Instead of the resilient projections and circular holes described with reference to FIG. 5 two elongated holes 45 are provided through a CD sleeve 201 adjacent a bottom weld 206 . A thickening strip corresponding to the thickening strip 106 a is preferably present in this variant.
  • the CD sleeve may be received in a slot 25 in the holding part 24 described above.
  • the ribs 28 In lack of a resilient projection on the fastening strip the ribs 28 must in this case flex to allow the weld 206 to pass between the lateral projections 26 .
  • one longitudinal end 46 of the lateral projections is rounded or tapered while the opposite second longitudinal end 47 is blunt.
  • the blunt ends of the lateral projections 26 will catch the material of the CD sleeve 201 surrounding the elongated holes 45 impeding movement.
  • FIGS. 18 a to 18 e illustrates some different possible cross-sections of the slots and the lateral projections.
  • FIG. 18 a suggests that the lower sides of the lateral projections may be convergent in a direction opposite to the direction of insertion to provide for withdrawal of a sleeve in the direction opposite to the direction of insertion. A certain force must be applied to make the bottom weld slide over the lower sides and force the ribs apart to allow the bottom weld to pass.
  • the slots of the holding part may be closed in both longitudinal ends.
  • the slots are closed in both longitudinal ends it is avoided that sleeves may unintentionally slide out of an open end of a slot.
  • FIG. 18 b suggest that a single lateral projection is provided. This would e.g. provide for only one orientation of the CD sleeve 101 because the resilient projections must meet the lateral projection in order to ensure a fastening engagement.
  • a spring element 50 may be present in a slot with lateral projections in only one side to force e.g. the elongated hole 45 of CD sleeve 201 into engagement with the lateral projection.
  • a corresponding effect may be obtained as suggested in FIG. 18 d where the spring element 50 is so to speak substituted by a guide element 51 guiding the bottom weld of a sleeve during insertion.
  • the spring element 50 is so to speak substituted by a guide element 51 guiding the bottom weld of a sleeve during insertion.
  • inherent flexibility of the material of the sleeve will substitute the action of the spring element 50 .
  • FIG. 18 e illustrates that the lateral projections in a slot need not be identical.
  • an asymmetry is obtained providing for different characters of the engagement between lateral projections and the fastening strip of a sleeve.
  • the CD sleeve 101 may be withdrawn from the slot in the direction opposite to the direction of insertion 33 if the resilient projection 112 engages a lateral projection 26 a the lower side of which has a steep slant, whereas such withdrawal may be impeded if the resilient projection 112 engages another lateral projection 26 b with a lower side with a flat or missing slant.
  • FIGS. 19 a to 19 e illustrates different longitudinal extends of the lateral projections 26 .
  • FIG. 19 a suggests two sets of opposing lateral projections with blunt ends.
  • FIG. 19 b suggests three sets of opposing lateral projections. This embodiment may e.g. be use full in case of larger sleeves than the sleeves describes above.
  • FIG. 19 c indicates an embodiment in which the lateral projections extend in substantially the full length of the slot. This embodiment is not use full with sleeves where the fastening strip comprises elongated holes instead of resilient projections.
  • FIG. 19 d shows the embodiment also shown in FIGS. 7 and 13 where the lateral projections comprise one blunt and one tapered or rounded longitudinal end.
  • FIG. 19 e suggests that lateral projections are tapered or rounded in both longitudinal ends.
  • the CD sleeve 101 comprise front sheet 102 and back sheet 105 of thickness approximately 0.12 mm and thickening strip of thickness approximately 0.4 mm including also the first central sheet 104 the weld 106 has a thickness of approximately 0.85 mm the resilient projections 112 extending some 0.1 mm above that.
  • a holding part 24 with a clearance of approximately 0.8 mm betweens the lateral projections has provided satisfactory results.
  • the thickness of the sleeves and the clearance between the lateral projections may vary within the scope of the claims.
  • the reinforcement strip is in preferred embodiment of a more rigid sheet material than the front, back and central sheets and has e.g. a thickness of approximately 0.3 mm.
  • the size of the clearance between the lateral projections, or between the lateral projection and the opposing rib side in case of slots with unilateral projections, cf. FIG. 18 b should be adapted to the sleeves intended for mounting in the holder.
  • the clearance should allow the ribs defining a slot to flex through the clearances of the adjacent slots.
  • the clearance should be at least one third of the thickness of the fastening strip of the sleeves in question (or vice versa).
  • the clearance should of course be less than the thickness of said fastening strip, unless other means are provided for ensuring engagement between the lateral projections and fastening strip, cf. FIGS. 18 c and 18 d.
  • the fastening strip may comprise only two sheet of approximately 0.1 mm thickness i.e. the fastening strip may be only approximately 0.2 mm thick. In this case the clearance may by e.g. approximately 0.1 mm.
  • the CD sleeve may be modified to contain two CDs within the scope of the following claims.
  • the sleeve may e.g. be modified by inserting an additional sheet between the back sheet 105 and the first central sheet 104 thus providing a pocket for a graphics back cover between the back sheet 105 and the additional sheet and providing a pocket for a second CD between the first central sheet 104 and the additional sheet.
  • the depth of the pocket for the second CD should be restricted like the central pocket 108 e.g. by incorporating the additional sheet in the arc-shaped weld 111 .
  • the single central flap 4 d could be substituted by two flaps placed side-by-side thus providing a flap for each CD. Another possibility would be to provide a small flap inside a bigger flap.
