Adapter for a handle and a cartridge of different razor systems

1. An adapter for coupling between a razor handle and a razor cartridge together, the adapter being a separate component from said razor handle and said razor cartridge, the adapter comprising:

a handle engaging portion comprising:

at least one wall that defines a receptacle for receiving the razor handle;

a first handle protrusion extending from the at least one wall; and

a second handle protrusion extending from the at least one wall and being spaced from the first handle protrusion;

wherein the first handle protrusion and the second handle protrusion are inside the handle engaging portion and configured to engage a first recess and a second recess, respectively, of the razor handle;

a cartridge engaging portion coupled with the handle engaging portion, the cartridge engaging portion comprising:

a stem that defines a first recess and a second recess for selectively engaging a first cartridge protrusion and a second cartridge protrusion of the razor cartridge;

a tongue member slidably coupled with the stem and configured to contact the razor cartridge.

2. The adapter of claim 1 wherein the at least one wall comprises an upper wall and a lower wall and the first handle protrusion and the second handle protrusion extend from the lower wall.

3. The adapter of claim 2 wherein the first handle protrusion and the second handle protrusion are spaced apart by a distance that substantially the same as a distance between the first recess and the second recess of the razor handle.

4. The adapter of claim 2 further comprising a blocking portion that extends between a pair of engagement portions extending from the lower wall.

5. The adapter of claim 4 wherein the blocking portion extends higher than the pair of engagement portions relative to the lower wall.

6. The adapter of claim 1 further comprising a push member slidably coupled with the cartridge engaging portion and slidable between a retracted position and an extended position wherein sliding the push member from the retracted position to the extended position facilitates ejection of a cartridge from the stem.

7. The adapter of claim 6 further comprising a biasing member coupled with the tongue member and configured to bias the tongue member into an extended position.

8. The adapter of claim 7 wherein the biasing member is further coupled with the push member and is configured to bias the push member into the retracted position.

9. The adapter of claim 6 wherein the push member is substantially U-shaped.
