Description

Fish box{FISH BOX}

The present invention relates to a fish box, and more specifically, to prevent the fish box from being distorted or sagging due to the weight of the fish contained therein, as well as to prevent damage to the fish located below when stacked in multiple stages, This relates to a fish box that improves convenience by improving the drainage flow to facilitate water drainage.

A fish box is made in the form of a rectangular box with an open top, and is used to store (or transport) fish and shellfish such as fish and shellfish by forming an empty space inside them.

These fish boxes have been widely used for a long time and can be made using a variety of materials, with fish boxes made of wood being the most widely used.

However, in the case of fish boxes made of wood, the weight of the wood itself is considerable, and when moisture or humidity seeps in, it becomes heavier, so it takes a lot of force to transport it. If an external force or load is applied, it can easily break at the joint or the tree. The product itself may be damaged, causing significant inconvenience during transportation.

In addition, due to the nature of the wooden fish box, bacterial growth occurs easily due to the fish, shellfish or seawater stored inside, and it is not easy to clean, which can be unhygienic.

For reference, storing empty boxes by stacking them in multiple layers in the top and bottom direction is called nesting. When wooden fish boxes are stacked in multiple layers, there is no or very little overlap, so they take up a lot of space, reducing space efficiency and cost. It may be inefficient in some respects.

To solve these concerns about damage and sanitary disadvantages, fish boxes are recently being replaced by fish boxes made of plastic materials.

Plastic fish boxes are made by injection molding plastic material so that they are not easily damaged by external impacts. The bottom and sides have a predetermined thickness, holes for drainage are formed on the entire bottom and sides, and the bottom is not prone to distortion of the fish box. Grid structure ribs are formed to prevent sagging.

The plastic fish box according to the prior art is an improvement over the wooden fish box, but in the process of storing or transporting multiple fish boxes stacked up and down, the rib structure on the bottom causes the fish and shellfish located at the bottom of the bottom to be pressed. Since problems with damage occur frequently, improvement is required.

The technical configuration described above is background technology to aid understanding of the present invention, and does not mean that it is a conventional technology widely known in the technical field to which the present invention pertains.
