Modern generation sealed compact case

A cosmetic compact, comprising in combination:

• a) a cylindrical base,
• b) a lid assembly comprising a window, and a hinge pivotally connecting it to said base, to enable the lid assembly to be moved between open and closed positions,
• c) said window having a downwardly facing, circular sealing surface,
• d) a substantially cylindrical platform member disposed between said base and said lid assembly, said platform member being captive therein and further being movable within limits in both a vertical and a rotary direction with respect to said base and lid assembly,
• e) said platform member further having an upwardly facing circular sealing surface adapted to seal against the sealing surface of the window,
• f) said base having an upwardly facing, semi-circular bearing surface against which said platform member can rest or alternately be manually turned within limits,
• g) said base further having a pair of upwardly facing cut-outs in said bearing surface,
• h) said platform member having two oppositely disposed radially extending bridges, extending outward through said cut-outs in the base,
• i) a pair of manually-engageable semi-circular actuator grip members on said bridges, respectively, and disposed at the exterior of said base so as to be accessible to the fingers of the user, and
• j) multiple cooperable camming devices on the platform member and lid assembly, responsive to turning of the grip members, to raise the platform member sealing surface against the window sealing surface and thereby improve the seal therebetween.

A cosmetic compact, comprising in combination:

• a) a base,
• b) a lid assembly and a hinge pivotally connecting it to said base, said lid assembly comprising a cover having an expansive central opening,
• c) said lid assembly further comprising a window fitted in said expansive central opening and sealingly engaged therewith,
• d) said window having a downwardly facing, circular sealing surface, and further having a plurality of depending radially inwardly facing latching lugs circumferentially spaced about the periphery of the window,
• e) a substantially cylindrical platform member disposed between said base and said lid assembly, said platform member being captive therein and further being movable within limits in both a vertical and a horizontal direction with respect to said base and lid assembly, and being turnable therein,
• f) said platform member further having an upwardly facing circular sealing surface adapted to seal against the sealing surface of the window,
• g) said base having an upwardly facing, semi-circular bearing surface against which said platform can rest or alternately be manually turned within limits,
• h) said base further having a pair of upwardly facing cut-outs in said bearing surface,
• i) said platform member having two oppositely disposed radially extending bridges, extending outward through said cut-outs in the base, respectively,
• j) a pair of manually-engageable substantially semi-circular actuator grip members on said bridges, respectively, and disposed at the exterior of said base so as to be accessible to the fingers of the user, and
• k) a series of circumferentially disposed cam ramps on the exterior of said platform member, said cam ramps having clearance spaces between them to receive the respective latching lugs of the window, whereby upon turning of the actuator grip members when the lid assembly is closed, the window latching lugs ride along the cam ramps to exert a force on the platform member in a direction tending to tighten engagement between said circular sealing surfaces on the window of the lid assembly and on the platform member, and thus reinforce a seal therebetween.
