Description

Technical Field

[0001] The utility model relates to the technical field of non-woven bags, in particular to a non-woven bag with a stable drawstring. Background Art

[0002] The non-woven bag with stable drawstring is also called drawstring non-woven bag, tight-mouth non-woven bag, lock non-woven bag. It is a packaging bag made of non-woven fabric with various ropes to tighten the bag mouth to prevent the contents from leaking out. It is used in gift and product packaging. In the prior art, the rope used to tighten the bag mouth of the non-woven bag is generally passed through the rope threading portion formed on the upper end of the non-woven bag. In order to enhance the stability of the non-woven bag mouth after tightening, a spring buckle is passed through the rope. The spring buckle is used to fix the tightened rope so that the bag mouth of the non-woven bag remains in a tightened state to prevent the contents from leaking out. However, since the spring buckle relies on the elastic force of the spring to clamp the rope, the fixing force of the rope is weak. Moreover, after a period of use, the spring is prone to fatigue, causing the bag mouth of the non-woven bag to be disassembled during use, resulting in leakage of contents, which is inconvenient for the use of the non-woven bag.

[0022] The following is a combination of the appended examples of the present invention Figure 1-5 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] When the bag is in a state of being out of reach of the user, the bag 32 is clamped in place and the bag 33 is unlocked, so that the bag 33 can be unlocked when the bag is unlocked. When the cam 33 is in the closed position, the cam 33 is in the closed position, and the cam 33 is in the open position, so that the cam 33 is in the closed position and the cam 33 is out of the open position.

[0024] In the above embodiment, the drawstring 2 is closed to drive the string portion 11 to gather, thereby tightening the bag opening 1 to prevent the items in the bag 1 from leaking out. When the drawstring 2 is closed, Figure 5The lock body 31 is fixed with the locking cam 332 and the locking cam 333 is unlocked, and the locking cam 332 is unlocked, so that the locking cam 332 is unlocked. When the bag 1 is closed, the end of the block 32 returns to the first sliding cavity 314 to ensure that the drawstring 2 can smoothly pass through the insertion opening 313 to tighten the bag opening of the bag body 1. After the bag opening of the bag body 1 is tightened into place, the positioning slider 32 is pushed to slide forward in the first sliding cavity 314 so that the end of the positioning slider 32 passes through the port of the first sliding cavity 314 and is stuck between the adjacent teeth 21. Then, the limiting slider 33 is pushed to slide in the second sliding cavity 315 into the first sliding cavity 314 so that the limiting slider 33 is against the large end of the positioning slider 32 and the limiting protrusion 316 is stuck in the limiting groove 331, so that the limiting component 3 is as shown in FIG. Figure 4 When the bag 1 is in the closed position, the locking cam 331 is in the closed position, and the locking cam 332 is in the closed position, so that the locking cam 332 is in the closed position. Figure 5 When the bag is in the closed position, the bag 1 is opened by pulling the drawstring 2 and the bag opening is opened. The bag 1 is then closed by pulling the drawstring 2 and the bag opening is opened by pulling the drawstring 2 and the bag opening is opened. When the drawstring 2 is in the closed position, the bag 1 is opened by pulling the drawstring 2 and the bag opening is opened. When the drawstring 2 is in the closed position, the bag 1 is opened by pulling the drawstring 2 and the bag opening is opened. When the drawstring 2 is in the closed position, the bag 1 is opened by pulling the drawstring 2 and the bag opening is opened. When the drawstring 2 is in the closed position, the bag 1 is opened

[0025] Preferably, the ends of the latching teeth 21 and the latching slider 32 are both in a trench-shaped manner, which strengthens the limiting effect of the latching slider 32 on the cinch band 2 when the latching slider 32 cooperates with the latching teeth 21 .

[0026] Preferably, the connecting frame 31 is composed of a frame body 311 and an end cover 312, the insertion opening 313 is opened on the frame body 311, and the first sliding cavity 314 and the second sliding cavity 315 are surrounded by the frame body 311 and the end cover 312. When assembling the limiting component 3, the positioning slider 32 and the limiting slider 33 are successively placed in the first sliding cavity 314 and the second sliding cavity 315, and then the end cover 312 is buckled on, which facilitates the assembly of the limiting component 3.

[0027] Preferably, the cuff strap 2 and the limiting slider 33 are formed of nylon material, and the frame 311, the end cover 312 and the positioning slider 32 are made of metal material. Based on the characteristics of nylon material, the cuff strap 2 and the limiting slider 33 are ensured to have good strength and toughness. Based on the characteristics of metal material, the frame 311, the end cover 312 and the positioning slider 32 are ensured to have good strength and rigidity. On the premise of ensuring that the limiting component 3 can limit the cuff strap 2, the overall strength of the limiting component 3 is enhanced, thereby enhancing the limiting effect of the limiting component 3 on the cuff strap 2.

[0028] Preferably, a plurality of storage rings 12 for the drawstring 2 to pass through are fixedly connected to the outer surface of the rope threading portion 11. After tightening the drawstring 2, the drawstring 2 is passed through the insertion opening 313, and the tightened rope threading portion 11 is wrapped around the storage ring 12 for storage, so that the overall appearance of the non-woven bag is more beautiful and neat.

[0029] Furthermore, the bag body 1 is connected to a plurality of reinforcing belts 4 which are passed through the lower end of the bag body 1 and wrapped around the bag body 1 .

[0030] Specifically, the end of the reinforcement belt 4 is connected to the bag body 1 through a buckle 5 .

[0031] In the above preferred embodiment, when the reinforcement belt 4 is wrapped around the bag body 1, the reinforcement belt 4 can support the bag body 1, thereby strengthening the strength of the bag body 1 and strengthening the load-bearing performance of the bag body 1. The reinforcement belt 4 connected to the bag body 1 through the buckle 5 can be removed from the bag body 1 when necessary and then connected to the bag body 1 in the form of a straddle on the upper end of the bag body 1, so that the reinforcement belt 4 can be used as a handle, thereby facilitating the use of the non-woven bag.

[0032] Preferably, a plurality of limiting rings 13 are fixedly connected to the bag body 1, and the reinforcing belt 4 passes through the limiting rings 13. The limiting rings 13 limit the movement of the reinforcing belt 4 relative to the bag body 1 when it is wrapped around the bag body 1, so that the reinforcing belt 4 can be more stably maintained in the state of being wrapped around the bag body 1 and support the bag body 1.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
