  • Patent number: 5232001
    Abstract: A cosmetics compact having a shell-shaped housing lower part, a powder tray and/or insert containing the like inside the housing lower part and a lid coupled by way of a hinge, having matching pairs of hook-like detent elements for locking lid and housing lower part, with a first detent element being integrally formed in one piece on the lid, as well as having a presser for releasing the detent elements. The technical problem is reliable guidance of the presser over a long displacement path and high strength of the detent elements, also inexpensive manufacture and ease of operation for the user. The second detent element is seated in one piece on the housing lower part. The presser is connected via a V-shaped carrier to the insert and is rectilinearly guided in an opening in the housing lower part, and projections of the presser may be brought into engagement with the first detent element.
