Abstract:
1. A vanity case, comprising: a case body for containing a cosmetic material; a lid for opening and closing an upper surface of the case body; a first hinge piece and a second hinge piece, each of the first hinge piece and the second hinge piece being formed in one of the case body and the lid; a hinge block formed in the other one of the case body and the lid and arranged between the first and the second hinge pieces; a hinge pin inserted through the hinge block and one of the first hinge piece and the second hinge piece to pivotably couple the lid with the case body; and a friction member formed in the shape of an O-ring and made of a rubber material or a synthetic resin material, the friction member being elastically deformable, wherein a torsion spring is provided at the first hinge piece side of the case and engaging the case body and the lid for urging the lid to rotate in an opening direction; wherein a convex portion is formed in one of the second hinge piece and the hinge block facing the second hinge piece; wherein a concave portion is formed in the other of the second hinge piece and the hinge block facing the second hinge piece so that the convex portion can be inserted therein; wherein the friction member is provided in the concave portion to brake the rotational speed of the lid due to the torsion spring by holding the friction member under pressure between the concave portion and the convex portion; wherein a protrusion is provided on one of an outer circumference of the convex portion and an inner circumference of the concave portion for braking the rotational speed of the lid by sliding contact with the other one of the outer circumference of the convex portion and the inner circumference of the concave portion; and wherein a recessed circumferential portion is formed between the outer circumference of the convex portion and the inner circumference of the concave portion so as to release the sliding contact of the braking protrusion at least at the closed position of the lid.
