Description

Technical Field

[0001] This utility model belongs to the field of plastic bag production technology, specifically relating to a back-type plastic bag that is easy to close. Background Technology

[0002] Drawstring bags, also known as drawstring bags, lock bags, or drawstring bags, are packaging bags made by using various ropes to tie the opening tightly to prevent the contents from leaking out. They are widely used for packaging gifts or products.

[0003] A folding drawstring bag, as described in announcement number CN218949921U, includes a bag body, a drawstring ring, and a drawstring cord. The drawstring ring is horizontally positioned at the top of the bag body and sewn to it. The drawstring cord is embedded inside the drawstring ring. A storage handle and a connecting cord are located at the top of the bag body. One end of the connecting cord is fixedly connected to the storage handle, and the other end is sewn to the bag body. The storage handle includes a storage compartment and two knobs, with the knobs mounted opposite each other at the ends of the storage compartment. The storage compartment includes an arc-shaped shell, an arc-shaped closure, a spring, magnet A, and magnet B. The arc-shaped shell has an inner groove. This type of folding drawstring bag, equipped with a storage handle, utilizes the internal space for rotating storage of the drawstring bag. The storage is fast, and after storage, no part of the drawstring bag is exposed, providing protection. Furthermore, the storage handle replaces the cord for lifting, preventing the drawstring bag from digging into the hand when moving.

[0004] In existing drawstring bags, the bag is usually gathered at the opening and then carried by hand. While this method makes it more convenient to carry items to some extent, it does not free up your hands.

[0005] In view of this, the present invention provides a back-type plastic bag that is easy to close, in order to solve the above problems. Utility Model Content

[0006] To solve the above problems, this utility model provides the following technical solution: a back-type plastic bag that is easy to close, comprising a bag body with an opening, and guide channels for a rope to pass through are formed on the inner side of the opening and the inner side of the bag body opposite to the opening. After the rope extends between the guide channels, it forms a carrying strap on both sides of the bag body. When the rope is tightened, the opening and bottom of the bag body are tightened.

[0007] As a preferred embodiment of this utility model of a back-type plastic bag that is easy to close, both ends of the guide channel are provided with through holes that communicate with the surface of the bag body, for the rope to enter and exit the guide channel.

[0008] As a preferred embodiment of the present invention, a back-type plastic bag that is easy to close, the guide channels formed on the inner side of the opening and the inner side of the bag body are respectively the first guide channel and the second guide channel.

[0009] As a preferred embodiment of this utility model of a retractable plastic bag, the rope body comprises: a first rope body and a second rope body.

[0010] As a preferred embodiment of this utility model of a reusable plastic bag, the first rope and the second rope enter the first guide channel from both sides of the bag body, change direction and pass out through the first guide channel, then pass into the second guide channel, change direction and pass out through the second guide channel, and are knotted on both sides of the bag body to form a carrying strap.

[0011] As a preferred embodiment of this utility model of a back-type plastic bag that is easy to close, the first guide channel is formed by folding the opening into the bag body and then heat-pressing it together with the bag body.

[0012] As a preferred embodiment of this utility model of a back-type plastic bag that is easy to close, the second guide channel is formed by folding the bottom surface of the bag inward and then heat-pressing it to the bag body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model extends the first and second ropes into the first and second guide channels, forming shoulder straps on both sides of the bag. When the first and second ropes are tightened, the opening and bottom of the bag can be gathered to form a more aesthetically pleasing "candy" shape, improving its appearance while also allowing the bag to be carried on the back.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model relates to a retractable plastic bag, such as... Figure 1 As shown, it includes a bag body 1 with an opening 2 at the top.

[0022] like Figure 2 As shown, after the edge of the opening 2 of the bag body 1 is folded inward, it is heat-pressed with the inner wall of the bag body 1 along two sealing lines 8 to form a first guide channel 4. At the same time, after the bottom surface of the bag body 1 is folded inward, it is heat-pressed along two sealing lines 8 to form a second guide channel 5.

[0023] Furthermore, both ends of the first guide channel 4 and the second guide channel 5 are provided with through holes 3 that connect to the outer surface of the bag body 1. The first rope 6 and the second rope 7 enter the first guide channel 4 or the second guide channel 5 from the through holes 3 on both sides of the bag body 1, and after changing direction in the first guide channel 4 or the second guide channel 5, they pass out from the through hole 3 on the same side, and then enter the second guide channel 5 or the first guide channel 4 through the other through hole 3 on the same side. After changing direction, they pass out from the through hole 3 on the same side, and the two ends of the first rope 6 and the second rope 7 are tied at both sides of the bag body 1 to form a closed rope.

[0024] like Figure 3 As shown, when in use, by tightening the first rope 6 and the second rope 7, the opening 2 and the bottom of the bag 1 are tightened under the action of force, forming a "candy" shaped structure to improve the appearance. Due to the tightening of the bag 1, the exposed parts of the ropes on both sides of the bag 1 become longer, forming a shoulder strap, which the user can use to carry the bag 1 on their back.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
