Description

Technical Field

[0001] This utility model relates to the field of packaging design and manufacturing technology, and in particular to paper bags with tear-resistant reinforced handles. Background Technology

[0002] Paper bags are bags made of paper, usually kraft paper, white cardboard, or other types of paper. The production process of paper bags includes steps such as paper cutting, printing, folding, and pasting. They are mainly used for shopping, packaging, and document storage. Paper bags with tear-resistant reinforced handles can prevent the handles and the paper bag from tearing. However, traditional paper bags with tear-resistant reinforced handles have insufficient paper strength, and there is a contradiction between the complexity and cost of the reinforcement process, as well as poor reusability. In order to achieve multi-sided reuse of paper bags, new types of paper bags with tear-resistant reinforced handles are used.

[0003] Traditional paper bags limit their application in scenarios involving heavy items. When the items are heavy or the paper bag has been used for a long time, the bag is prone to breakage due to the downward pressure of the items. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a paper bag with a tear-resistant reinforced handle structure, which aims to improve the problem that traditional paper bags limit the application range of paper bags in scenarios where they are used to carry heavy items. When the items are heavy or the paper bag has been used for a long time, the bag body is prone to breakage because it cannot withstand the downward pressure of the items.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A paper bag with a tear-resistant reinforced handle structure includes a paper bag body. The inner wall of the paper bag body has a first circular hole, which is circular. The inner wall of the paper bag body also has a second circular hole, which is circular. The paper bag body includes a kraft paper layer. The outer walls of both sides of the kraft paper layer are coated with a wax coating. The outer walls of the wax coating on both sides are coated with a polyurethane coating. The inner wall of the first circular hole is provided with a handle assembly. The handle assembly is used to lift the paper bag body and share the downward force of the items in the paper bag body.

[0007] Preferably, the handle assembly includes a handle rope, the outer wall of which is slidably connected to the inner wall of the first circular hole, and the outer wall of the handle rope is slidably connected to the outer wall of the second circular hole.

[0008] Preferably, the handle rope comprises a fiber rope, the outer wall of which is provided with kraft paper rope, the outer wall of which is provided with an acrylic coating, and the outer wall of the handle rope is provided with a reinforcing component for strengthening the overall strength of the paper bag body.

[0009] Preferably, the reinforcing component includes a cardboard, the inner wall of which is slidably connected to the outer wall of the handle rope, the outer wall of which is fixedly connected to the inner wall of the paper bag body, and a reinforcing strip fixedly connected to the upper surface of the cardboard, the inner wall of which is slidably connected to the outer wall of the handle rope, and the outer wall of which is fixedly connected to the inner wall of the paper bag body.

[0010] Preferably, the inner wall of the cardboard is provided with a first through hole, the size of which is the diameter of the handle rope, and the first through hole is used to allow the handle rope to pass through.

[0011] Preferably, the inner wall of the reinforcing strip has a second through hole, the size of which is the diameter of the handle rope, and the second through hole is used to allow the handle rope to pass through.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the handle rope is first passed through the first round hole from the outside, and then stretched to the position of the second round hole and passed through the second round hole from the inside. The operation is repeated so that the handle rope is inserted into the paper bag body. This structure can share the downward force of the items in the paper bag body through the rope, thereby preventing the paper bag from breaking.

[0014] 2. In this utility model, applying a wax coating to both sides of the kraft paper layer can make the surface of the paper bag smoother and enhance its moisture-proof and tear-resistant properties. Applying a polyurethane coating to the surface of the wax coating can enhance the waterproof and stain-resistant capabilities of the paper bag and prevent the contents from being contaminated. The handle rope is composed of fiber rope, kraft paper rope, and acrylic coating, which can enhance the tensile strength of the handle rope.

[0015] 3. In this utility model, setting a cardboard at the bottom of the paper bag body can enhance the load-bearing capacity of the bottom of the paper bag body, and setting a reinforcing strip on the inner side of the paper bag body can enhance the strength of the side of the paper bag body and prevent the contents from tearing the paper bag body.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides: a paper bag with a tear-resistant reinforced handle structure, including a paper bag body 1, a first circular hole 11 with a circular shape on the inner wall of the paper bag body 1, a second circular hole 12 with a circular shape on the inner wall of the paper bag body 1, the paper bag body 1 including a kraft paper layer 13, a wax coating 14 on both outer walls of the kraft paper layer 13, a polyurethane coating 15 on the outer walls of both outer walls of the wax coating 14, and a handle assembly 2 on the inner wall of the first circular hole 11. The handle assembly 2 is used to lift the paper bag body 1 and share the downward force of the items in the paper bag body 1.

[0025] Specifically, the first round hole 11 and the second round hole 12 are used to allow the handle rope 21 to be threaded through the inside of the paper bag body 1, thereby reinforcing the bottom of the paper bag body 1. At the same time, the length of the handle rope 21 can be adjusted according to the size of the object in the paper bag body 1, so that the paper bag can be used for objects of different sizes. The kraft paper layer 13 serves as the base of the paper bag body 1. The outer wax coating layer 14 makes the surface of the paper bag body 1 smoother and enhances the tear resistance and water resistance of the paper bag body 1. The outermost polyurethane coating layer 15 protects the wax coating layer 14 and the kraft paper layer 13, achieving the effect of waterproofing and stain resistance.

[0026] Reference Figure 1 and Figure 4The handle assembly 2 includes a handle rope 21, the outer wall of which is slidably connected to the inner wall of the first circular hole 11 and the outer wall of the handle rope 21 is slidably connected to the outer wall of the second circular hole 12; the handle rope 21 includes a fiber rope 22, the outer wall of which is provided with a kraft paper rope 23, the outer wall of which is provided with an acrylic coating 24, and the outer wall of the handle rope 21 is provided with a reinforcing component 3, which is used to strengthen the overall strength of the paper bag body 1;

[0027] Specifically, the handle rope 21 is used to initially reinforce the paper bag body 1. Based on the fiber rope 22, the kraft paper rope 23 can protect the fiber rope 22, and the acrylic coating 24 can make the handle part have a better feel when people lift the paper bag.

[0028] Reference Figure 1 and Figure 5 The reinforcing component 3 includes a cardboard 31, the inner wall of which is slidably connected to the outer wall of the handle rope 21, and the outer wall of which is fixedly connected to the inner wall of the paper bag body 1. A reinforcing strip 32 is fixedly connected to the upper surface of the cardboard 31, the inner wall of which is slidably connected to the outer wall of the handle rope 21, and the outer wall of which is fixedly connected to the inner wall of the paper bag body 1. A first through hole is provided in the inner wall of the cardboard 31, the size of which is the diameter of the handle rope 21, and the first through hole is used for the handle rope 21 to pass through. A second through hole is provided in the inner wall of the reinforcing strip 32, the size of which is the diameter of the handle rope 21, and the second through hole is used for the handle rope 21 to pass through.

[0029] Specifically, a cardboard 31 and a reinforcing strip 32 are provided on the inner wall of the paper bag body 1. By placing the cardboard 31 at the bottom of the paper bag body 1, the load-bearing capacity of the bottom of the paper bag body 1 can be strengthened. The reinforcing strip 32 is fixed to the side of the paper bag body 1 to strengthen the side strength and prevent the paper bag from tearing from the side.

[0030] Working principle: When the device is needed, the handle rope 21 is passed through the first round hole 11 inside the paper bag body 1, then through the second round hole 12 to the outside, and then through the second round hole 12 on the other side back into the paper bag body 1, thus providing support at the bottom of the paper bag body 1 and strengthening the bottom of the paper bag body 1. The paper bag is composed of a wax coating 14 that enhances surface gloss and tear resistance, a polyurethane coating 15 that provides secondary internal and external waterproofing, and a kraft paper layer 13 with high tensile strength. This assembly enables the paper bag to bear relatively heavy items. The handle part is reinforced with fiber rope 22, kraft paper rope 23, and acrylic coating 24 to enhance the tensile strength of the handle rope 21. To achieve the effect of making the lifting part suitable for lifting heavy items, a cardboard 31 is set at the bottom of the paper bag body 1 to strengthen the bottom of the paper bag body 1. The reinforcing strips 32 on the cardboard 31 are fixed to the side of the paper bag body 1 to reinforce the side of the paper bag body 1, thereby strengthening the side strength of the paper bag body 1. This component can achieve a secondary strengthening effect on the load-bearing capacity of the paper bag body 1. This structure not only solves the problem that traditional paper bags limit the application range of paper bags in scenarios where they are used to carry heavy items, but also solves the problem that the bag body is prone to damage due to the downward pressure of the items when the items are heavy or the paper bag has been used for a long time. It also solves the problems of insufficient strength of the handle and insufficient strength of the inner wall of the paper bag.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
