PURPOSE: A vacuum enshrinement box is provided to prevent an air intake to the inside of the enshrinement box by sealing an insertion hole in which a silicon cap is inserted with an air curtain after discharging the internal air of the enshrinement box to outside with a vacuum pump through a contact surface of the silicon cap mounted in an air discharging hole. CONSTITUTION: A vacuum enshrinement comprises a body unit(10), an internal cover(20), a silicon adhesive, and an external cover(12). The body unit keeps the remains in the state of being sealed. The internal cover covers the top of the body unit and an air discharging hole(21) formed in an insertion hole(22) is blocked with a silicon cap(30) so that air in the inside of the body unit can be discharged to outside by using a vacuum pump. The silicon adhesive seals a contact surface in which the internal cover and the body unit are joined each other by a projected sill(11). The outer cover is joined to the top of the internal cover sealing the body unit. |
