Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 141 words
A case for accommodating a rotary recording medium comprising: a jacket having an opening at one end, for receiving and accommodating a rotary recording medium within an internal space provided within said jacket; and a detachable lid member for closing the opening of the jacket accommodating said rotary recording medium, said jacket having a two-piece construction consisting solely of a flat and hollow jacket main body having openings at first and rear ends thereof and unitarily having upper and lower sheet parts and right and left side walls, and a rear lid fixed to and closing the rear end opening of said jacket main body, said rear lid having a receiving part for receiving said rotary recording medium, said jacket main body being obtained by cutting a flat and hollow tube-shaped member formed by a modified extrusion into a predetermined length.
Claim 2
Dependent Claim 141 words
A case for accommodating a rotary recording medium comprising: a jacket having an opening at one end, for receiving and accommodating a rotary recording medium within an internal space provided within said jacket; and a detachable lid member for closing the opening of the jacket accommodating said rotary recording medium, said jacket having a two-piece construction consisting solely of a flat and hollow jacket main body having openings at first and rear ends thereof and unitarily having upper and lower sheet parts and right and left side walls, and a rear lid fixed to and closing the rear end opening of said jacket main body, said rear lid having a receiving part for receiving said rotary recording medium, said jacket main body being obtained by cutting a flat and hollow tube-shaped member formed by a modified extrusion into a predetermined length.
Claim 3
Dependent Claim 52 words
A case as claimed in claim 1 in which said jacket main body consists of upper and lower sheet parts having right and left side thick portions, and thin portions occupying parts between the right and left thick portions having surfaces lower than the surfaces of said thick portions by one step.
Claim 4
Dependent Claim 26 words
A case as claimed in claim 1 in which said jacket main body has upper and lower sheet parts provided with vertical stripes on surfaces thereof.
Claim 5
Dependent Claim 41 words
A case as claimed in claim 3 in which said jacket main body is provided with a plurality of grooves extending along the longitudinal direction of said jacket main body on the surfaces of the right and left side thick portions.
Claim 6
Dependent Claim 45 words
A case as claimed in claim 1 in which said jacket main body has resilient deformation parts in a vicinity of right and left sides thereof on the upper and lower sheet parts, for enabling a facilitated resilient deformation of said opening upon enlargement thereof.
Claim 7
Dependent Claim 36 words
A case as claimed in claim 5 in which said resilient deformation parts are a plurality of grooves arranged and provided adjacent to each other and extending along the longitudinal direction of said jacket main body.
Claim 8
Dependent Claim 83 words
A case as claimed in claim 2 in which said jacket main body has resilient deformation allowing parts on right and left sides of the thin portions of the upper and lower sheet parts, for enabling a facilitated deformation of said opening upon enlargement thereof, said resilient deformation allowing parts comprise a plurality of grooves forming thin parts arranged and provided adjacent to each other and extending along the longitudinal direction of said jacket main body, and projections formed between said adjacent grooves.
Claim 9
Dependent Claim 62 words
A case as claimed in claim 1 in which said jacket main body has a transparent part or semitransparent part which is transparent or semitransparent at least in part, said transparent or semitransparent part opposes an indication part of said rotary recording medium, and said transparent or semitransparent part is made from a transparent or semitransparent material mixed with reflecting metal particles.
Claim 10
Dependent Claim 60 words
A case as claimed in claim 1 in which said rear lid has an inserting part inserted within said jacket main body, and said inserting part is of a narrow band shape wherein a projecting length at a part in the vicinity of the right and left sides is substantially equal to a projecting length at a center part thereof.
Claim 11
Dependent Claim 58 words
A case as claimed in claim 1 in which said rear lid has an inserting part inserted within said jacket main body, and said inserting part is of an arcuate shape wherein a projecting length at a part in the vicinity of the right and left sides is larger than a projecting length at a center part thereof.
Claim 12
Dependent Claim 18 words
A case as claimed in claim 9 in which said inserting part is of a latticed frame construction.
Claim 13
Dependent Claim 29 words
A case as claimed in claim 1 in which said rear lid is made from a synthetic foam material moulded by assembling said jacket main body into mould dies.
Claim 14
Dependent Claim 53 words
A case as claimed in claim 1 in which said jacket is provided with sloping parts of tapered shapes at the edges of said upper and lower sheet parts of said jacket main body at said opening, and said sloping parts operate together to form the tapered shapes spreading out towards said opening.
Claim 15
Dependent Claim 55 words
A case as claimed in claim 1 in which said jacket is provided with inwardly projecting parts opposing each other upwards and downwards on said upper and lower sheet parts, and said inwardly projecting parts are formed by bending side edge parts of windows in the vicinity of said opening inwards in a projecting manner.
Claim 16
Dependent Claim 36 words
A case as claimed in claim 1 in which said jacket is provided with embossed cylindrical projections opposing each other upwards and downwards on said upper and lower sheet parts, in the vicinity of said opening.
Claim 17
Dependent Claim 35 words
A case as claimed in claim 1 in which said rear lid has a shape wherein corner parts of the right and left sides at the rear end thereof are formed as arcuate corner parts.
Claim 18
Dependent Claim 58 words
