摘要:
An absorbent article comprising an absorbent core having at least two longitudinally extending channel-forming areas and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid the core wrap forms channels along these areas substantially free of absorbent material. The wetness indicator is placed between the channel-forming areas or between at least one channel-forming area and at least one longitudinally extending side edge of the article, as seen for the exterior of the article.

Provided is a paper diaper which is safe to a wearer thereof and also has additional values of, for example, developing a plurality of colors and providing a practical effect of instantaneously detecting that the wearer has urinated, or the like. In a paper diaper 11 including a back sheet 13 for covering an outer side of an absorption body 14 for absorbing urine, an indicator portion 15 containing a colorless color-developing agent formed of an electron-donating coloration compound is formed by application on a wide range of an inner surface of the back sheet 13, and a color development assisting agent 16 is provided on the indicator portion 15. The color development assisting agent 16 is dissolved in the urine to contact the indicator portion 15, thus to cause the indication portion 15 to develop a color.
摘要:
An absorbent article of the present invention may comprise a backsheet, a wetness indicator composition, and an absorbent core. The wetness indicator composition may comprise a stabilizer, a colorant, and a matrix. The absorbent core may comprise a nonwoven layer and an absorbent polymer material, and optionally, a thermoplastic adhesive material. The wetness indicator composition may be in direct contact with an inner surface of the backsheet and an outer surface of the nonwoven layer. And, the absorbent polymer material, and optionally, the thermoplastic adhesive material, may be in direct contact with an inner surface of the nonwoven. Further, the absorbent core may be substantially cellulose free and may be oriented in at least one row.

An absorbent article includes a topsheet layer, a backsheet layer and one absorbent core layer. The topsheet layer, absorbent core layer and backsheet layer each include a longitudinally directed side peripheral edge. The absorbent article further includes an aqueous medium-sensitive coating composition for triggered release of active ingredients from the absorbent article. The aqueous medium-sensitive coating composition is affixed to the absorbent article adjacent a longitudinally directed side peripheral edge. The coating composition includes a betaine ester or betaine ester derivative having a functional active group derived from a fragrance with a hydroxyl group, a color changing visual indicator chemistry, where the visual indicator chemistry is selected from at least one of the group of a pH indicator dye and pH adjuster, a thermochromic dye and a polarity-sensitive dye.

The present invention relates to disposable absorbent articles. The disposable absorbent articles include: (a) a body contacting surface; (b) a garment contacting surface opposite the body contacting surface; and (c) an inkjet printed wetness indicator which is seen through either the body contacting surface or the garment contacting surface. The wetness indicator includes a central graphic and a background graphic, the central graphic having at least one permanent ink composition and the background graphic having at least one water soluble ink composition.
摘要:
A system for detection and monitoring of body exudates includes an absorbent article and at least one gas emitting substance incorporated within the absorbent article that can emit a gas after a liquid insult. After an insult, a device incorporating at least one gas sensitive composition can detect the gas and signal that an insult has occurred. The gas may also be detected by a non-contact gas sensor linked to a controller and signaling device which can send visual, auditory, and/or vibratory alerts. The alerts may be perceptible in an area outside the wearer's clothing or at a remote location, such as a watch, radio, computer device and/or smart phone. The system can also determine the fullness of an absorbent article and monitor dry time. The system can be used for interactive toilet training or for caring for an infant, a disabled person, an incontinent youth, or an elderly person.
摘要:
The present subject matter relates to absorbent articles and signaling devices for use therewith. The signaling device includes one or more non-invasive sensors configured to detect the presence of a substance, such as a body fluid, in the absorbent article. The signaling device can provide an audible and/or visible alert to the user of the absorbent article when it detects the presence of a substance. The absorbent article includes one or more identifiable characteristics the presence of which permits operation of the signaling device. In this manner, the present disclosure provides for product and signaling device matching for use.

The present disclosure relates to a color-changing composition and to a substrate having the color-changing compositions disposed thereon. The color-changing composition includes a leuco dye, a color-developer and a desensitizer. The color-changing composition changes from a colorless or largely colorless composition to color upon being wetted with an aqueous liquid. The color-changing composition remains colorless or largely colorless prior to exposure to high relative humidity conditions.
摘要:
An absorbent article including features facilitating toilet training of a wearer is provided. The article includes at least a first appearing graphic that changes from an initial, less visible state to a subsequent, more visible state in the absence of wetness, thereby to provide positive encouragement to a child during toilet training. The appearing graphic becomes less visible if subjected to liquid. A wetness sensation member may also be provided to give tactile, negative sensation to the child, thereby giving feedback received by at least two different senses. Additionally or alternatively, a second appearing graphic, different from the first appearing graphic, may be provided to increase a child's interest in the toilet training process. The first and second appearing graphics may become visible at different times, thereby providing a sequential or spaced reveal of the image.
