Description

[Detailed description of the invention] The present invention relates to a door for a ventilated container, which has a ventilation mechanism, does not cause corrosion in the internal and external communication parts, is easy to manufacture, and is easy to attach a lining board. It is characterized by:

Ventilated containers are used for transporting perishable cargo such as fruits and vegetables that do not require refrigeration, as well as other grains, etc. Ventilation holes are provided at appropriate locations to communicate inside and outside, and these ventilation holes completely prevent rainwater from entering. In addition, the structure must be designed to prevent corrosion of the ventilation holes.

Preventing corrosion in the ventilation holes is particularly important when this type of container is mainly used for sea transportation and air containing salt enters and exits through the ventilation holes.

The above-mentioned antiseptic treatment specifically involves painting, but if the structure is designed to completely prevent rainwater from entering in advance, there is a drawback that internal painting is difficult.

In other words, if this type of container is made of metal and the internal and external communication parts are constructed by welding, etc., it will be difficult to paint the inside, and conversely, even if the internal and external communication parts are painted in advance, the internal coating will burn when welding with other parts. However, in the end, no corrosion protection effect could be obtained.

The present invention eliminates the above-mentioned drawbacks.

Next, referring to the installation of the lining board, the lining board is made of wood and is installed to provide a moisture absorbing effect to the inside of the container and further protect the cargo inside.

That is, in the case of a container made of metal, condensation may occur on the inner surface of the metal plate due to changes in the weather or internal cargo such as vegetables, fruits, grains, etc., and the internal cargo may be contaminated.

In order to prevent the occurrence of dew condensation as described above, and to protect the internal cargo in the event that the cargo collapses, a lining plate with a buffering effect is provided.

However, attaching a lining board to a door made of metal requires a lot of effort since nailing or the like cannot be done.

The present invention eliminates the above-mentioned drawbacks.

An embodiment of the present invention will be described in detail below with reference to the drawings.

In addition, in the illustrated embodiment of the present invention, the door has two levels of internal and external communication parts, but it may be configured in one level, or may be configured in three or more levels depending on the application.

FIG. 1 shows a front view of a ventilated container according to the present invention, FIG. 2 shows a right side view, and FIG. 3 shows a left side view.

That is, side panels 21 are attached to both sides of the floor assembly 20, a front end panel 22 is attached to one end, and an opening/closing door 1 is attached to the other end.
are provided, and a roof panel 23 is provided above them.
is provided. 24 in the figure is a corner post,
25 is a corner fitting.

In the case of the embodiment shown in the drawings, ventilation holes 26 are also provided above the side panel 21.

Although a detailed explanation of the ventilation holes 26 will be omitted, they have a structure that completely prevents rainwater from entering.

In addition, ventilation holes are provided in the front end panel 22 as necessary.

Next, the opening/closing door 1 of the present invention will be described. The details are shown in FIG.

The opening/closing door 1 is surrounded by a frame body 2 consisting of a square pipe-shaped upper frame 2a, side frames 2b, 2c, and a lower frame 2d, and a door plate 3 of an appropriate width is provided perpendicularly from the outer side of the lower surface of the upper frame 2a. , whose lower part is bent inward into a substantially U-shape, and a number of ventilation holes 3b are provided in the bottom surface portion 3a.

Further, a baffle plate 4 whose tip is inclined outwardly and downwardly is provided on the inner upright piece 3c to form two communicating parts.

In the case of the embodiment shown in the drawings, the baffle plate 4 is formed of plastic or the like, and at the same time, a fitting portion for the upright piece 3c is provided so that the baffle plate 4 can be fitted and completely fixed with an adhesive or the like.

Furthermore, a door plate 5 is provided on the inner side of the lower surface of the bottom surface portion 3a, which is once bent outwardly and bent, and further bent downward so as to be perpendicular to the vertical portion of the door plate 3.

Next, the lower end of the door plate 5 may be welded to the outer side of the upper surface of the lower frame 2d, but in the case of the present invention, an inner/outer communication part is further formed.

That is, the lower part of the door plate 5 is bent inward into a substantially U-shape, and a large number of ventilation holes 5b are provided in the bottom surface 5a, and the inner upright piece 5c is provided with a baffle plate 6 whose tip is inclined outward and downward. A communication section similar to the above-mentioned communication section is formed, and the lower inner side of the bottom surface section 5a is bent outward once and then bent downward so as to be perpendicular to the vertical sections of the door plates 3 and 5. A door plate 7 is provided, the lower end of which is welded to the outer side of the upper surface of the lower frame 2d.

In the present invention, the upper frame 2a, both side frames 2b, 2
A lining plate 10 having ventilation holes 8 and 9 provided above the baffle plates 4 and 6 is attached to the inner surface of the frame 2 consisting of the lower frame 2d and the lower frame 2d. The lining board 1
0 is blind rivet 1 as shown in the drawing example.
1 or attached to the inner surface of a square pipe-shaped frame 2 with screws or the like.

At that time, a mounting hole is drilled on the inner surface of the frame 2, but in the case of the present invention, even if powder, etc. falls into the pipe-shaped frame 2, the inside of the frame 2 will eventually become airtight. Corrosion is not promoted by cutting powder. Note that 12 in the figure is a sealing material.

The present invention having the above configuration includes a lining board 10 and a baffle board 4.
With the frame 2 and the door plates 3, 5, and 7 removed, the outer and inner surfaces of the frame 2 and the door plates 3, 5, and 7 are welded, and after the paint has dried, the baffle plates 4, 6, and the inner lining are removed. All that is needed is to attach the plate 10, and the interior and exterior communication parts can be completely painted, that is, completely anti-corrosion treated.

Furthermore, the construction of the interior and exterior communication portions is performed at the same time as the attachment of the lining plate, resulting in extremely easy manufacturing, making it ideal as a door for ventilated containers.
