Description

CONTAINER BAG HAVING UNITS INCLUDING CORNER SPACE PORTION

The present invention relates to a container bag. Specifically, it relates to a container bag having a body portion provided with units including an edge space portion.

A flexible intermediate bulk container (FIBC) was mainly used for transporting or storing unpackaged items in the form of bulk goods.

In the production of such a container bag, the prior art, as shown in Figure 2, the corner space was formed by combining three fabrics, that is, two inner wall members 20 and one support member 60.

In particular, when analyzing the corner space (C), as shown in Figs. 3 and 4, the independent upper wall member (20-post) and the right wall member (20-right) and independent support member, respectively. It was manufactured in such a way as to individually combine with (60).

In this manufacturing method, the number of sewing cycles decreases productivity, and the outer surface of the edge space is a sewing combination of two fabrics, so that it is exposed to the risk of damage to the sewing area due to the expansion of the contents. Since the dogs are all sewn in one sewing machine (sewing machine), various problems have been raised, such as the need for a lot of work space, the weak strength of the sewing part, and the leakage of contents through the sewing part.

Korean Registered Patent Publication No. 10-1032147 is a prior art for improving the strength vulnerability of the sewing part among various problems. However, as shown in FIG. 5, two side fabrics 20 are still disposed at a substantially right angle, and the fabric fabric 60 is disposed therebetween and then sewn.

However, even in the case of such a sewing method, there are vulnerabilities that the above-mentioned problems are still not improved.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily practice. As those of ordinary skill in the art to which the present invention pertains can readily understand, the embodiments described below may be modified in various forms without departing from the concept and scope of the present invention. Where possible, the same or similar parts are indicated by the same reference numerals in the drawings.

The terminology used in this specification is only for referring to specific embodiments, and is not intended to limit the present invention. The singular forms used herein also include plural forms unless the phrases clearly indicate the opposite.

As used herein, the meaning of “comprising” embodies certain properties, regions, integers, steps, actions, elements and / or components, and other specific properties, regions, integers, steps, actions, elements, components and / or It does not exclude the presence or addition of military forces.

All terms including technical terms and scientific terms used in the present specification have the same meaning as those generally understood by those skilled in the art to which the present invention pertains. The terms defined in the dictionary are further interpreted as having meanings consistent with the related technical literature and the presently disclosed contents, and are not interpreted in an ideal or very formal meaning unless defined.

The upper / lower, inner / outer side used in this specification may be understood based on the presented drawings. Also, the drawings may be exaggerated to show features of the invention.

Hereinafter, the present invention will be described with reference to the drawings. The container bag according to the present invention is also common to the prior art in that it is a method of combining several fabrics. However, the present invention is differentiated in the technical configuration as to which fabrics are combined with each other, and in what constructions each fabric is combined to form a body portion.

In this specification, in order to more clearly describe the technical features of the present invention, the technical features of the present invention will be described with reference to a cross-sectional view of a portion in which the container bag is cut in the transverse direction.

2 is an exploded perspective view showing a conventional container bag manufacturing method, and shows a double structure in which the outer structure is further provided outside the inner structure. 3A and 3B are schematic views for explaining a coupling method of an internal structure excluding an external structure among the internal structures of FIG. 2. 4 is a view for explaining a conventional method of manufacturing a container bag, and is a schematic view of a cross-section of a cut.

In the prior art and the present invention, the inner structure such as the corner space portion structure of the container bag is provided in common. In the prior art, as shown in FIGS. 3A and 3B, the side wall member 20-right disposed on the rear side and the side wall member 20-right disposed on the right side, and the support member 60 disposed between both side wall members As each is combined, an edge space portion C is formed.

Analyzing the prior art, it can be seen that the outer surface of the edge space portion is not a single fabric, but two fabrics, that is, two sidewall members are sewn. In addition, it can be seen that the parts to be sewn are two overlapping parts. Furthermore, it can be seen that the sewing part is formed simultaneously on the inside and the outside of the container bag.

It has been described above that the characteristics of the prior art can cause various problems. More specifically, it is as follows. First, when two sidewall members are sewn on the outer surface of the corner space, there is a possibility that the sewn part is damaged by the expansion of the contents, and in this case, the middle part of the edge having the sewn part is vulnerable to damage.

Second, since the sewing unit overlaps the two fabrics, there is a problem in that it is vulnerable to load even after the engaging portion is sewn. However, the stiffness may be reinforced by folding and sewing the joining fabric.

Third, since the sewing part is formed on the inside and the outside of the container bag at the same time, there is a problem that foreign matter, moisture, and the inner receiving material are moved to the sewing thread hole.

Fourth, as the sewing thread comes off, there is a problem that it is mixed into the inner receiving material.

However, the container bag according to the present invention uses one identical fabric to form the outer periphery of the corner space. Therefore, a sewing portion is unnecessary on the outer periphery of the corner space portion. In addition, after manufacturing the unit including the edge space in advance, there is an advantage of forming the body portion only by post-joining these units. Of course, it is possible to produce simultaneously, not pre-production.

This means that a wide working space required for the production of a conventional container bag is unnecessary, and it also means that the manufacturing process of the container bag, which has been carried out as a single process at the same time, can be performed as a division process for each unit.

Furthermore, the actual number of sewing is also reduced. In the case of the prior art shown in FIG. 4, there are 12 sewing parts (engaging parts), whereas in the embodiment shown in FIG. 5, there are only 8 sewing parts (engaging parts). The number of sewing of the present invention is reduced by 1/3 compared to the prior art. Of course, in the embodiment according to FIG. 11 of the present invention, there are also 12 sewing times.

However, in the case of the present invention, since it can be separately produced in advance in units, the number of sewing in the process of manufacturing the actual finished product may be substantially reduced.

That is, since the number of times of sewing is reduced, division of labor is possible, and separate production of units is possible, the technical configuration of the present invention that enables such a point can be regarded as clearly different from that of the prior art.

The body part according to the present invention may be provided in a polyhedron shape by connecting a plurality of units. In the present specification and drawings, the present invention will be mainly described with reference to an embodiment in which four units are connected and provided in a rectangular parallelepiped or a regular cube shape.

On the other hand, as shown in Figure 6, when explaining the features of the invention, it is appropriate to describe the cross-sectional shape of the container bag as a square (FIG. 6A), and when the contents are received inside the manufactured container bag, the cross-section of the container bag The shape, in particular the transverse cross-sectional shape of the body portion, may be described as a rough circle (Fig. 6B).

Figure 5 is for explaining the configuration of the container bag according to the present invention, a schematic view of the cross-section of the cut.

After the unit 5 is prepared, the corner member 110 and the partition member 120 of the unit 5 and the side wall member 130 of the other unit or the individual side wall member 130 at each coupling portion S at both ends of the unit 5 Can be combined together.

Hereinafter, the structure and the coupling method of the coupling portion S according to the present invention will be described.

Of course, various methods may be applied to the method of being combined at each coupling portion of each unit. However, since a combination of sewing is frequently used in a container bag, hereinafter, the description will be focused on the sewing combination.

When sewing is combined, it is possible that the filler cord is sewn together. The filler cord is sewn together with a sewing thread. The filler cord can be used to fill the needle hole, which is a sewing hole, to make it waterproof, prevent pollutants from entering, and strengthen strength.

However, among the embodiments of the present invention, when the embodiment of folding the end is applied, the outflow of the contents is blocked by the folded coupling structure, and the inflow of foreign matter is also blocked, so a filler cord may be unnecessary.

On the other hand, since the folded coupling structure is thicker than the surroundings, the strength increases in proportion to the number of folding. Therefore, the conventional container bag does not bear the load of the contents, and the sewing part is often damaged, but the folded joint structure according to the present invention can secure the strength enough to withstand the load of the contents.

One side wall member 130 and the other side wall member 130 may be coupled to the coupling part of the coupling part S. 8A to 8D are various embodiments of a coupling structure between side wall members according to the present invention, and are schematic views of a cross section of a cut portion. 8A shows an embodiment in which two sidewall members are sewn and coupled in an overlapped state. 8B to 8D show an embodiment in which the overlapped portion is folded and then sewn.
