[0002] In recent years, with the rapid development of the global economy and the rapid increase in the population, the scale of cities has been continuously expanding, resulting in a sharp rise in the amount of urban domestic waste. The problem of urban domestic waste is increasingly deteriorating into a global crisis. Problems such as land erosion and environmental pollution caused by "garbage besieging the city" not only seriously threaten the health of the public, but also have become one of the factors affecting and restricting the sustainable development of cities in China and even the world. To solve the problem of "garbage besieging the city", the primary task is to achieve the reduction of urban domestic waste at the source, and to complete the resource utilization and harmless treatment of garbage. Therefore, promoting the classification of domestic waste has become an urgent task and an inevitable trend.

[0003] On July 1, 2019, the "Shanghai Domestic Waste Management Regulations" was officially implemented in Shanghai. This regulation requires various types of garbage to be separately put, namely, wet garbage, dry garbage, recyclables and hazardous waste, a total of 4 categories. Among them, wet garbage requires bag-breaking treatment, that is, users need to tear the garbage bag or open the bag mouth and hold the bottom upside down to pour all the garbage in the bag into the wet garbage bin, and then put the garbage bag into the dry garbage bin. There may be sewage seeping out from the bottom of the wet garbage bag, and the garbage in the bag may also splash onto the hands or even clothes during the treatment process, which is unhygienic and has a bad smell. Summary of the Invention

[0004] Currently, although there is a dumping belt provided on one side of the garbage bag, when dumping garbage, users hold one end of the dumping belt and tear it to achieve the dumping of the garbage bag. However, during the tearing process, due to uneven gravity, the garbage bag is likely to be skewed, and users may still touch the tilted garbage. Moreover, this kind of garbage bag still uses the conventional packing method, which is not convenient, and the dumping bag cannot simultaneously achieve the packing function.

[0005] In order to at least partially solve the above-mentioned and other potential problems, an embodiment of the present disclosure provides a garbage bag, which provides a drawstring cavity at the opening of the bag body, and a drawstring member is provided in the drawstring cavity. The user can easily tighten the bag opening by grasping the two ends of the drawstring member exposed from the left drawstring hole and the right drawstring hole respectively and applying force to draw them out at the same time. The method is simple and convenient, and the bag opening has a high tightening degree, and the smell of garbage corruption is not easy to diffuse from the bag opening. The parts of the drawstring member exposed from the left drawstring hole and the right drawstring hole are respectively formed with a left drawstring sealing edge and a right drawstring sealing edge. When it is necessary to dump the garbage, a certain force is applied to break it, and then tearing along the two sides of the garbage bag can be continued to easily realize the dumping of the garbage. The operation is simple, clean and hygienic, and the garbage bag body has a simple structure and is easy to manufacture.

[0006] In the first aspect of the present disclosure, a garbage bag is provided.

[0007] According to the embodiments of the present disclosure, a drawstring cavity is provided at the opening of the bag body, and a drawstring member is provided in the drawstring cavity. The user can easily tighten the bag opening by grasping the two ends of the drawstring member exposed from the left drawstring hole and the right drawstring hole respectively and applying force to draw them out at the same time. The operation is simple and convenient, and the bag opening has a high tightening degree, and the smell of garbage corruption is not easy to diffuse from the bag opening. The parts of the drawstring member exposed from the left drawstring hole and the right drawstring hole are respectively formed with a left drawstring sealing edge and a right drawstring sealing edge. When it is necessary to dump garbage, a certain force is applied to break it, and then tearing along the two sides of the garbage bag is continued to realize the dumping of garbage easily. The operation is simple, clean and hygienic, and the garbage bag body has a simple structure and is easy to manufacture.

[0008] In a second aspect of the present disclosure, a garbage bag assembly is provided. The garbage bag assembly is composed of at least two of the above-mentioned garbage bags; a first bag body, which has a semi-closed first cavity formed inside for holding garbage; the two sides of the first bag body are sealed to form a first left sealing edge and a first right sealing edge; the first cavity has a first opening defined by its periphery, which is configured to allow garbage to enter the first cavity; a first drawstring cavity, which is a hollow channel laid along the periphery of the first opening; a first drawstring member, which is threaded through the hollow channel and is configured to be movable and retractable within the first drawstring cavity, and the first drawstring member can tighten the first opening to close the first cavity; a first left drawstring hole, which is a notch opened on the left surface of the first drawstring cavity and is configured to allow the first drawstring member to be movably drawn out from the notch, and the part of the first drawstring member exposed from the notch forms a first drawstring left sealing edge; a first right drawstring hole, which is a notch opened on the right surface of the first drawstring cavity and is configured to allow the first drawstring member to be movably drawn out from the notch, and the part of the first drawstring member exposed from the notch forms a first drawstring right sealing edge; a second bag body, which has a semi-closed second cavity formed inside for holding garbage; the two sides of the second bag body are sealed to form a second left sealing edge and a second right sealing edge; the second cavity has a second opening defined by its periphery, which is configured to allow garbage to enter the second cavity; a second drawstring cavity, which is a hollow channel laid along the periphery of the second opening; a second drawstring member, which is threaded through the hollow channel and is configured to be movable and retractable within the second drawstring cavity, and the second drawstring member can tighten the second opening to close the second cavity; a second left drawstring hole, which is a notch opened on the left surface of the second drawstring cavity and is configured to allow the second drawstring member to be movably drawn out from the notch, and the part of the second drawstring member exposed from the notch forms a second drawstring left sealing edge; a second right drawstring hole, which is a notch opened on the right surface of the second drawstring cavity and is configured to allow the second drawstring member to be movably drawn out from the notch, and the part of the second drawstring member exposed from the notch forms a second drawstring right sealing edge; the first right sealing edge is connected to the second left sealing edge, and a first pre-cutting line is provided at the connection part; the first drawstring right sealing edge is connected to the second drawstring left sealing edge, and a second pre-cutting line is provided at the connection part.

[0009] In this way, by providing the first pre-cutting line and the second pre-cutting line, when the user needs to detach the garbage bag from the garbage bag assembly, only by tearing along the two pre-cutting lines respectively, the separation between the garbage bags can be achieved. The operation is simple, convenient and fast.

[0010] In some embodiments, the first pre-cutting line is located between the first right sealing edge and the second left sealing edge, and the distance between the first pre-cutting line and the two sealing edges is equal.
