PROBLEM TO BE SOLVED: To prevent volatile components in a product from evaporating in an airtight container and preserve the product for a long period, by charging a material impregnated with the same component with the volatile component in the product in either container body or container cover body, in the airtight container covered with the cover body. SOLUTION: A container cover body 2 is put on the upper part of a container body 1 for a product 3 containing volatile components to secure the airtightness of the container body. When this container is applied for a lipstick, an immersed material 5 impregnated with the same volatile component with that in the product 3, is fitted in the inside of the container cover body 2. An interconnecting bubble type foamed body is preferable as the immersed material 5 but the raw material is not necessarily limitted to a special one and polyethylene or the like can be used. The concentration of the volatile component including in the immersed material 5 is set at a little higher level than the concentration of the volatile material in the product 3. In this way, the volatile material is evaporated first from the immersed material 5. As a result, the product can be protected for a long period. |
