摘要： A plastic safety razor has a body formed of a head and a handle molded in one piece of resilient plastic material. The head is molded with a thin slot open at the front of the head and at opposite ends of the head, and the face walls of the slot are spaced apart by the thickness of a blade adapted to be held within the slot. The slot is closed by a back wall which forms a rear abutment for a single edge blade held in the head. The blade has blunt edges at the extremities of its sharpened edge and is pushed endwise into the slot and by engagement with the blunt edges is seated rearwardly against the back abutment wall of the slot.

摘要： A pair of identical fastener elements are arranged in superposed, face-to-face relation to cooperatively define a plurality of elongated, peripherally enclosed channels for passage of end portions of strips of material which are thereby joined by the fastening arrangement. Each element has a plurality of arms extending from a connection at one end with a central body portion to a free end, with opposing, spaced edges of the arms and body portions forming slots closed at one end and open at the other. Placing two of the elements in face-to-face, superposed relation with the arms of each element overlying the opposite end of the arms of the other element provides the peripherally enclosed channels. The fastening elements are disclosed in a number of configurations.
