摘要： A disposable absorbent article having an expandable component. The expandable component can be inflatable, and includes a gas evolving material and an activating material separated from the gas evolving material by a breakable barrier. The barrier is broken to combine the materials and inflate the component at the point of use of the disposable absorbent article. The inflatable component can include a spacer for maintaining a fecal void space in a disposable absorbent article.

摘要： An absorbent article includes a liquid impervious backsheet joined to a liquid permeable topsheet with an absorbent core disposed therebetween. The joined topsheet and backsheet includes an extensible portion that is non-elastically, laterally extensible having a percent elongation of at least about 125%. A pair of elastomeric side panels is joined to a portion of the joined topsheet and backsheet near the extensible portion. Each of the side panels is elastically laterally extensible such that the force required to elongate the side panels a select percent elongation is less than the force required to elongate the extensible portion of the joined topsheet and backsheet an equivalent select percent elongation.
摘要翻译：吸收性物品包括与透液性顶片接合的不透液体的底片，其间设有吸收芯。接合的顶片和底片包括非弹性横向延伸的伸长部分，伸长百分比至少为约125％。一对弹性体侧片与可伸展部分附近的接合的顶片和底片的一部分接合。每个侧板弹性地横向延伸，使得拉伸侧板所需的力的选择百分比伸长率小于将连接的顶片和底片的可延展部分伸长的等效选择百分比伸长率所需的力。

摘要： Described herein is a multiple layer absorbent core having a front ear section, a crotch section and a back ear section, wherein the machine direction length of the crotch section equals the combined machine direction length of the front ear section and the back ear section, the angle and radii forming the transition from the crotch width to the ear width being equal, the core being suitable for use in an absorbent article, and a method for manufacturing such multiple layer absorbent core. The method comprises providing a single web of absorbent core material from a roll, in which the web having parallel straight longitudinal side edges; continuously transporting the web of absorbent core material in the machine direction; continuously cutting the web of absorbent core material longitudinally into web sections having at least one full-pattern strip having a repeating hourglass-shape and first and second side trim pieces each of the side trim pieces having a straight edge defined by one of the parallel straight longitudinal side edges of the web and an opposite non-linear longitudinal edge having a pattern corresponding to one of the longitudinal edges of the full-pattern strip; continuously orienting the side trim pieces relative to the full-pattern strip such that the ear sections and said crotch section of the side trim pieces are superimposed in registration with said full-pattern strip to form a continuous multiple layer composite strip; and successively cutting the composite strip in the transverse direction at predetermined intervals to form discrete multiple layer absorbent cores.

摘要： An absorbent article having an expandable component. The expandable component comprises a compressed, resilient element disposed within an air impermeable envelope. The compressed element provides the absorbent article with a thin, low bulk profile prior to use of the disposable absorbent article, thereby reducing shipping and storage space. At the point of use of the absorbent article, the air impervious envelope is opened, thereby permitting entry of air into the envelope and expansion of the compressed element. In one embodiment the expandable component is a spacer for maintaining fecal void space in a disposable diaper. Alternatively, the expandable component can provide displacement of the topsheet relative to the backsheet along the longitudinal centerline of a sanitary napkin.
摘要翻译：一种具有可膨胀组分的吸收制品。可膨胀部件包括设置在不透气外壳内的压缩弹性元件。在使用一次性吸收制品之前，压缩元件使吸收制品具有薄的低体积轮廓，从而减少运输和储存空间。在使用吸收性物品的时候，不透气的外壳被打开，从而允许空气进入外壳并膨胀压缩元件。在一个实施方案中，可膨胀组件是用于在一次性尿布中维持粪便空隙的间隔物。或者，可膨胀部件可以沿着卫生巾的纵向中心线提供顶片相对于底片的位移。
