Definitions

• the invention relates to a packaging unit of cardboard or the like, for information- carrying discs, of the kind stated in the preamble of claim 1 here below.
• Such a packaging unit is described in the publication WO/97/38919. It consists of an approximately square, flat casing and a kind of envelope inserted therein in a drawer-like manner, which envelope is obstructed from being extracted more than approximately half of its size.
• the envelope is preferably punched in one piece and folded, and also presents a separation plate and an underlying bottom plate.
• a disc can be put on top of the separation plate and is retained thereon by at least one flap in the separation plate, which is folded over the edge of the disc. By means of one or more flaps in the separation plate and a lid flap, the disc is kept in place in the packaging unit, almost fixed.
• a folder, so-called booklet can be inserted between the separation plate and the bottom plate.
• the information-carrying layer of the disc touches the foundation, making friction damages possible. It is in itself enough if elevated supporting elements at the periphery support the disc at areas that are unrecorded.
• the margin at the periphery will often be wide. However, according to valid standards, the margin does not have to be wider than 1.7 mm, concerning the normal compact disc and similar standard discs.
• the information layer clears the foundation
• the supporting elements as elevations with its highest points located on a circle, which is larger than the outer periphery of the disc, whereby the edge of the disc will come to rest against the parts of these elevations that face and slope towards the centre.
• Fig. 1 shows a material for an envelope.
• Fig. 2 shows a material for a casing for the envelope.
• Fig. 3 shows, partly sectioned, a folded and composed device with a compact disc inserted.
• Fig. 4 shows a second embodiment of a material for an envelope.
• Fig. 5 shows a third embodiment of a material for an envelope.
• Fig. 6 shows schematically and in a partial sectioned view how a compact disc is supported in an envelope according to the second or the third embodiment.
• Fig. 7 shows a readily folded envelope according to the second embodiment, with a disc inserted.
• the material of cardboard or the like, shown in Fig. 1, has a bottom plate 80, over which a lid flap 73 is folded via folds 71, 72 which determine the thickness of the envelope, a separation plate 74 which is folded over the bottom plate and which can have a circular contour, and flaps 76, 76' and 76".
• the folding line 75 of the separation plate forming a boundary between the bottom plate 80 and the separation plate 74, is located outside both folding lines 77, 78 belonging to the punched flap 76, and the distance of which approximately corresponds to the thickness of the comp- leted envelope, as well as the fold lines 71, 72 mentioned earlier.
• the flap 76 also forms a blocking flap, this being addressed closer here below.
• a folding line 79 serves to ease the control of a packed disc, after the partial extraction of the envelope from the casing.
• the material for a casing shown in Fig. 2, has a bottom part 84 and an upper part of the same size, both corresponding and adapted to insertion of the bottom plate 80 with parts of the envelope part belonging thereto. Assembled and glued together via side flaps, it has an inwardly folded flap 81 at its opening. This flap will spring downwards, and also the flap 76 (Fig. 1) will spring upwards, and at extraction they will hook onto each other and prevent a continued extraction. This appears clearer in the partly sectioned view in Fig. 3, which shows a partly extracted envelope with a separation plate, supporting a disc P.
• small stampings 86 have been made on the edge of the separation plate, according to Fig. 1, which stampings create elevations at the edges, against which the disc rests at the outer periphery. Additionally, the fold notches for the flaps have, which is apparent in Fig. 1, been doubled, which means that they no longer squeeze an inserted disc against the surface of the separation plate.
• the elevations are arranged as bosses, with its centres located outside the edge of the disc, so that the disc rests against the bosses at inwardly sloping parts.
• bosses 88 are pressed into the cardboard material, something, which can be performed in connection with the punching itself.
• the material in Fig. 4 resembles the material in Fig. 1.
• the material in Fig. 5 has additionally its bottom plate provided with bosses 89, which have to be pressed out from the opposite direction, generally causing a further manufacturing stage for the material.
• the booklet - meaning the usually enclosed folder - may possibly be provided with corresponding bosses (not shown in the figure).
• FIG. 6 shows schematically how a disc is located according to the preferred embodiment of the invention.
• a disc P is put on a separating plate 74', and what is shown is only a part of the disc P with its circular rim R, extending around the centre which is not shown, and an information area I, located outside the rim, and also the margin part M, which is empty of information, and according to valid standards may not be below 1.7 mm.
• the figure is essentially to scale.
• a boss 88 has its symmetry line 90 located just outside the edge of the disc, resulting in that the edge of the disc will be supported against the inwardly sloping part of the boss 88, which thereby supports the disc together with the rim R. From the figure it can also be seen that a certain small side movement may be permitted, within the manufacturing accuracy obtained regarding the location of the tongues 76', 76" and 73, in particular.
• Fig. 7 shows an envelope prior to insertion in a casing, with a disc P supported by bosses 8 and by the (not shown) circular rim at the middle.
• the bottom part has side recesses 100, which are located in front of the side edges of the disc, making possible a firm grip across the disc P, when the envelope is extracted to the stop position.
• supporting elements such as supporting bosses 86 and 87, 88, 89, respectively, is to use stamping tools, preferably with a plunger and a dye
• the supporting elements can be arranged in many different ways, for example by attaching drops of adhesive, arranged by small, cross-cutting flaps, etc., all being variations that are immediately available to the person skilled in the art.
