Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention pertains to a package, and more particularly, pertains to a rigid memory disk package for rigid memory disks used in the computer field. The package can also be used for optical disks. 
     2. Description of the Prior Art 
     The prior art packages have generally been designated for silicone wafers for integrated circuits. The prior art packages were not particularly adaptable to rigid hard memory disks or rigid hard optical disks. Both of these forms of storage media have recently achieved popularity in the computer fields and consequently, have required their own high technology packaging requirements accordingly. 
     Also, the prior art packages do not easily lend themselves to robotic processing and did not have a low base profile of the base supporting the disks in either a horizontal or vertical position for robotic processing. 
     The present invention provides a rigid disk package for storing either memory disks or optical disks and is of a low profile design, particularly intended for robotic handling and processing in either a horizontal or vertical position. Also, the rigid disk package has clean contours for preventing contamination and provides for accommodation of a sealing band providing for an air tight, dust free, moisture free atmosphere in the package. 
     SUMMARY OF THE INVENTION 
     The general purpose of the present invention is a rigid disk package for storing of either memory disks or optical disks. The package is of a smooth surface design and smooth contour, so as to prevent contamination by picking up of dirt. The package includes an area for accommodating a seal member for providing for a secure inner environment, and is of a low profile design which lends itself to robotic processing in either a horizontal or vertical position. 
     According to one embodiment of the present invention, there is provided a package base, a package cover, and two locking clips which secure within areas of the package base and snap into the package cover. 
     According to another embodiment of the present invention, there is provided a rigid disk package including a package base, a package cover and locking clips which engage into areas at either end of the package base and include a upwardly extending spring member which snaps into areas of the package cover. The package base includes a curved bottom with divider teeth for supporting a plurality of disks therebetween. Each of the locking clips is engaged within a lower area of the base at each end and includes an area in which to provide for spring biased movement for subsequent engagement into the ends of the package cover. The package cover includes a plurality of like teeth, spaced on opposing sides and two lines of opposing spaced fingers in the top of the package for engaging against the disks and holding the disks against movement within the package base and within the package cover. A configured groove is provided in the base for accommodating a flexible seal ring preventing moisture and contamination from passing through between the engagement of the package base to the package top.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIG. 1 illustrates in partial cross section a rigid memory disk package 10 including major components of a package base 12, a package cover 14, and removable locking clips 16 and 18. For purposes of reference, FIG. 8 illustrates the components 12, 14, 16 and 18 assembled, in a partial cross sectional view. Reference is now made to FIGS. 1-8 in the following discussion with reference particularly now to FIG. 1 as set forth below. 
     FIG. 1 illustrates the package base 12 which includes rounded curved bottoms 20 and 22 extending longitudinally between vertical end members 24 and 26 with a flat section 28 therebetween. Configured groove 30 and a like aligned configured inner lip 32 and edge 33 extend about and around the upper portion of the curved bottoms 20 and 22, adjacent to the end members. The lip 32 serves to seal the base 12 with a corresponding groove 34 and lip 35 and in the top cover 14. Integral half round support rods 36 and 38, and support struts 40-46 position along, about, and beneath the configured groove 30 providing additional groove support and integral package strength. 
     A alternating plurality of partial cylindrical shaped divider teeth 48a-48n and disk grooves or slots 50a-50n extend upwardly and inwardly from the inner surface of curved bottom members 20 and 22 and flat member 28 for retaining rigid disks as later illustrated and discussed in detail. Configured securing locking clip containment housings 52 and 54 position at the opposing ends of the base 12, and extend downwardly from, and about the configured groove 30. The locking clips 16 and 18 accommodate and engage within housings 52 and 54 with housing 54 now being described in detail. The housing 52 is a mirror image thereof. 
     The housing 54 includes a rectangular like hole or pocket 56 for insertion of the locking clip within housing 54. The housing member 54 includes a configured side member 60 between two vertical members 62 and 64 including vertical lips 66 and 68 and includes a catch 71 formed by the lower edge of member 60.
