Abstract

Consumer products, e.g., shaving systems and toothbrushes, are disclosed which have a replaceable portion, e.g., a shaving assembly or a toothbrush head, that is removably mounted on a handle. The consumer products described herein include keyed structures on the handle and replaceable portion, the relative placement of which creates a unique interaction between the two parts. This unique interaction may, for example, be used to provide a dedicated attachment system for each specific customer of the manufacturer of the consumer product.

Claims (40)

1. A method for providing two or more shaving systems, each shaving system having a unique cartridge attachment, the method comprising:

providing a first shaving system comprising:

a handle having a distal end and a proximal end, and

a shaving assembly configured to removably interface with the handle,

wherein the distal end of the handle includes a keyed structure and the shaving assembly includes a complementary keyed structure, the keyed structures having a first configuration; and

providing a second shaving system comprising:

a handle having a distal end and a proximal end, and

a shaving assembly configured to removably interface with the handle,

wherein the distal end of the handle includes a keyed structure and the shaving assembly includes a complementary keyed structure, the keyed structures having a second configuration different from the first configuration, such that the shaving assembly of the first shaving system cannot be attached to the handle of the second shaving system

wherein in each of the shaving systems the handle includes a protrusion and the shaving assembly includes a cavity configured to receive the protrusion and the keyed structures are provided on the protrusion and within the cavity, and

wherein the complementary keyed structures comprise one or more channels or bores disposed on the protrusion, and one or more complementary ribs or pins disposed in the cavity and configured to be received in the channels or bores.

2. The method of claim 1 further comprising providing at least one of the shaving systems with a magnetic attachment system configured to retain the shaving assembly on the handle.

3. A method of removably attaching a shaving assembly to a handle, the method comprising:

providing a handle having a distal end and a proximal end,

the handle having a keyed structure at its distal end, and

mounting on the handle a shaving assembly configured to removably interface with the handle,

the shaving assembly having a keyed structure that is complementary with that of the handle,

wherein the handle includes a protrusion and the shaving assembly includes a cavity configured to receive the protrusion and the keyed structures are provided on the protrusion and within the cavity, and

wherein the keyed structures comprise one or more channels or bores disposed on the protrusion, and one or more complementary ribs or pins disposed in the cavity and configured to be received in the channels or bores.

4. The method of claim 3 wherein mounting comprises utilizing a magnetic attachment system to retain the shaving assembly on the handle.

5. A method of shaving comprising contacting the skin with the shaving assembly of a shaving system, the shaving system comprising a handle having a distal end and a proximal end, and a shaving assembly configured to removably interface with the handle, wherein the distal end of the handle includes a keyed structure and the shaving assembly includes a complementary keyed structure, and wherein the handle includes a protrusion and the shaving assembly includes a cavity configured to receive the protrusion and the keyed structures are provided on the protrusion and within the cavity, and the keyed structures comprise one or more channels or bores disposed on the protrusion, and one or more complementary ribs or pins disposed in the cavity and configured to be received in the channels or bores.

6. The method of claim 5 further comprising mounting the shaving assembly on the handle utilizing a magnetic attachment system.

7. A method for providing two or more shaving systems, each shaving system having a unique cartridge attachment, the method comprising:

providing a first shaving system comprising:

a handle having a distal end and a proximal end, and

a shaving assembly configured to removably interface with the handle,

wherein the distal end of the handle includes a keyed structure and the shaving assembly includes a complementary keyed structure, the keyed structures having a first configuration; and

providing a second shaving system comprising:

a handle having a distal end and a proximal end, and

a shaving assembly configured to removably interface with the handle,

wherein the distal end of the handle includes a keyed structure and the shaving assembly includes a complementary keyed structure, the keyed structures having a second configuration different from the first configuration, such that the shaving assembly of the first shaving system cannot be attached to the handle of the second shaving system

wherein the shaving assembly includes a protrusion and the handle includes a cavity configured to receive the protrusion and the keyed structures are provided on the protrusion and within the cavity, and

wherein the complementary keyed structures comprise one or more channels or bores disposed on the protrusion, and one or more complementary ribs or pins disposed in the cavity and configured to be received in the channels or bores.

8. A method of removably attaching a shaving assembly to a handle, the method comprising:

providing a handle having a distal end and a proximal end,

the handle having a keyed structure at its distal end, and

mounting on the handle a shaving assembly configured to removably interface with the handle,

the shaving assembly having a keyed structure that is complementary with that of the handle,

wherein the shaving assembly includes a protrusion and the handle includes a cavity configured to receive the protrusion and the keyed structures are provided on the protrusion and within the cavity, and

wherein the complementary keyed structures comprise one or more channels or bores disposed on the protrusion, and one or more complementary ribs or pins disposed in the cavity and configured to be received in the channels or bores.
