Abstract: A disk case comprises a case member having locking devices and elastic devices at an inner surface thereof. Each of the locking devices has an end thereof connected to the case member and the other ends thereof extended inwards and suspended. Each of the locking devices have an engaging block at the suspending end thereof, a locking flange at the top edge of the engaging block and an aperture beside the engaging block. Each of the locking devices is provided with two depressions at opposite sides of the aperture respectively to form two strips coupled with the engaging block. Each of the engaging blocks is provided with at least an elastic rib which has an end thereof connected to the inner side of the engaging block and the other end thereof projected inwards and downwards, and a button is located within the engaging blocks and is coupled with the distal ends of the elastic ribs.

Abstract: A snapping mechanism of a CD case, wherein, a short conic support area extending from the bottom of the case having at its center protruding a short cylindrical snapping member; a guiding concave and a conic guiding area respectively provided on top of and on circumference of the snapping member; individual snapping bulge provided beneath the conic guiding area; both the snapping member and the support area are equally divided into multiple sections by grooves for each section to be segregated into an elastic snapping panel, and a hollow channel provided to each of the snapping panels at where the snapping member connected to the support area for each elastic snapping panel and the support area to be connected by a trail.

Abstract: A disc box comprises a first box body and a second box body connected with one side of the first box body by a resilient connecting strip. A peripheral frame is upwardly and downwardly disposed along the other three sides of each the first box body and the second box body. A front face of the peripheral frame is formed with an inward recess. A pairs of holes corresponding to each other are formed on respective sides of the first box body and the second box body, respectively. The center portions of two sides of the first box body are formed with a male clip and a female clip, while the center portions of two sides of the second box body are also formed a female clip and a male clip.

Abstract: A disc box structure including a box body and a cover body pivotally connected with one side of the box body. An annular stepped projection is formed in the box body. The center of the annular projection is disposed with two opposite lifted engaging members. The lower ends of the engaging members are connected with the bottom face of the box body, while the upper ends of the engaging members are disposed with substantially semicircular opposite fitting ribs. An engaging projection is formed on an upper end of a middle section of the outer edge of each fitting rib. The inner edges of the opposite fitting ribs have several inward extending resilient bridge ribs which commonly connect with a pressing member, whereby-the engaging members have better structural strength and are protected from breaking due to shearing force of the disc. When it is desired to take out the disc, a user only needs to depress the pressing member between the engaging members to easily take out the disc.
