[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Please refer to Figures 1 to 5 The present embodiment provides a packaging bag, which comprises a bag body 1 with an opening 10, a supporting structure for supporting the opening 10 of the bag body 1, and a bag cover 2 for closing the opening 10. The supporting structure is arranged on the bag body 1, and the bag cover 2 is connected to the bag body 1 through a lock catch structure. The bag body 1 has an opening 10, or a bag mouth, through which objects can be loaded into the bag body 1. In general, when loading objects into the bag, one hand supports the opening 10 of the bag body 1, and the other hand loads objects into the bag. Alternatively, within a short time of supporting the bag mouth, objects are loaded into the bag before the bag mouth naturally closes to a small size. After the bag mouth closes, the bag mouth needs to be supported again. In practical applications, this is relatively troublesome, especially for large kraft paper packaging bags that can hold several dozen kilograms of objects, such as large kraft paper bags for holding grass and leaves. The present packaging bag is small and flat when folded, and the height of the packaging bag after being opened can reach half a person. The bag mouth is extremely easy to naturally close, which leads to inconvenience in use. For such a packaging bag, the present embodiment improves it by designing a supporting structure at the opening 10 of the bag body 1. The supporting structure can be made of the same material as the bag body 1, can be detachably installed on the bag body 1, or can be integrally formed on the bag body 1. The supporting structure can skillfully support the opening 10 of the bag body 1, or maintain the opening 10 of the bag body 1 from naturally closing, so that people can conveniently load grass or leaves into the bag. After loading is completed, the opening 10 of the bag body 1 can be closed by the bag cover 2, without the need to find other measures to close the opening 10, so that the present packaging bag is more efficient to use. After the bag cover 2 is closed, it can also prevent rainwater from entering the bag body 1. In order to avoid the bag cover 2 from easily opening the opening 10, a lock catch structure can be designed to connect the bag cover 2 to the bag body 1.

[0029] Please refer to Figures 1 to 5 After the bag cover 2 is covered on the bag body 1, the top of the bag body 1 is flat. Compared with Figure 6Compared with the last generation of packaging bag product of the applicant (application number 2024231411004), the present application can achieve a flat top of the bag body 1 after sealing the bag cover 2, thereby improving the storage space at the bag opening and improving the storage capacity of the packaging bag.

[0030] Please refer to Figures 1 to 5 The locking structure includes an insertion part and a locking part that can lock the insertion part. The insertion part is provided on the bag cover 2, and the locking part is provided on the bag body 1, or the insertion part is provided on the bag body 1, and the locking part is provided on the bag cover 2. The locking structure is refined into a locking part and an insertion part, which can realize the connection of the bag cover 2 and the bag body 1 after cooperation. As for the position of the locking part and the insertion part, the insertion part can be provided on the bag body 1 or the bag cover 2, and the locking part is the same. For example, if the insertion part is provided on the bag body 1, the locking part can be provided on the bag cover 2. If the insertion part is provided on the bag cover 2, the locking part can be provided on the bag body 1. Both are acceptable. The embodiment shown in the attached drawings is that the insertion part is provided on the bag body 1, and the locking part is provided on the bag cover 2.

[0031] Refine the insertion part and the locking part mentioned above. Please refer to Figures 1 to 5 The insertion part includes a latch 3, and the locking part includes a lock strap 4 that can be provided on the bag body 1 or the bag cover 2. The lock strap 4 and the bag body 1 or the bag cover 2 have a locking interval for the insertion of the latch 3. The latch 3 and the lock strap 4 can be used in cooperation. The lock strap 4 can be in the form of a long strip and can be attached to the bag body 1 or integrally formed on the bag body 1. It can form a locking interval for the insertion of the latch 3 by cooperating with the bag body 1. The latch 3 and the lock strap 4 used in the present embodiment are made of degradable materials, such as materials similar to kraft paper bags. The bag body 1, the bag cover 2, the support structure, etc. are also the same. In this way, the packaging bag can be buried underground for biological degradation. The packaging bag is usually used to store some fallen leaves, grass and other plants, so the treatment method is usually underground burial. Of course, in addition to the structure of the latch 3 and the lock strap 4, other forms of lock connection can also be used, such as the lock strap 4 can adopt the form of a clamping groove, and it is not limited to a strip-shaped strap. The latch 3 can also not be limited to the form of a pin body, and can adopt, for example, a T-shaped structure, a cross-shaped structure, or other shapes to cooperate with the lock strap 4 to achieve locking.

[0032] Please refer to Figures 1 to 5The inner wall of the band body of the lock band 4 and / or the outer wall of the pin body of the latch 3 is provided with a friction structure 5. By refining the friction structure 5, the locking degree of the insertion part and the locking part can be improved, and such a lock band can automatically adjust the locking position to adapt to different capacity states. The drawings of the embodiment show that the friction structure 5 is designed on the pin body of the latch 3, and the friction structure 5 can also be provided on the inner wall of the band body of the lock band 4, or one of the two is used and the other is not used, but the friction force is greater than that of the smooth surface. By improving the friction force, the locking degree of the latch 3 and the lock band 4 is improved, so that the latch 3 cannot easily and naturally slide out of the lock band 4. In actual use, some force is needed to insert or extract the latch 3 into or out of the lock band 4, rather than being inserted or extracted without obstacles. The friction structure 5 can be a notch formed on the edge of the latch 3 or the lock band 4 to form a sawtooth, or it can be another design of a sawtooth component, or it can be a groove structure designed on the pin body and / or the band body. The purpose is to improve the friction force. Preferably, the sawtooth can be provided on one side or both sides of the edge of the pin body of the latch 3, and the sawtooth can be provided on one side or both sides of the edge of the band body of the lock band 4.

[0033] Please refer to Figures 1 to 5 The latch 3 is a flexible and bendable structure. The latch 3 is made of kraft paper, which is soft and bendable, so it is convenient to bend and insert into the lock band 4 like Figure 2 、 Figure 3 and Figure 4 .

[0034] Please refer to Figures 1 to 5 The bag cover 2 includes at least one cover piece, and the cover piece covers the opening 10. The bag cover 2 can be refined into a cover piece, and one cover piece can achieve covering. Two cover pieces are used in the embodiment, which are defined as the first cover piece 20 and the second cover piece 21 for convenience of description. The latch 3 on the first cover piece 20 is first bent and inserted into the lock band 4 on the inner wall of the bag body 1, and then the latch 3 on the second cover piece 21 is bent and inserted into the lock band 4 on the outer wall of the bag body 1. The number of latches 3 and lock bands 4 can be selected as needed, and one or more can be used. The embodiment shows that there are two latches 3 on the first cover piece 20, and there are two lock bands 4 on the inner wall of the bag body 1 corresponding to the two latches 3. There is one latch 3 on the second cover piece 21, and there is one lock band 4 on the outer wall of the bag body 1 corresponding to the latch 3.

[0035] Please refer to Figures 1 to 5 The bag body 1, the bag cover 2, the support structure and / or the lock structure are degradable structures. The degradable structure can be made of existing kraft paper or other biodegradable materials, and can also be made of other materials. The embodiment does not limit this.

[0036] Please refer to Figures 1 to 5The supporting structure includes reinforcing ribs 6 located on the bag body 1 near the edge of the opening 10. The supporting structure is further defined as reinforcing ribs 6, which can be adhesive tape, preferably made of a biodegradable material. The reinforcing ribs 6 can be detachably connected or integrally formed onto the bag body 1. Detachable connections include, but are not limited to, adhesive bonding and snap-fitting.

[0037] Please see Figures 1 to 5 The bottom of the bag body 1 is a waterproof bottom 7. Designing the bottom of the bag body 1 to be waterproof 7 can extend the service life of this packaging bag. Specifically, the waterproof bottom 7 can be designed by attaching a waterproof layer, such as a waterproof membrane or waterproof board, to the outer bottom wall of an existing kraft paper bag. However, this waterproof layer also needs to be made of a biodegradable material, so that when the packaging bag is filled with biodegradable materials such as grass and fallen leaves, it can be buried underground for biodegradation. The waterproof bottom can be integrally formed with the bag body 1 or it can be detached; this embodiment does not impose any restrictions on this.

[0038] In another embodiment, the packaging bag may also be designed with a handle for easy lifting. Preferably, a film may be attached near the bottom of the packaging bag to increase its strength, allowing it to be dragged on the ground without breaking, and also improving ease of use. The bag body 1 has crease lines for easy folding and storage.

[0039] The above embodiments detail the two usage states of this packaging bag, from Figures 1 to 5 Figures 1 to 5 The process of sealing this packaging bag is shown. The aforementioned support structure ensures that the opening 10 will not naturally close due to prolonged folding, facilitating the filling process. Once full, the bag cap 2 is placed over the opening 10, and the cap 2 is locked to the bag body 1 using the locking mechanism to seal the opening 10. Furthermore, because the bottom of this packaging bag is designed to be waterproof (7), even if it contains wet grass or leaves, or is placed on a wet surface, the bottom of the bag will remain intact for a long time, extending its lifespan. This packaging bag represents a minor improvement over existing packaging bags, is low-cost, yet improves efficiency, reduces damage, and is convenient for filling with grass or leaves. The bag's durability also prevents it from scattering when others collect it, significantly enhancing convenience.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
