1. A vacuum container, comprising:
a storage container having a container opening and an accommodating space communicating with each other, wherein the container opening is formed on a top portion of the storage container such that an object to be preserved passes through the container opening to get into the accommodating space;
a connecting tray component having a tray opening, a tray inside space and a guiding hole, wherein the tray opening is formed on a top portion of the connecting tray component and communicates with the tray inside space, the guiding hole is formed passing through the connecting tray component, and the connecting tray component air-tightly encloses the container opening to seal the accommodating space;
a top cap having a pressing part, wherein the top cap is flexible such that the top cap is pressed to collapse and deform, the top cap encloses the tray opening to seal the tray inside space in a manner that the pressing part is in a position corresponding to the tray opening of the connecting tray component, and the top cap has an exhausting hole passing through the top cap; and
two one-way exhausters, wherein one of the one-way exhausters is inserted in the guiding hole to mount in the connecting tray component thereby forming a tray one-way exhaust passage communicating the accommodating space of the storage container and the tray inside space of the connecting tray component, and another one-way exhauster is inserted in the exhausting hole to mount in the top cap thereby forming a cap one-way exhaust passage communicating the tray inside space and an outside space;
wherein when the pressing part of the top cap is pressed to collapse and deform toward the tray inside space, the tray inside space is compressed by the pressing part and exhausts an exhaust air through the cap one-way exhaust passage to the outside space, and then the accommodating space is driven by a pressure difference between the tray inside space and the accommodating space to exhaust through the tray one-way exhaust passage to the tray inside space so that the accommodating space becomes in a state approaching vacuum, and the pressing part resiliently recovers due to an intake air to the tray inside space.
