Abstract
Abstract A box, particularly for holding floppy discs, has an outer sleeve enclosing a drawer. The drawer can be withdrawn partially from the sleeve to a position where pins moulded inside the sleeve and sliding in grooves in the sleeve limit the withdrawal. The drawer and sleeve can then be swung with respect to each other and the drawer moved back on itself. The open box is self-supporting in this invert-V configuration.

Claim 1
Independent Claim
319 words
A box for holding thin objects, said box comprising: an outer part, including two opposite side members and a top member, a drawer, including two opposite side members and a bottom member, said side members of said outer part and said side members of said drawer being arranged in two adjacent pairs of one outer-part side member and one drawer side member per pair; engagement means for interconnecting said drawer and said outer part so as to allow said drawer to be at least partially withdrawn from said outer part to a position whence said drawer can be swung through an angle of less than 180 degrees with respect to said outer part and engage in a self-supporting open position; said engagement means comprising: a respective pin fixedly attached to one of each pair of side members so as to be positioned between its pair of side members, a respective groove or slot extending in the other of each pair of side members for co-operating with said respective pin to interconnect said drawer and said outer part, and a stop at an end of each groove or slot for stopping withdrawal movement of said drawer; a restraining member for restraining the objects from falling out of said box in its self-supporting, open position; pivotal connection means for pivotally connecting said restraining member to said drawer, the axis of pivotal connection positioned in said side members of said drawer; and pivotal limitation means for limiting forward pivotal movement of said restraining member so that said restraining member has a forwards inclination in its restraining position when said box is in its open, self-supporting position supported on a flat surface; said pivotal limitation means arranged so that a forward edge of said restraining member abuts the flat surface when in its restraining position with said box open, for steadying of said box against tipping forward under weight of the restrained objects.

A box for holding thin objects, said box comprising: an outer part, including two opposite side members and a top member, a drawer, including two opposite side members and a bottom member, said side members of said outer part and said side members of said drawer being arranged in two adjacent pairs of one outer-part side member and one drawer side member per pair; engagement means for interconnecting said drawer and said outer part so as to allow said drawer to be at least partially withdrawn from said outer part to a position whence said drawer can be swung through an angle of less than 180 degrees with respect to said outer part and engage in a self-supporting open position; said engagement means comprising: a respective pin fixedly attached to one of each pair of side members so as to be positioned between its pair of side members, a respective groove or slot extending in the other of each pair of side members for co-operating with said respective pin to interconnect said drawer and said outer part, and a stop at an end of each groove or slot for stopping withdrawal movement of said drawer; a restraining member for restraining the objects from falling out of said box in its self-supporting, open position; pivotal connection means for pivotally connecting said restraining member to said drawer, the axis of pivotal connection positioned in said side members of said drawer; and pivotal limitation means for limiting forward pivotal movement of said restraining member so that said restraining member has a forwards inclination in its restraining position when said box is in its open, self-supporting position supported on a flat surface; said pivotal limitation means arranged so that a forward edge of said restraining member abuts the flat surface when in its restraining position with said box open, for steadying of said box against tipping forward under weight of the restrained objects.
Claim 3
Dependent Claim
43 words
A box according to claim 1, wherein said engagement means includes a second stop in each groove or slot, said second stop being spaced from said respective first stop for stopping movement back of said drawer for engagement in its self-supporting, open position.
Claim 4
Dependent Claim
24 words
A box according to claim 2, wherein each second stop is so positioned that the movement-back distance is less than the original drawing distance.
Claim 5
Dependent Claim
61 words
A box according to claim 1, wherein a web of said restraining member having said forward edge cooperates with a top front edge of said drawer in an over-centre way during movement of said restraining member from a position partially closing said drawer when said box is closed to its surface abutting/restraining position for maintaining the restraining member in said position.
Claim 6
Dependent Claim
55 words
A box according to claim 1, wherein said restraining member includes a web and side members extending from said web inwardly of said drawer adjacent said side members of said drawer, each side member of said restraining member having a pin engaged in a respective aperture in a respective one of said drawer side members.
Claim 7
Dependent Claim
36 words
A box according to claim 5, wherein said drawer side apertures are slots extending transversely of the length of said drawer side members to permit transverse deflection of said pins on movement of said restraining member.

Claim 9
Dependent Claim
36 words
A box according to claim 6, wherein said restraining member is limited by abutment of a forward edge of each side member of said restraining member with the inside of a front member of said drawer.
Claim 10
Dependent Claim
54 words
A box according to claim 5, wherein said restraining member is resilient and provided with a detent for engaging in an aperture in a top member of said outer part for holding said box closed, said restraining member being flexed for disengagement of said detent from said aperture and for opening of said box.
Claim 11
Dependent Claim
25 words
A box according to claim 9, wherein said restraining-member side members abut said drawer on flexure of said restraining member for opening of said box.
