That is, the shock absorbing gap 9b having a rectangular cross section is formed by the main body of the hot water storage type hot water heater 1, the protruding support device 8b, the lower sleeve 7 and the mount 2.

FIG. 3 is a longitudinal sectional view schematically showing a convex support device according to Embodiment 1 of the present invention.
Next, the configuration of the convex support devices 8a and 8b and a method for connecting a set of sleeves will be described.

The convex support device 8a is formed by a projection in which an end portion on the middle layer sleeve 6 side of the upper layer sleeve 5 is folded, for example, in a crank shape.
The convex support device 8a includes an n-shaped fitting portion. The n-shaped fitting portion is formed by folding the end portion of the upper layer sleeve 5 on the middle layer sleeve 6 side inward, for example, in a crank shape.

The convex support device 8b is formed by a projection in which the end of the lower sleeve 7 on the side of the middle sleeve 6 is folded back into, for example, a crank shape.
The convex support device 8b includes a u-shaped fitting portion. The u-shaped fitting portion is formed by folding the end portion of the lower layer sleeve 7 on the middle layer sleeve 6 side inward, for example, in a crank shape.

Using the convex support device 8b configured as described above, the sleeves of a set of sleeves are connected.
That is, one end of the middle layer sleeve 6 is inserted into the n-shaped fitting portion of the upper layer sleeve 5.
Further, the other end of the middle layer sleeve 6 is inserted into the u-shaped fitting portion of the lower layer sleeve 7.
Accordingly, the middle layer sleeve 6 is fitted and fixed so as to be held by the n-shaped fitting portion of the upper layer sleeve 5 and the u-shaped fitting portion of the lower layer sleeve 7.

By the way, the hot water storage type water heater 1 has, for example, a tall shape in order to secure a hot water storage capacity in a limited installation space.
For this reason, in the case of transportation, the hot water storage type water heater 1 may be horizontally stacked on the loading platform of the transport vehicle. This is to reduce rolling and prevent collision with surrounding items.
However, when the hot water heater 1 is horizontally stacked on the carrier of the transport vehicle, for example, other articles may be stacked on the side surface of the hot water heater 1, and the hot water heater 1 may be deformed or damaged. .

  In the packing device according to the first embodiment, the convex support devices 8a and 8b are provided on a set of sleeves that cover the side surface of the hot water storage water heater 1, whereby the side surface (body portion) of the hot water storage water heater 1 is provided. It is possible to prevent deformation and damage due to external impact.

As described above, in the present embodiment, the protruding convex support device 8a provided to surround the hot water heater 1 on the inner surface side of the upper sleeve 5 and the lower sleeve 7 covering the hot water heater 1, 8b was provided.
For this reason, for example, during transportation, storage, and handling of cargo, an impact that is to be transmitted from the outside to the hot water storage type hot water heater 1 passes through a pair of sleeves, and then directly by the convex support devices 8a and 8b 1 can be prevented.
Therefore, the impact transmitted to the hot water storage type hot water heater 1 through the packing device can be reduced, and deformation and damage of the hot water type hot water heater 1 can be prevented.

Further, the convex support devices 8 a and 8 b are in contact with the hot water storage type hot water heater 1 to form impact buffering gaps 9 a and 9 b between the hot water storage type hot water heater 1 and the upper layer sleeve 5 and the lower layer sleeve 7. .
For this reason, for example, during transportation, storage, and cargo handling, an impact that is transmitted from the outside to the hot water storage type hot water heater 1 can be buffered by the impact buffering gaps 9a and 9b.
Therefore, the impact transmitted to the hot water storage type hot water heater 1 through the packing device can be reduced, and deformation and damage of the hot water type hot water heater 1 can be prevented.

The convex support device 8a is formed by folding the end portion of the upper layer sleeve 5 inward, and the convex support device 8b is formed by folding the end portion of the lower layer sleeve 7 inward.
For this reason, it is not necessary to use a new member or the like to form the convex support devices 8a and 8b, and the convex support is achieved with a relatively simple configuration without increasing the cost and deteriorating the packaging workability. Devices 8a, 8b can be provided.
Therefore, the packaging device which can reduce the impact transmitted to the hot water storage type hot water heater 1 through the packaging device can be obtained with a relatively simple configuration.

The convex support device 8a includes an n-shaped fitting portion formed by folding the end portion of the upper layer sleeve 5 inward, and the convex support device 8b folds the end portion of the lower layer sleeve 7 inward. The u-shaped fitting part formed in this way is provided. Then, the n-shaped fitting portion, the u-shaped fitting portion, and the end portion of the middle-layer sleeve 6 are fitted to connect a set of sleeves.
For this reason, it is possible to relatively easily connect the three-layer sleeves.
Moreover, the impact which the hot water storage type water heater 1 receives from the outside can be relieved by using the n-shaped fitting portion and the u-shaped fitting portion as the convex support devices 8a and 8b.
Furthermore, in order to form an n-shaped fitting part and a u-shaped fitting part, it can be simply configured without using a new component material.

  The set of sleeves is made of cardboard. For this reason, a packaging apparatus can be reduced in weight. In addition, disposal after using the packaging device can be simplified.

  In addition, since the end portions of the upper layer sleeve 5 and the lower layer sleeve 7 are folded back, for example, in a crank shape, the strength of the end portions of the upper layer sleeve 5 and the lower layer sleeve 7 is improved. Therefore, the impact transmitted to the hot water storage type water heater 1 through the packing device can be reduced.

  Further, since the convex support devices 8a and 8b are formed by folding back the end portions of the upper sleeve 5 and the lower sleeve 7 made of corrugated cardboard, the convex support devices 8a and 8b themselves have an elastic force, and are passed through the packaging device. Thus, the impact transmitted to the hot water storage type water heater 1 can be reduced.

  In the present embodiment, the convex support devices 8a and 8b are formed by folding the ends of the upper sleeve 5 and the lower sleeve 7 into a crank shape. However, the present invention is not limited to this, and the end of the middle sleeve 6 What is necessary is just to be able to fit a part, for example, arbitrary shapes, such as S shape, may be sufficient.

  In the present embodiment, the case where one set of sleeves has three layers has been described. However, the present invention is not limited to this, and an arbitrary number of sleeves may be used.
