Description

[Detailed Description of the Invention] The present invention relates to a container ventilator that prevents corrosion, improves durability, and has a good appearance.

Conventionally, containers equipped with a ventilator have had the disadvantage that corrosion occurs more quickly in a part of the ventilator than in other parts.

In other words, in conventional containers, ventilators were fabricated from metal plates such as iron plates and attached to the main body or by welding with rivets, etc., which had the disadvantage that the corrosion protection of the inside or attached parts of the ventilator was incomplete. .

In detail, the corrosion prevention treatment for the inside of the container and the ventilator is specifically painting, but it is difficult to paint the inside of the container after welding the ventilator to the container. Even if the ventilator is welded after the welded part is painted and the paint is removed, the heat during welding burns the paint on the container side and inside the ventilator, resulting in a drawback that complete corrosion protection cannot be obtained.

In addition, some products are attached using rivets, etc., but the rivets are exposed to the outside, making them look unsightly, and if used for a long period of time, rainwater may seep into the container from the rivet attachment part, leading to corrosion. Ta.

Furthermore, although ventilators are generally provided with numerous small vent holes, it is difficult to completely paint the inner surfaces of the vent holes, which ultimately leads to accelerated corrosion.

The corrosion phenomenon from a portion of the ventilator was particularly severe in marine containers.

That is, as mentioned above, despite the incomplete corrosion protection treatment inside the ventilator, a large amount of salt-containing air enters and exits the sea container as the internal pressure of the container fluctuates.

The present invention eliminates the above-mentioned drawbacks, and it is difficult to apply anti-corrosion treatment, and the part that requires the most anti-corrosion treatment, that is, the ventilator, is made of plastic, and does not require rivets etc. for installation. Even when used, the rivet etc. are not exposed to the outside, the appearance is good, and the feature is that there is no intrusion of rainwater from the rivet attachment part.

Therefore, the ventilator of the present invention is constructed of box-shaped plastic and is attached to the container side using rivets or adhesive instead of welding.

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

FIG. 1 shows an exploded view of the container.

That is, sidewalls 2 are erected on both sides of the floor assembly 1, and furthermore, a front end assembly 3 is provided at one end, a rear frame assembly 4 and a door assembly 5 attached to the rear frame assembly 4 are provided at the other end. A roof assembly 6 is attached above.

As shown in the first figure, the ventilators 7 are provided above each of the marking areas 8 of the sidewall 2, and are configured to prevent rainwater from entering and only provide ventilation.

In detail, the plastic ventilator of the present invention is composed of a cover 9 and a mounting plate 13.

First, regarding the cover 9, the cover 9 is constructed in the shape of a tray, the opening edge 10 is directed toward the side wall 2 of the container, and the lower surface thereof is provided with a number of ventilation holes 11. In the example, the drain plate 12 that protrudes inward from the bottom of the interior is integrally molded of plastic.

Next, referring to the mounting plate 13, the peripheral edge of the mounting plate 13 is shaped to match the mouth edge 10 of the cover 9, and the mounting plate 13 has a shape that matches the opening edge 10 of the cover 9. A window hole 15 of a size that matches the ventilation hole 14 provided in the cover 2 is provided, and furthermore, in the embodiment shown in the drawings, when integrated with the cover 9, a window hole 15 is provided in the cover 9 at a position above the drain plate 12 of the cover 9. A drain plate 12 protruding from the top is integrally molded from plastic.

Further, if necessary, a groove 18 having a size that surrounds the ventilation hole 14 of the side wall 2 is provided on the side surface of the container of the mounting plate 13 so that an O-ring 17 can be inserted therein as necessary.

Note that the cover 9 is finally fitted and fixed to the periphery of the mounting plate 13, and the entire structure is finally formed into a box shape.

The ventilator 7 according to the present invention having the above structure is constructed by painting the side wall 2 of the container, and then attaching the mounting plate 13 using, for example, rivets 19 to the container side, specifically, the vent hole 14 of the side wall 2. The hole 15 is fitted and fixed, and then the lip 10 of the cover 9 is fitted around the mounting plate 13 and fixed with adhesive.

However, in advance, the cover 9 and the mounting plate 13 are assembled into a box shape, and the mounting plate 1 is attached using blind rivets or the like.
Three parts may be attached to the container side.

Note that the surrounding area is filled with a sealing material if necessary.

Therefore, there is no need for welding work, painting work for the welded parts, etc. as in the past, and there is no possibility of paint scorching caused by welding work.

Furthermore, there is no need for corrosion protection treatment of the ventilator 7 itself.
Corrosion from the vent hole 11 does not occur at all.

Furthermore, since the rivet 19 is not exposed to the outside, there is no possibility that rainwater will infiltrate into the container from the rivet attachment portion.

Furthermore, when molding the cover 9, it is possible to mold and display the user's mark, country name, address, container size, model, manufacturer's mark, etc., and these will not be erased and can be colored freely. This has an extremely aesthetic effect.
