Description

Packing sacks having heat and cold insulation function}

The present invention relates to a packaging bag for heat preservation and cold storage in which the bottom surface of an internal space is formed in a quadrangular shape when unfolded, and more particularly, is formed in a folding structure to enable easy folding, When unfolding to pack products in the inner space, the bottom surface of the inner space is formed in a square shape with four corners, thereby maximizing the internal volume and at the same time reducing the volume before unfolding. The present invention relates to a packaging bag for heat preservation and cold storage in which the bottom surface of an inner space is formed in a square shape when unfolded to maximize ease of storage, loading, transportation, and unloading.

Like a normal gift set, a packaging box used for packaging and distributing the contents is largely made of paper and a foamed resin material called Styrofoam. It can display explanations and advertisements, but its use was inevitably limited because it could not be kept warm and cold at an appropriate temperature for the contents in the distribution process.

Therefore, the packaging box made of paper has a problem in that it cannot be delivered to consumers by courier or other means of transport, containing living things such as agricultural products or marine products and processed products that require heat preservation or cold storage, due to insufficient heat retention, cold insulation, waterproofing, and moisture proofing. there is.

In addition, in the case of a foamed resin box, there is an advantage of being able to store and distribute the contents by warming and cooling at an appropriate temperature, but, like a paper box, it is inevitably limited to printing various descriptions and advertisements on the surface Due to the problem that the volume increases because the molded box cannot be folded and must maintain the circular size, it takes up a considerable space during delivery, resulting in increased logistics costs, storage, and storage.

In addition, due to the nature of Styrofoam being easily melted when volatile substances come in contact with it, it was impossible to express the contents of the product on the surface of the product or to show the effect of explanation and advertisement. Therefore, durability is weak, such as easily crumbling even with a slight impact, and there are problems such as collection logistics cost.

On the other hand, since the packaging bag is not in the form of a box, it is used when storing products inside the outer box. However, it is inconvenient and takes a lot of time to unfold the bag and pack the product, and unnecessary space is required between the outer box and the packaging bag. As this increases, the internal space is reduced, and the problem of not being able to maximize the effect of keeping warm and cold has occurred.

That is, there is a need for a new style of packaging bag for keeping warm and cold, which can further improve the effects of keeping warm and cold by reducing unnecessary space between the outer box and the packaging bag and minimizing the gap due to its box shape.

Therefore, the present invention can solve the above-mentioned conventional problems,

It is formed in a folding structure so that it can be easily unfolded and stored, but when unfolded, the bottom surface of the inner space is formed in a square shape to maximize the internal volume for storing products. To promote, and form a separate extended surface that is folded on one side or the lower surface of the bottom surface to improve the effect of mitigating external shock and warming or cooling the product packed in the inner space, and inserting it inside the outer packaging box, When positioned and used together, the remaining space (wasted space) of the inner space of the outer packaging box due to the insertion of the packaging bag is eliminated, so that the inner volume of the outer packaging box as well as the remaining space (wasted space) is eliminated. ), it is intended to provide a packaging bag for heat preservation and cold preservation, in which the bottom surface of the inner space is formed in a square shape when unfolded, maximizing the effect of heat preservation and cold preservation.

In other words, since it is in the shape of a square box, unnecessary space between the outer box and the packaging sack is reduced and the gap is minimized, thereby maximizing the internal volume and further improving the effect of keeping warm and cold. Therefore, it is intended to provide a packaging bag that provides convenience in handling, reduced logistics costs, and reduced storage space by reducing the volume of the packaging bag.
