DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure-resistant enclosure which is particularly suitable for storing a high-pressure liquid or gas as an object to be stored.

[0002]

2. Description of the Related Art When storing objects such as high-pressure liquid and high-pressure gas, a closed container having a high-strength pressure-resistant structure is used. Conventionally, this pressure-resistant closed container is generally made of a high-strength fiber-reinforced plastic or metal.

[0003]

However, constructing a closed container using high-strength fiber-reinforced plastic or metal as a material not only increases the cost in terms of material and manufacturing, but also allows storage when not in use. In addition, it is troublesome in terms of storage and transportation, and is troublesome in terms of disposal after use. The present invention has been made in view of the above problems, and has as its object to provide a pressure-resistant enclosure that is convenient for storage and transportation when not in use, facilitates disposal after use, and can be produced at low cost and has excellent use durability. It is.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a pair of cylindrical cloth members having a strength in a circumferential direction larger than a strength in a longitudinal direction, and a pair of cylindrical cloth members in which an object is contained. One of the cloth members is inserted into the other cylindrical cloth member so as to cross each other, and the outer cylindrical cloth member covers the whole of the other cylindrical cloth member located inside the outer cylindrical cloth member. It is characterized by being provided in. As the yarn of the fiber which is knitted in the circumferential direction of the tubular cloth member, a so-called seamless yarn having a high tensile strength and having no seam can be used.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a tubular cloth member, the strength per unit (kgf / cm) in the length direction (cylinder length direction) may be higher than the strength in the circumferential direction. If you want to make a bag from things,
No matter what kind of terminal treatment such as bonding, the strength in the length direction is generally weaker than the strength in the circumferential direction in the terminal processing part. In order to eliminate this drawback, in the present invention, a pair of tubular cloth members are assembled by crossing each other. As the material of the tubular cloth member, aramid fiber, polyester, polypropylene, or the like having a small elongation is preferable. Nylon, etc. with large elongation even if the strength in the circumferential direction is large,
It is not preferable as the material of the tubular cloth member. That is, if the tubular cloth member has a large elongation, when the internal pressure is applied to the object to be accommodated in a state where the tubular cloth member is assembled in a cross, the internal pressure cannot be satisfactorily received by the tubular cloth member, and as a pressure-resistant enclosure, This is because use becomes difficult.

[0006] The cloth member has a hollow cylindrical shape, and generally has a greater strength in the circumferential direction in the terminal processing section than that in the length direction. One set of such a tubular cloth member is prepared, and one of the tubular cloth members (inner cylinder) contains an object to be accommodated, and then the other tubular cloth member (outer cylinder).
Insert into and overlap. The pair of superposed tubular cloth members are disposed so as to cross each other. For this reason, when the internal pressure of the pressure-resistant enclosure acts largely in the cylinder length direction of the inner cylinder, it can be handled by the fibers forming the circumferential direction of the outer cylinder. Similarly, the internal pressure acting in the length direction of the outer cylinder can be handled by the fibers forming the circumferential direction of the inner cylinder. As a result, the pressure resistance against the pressure-resistant enclosure is improved not only in the overlapping direction of the pair of the inner cylinder and the outer cylinder, but also in the two intersecting directions. In addition, in order to secure the strength of the corner portion of the crossed and overlapped cylindrical cloth member, the outer cylindrical cloth member covers the whole of the other cylindrical cloth member positioned inside the outer cylindrical cloth member. Is provided.

[0007] The length of the inner cylinder is the width of the outer cylinder (inner diameter).
The length is set longer than the required amount of elongation, that is, the amount by which the outer cylinder expands when an internal pressure is applied. Thereby, the internal pressure can be satisfactorily received in both intersecting directions, and a pressure-resistant enclosure having high use durability can be obtained. In addition, the pressure-resistant enclosure of the present invention is usually formed by doubling a pair of two cylindrical cloth members. However, in order to further increase the pressure-resistant strength, a set of three or more cylindrical cloth members is formed. To form a high-pressure enclosure with three or more layers.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing a pressure-resistant enclosure according to the present invention, FIG. 2 is a perspective view showing the pressure-resistant enclosure in an assembled state,
FIG. 3 is a sectional view taken along line AA of FIG.

As shown in FIG. 2, in this embodiment, the pressure-resistant enclosure is applied to a closed container for liquid.
Has a substantially square plane and a substantially elliptical side surface. As shown in FIG. 3, the cross-sectional structure of the liquid closed container 1 has a flat rectangular closed bag 2 in which a liquid W such as water is stored, and the closed bag 2 is made of a flexible material. Here, it is formed by fusing the end of the polyethylene tube. The airtight bag 2 is surrounded by a pressure-resistant enclosure 3 having a double structure, and the pressure-resistant enclosure 3 includes a pair of tubular cloth members 4 and 5. This tubular cloth member 4,
Numeral 5 is made of a non-stretchable material (including a micro-stretch which has a small elongation with respect to the above-mentioned flexible material). Here, after winding a canvas roll into a tubular shape, its ends are adhered. Is formed. Therefore, the pressure resistance of the tubular cloth members 4, 5 can be adjusted by adjusting the number of turns of the canvas roll.

The fibers in the circumferential direction of the tubular cloth members 4 and 5 are made of seamless yarn, and the fiber strength in the circumferential direction is greater than the fiber strength in the longitudinal direction (axial direction) of the tubular cloth members 4 and 5. It has become. One cylindrical cloth member 4 in which the closed bag 2 is included
Is inserted into the other cylindrical cloth member 5, and the pair of cylindrical cloth members 4, 5 are arranged so as to cross each other in a cross shape. A liquid hole 6 through which liquid W flows in and out of the closed bag 2 is formed through the tubular cloth member 4 and the closed bag 2, and an openable / closable lid 7 is attached to the liquid hole 6. ing. In order to secure the strength of the corners of the tubular cloth members 4 and 5 which are overlapped and crossed, the outer cylindrical cloth member 4
Is provided so as to cover the entirety of the other cylindrical cloth member 5 located inside.

The pressure envelope of the above construction comprises a pair of tubular cloth members 4, 5 whose fiber strength in the circumferential direction is greater than fiber strength in the longitudinal direction, and the pair of tubular cloth members 4, 5 are mutually connected. They are arranged orthogonally. As a result, even if the liquid W is stored and sealed in the sealed bag 2 in a high pressure state, it can withstand this. In other words, when the internal pressure of the sealed bag 2 acts largely in the length direction of one of the tubular cloth members 4, it is received by the circumferential fiber strength of the other cylindrical cloth member 5. Further, when the internal pressure of the closed bag 2 acts largely in the length direction of the other tubular cloth member 5, it is received by the circumferential fiber strength of the one cylindrical cloth member 4. Therefore, the pressure resistance of the pair of tubular cloth members 4 and 5 as a whole is increased not only in the thickness direction (vertical direction) but also in the vertical and horizontal length directions (horizontal direction). That is, in the pressure-resistant enclosure of the present example, even if the pressure of the liquid W in the sealed bag 2 becomes considerably high, a pressure-resistant structure that can cope with this is obtained.

The present invention is not limited to this embodiment. For example, the sealed bag 2 can be formed of a flexible material such as rubber or waterproof oil paper. In addition, the sealed bag 2 can contain various substances such as liquid gas, carbonated drinking water, beer and high-pressure gas,
In particular, it can be used as a sandbag by containing sand. Further, the crossing angle of the pair of tubular cloth members is set to 90 degrees in the embodiment, but is not limited to 90 degrees and can be set to a required angle according to the multiplex structure.

[0013]

As described above, according to the present invention, a pair of cylindrical cloth members having a greater strength in the circumferential direction than the length direction are overlapped with each other so as to intersect with each other. The pressure resistance not only in the polymerization direction but also in the cross direction is increased, and the cloth enclosure having a high pressure resistance and durability and a simple structure can be mass-produced at low cost. In addition, since the pressure-resistant enclosure of the present invention is made of cloth, it can be folded and accommodated when not in use, is convenient for transportation, and is easy to dispose after use as compared with conventional fiber-reinforced plastic or metal. There is an excellent effect.
