  • Patent number: 4257160
    Abstract: A two-bladed safety razor has a platform unitary with the handle of the razor. The platform movably supports a blade carrier plate which in turn fixedly carries a shaving blade unit including an upper blade, lower blade and a spacer member interposed between the upper and lower blades. A cap member overlying the upper blade is connected to the platform. Between the upper and lower blades, interposed is an ejecting member which is fixed to at least one of the cap member and the platform. Means are provided for causing a movement of the blade carrier plate and, hence, of the shaving blade unit to and from a fully retracted position relatively to the ejecting member. The ejecting member is so located that the cutting edge of the lower blade is positioned flush with or behind the front surface of the ejecting member when the blade assembly takes the fully retracted position.
