Hermetically sealed cosmetic compact case

A container body for storing makeup configured for selective movement between a first position and a second position, the container comprising:

• a base coupled to a cover by a hinge;
• a rim having a shape extending from the cover;
• a channel integral with and disposed between a first wall and a second wall of the base and having a shape corresponding to the shape of the peripheral rim;
• and
• at least one vent for reducing the air pressure in the container coupled to the seal;
• wherein, when the container is in the first position the rim is received by the channel such that air is discharged to the exterior of the container and provides a generally hermetic seal between the base and the cover.

A method of using a makeup container, comprising:

• providing a makeup container selectively positionable between a first position and a second position and having a base coupled to a cover by a hinge and including a cavity for holding a cosmetic substance comprising;
• placing the container in the first position;
• placing the cosmetic substance in the cavity;
• moving the container from the first position at least partially to the second position;
• discharging air from the cavity to the atmosphere;

• moving the container to the second position to provide a generally hermetic seal between the cover and the base.

A container for holding items, comprising:

• a cavity configured to receive the items;
• a generally hermetic seal for substantially partitioning the cavity from the environment selectively repositionable between a first position and a second position;
• and
• a vent for regulating the air pressure inside the cavity;
• wherein air is discharged from the cavity to the atmosphere when the seal is positioned from the second position to the first position and the cavity is substantially impervious to air from the atmosphere when the seal is in the second position.
