Abstract
Abstract A compact case employs a 360°, double-pin hinge which pivotally connects a lid and a base of the compact case in such a manner that the lid can be tucked away behind the base for display and packaging purposes. Before the lid is closed for the first time, the hinge is permanently locked into a position which converts it into a 180°, single-pin hinge.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
185 words
A compact case, comprising a base; a lid; hinging means for hinging said lid to said base such that said lid is movable relative to said base between a first position in which said base and said lid are arranged generally back to back and a second position in which said base and said lid are arranged generally face to face, said hinging means including a hinge member pivotable relative to said base about a first pivot axis and pivotable relative to said lid about a second pivot axis, said first and second pivot axes being positioned relative to each other such that said hinge member is movable between an unlocked position, which said hinge member assumes when said lid is in said first position, and a locked position, which said hinge member assumes when said lid is in said second position; and locking means for automatically and non-releasably locking said hinge member in said locked position in response to the pivotal movement of said hinge member relative to said base as said hinge member is moved from said unlocked position to said locked position.
Claim 2
Dependent Claim
185 words
A compact case, comprising a base; a lid; hinging means for hinging said lid to said base such that said lid is movable relative to said base between a first position in which said base and said lid are arranged generally back to back and a second position in which said base and said lid are arranged generally face to face, said hinging means including a hinge member pivotable relative to said base about a first pivot axis and pivotable relative to said lid about a second pivot axis, said first and second pivot axes being positioned relative to each other such that said hinge member is movable between an unlocked position, which said hinge member assumes when said lid is in said first position, and a locked position, which said hinge member assumes when said lid is in said second position; and locking means for automatically and non-releasably locking said hinge member in said locked position in response to the pivotal movement of said hinge member relative to said base as said hinge member is moved from said unlocked position to said locked position.
Claim 3
Dependent Claim
57 words
A compact case according to claim 1, wherein said second pivot axis is positioned on one side of said first pivot axis when said hinge member is in said unlocked position and wherein said second pivot axis is positioned on an opposite side of said first pivot axis when said hinge member is in said locked position.
Claim 4
Dependent Claim
28 words
A compact case according to claim 1, wherein said lid cannot be moved to said second position until said hinge member has been moved in said locked position.
Claim 5
Dependent Claim
47 words
A compact case according to claim 1, wherein said locking means includes first latching means provided on said base and second latching means provided on said hinge member, said first and second latching means cooperating with each other to lock said hinge member in said locked position.
Claim 6
Dependent Claim
101 words
A compact case according to claim 4, wherein said first latching means includes at least one cutout provided in an upper edge of said base and wherein said second latching means includes at least one projection provided on a surface of said hinge member which is remote from said base when said hinge member is in said unlocked position and which is proximate to said base when said hinge member is in said locked position, said at least one projection having engaging means for permanently engaging said base while said at least one projection extends through said at least one cutout.
