Abstract
ABSTRACT OF THE DISCLOSURE
A disposable razor including a blade package and a handle of the type having a permanently connected sliding blade cover operable to protect and expose the blade package selectively, in which a cover actuator is formed integrally with the cover and defines with the cover a single piece-part. The actuator is normally in contact with the handle while said blade package is protected by said cover, the handle providing a fulcrum for said actuator. The actuator is operable to rotate about said fulcrum and along said handle to develop sufficient mechanical advantage to move the cover to expose the blade package for wet shaving.

RAZOR WITH SLIDING COVER HAVING INTEGRAL ACTUATOR
BACKGROUND OF THE INVENTION
The present invention relates to disposable razors and relates in particular to razors of this class which are fitted with a movable, permanently attached blade cover which is movable selectively to expose or cover razor blade edges as desired.
Representative embodiments of razors over which this invention is an improvement are disclosed and claimed it the following US. Patents: 4,328,615t issued I 82 (Bowman, et at.); 4,425,705, issued 1-17-84 (Chin); and 4,476,630, issued 10-16-84 Byrne).
The '615 patent shows a cover 14 which makes a permanent but sliding connection with a blade support or seat 18 which is movable from a closed position in which blade edges are protected to an open position in which the blade edges are exposed properly for wet shaving.
The '705 patent shows a cover 14 making a similar connection with a razor body or blade support. Its dusting-wishing feature is a lever system supported pivotal in theorizer handle and makes a driving connection with the cover so that the cover is movable from the closed to the open position by manipulation of the lever in "one-hand" fashion.
The '630 patent shows an improved cover manipulator in the form of a slide or actuator 21 mounted in a track 17 in the razor handle. The slide makes a flexible connection with the cover so that motion of the slide along the track moves the cover along its track.
~$'' ~LZ~t342~
The use of the terms "blade", "blade package", "blade edge" or "blade cutting edges" in this specification is intended to include one or more blades each having a single cutting edge.
