Patent Claims

What is claimed is:

1. A portable system for personal hygiene that comprises, in combination, a first compartment configured for containing at least one substrate, a second compartment configured for containing a solvent, wherein one or both compartments comprise a frangible region that can be opened or ruptured, wherein opening or rupturing the frangible region is adapted to allow the solvent to contact and absorb into the at least one substrate, where maintaining the frangible region is adapted to prevents the solvent from contacting the at least one substrate, and further comprising a member that is manually operable by user that opens or ruptures the frangible region, wherein the first compartment contains a first chemical reagent of an exothermic composition, and the second compartment contain a second chemical reagent of the exothermic composition, wherein combination of the two reagents generates heat, wherein the frangible region is configured, when opened or ruptured, to allow combination of the two reagents to create an exothermic reaction, and wherein at least one of the compartments contains a solvent, where the exothermic reaction increases the temperature of the solvent, and wherein the first compartment comprises a third compartment, or wherein the second compartment comprises a fourth compartment, wherein the third compartment is configured for containing the first chemical reagent, and the fourth compartment is configured for containing the second chemical reagent.

2. The system of claim 1, wherein the first compartment contains at least one substrate.

3. The system of claim 1, wherein the substrate is at least one absorbent towel.

4. The system of claim 1, wherein the first compartment does not contain a substrate.

5. The system of claim 1, wherein the second compartment contains at least one solvent.

6. The system of claim 1, wherein the solvent comprises water or an organic solvent, or a mixture of water and an organic solvent.

7. The system of claim 1, wherein the solvent comprises at least one fragrant compound, at least one anti-microbial compound, at least one dye, a combination of fragrant compound and anti-microbial compound, or any combination thereof.

8. The system of claim 1, wherein the solvent comprises at least one fragrant compound that is a child-oriented fragrant compound or an adult-oriented fragrant compound.

9. The system of claim 1, wherein the second compartment does not contain a solvent.

10. The system of claim 1, where the second compartment comprises a capsule, where the capsule is configured for containing the solvent.

11. The system of claim 1, wherein the system is configured so that, in use, the first chemical reagent, the second chemical reagent, and the exothermic combination do not touch or mix with the solvent and do not touch or absorb into the substrate.

12. The system of claim 1, wherein the second compartment that is configured for containing a solvent comprises at least one capsule, wherein the at least one capsule contains essentially all of the solvent that is comprised by the second compartment.

13. The system of claim 1, wherein the first compartment, second compartment, or both first and second compartments, comprise an adhesive strip or pull-cord that is operably linked to the frangible region, wherein in use, the adhesive strip or pull-cord opens or ruptures the frangible region.

14. The system of claim 1, wherein the first compartment and the second compartment are configured to define a chamber that is entirely in between the first and second compartments, wherein in use opening or rupture of the frangible region results in solvent leaving the second compartment for the chamber, and solvent in the chamber entering the substrate compartment.

15. A method for cleaning hands, comprising opening or rupturing the frangible region of the system of claim 1, allowing solvent to contact and absorb into the at least one substrate, withdrawing the at least one substrate from the system, and applying or wiping the at least one substrate to at least one hand that is in need of cleaning.

16. A method for eliciting a recall of a procedure for cleaning hands, or for motivating a child to clean his or her hands, comprising the method of claim 15, wherein the solvent comprises a child-oriented fragrant compound, wherein, in use, the fragrant compound is absorbed by the substrate, and wherein, in use, the fragrant compound that is absorbed by the substrate is detectable by a child holding the substrate at a distance of less than three inches from the child's own nose.

17. The method of claim 16, wherein the eliciting recall is measurable by a first test, and the motivating a child is measurable by a second test, wherein the first test or second test are one of a psychological test, behavioral test, electroencephalogram test, or brain magnetic resonance imaging (MRI) test.

18. The method of claim 15, further comprising warming the solvent prior to contacting or absorbing the solvent to the at least one substrate prior to the cleaning of hands, or warming the solvent-absorbed in the at least one substrate prior to the cleaning of hands.
