Heated cleaning articles using a reactive metal and saline heat generator
First Claim
1. A selectively heatable cleaning article comprising:
- (a) a cleaning substrate material comprising one or more layers;
(b) a heat engine comprising a reactive metal composition that generates heat upon contact with a salt water composition;
(c) a handle attachable to the cleaning substrate, the handle including a delivery channel therethrough in fluid communication with the reactive metal composition of the heat engine so that upon introduction of an activating water composition through the delivery channel, the heat engine is activated, generating heat; and
(d) a venting structure surrounding or adjacent to the heat engine comprising a moisture impermeable material containing one or more vents through at least one surface of the moisture impermeable material for releasing steam and/or water vapor generated by the heat engine, so that the venting structure directs the water vapor and/or steam through the one or more vent holes on one face of the cleaning article, opposite a face on which the handle is attachable.

Abstract
Cleaning articles including a heat engine incorporated therein. The cleaning article may include a substrate (e.g., a non-woven wipe) including one or more layers. The heat engine may be in the wipe or pad, and includes a reactive metal composition which upon contact with a salt water (e.g., saline) composition, reacts to produce heat. The cleaning article may thus produce water vapor and/or steam upon activation of the heat engine. A venting structure may be provided adjacent to or surrounding the heat engine that includes an impermeable material (e.g., impermeable to water and/or air or other gas), which includes one or more vents through the impermeable material. The venting structure directs water vapor and/or steam to a desired face of the cleaning article, away from the user. A heat barrier layer may insulate a user'"'"'s hand from the generated heat, and/or a handle may be attachable to the pad.

9. A selectively heatable cleaning article comprising:
-
(a) a cleaning substrate material comprising one or more layers; (b) a heat engine comprising; (i) a reactive metal composition; (ii) water provided in a frangible, moisture impermeable container; (iii) a salt; (c) a venting structure surrounding the heat engine comprising a moisture impermeable material containing one or more vents on at least one surface of the impermeable material for releasing steam and/or water vapor generated by the heat engine. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A selectively heatable cleaning article comprising:
-
(a) a cleaning substrate material comprising one or more layers; (b) a heat engine comprising; (i) a reactive metal composition; and (ii) a salt, wherein upon addition of water to the heat engine, forms a salt water composition and a heating reaction between the reactive metal composition and the salt water composition is initiated; (c) a venting structure surrounding the heat engine comprising a moisture impermeable material containing one or more vents through at least one face of the impermeable material, so as to direct water vapor and/or steam generated by the heat engine to exit from the cleaning article from a face thereof; and (d) a heat barrier layer on a face opposite from where the water vapor and/or steam generated by the heat engine exits the cleaning article, to allow a user to hold the cleaning article on the face including the heat barrier layer while reducing risk of a burn. - View Dependent Claims (18, 19)
