Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a preservable food container having a refrigeration function together with an antibacterial and deodorizing function,

The present invention relates to a preservable food container having an antimicrobial and deodorizing function and a refrigerating function together with an antimicrobial and deodorizing function. More specifically, the present invention relates to a preservable food container having an antimicrobial and deodorizing function, The present invention relates to a preservable food container having a refrigerating function together.

Food containers may have features such as the ability to separate and use small quantities, the ability to move food, or the ability to store for a period of time. In particular, a food container having a cover or stopper may have the use of mobility or storage.

When the food is stored in the container, it is generally advantageous to have high airtightness because the food may be damaged by the bacteria. However, the sealing of the storage container generally has the disadvantage of increasing the manufacturing cost and increasing the weight or volume of the entire container, which is inconvenient for use. On the other hand, when food is stored in a container, maintaining freshness or taste is a major factor to be considered. Therefore, it is advantageous that the food containers with mobility or shelf life are simple to manufacture and use, so that the freshness or taste can be maintained during the storage period. In addition, it is advantageous that the food contained in the interior of the food container is kept at a low temperature. Therefore, it is advantageous that the food container itself has a refrigeration function.

As a prior art related to containers for improving the shelf life of food, there is Utility Model No. 1998-028253 'Closed structure of food container'. In the prior art, a round frame having a diameter capable of allowing the container to enter the inner bottom surface of the lid is projected downward in order to improve the sealing structure of the lid and to prevent the leakage of food, and to increase the freshness and taste of food according to far- And a cap having a plurality of micropores formed thereon is screwed to the round frame so that the far infrared ray emitting material is charged into the space formed therebetween, And a rubber packing with an outward protrusion formed between the round bottom surface of the container and the inner circumferential surface of the cap.

Another prior art related to food storage containers is Utility Model Registration No. 0211205, 'Food Storage Container'. The prior art aims at providing a container for storing foods and a anti-decay pack for preventing contents stored in a cover covering the container from leaking to the outside. In order to achieve the above object, the prior art is a food storage container comprising a body opened upward to store food therein and a lid capable of covering the body, wherein the container is made of ceramics for removing odor, charcoal, and deodorant Anti-corruption pack is integrally attached to the inside of the lid and is formed, and a plurality of through-holes are formed so that the space in the main body and the anti-corruption pack can communicate with each other.
