Description

Food storage container

The present invention relates to a food storage container having a freshness maintenance function and a refrigerant member for supplying cool air to the inside of the container outside the container. The present invention provides a food storage container capable of maintaining the freshness of food stored in the container, .

Generally, a food storage container for storing and storing food such as vegetables, meats, and the like includes a container body having a predetermined volume, the upper portion of which is opened and food is received therein, and a container lid for opening and closing the opened upper portion of the container body do.

That is, the container lid is closed on the upper part of the container body containing the food, and then the container is sealed in a refrigerator or a separate storage place.

In order to maintain the freshness of food for a long time, the food should be stored in a storage container and sealed at a temperature of 0 to 4 ° C. In general households, the food is stored in a food storage container Store in refrigerator.

However, since the food storage container stored in the refrigerator is withdrawn at every meal, the temperature of the food stored in the food storage container is increased due to the room temperature higher than the refrigerator temperature, and the fermentation speed of the food is accelerated.

Generally, food storage containers made of a synthetic resin having characteristics that are cheap and light in characteristics, shape and color can be freely used are widely used.

However, the food storage container made of such a synthetic resin has a high airtightness, so that it is moved from a refrigerated storage place to a room temperature storage place, and when the external temperature is raised, the gas generated due to fermentation of the stored food can not be discharged to the outside.

In addition, when the outdoor storage is carried out for a long period of time by storing a plant storage container in a bag, there is a problem that the freshness of the food is deteriorated due to deterioration or decay of the food stored in the container due to an increase in the temperature inside the closed bag.

To solve this problem, food storage containers containing far-infrared rays or ceramics and food storage containers containing yellow loess have been devised and used.

Korean Utility Model Registration No. 20-0289837 discloses a structure in which an alumina powder such as yellow clay, elvanite, ilite, and jade or an original slab thereof is integrally formed in a fastening hole opened in a synthetic resin container, and deodorization, There is disclosed a food storage container which keeps the freshness of the fermented food in the container by a method of introducing air into and out of the far infrared ray and the microchambers formed in the member.

However, these food storage containers are insufficient to prevent the progress of fermentation of food due to external temperature changes.

Therefore, there is a demand for a food storage container capable of maintaining freshness for a long time even when the temperature changes outside.
