on the rear cover plate;

[0015] When the main body of the packaging bag is in a sealed state, the locking end of the locking screw is placed in the locking hole, thereby achieving a seal on the main body of the packaging bag.

[0016] The beneficial effects of this utility model are:

[0017] This invention features an independent, openable desiccant placement structure, allowing users to easily open the cap, remove expired desiccant, and add new desiccant. This enables the packaging bag itself to be reused, eliminating the need to discard the entire bag due to desiccant expiration, thus reducing costs and being more environmentally friendly.

[0018] This utility model uses the protrusion of the front cover plate to cooperate with the groove of the rear cover plate and is locked by the locking screw to ensure that the protrusion and the groove are tightly fitted to form a physical sealing barrier. Attached Figure Description
