Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
In a disposable wet shaving razor of the type having a guard bar, a permanently attached cover overlaying the razor and slidable relative to the guard bar along a first track defining a first line of action from a first position in which the relationship between the cover and the guard bar renders the razor operable to a second position in which the relationship between the cover and the guard bar renders the razor inoperable, a mechanism for driving the cover relative to the guard bar comprising a slidable operating button, a flexible element connecting the cover to the button and a second track defining a second line of action for guiding the button so that sliding motion of the operating button along the second track drives the cover selectively along the first track to said first and second positions, said flexible element curving from said first line of action to said second line of action, said cover, said flexible element and said operating button being fixed together to define a unitary assembly and said tracks being substantially perpendicular to one another.
Claim 2
Dependent Claim
182 words

Claim 3
Dependent Claim
163 words
In a disposable wet shaving razor of the type having a body portion with a guard bar for supporting a fixed blade including a permanently attached slidable blade cover, said body portion terminating in a handle, said handle being disposed generally perpendicular to the blade and blade cover, a mechanism for actuating the cover relative to the body portion and the guard bar along a first line of action comprising a slidable operating button carried by the handle making a flexible connection with the cover and track means defining a second line of action in the razor handle for engaging and guiding the button such that sliding motion of the button along the handle slides the cover along the body portion relative to the guard bar and blade, said flexible connection curving from said first line of action to said second line of action through at least 90 degrees and said cover, said flexible connection and said operating button defining a unitary assembly.
Claim 4
Dependent Claim
163 words
In a disposable wet shaving razor of the type having a body portion with a guard bar for supporting a fixed blade including a permanently attached slidable blade cover, said body portion terminating in a handle, said handle being disposed generally perpendicular to the blade and blade cover, a mechanism for actuating the cover relative to the body portion and the guard bar along a first line of action comprising a slidable operating button carried by the handle making a flexible connection with the cover and track means defining a second line of action in the razor handle for engaging and guiding the button such that sliding motion of the button along the handle slides the cover along the body portion relative to the guard bar and blade, said flexible connection curving from said first line of action to said second line of action through at least 90 degrees and said cover, said flexible connection and said operating button defining a unitary assembly.
Claim 5
Dependent Claim
160 words
In a disposable razor of the type including a body portion, a handle, a fixed blade having a cutting edge, a guard bar fixed to the body portion and a permanently attached blade cover slidable along a first line of action attached to the body portion and overlaying the blade, a mechanism for driving the cover comprising a slidable operating button having opposed fins, a flexible element connecting the cover and the button and a track formed in the handle defining a second line of action cooperating with the fins for guiding the button and the flexible element so that sliding motion of the operating button along the track slides the cover along the body portion to cover the cutting edge to render the cutting edge inoperative while the flexible element traverses both lines of action, said cover, said flexible element and said operating button defining a unitary assembly and said lines of action being substantially perpendicular to one another.
Claim 6
Dependent Claim
160 words
