Abstract
Abstract A container for storing a magnetic tape cassette is formed by a one-piece housing, preferably molded of plastic resin and including a substantially rectangular bottom wall having side walls and a back wall directed upwardly along its opposite side and back margins to define a cavity which is open at the top for receiving a cassette and has an opening at the front of the housing through which access may be had to a cassette in the cavity for upwardly dislodging the cassette therefrom, and a top wall or lid hingedly connected, as by a thin cross-section of the plastic, to the top of the back wall for swinging between an upwardly directed opened position and a closed position in which the lid closes the cavity at the top thereof while a flange depending from the front end of the lid closes the opening at the front of the housing. The lid and bottom wall of the housing have mating projections which are frictionally engageable for holding the lid in its closed position and also for preventing rotation of the reels of a cassette stored in the container. Further, the opposite side walls are formed with a groove and rail, respectively, of mating dovetail cross-sections by which a plurality of containers can be secured to each other in side-by-side relation, and the rail preferably terminates short of the front and back ends of the respective side wall and has a medial recess extending along its length for facilitating its engagement in the groove of an adjacent identical container.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
195 words
A container for storing a magnetic tape cassette comprising a one-piece housing including a substantially rectangular bottom wall, and side walls and a back wall directed upwardly along the opposite side and back margins, respectively, of said bottom wall to define a cavity which is open at the top for receiving a cassette and has an opening at the front of the housing extending substantially down to said bottom wall and through which access may be had to a cassette in the cavity for upwardly dislodging the cassette therefrom, and a top wall hingedly connected, at one end, to the top of said back wall for swinging between an upwardly directed opened position and a closed position in which said top wall extends between said side walls to close said cavity at the top of the latter, said top wall having a depending flange at the end thereof remote from its hinged connection to said back wall for closing said opening at the front of the housing in said closed position of the top wall; and means engageable in said closed position of the top wall for releasably holding the latter in said closed position.
Claim 2
Dependent Claim
195 words
A container for storing a magnetic tape cassette comprising a one-piece housing including a substantially rectangular bottom wall, and side walls and a back wall directed upwardly along the opposite side and back margins, respectively, of said bottom wall to define a cavity which is open at the top for receiving a cassette and has an opening at the front of the housing extending substantially down to said bottom wall and through which access may be had to a cassette in the cavity for upwardly dislodging the cassette therefrom, and a top wall hingedly connected, at one end, to the top of said back wall for swinging between an upwardly directed opened position and a closed position in which said top wall extends between said side walls to close said cavity at the top of the latter, said top wall having a depending flange at the end thereof remote from its hinged connection to said back wall for closing said opening at the front of the housing in said closed position of the top wall; and means engageable in said closed position of the top wall for releasably holding the latter in said closed position.
Claim 3
Dependent Claim
30 words
A container according to claim 1; in which said housing and said means for releasably holding the top wall in its closed position are a unitary molding of plastic resin.
Claim 4
Dependent Claim
51 words
A container according to claim 1; in which said housing further has inwardly directed wall sections extending from the front ends of said side walls and delimiting said opening so as to prevent the forward discharge of a cassette from said cavity when said top wall is in its opened position.
Claim 5
Dependent Claim
48 words
A container according to claim 1; in which said means for releasably holding the top wall in said closed position includes pairs of projections extending from said bottom wall and top wall, respectively, and being frictionally engageable with each other in said closed position of the top wall.
Claim 6
Dependent Claim
30 words
A container according to claim 4; in which there are two of said pairs of projections located to extend through respective reel hubs of a cassette disposed in said cavity.
Claim 7
Dependent Claim
55 words
A container according to claim 5; in which each of said pairs of projections includes a female member defining an axially open socket and having a non-circular periphery for holding the respective reel hub of a cassette against rotation, and a male member which is frictionally engageable in said socket of the respective female member.
Claim 8
Dependent Claim
78 words
A container according to claim 1; in which one of said side walls has a groove of dovetail cross-section extending along its outer surface, and the other of said side walls has an elongated rail extending along its outer surface and having a dovetail cross-section similar to that of said groove so that a plurality of containers can be secured in side-by-side relation with said groove of one container slidably receiving said rail of the next adjacent container.
Claim 9
Dependent Claim
45 words
A container according to claim 7; in which said rail has a medial recess extending therealong so that the opposed edges of said rail can be flexed toward each other for facilitating the movement of said rail along the groove of a next adjacent container.
Claim 10
Dependent Claim
23 words
A container according to claim 8; in which said rail terminates short of the front and back ends of the respective side wall.
Claim 11
Dependent Claim
17 words
A container according to claim 9; in which said opposed edges of the rail have bevelled ends.
Claim 12
Dependent Claim
23 words
A container according to claim 7; in which said rail terminates short of the front and back ends of the respective side wall.
Claim 13
Dependent Claim
17 words
A container according to claim 7; in which the opposed edges of said rail have bevelled ends.
Claim 14
Dependent Claim
77 words
A container according to claim 7; in which said groove has a centrally located node therein, said rail has a medial recess extending therealong in which said node of a next adjacent container can travel when securing together a plurality of the containers, and a land is formed centrally in said recess with a socket in said land to receive said node of said next adjacent container for forward and backward alignment of the secured together containers.
Claim 15
Dependent Claim
182 words
A one-piece molded plastic container for a magnetic tape cassette comprising a rectangular housing having opposed side walls, one of said side walls having opposed side walls, one of said side walls having a groove of dovetail cross-section extending along its outer surface, the other of said side walls having an elongated rail extending along its outer surface, said rail having a dovetail cross-section that is complementary to said cross-section of the groove, said rail terminating short of the opposed ends of said other side wall so that, when a plurality of the containers are to be secured together in side-by-side relation, said one side wall of one container can be disposed against an end portion of said other side wall of another container, whereupon the containers can be longitudinally moved relative to each other to longitudinally slidably engage their respective rail and groove, and said rail having a medial recess extending therealong so that the opposed edges of said rail can be flexed toward each other for facilitating the movement of said rail along the groove of a next adjacent container.
