Patent ID: 7703627

Claim:
A vanity case which comprises a case body having a cavity, a lid that is coupled to a back section of the case body in an openable/closable manner, an inner plate that is received in an exchangeable manner in the cavity of the case body, and a slide piece that is housed in between the case body and the inner plate so as to be movable forwards and backwards, wherein the lid has an engaging claw piece formed hanging down on a front of its underside; the slide piece has an engaging arm protruding above that can engage with the engaging claw piece and is always biased elastically backwards; and the lid is always biased elastically toward opening of the case body, and wherein when the lid is dosed against the case body, the engaging claw piece of the lid engages with the engaging arm of the slide piece and thus the lid is in a closed position; when the slide piece is moved forwards, the engagement between the engaging arm of the slide piece and the engaging claw piece of the lid is released, thus opening the lid, characterized in that a rear end wall in a center of a rear of the case body is formed to be elastically deformable toward the front and two sides of the rear end wall are coupled to the case body so as not to move relative to the case body when the rear end wall is elastically deformed, and a rear end of the slide piece is placed opposite an inside surface of the rear end wall, whereby the elastic deformation of the rear end wall causes the rear end wall to engage and push on the slide piece to move the slide piece forward and release the engagement between the engaging arm of the slide piece and the engaging claw piece of the lid.
