Description

{REFRIGERATED CONTAINERS FOR FOOD STORAGE}

The present invention relates to a refrigerating container for food storage, and more particularly, to a refrigerating container for food storage, which comprises a container formed of a double wall structure, and a refrigerant portion in which an ice gel and a refrigerant are separated and arranged by partition walls, The present invention relates to a refrigerated container for storing food.

In recent years, consumption of bread and desserts has been steadily increasing due to westernization, diversification and busy daily life of diets. In line with this trend, the confectionery and bakery market has produced various finished products or semi-finished products such as hot dogs, toast, sandwiches, So-called "franchise-type" sales method is mainly used.

The characteristics of these confectionery baking franchises are that the company develops products, services, know-how, etc., and ensures that the system is smoothly circulated and operated. The franchisees are based on the products and systems developed by the head office, .

However, conventionally, the contents such as hot dog, toast, sandwich, vegetables and salads therein were firstly packed in a packaging container, then simply put in a plastic box and delivered to a store in a manufacturing factory using a refrigerator.

Therefore, due to the characteristics of breads and vegetables which are sensitive to temperature, there is a problem that freshness and quality such as discoloration due to exposure to room temperature or easy contact with the outside air due to drying and temporary storage are significantly deteriorated.

That is, in order to manufacture and sell high quality food having excellent taste and aroma as well as color, various conditions such as humidity, temperature, and time should be maintained in an optimal state according to the type thereof. Conventionally, It has been proved that rancidity is promoted by bacteria and enzymes during the process, resulting in a decrease in the flavor and texture of the food, and serious problems such as a high temperature on a hot day and a hot day on a hot day.

However, since such a styrofoam box is formed as a single unit, it is inconvenient to store because it is not used when it is not in use, and it is inconvenient to store the styrofoam box. Also, due to the inherent durability of the material, There is a disadvantage that the body is damaged when an external force or a load is applied in the loading process.

In addition, if a part of the body is broken, it can not be partially repaired or replaced. Therefore, the entire box must be disposed of, resulting in environmental pollution as well as a great economic loss.
