Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container bag used as a container for transporting or storing a fluid such as a liquid.

[0002]

2. Description of the Related Art Metal containers and rigid reinforced plastic containers are used as containers used for transporting and storing fluids. Particularly when it is not necessary to transport the fluids in a fixed amount, Tank lorries are also used.

[0003]

In the case of the drum or the container made of reinforced plastic, transportation cost is high when it is collected and used repeatedly, and it is necessary to wash it each time it is used. There are many problems in terms of cost, such as necessity of sterilization treatment.

[0004] The present invention has been made in view of the above-mentioned circumstances, and the cost of transporting containers is not high when they are collected and used over and over again, and cleaning and sterilizing treatment is not required each time they are used. It is intended to provide a low-cost container bag for storing fluid.

[0005]

A container bag according to the present invention, which has been made to solve the above-mentioned problem, has a cylindrical shape having an opening at at least one end, and the content is obtained by sealing the opening. A bag body that directly wraps an object, an internal reinforcing body made of woven cloth that covers and reinforces the bag main body and maintains a lower limit of the position of the bag main body, and the entire container bag that holds the internal reinforcing body from the outside. A rigid cylindrical liner having a resilience and a self-supporting shape, a rigid upper lid and a lower lid for sealing the upper and lower openings of the cylindrical liner, and opening and closing means on at least one end And a woven cloth body covering the cylindrical liner and the upper and lower lids.

Examples of the material of the bag body include polyethylene and polypropylene. The tubular body formed by the bag body may be a bottomed tubular shape having an opening at only one end, or may be a tubular shape having both ends. It may be a tubular shape without a bottom having an opening (see FIG. 1). The material of the inner reinforcing member and the outer member is not limited, but a thick material such as nylon, polyester, or vinylon, preferably a strong and light material which is advantageous in terms of cost, for example, a flat yarn made of polypropylene or polyethylene resin is used. It is desirable to use an endless woven web or a plain woven web made of yarn. The exterior body may have a bottomed tubular shape provided with opening / closing means only at one end, or a bottomless tubular shape provided with opening / closing means at both ends.

Since the cylindrical liner needs to be in contact with the inner surface of the body of the exterior body to keep the container bag itself cylindrical, the cylindrical liner has a diameter slightly smaller than the cross-sectional diameter of the exterior body. It is sufficient if it has a shape and is self-supporting. When forming the cylindrical shape, it does not matter whether it is configured by a single endless cylindrical liner or by connecting a plate-shaped liner in a cylindrical shape, but damage to the bag body due to a sharp object sticking etc. In order to prevent this, it is preferable that the connection intervals of the respective liners, which are components of the cylindrical liner, be as tight as possible.

Although the material of the cylindrical liner is not particularly limited, it is desirable that the material is hardly broken or damaged by folding or the like and has a high shape restoring property. In particular,
A multi-layered sheet combining rigidity and resilience formed by bonding a cross sheet made of flat yarn between paper sheets called kraft paper and paperboard (see FIG. 7). ), And a multi-layer structure sheet (see FIG. 8) having both rigidity and resilience obtained by bonding a cross sheet made of flat yarn to at least one surface of a paper sheet. , Laminating and the like.

The strength of the cylindrical liner, that is, the self-sustainability, rigidity, resilience, etc. of the container bag provided with the cylindrical liner, depends on the cross-sheet used in the multilayer sheet used as the material of the cylindrical liner. In addition to adjusting the density, the basis weight of the paper sheet, the increase / decrease of the driving density of the yarn constituting the cross sheet, and the increase / decrease of the amount of resin in the laminating process, a single multilayer structure sheet can be rolled to form a cylindrical liner. In the case of the configuration, since the adjustment can be made by increasing or decreasing the number of times of roll winding or by increasing or decreasing the amount of the adhesive applied between each roll winding layer, it is possible to perform a precise design in which the strength is calculated in advance according to the application.

Further, by maintaining the lower limit of the position of the bag body above the lower lid by the internal reinforcing member, a buffer space can be provided between the internal reinforcing member and the lower lid. Can be prevented. Assuming that the buffer space is an internal reinforcing body made of the material, the height of the cylindrical liner is 3 to
By securing a height equivalent to about 8%, it seems that both the capacity and the impact resistance of the container bag can be satisfied. However, the shape of the bottom of the external reinforcing member after filling the contents differs depending on the diameter of the container bag, and the smaller the diameter, the smaller the amount of droop at the center of the bottom. Therefore, if the diameter of the container bag body is large, even if a buffer space is formed at the peripheral edge of the bottom portion of the internal reinforcement, there may be little buffer space at the center thereof. Even so, the presence of the buffer space has a great effect in preventing the bag body existing inside the cylindrical liner from being broken.

Further, as the opening / closing means, the remaining portion of the outer package not overlapping with the cylindrical liner is shorter than the radius of the cylindrical liner in the longitudinal direction of the cylindrical liner from the edge of the cylindrical liner. At a position separated by a distance, a plurality of hooks are attached at equal intervals, and by using means for securing the hooks with one or more connecting members so that the hooks are close to each other at the center of the cylindrical liner. In some cases, the remaining portion of the exterior body may be uniformly drawn to the center of the container bag from the periphery.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A container bag according to the present invention will be described below with reference to the drawings. FIG. 1 shows a bag main body 1 having a cylindrical shape having openings at both ends and directly enclosing the contents by closing both openings, and the bag main body 1.
Woven fabric internal reinforcement 2 that covers and reinforces and maintains the lower limit of the location of the bag body 1;
Rigid and lineable cylindrical liner 3 which has a restoring property and retains the entire shape of the container bag while holding the container from the outside.
An upper lid 4 and a lower lid 5 having rigidity for sealing the upper and lower openings of the cylindrical liner 3 and a cylindrical shape provided with an opening / closing means 6 at an upper end, and the cylindrical liner 3, the upper lid 4 and the lower This is a container bag constituted by a woven cloth body 7 covering the lid 5.

The bag body 1 is a polyethylene tube having both ends opened, and uses the binding band 14 as a sealing means for sealing both upper and lower openings. The material of the bag body 1 is appropriately changed according to the properties of the contents.

The exterior body 7 and the internal reinforcing body 2 are made of woven fabric, and both have a bottomed cylindrical shape with an open upper end and a closed lower end. A notch 15 necessary for inserting a hand in the operation of positioning the bag main body 1 at the center is provided. In the vicinity of the cut 15, in order to restrict the movement of the bag main body 1 inside the internal reinforcing body 2, A string (tape) 16 for fixing the vicinity of the sealing means of the bag body 1 is fixed.

The woven fabric constituting the exterior body 7 and the internal reinforcing body 2 is a cross sheet of flat yarn made of polypropylene resin or polyethylene resin,
If a web (preferably a tubular endless web) in which 0 denier flat yarn is hammered in at a rate of 14 to 15 yarns / inch is used as a container bag capable of storing about 1 ton of fluid. It can have enough strength to withstand.

On the other hand, the cylindrical liner 3 of the container bag prototyped to verify the strength of the container bag according to the present invention has a paper sheet 8 made of kraft paper or paperboard and a cross sheet 9 laminated in a sandwich shape between the paper sheets 8. It is made of a multi-layer structure sheet having both rigidity and resilience that has been subjected to adhesive processing. The multi-layer structure sheet is rolled into a cylindrical shape and its circumferential edge is fixed. The height of the cylindrical liner 3 is set sufficiently lower than the height (depth) of the exterior body 7, and the lower edge thereof is positioned with respect to the height direction of the cylindrical liner 3 in order to obtain autonomy. It is cut vertically. It is desirable that the cross sheet 9 serving as a core material of the cylindrical liner 3 be a raw material in which 1000 denier flat yarns are driven at a rate of 10 to 14 lines / inch each, and the paper sheet 8 has a weight of 120 g. It is desirable to employ a material of about 180 g / m 2 to 180 g / m 2. In the prototype container bag, a 1000 denier flat yarn was inserted between 8 paper sheets each having a basis weight of 120 g / m 2, and a cross sheet 9 was inserted at a rate of 12 lines / inch. Using a multi-layered sheet with a width of 1100 mm, which has been subjected to lamination bonding with an agent,
The multilayer liner sheet was rolled five times, and a cylindrical liner 3 polymerized and bonded was used.

In assembling the container bag, the bag body 1 is inserted into the internal reinforcing member 2 while blowing air into the inner space of the bag body 1 having a closed lower opening, and the vicinity of the cut 15 at the center of the bottom is provided. Is connected to the bag body in the vicinity of the sealing means. The inner reinforcement 2 to which the bag body 1 is attached in this manner forms a hook portion 17 that hangs on the upper portion of the cylindrical liner 3 by appropriately folding the upper edge outward, and the bottom portion of the inner reinforcement 2 A buffer space 1 having a height corresponding to about 5% of the height of the cylindrical liner 3
The cylindrical liner 3 is hooked so as to approach the upper end side so as to generate 0. The cylindrical liner 3 on which the bag body 1 and the inner reinforcing body 2 are mounted is set at a lower portion of the outer body 7 in which the lower lid 5 is previously loaded, and the container bag before the contents are filled. Is assembled.

The remaining portion 11 of the upper part of the exterior body 7 that does not overlap with the cylindrical liner 3 is
A plurality of hooks 12 are provided at equal intervals from the edge of the cylindrical liner 3 in the longitudinal direction of the cylindrical liner 3 at a distance shorter than the radius of the cylindrical liner 3. In addition to serving as opening / closing means 6 for covering and covering the upper lid 4 by pulling them closer to each other at the center of the opening of the cylindrical liner 3, a uniform force is applied to each part of the cylindrical liner 3 toward the center of the opening. And serves to maintain the upper edge in a state close to a perfect circle.

The hook 12 in the example shown in FIG.
The string is firmly sewn to the exterior body 7, and the string is also used as the connecting member 13 for drawing each string to each other. Any structure may be used as long as it can be used as a cue, and the connecting member 13 may have any structure as long as the engaging portion 12 can be pulled toward the center of the opening of the cylindrical liner 3. Also, the remaining part 11
5 (b), each part including the hooking portion 12 may be cut into a fan shape leaving a minimum necessary cloth, or as shown in FIG. 4 (b). Instead, the lower cylindrical shape may be maintained, and each hooking portion 12 may be drawn to form a portion that partially overlaps the remaining portion 11 on the upper lid 4.

The bag body 1 of the container bag is filled with the contents and hermetically sealed, the upper lid 4 is placed thereon, and the opening of the exterior body 7 is closed as described above (FIG. 4 (a) and FIG. 5 (a)) is a mode for transportation and storage. In the container bag filled with the contents, the pressure on the body of the bag body 1 is received by the body of the internal reinforcement 2 and the cylindrical liner 3, and the pressure resistance of the bottom of the bag body 1 is exclusively controlled by the internal reinforcement 2. Supplement. The pressure uniformly applied to the entire body of the cylindrical bag body 1 can be maintained not only by literally keeping the cylindrical liner 3 which is the outer periphery of the container bag in a cylindrical shape, but also by appropriately folding the upper edge outward. The fixing force at the fixed position of the internal reinforcing member 2 hooked on the upper portion of the cylindrical liner 3 is reinforced by the formed hook portion 17. The exterior body 7
Is configured so as to open downward, so that the opening can be used as a discharge port for taking out the contents, or a hand insertion port for attaching and detaching the lower lid 5 before and after transporting the container bag empty. It will also be available as The opening / closing means at this time is desirably the same opening / closing means 6 as the above-described upper opening of the exterior body 7. However, if the strength and restorability of the cylindrical liner 3 are excellent, the opening / closing means of the upper opening may be used. The form of the opening and closing means is not particularly limited.

The upper lid 4 and the lower lid 5 are desirably as rigid as possible, and the shape thereof is necessarily a circle having a diameter substantially equal to the outer diameter of the cylindrical liner 3. The circular shape may be a circle that fits in the inner space of the cylindrical liner 3, but in particular, in the case of the lower lid 5, the buffer space 10 may disappear when dropped or placed on a protruding object. Therefore, it is necessary to take a locking measure capable of stopping at the end of the cylindrical liner 3. Even when the diameter is set substantially equal to the outer diameter of the cylindrical liner 3,
By providing a fitting portion that fits into the opening of the cylindrical liner 3 along the periphery of the lid, the shape of the cylindrical liner 3 can be effectively maintained.

The container bag stands up due to the good self-sustainability of the cylindrical liner 3 and can be filled with about 1 ton of water. Even when the bag body 1 was vertically dropped from the bag, no example was found in which the bag body 1 inside the cylindrical liner 3 was broken. When transporting a container bag capable of storing a large amount of fluid in this way, a lift or a crane is inevitably used. However, a cue 18 corresponding to a lifting stroke at a work site is used in FIGS. As shown in FIG. 3, if they are provided as appropriate, a simple transfer becomes possible.

On the other hand, when the container bag is transported empty, the upper lid 4 and the lower lid 5 are removed, and the cylindrical liner 3 is folded flat together with the inner reinforcing member 2, the bag body 1 and the outer member 7, and It can be transported with the smallest volume per bag. As the cylindrical liner 3 of the container bag uses a multi-layered sheet of the paper sheet 8 and the cross sheet 9 as described above, even after being folded flat as shown in FIGS. No cracks are generated along the inner bag body, even if a sharp object collides from the outside, since the roll is wound a plurality of times as shown in FIG. The effect is extremely rare.

[0024]

As described above, in the container bag according to the present invention, the independence of the container bag is enhanced by integrating a highly rigid cylindrical liner as its bone, and when filling the contents, Stand up independently without using other filling equipment, and keep its filling port open. Even after filling, it is extremely good in shape retention and hardly collapses, and long-term storage and transportation in a stacked state are possible.
Also, the bag body is resistant to stabs and collisions from the outside, and if the buffer space is provided as described in claim 3, it is possible to prevent the bag body from being broken when dropped.

Further, when the air bag is carried by the empty body, the inner reinforcement body bag body and the outer body can be transported in the smallest volume state, for example, folded in two or four together.
In particular, when a cylindrical liner which is appropriately rigidified by laminating the paper sheet and the cross sheet according to claim 1 or 2 is used as the cylindrical liner, the cylindrical liner itself is lightweight. Therefore, not only can high transport efficiency be obtained for the maximum load weight,
Due to the extremely high restoring force, even if it is shipped or transported in two or four folds, when the filling port should be fully opened in preparation for filling the contents, it can stand alone and take the filling posture in a few seconds, Cracks and the like due to folding hardly occur in the cylindrical liner.

Moreover, once used, only the bag body which comes into direct contact with the contents needs to be replaced.
There is no cost required for cleaning and sterilization, and it can be used a plurality of times at low cost, so that not only manufacturing costs but also running costs can be reduced. Furthermore, if the opening / closing means according to claim 4 is employed for the exterior body, the remaining portion covering the upper lid and the lower lid can be evenly drawn from the entire circumference to the center of the cylindrical liner without bias, so that more protection can be achieved. The shape is enhanced and the packaging is stable, and the safety during transportation and storage is enhanced. As described above, the container bag according to the present invention has all the characteristics necessary for transporting or storing a fluid such as a liquid. There is also an advantage that it can be used instead of a bucket, such as stockpiling.
