Abstract
Abstract A container for storing a tape cassette of the type having a pair of spaced tape reel hubs. Each hub has a cylindrical sidewall which defines a recess in the hub. The storage container includes enclosure means for receiving and enclosing a cassette in the container. Diametrically opposed pairs of fingers are molded integrally with a bottom wall of the container and project into the hub recess through an aligned access opening formed in a bottom wall of the tape cassette upon placing the cassette into the container. The fingers are formed with a convex outer camming surface and are connected to the container by a straight leg portion. The convex outer edges of the fingers are engaged by the hub sidewalls and flex inwardly upon initial placement of the cassette into the storage container. A rigid stop member is mounted adjacent to and inwardly of each of the flexible fingers to limit the inward movement of the fingers toward the flexed position to control the flex thereof and to prevent breakage of the fingers. The stop members are connected by intervening reinforcing ribs to form a rigid stop assembly.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
205 words
A container for storing a tape cassette, said cassette being of the type having at least one tape reel hub comprising a cylindrical sidewall defining a recess in the hub, said hub recess being accessible through an opening formed in a bottom wall of the cassette, said storage container including enclosure means for receiving and enclosing a tape cassette in the storage container; and hub engaging means formed on the storage container and located for entering the hub recess through the access opening when a cassette is placed in said container for preventing rotation of the tape reel hub; said hub engaging means including at least a first pair of flexible fingers formed on the storage container and movable between a normal outwardly biased position and an inwardly flexed position for engaging the sidewall of the hub when in the outward biased position to prevent rotation of the hub when the cassette is inserted into the storage container; and rigid first stop means located inwardly of and closely adjacent to each of said fingers and in general radial alignment with said fingers to limit the inward movement of said fingers toward the flexed position by engaging said fingers upon the inward movement of the fingers.
Claim 2
Dependent Claim
205 words
A container for storing a tape cassette, said cassette being of the type having at least one tape reel hub comprising a cylindrical sidewall defining a recess in the hub, said hub recess being accessible through an opening formed in a bottom wall of the cassette, said storage container including enclosure means for receiving and enclosing a tape cassette in the storage container; and hub engaging means formed on the storage container and located for entering the hub recess through the access opening when a cassette is placed in said container for preventing rotation of the tape reel hub; said hub engaging means including at least a first pair of flexible fingers formed on the storage container and movable between a normal outwardly biased position and an inwardly flexed position for engaging the sidewall of the hub when in the outward biased position to prevent rotation of the hub when the cassette is inserted into the storage container; and rigid first stop means located inwardly of and closely adjacent to each of said fingers and in general radial alignment with said fingers to limit the inward movement of said fingers toward the flexed position by engaging said fingers upon the inward movement of the fingers.
Claim 3
Dependent Claim
54 words
The container defined in claim 1 in which each of the fingers includes an outwardly convexly curved upper portion which serves as a camming surface for moving the finger toward the flexed position upon initial placement of a cassette into the storage container and into engagement with the sidewall of the tape reel hub.
Claim 4
Dependent Claim
38 words
The container defined in claim 2 in which each of the convex camming surfaces is connected to the storage container by a generally straight leg portion which is connected to and extends generally perpendicularly outwardly from the container,
Claim 5
Dependent Claim
33 words
The container defined in claim 1 in which the stop means is a generally flat member extending perpendicularly outwardly from the container a distance generally equal to the outward extension of said finger.
Claim 6
Dependent Claim
33 words
The container defined in claim 4 in which the fingers are spaced approximately 180° apart; and in which the flat members of the stop means are connected by a reinforcing rib extending therebetween.
Claim 7
Dependent Claim
26 words
The container defined in claim 5 in which a second pair of flexible fingers are located between said one pair of fingers and located 90° therefrom.
Claim 8
Dependent Claim
43 words
The container defined in claim 6 in which said first and second pairs of fingers form an imaginary circle having a diameter slightly greater than the diameter of the cylindrical sidewall of the hub when the fingers are in the normal biased positions.
Claim 9
Dependent Claim
31 words
The container defined in claim 6 in which second stop means are located adjacent to and inwardly of each of the second pair of flexible fingers to limit inward movement thereof.
Claim 10
Dependent Claim
30 words
The container defined in claim 8 in which a second reinforcing rib extends between the second stop means and extends perpendicularly to the reinforcing rib of the first stop means.
Claim 11
Dependent Claim
19 words
The container defined in claim 8 in which the second stop means are similar to the first stop means.
Claim 12
Dependent Claim
23 words
The container defined in claim 9 in which the first and second stop means and reinforcing ribs form a rigid integral one-piece member.
Claim 13
Dependent Claim
39 words
The container defined in claim 1 in which positioning means is formed on the storage container and projects into the access opening when a cassette is placed into the storage container for positioning the cassette in the storage container.
Claim 14
Dependent Claim
27 words
The device defined in claim 12 in which the positioning means is an annular member formed integrally with the storage container and encircles the pair of fingers.
Claim 15
Dependent Claim
