Description

Container bag {A container bag}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container bag, and more particularly, to a container bag having an improved structure so that a large number of container bags can be stacked in a predetermined space when the plurality of container bags are stacked and stored or transported.

In general, container bags are made of paper, fabric, or flexible synthetic resins, which are advantageous for light weight. They contain and store the contents of powder or small particles such as grain, feed, cement, synthetic resin, etc. Allow it to be transported.

Such a container bag can easily be deformed in appearance so that the container bag can be kept to a minimum volume without containing contents.

On the other hand, when transporting by air or ship, it is desirable to load a large amount of cargo in a predetermined space in order to reduce the logistics costs, such as the conventional container bag is the weight of the contents in the state containing the contents ( It is disadvantageous for space utilization because it protrudes outwardly by self weight.

Korean Utility Model Registration No. 0308347 discloses a container bag for preventing the side of the container bag from bulging convexly due to the weight of the contents.

As shown in Fig. 1, the container bag 1 is a woven fabric in which warp yarns and weft yarns are deviated from each other, and has a structure in which reinforcing portions 3 are formed by weaving edges and predetermined portions more densely than adjacent portions.

The container bag 1 has the advantage of preventing the bulging to the side by the resistance of the reinforcing part 3 even if the weight of the contents is formed by forming the reinforcing part 3 for each predetermined portion in the vertical direction However, since the reinforcement part 3 is formed long in the vertical direction, in the case where the container bag 1 itself has a large capacity, not only the filling phenomenon occurs even when the reinforcement part 3 is formed, but the reinforcement part 3 is adjacent to the reinforcement part 3. It may cause damage, such as tearing in the part.

That is, as shown in Figure 2, when the contents are biased to one side by inertial or centrifugal force during transportation, not only induces a concentrated load to cause the container bag to burst (torn), but also a large number of container bags in the loading space It will not load and will cause the loaded container bag to fall.

In the case of a container bag for maintaining a circular shape used in the related art, as shown in Fig. 6, the edge portion is joined to the edge space because the edge portion is continuously extended from the upper end point to the lower end point in the longitudinal direction, which is the input direction of the contents. It was very difficult to charge and was time consuming, so a lot of packaging could not be done at the time it was delivered.

When packaging hundreds of tons in limited facilities, the conventional round container container has a lot of inconveniences in terms of packaging speed and is a factor of cost increase.

The present invention has been made to solve the above problems, and to provide a container bag whose structure is improved to maintain the original shape of the receiving space as much as possible.

Another object of the present invention is to provide a container bag having an improved structure so that more cargo can be loaded in a limited space.

It is still another object of the present invention to provide a container bag that is improved to prevent damage such as tearing due to the load of the contents contained therein.

In addition, the present invention has a purpose to enable a large amount of packaging at a predetermined time by increasing the filling speed of the contents.

The present invention to achieve the above object is in a flexible container bag which is formed in the inlet for injecting the contents at the top, and storing and transporting the contents,

A plurality of reinforcements are fixed on the same plane along the inner circumference,

By connecting each of the reinforcing rods with a connection of any one of a rope, tape or band,

It is characterized in that the tension is applied in the transverse direction perpendicular to the input direction of the contents to maintain the appearance.

The container bag of the present invention is provided with a plurality of reinforcing rods and connecting rods at regular intervals along the feeding direction, the discharge port for discharging the contents on the opposite side of the inlet.

The present invention to achieve the above object is in a flexible container bag which is formed in the inlet for injecting the contents at the top, and storing and transporting the contents,

An inner container bag having a plurality of reinforcing bars fixed on the same plane along an inner circumference thereof and connecting each of the reinforcing bars with one of a rope, a tape, and a band;

And an outer container bag in which the inner container bag is accommodated.

Meanwhile, the container bag of the present invention can be produced in a polygonal columnar shape or a circular columnar shape.

According to the characteristics of the present invention, the container bag of the present invention is maintained by the tension of the reinforcing rod and connecting rod provided at regular intervals even if the contents are filled, so that the space can be efficiently used when stored in a certain space.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The container bag of the present invention is made of paper, woven fabric or flexible synthetic resin material, which is advantageous for light weight, and contains powder or small particle contents such as grains, feed, cement, synthetic resin, which are highly fluid. It can be stored and transported.

3A to 3C showing the container bag 10 according to the embodiment of the present invention, it is a quadrangular column shape, and an inlet 10a and an outlet 10b are formed to allow the contents to be introduced and discharged in the upper and lower portions thereof. At the top, a towing ring 18 is provided to tow the contents.

The container bag 10 of the embodiment of the present invention is formed in a quadrangular column shape so as to be stacked upon loading of cargo and advantageous to space utilization, and the circular shape of the rectangular column shape is deformed by the weight of the contents when the contents are filled. In other words, it has a structure that is improved so that the bulging phenomenon that protrudes in the transverse direction does not occur.

In addition, when the rigidity of the container bag rather than the volume, such as liquid, etc. is required, it can be made into a polygonal or circular column shape to increase durability.

To this end, a plurality of reinforcing bars 15 are fixed on the same plane along the inner circumference of the container bag 10, and each of the reinforcing bars 15 is a rope, a tape, or a band. By connecting to any one of the connecting rod (15a), the tension is imparted in the transverse direction perpendicular to the direction in which the contents of the contents are formed to maintain the appearance.

The reinforcing table 15 and the connecting table 15a are provided in plural at regular intervals along the input direction to divide the internal space into a plurality of unit spaces 11 to 13.

At this time, the interval between the upper and lower reinforcing bar 15 is preferably smaller than the width of the container bag 10 in the transverse direction, the interval of each layer may vary in size depending on the load of the contents and each of the unit space (11 ~ 13) The reinforcing bar 15 may be combined in various embodiments (FIGS. 5A to 5E), and the number of reinforcing bars may be attached in large quantities in consideration of specific gravity of the contents.

In this case, as shown in FIGS. 4A and 4B, the external force due to the weight of the contents is distributed to the unit spaces 11 to 13 to deform the shape of the shape by the tension of the reinforcing bar 15 and the connecting table 15a. Calling phenomenon) can be effectively prevented and the robustness can be improved.

As shown in FIG. 7, the reinforcing table 15 and the connecting table 15a of the container bag of the present invention have a smaller unit area and are separated into upper and lower portions, respectively. The charging speed can be faster.

In fact, when I filled the conventional round container container, when the contents entered about 2/3, the contents were filled up to the end of the slot, and the whole contents were shaken and the contents were pushed to the edge by hand to charge. It took about 5 minutes.

On the other hand, the container bag of the present invention can be charged while spreading evenly to the front portion of the lower layer, it can be seen that the charging time takes about 2 minutes.

Therefore, the container bag of the present invention can significantly shorten the charging time in the case of fine powder, coarse particle content, high viscosity content, etc., and thus can significantly improve the work efficiency.

As a result of testing the shape of the container bag of the present invention and the container holder for the conventional circular holding under the same conditions and the contents of 700 kg each, the container line of the conventional container bag has the side line 22 in the longitudinal direction as shown in FIG. While the container bag of the present invention is bent, the side line (22 'of FIG. 10) remains relatively upright, and thus, the overall shape of the container bag is more clearly squared, and the conventional container bag is a seam from the top to the bottom due to internal pressure. While (23) is opened as a whole, the container bag of the present invention has a phenomenon that only the both ends of the seam 23 'are opened.

In addition, when the container bag is lifted and put in place, the conventional container bag is drooped because the load is concentrated to the lower end, and the height of the drooping part 24 of FIG. 9 is 7 cm from the ground to the lower end line. In the present invention, the bag sag 24 'of FIG. 10 has an average of 4.5 cm.

This means that the risk of dropping the container bag of the present invention in multi-stage loading is lower than that of the conventional container bag, and the safety degree is increased accordingly.

On the other hand, the reinforcing bar 15 may be implemented in various forms as shown in Figure 5a to 5e. This embodiment is various embodiments in which each of the reinforcing bars 15 is fixed to some or all of the portions in the lateral cross direction of the container bag.

The container bag of the present invention can be manufactured with a belt or a band having a small unit area as shown in FIGS. 5A, 5B, 5C, 5D, and 5E, and the width of the belt or the band is 30 cm or less. Suitable and less than 3cm thick would be appropriate.

In the embodiment of the present invention, the reinforcing bar 15 can be folded when stored in the state without filling the contents as in the container bag 10 can be kept to a minimum volume.

In the state in which the contents are sequentially filled, the external force due to the weight of the contents acts on the container bags 10, but the container bags 10 are externally maintained by the tension of the respective reinforcing bars 15 and the unit space ( Since it is possible to suppress the flow of the contents between 11 and 13), it is possible to significantly prevent the filling of the container bag 10 due to the concentrated load of the contents.

On the other hand, referring to Figure 8 showing another embodiment of the container bag of the present invention, the container bag 10 'of this embodiment may be accommodated in a separate outer shell (outer container bag; 20) and used in this case, the traction ring 21 is employed in the outer shell 20. At this time, the container bag 10 'and the outer shell (outer container bag; 20) may be stitched together and manufactured integrally. Since other reference numerals have the same names and functions as the above embodiment, detailed description thereof will be omitted.

Needless to say, the present invention as described above is not limited to the above embodiment and can be practiced with many modifications without departing from the spirit and scope of the present application.

The present invention as described above has the following advantages.

First, by adopting a reinforcement bar having a tension force in the transverse direction at regular intervals on the inner surface of the container bag, it is possible to maintain the original shape of the receiving space to the maximum despite the load of the contents, thereby loading more cargo in a limited space To do it.

Second, by dividing the inner space of the container bag by a reinforcement table to prevent the concentrated load by the contents to prevent damage such as tearing by the load of the contents.

Third, since the unit area occupied by the reinforcing rod and the connecting rod, which is the internal structure of the container bag, the filling time of the contents can be drastically shortened, thereby improving work efficiency.
