Description

Technical Field

[0001] This utility model relates to a drawstring bag B for drawstring bag sets, and its application fields include drawstring garbage bags, drawstring garbage bag sets, drawstring tote bags, drawstring tote bag sets, drawstring packaging bags, drawstring packaging bag sets, drawstring food packaging bags, drawstring food packaging bag sets, and other drawstring bags and drawstring bag sets. The drawstring bag used in drawstring bag sets can be made of paper, plastic film, biodegradable materials, composite materials, and other materials. Technical Background

[0002] The existing bag structure (patent number 2022208872997) is more suitable for trash cans with pressure rings. In trash cans without pressure rings, the bag needs to be manually pressed to tear it off when it is removed. This makes the user experience of trash cans without pressure rings poor, and it is also easy to remove the entire bag assembly without pressure rings. Therefore, it needs to be optimized and improved. Summary of the Invention

[0003] The purpose of this utility model is to provide a drawstring bag B for drawstring bag assembly, which eliminates the connecting body between the bag body and the fixing body, so that it can be used in trash cans without pressure rings.

[0004] The technical solution of this utility model is as follows:

[0005] A drawstring bag B for use in drawstring bag assembly is characterized in that: the bag opening is folded inward on both sides to form a double-layer structure; several insulators are located on both outer sides of the bag body, so that the insulators and the double-layer structure formed by the inward folding of the bag body are parallel, forming a three-layer structure; at a certain position below the bag opening, the unfolded layer, the folded layer, and the insulators are heat-sealed together. At this time, the inwardly folded bag body and the unfolded bag body form a cavity, which is a drawstring cavity. A drawstring is threaded through the cavity, and there is a drawstring opening on the cavity. The insulators are located outside the drawstring cavity. The bag body, the drawstring, and the insulators on both sides of the bag body are connected together to form a drawstring assembly. A drawstring bag B is used in a drawstring bag assembly. The bag opening is folded outward on both sides to form a double-layer structure. Several insulators are located on the outer sides of the bag body, so that the insulators and the double-layer structure formed by the outward folding of the bag body are parallel to each other, forming a three-layer structure. At a certain position below the bag opening, the unfolded layer, the folded layer, and the insulators of the bag body are heat-sealed together. At this time, the outward folded bag body and the unfolded bag body form a cavity. This cavity is a drawstring cavity, and a drawstring is threaded through the cavity. There is a drawstring opening on the cavity. The insulators are located on the outer side of the drawstring cavity. The bag body, the drawstring, and the insulators on the left and right sides of the bag body are connected together to form a drawstring bag B for a drawstring bag assembly.

[0006] In one type of drawstring bag assembly, the drawstring bag B has an insulator located on the outermost layer of a three-layer structure. Its function is to isolate the drawstring structure of this drawstring bag from other unused drawstring bags in the drawstring bag assembly. When this drawstring bag is taken out, pulling the drawstring of this drawstring bag will not contact other unused drawstring bags isolated on the outside. Therefore, when taking out the current drawstring bag, other drawstring bags will not be taken out.

[0007] The height of the isolation body is higher than that of the drawstring cavity. This is because the drawstring cavity is within a certain range of the drawstring opening, which is easily accessible to the hand when touching the drawstring. Therefore, there needs to be an isolation area within the reach of the hand near the drawstring opening to prevent the hand from touching the unused drawstring bag located outside the drawstring bag to be retrieved when pulling out the drawstring.

[0008] Depending on production needs and user group requirements, the rope retrieval port on the rope cavity can be located inside the rope cavity or outside the rope cavity. Since there is an isolator on the outside of the rope cavity, it is not necessary to provide an isolation function on the outside of the rope cavity. Therefore, whether the rope retrieval port is inside or outside the rope cavity, the function is the same.

[0009] Specifically, the connection state of the isolator on both sides, from a certain position above the drawstring cavity to the top of the isolator, includes two possibilities: connected and unconnected. Specifically: First, when the bag body, drawstring, and isolator are sealed together on both sides of the bag, a full seal is achieved from the bottom of the bag to the top of the isolator, meaning both sides of the bag are completely sealed. Second, when the bag body, drawstring, and isolator are sealed together on both sides of the bag, a full seal is achieved from the bottom of the bag to a certain position above the drawstring cavity, but the connection from that position above the drawstring cavity to the top of the isolator is not.

[0010] Among them, the distance from a certain position above the pull rope cavity to the top of the isolator is a distance that can be adjusted and selected as needed, for example, from zero milliseconds above the pull rope cavity to the top of the isolator, or from ten millimeters above the pull rope cavity to the top of the isolator.

[0011] The method for assembling drawstring bags is characterized by: nesting and overlapping several drawstring bags, one nested on top of another, to form a drawstring bag group. The innermost drawstring bag is the drawstring bag that can currently hold items. When taking out a drawstring bag, the drawstring bag to be taken out is first manually or automatically separated from the drawstring bag group, and then the drawstring bag is taken out from the drawstring bag group by grasping the drawstring bag or the grasping structure on the drawstring bag.

[0012] Any drawstring bag can be nested and overlapped to form a drawstring bag group. There can be a number of drawstring bags in a group, such as 10, 30, or 100 bags, and more will not be described here.

[0013] The structure of the drawstring bag assembly is characterized by: nesting and overlapping several drawstring bags one on top of another, and forming a drawstring bag assembly by nesting and overlapping them in sequence.

[0014] Attaching a drawstring bag assembly to a trash can is done in the same way as attaching a single trash bag to a trash can; the drawstring bag assembly can be considered as a relatively thick trash bag attached to the trash can.

[0015] During use, if the drawstring bag currently containing trash in the drawstring bag assembly becomes damaged or broken, simply remove the next drawstring bag nested around it. This will remove the damaged drawstring bag from the assembly along with the damaged one, preventing trash from falling into the trash can and soiling it. If the weight of the trash in the current drawstring bag exceeds its weight capacity, simply remove the next trash bag nested around it, along with the current drawstring bag, to strengthen the drawstring bag.

[0016] The advantages of this invention are: it ensures accurate separation of the drawstring bag from the drawstring bag assembly, without pulling out other drawstring bags that do not need to be separated temporarily. This guarantees the reliability and convenience of using the drawstring bag assembly. Attached Figure Description

On the left and right sides of the bag body (100), the bag body, drawstring cavity (202), drawstring (201), and separator (101) are heat-sealed together to form a left sealing edge (304) and a right sealing edge (305). The separator (101) is also sealed together from a certain position above the drawstring cavity (202) to its top position (303), forming a drawstring bag B for a drawstring bag assembly. In the figure, the size and shape of the garbage bag have been appropriately deformed for clarity, but this does not affect the garbage bag structure.

[0029] Figure 4In the middle, the two sides of the bag opening of the bag body (100) are folded inward to form a double-layer structure, forming a folded edge (300). Several insulators (101) are located on both sides of the bag body (100). The double-layer structure formed by the inward folding of the insulators (101) and the bag body (100) is parallel, forming a three-layer structure.

In the figure, the size and shape of the garbage bag have been appropriately deformed for clarity, but this does not affect the garbage bag structure.

[0030] Figure 5 In this process, the first drawstring bag (1) is nested and overlapped on top of the second drawstring bag (1), and then the second drawstring bag (1) is nested and overlapped on top of the third drawstring bag (1), and so on, until the Nth drawstring bag (1) is reached, forming a drawstring bag group. The drawstring bag group is then placed into the trash can, and trash is thrown into the trash bag that can currently hold trash in the drawstring bag group. When a certain amount of trash is filled, the drawstring on the bag is manually pulled, which separates the trash bag, closes the opening, and allows for removal. After removing the trash bag, trash can be thrown into the next drawstring bag that can currently hold trash nested outside the removed trash bag in the drawstring bag group. This process is repeated until all the drawstring bags in the drawstring bag group are removed. In the figure, the size and shape of the drawstring bag group have been appropriately deformed for clarity, and the trash bags are in an open state, but this does not affect the structure of the drawstring bag group.

[0031] Figure 6 In this case, the drawstring bag assembly (2) is installed on the trash can (3). The installation method is to put the drawstring bag assembly (2) over the mouth of the trash can (3), and fold the part of the drawstring bag assembly (2) from the mouth to the drawstring chamber outward to the outside of the mouth of the trash can (3). This completes the installation of the drawstring bag assembly on the trash can. After the trash bag that can hold trash is filled with trash, manually pull the drawstring to remove the drawstring bag from the drawstring bag assembly, which is equivalent to removing it from the trash can (3). The installation of other trash cans will not be described here.
