They have the significant advantages of being biodegradable, renewable and environmentally friendly, and meet the demand for environmentally friendly packaging in modern society. They also have certain strength and flexibility, and can better carry and protect items. The packaging paper bag closing mechanism is a structure used to close and seal the bag openings of various packaging paper bags. Its core purpose is to ensure that the items contained in the paper bag can be properly sealed during use to prevent the items from accidentally spilling from the bag opening and being contaminated by the outside world.

[0003] With the continuous development of global environmental protection concepts, the importance of environmental protection concepts has become increasingly high. People are paying more and more attention to the environmental properties of packaging materials. Paper packaging bags have become a trend.

[0032] Please see the attached Figure 1 , Attachment Figure 2 and attached Figure 4 The top of the outer wall of the packaging bag 1 is provided with a closing piece 3, and the top of the outer wall of the closing piece 3 is provided with a closing groove 4. The packaging bag 1 is used to hold the required items. The top of the outer wall of the closing piece 3 is designed and provided with a closing groove 4. The setting of the closing groove 4 makes the packaging bag 1 more convenient to seal during use, thereby effectively protecting the safety and freshness of the items in the bag.

[0033] Please see the attached Figure 1 and attached Figure 3 The partitioning mechanism 2 includes a foam board 201. The bottom of the foam board 201 is fixedly connected to the bottom of the inner wall of the packaging bag 1. A cross groove 202 is provided on the top of the foam board 201. The bottom of the foam board 201 is tightly connected to the bottom of the inner wall of the packaging bag 1 by bonding and sewing to ensure its firmness. The top of the foam board 201 is designed with a cross-shaped notch. The setting of the cross groove 202 further enhances the stability of the foam board 201 and makes it easy to place items between the notches, thereby achieving effective partitioning of the internal space of the packaging bag 1. To better protect the items in the package and prevent them from collision and displacement during transportation, and to ensure the safety of the items, the inner wall of the cross groove 202 is installed with a partition plate 1 203, and the outer wall of the partition plate 1 203 is provided with a splicing groove 204, and the inner wall of the splicing groove 204 is installed with a partition plate 205, and the outer wall of the partition plate 205 is provided with a docking groove 206. The partition plate 205 plays a role of separation and fixation, and the docking groove 206 not only increases the functionality of the splicing groove 204, but also facilitates the connection of other components, making the entire structure more stable and flexible.

[0034] Please see the attached Figure 1 , Attachment Figure 2 and attached Figure 4 The inner wall of the lifting mouth 9 is fixedly connected with a lifting ring 10, and the edge of the lifting ring 10 is an arc chamfer. The lifting ring 10 is firmly fixed and connected to the inner wall of the lifting mouth 9 to ensure its stability and reliability. The design of the lifting ring 10 is very delicate, and its edge adopts an arc chamfer design. This design not only makes the appearance of the lifting ring 10 more beautiful, but also can effectively prevent unnecessary damage to the user's hands during use. Through this arc chamfer design, the edge of the lifting ring 10 becomes smoother, thereby improving the overall use experience and safety. The front side of the closing piece 3 A plurality of reinforcement strips 11 are fixedly connected to the rear side of the lifting surface 8, the bottom of the outer wall of the reinforcement strip 11 is fixedly connected to the top of the outer wall of the packaging bag 1, and a plurality of rope rings 12 are fixedly connected at the top edge of the front side of the packaging bag 1, and a draw rope 13 is provided on the inner wall of the rope ring 12. The purpose of the draw rope 13 is to facilitate the user to easily pass through the rope ring 12 when carrying and transporting the packaging bag 1, so as to firmly hold the packaging bag 1 and ensure that it will not accidentally fall off or be damaged during use. This design not only improves the practicality of the packaging bag 1, but also enhances its aesthetics and the user's experience.

[0035] Please see the attached Figure 1 , Attachment Figure 4 and attached Figure 5 The bottom of the front side of the packaging bag 1 is fixedly connected with a transparent film 14, and an easy outlet 15 is provided on the right side of the transparent film 14. The transparent film 14 not only increases the aesthetics of the packaging bag 1, but also has the practical function of placing promotional items. The right part of the transparent film 14 is provided with an easy outlet 15 that is convenient for users to use, making it more convenient for users to take out and replace promotional items, thereby increasing the convenience of use. A plurality of rope rings 16 are fixedly connected at the top edge of the rear side of the packaging bag 1, and a draw rope 17 is provided on the inner wall of the rope ring 16. A brand logo 18 is fixedly connected to the middle part of the rear side of the packaging bag 1, and easy folding surfaces 19 are provided on the left and right sides of the packaging bag 1. The brand logo 18 is very conspicuous and convenient for consumers to identify and remember. In order to facilitate use and carrying, easy folding surfaces 19 are designed on the left and right sides of the packaging bag 1. The easy folding surfaces 19 allow the packaging bag 1 to be easily folded during use, which is convenient for storage and increases the convenience of use.

[0036] Working principle: A closing piece 3 is fixedly connected to the bag opening of the packaging bag 1, and a closing groove 4 and a stabilizing groove 5 are provided on the closing piece 3. The closing surface 7 is passed through the stabilizing groove 5 from the inner wall and then passed through the closing groove 4. Since the closing surface 7 is fixed to the inside of the opposite side of the bag opening of the packaging bag 1, and another lifting surface 8 for balancing the lifting is fixedly connected to the outside of the opposite side, when the closing surface 7 is passed through in this way, the lifting mouth 9 is held to make the structure naturally fall and tighten, and the lifting mouth 9 on the lifting surface 8 is lifted together to stably lift and tighten the structure. This method can quickly and conveniently seal the structure during use, and can also achieve better sealing, complete the rapid closing of the structure, and meet the closing requirements;

[0037] The foam board 201 is fixedly connected to the bottom of the inner wall of the packaging bag 1, which can play an appropriate protective role when loading items. A cross groove 202 is opened on the foam board 201, so that the partition board 1 203 can be inserted into the cross groove 202 to divide the interior into left and right sides. When more partitions are needed, the partition board 205 is inserted. Since the partition board 1 203 is provided with a cross groove 202, the partition board 205 is also provided with a corresponding docking groove 206, so that the partition board 205 can dock and be inserted into the cross groove 202, so that the interior of the structure is divided into four areas, which increases the functionality of various items during use and provides shock-absorbing and buffering protection during movement, meeting the use needs in various situations.
