Abstract

A packaging system for clutch sets. The system includes a box provided with several packing sheets of compressible foam which can be custom fitted to the clutch set components. The packaging system allows several sizes of clutch sets to be securely packaged in the same size box, and the compressible foam provides a lightweight means for stabilizing the components during shipping or storage. The outside of the box is unmarked except for a label on one side for a bar code or other information. The system includes a sleeve like wrapper with a hole in the side to reveal the label on the side on the box. The outside of the sleeve is imprinted with a brand name and other trade dress. This allows a bearing manufacturer to maintain an inventory of various sizes of pre-packaged clutch sets, along with an inventory of preprinted sleeves. Then, upon receipt of an order from a retail customer, the time necessary to complete the private label packaging of the clutch sets is substantially reduced. Moreover, because of the foam sheets, the boxes can be stored or shipped safely in stacks or on their sides.

Dependent claims

An assembly comprising:

a clutch cover having a diaphragm, a body portion extending upwardly and outwardly from the diaphragm to form a cavity, and a peripheral edge around the body portion;
a clutch disk having an edge;
a clutch bearing;
a box sized to receive the clutch cover, the clutch disk and the bearing, wherein the box has a bottom, a top and four sides, and wherein the top of the box is openable to permit access to the inside of the box;
a bottom sheet of foam sized to fit in the bottom of the box;
a center sheet of foam sized to fit in the box over the bottom sheet of foam, wherein the center sheet of foam has a central opening sized to receive the diaphragm of the clutch cover, wherein the diaphragm of the clutch cover is positioned therein, wherein the center sheet of foam has a corner opening sized to receive the bearing, and wherein the bearing is positioned therein;
a corner sheet of foam sized to have a portion which covers the bearing in the corner opening of the center sheet of foam and to have a flap sized to fit under the edge of the clutch disk, whereby the position of the bearing in the corner opening is at least partially secured by the corner sheet of foam while it is held in place by the edge of the clutch disk;
wherein the clutch disk is positioned to nest inside the body portion of the clutch cover;
and
a top sheet of foam sized to fit in the box over the bottom, center and corner sheets of foam and the clutch cover, clutch bearing and clutch disk assembled in the box.
