Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 302 words
A protective jacket for accommodating therein a flexible foil-type disc record comprising: first and second plate members; a substantially U-shaped spacer secured to said first and second plate members thereby joining said first and second plate members to each other while forming a chamber therebetween for receiving therein said disc record through an opening defined between said first and second plate members and said spacer; a lid provided in the first plate member for selectively closing and opening said chamber to enable the disc record to be confined within said chamber and to be taken out of said chamber, respectively; hinge means for hingedly supporting said lid to said first plate member, said hinge means being positioned on said first plate member to permit a portion of the disc record to be exposed to the outside of the protective jacket when said lid is in position to open said chamber; at least one pair of access openings formed in a spaced relation to each other in one edge portion of said second plate member adjacent said opening defined by said first and second plate members and said spacer, each of said access openings terminating at a position which is adjacent the outer periphery of the disc record accommodated within said chamber and which does not overlap said outer periphery of said disc record; and separate means for connecting said lid to said second plate member thereby substantially sealing the opening of said chamber, a portion of said second plate member which is opposed to said separate means being flush with the inside surface of said second plate member while a corresponding portion of said first plate member which faces said portion of said second plate member is projected towards said second plate member a distance corresponding to the thickness of said spacer.
