Abstract
Abstract A case for video or audio cassettes composed of an upper housing part and a lower housing part that are foldably joined together by means of a hinge to completely enclose the cassette. At least one elastic element is installed between the upper part and the lower part in such a way that when a closure is disengaged the upper and lower parts are forced apart and the package swings open automatically. In particular, the cassette itself is located in a separate holder that is held between the upper part and the lower part in their common pivot axis, with the elastic elements then operating between this holder and the upper and lower parts. The effect of this is that when the closure, particularly a snap closure, is disengaged, not only do the upper and lower parts swing open automatically, but the holder with the cassette is brought into an angular position that roughly bisects the angle between the upper and lower parts when open. The cassette is thus easy to remove and to replace in the holder.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
172 words
A case for storing and completely enclosing a recording medium when the medium is not in use, said case comprising: a housing composed of an upper housing part and a lower housing part; a holder for retaining the recording medium, said holder being disposed between said upper and lower parts; hinge means connected for permitting relative movement between said upper and lower parts about a hinge axis between a closed position in which said parts are closely adjacent one another and an open position in which said parts are pivoted away from one another; closure means for retaining said parts in said closed position, said closure means being manually operable for permitting said parts to move to said open position; and spring means interposed between, and connected to one of, said holder and one of said parts for moving said parts to said open position and placing said holder in a position in which a recording medium retained by said holder is presented for removal when said closure means is manually operated.
Claim 2
Dependent Claim
172 words
A case for storing and completely enclosing a recording medium when the medium is not in use, said case comprising: a housing composed of an upper housing part and a lower housing part; a holder for retaining the recording medium, said holder being disposed between said upper and lower parts; hinge means connected for permitting relative movement between said upper and lower parts about a hinge axis between a closed position in which said parts are closely adjacent one another and an open position in which said parts are pivoted away from one another; closure means for retaining said parts in said closed position, said closure means being manually operable for permitting said parts to move to said open position; and spring means interposed between, and connected to one of, said holder and one of said parts for moving said parts to said open position and placing said holder in a position in which a recording medium retained by said holder is presented for removal when said closure means is manually operated.
Claim 3
Dependent Claim
56 words
A case as defined in claim 1 wherein said spring means comprise at least one spring element having a first end connected to one of said holder and one of said parts and a second end which bears resiliently against and is movable relative to the other one of said holder and one of said parts.
Claim 4
Dependent Claim
22 words
A case as defined in claim 1 wherein said holder is mounted in said case for pivotal movement about said hinge axis.
Claim 5
Dependent Claim
26 words
A case as defined in claim 1 wherein said spring means comprise at least one S-shaped strip interposed between one of said parts and said holder.
Claim 6
Dependent Claim
61 words
A case as defined in claim 1 wherein said closure means comprise at least one snap closure disposed between said upper and lower parts and composed of an elastic member secured to one of said parts and a recess formed in the other one of said parts for engagement by said elastic member when said parts are in said closed position.
Claim 7
Dependent Claim
27 words
A case as defined in claim 1 wherein said housing parts and said holder are formed such that said holder defines an outer wall of said case.
