Description

Technical Field

[0001] This utility model relates to the field of container bag technology, and in particular to a container bag with good sealing effect. Background Technology

[0002] FIBCs are flexible transport packaging containers, mainly used for loading and transporting bulk materials. They are generally made of high-strength woven materials such as polypropylene, and can withstand a weight of several hundred kilograms to several tons. They can also be folded and stored, saving space when empty. Currently, the most common methods for sealing the opening of FIBCs (Flexible Intermediate Bulk Containers) are rope tightening and fastening, which involves threading a rope through a hole at the edge of the bag opening, tightening it, tying a knot, and sewing. The bag opening is then sewn shut with needle and thread and the edges are locked. However, rope tightening leaves gaps, and the weight of the material can further widen the opening. The needle holes in the sewn seal create natural seepage channels, allowing moisture and external liquids to easily seep into the bag. This can cause the material inside the FIBC to mold and clump, rendering it unusable. At the same time, moisture increases the weight of the bag, increasing the risk of breakage, and can also cause the material to stick to the bag wall, resulting in waste during unloading. Utility Model Content

[0003] The purpose of this utility model is to provide a container bag with good sealing effect, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A container bag with good sealing effect includes a bag body, several lifting straps fixedly connected to the outside of the bag body, double warp fabric fixedly connected to the outside of the bag body, a bag opening fixedly connected to the bag body, a binding sleeve movably connected to the bag opening, a binding rope inserted through the outside of the binding sleeve, a pre-tightening wire inserted through the binding sleeve, the bag body and the bag opening each include an outer protective layer, a waterproof membrane is provided on the inner side of the outer protective layer through an adhesive layer, and an anti-stick inner layer is provided on the inner side of the waterproof membrane.

[0005] As a further optimization of this utility model, the double warp fabric is sewn onto the outside of the bag body and covers the outside of several straps, thereby improving the tensile and tear resistance of the bag body.

[0006] As a further optimization of this utility model, the pre-tightening wire is made of metal. When the binding sleeve is put onto the bag opening, the pre-tightening wire can be squeezed to deform the wire and tighten the bag opening at the bottom of the binding sleeve, thus pre-fixing the bag opening. This makes it easier to continue to tighten the binding sleeve with the binding rope to bind the bag opening, thereby achieving the function of binding the bag opening and waterproof sealing.

[0007] As a further optimization of this utility model, the outer protective layer is made of polypropylene woven fabric, which gives the bag body and bag opening wear-resistant and puncture-resistant properties, and forms the main body of the bag body and bag opening.

[0008] As a further optimization of this utility model, the adhesive layer is a roller-coated adhesive layer, which realizes the connection between the waterproof membrane and the outer protective layer and eliminates the gaps between the layers. The waterproof membrane is a low-density polyethylene film, which improves the waterproof and sealing performance of the outer protective layer and blocks the penetration of external water vapor and liquid.

[0009] As a further optimization of this utility model, the anti-stick inner layer is a modified polypropylene film, which can prevent the material inside the bag from sticking to the waterproof membrane.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a binding sleeve is provided at the bag opening. The binding sleeve works in conjunction with a metal pre-tightening wire and a binding rope. First, the binding sleeve is initially tightened at the bag opening by squeezing the pre-tightening wire, and then the binding rope is used to further tighten it. Compared with traditional rope fastening and sewing sealing, this significantly improves the sealing performance of the bag opening and effectively prevents external moisture and liquid from seeping in. At the same time, the bag body and bag opening adopt a multi-layer structure of outer protective layer, adhesive layer, waterproof membrane, and non-stick inner layer. The outer protective layer of polypropylene woven fabric ensures wear resistance and puncture resistance, and the waterproof membrane inside strengthens the waterproof seal. The modified polypropylene non-stick inner layer prevents materials from sticking together and facilitates unloading. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-3As shown, the present invention provides a container bag with good sealing effect, including a bag body 1, a plurality of lifting straps 2 fixedly connected to the outside of the bag body 1, a double warp cloth 3 fixedly connected to the outside of the bag body 1, a bag opening 4 fixedly connected to the bag body 1, a binding sleeve 5 movably connected to the bag opening 4, a binding rope 6 inserted through the outside of the binding sleeve 5, a pre-tightening wire 7 inserted through the binding sleeve 5, the bag body 1 and the bag opening 4 also include an outer protective layer 8, a waterproof membrane 9 is provided on the inner side of the outer protective layer 8 through an adhesive layer 10, and an anti-stick inner layer 11 is provided on the inner side of the waterproof membrane 9.

[0015] like Figure 1 As shown, double-warp fabric 3 is sewn onto the outside of the bag body 1 and covers the outside of several straps 2, thereby improving the tensile and tear resistance of the bag body 1.

[0016] like Figure 2 As shown, the pre-tightening wire 7 is made of metal. When the binding sleeve 5 is put onto the bag opening 4, the pre-tightening wire 7 can be squeezed to deform the pre-tightening wire 7, thereby tightening the bag opening 4 at the lower part of the binding sleeve 5. This serves to pre-fix the bag opening 4, making it easier to continue to tighten the binding sleeve 5 with the binding rope 6 to bind the bag opening 4, thus realizing the function of binding the bag opening 4 and waterproof sealing of the binding sleeve 5.

[0017] like Figure 3 As shown, the outer protective layer 8 is made of polypropylene woven fabric, which gives the bag body 1 and the bag opening 4 wear-resistant and puncture-resistant properties, and forms the main body of the bag body 1 and the bag opening 4. The adhesive layer 10 is a roller-coated adhesive layer, which realizes the connection between the waterproof membrane 9 and the outer protective layer 8 and eliminates the gaps between the layers. The waterproof membrane 9 is a low-density polyethylene film, which improves the waterproof and sealing performance of the outer protective layer 8 and blocks the penetration of external water vapor and liquid. The anti-stick inner layer 11 is a modified polypropylene film, which can prevent the material inside the bag body 1 from sticking to the waterproof membrane 9.

[0018] It should be noted that this utility model is a container bag with good sealing effect. When sealing, the bag opening 4 is tightened and the binding sleeve 5 is placed on the outside of the bag opening 4. Then, the pre-tightening wire 7 is squeezed by external force, causing the pre-tightening wire 7 to deform. The deformed pre-tightening wire 7 will cause the area below the binding sleeve 5 to contract, thereby initially tightening the bag opening 4 and achieving pre-fixation of the bag opening 4. Subsequently, the binding rope 6 inserted on the outside of the binding sleeve 5 is pulled manually. By tightening the binding rope 6, the inner diameter of the binding sleeve 5 is further reduced, allowing the binding sleeve 5 to fit tightly against the outside of the bag opening 4, forming a secondary seal. Thus, the binding sleeve 5 wraps and fixes the opening of the bag opening 4, preventing external moisture and liquid from seeping in. Furthermore, in conjunction with the multi-layered structure of the bag body 1 and the bag opening 4, the outer protective layer 8 is made of polypropylene woven fabric, which can resist abrasion and puncture during handling and protect the internal structure. The adhesive layer 10 on the inner side of the outer protective layer 8 is a roller-coated adhesive layer, which can tightly connect the outer protective layer 8 and the waterproof membrane 9, eliminate gaps between layers, and prevent moisture from seeping in from between layers. In addition, the waterproof membrane 9 is a low-density polyethylene film, which can further block external moisture and liquids to ensure that the inside of the bag is dry. The anti-stick inner layer 11 on the inner side of the waterproof membrane 9 is a modified polypropylene film, which can prevent the material inside the bag from sticking to the surface of the waterproof membrane 9. During subsequent unloading, the material can be discharged smoothly, reducing residue and waste.
