[0002] The full name of the container bag is flexible container bag, also known as big bag, ton packaging bag, which is a soft and bendable packaging container. It is a large-volume transport bag made of foldable rubberized cloth, resin-processed cloth and other soft materials. Generally, it is made of polypropylene or polyethylene as the main raw material, extruded into film, cut, wired, and then woven, cut and sewn. The use of this kind of packaging is not only conducive to improving loading and unloading efficiency, but also particularly suitable for the packaging of bulk powder and granular goods, which is conducive to promoting the standardization and serialization of bulk cargo packaging and reducing transportation costs. It also has the advantages of easy packaging, storage and low cost. It is particularly suitable for mechanized operations and is an ideal choice for warehousing, packaging and transportation. It can be widely used in the packaging of bulk materials such as cement, fertilizer, salt, sugar, chemical raw materials, and ore for road, rail and sea transportation. Therefore, in recent years, countries around the world have widely used container bags to transport powder and granular goods. The emergence and use of container bags is a qualitative revolution in the way of shipping powder and granular goods.

[0003] However, the current flexible container bags can only be shaped when they are filled with materials, which causes the bag body to collapse easily when the materials are put in, thus requiring manual support. In addition, the existing container bags are stacked together in an irregular shape after use, which makes it cumbersome, time-consuming and laborious for users to store the container bags, and it is inconvenient for users to store the container bags.

[0004] Therefore, it is necessary to provide a new three-dimensional structure container bag to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a three-dimensional structure container bag.

[0006] The three-dimensional structure container bag provided by the utility model comprises a bag body, wherein the waist section of the bag body is provided with an elastic pleated portion, and a plurality of annular plates equidistantly distributed up and down are fixedly embedded on the elastic pleated portion;

[0008] Each of the annular plates is provided with a plurality of annularly distributed insertion holes, an anti-expansion rod is inserted into the annular plate with the insertion holes coaxially arranged on the bag body, and threaded heads are fixedly engaged at both ends of the anti-expansion rod.

[0009] Preferably, the rubber ball corresponds to the hemispherical groove one by one and has an interference fit.

[0010] Preferably, an upper ring plate is provided on the outer ring bag surface near the top of the bag body, a circle of elastic connecting cloth is fixedly embedded in the inner ring wall of the upper ring plate, and the elastic connecting cloth is fixedly sewn to the outer ring bag surface of the bag body, a plurality of annularly distributed threaded through holes are opened on the upper ring plate, and a threaded barrel with a threaded connection is inserted in each of the threaded through holes, and the inner and outer cylinder walls of the threaded barrel are both provided with threads.

[0011] Preferably, a lower ring plate is provided on the outer ring bag surface of the bag body close to the bottom, and a plurality of threaded holes distributed in an annular manner are opened on the lower ring plate.

[0012] Preferably, the threaded barrel of the upper ring plate, the insertion hole opened on the annular plate and the threaded hole opened on the lower ring plate correspond to each other one by one.

[0013] Preferably, a bag opening is provided at the top of the bag body, and a tightening rope is connected in series to the bag opening.

[0014] Compared with the related art, the three-dimensional structure container bag provided by the utility model has the following beneficial effects:

[0015] 1. The utility model has an elastic pleated part on the bag body, so when the container bag is not in use, the elastic pleated part can be used to shrink the pleats, and at the same time, the rubber ball on the annular plate is clamped into the hemispherical groove of the lower annular plate, so that the shrunk container bag can be locked to prevent the container bag from stretching at will;

[0016] 2. The utility model passes one end of the anti-expansion rod through the insertion hole formed in the uppermost annular plate, and then sequentially passes through the corresponding insertion holes of the lower annular plate, and then screws the threaded head thereof into the corresponding threaded hole on the lower annular plate. After installing a plurality of anti-expansion rods, the upper annular plate is flipped over with an elastic connecting cloth so that the threaded barrel corresponds to the threaded head at the top of the anti-expansion rod, and then the threaded barrel is rotated so that the threaded barrel is threadedly fixedly connected to the threaded head at the top of the anti-expansion rod, thereby enhancing the supporting strength of the bag body, and also facilitating the shaping of the bag body, which is convenient for subsequent stacking. At the same time, the anti-expansion rod cooperates with the annular plate to further avoid the hidden danger of damage to the bag body due to expansion of the bag caused by excessive storage of materials.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figures 1 to 6 An embodiment of the utility model provides a three-dimensional structure container bag, which includes: a bag body 1, an elastic pleated portion 11, an annular plate 2 and an anti-expansion rod 5.

[0027] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The waist section of the bag body 1 is provided with an elastic pleated portion 11, and a plurality of annular plates 2 equidistantly distributed up and down are fixedly embedded on the elastic pleated portion 11, and the upper plate wall of each annular plate 2 is provided with a plurality of annularly distributed hemispherical grooves 2a, and the lower plate wall of each annular plate 2 is fixedly embedded with a plurality of annularly distributed rubber balls 21, and the rubber balls 21 correspond to the hemispherical grooves 2a one by one and are interference fit.

[0028] It should be noted that: since the bag body 1 is provided with an elastic pleated portion 11, when the container bag is not in use, the elastic pleated portion 11 can be used to pleat and shrink, and at the same time, the rubber ball 21 on the annular plate 2 is engaged with the hemispherical groove 2a provided on the lower annular plate 2, so that the shrunk container bag can be locked to prevent the container bag from stretching at will;

[0029] When the bag body 1 is used, the adjacent annular plates 2 are pulled apart and then the elastic pleated portion 11 is stretched. The annular plates 2 arranged on the elastic pleated portion 11 can effectively avoid the hidden danger of the elastic pleated portion 11 being expanded by the material and causing partial damage to the container bag.

[0030] In the embodiments of the present invention, please refer to Figure 1 , Figure 5 and Figure 6 , an anti-expansion rod 5 is inserted on the annular plate 2 with an insertion hole 2b coaxially arranged on the bag body 1, and both ends of the anti-expansion rod 5 are fixedly embedded with a threaded head 51, an upper ring plate 3 is arranged on the outer ring bag surface of the bag body 1 near the top, and a circle of elastic connecting cloth 31 is fixedly embedded on the inner ring wall of the upper ring plate 3, and the elastic connecting cloth 31 is fixedly sewn to the outer ring bag surface of the bag body 1, a plurality of annularly distributed threaded through holes 3a are opened on the upper ring plate 3, and a threaded tube 32 connected by thread is inserted in each of the threaded through holes 3a, and the inner and outer tube walls of the threaded tube 32 are both provided with threads, a lower ring plate 4 is arranged on the outer ring bag surface of the bag body 1 near the bottom, and a plurality of annularly distributed threaded holes 4a are opened on the lower ring plate 4, and the threaded tube 32 of the upper ring plate 3, the insertion hole 2b opened on the annular plate 2 and the threaded hole 4a opened on the lower ring plate 4 correspond to each other.

[0031] It should be noted that: when the adjacent annular plates 2 are pulled apart and the elastic pleated portion 11 is stretched, one end of the anti-expansion rod 5 is passed through the insertion hole 2b opened in the uppermost annular plate 2, and then sequentially passes through the corresponding insertion hole 2b of the lower annular plate 2, and then the threaded head 51 is screwed into the corresponding threaded hole 4a on the lower annular plate 4. After the plurality of anti-expansion rods 5 are installed, the upper annular plate 3 is flipped over with the elastic connecting cloth 31 so that the threaded barrel 32 corresponds to the threaded head 51 at the top of the anti-expansion rod 5, and then the threaded barrel 32 is rotated so that the threaded barrel 32 is threadedly fixedly connected to the threaded head 51 at the top of the anti-expansion rod 5, thereby enhancing the supporting strength of the bag body 1, and also facilitating the shaping of the bag body 1, which is convenient for subsequent stacking. At the same time, the anti-expansion rod 5 cooperates with the annular plate 2 to further avoid the hidden danger of damage to the bag body 1 due to excessive storage of materials, resulting in partial bag body 1 expansion.

[0032] The top of the bag body 1 is provided with a bag opening 6, and a tightening rope 61 is serially connected to the bag opening 6. The ends of the tightening rope 61 are pulled respectively to shrink and seal the bag opening 6.

[0033] The working principle of the three-dimensional structure container bag provided by the utility model is as follows:

[0034] Since the bag body 1 is provided with an elastic pleated portion 11, when the container bag is not in use, the elastic pleated portion 11 can be used to pleat and shrink, and at the same time, the rubber ball 21 on the annular plate 2 is engaged with the hemispherical groove 2a provided on the lower annular plate 2, so that the shrunk container bag can be locked to prevent the container bag from stretching at will;

[0035] When the bag body 1 is in use, the adjacent annular plates 2 are pulled apart and then the elastic pleated portion 11 is stretched. At this time, one end of the anti-expansion rod 5 is passed through the insertion hole 2b opened in the uppermost annular plate 2, and then the corresponding insertion hole 2b of the lower annular plate 2 is passed in turn, and then the threaded head 51 is screwed into the corresponding threaded hole 4a on the lower annular plate 4. After installing multiple anti-expansion rods 5 respectively, the upper annular plate 3 is flipped over with the elastic connecting cloth 31 so that the threaded tube 32 corresponds to the threaded head 51 at the top of the anti-expansion rod 5, and then the threaded tube 32 is rotated so that the threaded tube 32 is threadedly fixedly connected with the threaded head 51 at the top of the anti-expansion rod 5, thereby enhancing the supporting strength of the bag body 1 and facilitating the shaping of the bag body 1, thereby facilitating the putting of materials into the bag body 1 and the subsequent stacking of the bag body 1. At the same time, the anti-expansion rod 5 cooperates with the annular plate 2 to further avoid the hidden danger of damage to the bag body 1 due to excessive storage of materials and the expansion of the bag 1.
