Container for transport of products, especially in the form
of coils
The present invention is a container for the transport
of products, especially in the form of coils, designed to
be moved by cranes, forklift trucks, overhead cranes, or
container carriers.
A container for transport of various products
including those of a circular cross-section, in which the
floor is equipped with deflected covering plates is known
from the American patent application US2003106822. In the
closed position the flaps form one plane with the floor,
allowing transport of products on pallets, or having a
stable basis. In the open ,position the flaps reveal
cavities located in the floor of the container, which
provide two points of support for oval objects located
horizontally. If the object has a large diameter, the
points of support are provided by deflected flaps which, in
the open position, form an extension of a cavity in the
floor. The disadvantage of the solution, according to the
invention, is that the floor of the container must be thick
in order to provide enough space for sufficiently deep
cavities Therefore, while maintaining the standard external
dimensions of the container, the amount of space available
inside is reduced.
In patent application W02008107626 a container holding
a floor adapted to carry cylindrical objects is shown. The
container is equipped with sets of pivoting supports in the
floor. The supports can be arranged perpendicularly or
parallel to the longer axis of symmetry of the floor. In
the closed position the supports form one plane with the
floor, while in the open position they form a trough in the
shape of an inverted isosceles trapezium which provides

WO 2013/180586
PCT/PL2012/000093

three points of support for oval objects. In the present
solution, the mechanism locking the supports in the open
and closed positions is in the floor, directly under the
support. The container is also equipped with a rigid,
removable roof, so that products can be loaded and unloaded
from the container also by a cranes or a high lift forklift
truck. .In view of the fact that the supports for oval
objects are narrow, the line of contact with the object is
short. Thus, to ensure a high stability of a transported
oval object, it is necessary to use at least two pairs of
supports. In the case of a short object, the distance
between each pair of supports may be too large for such an
object to be held by two sets of supports. Furthermore, a
system locking the supports in the closed and open
positions, due to the relatively small dimensions on which
large forces act in the case of heavy loads, is subjected
to rapid wear.
The aim of the invention is to elaborate a container
having a floor adapted to transport cargo on pallets, free-
standing, and cylinder-shaped objects such as steel coils,
which provides high stability for the transport of objects,
irrespective of their length, while still being resistant
to mechanical damage.
The essence of the solution according to the invention
is a container for the transport of products, particularly
in the form of coils, comprising the floor, two side walls,
a front wall, two doors with a lock, and a removable rigid
roof with a fastening mechanism, where the floor is
equipped with at least one pair of pivoting supports with a
locking system, grouped in at least one pair, placed along
its longer axis of symmetry, opposite to each other, which,
in the closed position, form one horizontal plane with the

floor, while in the raised position they form a trough. The
solution is characterized in that the pivoting support,
being a part of one pair, is made up of a flap connected to
the flap support or a wide flap connected to the wide flap
support. The flap and the wide flap are movably connected
to the floor by means of hinges located on one of their
edges. In addition, the flap and the wide flap are movably
connected, by the other edge, to the flap support or to the
wide flap support by hinges. The floor has two grooves,
parallel to each other and running through its whole
length, located on both sides of the longer axis of
symmetry of the floor. The grooves are lying horizontally
under the flap supports or wide flap supports.
Preferably, the flap and the wide flap and the flap
support and the wide flap supports are in the shape of a
rectangular. The floor has preferably two pairs of flaps
and two pairs of flap supports of corresponding width, that
are on the shorter ends of the floor, and between them
there are two pairs of wide flaps and wide flap supports of
corresponding width. The flap and the flap support are
narrower than the wide flap and the wide flap supports.
Preferably, the flap and the flap support have three hinges
each, and the wide flap and the wide flap supports have
five hinges each. The flap and the wide flap are equipped
with two oval handles. In addition, the flap and the wide
flap are equipped with an anti-slip layer. The anti-slip
layer is made of rubber. Preferably, the fastening
mechanism on the roof consists of two locking bars
positioned perpendicularly to the longer edges of the roof.
On the roof edges, butting the side walls, the front wall,
and the beam there is a sheet rubber gasket. Preferably, on
the upper side of the roof there are two large handles
located along the longer axis of symmetry of the roof, the

holes of the handles being parallel to the longer edges of
the roof and four small handles located at the longer edges
of the roof, the holes of the handles being perpendicular
to those edges. Preferably, the lock of each door leaf
consists of two locking bars At the edges of the doors
there is a sheet rubber gasket. Each door leaf preferably
has a latch hook. Each of the side walls has two attachment
mechanisms for the roof, which are connected to the locking
bars. Each of the side walls has a door hold compatible
with the catch. hook. Preferably, the floor is equipped with
small hinged rectangular flaps, located on opposite sides
of the longer axis of symmetry of the floor, the flaps
being mounted on strap hinges and are placed under the flap
supports lying horizontally and/or wide flap supports. The
floor has two rectangular through holes placed under its
usable layer, parallel to the shorter axis of symmetry of
the floor, the spacing of the holes being identical to the
spacing of the two large handles situated on the roof. On
each of the side walls, under the upper edge, there are two
air holes. Preferably, the usable layer of the floor is
made of a flat sheet. The fill of the door frame structure
consists of a flat sheet with moulded sections while the
fill of the structure of the side walls, the front wall,
and the roof is made of a trapezoidal sheet, where the roof
surface in the area extending between its longer edges,
where the big and small handles are positioned, is made of
a flat sheet. Preferably, the fill of the roof frame
structure is a flat sheet with moulded sections. On each
side wall, along its upper and lower edges, eight small
handles are located. Above the upper edge of the door there
is a beam which is detachably connected to the side walls.
Preferably, on the corners of the container structure there

are corner fittings. Preferably, on the corners of the
container structure there are corner fittings.
An advantage of the invention is to provide a
container which is adapted to carry objects on pallets,
free-standing, and oval objects such as steel coils. The
solution according to the invention makes the carrying of
oval objects of different lengths possible. In the case of
transport of short coils, only one support to stabilize may
be used and the rest of the floor may be left flat. This
allows to maximize the container surfaces. A long line of
contact of a cylindrical object with a support ensures more
friction and thus greater object stability in the case of
moving the container. In addition, the anti-slip layer
mounted increases friction. Furthermore, a large area of
support consisting of a flap and flap support increases its
resistance to mechanical damage. Also the simple system of
connection of individual elements of the support makes the
assembly and disassembly as well as replacement of
defective parts its easy.

of the container illustrating the floor with the flaps and
flap supports removed.
In the example of execution, the container for cargo
transport, especially coils, has a floor 1, two side walls
2, the front wall 3, two doors 4 and a removable rigid roof
5. Floor 1 is equipped with four pairs of folding supports,
which are arranged along its longer axis of symmetry. In
the open position, a pair of supports creates an inverted
isosceles trapezoid, which provides two or three points of
support for a cylindrical object. The floor has two pairs
of supports, each pair consisting of two rectangular flaps
6 opposite to each other, and two pairs of rectangular flap
supports 7. The supports are located on the shorter ends of
floor 1. Between them there are two pairs of supports, one
of which consists of two opposite, wide, rectangular flaps
8 and wide, rectangular flap supports 9, while the other
pair consists of two wide, rectangular flaps 8 and wide
rectangular flaps supports 10. Flaps 6 and wide flaps 8 are
connected to floor 1, along two lines, parallel to its
longer axis of symmetry, by hinges 11 located on one of
their edges. With the other opposite edge of flap 6 and
wide flap 8 they are connected to flap supports 7 and wide
flap supports 9 and 10, also by means of hinges. Each of
the flaps 6 and flap supports 7 has three hinges each 11,
whereas wide flaps 8 and wide flap supports 9 and 10 have
five hinges each 11. Flaps 6, wide flaps 8, flap supports 7
and wide flap supports 9 and 10 consist of a steel frame
made of channel sections on which a 5 mm thick flat steel
plate 28 is mounted. Throughout the length of floor 1, on
both sides of its centre of symmetry, there are two grooves
12. If the supports are closed, grooves 12 are covered by
flap supports 7, and wide flap supports 9 and 10. However,
when the supports are raised to create a trough, the edges

WO 2013/180586
PCT/PL2012/000093
7
of the flap supports 7, and wide flap supports 9, 10,
opposite to the edge with hinges 11, are placed in grooves
12. A single, open support takes the shape of a triangle
with three acute angles. Flaps 6 and wide flaps 8 are
covered with an anti-slip layer 13, which is made of
vulcanized rubber. Each of flaps 6 and wide flaps 8 has two
oval-shaped handles 14 located near the edge being in
contact with flap supports 7 and wide flap supports 9 and
10. Handles 14 make the lifting of a support easy. Roof 5
of the container has a mechanism fastening it to side walls
2, consisting of two locking bars 15, parallel to each
other, which are placed perpendicularly to the longer axis
Of roof 5. Locking bars 15 are mounted to the outer surface
of roof 5. The edges of roof 5 being in contact with side
walls 2, front wall 3 and beam 30 are equipped with sheet
rubber gasket 16 which seals slits and protects products
inside the container against adverse weather. On the upper
side of roof 5 there are two large handles 17. They are
located along the longer axis of symmetry of roof 5.
Openings of large handles 17 have a rectangular shape and
are parallel to the longer edges of roof 5. This
arrangement of large handles 17 makes it possible to
transport the roof with a forklift truck quickly. In
addition, on roof 5, there are four small handles 18. They
are placed at the longer side edges of roof 5 parallel to
the holes of big handles 17. This arrangement of small
handles 18 makes it the transport of the roof possible
using chains, ropes, or shackle ropes. At the upper and
lower edges of each side wall 2 there are small handles 18
eight pieces of which are placed at each of those edges.
Each door leaf 4 is identical in size and is equipped with
a closure consisting of two locking bars 19. In addition,
on the edges of door leaf 4 there is a sheet rubber gasket

CA 02874834 2014-11-26
WO 2013/180586
PCT/PL2012/000093

16, which seals slits and protects products inside the
container against adverse weather. On each leaf of door 4
there is latch hold 20. When door 4 is full open, latch
holds 20 are held by door holds 21, located on side walls
2. This prevents spontaneous closing of door 4. On each of
the side walls 2 there are two attachment mechanisms of the
roof 22, which are connected to locking bars 15 located on
roof 5. Disconnected attachment mechanisms of the roof 22
with locking bars 15 make disconnection of roof 5 from the
rest of the container possible- At the upper and lower
edges of each side wall 2 there are eight small handles 18.
On each side wall 2 there are two air holes 27, placed at
the upper corners. Floor 1 has seven small rectangular
hinged flaps 23 and two small hinged flaps 24. Small flaps
23 and 24 are mounted on strap hinges 25. Small flaps 23 in
relation to small flaps 24 are located on opposite sides of
the longer axis of symmetry of floor 1. Small flaps 23 are
obscured by, lying horizontally, flap supports 7 and wide
flap supports 9 and 10. Small flaps 24 are obscured by,
lying horizontally, wide flap supports 9 and 10. Floor 1
has two rectangular through holes 26 placed under the
usable layer. Holes 26 extend through the entire width of
floor 1, parallel to its shorter axis of symmetry. The
spacing of holes 26 is the same as the spacing of big
handles 17. Holes 26 make transport of the container with a
forklift truck possible. The structure of the container is
made of welded steel shapes. The usable layer of floor 1 is
made of 5 mm thick flat steel 28. The fill of the skeleton
structure of doors 4 is made of 4 mm thick flat steel 28
with moulded sections. The fill of the skeleton structure
of side walls 2, front wall 3 and roof 5 is made 2 mm thick
trapezoidal steel 29. Furthermore, the surface of roof 5,
on the area extending between its longer edges, where the

big handles 17 and small handles 18, are placed, is made of
flat sheet 28. Side walls 2 are connected to each other
above door 4 by means of removable beam 30. At each of the
corners of the container steel structure there are corner
fittings 31, so that the container can be moved by means of
container carriers and overhead cranes. In the example of
execution, the container is 20 feet long.
