CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This Application is a Continuation of International
Application PCT/CN2014/085199, filed on Aug. 26, 2014. Application
PCT/CN2014/085199 claims the benefit of and priority to Chinese
Patent Application 201310464404.1 filed on Sep. 30, 2013.
BACKGROUND
[0002] The present invention relates to the technical field of
containers, and in particular to a container.
[0003] Presently, containers have become the most frequently used
means of transportation in international trade, however, the
containers also become a carrier taking the pests and other
microorganism during the goods transportation process. The pests
population brought into the territory by the container is very
difficult to thoroughly kill once its large-scale breeding occurs,
and the losses caused by the pests are also difficult to
assess.
[0004] The bottom frame of the container generally has its cross
members, bottom side rails and even the end sills configured in a
C-form configuration or a H-form steel structure, which
increasingly facilitating the carrying of the pests. When taking
into consideration the huge quantity of containers circulating
worldwide and the inbound and outbound speeds of the containers, it
is unpractical to require checking each of the containers to ensure
that it doesn't carry pests.
[0005] FIG. 1 shows a side view of the existent container, and the

cross member 2 of existent containers have their cross sections
approximately configured in a C-shape opening toward the side, and
the bottoms of the bottom side rail 1 and the cross member 2 are
open flat plates extending horizontally, where the pests and other
microorganism are often hidden. Due to the bottom side rail 1
capable of being directly observed from the outside of the

DETAILED DESCRIPTION
[0046] The description hereinafter gives a large quantity of
specific details so as to provide a thorough understanding of the
present invention. However, as obvious to the skilled in this art,
the present invention may be implemented without one or more of
these details. Some of the technical features well-known in this
art are not described in other examples so as not to confuse with
the present invention.
[0047] A detailed structure would be proposed in the following
description for the purpose of thorough understanding the present
invention. Apparently, the implementation of the present invention
is not limited to special details known by the skilled in this art.
The preferred embodiments of the present invention are described in
detail as follows, however, the present invention can also comprise
other embodiments besides these detailed description.
[0048] The embodiment of the present invention discloses a
container, the exterior structure of which is as shown in FIG. 4.
When cutting the bottom of the container of the present invention
in the C direction of FIG. 4, the sectional view shown in FIG. 5
can be obtained so as to observe the structure of the cross section
of the bottom side rail 30. As can be seen from FIG. 5, the
container of the embodiment of the present invention comprises a
floor 10, and bottom side rails 30 are provided at both sides of
the floor 10 and extend in the longitudinal direction of the
container. The cross members 50 are provided between the bottom
side rails 30 at both sides of the floor 10, and the cross members
50 are divided into two parts, that is, a part located below the
floor 10 as shown in FIG. 5, and a part located at the bottom of
the end face of the container (not shown in the figures), such
cross members 50 extend in the transverse direction of the
container. The bottom of each of the two end faces of the container
is provided with one cross member 50 respectively, while a
plurality of cross members 50 are provided below the floor 10,
these cross members 50 are separated from each other in the
transverse direction of the container, so as to provide support to
the floor 10. Then, cutting the bottom of the container of the
present invention in the D direction of FIG. 5 once again, it is
possible to obtain the sectional view as shown in FIG. 9 in which
the structure of the cross section of the cross member 50 can be
observed. The locations of the bottom side rail 30 and the cross
member 50 are generally at the bottom of the container.
[0049] To prevent the pests and microorganisms from hiding on the
cross member 50 of the container of the present invention, the
cross member 50 is configured to be a closed structure at least at
its bottom, or the cross member 50 extends in the vertical
direction at least at its bottom, and undoubtedly, the above two
manners can also be adopted simultaneously in one and the same
container to construct the cross member 50. The cross member 50
extending toward the ground in a non-bending manner at least at its
bottom specifically means that it extends toward the ground merely
in at least one direction and has no bending structure, for
example, the one direction along which it extends toward the ground
can form an angle of 70.degree., 80.degree. or other proper angle
with the ground, and such a direction can also be approximately
perpendicular to the ground (the angle formed with the ground is in
the range of perpendicularity tolerance for the angle of
90.degree..
[0050] With the container according to the embodiments of the
present invention, the underside of the cross member is free of a
location where pests and microorganisms are hidden, thereby
eliminating the possibility that the pests and microorganisms are
attached to the cross member and spreading everywhere with the
container, and meanwhile, the investigation of the container is
also simplified which contributes to increasing the speed of
circulation of containers.
[0051] Alternatively, to prevent the pests and microorganisms from
hiding on the bottom side rail 30, the bottom side rail 30 is
configured to be a closed structure at least at its bottom, or the
bottom side rail 30 is configured to extend toward the ground in a
non-bending manner at least at its bottom. Undoubtedly, the above
two manners can be adopted simultaneously to construct the bottom
side rail 30 in one and the same container. The meaning of the
bottom side rail 30 extending toward the ground in a non-bending
manner at least at its bottom may refer to the aforesaid
description about the cross member 50, its repeated description is
omitted here.
[0052] A description about the bottom side rail 30 and the cross
member 50 will be made in the following in conjunction with the
drawings.
[0053] Firstly, it can be seen from FIG. 5 that the bottom side
rail 30 employs an integrally closed rectangular tube. Such an
integrally closed bottom side rail 30 has no open structure in the
direction toward the transverse direction of the container, thus
eliminating the space where the pests and microorganisms can hide,
and moreover, such a square tube also has advantages of easy
processing, low cost and reliable support strength. In addition to
the closed rectangular tube, the bottom side rail 30 may also
employ a diamond tube known to the skilled in this art.
[0054] The cross member 50 shown in FIG. 9 is similar to the bottom
side rail 30 shown in FIG. 5, and also employs a rectangular tube.
Also, a diamond tube known to the skilled in this art is
practicable.
[0055] The bottom side rail 30 and the cross member 50 adopting a
closed structure can employ the above-mentioned closed structure of
standard shapes, such as the rectangular tube and diamond tube, but
as shown in FIGS. 6 to 8, the bottom side rail 30 and the cross
member 50 can also be configured, at their bottom, to be a closed
structure having at least one inclined side.
[0056] Referring now to FIG. 6, the bottom of the bottom side rail
30 is configured to be a closed triangular prism. Specifically, as
can be further seen from FIG. 6, the bottom side rail 30 comprises
a vertical plate 31, a horizontal plate 33 and an inclined plate
35. Here the vertical plate 31 extends in the vertical direction,
the horizontal plate 33 extends in the horizontal direction, and
the vertical plate 31 and the horizontal plate 33 are connected in
a L-shaped configuration so as to be supportive. Then the inclined
plate 35 is obliquely connected at the side edge of the horizontal
plate 33 and onto the surface of the vertical plate 31 to form a
closed triangular prism, thus the bottom of the bottom side rail 30
is closed and the pests and microorganisms are prevented from
entering. At the same time, the bottom side rail 30 of such a
structure has a smaller footprint while ensuring reliable support
strength.
[0057] Similar to the embodiment shown in FIG. 6, the cross section
of the bottom of the bottom side rail 30 can also be configured to
be a closed right-angled trapezoid as shown in FIG. 7. But it
should be noted by this time that the sloping side of the
right-angled trapezoid is required facing upward as shown in FIG.
7, so as to avoid the site where the pests and microorganisms could
hide.
[0058] Additionally, the bottom of the bottom side rail 30 can also
be configured into a closed triangular prism as shown in FIG. 8,
and by this time, the cross section of the triangular prism is an
approximate regular triangle with two inclined sides which
intersect and form a bump protruding in a direction away from the
cross member 50. Undoubtedly, the bottom of the bottom side rail
can also be configured as a polygonal prism of other forms.
[0059] The cross member 50 shown in FIG. 10 is similar to the
bottom side rail 30 of FIG. 6, the bottom of the cross member 50 is
configured to be a closed triangular prism. The specific formation
of the triangular prism may refer to the aforesaid bottom side rail
30. Furthermore, the bottom of the cross member 50 can also be
configured according to the right-angled trapezoid shown in FIG. 7,
but similarly, it should be informed that the sloping side of the
right-angled trapezoid is required to be provided above.
Alternatively, as shown in FIG. 8, it can also be configured to be
a triangular prism, the cross section of which is an approximate
regular triangle. Undoubtedly, the bottom of the cross member can
also be configured to be a polygonal prism of other forms.
[0060] According to the above-mentioned embodiments, the skilled in
this art can also reasonably predict other closed structures having
one or more inclined sides. But taking into consideration of
providing no site where the pests and microorganisms can hide, the
skilled in this art would provide the inclined side(s) at the upper
portion of the closed structure, rather than providing the
horizontal structure at the upper portion of the closed structure.
Also, taking into consideration of the volume restriction upon the
bottom side rail and the cross member as well as the fact that the
container needs to meet some design criteria, the skilled in this
art can reasonably provide the number of the inclined sides while
no excessive number of inclined sides will be arranged.
[0061] In the following, the cross member will be described by way
of example in conjunction with FIGS. 11 and 12, so as to explain
other embodiments of the bottom side rail and the cross member
having closed structure.
[0062] Referring firstly to FIG. 11, the cross member 50 shown in
FIG. 11 comprises epitaxial-plates 51 and an U-shaped support plate
53. Here, the U-shaped support plate 53 is in a U-shaped form in
cross section for supporting on the ground. There provide a pair of
epitaxial-plates 51, which are connected at both end at the opening
of the U-shaped support plate 53 and extend in directions away from
the U-shaped support plate 53. In this way, the cross member 50 can
also be approximately considered as an inverted .OMEGA.-form, being
applicable to the case where the floor 10 of the container has a
small ground clearance. Furthermore, the cross member 50 can also
have no epitaxial-plate 51, but only comprises the U-shaped support
plate 53 having an U-shaped cross section, and such a cross member
50 comprising only the U-shaped support plate 53 can be provided in
such a way that the U-shaped support plate 53 can open upward and
open downward.
[0063] Additionally, the bottom side rail 30 may also employ the
structure of the cross member 50 shown in FIG. 11, and employs the
embodiment in which only the U-shaped support plate 53 is comprised
and the U-shaped support plate 53 can open upward and open
downward. Only that in one and the same container, the bottom side
rail 30 and the cross member 50 adopting such a structure are
different in dimensions. As to the cross member 50, the
epitaxial-plates 51 are connected to the bottom surface of the
floor 10 by welding or similar process known to the skilled in this
art. As to the bottom side rail 30, the epitaxial-plate is used to
connect with the parts of the container above the bottom side rail
30.
[0064] When the floor 10 of the container has a small ground
clearance, the corrugated plate shown in FIG. 12 can also be used
as the cross member 50 (the corrugated plate is not applicable to
the bottom side rail), the corrugated plate comprises a plurality
of bumps joined side by side, and these bumps act to support the
floor 10. The use of a corrugated plate as the cross member 50 is
equivalent to integrating a plurality of cross members 50 into one
piece, and when being assembled, such a structure can complete its
connection with the floor 10 in only one step, simplifying the
assembling process. In practice, the corrugated plate can be an
ordinary side wall plate or an ordinary top wave plate.
[0065] As mentioned previously, the bottom side rail 30 and the
cross member 50 extend toward the ground in a non-bending manner at
least at its bottom, as an alternative embodiment, the bottom side
rail 30 and the cross member 50 are configured to extend vertically
toward the ground in a non-bending manner at least at its bottom.
Undoubtedly, in one and the same container, things can be that one
of the bottom side rail 30 and the cross member 50 is configured to
extend vertically toward the ground in a non-bending manner at
least at its bottom.
[0066] As can be seen referring to FIGS. 13 and 14, the bottom side
rail 30 comprises horizontal support plate 37 and vertical support
plate 39. Here, the horizontal support plate 37 is used to connect
with the parts of the container above the bottom side rail 30, and
the vertical support plate 39 extends vertically toward the ground
from the horizontal support plate 37 and is supported onto the
ground. There can be provided with only one or a plurality of
vertical support plates 39. For example, in FIG. 13, one vertical
support plate 39 is provided, which is connected to the end of the
horizontal support plate 37 so that the bottom side rail 30 is in a
form of an inverted L-shape (it can also connect onto the bottom
surface of the horizontal support plate 37 to form a T-shaped
bottom side rail). The vertical support plate 39 and the horizontal
support plate 37 can form at least one of a C-shape opening
downward, a T-shape, an inverted L-shape and the combination
thereof. In FIG. 14, two vertical support plates 39 are provided,
which are provided at two ends of the horizontal support plate 37
respectively, so that the bottom side rail 30 takes a C-shape
opening downward.
[0067] Furthermore, it is also possible that only the vertical
support plate 39 is used as the bottom side rail 30 without the
horizontal support plate 37 being provided. By this time, the top
of the vertical support plate 39 is connected with the parts of the
container above the bottom side rail 30, and the bottom of the
vertical support plate 39 is used to support on the ground.
[0068] FIGS. 15 to 17 illustrate another three embodiments of the
cross member 50, the three embodiments are similar in structure to
the bottom side rails 30 shown in FIGS. 13 and 14, the cross member
50 is also not configured to comprise a closed structure.
[0069] Referring firstly to FIG. 15, it can be seen that the cross
member 50 also comprises a vertical support plate 55 (being
equivalent to the vertical support plate 39 of the bottom side rail
30), the vertical support plate 55 connects below the floor 10 and
extends vertically toward the ground so as to act to support the
floor 10.
[0070] It is clear from FIGS. 16 and 17 that both of the two
embodiments comprise horizontal support plate 57 (being equivalent
to the horizontal support plate 37 of the bottom side rail 30), the
horizontal support plate 57 is connected to the bottom surface of
the floor 10 of the container by means of welding or similar manner
known to the skilled in this art, and the two kinds of cross
members 50 require at least one vertical support plate 55 being
comprised. FIGS. 16 and 17 illustrate exemplary embodiments in
which one vertical support plate 55 is adopted, wherein the
vertical support plate 55 of the cross member 50 of FIG. 16 is
connected at the central portion of the bottom surface of the floor
connecting plate 57, and extends toward the ground vertically, the
entirety of the cross member 50 forms a T-shaped structure. While
the vertical support plate 55 of the cross member 50 of FIG. 17 is
connected at the end of the floor connecting plate 57, and also
extends toward the ground vertically, the entirety of the cross
member 50 forms an inverted L-shape. Furthermore, according to the
structure of the bottom side rail 30 shown in FIG. 14, it is also
possible to provide one vertical support plate 55 at both ends of
the floor connecting plate 57 respectively, so that the cross
member 50 assumes a C-shape opening downward. Undoubtedly, the
bottom surface of the floor connecting plate 57 can also be
provided with a plurality of vertical support plates 55 arranged
side by side. The vertical support plate 55 and the horizontal
support plate 57 can form at least one of a C-shape opening
downward, a T-shape, an inverted L-shape and the combination
thereof.
[0071] Finally, reference is made to FIG. 18. FIG. 18 illustrates
that the cross members 50 of different embodiments are provided
below the floor 10, for example, the cross member 50 of a closed
structure can be provided at the part of the floor 10 subjected to
a large load, while the part of the floor 10 subjected to a small
load adopts the cross member 50 shown in FIGS. 15 to 17 for
supporting. FIG. 18 exemplarily adopts the above cross members 50
for supporting the floor 10 from below, but undoubtedly, as to
different situations, the skilled in this art also knows how to
select the cross members 50 of the above embodiments to support the
floor 10.
