PURPOSE: To prevent the inflow of harmful materials of external environment into a full-surface shaping body. CONSTITUTION: This hermetic holder has flat sealing bodies 2 and projecting parts 3 extending from these sealing bodies 2 and is integrally molded of flexible materials, such as silicone resins, polyurethane resins, polypropylene or nylon. The holder is formed with hole parts 4 penetrating through the projecting parts 3 from the sealing bodies 2. The peripheral edges of the full-surface shaping body comes into contact with the sealing bodies 2 when the full-surface shaping body is mounted on the head by inserting the temple parts 6 of spectacles 5 into the hole parts 4 and pressing the sealing bodies 2 to the temporas of the header of a user to be mounted with the full-surface shaping body. The inside surfaces of the sealing bodies 2 come into contact with the recessed parts formed by the temoras and the outside surfaces of the sealing bodies 2 come into tight contact with the inner peripheral edges of the full-surface shaping body. |
