In a dispensing system and process for dispensing a warm wet wipe, a wet has an aqueous solution and microencapsulated delivery vehicles including a temperature change agent capable of generating a temperature change upon contact with the aqueous solution. An activating device facilitates rupturing
In a dispensing system and process for dispensing a warm wet wipe, a wet has an aqueous solution and microencapsulated delivery vehicles including a temperature change agent capable of generating a temperature change upon contact with the aqueous solution. An activating device facilitates rupturing of the microencapsulated delivery vehicles as the wet wipe is removed from a wet wipe container to allow contact between the temperature change agent and the aqueous solution of the wet wipe to thereby dispense a warm wet wipe. In another embodiment the wet wipe in the container has an aqueous solution. A lotion having the microencapsulated delivery vehicles is disposed in a lotion container free from contact with the wet wipe. An applicator in communication with the lotion is operable to apply the lotion to the wet wipe while the wet wipe is disposed at least in part within the wet wipe container.

What is claimed is: 1. A dispensing system for dispensing a wet wipe, the dispensing system comprising: a container; a wet wipe disposed in the container, the wet wipe comprising an aqueous solution and microencapsulated delivery vehicles including a temperature change agent, the temperature change
What is claimed is: 1. A dispensing system for dispensing a wet wipe, the dispensing system comprising: a container; a wet wipe disposed in the container, the wet wipe comprising an aqueous solution and microencapsulated delivery vehicles including a temperature change agent, the temperature change agent being capable of changing the temperature of the wipe upon contact with the aqueous solution, the container being configured to permit removal of the at least one wet wipe therefrom; and an activating device configured to contact the wet wipe as the wet wipe is dispensed from the dispensing system, the activating device comprising a bearing surface and a roller in opposed, spaced relationship with the bearing surface to define a nip therebetween to facilitate rupturing of the microencapsulated delivery vehicles as the wet wipe is removed from the container, the spacing between the bearing surface and the roller being in the range of from about 0.1 mm to about 10 mm to apply a rupturing force to the microencapsulated delivery vehicles of the wet wipe in the range of from about 0.001 to about 250 pounds per linear inch, whereby the rupturing of the microencapsulated delivery vehicles allows for contact between the temperature change agent and the aqueous solution of the wet wipe to thereby dispense a wet wipe. 2. The dispensing system set forth in claim 1 wherein the activating device is removably connected to the container. 3. The dispensing system set forth in claim 1 wherein the bearing surface is formed integrally with the container. 4. The dispensing system set forth in claim 1 wherein the bearing surface is a roller. 5. The dispensing system set forth in claim 1 wherein the microencapsulated delivery vehicles comprise a core composition surrounded by an encapsulation layer, the core composition comprising a matrix material and a heating agent, and wherein the microencapsulated heat delivery vehicle has a diameter of from about 5 micrometers to about 5000 micrometers. 6. The dispensing system set forth in claim 5 wherein the matrix material is selected from the group consisting of mineral oil, isopropyl myristate, silicones, copolymers such as block copolymers, waxes, butters, exotic oils, dimethicone, thermoionic gels, plant oils, animal oils, and combinations thereof. 7. The dispensing system set forth in claim 5 wherein the heating agent is selected from the group consisting of calcium chloride, magnesium chloride, zeolites, aluminum chloride, calcium sulfate, magnesium sulfate, sodium carbonate, sodium sulfate, sodium acetate, metals, slaked lime, quick lime, glycols, and combinations thereof. 8. The dispensing system set forth in claim 1 wherein the micronencapsulated delivery vehicles comprise a substantially fluid-impervious microencapsulated delivery vehicle comprising a core composition, an encapsulation layer surrounding the core composition, and a moisture protective layer surrounding the encapsulation layer, wherein the core composition comprises a matrix material and a heating agent, and wherein the microencapsulated delivery vehicle has a diameter of from about 5 micrometers to about 5000 micrometers. 9. The dispensing system set forth in claim 1 wherein the microencapsulated delivery vehicles comprise a stabilized substantially fluid-impervious microencapsulated delivery vehicle comprising a core composition, an encapsulation layer surrounding the core composition, a moisture protective layer surrounding the encapsulation layer, and a fugitive layer surrounding the moisture protective layer, wherein the core composition comprises a matrix material and a heating agent, and wherein the microencapsulated delivery vehicle has a diameter of from about 5 micrometers to about 5000 micrometers. 10. The dispensing system set forth in claim 1 wherein the temperature change agent is a cooling agent. 11. A dispensing system for dispensing a wet wipe, the dispensing system comprising: a wet wipe container having an internal compartment for containing wet wipes; a wet wipe disposed in the internal compartment of the wet wipe container, the wet wipe comprising an aqueous solution; a lotion container having an internal compartment, separate from the internal compartment of the wet wipe container, for containing a lotion, a lotion contained within the internal compartment of the lotion container free from contact with the wet wipe in the wet wipe container, the lotion comprising microencapsulated delivery vehicles including a temperature change agent capable of changing the temperature of the wet wipe upon contact with aqueous solution; an applicator in communication with the internal compartment of the lotion container and operable to apply the lotion to the wet wipe while the wet wipe is disposed at least in part within the wet wipe container; and an activating device configured to contact the wet wipe as the wet wipe is dispensed from the dispensing system, the activating device comprising a bearing surface and an applicator roller in opposed, spaced relationship with the bearing surface to define a nip therebetween to facilitate rupturing of the microencapsulated delivery vehicles as the wet wipe is removed from the container, the spacing between the bearing surface and the applicator roller being in the range of from about 0.1 mm to about 10 mm to apply a rupturing force to the microencapsulated delivery vehicles in the lotion on the wet wipe in the range of from about 0.001 to about 250 pounds per linear inch, whereby rupturing of the microencapsulated delivery vehicles permits contact between the temperature change agent and the aqueous solution of the wet wipe to thereby dispense a wet wipe. 12. The dispensing system set forth in claim 11 wherein the applicator is operable to apply the lotion to the wet wipe as the wet wipe passes through the nip. 13. The dispensing system set forth in claim 11 wherein the bearing surface is a roller. 14. The dispensing system set forth in claim 11 wherein the lotion container is connected to the wet wipe container. 15. The dispensing system set forth in claim 14 wherein the lotion container is moveable relative to the wet wipe container to facilitate loading of the at least one wet wipe in the internal compartment of the wet wipe container. 16. The dispensing system as set forth in claim 11 wherein the microencapsulated delivery vehicles comprise a core composition surrounded by an encapsulation layer, the core composition comprising a matrix material and a heating agent, and wherein the microencapsulated delivery vehicles have a diameter of from about 5 micrometers to about 5000 micrometers. 17. The dispensing system as set forth in claim 16 wherein the matrix material is selected from the group consisting of mineral oil, isopropyl myristate, silicones, copolymers such as block copolymers, waxes, butters, exotic oils, dimethicone, thermoionic gels, plant oils, animal oils, and combinations thereof. 18.
