Abstract: In a safety razor a blade unit (1) is mounted on a carrying structure (2) for pivotal movement, and a delivery system (25,32,44) for conducting from a reservoir (21) a fluid, e.g. a lubricating fluid, which is to be applied to the skin during shaving, discharges the fluid at a port (45) which opens at or close to the pivot axis. The delivery system incorporates a valve (22,24) to control the supply of fluid to the blade unit (1) and the blade unit carrying structure (2) is coupled to the valve for the valve to eb actuated in response to the blade unit (1) being pressed against the skin during shaving. The blade unit carrying structured (2) is connected to a support structure (35) by a hinged coupling (36) and the valve is operated by a hinged movement of the blade unit carrying structure (2).

Abstract: A safety razor has a handle formed by a refillable container (8). After filling with water a tablet (20) containing a carbon dioxide gas generating substance is added to the water and the gas pressure is used to deliver liquid from the container to the underside of the razor blade unit (1). The tablet also includes a substance which upon being mixed with water produces a fluid which may have desirable properties for application to the skin during shaving, such as lubrication, moisturizing, applying a fragrance, chemical treatment of hairs, bacterial or medicinal treatment of the skin and/or blood coagulation. The container (8) can be equipped with a dispenser (30) operable to deliver tablets into the water filled container.

Abstract: A safety razor blade unit has a guard structure (5) which includes a strip (10) of elastomeric material e.g. with projections such as fins (12) or tubes (35), and a backstop (13) disposed between the elastomeric strip (10) and the edge (20) of a leading blade (2), the backstop including a rigid wall (15) integrally moulded with the blade unit housing (1) and a resiliently deformable portion (17) integral with the elastomeric strip (10) and adapted to yield under forces experienced during shaving by being compressed against the rigid wall (15) or flexing downwardly.

Abstract: A safety razor includes a suspension structure for supporting a blade unit (2) on a handle (1) so that the blade unit (2) is able to pivot about a longitudinal axis A and is able to move downwardly towards the handle (1), but is restrained from movement in a direction perpendicular to the permitted downward movement. The suspension structure includes a pair of arms (21) each including a rigid part (22) coupled between resilient parts (23 and 24). The free ends of the arms (21) carry pivot pins (15) and are interconnected by a strut (16) which may carry a leaf spring (18) to act on the underside of the blade unit to bias the blade unit to a rest position about the pivot axis.

Abstract: A safety razor blade unit includes a hair pulling member (7) located immediately in front of the cutting edge of a blade (6), the hair pulling member (7) having slots (10) through which the hairs pass defined by a series of elements (9). The edges of the elements (9) which define the slots (10) are formed to notch the hairs as they pass through the slots, and trailing end portions (14) of the elements (9) are inclined to guide the hairs to follow a path for pulling the hairs from the skin just before they are cut through by the blade.

Abstract: A novel cutting element in or for a safety razor comprises an elongate member with a series of slots (5), each slot (5) tapering from an open forward end to a substantially closed trailing end, and each slot (5) being confined between a pair of shaped edges (6) for slicing hairs as they move through the slot as the cutting element is moved across the skin. One or more of the cutting elements may be used in a safety razor blade unit, either alone or in combination with a blade having a conventional straight sharpened edge.

Abstract: A safety razor including at least one movable blade. The blade is moveable with respect to other parts of the razor. Movement of the blade increases the blade tangent angle in response to forces encountered during shaving.

Abstract: A plastic blister package for display and storage of a toothbrush has a base member and a closure member connected to one another by an integrally molded hinge. The base member and closure member have a pair of flanges, one overlying the other with package in the closed position, and a lip is provided on flange edge of the base member for receiving the edge of the closure member to seal the cavity formed by the two members. A pair of protuberances extend from the base flange and are received in interfitting engagement with a pair of openings found in the closure flange to substantially lock the package in the closed position.

Abstract: Extrusion apparatus is employed in a co-extrusion process to produce a triangular-shaped barrel for a writing instrument. An inner layer of material is extruded in tubular form having a substantially circular cross-section. A coating layer of three strips of material, equally spaced one from the other, is co-extruded about the outer periphery of the inner layer. A combination of forces produced during the process is effective to distort the inner layer to form a product having a substantially triangular shape.
