Shipper with tooth design for improved loading
View Patent ↗A shipper for memory disks comprises a cassette having an open top and an open bottom, a top cover to cover the open top, and a bottom cover to cover the bottom. The body portion has opposing side walls and opposing end walls. The two side walls each have with a vertical upper portions and an inwardly converging bottom portion. Said sidewalls have inwardly facing elongate teeth or spacers defining slots to hold the substrates in a vertically positioned and spaced array. Each tooth is continuous from the open top to the open bottom and each tooth has a upper vertical portion at the vertical upper portion of the side wall and a converging lower portion at the bottom portion of the side walls. The converging lower portion of each tooth follows the convergence of the bottom portions of the sidewalls. The converging lower portion of each tooth is configured to be different than the configuration of the tooth at the upper portion providing for improved performance in receiving disks to minimize or eliminate the incomplete receipt of disks in the slots such as by the disks catching and resting on the top of the teeth.
1. A disk shipper for shipping memory disks, the shipper comprising a cassette having opposing side walls and opposing end walls, an open top, and an open bottom,
a top cover to cover the open top,
a bottom cover to cover the bottom
the two side walls of the cassette each having a vertical upper portion and an inwardly converging bottom portion, said sidewalls have a plurality of inwardly facing elongate teeth defining slots to hold the substrates vertically positioned and in a spaced array, each tooth being continuous from adjacent to the open top to adjacent the open bottom, each tooth having an upper portion at the vertical upper portion of the side wall and a converging lower portion at the converging bottom portion of the side walls, in cross-section each tooth having an apex and wherein the sharpness of the apex increases towards the open bottom and being at a maximum sharpness directly adjacent the open bottom.
2. The disk shipper of claim 1 wherein in cross-section each tooth has a length and wherein the length of the tooth increases to maximum at the open bottom.
3. The disk shipper of claim 1 wherein the plurality of teeth of each sidewall comprise a plurality of adjacent pairs defining disk receiving slots and wherein each slot has a width and wherein the width of each slot increases as the teeth approach the open bottom.
4. A disk shipper for shipping memory disks, the shipper comprising a cassette having opposing side walls and opposing end walls, an open top, and an open bottom,
a top cover to cover the open top,
a bottom cover to cover the bottom
the two side walls of the cassette each having a vertical upper portion and an inwardly converging bottom portion, said sidewalls have a plurality of inwardly facing elongate teeth defining slots to hold the substrates vertically positioned and in a spaced array, each tooth being continuous from adjacent to the open top to adjacent the open bottom, each tooth having an upper portion at the vertical upper portion of the side wall and a converging lower portion at the converging bottom portion of the side walls, the teeth defining a plurality of slots and wherein the teeth are configured to expand the slot as the teeth approach the open bottom thereby providing an enlarged receiving area for the disks during insertion.
5. A disk shipper for shipping memory disks, the shipper comprising a cassette having opposing side walls and opposing end walls, an open top, and an open bottom,
a top cover to cover the open top,
a bottom cover to cover the bottom
the two side walls of the cassette each having a vertical upper portion and an inwardly converging bottom portion, said sidewalls have a plurality of inwardly facing elongate teeth defining slots to hold the substrates vertically positioned and in a spaced array, each tooth being continuous from adjacent to the open top to adjacent the open bottom, each tooth having an upper portion at the vertical upper portion of the side wall and a converging lower portion at the converging bottom portion of the side walls, each tooth having a tooth radial height profile that is concentric with the circumference of the disks beginning at the juncture between the upper portion of each tooth and the lower converging portion of each tooth and then has an increasing height profile corresponding to a decreasing radius as the tooth approaches the open bottom.
6. A disk shipper for shipping memory disks, the shipper comprising a cassette having opposing side walls and opposing end walls, an open top, and an open bottom,
a top cover to cover the open top,
a bottom cover to cover the bottom
the two side walls of the cassette each having a vertical upper portion and an inwardly converging bottom portion, said sidewalls have a plurality of inwardly facing elongate teeth defining slots to hold the substrates vertically positioned and in a spaced array, each tooth being continuous from adjacent to the open top to adjacent the open bottom, each tooth having an upper portion at the vertical upper portion of the side wall and a converging lower portion at the converging bottom portion of the side walls, in cross-section each tooth having an apex and wherein the radius defining the apex decreases towards the open bottom and being at a minimum radius adjacent the open bottom.
7. The disk shipper of claim 6 wherein the plurality of teeth of each sidewall comprise a plurality of adjacent pairs defining disk receiving slots and wherein each slot has a width and wherein the width of each slot increases as the teeth approach the open bottom.
