Claims
- 1. A container for storing makeup, the container comprising:a cover having a first interface, the first interface having a first periphery; a base for holding a cosmetic substance, the base having a second interface, the second interface having a second periphery corresponding to the first periphery; a generally hermetic seal providing a channel associated with the first interface and a peripheral rim associated with the second interface; and a discharge for reducing the air pressure integral with the first or the second interface; wherein the first interface and the second interface provide a substantially hermetic seal when the cover is closed with respect to the base and air is discharged from the container when the first interface engages the second interface.
- 2. The container of claim 1, wherein the channel is defined by a peripheral wall and the peripheral edge of the peripheral rim being received between the first periphery and the peripheral wall.
- 3. The container of claim 2, wherein the first periphery includes a bulge.
- 4. The container of claim 3, wherein the first periphery and the second periphery are circular shaped.
- 5. The container of claim 1, further comprising a housing coupled to the cover and the base, wherein the housing includes a cavity, the cavity allowing expansion of the cover or the base.
- 6. The container of claim 5, wherein the cavity is sized to permit expansion during loss-in-weight tests.
- 7. The container of claim 6, wherein the cover and the base are integral and joined by a hinge.
- 8. 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.
- 9. The container body of claim 8, wherein the rim is generally circular shaped.
- 10. The container body of claim 9, wherein the rim further includes a first sealing portion, a second sealing portion and a third sealing portion, and the channel further includes a first wall, a second wall and a third wall and at least one sealing portion is in direct contact with at least one wall to form the hermetic seal.
- 11. The container body of claim 10, wherein the vent is a generally square shaped recess in the channel.
- 12. The container body of claim 10, wherein the vent is a check valve.
- 13. The container body of claim 10, wherein the vent is a baffle provided in the cover configured for selective movement between a first and a second position in response to pressure exerted on the baffle.
- 14. The container body of claim 11, further comprising a generally circular shaped cavity configured to receive the makeup.
- 15. The container of claim 14, where the channel further includes an opening having a diameter less than the diameter of the rim.
- 16. The container body of claim 15, further comprising a housing for receiving the body and the cover.
- 17. The container body of claim 16, further comprising a second generally circular shaped rim extending from the cover configured to receive a mirror.
- 18. The container body of claim 17, wherein at least two sealing portions are in direct contact with at least two walls to form the hermetic seal.
- 19. The container body of claim 18, wherein the rim is integral with the cover.
- 20. The container body of claim 19, wherein the height of the rim is less than about 0.1 inches, the width of the rim is less than about 0.1 inches and the width of the vent is less than about 0.2 inches.
- 21. A makeup case for holding a cosmetic substance, the case providing a cavity contained by a cover and a base, the cover being selectively positionable between a first position and a second position, and configured to provide a generally hermetic seal between the cover and the base when the cover is in the first position, whereby the seal maintains the cover in the first position, the improvement comprising:a vent for regulating the air pressure inside the cavity; wherein when the cover is positioned from the second position to the first position air is discharged from the cavity to the atmosphere.
- 22. The improvement of claim 21, wherein the vent is a generally square shaped recess in the seal.
- 23. 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; and moving the container to the second position to provide a generally hermetic seal between the cover and the base.
- 24. The method of using a makeup container as recited in claim 23, further comprising compressing the center of the cover, lifting the edge of the base to evacuate air from the cavity and securing the base to the cover.
- 25. 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.
