  • the compact disc or CD itself is designated by numeral 10
  • the customary cover sheet or name plate that goes into the top of the package above the disc is designated 12.
  • Numeral 14 indicates a pamphlet or book of instructions or other information about the recorded contents of the disc, and/or the manner in which the product and/or package should be used.
  • the package as a whole is indicated by numeral 18. The structure of the individual parts of the package will first be described, then the method of assembling the various parts to form the completed package will be described, and thereafter the method of storing or ejecting a CD will be explained.
  • Principal component parts of the CD case 18 are a top plate assembly 20, a bottom plate assembly 30, and a spring support assembly 40, each of which is an integrally formed plastic part having many important features .
  • a separate part is the dust wiper or broom 60, which protects the bottom side of the CD from dust.
  • the assembled package is normally open on its forward end, once the shrink-wrap plastic cover has been removed .
  • Top plate assembly 20 has a top wall 21 and parallel left and right side walls 22, 23, which depend downwardly from the top wall .
  • a spring retainer rib 24 also depends downwardly from the top wall 21, and extends transversely along a portion of the rear edge of the top wall, as best seen in Fig. 1.
  • the lower front edge of spring retainer rib 24 is curved upwardly at 25, as best seen in Figs. 2 and 3.
  • the side walls 22, 23, have a pair of upper grooves 26 on their inner surfaces adjacent top wall 21, which are adapted to slidably receive the name plate or cover sheet 12.
  • a pair of lower grooves 27 in the side walls are further from the top wall 21 and are adapted to receive the CD itself .
  • Two pairs of protrusions or bumps 28A and one pair of protrusions or bumps 28B in respective ones of the lower grooves 27 are important in inserting, storing, or removing the Cd from the case, as later discussed.
  • Farthest from the top wall 21 there are small ribs or tongues 29 formed on the inner sides of the side walls 22, 23, which are used in assembling the parts of the case together.
  • Top plate assembly 20 does not in fact include any kind of a "plate”, and that term is used only as a convenient means of differentiating it from the individual "wall” structures. It is necessary for the material from which assembly 20 is formed to have a certain amount of flexibility, as later described.
  • Bottom plate assembly 30 is also an integrally formed plastic part, with two folded layers including a lower bottom wall 31 and an upper bottom wall 32.
  • Upper bottom wall 32 has a rearward extension 33, with a first portion 33a being angled somewhat downwardly and a second portion 33b being essentially coplanar with the lower bottom wall 31 (see Fig. 5) .
  • Extension portion 33b has small grooves 34 on its outer side edges, as seen in Fig. 1 in perspective and in Fig. 5 in cross-section.
  • a back end wall 35 At the rearward extremity of the rearward extension 33 is a back end wall 35, which rises perpendicularly upward from extension portion 33b, as seen in Figs. 1 and 5.
  • the upper bottom wall 32 is partially cut away to save material, leaving a central section in the form of an X.
  • the width of both the lower bottom wall 31 and the upper bottom wall 32 appears to be less than the width of extension 33b, but those widths are in fact equal, as clearly shown in Figs . 6 and 7.
  • Spring support assembly 40 is preferably formed as an integral plastic member and includes both a spring support member 41 and the spring member 50.
  • Support member 41 has a top wall 42 the length of which is equal to the external width of the top plate assembly 20 measured between the outer surfaces of the side walls 22, 23.
  • Support member 41 also has a vertical rear wall section 43 that extends downwardly from the rear edge of top wall 42, and whose length is the same as that of the top wall.
  • Top wall 42 has a bendable section B, forming a button B that may be used to release the ejection spring.
  • the material of the plastic top wall is preferably cut on two sides and one end, leaving the remaining end as a hinge for the button B. See Fig. 1, 2, 5, and 7.
  • Spring member 50 has a fixed end 51 which protrudes outwardly from and is securely affixed to the side piece 44.
  • the ejection spring is an elongated member with a central bent portion 52 and a free end or tab portion 53.
  • the location of the finger tab 53 is between spring retainer rib 24 and rear end wall 43, and immediately beneath the button B of the top wall 42.
  • operating end 53 moves considerably forward to the forward position shown in dotted lines in Fig. 4.
  • top plate assembly 20 Before placing top plate assembly 20 over the bottom plate assembly 30, the dust broom 60 is placed over the upper bottom wall 32 in a location best seen in Figs. 1, 3, and 5. Top plate assembly 20 is then placed over the bottom plate assembly 30 such that the side walls 22, 23 of the top plate assembly enclose both the ends of the dust broom and the side edges of the bottom walls 31, 32.
  • the tongues or ribs 29A on the lower inside surfaces of side walls 22, 23, then snap into small grooves 29B in the side edges of lower bottom wall 31, which is shown in Figs. 1, 5, and 6.
  • the top plate assembly 20 does not cover the rear extension 33 of upper bottom wall 32.
  • the next task is to attach spring support assembly
  • cover sheet 12 is slipped into upper grooves 26.
  • the pamphlet 14 is slipped from the back end of the case into the space between the two bottom walls, above the lower bottom wall 31, being necessarily bent in that process.
  • Half-circle cutouts 36, 37 are formed in the forward and rearward ends of lower bottom wall 31, in order to permit finger gripping of the pamphlet 14 when it is to be inserted or removed.
  • the CD may then be inserted into the case through the open front end, into the lower pair of grooves 27.
  • the two pairs of bumps 28A then serve to position the CD inside the case, each pair of protuberances being so spaced that when the flat circular member is stored in the box, respective chords of its circumference are retained by the pairs of protuberances 28 on the side walls.
  • a concave forward edge 70 of top wall 21 facilitates insertion of the CD.
  • Fig. 3 shows a set of bumps 28B which keep the CD from flying completely out of the package. The CD can then be grasped and pulled the rest of the way out of the package .
  • a disc carrier rides in grooves (not shown) in the side walls 122 and 123 of the case 120.
  • the carrier holds a CD (not shown) with fingers 82 in the center of the CD holding surface 84, as is common in the art. To release the CD, the fingers are slightly depressed, releasing their grip on the CD and allowing it to be removed.
  • the carrier 80 may have holding surfaces on both sides, permitting two CDs to be stored in a single case.
  • the ejection spring 150 of the second embodiment is preferably metal, and is securely affixed to the case near back end wall 135.
  • the ejection spring may have one or more loops 152 integrally formed in the spring.
  • the spring may also have a bend 154 at the point where it is retained by the rib of the release mechanism (not shown) .
  • the distal end 156 of the ejection spring may be securely affixed to the carrier 80 near the back edge 86 of the carrier, preventing the carrier 80 from extending out of the case 120 further than is necessary to remove the CD from the carrier.
  • Alternative means to restrain the spring and release it are also possible. For example a sliding latch or separate button could release the spring.
  • the release mechanism could contain the means to hold the spring and actuation of the mechanism could release it. It is also possible to have the release mechanism be part of the side wall . In this instance actuation would consist of depressing the mechanism and having an element traverse the case from side to side to release the spring. While the alternative embodiments of the invention have been disclosed in detail in order to comply with requirements of the patent laws, it will be understood by those skilled in the art that many variations are possible within the concept of the invention. For example, instead of using a flexible button B, it may be desired simply to leave an opening in the top wall 42.

Abstract
