## Abstract

A wet shaving cartridge having at least two blades, a movable fin between blades for purging shaving debris and a slidable, permanently connected protective blade cover with a driving connection between the cover and the fin such that motion of the cover moves the fin.

## Claims

### Claim 1

A razor blade cartridge having at least two spaced blades having cutting edges, a movable member or fin sandwiched between the blades for purging the blades of shaving debris, a cap connected permanently to the blade cartridge and movable to and fro relative to the cartridge and means making a driving connection between the cap and said movable member operative to drive said movable member whenever the cap is moved in a predetermined direction.

### Claim 2 (depends on 1)

The device of claim 1 in which the means making the driving connection define a pin and a cooperating link.

### Claim 3 (depends on 2)

The device of claim 2 in which the pin projects from the cap and engages an elongated link formed in the movable member.

### Claim 4 (depends on 3)

The device of claim 3 in which the link is fashioned with sufficient elongation to permit motion of said movable member independently of the motion of said cap.

### Claim 5 (depends on 4)

The device of claim 4 in which said movable member is molded integrally with a fixed spacer.

### Claim 6 (depends on 5)

The device of claim 5 in which the movable member is formed with a tab for digital operation.

### Claim 7

A razor blade cartridge having at least two spaced blades having cutting edges, a movable member or fin sandwiched between the blades for purging the blades of shaving debris, said fin having an operating tab, a cap connected permanently to the blade cartridge and movable to and fro relative to the cartridge, said cap having an opening facilitating access to said operating tab whereby said fin is movable independently of said cover.
