Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a leak-free folding Q-folding box, and more specifically, it is used for the purpose of preventing external deformation, water intrusion, moisture, etc., and for storing items for a long period of time. Packaging for transporting items for preservation purposes, items that require water such as fish and shellfish, items that leak water such as vegetables, or equipment that must be transported waterproof. It concerns containers.

"Conventional technology" Conventionally, various packaging containers have been widely used.

In recent years, fish and other fish have also been transported alive, but I believe box-shaped containers made of synthetic wood I1W are used.

Empty boxes take up space to transport and store and are expensive, so they cannot be thrown away.An inexpensive box is a bag made of vinyl sheet or the like filled with water for transport.

``Problem to be solved by the invention'' However, plastic bags are easily damaged, tear during transportation, leak water, and are flexible, making them inconsistent in shape and difficult to stack during transportation and storage, making them difficult to use. This is causing some inconvenience.

"Means for Solving the Problems" Therefore, in view of the above-mentioned problems, the present invention has been made to provide a box as a packaging container that solves the conventional drawbacks. A hollow container with a desired shape is formed by folding the container in its original state.

That is, a rectangular bottom plate formed of a waterproof sheet and forming a bottom surface is provided with side wall forming portions in series on all sides (left, right, top and bottom), and the side wall forming portions are integrally formed between adjacent side wall forming portions. a box-shaped container with a bottom is formed by bending the intermediate connecting portions that are connected in series inward from the center, and a fold is provided in the center of the bottom plate, and a side wall is formed by extending the fold of the bottom plate. A continuous fold is also provided in the section, and the sheet is placed 71! on either the side wall forming section or the bottom plate where the fold is provided, from the four corners of the bottom plate corner toward the appropriate position of the central fold. It is a leak-proof folding box with folds that form a chevron shape when opened.

``Function'' Therefore, the sheets can be easily and quickly folded into a box-shaped container, and the box-shaped container can be folded into a flat shape from the center fold and stored stacked. By simply expanding the container, the desired hollow shape can be created. Therefore, if the container is filled with water and transported, it can be transported without water leakage, and after transport, the container can be folded into two at the fold. It can be folded and stored compactly.
