Definitions

  • the present invention relates to cases for data carrying discs.
  • Data carrying discs such as audio compact discs, CD- ROMs, video discs and so forth incorporate a recording medium in which data may be recorded and subsequently retrieved, typically by an optical or a magnetic device acting through a data surface of the disc.
  • the disc has a central through hole, the principal purpose of which is to facilitate rotation of the disc about its centre during retrieval and/or recording of data.
  • a storage case In order to protect such a disc from damage, it is common practice to provide it with a storage case. At is simplest, this may be little more than an envelope in which a disc may be stored. However, in applications where it is to be expected that a disc will be frequently inserted into and removed from its case, it may be preferable that the data surface does not come into contact with the case, to avoid the risk of its being damaged by abrasion. This is a particularly important consideration in respect of audio compact discs, which are liable to experience casual handling and poor cleanliness .
  • a further important feature of a case for a data carrying disc is its ability to display information about the disc. This information may comprise a printed sheet, a booklet, or both.
  • This trend for producing CD-Rom discs for computers (which are physically similar to audio compact discs) has given rise to a need for increased documentation to accompany a disc. Therefore the amount of space available for receiving documentation is of particular importance in a case for such discs.
  • the most commonly used type of case for audio compact discs is constructed from three separate parts: a disc storage tray, a base, and a lid.
  • the base and the lid are made of a hard transparent plastics material
  • the disc storage tray is made of an opaque hard plastics material.
  • the disc storage tray is rectangular in plan and has a recess in which a disc may be stored. Centrally of the recess, there is a raised portion from which projects a plurality of lugs. These are arranged to grip the disc about is central hole in order to retain the disc in place in the recess.
  • the disc storage tray is secured within the base.
  • the lid is pivotally connected to the base such that it can * be moved between a closed condition in which it encloses a disc held in the tray, and an open condition in which the tray is freely accessible.
  • This type of case has many disadvantages: it can only store a quite thin booklet of information (this being typically secured to the lid) ; it is prone to damage on account of its being constructed from a brittle material; and it is expensive to manufacture due to its complexity.
  • An aim of the present invention is to ameliorate or overcome the problems associated with the above described cases for data carrying discs.
  • the present invention provides a case for storing a data carrying disc formed by folding a blank of sheet material, and having a disc holding formation for holding a disc by engagement with portions of the disc adjacent its central hole.
  • Such a case may be manufactured considerably more easily and with less cost than the known type of case described above, yet, unlike an envelope, contact between the data surface and the case can be avoided.
  • the disc holding formation may be integral with the single sheet of material, this having the advantage of simplicity and convenience of manufacture.
  • the disc holding formation may comprise a discrete component which cooperates with the single sheet.
  • the material from which the sheet is made is receptive to print.
  • a case may therefore carry printed information relating to a disc contained within it.
  • a suitable material from which the case can be manufactured is polypropylene. This material has suitable properties in manufacture and use, can be printed on and is recyclable.
  • the case may advantageously have an enclosure suitable for receiving documentation.
  • the disc holding formation holds a disc such that its data surface is separated from all parts of the case.
  • the invention provides a case for a data carrying disc characterised by being formed by folding a unitary blank of sheet material, which blank has a plurality of panels interconnected by fold lines, the blank having an inner disc supporting panel and an outer disc supporting panel there being formed in the inner supporting panel a tongue of material, the periphery of which is defined by a cut line through the blank, and there being formed in the outer disc supporting panel first and second slots; in which the outer disc supporting panel overlies the inner disc supporting panel when the blank is folded and the tongue extends through the first slit and an end portion of the tongue is received in the second slit such that the tongue is maintained in a curved condition, a central region of it being spaced from the outer disc supporting panel, the central region being shaped to retain a data carrying disc by engagement with material of the disc adjacent a central hole thereof.
  • a third aspect of the present invention provides a blank for a case according to the first aspect of the invention.
  • Figure 1 is a plan view of a blank from which a case for a data carrying disc embodying the invention may be formed;
  • Figure 2 shows a case formed from the blank of Figure 1.
  • a blank 1 from which a case for a data carrying disc embodying the invention may be formed comprises a flat sheet of polypropylene, having a peripheral shape in a general form of a cross.
  • the blank comprises a centre panel 2, around which, in a cross shape, are disposed, on a major axis A, a first side panel 3, a second side panel 4, and, on a minor axis B, an inner disc supporting panel 5 and an outer disc supporting panel 6.
  • Each of the side panels 3,4 and the disc supporting panels 5,6 are spaced from the central panel 2 by a respective intermediate panel 31,41,51,61.
  • each boundary between adjacent panels is defined by a respective fold line 10.
  • Each fold line 10 is constituted by a straight line of weakness, along which the material of the blank may be readily folded.
  • the line of weakness is formed by scoring (or in another suitable manner) to create a line of reduced thickness in the material of the blank 1.
  • Each side panel 3,4 is connected by a respective intermediate panel 31, 41, to opposite shorter sides of the central panel 2.
  • the central panel 2 and the first side panel 3 are rectangular and have similar dimensions, and each has a major and a minor axis along each of which it is of dimension is greater than the diameter of a disc to be stored in the case.
  • the second side panel 4 is of substantially similar shape and dimension to the first side panel, but additionally carries two lugs 42, spaces symmetrically about the major axis A, each of which projects from an edge opposite the central panel 2.
  • Each of the lugs 42 is generally semicircular, and is connected to the second side panel 4 along a straight line of weakness 44, substantially as described above.
  • a pair of through slits 32 is formed to lie on the line of weakness (indicated at 10') between the first side panel 3 and the adjacent connecting panel 31, these being disposed symmetrically about the major axis A to receive the lugs 42 when the blank 1 is folded to form a case, as will be described.
  • the inner and outer disc supporting panels 5, 6 are connected to opposite long edges of the central panel 2 by respective connecting panels 51, 61.
  • the inner disc supporting panel 5 is generally rectangular in outline. Its corners remote from the connecting panel 51 are rounded.
  • a disc carrying formation 52 is formed within the inner disc supporting panel 5.
  • the formation is defined by a through cut 53 which defines a shaped region of the panel 5 which is symmetrical about the minor axis B.
  • the through cut 53 defines a curve which is not closed, such that the shaped region is not completely detached from the rest of the panel 5.
  • the shaped region may be considered to comprise four portions disposed symmetrically about the minor axis B.
  • a first portion 54 is semi-circular, being defined by a straight line extending parallel to the major axis. End portions 53' of the cut 53 extend along short end portions of the straight line.
  • An intermediate portion 55 is generally circular and extends from the first portion 54 along the minor axis B towards the centre panel 2.
  • the first portion 54 and the intermediate portion 55 are interconnected at a line of weakness 56 extending parallel to the major axis A and defining a chord of both the first portion 54 and the intermediate portion 55.
  • a third portion 57 is semi-circular and connected to the intermediate portion 55 at a line of weakness 58 so as to be generally symmetrical with the first portion 54 about the intermediate portion 55.
  • a semi-circular projection is disposed on the minor axis B projecting from the third portion 56 towards the central panel 2, the projection 59 having a radius approximately one third that of the third portion 56.
  • the centre of the projection 59 is approximately at the centre of the inner disc supporting panel 5.
  • a pair of curved slits 52a are formed through the inner disc supporting panel 5, these being disposed symmetrically about the minor axis B. The purpose and disposition of these slits 52a will become apparent from the description, below, of the erected case.
  • the outer disc supporting panel 6 has a general rectangular outline. Corner regions 62 of the outer disc supporting panel 6 remote from the connecting panel 61 are cut away to define, at each region 62, a projecting lug 63 of generally semi-circular outline.
  • a first slit 64 is formed through the outer disc supporting panel 6, to extend symmetrically of the minor axis B and to pass approximately through the centre of the panel 6.
  • the slit is generally straight and parallel with the major axis A and it with short end portions which are angled away from the centre panel 2.
  • a second slit 65 is formed thorough the outer disc supporting panel 6, to extend symmetrically of the minor axis B.
  • the slit is generally straight and parallel with the major axis A and it with short end portions which are angled towards the centre panel 2.
  • the first slit 64 is between the centre panel 2 and the second slit 65.
  • the first side panel 3 is folded over the centre panel 2, to lie parallel with it;
  • Each lug 63 of the outer disc securing panel 6 is inserted into a respective curved slit 52a of the inner disc securing panel 5;
  • the second side panel 4 is still free. This can be folded to a closed condition to cover the disc securing panels 5,6 and can be releasably retained by inserting each of its projections 42 into a respective slits 32.
  • the disc carrying formation 52 is dimensioned such that, once its semi-circular projection 59 is inserted into the second slit 65, its first and third portions 54, 57 project angularly from the outer disc securing panel 6, the intermediate portion 55 being spaced from and generally parallel to the disc securing panel.
  • the relative positions of the curved slits 52a and the lugs 63 are such that the lugs 63 are retained within the slits 52a in the erected case to resist removal in a direction generally parallel to the minor axis B.
  • a disc may be supported by passing the intermediate portion 55 of the disc supporting formation through its central hole, the intermediate portion 55 being dimensioned to be a tight fit so as to resist removal of the disc.
  • the first and third portions 54,57 ensure that the disc remains spaced from the disc supporting panels 5,6.
  • the disc may be further protected by folding the second side panel 4 as described in the last-but-one preceding paragraph.
  • the first side panel 3 In its erected state, the first side panel 3 is spaced from the central panel 2 by the connecting panels 31,41,51,61. This defines a cuboidal space which may be used for storage, for example, of documents which relate to a disc. This space is closed by the connecting panel 41 between the centre panel 2 and the first side panel only when the first side panel 4 is in its closed condition. Any or all of the panels may be printed, for example with descriptive material relating to a disc.
  • the connecting panels may be omitted.

Abstract

Cette invention concerne un boîtier destiné à un disque porteur de données tel qu'un disque compact musical ou des CD-Rom. Ce boîtier est formé en pliant une ébauche unique (1) faite d'une feuille de matériau. Cette ébauche se compose de plusieurs panneaux connectés les uns aux autres par des lignes de pliage. Ces panneaux comprennent un panneau central (2), des panneaux interne et externe (5, 6) portant des disques, ainsi qu'un premier et un second panneau latéral (3, 4) qui sont chacun connectés au panneau central (2) par des panneaux intermédiaires (51, 61, 31, 41). Le panneau de support interne (5) possède une languette (52) faite d'un matériau donné et dont la périphérie est définie par une ligne de découpage (53) pratiquée dans l'ébauche (1), tandis que le panneau externe (6) de support de disque comporte des première et seconde fentes (64, 65). Lorsqu'il est replié, le panneau externe (6) de support de disque recouvre le panneau interne (5) de support de disque tandis que la languette (52) pénètre dans la première fente (64). La partie d'extrémité de la languette (52) pénètre dans la seconde fente (65) de manière à ce que ladite languette (52) soit maintenue en une position courbe et forme ainsi une structure de maintien du disque. La zone centrale de cette structure est espacée du panneau externe (6) de support de disque, et possède une forme lui permettant de retenir un disque porteur de données lorsqu'elle entre en contact avec le matériau dont est fait le disque, à proximité d'un trou central pratiqué dans ce dernier.
