Description
Technical Field
[0001] This utility model belongs to the field of nonwoven bag technology, and in particular relates to a nonwoven bag with a self-sealing opening structure. Background Technology
[0002] Non-woven bags, also known as non-woven fabric bags or non-woven cloth bags, are a green product with characteristics such as toughness and durability, beautiful appearance, and good breathability.
[0003] Existing non-woven bags typically have an open design that cannot be sealed or uses a zipper for sealing. The unsealed design makes it easy for the contents to fall out, and it also provides poor privacy and low security. The zipper design is prone to quality problems, which can lead to zipper damage, short service life, or even failure to open and close properly, rendering the bag unusable. Therefore, we propose a non-woven bag with a self-sealing opening structure. Utility Model Content
[0004] The purpose of this utility model is to provide a non-woven bag with a self-sealing opening structure. By setting a sealing component, specifically, the user presses the top opening of the non-woven bag, causing two sets of sealing parts on the inner wall of the non-woven bag to align. The metal pieces on the two plastic sleeves are attracted together by the magnetic attraction, thereby self-sealing the top opening of the non-woven bag. This solves the problem that the opening of existing non-woven bags is usually not sealable or uses a zipper for sealing. The lack of a seal makes it easy for the contents to fall out, and it also results in poor privacy and low security. The zipper is also prone to damage due to quality issues.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a non-woven bag with a self-sealing opening structure, including a non-woven bag, which is used to store items and makes it convenient for users to carry.
[0007] The nonwoven bag includes a sealing section inside, which is configured in two sets. These two sets of sealing sections are installed on the front and back of the inner wall of the nonwoven bag. The sealing section is used to seal the opening at the top of the nonwoven bag; and
[0008] The opening support is installed on the left and right sides inside the non-woven bag and is used to automatically open the top opening of the non-woven bag.
[0009] The opening at the top of the non-woven bag is quickly sealed by pressing, and then the opening at the top of the non-woven bag is quickly opened by pulling through the opening support.
[0010] Furthermore, the sealing portion includes a sealing assembly for sealing the front and back of the opening at the top of the nonwoven bag.
[0011] A magnetic suction component is installed inside the sealing component, and the magnetic suction component uses magnetic attraction to attract the two sets of sealing parts.
[0012] The sealing component is used to fix the nonwoven bag to the inner opening and is long and narrow.
[0013] Furthermore, the support portion includes a spreading component, which is used to fix on the left and right sides of the opening on the nonwoven bag and to support the limiting component;
[0014] A limiting component is installed inside the spreading component and is used to limit the movement of the spreading component;
[0015] The limiting component is used to limit the movement of the spreading component, so that the spreading component moves in a linear manner.
[0016] Furthermore, the sealing assembly includes a plastic sleeve fixedly connected to the inner wall of the non-woven bag, and a rubber sleeve is fitted on the outer side of the plastic sleeve;
[0017] The rubber sleeve serves a protective function and reduces friction during sealing.
[0018] The magnetic assembly includes a metal sheet embedded inside a plastic sleeve, with several magnets embedded between the metal sheet and the plastic sleeve; the design of the metal sheet increases the strength of the plastic sleeve, prevents bending, and makes the non-woven bag flatter after sealing.
[0019] The magnet is used to generate magnetic force on the metal sheet, so that when the two sets of sealing parts are attached, the two metal sheets are attracted and fixed by magnetic force, thus completing the sealing.
[0020] Furthermore, the expansion assembly includes a plastic fixing block fixedly connected to the inner wall side of the non-woven bag. The plastic fixing block is provided with plastic push rods on both the front and back sides. A plastic slide rod is fixedly connected to the side of the two plastic push rods that are close to each other. Limiting grooves are provided on both the front and back sides of the plastic fixing block. The plastic push rods, plastic slide rods and plastic fixing blocks are all made of plastic, which can achieve the required functions while reducing the cost of use.
[0021] The plastic push rod is round and vertical, and the round shape is used to reduce friction.
[0022] Furthermore, the limiting component includes a plastic limiting block fixedly connected to the tail end of the plastic slide rod. A square groove is provided at the center of both the plastic limiting block and the plastic slide rod. A plastic square rod is fixedly connected to the inner wall of the limiting groove, and a spring is sleeved on the outer side of the plastic square rod.
[0023] The spring is connected to the surface of the plastic limiting block on the side facing the plastic limiting block, and connected to the inner wall of the limiting groove on the side away from the plastic limiting block. The plastic slide rod slides through the plastic fixing block and extends into the limiting groove. The plastic push rod is used to squeeze the spring when it drives the plastic slide rod to retract.
[0024] Furthermore, the plastic square rod is square in shape, and it slides and limits the movement of the plastic slide rod in a square groove. The plastic square rod is used to limit the movement of the plastic slide rod, so that the plastic slide rod moves in a linear manner.
[0025] This utility model has the following beneficial effects:
[0026] 1. This utility model features a sealing component. Specifically, when the user presses the top opening of the non-woven bag, the two sets of sealing parts on the inner wall of the non-woven bag align. The metal pieces on the two plastic sleeves are attracted together by the magnetic attraction of the magnets, thereby self-sealing the top opening of the non-woven bag. This quickly seals the opening of the non-woven bag, improving privacy and security, and avoiding the damage caused by using zippers.
[0027] 2. This utility model features a support component. Specifically, after the top of the non-woven bag is sealed, the plastic push rod is in a retracted state while the spring is compressed. Pulling the opening at the top of the non-woven bag causes the two sets of seals to separate. The elasticity of the spring causes the plastic push rod to spring back to its original position, opening the opening of the non-woven bag automatically. This makes the operation convenient and easy to use.
[0028] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0037] 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 scope of protection of the present utility model.
[0038] Please see Figures 1-5 As shown, this utility model is a non-woven bag with a self-sealing opening structure, including a non-woven bag 1, which is used to store items so that users can carry them easily.
[0039] The nonwoven bag 1 includes a sealing section 2 inside. The sealing section 2 is configured in two sets, installed on the front and back of the inner wall of the nonwoven bag 1. The sealing section 2 is used to seal the opening at the top of the nonwoven bag 1; and
[0040] The opening support 3 is installed on the left and right sides inside the non-woven bag 1. The opening support 3 is used to automatically open the top opening of the non-woven bag 1.
[0041] The opening at the top of the nonwoven bag 1 is quickly sealed by pressing, and then the opening at the top of the nonwoven bag 1 is quickly opened by pulling through the opening support 3.
[0042] The sealing part 2 includes a sealing assembly 21, which is used to seal the front and back of the opening at the top of the nonwoven bag 1.
[0043] Magnetic component 22 is installed inside the sealing component 21. The magnetic component 22 uses magnetic attraction to attract the two sets of sealing parts 2.
[0044] The sealing component 21 is used to fix the nonwoven bag 1 at the inner opening and is long and narrow.
[0045] The opening support 3 includes an opening component 31, which is used to fix the opening on the left and right sides of the nonwoven bag 1 and to support the limiting component 32.
[0046] Limiting component 32 is installed inside the spreading component 31 and is used to limit the movement of the spreading component 31;
[0047] The limiting component 32 is used to limit the movement of the spreading component 31, so that the spreading component 31 moves in a linear manner.
[0048] The sealing assembly 21 includes a plastic sleeve 211 fixedly connected to the inner wall of the nonwoven bag 1, and a rubber sleeve 212 is fitted on the outer side of the plastic sleeve 211.
[0049] Among them, the rubber sleeve 212 is used to provide protection and reduce friction during sealing;
[0050] The magnetic component 22 includes a metal sheet 221 embedded inside the plastic sleeve 211, and a plurality of magnets 222 are embedded between the metal sheet 221 and the plastic sleeve 211.
[0051] The magnet 222 is used to generate magnetic force on the metal sheet 221, so that when the two sets of sealing parts 2 are attached, the two metal sheets 221 are magnetically attracted and fixed, thus completing the sealing. When the user presses the top opening of the non-woven bag 1, the two sets of sealing parts 2 on the inner wall of the non-woven bag 1 are aligned. The metal sheets 221 on the two plastic sleeves 211 will be attracted together by the magnetic attraction of the magnet 222, thereby self-sealing the top opening of the non-woven bag 1. This can quickly seal the opening of the non-woven bag 1, which not only improves privacy and security, but also avoids the problem of damage caused by using zippers.
[0052] The expansion component 31 includes a plastic fixing block 311 fixedly connected to the inner wall side of the non-woven bag 1. The plastic fixing block 311 is provided with plastic push rods 312 on both the front and back sides. A plastic slide rod 313 is fixedly connected to the side of the two plastic push rods 312 that are close to each other. The plastic fixing block 311 is provided with a limit slide groove 314 on both the front and back sides.
[0053] The plastic push rod 312 is round and vertical, and the round shape is used to reduce friction. After the top of the non-woven bag 1 is sealed, the plastic push rod 312 is in a retracted state, while the spring 323 is in a compressed state. Pulling the opening at the top of the non-woven bag 1 causes the two sets of sealing parts 2 to separate. Under the elastic action of the spring 323, the plastic push rod 312 rebounds and resets, opening the opening of the non-woven bag 1, so that the opening opens automatically. The operation is convenient and easy to use.
[0054] The limiting component 32 includes a plastic limiting block 321 fixedly connected to the tail end of the plastic slide bar 313. A square groove 324 is provided at the center of both the plastic limiting block 321 and the plastic slide bar 313. A plastic square rod 322 is fixedly connected to the inner wall of the limiting groove 314. A spring 323 is sleeved on the outer side of the plastic square rod 322.
[0055] The side of the spring 323 facing the plastic limiting block 321 is connected to the surface of the plastic limiting block 321, and the side of the spring 323 away from the plastic limiting block 321 is connected to the inner wall of the limiting groove 314. The plastic slide rod 313 slides through the plastic fixing block 311 and extends into the limiting groove 314. The plastic push rod 312 is used to squeeze the spring 323 when it drives the plastic slide rod 313 to retract.
[0056] The plastic square rod 322 is square in shape and slides and limits with the square groove 324. The plastic square rod 322 is used to limit the plastic slide rod 313 so that the plastic slide rod 313 moves in a linear manner.
[0057] One specific application of this embodiment is:
[0058] When it is necessary to seal the non-woven bag 1, the user presses the top opening of the non-woven bag 1, so that the two sets of sealing parts 2 on the inner wall of the non-woven bag 1 are aligned. At this time, the metal pieces 221 on the two plastic sleeves 211 will be attracted together by the magnetic attraction of the magnet 222, thereby sealing the top opening of the non-woven bag 1. The rubber sleeve 212 is used to protect and reduce the direct contact and friction between the two metal pieces 221. The opening of the non-woven bag 1 can be sealed quickly by magnetic attraction, which not only improves privacy and security, but also avoids the problem of damage caused by using zippers.
[0059] Meanwhile, when the non-woven bag 1 is sealed, the top of the non-woven bag 1 will shrink due to the sealing process, thus pushing the plastic push rod 312. At this time, the plastic slide rod 313 slides in the limiting groove 314 in the plastic fixing block 311, and both the plastic slide rod 313 and the plastic limiting block 321 slide on the plastic square rod 322 through the square groove 324, while the spring 323 is squeezed. At this time, the plastic push rod 312 is in a retracted state. When it is necessary to open the opening at the top of the non-woven bag 1, the opening at the top of the non-woven bag 1 is pulled forcefully to disengage the two sets of sealing parts 2. At this time, the plastic push rod 312 is not limited and retracted. Under the elastic action of the spring 323, the plastic push rod 312 rebounds and resets. After the plastic push rod 312 resets, it opens the opening of the non-woven bag 1, thus automatically opening the opening on the non-woven bag 1, which is more efficient and convenient to operate.
