Abstract: A securing mechanism for releasible securement together of components and a latch member having at least one projection transverse of its axis, biasing means mounting the latch member on the first component for limited angular movement about its axis and biasing the latch member to a first angular position, a second component defining a bore to receive the latch member and defining one or more grooves extending along the bore to receive the projection to allow axial movement between the first and second components when the projection is in registration with the groove, and means defining a ledge adjacent the bore to receive the latch member to prevent relative axial movement between the components with the latch member in its first angular position. Manual movement of the latch member between its angular positions allows relative movement between components for separation.

Abstract: An upwardly open box is provided with an inset cover of substantial thickness perforated by a plurality of orifices adapted in size and spacing to the reception and retention of artist's crayons. The peripheral wall of the box, generally rectangular in plan, extends above the upper surface of the inset cover and protects the protruding ends of the crayons against breakage. The vertical location of the cover within the box is variable to accommodate to the changing length of the crayons with wear, by manually adjustable means including projections and recesses for removably securing the inset cover or holder plate in selected vertical positions relative to the box.
