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.
Claims18
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.

- 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.
(canceled)
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.
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.
