A small food storage container comprising: a food storing body having a shape of a container having a food storing space in which gelled food is stored, the food storing space being changed in shape by means of the application of an external pressure to the food storing body and being returned to the original shape thereof by means of the release of the applied external pressure therefrom; a food filling body detachably mounted on the food storing body and having a shape of a curved cylinder having open top and bottom portions, characterized by one or more air inlets formed along the periphery thereof in such a manner as to allow the inside to communicate with the outside, and a food filling space formed at the inside thereof in such a manner as to communicate with the food storing space to fill the food there into; and a food opening/ closing part fitted to the inside of the food filling body and comprising an upper opening/closing member having a shape of a disc facing a lower opening/closing member having a shape of a disc to define the food storing space and the food filling space, wherein said upper opening/closing member serves to open and close the food filling space by means of suction and discharge pressures of air and wherein said lower opening/closing member serves to open and close the food storing space by means of the suction and discharge pressures of air, so that if the food storing space is compressed by the external pressure applied to the food storing body, the introduction of external air is closed by the discharge pressure generated from the food storing space, while the food stored in the food storing space is being moved to the food filling space, and if the food storing space is returned to the original shape thereof, the external air is introduced into the food storing space by the suction pressure generated from the food storing space, while the food filling space is being closed. a food storing body having a shape of a container having a food storing space in which gelled food is stored, the food storing space being changed in shape by means of the application of an external pressure to the food storing body and being returned to the original shape thereof by means of the release of the applied external pressure therefrom; a food filling body detachably mounted on the food storing body and having a shape of a curved cylinder having open top and bottom portions, characterized by one or more air inlets formed along the periphery thereof in such a manner as to allow the inside to communicate with the outside, and a food filling space formed at the inside thereof in such a manner as to communicate with the food storing space to fill the food there into; and a food opening/ closing part fitted to the inside of the food filling body and comprising an upper opening/closing member having a shape of a disc facing a lower opening/closing member having a shape of a disc to define the food storing space and the food filling space, wherein said upper opening/closing member serves to open and close the food filling space by means of suction and discharge pressures of air and wherein said lower opening/closing member serves to open and close the food storing space by means of the suction and discharge pressures of air, so that if the food storing space is compressed by the external pressure applied to the food storing body, the introduction of external air is closed by the discharge pressure generated from the food storing space, while the food stored in the food storing space is being moved to the food filling space, and if the food storing space is returned to the original shape thereof, the external air is introduced into the food storing space by the suction pressure generated from the food storing space, while the food filling space is being closed.
