Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inflatable tube seal and a containment using the same. The present invention also relates to a tube repair method using the tube type seal.

Flexible impermeable covers are used as containers for storing and transporting products.
It is known to be constructed by sealing to the substrate via an inflatable tether tube that fits into a groove. This mooring tube may be integrally formed as part of the cover, or may be a separate member from the cover, but in either case, when enlarged, it may form a groove or an impervious tube. The outer periphery of the cover is pressed against the bottom sheet to form an enclosure. After the packaging is formed in this way, the air inside the packaging is removed completely or to some extent, so that the cover that forms the packaging comes into almost close contact with the product on the base, and the overall appearance of the packaging is improved. The bulk of the containment body has been reduced. It is similar to a vacuum pack, and removing air in this way not only reduces the bulk as mentioned above, but also prevents deterioration and corrosion of the product inside, depending on the type of product. In addition to preventing
It has advantages such as long-term storage. Various types of such enclosures are known,
For example, British Patent Specification No. 1286544, No. 1439051
No. 1483945, No. 1511695, No. 1532002,
It is disclosed in No. 2038776, No. 2048822, etc.

Such known containers are commonly used as military equipment and are subject to abrasion and rough handling. As such, inflatable mooring tubes are sometimes subject to damage such as punctures or air leaks. Once damaged, if the mooring tube was integral with the cover and formed part of the cover, the entire cover would need to be replaced, or a new mooring tube would need to be fitted. . The present invention is directed to a method of repairing the damaged part while leaving the enclosure in a used state even if the mooring tube is damaged in this way.

According to one aspect of the present invention, in an enclosure having an inflatable tethering tube that fits into a groove to seal a cover to a substrate, a method of repairing a damaged portion of the tethering tube includes: , inserting an inflatable tube-type seal, which is closed at both ends, into the groove at the point of failure, and then inflating the tube-type seal to constrain the mooring tube against the outer wall defining the groove. This process consists of a step of sealing off the damaged area. It is sufficient that the tube seal be slightly longer than the length of the tether tube at the point of failure. Moreover, the internal pressure of the mooring tube when expanded is such that even if the remaining part of the mooring tube other than the damaged part is expanded again, the tube-shaped seal maintains the state pressed against the outer wall of the groove. make it higher than Therefore, it is desirable that the tube seal be made of a material that has less expansion than the mooring tube, such as a material that is relatively difficult to expand. The tube seal may be expanded to a pressure greater than the internal pressure of the mooring tube, but will not swell significantly. If a limit to the bulge is required, it can be adjusted by appropriate selection of materials and dimensions (eg, wall thickness).

In a preferred configuration, the tube-shaped seal is provided with protrusions at certain intervals along its length on its outer periphery for applying the localized pressure necessary to strongly compress the mooring tube against the outer wall of the groove. is desirable. This protrusion may be integrated with the tube seal, but it may also be made of a separate member such as an O-ring made of an elastic material and mounted on the tube seal. is the most convenient. Therefore, it is convenient to use a separate member to constitute the protrusion. The number of these protrusions may be two, in which case they are preferably fitted into the tube-shaped seal so that a compressive force is applied to the mooring tube on both sides of the breakage point of the mooring tube. In addition, if the number of such projections is not limited to two, the mooring tube can be pressed even more securely.
Preferably, four O-rings are used. If four O-rings are used, the position of the three O-rings can be adjusted as desired to apply pressure to the mooring tube on either side of the failure point.

According to the present invention, when a mooring tube is punctured, a tube-type seal is inserted at an appropriate location and expanded to compress the mooring tube against the outer wall of the groove, thereby sealing the puncture location on the mooring tube. be able to. Thereafter, the remaining portion of the tether tube is expanded and the enclosure can be used in accordance with normal usage. The tube seal thus acts to seal across the remainder of the circumference of the mooring tube across the puncture.

Further, the tube-type seal according to the present invention preferably comprises an outer tube made of a material that is relatively difficult to expand and an inner tube made of a material that is easy to expand. When a tube-type seal having such a configuration is used, only the inner tube is enlarged, so there is no need to provide airtightness to the outer tube. The outer tube acts by constraining the inner tube, substantially confining it within the groove, so that when the inner tube is inflated, pressure is applied through the outer tube and the protrusions on the outer periphery of the tube-type seal. However, although a small portion of the outer circumference of the outer tube protrudes from the groove, most of it remains within the groove. A one-way gas introduction valve may be provided to expand the inner tube.

When repairing a damaged mooring tube,
It is desirable to apply a sticky material, paste, or other soft material to the tether tube around the point of failure, particularly in the area where pressure is applied to the tether tube from the protrusion. Placing such a sticky material or other filler in the mooring tube will ensure a seal against gas leaks due to the pressure acting on the mooring tube, and will also prevent pressure leaks when the mooring tube is re-inflated. It is possible to prevent this from happening.

In some cases it may be advantageous to use a flexible metal strip between the projection and the surface of the tube seal. This way, the force created by the internal pressure when the tube seal (or the inner tube of the tube seal) is inflated will be transmitted through the O-ring, and the mooring tube will be moved without deforming the tube seal at the protrusion. It can be compressed.

Furthermore, if a surrounding member or a shield member such as a metal cover is used for the tube seal, the tube seal can be restrained and its degree of expansion can be restrained. In this case, the enclosure member covers most of the circumference of the tube seal to prevent the tube seal from extruding from the groove when expanded, and to distribute pressure over the entire surface of the compressed mooring tube. be able to. Such metal shielding or surrounding members may be provided with raised ridges or similar ribs that exert localized pressure on the mooring tube in order to force the mooring tube against the groove. It's convenient.

When pressing the mooring tube against the groove, if the mooring tube is a separate member from the cover, the outer periphery of the enclosure will be located between the mooring tube and the groove. Similarly, if a flexible impermeable sheet with grooves around its periphery is used as the bottom of the enclosure, this too will be pressed against the outer wall of the groove, i.e. compressed. I am made to do so. Thus, the tube seal not only compresses the mooring tube to prevent gas leakage, but also provides the necessary seal between the enclosure and the groove or bottom sheet.

A one-way air inlet valve may be provided to expand the tube seal. Since the damage caused by a puncture or air leak is not large, but covers a very short distance or diameter, a short tube seal is sufficient to repair the damage. Because it is so short, it can be quickly expanded using a portable pump, and once expanded, the damaged area can be reliably closed. If a surrounding member or a shield member is used as described above, a hole through which the air introduction valve passes may be provided in the surrounding member or shield member.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to that, first
The structure of the known enclosure shown in the figure and FIG. 2 will be explained.

The known enclosure shown in FIG. 1 consists of a flexible, impermeable base 10 and a flexible enclosure or cover 11 of an impermeable material, for example butyl rubber. This enclosure can generally be used as a flexible shelter, for example for a motor vehicle. The substrate 10 may be provided with a suitable solid member to form a bedding or support for an automobile or other item to be stored. At the periphery of the cover 11, the cover 11 is attached to the base 1.
to seal against zero, a channel, or
Extending is an inflatable tethering tube 12 which can be inserted into a channel member 13 forming the frame structure. This anchoring tube may be integral with or attached to the enclosure 11, or it may be an entirely separate and separate member.

The known enclosure shown in FIG. 2 consists of an impermeable metal substrate 15, for example a pallet, and a flexible enclosure or cover 11 of an impermeable material, for example butyl rubber. . At the periphery of the cover 11, similar to that shown in FIG. Extending. This mooring tube 12 may also be integrated with the cover 11 or attached thereto, or may be a completely independent separate member. Particularly in the latter case, it should be mounted in the groove 16 and held in a holder there.

Now, in the method of using the container shown in FIG. 1 and FIG. Seal by expanding. Thereafter, a vacuum pump is used to evacuate the air inside the enclosure. Then, in the configuration shown in Figure 1, the cover 11 and the base 10 will come into close contact with the product, and in the configuration shown in Figure 2, only the cover 11 will come into close contact with the product, thus completing the packaging body. It is.

The present invention particularly relates to a mooring tube and a structure in which the tube is punctured or partially ruptured.
Alternatively, it is related to repair in case of damage such as air leakage.

An inflatable tube seal 20 for repairing damage in mooring tubes is shown in FIGS. 3 and 4, suitable for the configuration shown in FIG. 1, and shown in FIG. It is used as shown below. In the embodiment shown in FIG. 5, the cover 11 and the mooring tube 12 are shown as being integral.

Assuming that there is a damaged part in the mooring tube 12,
To repair the damage, a short tube seal 20, closed at both ends, is inserted into the channel 13 in the vicinity of the mooring tube 12. Before use, the tube-shaped seal 20 is closed at both ends and is flat like the body of a long-bladed fish, and is provided with a check valve 21 for inflating the tube-shaped seal 20 by letting air into it. It is being The width of the tube seal 20 is sufficient to allow a portion of the check valve 21 to emerge from the outer wall of the channel 13 when inserted into the channel 13. This tube-shaped seal 20 is made of a flexible impermeable material (for example, a polymer material) that is wholly or partially reinforced with non-inflatable fabric to suppress the degree of swelling when inflated. has been done.

The tube seal 20 can be expanded by introducing air through the check valve 21, but it is preferable to expand the tube seal 20 until the internal pressure becomes higher than the internal pressure when the mooring tube 12 is expanded. This expansion of the tube seal 20 compresses the mooring tube against the outer wall of the channel over a portion of the length of the seal 20. The length of the tube-shaped seal 20 is sufficient to cover the damaged part of the mooring tube 12 (indicated by a broken line in FIG. By holding down the mooring tube 12 with the expanded tube seal 20, the remaining portion of the mooring tube 12 can be expanded again, and the cover 11 can then be sealed to the channel member 13 as usual. .

When the tube seal 20 is positioned and expanded as described above, the cross section of the expanded tube seal 20 will take on an approximately "8" shape as shown in FIG. is compressed to such an extent that it comes into firm contact with the corresponding outer walls of the base body 10 and the channel 13. At the same time, the damaged area is closed by contact with the tube-shaped seal 20. As previously mentioned, since the tube-shaped seal 20 is inflated to such an extent that its internal pressure is higher than the bulk internal pressure of the mooring tube, the remainder of the mooring tube can be re-inflated at any time, and in this way the entire As a result, a pneumatic seal is formed.

By the way, if the tube-shaped seal 20 having the configuration shown in FIGS. 3 and 4 is expanded without using any restraining material, the expansion degree of the cloth-reinforced composite material is limited, so it will have a finite straightness. It will have a cylindrical shape. On the other hand, when it is restrained, it is narrowed by the upper opening of the channel member 13, as shown in FIG.
It becomes a so-called hyotan shape. Therefore, the safe tolerance value for the internal pressure of the tube seal 20 is determined depending on the tensile strength of the composite material that constitutes the seal 20.

FIG. 6 shows an example in which the tube-type seal 20 shown in FIGS. 3 and 4 is used in a container having the structure shown in FIG. 2. In this embodiment, the bottom sheet 10 is absent and the breakage point of the tether tube 12 is similar to that shown in FIG. 5, except that it is pressed against the rigid outer wall 25 of the hermetic base.

In both the embodiments shown in FIGS. 5 and 6,
Although the tube seal 20 extends above the groove, the degree of expansion is limited by the non-expandable nature of the material.

In the embodiment shown in FIG. 7, a shielding member or surrounding member 27 is used to suppress expansion of the tube seal 20. This shielding or surrounding member 27 can be used not only with tube-type seals made of inflatable material, but also with the tube-type seals shown in FIGS. 3 through 6. In any case, in the embodiment of FIG. 7, the channel 13 is the same as shown in FIG. 1, and the mooring tube 12
is shown as being integrated into a part of the cover 11. Channel 13 may be fixed to or integrally formed with the impermeable substrate, or may be separate from it. Particularly in the latter case, an impermeable sheet may be provided on the upper surface of the base body, the peripheral edge of the sheet may be fitted into the channel 13, and the mooring tube may be enlarged and sealed with the cover 11.

Surrounding member or shielding member 2 shown in FIG.
7 is made of elastic metal, and the channel member 13
A neck portion 28 is formed which engages with a curved portion 29 at the upper edge of. Therefore, in the event that the mooring tube 12 is damaged, the inflatable tube seal 26 is inserted into the channel 13, and the aforementioned surrounding or shielding member 27 is then narrowed inwardly against its own elasticity. , the tube-shaped seal 26 is covered from above so that the neck portion 28 engages with the curved portion 29 of the channel member 13. At that time,
The valve 21 of the tube-shaped seal 26 exits through a hole 30 formed in the enclosure or shielding member 27.

Thereafter, the tube seal 26 is expanded by introducing air through the valve 21, in such a way that an internal pressure higher than that of the mooring tube 12 is generated. In this way, the mooring tube 12 will be pressed against the outer wall of the channel over a short distance by the tube seal 26, thus occluding the damaged portion of the mooring tube 12 as before. and the remaining portion can be expanded again as normal.

FIGS. 8 and 9 show further embodiments. In FIGS. 8 and 9, reference numeral 31 denotes a channel-shaped member, which is placed on a strong support 32 and is a sheet made of an impermeable material forming an impermeable layer constituting the bottom of the enclosure. The peripheral edge of 33 is inserted. The cover 34 has an inflatable mooring tube 35 which is attached to the channel 3.
1 and when enlarged,
The cover 34 and the bottom sheet 33 are sealed. An inflatable tube-type seal 36 with both ends closed is inserted into the channel member 31 at the damaged portion of the mooring tube 35 while being held by the surrounding member 37. Figures 7 and 8
The surrounding member 37 in the embodiment shown in FIG.
Lip portion 3 engaging with lip portion 39 of channel member 31
8 is formed on the longitudinal edge, and a longitudinal protrusion 139 and a pair of circumferential protrusions 40, 41 are formed at the portion where the mooring tube 35 is pressed against the outer wall of the channel member. These protrusions 139, 40,
41 serves to exert local pressure on the mooring tube to force it flat and to securely clamp the bottom sheet 33 and the outer wall of the channel 31. In this embodiment as well, the tube type seal 36 is provided with an air introduction check valve 42, which when set as shown in FIG. It's getting old.

In the configurations shown in FIGS. 8 and 9, damaged parts of the mooring tube can be repaired in the same way as in the embodiment shown in FIG. It is clear that the material may be made of either a material that is easy to expand or a material that is difficult to expand.

The embodiments of FIGS. 10 to 17 illustrate an advantageous repair method in the event of a ruptured mooring tube.

The rupture point, designated 113 in FIGS. 10 and 11, generally occurs inside the mooring tube. This is because the valve for introducing air to expand the mooring tube protrudes outward from the enclosure and is supported by the portion of the mooring tube made thick by laminating multiple layers. Proper insertion of the mooring tube into the channel 120 (FIGS. 16 and 17) ensures that the mooring tube is supported and does not swell too much when inflated, thus preventing rupture. The internal pressure is maintained at an appropriate level without causing any damage. Therefore, a rupture of the mooring tube as shown is likely to occur if the mooring tube is improperly inserted into the channel. Since the enclosure is continuously connected to the channel, and if it were to rupture, the rupture point would be on the inside, so in the embodiments to be described, the enclosure and the rupture point of the mooring tube are connected to the channel. 120 inner wall surface 1
By pressing strongly against 21, the rupture point is closed. This can be accomplished by using a tube-type seal as shown in FIGS. 12 and 13. The tube type seal shown in FIGS. 12 and 13 consists of a restraining outer tube 123 made of a substantially non-expandable material, and an impermeable inflatable material such as butyl rubber.
It consists of an inner tube 122 housed inside the tube 23. The material constituting the outer tube 123 is
Although substantially non-inflatable, it must be flexible and, for example, may advantageously be constructed from a sheet of butyl rubber reinforced with fabric. Further, the outer tube 123 is not necessarily impermeable, and both ends thereof do not necessarily have to be closed. However, as shown in FIG. 12, it is desirable to have both ends 124 (only one side shown) closed. On the other hand, the inner tube 122 is provided with a Schürader pneumatic valve 125, which is a check valve similar to that used in pneumatic tires of vehicles, and this valve 125 passes through the outer tube 123 and is supported. ing. Of these, tube 122
has both ends closed and extends almost the entire length inside the outer tube 123.

A plurality of O-rings 126, preferably of circular cross section, are mounted to the tube seal. The mounted O-ring 126 can be slid on the tube seal, so when actually using the tube seal, position it as described below.

To repair the rupture site 113, the rupture site of the mooring tube 111 is cut out and a hole 130 is drilled, as shown in FIGS. 14 and 15. this hole 1
30 into the interior of the mooring tube 111, the first
As shown at 131 in FIG. 5, a viscous paste sealant is applied. The sealant may be, for example, unvulcanized raw butyl rubber mix. Other sealants can also be used, but in short, they should be compatible with the material of the mooring tube and provide an airtight seal while remaining in a paste form when the mooring tube is compressed.
Any kind of sealant may be used.

The tube seal is then inserted into the channel near the rupture point of the mooring tube as shown in FIG.

In FIG. 16, the channel member 120 includes a part of the impermeable sheet material 132 that constitutes the base of the containment body, and an impermeable sheet material 11 that forms the cover of the containment body.
0, where the mooring tube 111 is formed, is inserted. A tube type seal is inserted there, but in this case, most of the tube type seal, except for the valve 125 and the part where the valve 125 is attached,
It will fit into the channel member 120.

Air is then introduced through valve 125 to inflate the tube seal until an internal pressure greater than that required to inflate mooring tube 111 is created. As an example, 40~
It is common to expand the pressure to an internal pressure of 75 psi (276 kPa to 517 kPa). Then, the inner tube 122 will swell until it comes into contact with the inner surface of the outer tube 123, but the outer tube 123 will no longer swell any further, and the internal pressure will be reduced to the O-ring 1.
26 to press the mooring tube 111 against the outer wall of the channel. In this way, the pressing force is transmitted to the mooring tube via the O-ring, which essentially forms the outer circumferential ridge of the tube seal. If more than one O-ring is used, at least two O-rings should be mounted on the tube seal on either side of the rupture point on the mooring tube.
By doing so, the portion 131 to which the sealant is applied in the mooring tube is pressed down. In this way, a seal can be achieved by ensuring that the tether tube is compressed on both sides of the rupture point. The remaining O-rings are placed between the aforementioned two O-rings and each end of the tube seal to further ensure the seal. Once the rupture is sealed in this way, the tether tube can be re-inflated as usual. The internal pressure in the mooring tube is lower than that of the tube seal, e.g. 10 to 15 psi.
(69 to 103kPa), the mooring tube can be kept compressed with a tube-type seal.

In the embodiments shown in FIGS. 10 to 17, it is possible to use the surrounding member or shield member used in the embodiments shown in FIGS. It is used by covering the tube seal between two O-rings. This prevents the tube seal from deforming at the O-ring and reduces the effective clamping pressure that is transmitted through the O-ring from the tube seal to the mooring tube. The pressing force can be transmitted only through this O-ring.
