Description

Container bag having swell preventing function}

It relates to a container bag, and more particularly, to a container bag having a function of preventing a fullness phenomenon occurring when the container bag is full of cargo.

In general, a container bag is widely used for loading and transporting various products such as chemical products (powder or powder), grain, grain flour, feed, fertilizer, stone, soil, cement, and the like. In particular, in recent years, a container bag has been widely used in order to transport large-capacity bulk products, ie, products in the form of beads, granules, pellets, flakes, and the like by using ships or vehicles.

In addition, the container bag loads a cargo weighing several hundred kilograms (kg) to several tons (ton), and is usually made of a fabric made of synthetic resin (PP, PE, etc.) as a raw material. Container bags are manufactured in various forms depending on the type, use, and purpose of the cargo, and have a special material, shape, and structure for receiving, discharging, and transporting the cargo.

In addition, the overall shape of the container bag is roughly divided into a rectangular parallelepiped type and a cylindrical type depending on the intended use. In addition, it may have a cargo inlet at an upper portion of the container bag for receiving and discharging cargo, and a cargo outlet at a lower portion thereof. In some cases, a single inlet and outlet is provided on the upper side of the container bag, and cargo is injected and discharged through the inlet and outlet.

In addition, a handle may be provided on the top or side of the container bag to unload or transport the container bag to a short distance. The handle is roughly divided into a rope-type and a belt-type depending on the shape, and a form in which some of the belts (or ropes) attached to the container bag are connected to each other using a rope (or belts) may be used. The container bag is also called various names such as a sack, a bulk bag, a bulk container, a jumbo bag, and a flexible intermediate bulk container (FIBC).

Looking at a conventional example, the container bag 100, as shown in FIG. 1, is made of a rectangular parallelepiped body, and the body has four side parts 110a, 110b, 110c, 110d and an upper surface part ( 112) and a lower surface portion 114. A cargo inlet 120 for injecting cargo into the body is provided on the upper surface 112 , and a tightening line 121 for closing the opening is provided on the cargo inlet 120 . A tightening strap or other opening closing structure may be provided separately from or together with the tightening line 121 .

Similar to the upper surface portion 112, the lower portion 114 is provided with a cargo outlet 130 for discharging cargo from the main body, and the cargo outlet 130 has a tightening line 131 for closing the opening. this is provided A tightening strap or other opening closing structure may be provided separately from or together with the tightening line 131 . Among the four side parts 110a, 110b, 110c, and 110d, the upper surfaces of the adjacent side parts 110a, 110b, 110c, and 110d have a handle 140 for loading and unloading and transporting the container bag 100 . ) is provided.

When cargo, in particular, cargo in powder or powder form is loaded in the container bag 100 , a high pressure is applied to the center of the side portion, resulting in a fullness phenomenon in which the side portion of the container bag 100 bulges. This satiety phenomenon is an obstacle to densely loading the container bag 100 in a limited space, and also the side portions of the loaded container bag 100 excessively contact each other, so that the container bag 100 during long-term transportation ( 100) is also damaged by friction with each other. In addition, when the container bag 100 is loaded in multiple layers, it may fall or slide to either side.

As shown in FIG. 2 , in order to prevent such a full stomach phenomenon, a baffle 150 may be provided inside the side portions 110a and 110b adjacent to each other of the container bag 100 . The baffle 150 prevents the side portions from bulging by connecting and supporting the central portions of the side portions 110a and 110b adjacent to each other. A total of four baffles 150 may be provided inside the container bag 100 having a rectangular parallelepiped shape. Openings 151 of various shapes are provided in the baffle 150 so that powder or powdered cargo can flow. Both end portions 152 and 153 of the baffle 150 may be coupled to the inner side of the side portions 110a and 110b with a bar yarn 160 .

By providing the baffle 150 inside the container bag 100 , the fullness phenomenon can be reduced, but the following problems occur when loading cargo. As shown in FIG. 3, when the cargo P in the form of granules such as powder/powder is loaded from the upper side of the container bag 100, the cargo P is accumulated in the lower central part due to the slip property of the granules, and the inclined surface The cargo (P) flows down to the periphery along There is a problem with this not loading well.

In addition, due to this, there is a possibility that the container bag 100 at the upper end of the container bag 100 may collapse due to loss of balance during the two-layer stacking necessary for transporting the container bag 100 filled with cargo or loading and unloading the container bag 100 . In addition, this problem is particularly pronounced in the portion other than the opening 151 of the baffle 150, and also has a problem of interfering with the smooth discharge of the cargo due to the baffle 150. Republic of Korea Patent No. 10-1586610 "a container bag provided with a net-shaped corner bulkhead" proposes a container bag provided with a corner bulkhead disposed at each inner corner in order to solve this problem.

Hereinafter, a container bag having such an anti-full function may be briefly referred to as a “container bag”.

4 is a perspective view of a container bag according to an embodiment of the present invention. The container bag according to this embodiment, like the conventional container bag shown in FIG. 1 , has a rectangular parallelepiped shape consisting of four side wall parts 1 , a bottom part, and a cover part so that cargo in powder or powder form can be loaded therein. is formed with The container bag of this embodiment includes a corner partition wall portion 10 disposed at a corner between two adjacent side wall portions 1, and the feature of this embodiment lies in the corner partition wall portion 10. Accordingly, the container bag in a state in which the cover part is omitted is shown in FIG. 4 so that the edge partition wall part 10 can be exposed. Corner partition wall portions 10 are disposed at each corner between two adjacent side wall portions 1 of the container bag. That is, the container bag includes a total of four corner partition walls 10 .

5 is a partially enlarged view of the corner partition wall portion 10 shown in FIG. 4 , and FIG. 6 is a real photograph of the corner partition wall portion 10 illustrated in FIG. 4 . Since it is difficult to understand the weaving structure of the corner partition wall portion 10 only with the actual photograph shown in FIG. 6 , the thickness of the yarn woven according to this embodiment is omitted and the thickness is expressed as a line, and the spacing of the yarns in contact with each other is enlarged and shown in FIG. 5 . Referring to FIGS. 4 to 6 , the corner partition wall portion 10 includes a first net portion 110 and a second net portion 110 . 6 is a photograph of only the first net unit 110 so that the first net unit 110 can be shown in detail.

The first net part 110 and the second net part 110 may be fixed to the two adjacent side wall parts 1 in various ways such as an adhesive method and a sewing method, but in the case of a polypropylene material, a sewing method is preferable. do. Since such a fixing method is not related to the characteristics of the present embodiment, a detailed illustration of the fixing method is omitted.

Accordingly, a portion of the first weft yarn 112 of the first net portion 110 is extended to the second net portion 110 , and the first weft yarn is between the first net portion 110 and the second net portion 110 . (112) is over. The portion of the first weft yarn 112 that spans between the first net portion 110 and the second net portion 110 maintains a constant interval between the two adjacent sidewall portions 1 when the container bag is filled with cargo. plays a role in keeping That is, the portion of the first weft yarn 112 that spans between the first net portion 110 and the second net portion 110 has a gap between the two adjacent sidewall portions 1 as the container bag is filled with cargo. It serves to prevent bloating. The corner partition wall portion 10 is preferably made of a non-stretchable material such as polypropylene.

In this embodiment, since only two weft yarns are required for the manufacture of the corner bulkhead part 10, simultaneous weaving of the first net part 110 and the second net part 110 is possible, so the corner bulkhead part according to this embodiment (10) can be made by a single weaving process. In this way, as it can be manufactured by a single weaving process, a container bag having an anti-satisfaction function can be manufactured at a low cost within a short time. In particular, since operator intervention can be minimized in the container bag manufacturing process, errors in the manufacturing process due to operator error can be minimized.

Republic of Korea Patent No. 10-1586610 "Container bag provided with a net-shaped corner bulkhead" presents a container bag provided with corner bulkheads disposed at each inner corner. In this prior art, since three weft yarns are required for the manufacture of the corner partition wall part or the support member must be manufactured first, the edge partition wall part cannot be manufactured by a single weaving process, but is manufactured through several processes. Accordingly, in the prior art, compared to the present embodiment, manufacturing the corner partition wall portion is cumbersome and takes a long time, and there are many parts that require an operator to intervene between various processes, so there is a high possibility of errors in the manufacturing process due to operator error.

The reciprocating section of the first weft yarn 112 of the first net portion 110 consists of a short-distance reciprocating section 114 and a long-distance reciprocating section 116 that are alternately arranged in the vertical direction. The short-distance reciprocating section 114 of the first weft 112 of the first net portion 110 is in the transverse forward direction (the right side of FIG. 5 ) in which the first weft 112 corresponds to the horizontal direction toward the second net portion 110 side. direction) and intersect with the first warp yarn 130 of the plurality of strands of the first net portion 110 and then in the horizontal reverse direction corresponding to the reverse direction of the horizontal direction toward the second net portion 110 (left direction in FIG. 5 ) ) is a section that intersects with the first warp yarn 130 of the plurality of strands of the first net portion 110 while proceeding to.

The long-distance reciprocating section 116 of the first weft yarn 112 of the first net portion 110 is a plurality of first warp yarns 130 of the first net portion 110 while the first weft yarn 112 proceeds in the transverse forward direction. ) and the plurality of second warp yarns 130 of the second net portion 110 and the second warp yarns 130 and the first plurality of yarns of the second net portion 110 while proceeding in the reverse direction after crossing in turn. It is a section that intersects with the first warp yarn 130 of the plurality of strands of the net portion 110 in turn.

The reciprocating section of the second weft yarn 112 of the second net portion 110 consists only of the short-distance reciprocating section 114 arranged in the vertical direction. That is, the second weft yarn 112 of the second net portion 110 crosses the plurality of second warp yarns 130 of the second net portion 110 while proceeding in the transverse forward direction, and then proceeding in the transversely reverse direction. It proceeds while repeating the process of crossing the first warp yarn 130 of the plurality of strands of the net portion 110 . The first weft yarn 112 of the first net portion 110 is the second weft yarn 112 of the second net portion 110 in the long-distance reciprocating section 116, together with the second weft yarn 112 of the second net portion 110. 2 will intersect with the warp yarn (130).

In the embodiment shown in FIG. 5, the short-distance round-trip section 114 and the long-distance round-trip section 116 alternate with each other in the order in which one long-distance round-trip section 116 is arranged between two adjacent short-distance round-trip sections 114. are arranged vertically. In the real thing shown in FIG. 6, the short-distance round-trip section 114 and the long-distance round-trip section 116 are alternately vertical in the order in which one long-distance round-trip section 116 is arranged after the seven short-distance round-trip sections 114 adjacent to each other. are listed in the direction In addition, the short-distance reciprocating section 114 and the long-distance reciprocating section 116 may be alternately arranged in the vertical direction in various arrangements.

As the long-distance reciprocating section 116 is arranged at a higher ratio with respect to the short-distance reciprocating section 114, the number of the first weft yarn 112 portions spanning between the first net portion 110 and the second net portion 110 increases. As the increase increases, the effect of preventing satiation of the container bag may be improved, but if the long-distance reciprocating section 116 is densely arranged, it may be impossible for the cargo in the form of large grains to pass through the corner bulkhead 10 . As the long-distance reciprocating section 116 is arranged at a higher and lower ratio with respect to the short-distance reciprocating section 114, the number of the first weft yarn 112 portions spanning between the first net portion 110 and the second net portion 110 Although the effect of preventing the satiation phenomenon of the container bag may be reduced as the decrease in , if the long-distance reciprocating section 116 is sparsely arranged, even the cargo in the form of large grains may easily pass through the corner bulkheads 10 . It is preferable that the ratio of the long-distance reciprocating section 116 to the short-distance reciprocating section 114 is appropriately designed in consideration of the fullness of the container bag and the particle size of the cargo powder.

Each long-distance reciprocating section 116 of the first weft yarn 112 includes a first warp yarn cross section 118, a first bulkhead reinforcement section 120, a second warp yarn cross section 118, and a third warp yarn cross section 118. , a second bulkhead reinforcement section 120 , and a fourth warp yarn crossing section 118 . The first warp yarn crossing section 118 is a section in which the first weft yarn 112 crosses the plurality of first warp yarns 130 of the first net portion 110 while proceeding in the transverse forward direction. In the first bulkhead reinforcement section 120, the first weft yarn 112 proceeds in the transverse forward direction by the interval between the first net portion 110 and the second net portion 110 following the first warp yarn crossing section 118. is the section The second warp yarn crossing section 118 crosses the plurality of second warp yarns 130 of the second net portion 110 while the first weft yarn 112 proceeds in the transverse forward direction following the first bulkhead reinforcement section 120 . is the section

The third warp crossing section 118 crosses the plurality of second warp threads 130 of the second net part 110 while the first weft thread 112 proceeds in the horizontal reverse direction following the second warp thread crossing section 118 . is the section In the second bulkhead reinforcement section 120, the first weft yarn 112 proceeds in the horizontal reverse direction by the interval between the first net portion 110 and the second net portion 110 following the third warp yarn crossing section 118. is the section In the fourth warp crossing section 118 , the first weft thread 112 crosses the plurality of first warp threads 130 of the first net part 110 while proceeding in the horizontal reverse direction following the second bulkhead reinforcement section 120 . is the section

Here, the first bulkhead reinforcing section 120 and the second bulkhead reinforcing section 120 correspond to the portion of the first weft yarn 112 spanning between the first net part 110 and the second net part 110 . . As shown in FIG. 4 , when the first net part 110 and the second net part 110 are attached to the two side wall parts 1 adjacent to each other, the first partition wall reinforcement section 120 and the second partition wall The reinforcement section 120 is bent at the boundary point between the first net part 110 and the second net part 110 and is diagonally disposed in the corner space of the container bag so that when the container bag is full of cargo, two neighboring parts are formed. It serves to prevent the phenomenon of satiation that spreads between the sidewalls (1).
