AN IMPROVED JEWEL CASE ASSEMBLY FOR HOLDING CDS AND A METHOD FOR HOLDING CDS APPLYING THE IMPROVED JEWEL CASE ASSEMBLY
FIELD OF THE INVENTION
The present invention relates in general to an improved jewel case assembly for holding CDs, in a technically safe and secured manner and also ensuring cost effectiveness, and easy handling and in particular, to an improved jewel case assembly ,having a specially designed central jaw, incorporated on the base portion of the jewel case, and fused therewith to a single component, whereby the desired objectives of the present invention, like holding two or more CDs together, in a single two-piece jewel case assembly without the need for any tray, is achieved. BACKGROUND OF THE INVENTION
The present invention is applicable in the areas of Optical Media and Entertainment. Traditionally, it is known in the art that the jewel case asemblies available for holding CDS, comprises three parts viz. a bottom, a lid and a tray. Ideally, it is the tray , which sustains the disc in the center hub. Now, these jewel case assemblies are very costly and furthermore, such assemblies can hold only one CD and are not so suitable for easy handling. These jewel case assemblies, are also not so suitable in respect of holding the CDs, in a technically safe and secured manner, particularly having regard to the fact that such assemblies, are not adapted to sustain two or more discs on them, cohesively such that, if the jewel case is inverted, the discs do not fall with their own weight. Additionally, such assemblies are very prone to allowing, entry of dust particles. Also, such assemblies, known in the art, involved utilizing many plastic parts and papers, resulting in cropping up of environmental hazards.
Hence there was long felt need to design an improved jewel case assembly, for holding two or more CDs, in a technically safe and secured manner, so that two or more CDs are hold together in a single two-piece jewel case assembly, without the need for any tray and also to ensure that the assembly is adapted to sustain two or more discs,

cohesively, such that, if the jewel case assembly is inverted, the discs do not fall with
their own weight . There was also a long felt need, to reduce the utilization of plastic
parts and papers involved in manufacturing jewel case assembly. Furthermore, for
considerable period of time, research is on for reducing the entry of dust in jewel case
assemblies for holding CDs.
The jewel case assembly for holding CDs, in accordance with the present invention,
aims at achieving the the aforesaid needs.
All through out the specification including the claims, for the sake of understanding,
reference has been made solely to CDs but is not limited to it. It is further clarified that
the present invention, is also applicable to DVDs and the like.
OBJECTS OF THE INVENTION
It is a prime object of the present invention to provide an improved jewel assembly for
holding two or more CDs in a technically safe and secured manner and simultaneously,
ensuring cost effectiveness, low usage of paper and plastic materials and easy
handling.
It is a further object of the present invention to provide an improved jewel assembly for
holding two or more CDs in a single two-piece jewel case assembly, without the need
for any tray.
It is a further object of the present invention to provide an improved jewel assembly ,
adapted to sustain two or more discs , cohesively, such that, if the jewel case assembly
is inverted, the discs do not fall with their own weight.
It is a further object of the present invention to provide an improved jewel assembly,
adapted to reduce the entry of dust inside it, during its operation.
It is a further object of the present invention to provide an improved jewel assembly,
which is environment friendly.
It is another object of the present invention to provide an improved jewel assembly,
which can accommodate change in the mold.
It is a further object of the present invention to provide an improved jewel assembly
having specially designed ribs, to prevent scratches on the discs.

BRIEF DESCRIPTION OF THE INVENTION
The following, describes some non-limiting preferred embodiments of the present
invention, with reference to the accompanying drawings as detailed aforesaid.
As can be seen from Fig 1, according to a preferred embodiment of the present
invention, the improved jewel case assembly comprises a central jaw (3), incorporated
on the base (1), and fused therewith so as to form a single unit. The base(1), may be
specially designed to prevent any dust. There may be provided specially designed ribs
along the top circumference of the base, for the purpose of avoiding scratches on the
discs.
Fig 1 (a) illustrates the critical area(4) of the central jaw (3), illustrated in Fig 1 . This is

the part which holds the discs. This center jaw is further divided into a plurality of flexible flanges, which sustain two or discs tightly, such that that if the Jewel Case is inverted the discs do not fall with their own weight. The number of flanges may be five in number and is not limited to this number. Fig 2 illustrates the jewel case, in accordance with the invention, where two discs(5) are hold together. Fig 3 illustrates specially designed base(6) of the jewel case of the present invention, for the purpose of preventing dust.
Generally, the Jewel Case assemblies known in the art consists of three pats viz. a bottom, a lid and a tray. It is only the tray, which sustains the disc in the center hub. The present invention embraces the idea, that if the center hub/jaw (holding arrangement) is incorporated on the bottom part itself,.a full part and the related processes is eliminated. Moreover, the space so generated, is utilized for placing two or more extra discs .No specific prior art of this nature existed. According to the present invention, the two-part design with three discs, have been proposed for the first time, instead of three-part design with one disc. The undercuts in the mold were specially designed with an optimum draft angle for the ease of ejection and to qualify all the quality parameters in terms of endurance and runability.
As stated before, the primary objective of the present invention is to develop a low cost two part jewel case that will sustain two or more discs within it . To achieve the above objective, the tray and the bottom part of the jewel case were fused together, to get an all new component - the bottom with the center jaw. Moreover, the height of the center hub was increased to accommodate two or more discs in the same case. For this purpose, the whole design of the center jaw was reviewed and all the draft angles and undercuts were redesigned with an eye on the mold manufacturing ease, so that there may not arise any problem while ejection.
Following are some of the advantages achieved:
a) Design of the new Bottom part (Fig.1) with a specially designed center jaw

which is capable to accommodate 2 CDs (Fig.2) without any change in the outer dimensions.
b) Development of the mold for the above design.
c)Design reviews to remove the obstacles to make the mold fit for production. d)Design modified (Fig 3) to avoid the dust to enter in the Jewel Case, resulting in damage of the case. e)Change in the mold unlike the conventional designs, f) )Quality checking of the samples with proper validation and verification.
The present invention has been described with reference to some drawings and preferred embodiments, purely for the sake of understanding and not by way of any limitation and the present invention includes all legitimate developments within the scope of what has been described hereinbefore and what has been claimed hereinafter.
