Fluid storage container and lid thereof

Abstract

A fluid storage container includes a container body provided with an interior space for storing a fluid and an opening for guiding the fluid from the interior space to the outside. A lid covers the opening of the container and is provided with a discharge opening for the fluid. The discharge opening is configured so that the discharge opening is normally in a closed state, sealed by a plug, but is set to an open state when extracting the fluid from the container body. Thus, outside air and impurities are prevented from entering the container, which prevents the degradation of the contents of the container and thereby drastically increases the lifespan of the contents.

1 . A container for storing fluid material, comprising:
 a container shell that forms an internal space for storing fluids and a discharge opening guiding the fluids from the internal space to outside of the container; and   a lid that covers the discharge opening and prevents the fluids from being discharged to the outside of the container; wherein   the lid comprises a space connecting to the discharge opening of the container shell, an exit mouth on an opposite side of the lid from the discharge opening, a plug contacting with the exit mouth from inside the lid and located within the space for opening and closing the exit mouth, and a disk-form spring supporting the plug and arranged to move the plug from a closed position toward the discharge opening when an inner pressure of the container shell increases, and to move the plug from an open position toward the closed position when the inner pressure of the container shell decreases.   
     
     
         2 . The container of  claim 1 , further comprising:
 a stopper equipped in the lid for regulating movements of the plug.   
     
     
         3 . The container of  claim 1 , further comprising:
 a manually operative lever equipped in the lid and connected to the plug so as to allow either movement of the plug toward or away from the exit mouth.   
     
     
         4 . The container of  claim 3 , wherein the exit mouth is configured in a cylinder-like or conical shape so that the exit mouth protrudes away from the container shell. 
     
     
         5 . A container for storing fluid material, comprising:
 a container shell that forms an internal space for storing fluids and a discharge opening guiding the fluids from the internal space to outside of the container; and   a lid that covers the discharge opening and prevents the fluids from being discharged to the outside of the container; wherein   the lid comprises a thin film that forms a cylinder-form with one end connected to the discharge opening and the other end having an exit mouth for guiding the fluids from the discharge opening to the outside, the cylinder-form forming a flattened, closed position to prevent the fluids from being discharged through the exit mouth.   
     
     
         6 . The container of  claim 5 , further comprising:
 an inner bag arranged inside the container shell and having an internal space; and   a space between the inner bag and an inside surface of the container shell, wherein one of the space is linked to outside air or the internal space of the inner bag is linked to the outside air.   
     
     
         7 . (canceled) 
     
     
         8 . The container of claim  5 , further comprising:
 an absorbing material located near the exit mouth and equipped to absorb residuals of the fluids remaining around the exit mouth after the fluids are guided to the outside of the container.   
     
     
         9 . The container of  claim 5 , further comprising:
 a pump mechanism equipped to at least one of the lid or the container shell that helps increase pressure within the internal space of the container shell.   
     
     
         10 . The container of  claim 1 , wherein a surface of the lid is coated with an oxygen-proof thin film that is made of plastic or metal in order to prevent oxygen from entering the internal space of the container shell. 
     
     
         11 . A lid for a container shell for storing fluid material, the lid and container shell forming a container, the lid comprising:
 a space connecting to a discharge opening of the container shell, an exist mouth on an opposite side of the lid from a connection to the discharge opening, a plug contacting with the exit mouth from inside the lid and located within the space for opening and closing the exit mouth, and a disk-form spring supporting the plug and arranged to move the plug from a closed position toward the discharge opening when an inner pressure of the container shell increases, and to move the plug from an open position toward the closed position when the inner pressure of the container shell decreases.   
     
     
         12 . A lid for a container shell for storing fluid material, the lid and container shell forming a container, the lid comprising:
 a thin film that forms a cylinder-form with one end connectible to a discharge opening of the container shell and the other end having an exit mouth for guiding the fluids from an internal space of the container shell through the discharge opening to outside of the container.   
     
     
         13 . The lid of  claim 12 , further comprising:
 a bag for storing air inside that is engaged to a surface of the lid.   
     
     
         14 . The lid of  claim 11 , further comprising:
 a bag for storing air inside that is engaged to a surface of the lid.   
     
     
         15 . The container of  claim 2 , further comprising:
 a manually operative lever equipped in the lid and connected to the plug so as to allow either movement of the plug toward or away from the exit mouth.   
     
     
         16 . The container of  claim 2 , wherein the exit mouth is configured in a cylinder-like or conical shape so that the exit mouth protrudes away from the container shell. 
     
     
         17 . The container of  claim 1 , further comprising:
 an inner bag arranged inside the container shell and having an internal space; and   a space between the inner bag and an inside surface of the container shell,   
       wherein one of the space is linked to outside air or the internal space of the inner bag is linked to the outside air. 
     
     
         18 . The container of  claim 1 , further comprising:
 a pump mechanism equipped to at least one of the lid or the container shell that helps increase pressure within the internal space of the container shell.
