Abstract: A shaving razor includes one or more heaters held in spaced, adjacent relation to the rear non-cutting edge of at least one blade of the razor. The one or more heaters are in connection with an electric power source, which may be located in the blade cartridge or in the handle of the razor. When the electric circuit is closed and electric current flows through the heaters, the heaters generate heat that is directed between the blades and towards the front cutting edge of the blades in a radiator effect. The heaters serve to warm the blades while also providing warmth to the user's skin for increased shaving performance and comfort. In a preferred embodiment, the heaters are made from a high resistance material, such as Nichrome, for producing heat with maximum efficiency.

When supplied with electric current, the blades generate heat for increased shaving performance and comfort.

Abstract: A razor having a handle and a blade cartridge containing one or more blades includes an electric circuit with a battery power source for controlled direction of current flow through the one or more blades in order to heat the blades. The electric circuit further includes opposing electrically conductive contact leads, the battery power source, and an electrically conductive contactor in contact with an ON/OFF switch all housed on the blade cartridge. A housing for the battery and switch extends transversely in spaced and separated relation to the blades and defines a bridge structure over an open gap between the housing and the blades for allowing a directed stream of water flow to pass below the housing, through the gap and between the plurality of electrically conductive blades for rinsing debris from surfaces of the blades.

Abstract: A razor blade cartridge containing two or more blades includes an electric circuit with a battery power source for controlled direction of current flow through the blades in order to heat the blades. The blades are connected by at least one blade connector having electrically conductive contacts for electrically connecting the blades in a series arrangement, wherein flow of the electric current through the blades causes the blades to be heated.

Abstract: A method and system for regulating current flow in a wet shave razor includes one or more conductive materials, such as metals, in electric circuit connection, wherein each conductive material has unique resistance properties and is used to regulate the amount of current (i.e. heat) flowing to at least one electrically powered component on the blade cartridge, and particularly one or more electrically powered devices/elements on the blade cartridge such as, but not limited to, one or more blades, one or more heating elements, a vibration device, illuminating device (e.g. LED or bulb), gauges, or indicators. The length and thickness of the conductive materials used in the electric circuit further affects the total circuit resistance and, accordingly, the amount of current flowing to the blade cartridge for heating the blades. In other embodiments, the dissimilar material conductors may be used to regulate current flow to alternative electrically conductive components.

Abstract: A blade cartridge for a shaving razor contains a series of parallel blades and at least two contact segments as part of an electric circuit connected to the blades at spaced intervals to provide an electric current flow through the blades in a manner that provides more efficient heat distribution across the length of the blades. A radiator effect is created wherein heat produced by the contact segments passes between the blades towards the cutting edge of the blades. The combination of the heat produced by the electric current flow through the conductive blades and the heat produced by the contact segments provides a dual heat process that makes it easier to adjust and control the temperature to a desired stable heat temperature. A thin conductive film may be fitted to be in contact with the ends of the blades to insure conductivity throughout the entire length of each blade.

The blade heating system includes an electric circuit with a battery power source for controlled direction of current flow through the one or more blades in order to heat the blades. The electric circuit further includes an on/off switch, a visual indicator for indicating on/off status, a heat controller for selectively adjusting the temperature of the blades, and an automatic turn off switch for opening the circuit after an elapsed period or some action or non-action of physical movement of the razor for preserving battery life. In a preferred embodiment, all of the components of the electric circuit are housed on the blade cartridge, with the battery power source, switches and heat controller contained within a waterproof casing.

Abstract: A blade cartridge for a shaving razor contains a series of parallel blades, and at least two wire conductors of an electric circuit connected to the blades at spaced intervals to provide an electric current flow through the blades in a manner that provides more efficient heat distribution across the length of the blades. The ends of the blades may be held in place by staples that are insulated from the electric circuit. A thin conductive film may be fitted to be in contact with the ends of the blades to insure conductivity throughout the entire length of each blade. A radiator effect of the heated blades causes the blades to become warmer when the blades are placed against the skin surface and air is unable to circulate between the blades. The blades become less hot when removed from the skin and air circulates between the blades.

The indicator utilizes the weight of the opaque container in conjunction with a gel reservoir and capillary that is installed in a label. The label extends under the can subjecting the gel reservoir to pressure that results from the weight of the container rendering movement of gel in the capillary that with calibration is a direct representation of the amount of contents in the opaque container.

Abstract: An aerosol capacity indicator that utilizes a novel and inexpensive display that can be installed in the actuator of an aerosol can to display the amount of product remaining therein. The novel accumulative pressure indicator display is imbedded in the actuator which is attached to the valve of an aerosol can and activated by pressure applied directly by the user in the form of finger contact with the actuator. The total amount of pressure applied to the indicator and transferred to the aerosol valve by means of direct user contact both intermittent and continuous renders a relevant reading equivalent to the amount of product released from the aerosol can without any contact with the actual dispensed material.

Abstract: A shaving system which provides a continuously heated blade cartridge throughout the shaving stroke is attained by applying a measured amount of electric current to the blade cartridge by means of conductors connected on each side of the blade cartridge and extended in the form of contacts built into the docking end of the cartridge. The electric current is provided by a primary battery which is contained in a waterproof compartment in the shaver handle. The current provided by the battery renders opitimum heat generation in the blades in the cartridge and can be adjusted by means of resistors in series with the battery and the blade cartridge. In order to preserve the battery life, a momentary contact switch can be installed in the shaver handle which enables the user to press and hold the switch only during the shaving stroke. In the alternative, the shaving handle may also contain a rechargeable battery which can be continuously charged by storing the shaver handle in a charging stand.

Abstract: A battery charge indicator is disclosed which accurately displays the true state of charge or energy remaining in an alkaline battery in which the indicator is installed. An alkaline battery cell utilizes a steel can which contains the active chemical ingredients within and provides the conductive surface for the cathode. When the battery is sealed at the open end with a combination plug and anode, the closed end of the steel can becomes distorted or bulged due to internal pressures which are caused by both the expansion of the cathode material due to electrical discharge of the battery and hydrogen gas which accumulates during shelf life in storage. An increase the amount of hydrogen gas occurring during storage creates a distortion or bulge in the center of the closed end of the can. When the battery has been electrically discharged, the cathode material physically expands inside the can causing distortion to extend to the outer periphery of the closed end of the can.

Abstract: A battery charge indicator is disclosed which is permanently incorporated into a battery to indicate the state of charge. The indicator includes a compressible chamber such as a blister which is adapted to be installed in a battery as an assembly. The blister chamber is filled with a viscous gel and is exposed to the expandable cathode of the battery. As the battery discharges, the cathode expands thus causing the gel within the chamber to be extruded out through an outlet into a viewing channel in an overlying disk. The amount of gel flowing into the viewing channel is proportional to the amount of expansion of the cathode and, thus, indicates the amount of discharge and, conversely, the remaining life of the battery. A battery charge indicator is also disclosed in which the expansion of the cathode is adapted to apply localized pressure to a disk. The localized pressure applied to the disk causes stretching of the material of the disk, which causes a visual indication of the state of charge of the battery.
