Abstract: One embodiment provides a method of treating the skin or body part, comprising contacting the skin or body part with a composition; and contacting the composition and heating and/or cooling the skin or body part with a thermoelectric Peltier device. Another embodiment provides a skin care kit, which comprises a composition suitable for application to the skin; and a thermoelectric Peltier device configured to contact the composition and to heat and/or cool the skin. Other embodiments are also disclosed.

Abstract: A spraying device (10) includes a compound fourway rotatable control valve (30), an additive fluid control disc member (84) and a spray selector disc member (104), whereby a primary fluid, such as water, and an additive fluid, such as detergent, can be sprayed or dispensed in various spray patterns separately, or as a mixture having selectively variable concentrations of the additive fluid in the primary fluid. The compound fourway rotatable valve 30 is movable from an inoperative "OFF" position into first, second and third "WATER RINSE", "SOAP-AND-WATER" and "SUDS ONLY" operative positions. The control disc member (84) includes a plurality of orifices (86) of various diameters for controlling the amount of additive fluid dispensed into the primary fluid from a resilient bladder (16) containing the additive fluid as the bladder is collapsed in response to external pressure thereon by the primary fluid.

Abstract: A spraying device comprising a spray tube having a fluid entrance end connectable to a primary fluid source, and a fluid exit end upon which an additive fluid dispenser is removably mounted. The additive fluid dispenser, having a chamber for holding additive fluid and a mixing chamber, is coupled to the fluid exit end of the spray tube in coaxial alignment with the direction of flow of primary fluid through the spray tube, causing opening of a valve mechanism in the fluid dispenser. The additive fluid then is metered into the primary fluid flowing through the dispenser, by diverting a portion of the primary fluid flow against a movable piston on a piston guide member-primary fluid conduit, to cause flow of the additive fluid through the valve mechanism. The spray tube may be of elongated telescoping construction, or of nontelescoping construction, and may include a control valve.
