[0001] The invention relates to transportation field and can be used for storage of bulk
cargoes, such as bulk building materials, raw materials for metallurgy industry, chemical
industry products, raw sugar, grain, coffee and other food products.
[0002] There is known a soft container for transportation and storage of cargoes (Patent
RU 2228287, published on 10.05.2004), which comprises a sleeve and bottom. The container bottom
is formed by four long petals bent from outside to the center and connected with the
sleeve and four short petals located between the long petals. The short petals are
located above the long petals overlaid against each other and drawn to the center
of the bottom with rope member, and specifically the side edges of each short petal
are stitched on above the long petals adjacent to it for the length providing tightness
of the bottom in the places of connection of the petals for the case of their maximum
possible opening during container discharging. The disadvantage of such design is
its low reliability.
[0003] A soft container for transportation and storage of bulk cargoes (Patent of Ukraine
for invention No.
72054, published 15.07.2003) is the closest to the claimed invention by its technical essence, purpose and achieved
result. It comprises a vessel with upper filling opening and lower discharging opening,
and bearing framework. The invention also contains a locking device, bearing net with
lifting loops and with bottom. According to this known invention, the vessel is disposed
in the bearing net and connected with it in the upper part by means of detachable
joint consisting of loops successively connected with each other and fastened to the
vessel and to the bearing net, with closing of the last group of the loops by means
of tie-up string. In particular, the extension of the loops fastened to the vessel
is embodied in the form of tapes disposed under angle to direction of threads forming
warp and weft of the vessel fabric, the bearing net has a bottom with opening and
rim member connected with vessel discharge opening, the vessel is provided with sleeves
having tape loops for strangling and system of valves, and one of the valves is fastened
on the vessel filling opening.
[0004] The main disadvantage of the known device is that it is inconvenient in use. It is
due to the following causes. The container consists of two parts: bearing framework
in the form of net and internal insert which is fastened in its upper part to the
bearing framework in detachable way.
[0005] In addition, this device is unreliable in use. The vessel is fixed only at the expense
of passing the sling tapes through the tunnel. This method is efficient only for the
main part of the vessel (insert), but, when the large soft container is transported
in the folded condition, the lower its part, in particular the discharge valve, shall
remain in the center of intersection if the sling tapes on the bottom, or else, if
the central discharging valve is displaced from the discharge opening, the discharge
may simply fail.
[0006] Besides, this known container has the sling structure protected from damage with
the help of protective tunnels, but the transverse rings are located outside and are
very sensitive to damage since they are not protected. The known container has protective
jacket on the bag bottom.
[0007] In addition, it follows from the known patent that transverse rings are attached
with fixing tie-up tape sewn to the protective tunnel. Since the tape is sewn to material,
its integrity and tightness is disturbed due to punching openings in the material
with needle. Thus, there exists a high probability that during use the tape may tear
off, just leaving a hole in the material.
[0008] Further, in the known container, the bottom of sling net is formed by intersection
of main sling tapes. The fact is that, for forming a bottom capable to withstand multi-tonnage
cargo, such intersection is insufficient since it is very small and has no rigid adhesion
of tapes, without which the sling structure being under pressure of cargo will always
go apart with its tapes taking different positions.
[0009] This invention is intended for solving the task of improving convenience of container
use during handling multi-tonnage bulk cargoes, as well as improving reliability of
the container during its use.
[0010] The set task is solved in that the large soft container comprises a vessel with upper
charging opening and lower discharging opening, bearing framework and discharging
mechanism. According to the invention, the device is additionally provided with soft
sling ring for distribution of loads, which is passed through additional external
loops of the main slings and alternately through additional loops on the upper perimeter
of the cylinder, which, in turn, are embodied in the form of the load distribution
triangle.
[0011] According to one of the embodiments of the invention, the container is additionally
provided with protective jacket, which protects the entire surface area of the cylinder
and bottom and is attached along the upper perimeter of the cylinder by means of detachable
connection.
[0012] According to further embodiment of the invention, all the loops for connecting the
cylinder with the sling structure are embodied in the form of the load distribution
triangle.
[0013] According to one more embodiment of the invention, the bottom of the bearing framework
is formed by intersection of sling tapes and has reinforced transverse tapes, with
retention of dimensions between the tapes which connect these additional sling tapes
forming at least one octagon between them.
[0014] According to one more embodiment of the invention, the bottom of the bearing structure
is fastened to the bottom of the cylinder to prevent displacement of the container
bottom.
[0015] According to additional embodiment of the invention, the transverse rings are fixed
with tunnel detachable connections.
[0016] According to the invention, the set task of improving convenience of use is solved
in that the offered device is additionally provided with additional loops for fixing
the bottom of the cylinder to the main sling structure which excludes displacement
of the neck from the discharging place, even after transportation of the container
in empty folded condition.
[0017] Besides, improving reliability of the container is also promoted by the fact that
the protective jacket is fastened along the entire perimeter of the cylinder in its
upper part. For this purpose, a collar with detachable connection system is welded
along the perimeter of the cylinder in its upper part. Along the entire perimeter
of the outer jacket, a detachable connection system is also provided, and thanks to
it they are connected. The connection is provided with the use of the following principle:
the main cylinder with sling structure is pulled into external jacket embodied in
the form of a cylinder with open top provided with fastening system and bottom with
discharging valves, and is fixed along the upper perimeter by means of the collar
with fastening system.
[0018] In the offered embodiment of the container, instead of fastening sewn tapes, there
is used a transverse tunnel with detachable clasp which is welded to the longitudinal
tunnel by heat-sealing method, which retains integrity of the structure.
[0019] In the offered container the bottom of sling structure is provided by intersections
of the main tapes, these tapes are reinforced with transverse tapes forming at least
one octagon, these tapes also having transverse tapes between them which prevent their
going apart under load. The bottom of the sling structure has a strong transverse
system of fastening the tapes to each other.
[0020] The reliability is also improved due to the fact that the protective jack has the
height of the internal cylinder and repeats its shape both for the bottom and the
entire space. Therefore, the external protective jacket protects the container from
damage both on the bottom and over the entire surface.
[0021] Such fastening triangles are disposed in the upper part of the cylinder in the places
of going the sling tape, as well as on the cylinder between sling tapes.
[0022] This invention is illustrated by the following drawings, where Fig. 1 shows the general
view; Fig. 2 shows a separate view of sling structure.
[0023] The container has such main parts (Fig. 1

Fig. 2): vessel 1 with upper charging opening 2 and lower discharging opening 3,
bearing framework 4, discharging mechanism 5, soft sling ring for distribution of
loads 6, which is passed through additional external loops 7 of main slings 8 and
alternately through additional loops on the upper perimeter of cylinder 9, which,
in turn, are embodied in the form of load distribution triangle 10. The protective
jacket 11 protects the entire surface area of cylinder and bottom and is fastened
along the upper perimeter of the cylinder with the help of detachable connection 12.
All the loops of connection of the cylinder with sling structure are embodied in form
of the load distribution triangle 13. The bottom of the bearing framework is formed
with the help of interception of the sling tapes, has reinforced transverse tapes
14, with retention of dimensions between the tapes connecting these additional sling
tapes which form at least one octagon 15 between them. The bearing structure bottom
is fastened to the bottom of cylinder 16 to prevent displacement of the container.
The transverse rings 17 are fixed with tunnel detachable connections 18.
[0024] The device is used as follows. The soft container for transportation and storage
of bulk cargoes is used according to the known procedure: charging, transportation
to the user, discharging. Before charging bulk cargo, it is necessary to check if
discharging opening 3 is closed with the help of discharging mechanism 5. Further
the container is lifted, being hung on main slings 8, and charging opening 2 is connected
with the bulk-cargo hopper. Prior to discharging, it is necessary to unlock discharging
mechanism 5. After this, lower discharging opening 3 is released, through which the
bulk cargo is discharged from the container.
[0025] Thus the invention provides solution of the task aimed at improving convenience of
work with multi-tonnage bulk cargoes, as well as improving reliability of the container
during use.
