摘要： The present invention provides a disposable absorbent article such as an incontinent pad that is both comfortable and suitable for absorbing and containing large volumes of body liquids rapidly without leakage, especially a subsequent gush of liquid. Such an absorbent article comprises a liquid pervious topsheet, a liquid impervious backsheet, a layered expandable absorbent core positioned between the topsheet and the backsheet, at least two resilient shaping members, an acquisition channel, a liquid acquisition zone and at least two liquid impervious shelves. The present invention also relates to an absorbent article provided with an expandable overwrap having an expansion means for allowing the overwrap to expand when the absorbent core swells when wetted.The overwrap of the absorbent article is provided with an expansion means for permitting the overwrap to expand as the absorbent core swells when it is wetted. The expansion means is a releasable tack or other means that releases the overwrap when a slight shearing or peeling force or action is applied to the expansion means. Thus the swelling of the absorbent core is less likely to deform the shape of the pad or cause a loss of the absorptive capacity of the article, especially for subsequent gushes of liquids.
摘要翻译：本发明提供一种一次性吸收制品，例如失禁垫，其舒适并且适合于快速吸收和容纳大量体液，而不会有渗漏，特别是随后的液体流出。这种吸收制品包括液体可透过的顶片，液体不可渗透的底片，位于顶片和底片之间的分层可膨胀吸收芯，至少两个弹性成形构件，采集通道，液体采集区和至少两个不透液体的架。本发明还涉及一种具有可膨胀外包裹层的吸收性物品，其具有当吸湿芯在润湿时膨胀时允许外包层膨胀的膨胀装置。吸收制品的外包装设置有膨胀装置，用于当吸湿芯被润湿时吸收芯膨胀，允许外包装膨胀。膨胀装置是当将轻微的剪切或剥离力或作用施加到膨胀装置时释放外包装的可释放的粘性或其它方式。因此，吸收芯的膨胀不太可能使垫的形状变形或引起制品的吸收能力的损失，特别是对于随后的液体冲击。

摘要： The present invention provides a disposable absorbent article such as an incontinent pad that is both comfortable and suitable for absorbing and containing large volumes of body liquids rapidly without leakage, especially a subsequent gush of liquid. Such an absorbent article comprises a liquid pervious topsheet, a liquid impervious backsheet, a layered expandable absorbent core positioned between the topsheet and the backsheet, at least two resilient shaping members, an acquisition channel, a liquid acquisition zone and at least two liquid impervious shelves. The present invention also relates to an absorbent article provided with an expandable overwrap having an expansion means for allowing the overwrap to expand when the absorbent core swells when wetted. The liquid impervious shelves comprise a multiplicity of shelf layers formed from a portion of the backsheet being folded. The liquid impervious shelves channel the flow of liquids toward the lower layers of the absorbent core and encourage use of the bottom and sides of the layers, thereby providing more efficient use of hydrogel materials. An anti-bunching bead may be placed one each liquid impervious shelf between the shelf layers to provide stability to the absorbent article.
