摘要:
An absorbent article is provided that is comfortable and suitable for absorbing and containing liquid and solid body exudates without leakage. The absorbent article may be a diaper that includes a backsheet layer, a substantially liquid-permeable liner layer, and an absorbent core located between the backsheet and the liner. The backsheet generally defines a front waistband section, a rear waistband section, and an intermediate section, with the intermediate section interconnecting the front and rear waistband sections and disposed between laterally opposed side margins. The backsheet layer has at least one pleat adjacent each side margin that defines an expanded volume when the pleat expands, the expanded volume being greater than the volume when the pleat is unexpanded. The pleat is accessible to body exudates that pass through or around the absorbent core.

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.

The present disclosure relates to wet wipe dispensing systems for dispensing wet wipes capable of changing temperature upon use. In one embodiment, the dispensing system includes a wet wipe container and a lotion container that is held in assembly with the wet wipe container that contains a lotion that is kept separate from the wet wipes until the wet wipe is dispensed from the wet wipe container. The lotion includes a microencapsulated delivery vehicle that contains a temperature change agent that is capable of generating a temperature change upon contact with an aqueous solution. Once the wet wipe is dispensed from the system, an applicating device can apply the lotion to the wet wipe to facilitate contact between the temperature change agent in the microencapsulated delivery vehicle and the aqueous solution of the wet wipe.

Reactive chemistries for warming personal care products are disclosed. In one embodiment, one reactant of the chemistry is encapsulated in a microencapsulated composition. Upon rupture, the microencapsulated composition releases the reactant and the reactant can contact a second reactant in the reactive chemistry, located in either an aqueous solution or a second microencapsulated composition, generating heat. The reactants of the reactive chemistries may be introduced into wet wipes such that, upon activation, the wet wipe solution is warmed resulting in a warm sensation on a user's skin.
摘要:
Wiping products, such as facial tissues, contain a temperature change composition that can provide a cooling sensation when contacted with the skin of a user. The temperature change composition, for instance, can contain one or more phase change agents that undergo a phase change at slightly elevated temperatures. The phase change agents, in one embodiment, can have a relatively high heat of fusion. When undergoing a phase change, the phase change agents absorb heat and thereby provide a cooling feeling to the skin of a user. In one embodiment, the phase change agent comprises a straight chain hydrocarbon. Hydrocarbons useful as phase change agents include an octadecane, a nonadecane, a heptonoate, or mixtures thereof.
摘要:
The present invention relates to a personal care absorbent article comprising at least two substrates each having an internal and external surface, wherein at least one substrate is a fluid permeable bodyside substrate selected from spunbond, meltblown, coform, airlaid, bonded-carded web, spunlace materials and combinations thereof; at least one substrate is an impermeable backsheet; and an absorbent core disposed in between said substrates; wherein at least the external surface of at least one substrate has applied to it a benefit agent selected from an additive composition wherein said additive composition is a polymer dispersion selected from polyolefin dispersions, polyisoprene dispersions, polybutadiene-styrene block copolymer dispersions, latex dispersions, polyvinyl pyrrolidone-styrene copolymer dispersions, polyvinyl alcohol-ethylene copolymer dispersions, and combinations thereof; an enhancement component selected from microparticles, expandable microspheres, fibers, additional polymer dispersions, scents, anti-bacterials, moisturizers, medicaments, soothers and combinations thereof; and combinations thereof.
摘要:
Microencapsulated delivery vehicles comprising an active agent are disclosed. In one embodiment, the microencapsulated delivery vehicles are heat delivery vehicles capable of generating heat upon activation. The microencapsulated heat delivery vehicles may be introduced into wet wipes such that, upon activation, the wet wipe solution is warmed resulting in a warm sensation on a user's skin. Any number of other active ingredients, such as cooling agents and biocides, can also be incorporated into a microencapsulated delivery vehicle.
