Description

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

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shelf stable food container having an antibacterial and deodorizing function and improved preservability, and more particularly, to a shelf stable food container capable of enhancing shelf stability by imparting an antibacterial and deodorizing function to a cap of the container.

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.

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.

Although the prior art discloses a storage container using a anti-decay pack such as a divergence of far-infrared rays or charcoal, the freshness of the stored food is difficult to be practically achieved by such a method. Food spoilage is caused by various microorganisms that occur during the decomposition process of microorganisms, so it is necessary to use materials having antimicrobial or deodorizing components. It is also advantageous that the container itself is sufficiently sealed in the storage process to prevent inflow of microorganisms from the outside.

The present invention has been made to solve the problems of the prior art and has the following purpose.

It is an object of the present invention to provide a shelf stable food container having an antibacterial and deodorizing function in which at least a part of a food container is formed from an antibacterial and deodorant component.
