    摘要: A vanity case includes a receptacle and a cover hinged with each other at rear ends thereof, the cover being maintained in a closed position by engagement between latch tongues formed on the receptacle and the cover. The receptacle is formed at the front end with a recess within which is slidably disposed a push piece having a front wall and an arm integrally formed with the front wall through a thin flexible section which permits the arm to tilt relative to the front wall. The upper end of the arm is positioned closely adjacent the lower surface of the cover, and the rear end of the arm abuts against the inner wall defining the recess and, upon rearward movement of the push piece, slides on the inner wall upwardly to tilt the arm whereby the upper end of the arm forces the cover in upward and forward directions to release the engagement of the latch tongues.
