BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates to a package. More particularly, it relates to a honeycomb
structure package capable of satisfactorily storing and transporting honeycomb structures
without breaking down the structures.
Description of the Related Art
[0002] At present, a package (a package box) for storing and transporting honeycomb structures
is made of a plastic material, a cardboard material or the like, and a cardboard box
is mainly used because it is lightweight and can easily be prepared at a low cost.
[0003] As shown in, for example, Figs. 9 and 10, a large number of stages of packages (package
boxes) are stacked during the storage and transport of the honeycomb structures. At
this time, a package box 18 has a configuration in which honeycomb structures 11 are
vertically disposed (the direction of through holes of the honeycomb structure is
a vertical direction) in through holes (each having a size equal to that of the laterally
sectional shape of each honeycomb structure 11 to be stored) in a positioning tray
16 disposed in the intermediate part of the package box 18 in a height direction thereof,
and the load of the upper package box 18 is supported by the honeycomb structures
11 (which are to be packaged) stored in the lower package box 18 (
JP-A-2003-112771).
[0004] However, in recent years, the size of each honeycomb structure has been increased,
and the product height (length) of the structure is increased to 30 cm or more on
occasion. In such a case, when the honeycomb structures are vertically disposed and
stored as in a conventional technology, the height of the package box increases. On
the other hand, there is usually a restriction on the height of a ship's hold, a warehouse
or the like used for the storage and transport. When the package boxes each having
a large height are stacked up to the above limited height, due to the limitation of
the height, the less number of stages of package boxes have to be stacked as compared
with the conventional technology. In such a case, there are problems that a dead space
increases, and the number of the honeycomb structures which can be stored in the ship's
hold, the warehouse or the like is limited, thereby lowering a transport efficiency.
[0005] To solve the problems, when the honeycomb structures are laterally disposed and stored
(the direction of the through holes of the honeycomb structures is a horizontal direction),
the height of the package can be prevented from being increased. However, the honeycomb
structure is characterized by having a high strength in a vertical direction (a direction
along the through holes of the honeycomb structure) and a low strength in a lateral
direction (a direction vertical to the through holes of the honeycomb structure).
Therefore, in a case where a large number of stages of packages containing the laterally
disposed honeycomb structures are stacked as in the conventional technology, when
the load of the upper package is supported by the lower honeycomb structures to be
packaged, the lower honeycomb structures might be damaged. In such a case, there is
a problem that eventually the stacking of the packages in a large number of stages
has to be avoided in order to avoid the damage of the lower honeycomb structures.
SUMMARY OF THE INVENTION
[0006] The present invention has been developed in view of such a problem of the conventional
technology, and an object thereof is to provide a honeycomb structure package which
does not have a very large package height even when containing products as compared
with the conventional technology, whereby the deterioration of a transport efficiency
can be prevented, and which can realize stacking in a large number of stages while
avoiding the damage of honeycomb structures.
[0007] As a result of intensive investigations for achieving the above object, the present
inventors have found that the following honeycomb structure package can achieve the
object, and have completed the present invention. That is, according to the present
invention, there is provided a honeycomb structure package as follows.
[0008]
- [1] A honeycomb structure package including: a plate base; a receiving member which
is disposed on the base to support the side surface portions of honeycomb structures;
and a rectangular parallelepiped box member constituted of five rigid panels which
surround the lower surfaces and side surfaces of the base and the receiving member.
[0009]
[2] The honeycomb structure package according to [1], wherein the box member has,
on the lower surface thereof, a connecting member having a shape complementary to
that of a space formed by the upper ends of the side surfaces of the box member, whereby
a plurality of box members are stacked.
[0010]
[3] The honeycomb structure package according to [2], wherein at least one of the
side surfaces of the box member is openable while an opening in the upper part of
the box member is closed.
[0011]
[4] The honeycomb structure package according to any one of [1] to [3], wherein the
receiving member has a receiving portion having a shape complementary to that of the
side surface portion of each honeycomb structure, and equally supports the side surface
portions of the honeycomb structures from the downside thereof.
[0012]
[5] The honeycomb structure package according to any one of [1] to [4], wherein the
receiving members are disposed on both the surfaces of the plate base.
[0013] According to the honeycomb structure package of the present invention, as compared
with a conventional vertical storage technology, the height of the honeycomb structure
package even when containing the honeycomb structures does not remarkably increase,
and the deterioration of a transport efficiency can be prevented. Moreover, when the
packages are stacked in a large number of stages, the load of the upper stage is not
carried by the lower honeycomb structures to be packaged, but is carried by the side
walls of the lower box member constituted of the rigid panels, which produces an effect
that stacking in a large number of stages can be realized while avoiding the damage
of the honeycomb structures.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] Hereinafter, an embodiment for carrying out the present invention will specifically
be described, but it should be understood that the present invention is not limited
to the following embodiment and can appropriately be design-changed or improved otherwise
based on the usual knowledge of a person with ordinary skill without departing from
the scope of the present invention.
[0017] Fig. 1 is an exploded perspective view for explaining one embodiment of a honeycomb
structure package according to the present invention. The honeycomb structure package
of the present invention includes a plate base 5; a receiving member 3 which is disposed
on the base 5 to support the side surface portions (on a lower side) of honeycomb
structures: and a rectangular parallelepiped box member 7 having five rigid panels
which surround the lower surfaces and side surfaces of the base 5 and the receiving
member 3. Here, the outer shape of each honeycomb structure 11 is formed by the inlet-side
end surfaces and outlet-side end surfaces of through holes of the structure and side
surface portions connecting the inlet-side end surfaces to the outlet-side end surfaces
of the through holes.
[1. Receiving Member]
[0018] In a honeycomb structure package 1 according to the present invention, the honeycomb
structures 11 are disposed on the receiving member 3 while the longitudinal direction
of each honeycomb structure 11 is set to a lateral direction (the honeycomb structures
are laterally disposed so that the direction of the through holes of the honeycomb
structures is a horizontal direction). There is not any special restriction on the
configuration of the receiving member 3 itself as long as the rotation or movement
of the honeycomb structures can be suppressed. The receiving member may be, for example,
a square frame made of the side surface (and the bottom surface if necessary) of a
rectangular parallelepiped member. For the sake of simplicity, an only longitudinal
support or guide (and the bottom surface of the member if necessary) may be used as
the receiving member to suppress the rotation of the honeycomb structures, and colliding
between the end surfaces of the adjacent honeycomb structures and/or between the end
surfaces of the honeycomb structures and the inner side surface of the box member
may be avoided by holding them with a buffer material or the like. Furthermore, as
shown in Fig. 2, the receiving member more preferably has a receiving portion having
a shape complementary to that of the side surface portion of the honeycomb structure
11, whereby the side surface portions of the honeycomb structures are equally supported
from the downside. The receiving member 3 is preferably secured to the base 5.
[0019] The receiving member 3 used in the present invention is preferably a sheet or foam
sheet made of a polyolefin-based resin, cardboard paper or the like having buffer
properties. Here, the polyolefin-based resin foam sheet is a foam sheet made of polyethylene,
polypropylene and a copolymer mainly made of olefin or the like. In particular, the
cardboard paper or the polyethylene resin foam sheet has an excellent elasticity,
and hence can suitably be used as the receiving member 3 used in the present invention.
[2. Base]
[0020] In the present embodiment, as shown in Fig. 1, eight honeycomb structures 11 are
disposed on the receiving member 3 provided on the base 5, and then two bases 5 are
stacked and stored in the box member 7. Fig. 3 is a partially enlarged view showing
the state of the stacked bases 5. As described above, the honeycomb structure has
less strength in the vertical direction as compared with the longitudinal direction,
but the weight of about one to ten honeycomb structures is sufficiently bearable.
[0021] As the base 5 used in the present invention, an inexpensive and lightweight material
having an appropriate rigidity is preferable. Examples of the preferable material
of the base 5 include cardboard, wood, iron, aluminum, copper and a polyolefin-based
resin. There is not any special restriction on the configuration of the base as long
as the honeycomb structures and the receiving member can be supported and a necessary
rigidity can be kept. The configuration of the base can appropriately be selected
from the group consisting of flat plate, corrugated plate, perforated plate and lattice
configurations.
[0022] Fig. 4 is a diagram showing another embodiment of the present invention, and is a
partially enlarged view from the side surface side, showing that two sets of honeycomb
structures, receiving members and bases are stacked in a case where the honeycomb
structures are laterally disposed on the receiving members. As shown in Fig. 4, an
elastic sheet 13 is sandwiched between the lower honeycomb structures 11 and the upper
base 5 in one example of the preferable embodiment of the present invention. Examples
of a material of the elastic sheet 13 include cardboard paper and a polyolefin-based
resin.
[0023] Fig. 5 is a diagram showing still another embodiment of the present invention, and
is a partially enlarged view from the side surface side, showing that two sets of
honeycomb structures, receiving members and bases are stacked in a case where the
honeycomb structures are laterally disposed on the receiving members. As shown in
Fig. 5, the receiving members 3 are provided on both surfaces of the upper base 5
to protect the lower honeycomb structures in one example of the preferable embodiment
of the present invention. It is to be noted that as a modification of this embodiment,
instead of providing the receiving members 3 on both the surfaces of the base 5, two
bases 5 each having the receiving member 3 on the only one surface thereof are used,
and the surfaces of the bases which are not provided with the receiving member 3 are
stacked with each other, whereby a similar effect can be realized.
[0024] Separately prepared receiving member and base may be combined and bonded if necessary,
but when the receiving member and the base are made of the same material of a resin
or the like, they may integrally be formed.
[3. Box Member]
[0025] The box member 7 in the present invention surrounds the lower surfaces and side surfaces
of the bases 5 and the receiving members 3. The box member 7 is constituted of five
rigid panels, and has a rectangular parallelepiped shape provided with an open upper
surface. As shown in Fig. 6, the box members 7 of the present embodiment may vertically
be stacked via connecting members 9. It is to be noted that the connecting members
9 will separately be described in detail. Moreover, as shown in Fig. 7, the box members
7 are preferably stacked so that at least one side surface of the box member can be
opened while an opening in the upper part of the box member is closed. Fig. 7 is a
diagram showing that the side surface of the second box member 7 among three stacked
box members 7 is opened.
[0026] Such a constitution can specifically be realized as follows. Hinges are attached
to the lower end of the rigid panel forming at least one side surface of the box member
and the corresponding portion of the rigid panel forming the bottom surface of the
box member, and the rigid panel forming the side surface of the box member is rotatable
around the hinges. In this case, when engaging means and engaged means are provided
around the upper end of the rigid panel forming the side surface and in the corresponding
position of the adjacent rigid panel, respectively, the side surface can be opened
only when necessary.
[0027] In another preferable example of the embodiment of the box member 7, the box member
can be folded so as to superimpose the side surface on the bottom surface and can
be made compact when the honeycomb structures are not stored. Such a constitution
can be realized, for example, by disposing engaging means and engaged means between
the adjacent side surfaces and disposing a hinge between each side surface and the
bottom surface.
[0028] There is not any special restriction on the size of the box member 7. However, the
bottom surface of the box member 7 preferably has such a size that two to four honeycomb
structures are arranged in the longitudinal direction of the honeycomb structures
and that about two to eight honeycomb structures are arranged in the direction vertical
to the longitudinal direction of the honeycomb structures. Moreover, the box member
7 preferably has such a height that about two to four honeycomb structures disposed
so as to have through holes in the horizontal direction thereof are stacked.
[0029] There is not any special restriction on the material of the rigid panels of the box
member 7. A net-like material made of a metal such as iron, aluminum or copper is
a preferable material because the material has a sufficient rigidity and is lightweight.
There is not any special restriction on the configuration of the rigid panels constituting
the box member 7 as long as contents do not jump out of the box member but are stored
therein and a necessary rigidity can be kept. The configuration of each rigid panel
can appropriately be selected from the group consisting of flat plate, corrugated
plate, perforated plate and lattice configurations.
[4. Others]
[0030] The connecting member 9 is disposed under the box member 7. This connecting member
9 has a shape complementary to that of a space formed by the upper ends of the side
surfaces of the box member 7, and has such a function that any deviation is not generated
among stacked box members in a case where the plurality of box members 7 are vertically
stacked. Moreover, when one box member is used alone, this connecting member 9 has
a function of legs of the box member 7. There is not any special restriction on a
material of the connecting member 9, but the same material as that of the box member
7 may be used.
[0031] Moreover, when a plurality of vertically stacked honeycomb structures are stored
in the box member 7, an intermediate tray for stacking may be disposed between the
lower honeycomb structures and the upper base 5.
[0032] Fig. 8 is a diagram showing a modification of the present invention. In Fig. 8, engaging
members 15 are disposed on the corresponding portions of at least a pair of panels
facing each other among rigid panels constituting side walls of a box member 7. The
engaging members 15 are members which can engage the bases 5 with the rigid panels.
The bases 5 are supported by the rigid panels via the engaging members 15. It is to
be noted that the engaging members 15 may not be disposed on the side of the rigid
panels, but may be disposed on the side of the bases 5. According to such a constitution,
when the plurality of honeycomb structures are vertically stored in the box member
7, it is possible to obtain an effect that any load of the upper honeycomb structures
or the like is not applied to the lower honeycomb structures. Moreover, an effect
of eliminating the instability of the stacking can be produced. Furthermore, the intermediate
tray for stacking or the like may not be used.
[0033] A buffer member or the like may be disposed between the box member 7 and the honeycomb
structures 11 or the like. According to such a constitution, even when the rigid panels
constituting the box member 7 directly come in contact with the honeycomb structures
during transport or the like, the honeycomb structures can be prevented from being
damaged. Moreover, dust or the like can be prevented from adhering to the honeycomb
structures during storage. There is not any special restriction on a material of the
buffer member, and a generally broadly used buffer material such as a polyolefin-based
resin may be used.
[0034] To prevent the dust or the like from adhering to the honeycomb structures during
storage, the outside of the box member 7 may be stretch wrapped in one of preferable
embodiments.
[0035] As described above, the package of the present invention can satisfactorily store
and efficiently transport the honeycomb structures as products which easily break
down, and has a large industrial utility value.
