Technical Field
[0001] The utility model relates to the technical field of packaging bags, and more specifically to a moisture-proof packaging bag. Background Art
[0002] Rice is a necessity in people's daily life. There are two types of rice sold in the market: one is bulk rice and the other is bagged rice. However, the packaging bags of bagged rice have a single shape and style, and neither has good moisture resistance. Consumers need to pour the bagged rice into a special rice barrel for storage after buying it. However, since the volume of many rice barrels does not match the volume of packaging bags on the market, many bagged rice cannot be poured into the rice barrel at one time, which brings a lot of inconvenience to people's lives.
[0003] In view of the above problems, regarding the technical problem of poor moisture-proofness of existing rice packaging bags, after a lot of searching, a rice moisture-proof packaging bag with patent number CN218506560U was found. The packaging bag body is provided with a handle clamp, a storage bag and a fixed base in sequence. The fixed base is bonded to the bottom of the storage bag, the fixed base is rectangular in shape, and the handle clamp is arranged on the top of the storage bag; the handle clamp is in the shape of a ring, and a handle is arranged inside the handle clamp; a sealing port is bonded to the side wall of the storage bag, a zipper is bonded to the top of the storage bag, and a placement groove is arranged inside the storage bag; the handle is made of plastic, and the handle provided on the handle clamp reduces the damage to the user's hands when carrying the bagged rice, and improves the user's comfort when carrying. The zipper is set, so that the rice inside the storage bag can be replenished when it is less, and it is convenient to use. The rice inside the storage bag flows out through the sealing port, and the amount of rice flowing out can be effectively controlled. The packaging bag body is placed upright by setting the fixed base. However, the technical solution provided by the patent has the following problems:
[0004] (1) The device is sealed by a zipper, but the zipper is difficult to seal, which causes water vapor to enter the packaging bag, causing the rice to become damp and moldy;
[0005] (2) The device achieves a moisture-proof effect by filling desiccant between the extruded film and the storage bag. However, a bag of rice is used for a long time, and the desiccant will reach its moisture adsorption limit after a short period of use. Especially in the southern region with high humidity, the effective time of the desiccant will be even shorter. The desiccant filled between the extruded film and the storage bag cannot be replaced with a new desiccant after it expires, and the device cannot be moisture-proof for a long time.
[0006] The utility model can play the role of sealing the packaging bag and facilitating the replacement of the desiccant. Utility Model Content

[0030] In the embodiment of the utility model, the sealing mechanism 5 includes: a bottom plate 501, a sealing strip 502, a sealing plate 503, a drawstring 504 and a connecting plate 505. The top of the storage bag 1 is connected to the bottom plate 501, the front end of the top of the bottom plate 501 is connected to the sealing strip 502, the rear end of the top of the bottom plate 501 is installed with the connecting plate 505, the front end of the connecting plate 505 is installed with the sealing plate 503, and the front end of the top of the sealing plate 503 is connected with the drawstring 504. Through the bottom plate 501, the effect of providing support for the sealing mechanism 5 is achieved; through the sealing strip 502 and the sealing plate 503, the effect of sealing the packaging bag is achieved; through the drawstring 504, the effect of facilitating opening of the sealing plate 503 is achieved; through the connecting plate 505, the effect of connecting the bottom plate 501 and the sealing plate 503 is achieved.
[0031] In the embodiment of the utility model, the sealing strip 502 is arrow-shaped, and a sealing groove that fits with the sealing strip 502 is opened at the bottom of the sealing plate 503 to achieve the effect of sealing the packaging bag. The sealing strip 502 is inserted into the sealing groove, and the arrow-shaped part of the sealing strip 502 can prevent the sealing strip 502 from moving out of the sealing groove, thereby ensuring the sealing of the packaging bag.
