摘要:
An absorbent article, such as a sanitary napkin, having flaps with a combination of first and second stress relief means for relieving the stresses that develop in the flaps when the flaps are folded down along the edges of the wearer's panties in the crotch. The flaps extend laterally outward from the main body portion of the article. The flaps are associated with the main body portion at a juncture along the longitudinal edges of the main body portion. The flaps have a first stress relief means located remote from the juncture. The first stress relief means can be either a slit or a notch. The flaps have at least one second stress relief means contiguous with the first stress relief means. The second stress relief means is a zone of differential extensibility. The zone of differential extensibility can be capable of greater extension in a generally longitudinal direction than other portions of the absorbent article. The zone of differential extensibility can be made of corrugated or ring-rolled portions of the absorbent article.

Containment flaps comprising an elastic member and a resilient member are disclosed. When employed in a disposable absorbent article, the resilient member is adapted to be disposed between the elastic member and the body surface of the wearer of the disposable absorbent article. The resilient member serves to help make the containment flaps more comfortable for the wearer, and can help the flap better conform to contours associated with the body surfaces with which the containment flap comes into contact.

An absorbent article such as a sanitary napkin, adult incontinence device, or the like. The absorbent article has a pair of flaps for securing the absorbent article. The flaps extend laterally outward from the main body portion of the article. The flaps are associated with the main body portion at a juncture along the longitudinal edges of the main body portion. The flaps have a notch. The flaps have at least one first zone of anisotropic stiffness contiguous with the notch. The first zone of anisotropic stiffness has a relatively stiffer direction and a relatively less stiff direction. The first zone of anisotropic stiffness can be made of corrugated or ring-rolled portions of the absorbent article.
摘要:
A sanitary napkin is described, which includes a substantially planar and elongate body defining two larger longitudinal side edges. The body is provided with a garment faceable outer layer of liquid impermeable material, a body faceable cover layer of liquid permeable material, an absorbent core inserted into the body between the outer layer and the cover layer, and at least one substantially protuberant flexible flap substantially projecting outwards from each longitudinal side edge of the body, the flap being substantially transparent and/or translucent.

Disclosed is a sanitary napkin having extensions. The sanitary napkin includes: a liquid-permeable topsheet disposed on one side of the sanitary napkin to cover a central region thereof; a backsheet; an absorbent layer disposed therebetween; and leakage preventing portions disposed on laterally opposed side portions of the topsheet and extending in a longitudinal direction of the sanitary napkin. Joints between the respective leakage preventing portions and the topsheet are formed to extend in the longitudinal direction. The extensions are portions of the sanitary napkin extending laterally outwardly beyond the joints. Each extension includes: a flexible region for facilitating folding thereof, which is spaced laterally outwardly apart from corresponding one of the joints: and a buffer region of a predetermined width between the flexible region and the corresponding joint. The compression energy of the buffer region in its thickness direction is in a range of 0.4 to 1.0 (N·m/m 2 )·

Disclosed is a sanitary napkin having extensions, parts of which are to be folded back and fixed on an undergarment in use. The sanitary napkin includes: a liquid-permeable topsheet disposed on one side of the sanitary napkin to cover a central region thereof; a backsheet; an absorbent layer disposed therebetween; and leakage preventing portions disposed on laterally opposed side portions of the topsheet and extending in a longitudinal direction of the sanitary napkin. Joints between the respective leakage preventing portions and the topsheet are formed to extend in the longitudinal direction. The extensions are portions of the sanitary napkin extending laterally outwardly beyond the joints. Each extension includes a flexible region for facilitating folding thereof, which is spaced laterally outwardly apart from corresponding one of the joints and has a stiffness lower than that of a region between the flexible region and the corresponding joint.
摘要:
A sanitary absorbent article such as a sanitary napkin, or incontinence pad having a cover layer that is fluid permeable, an absorbent system and a liquid-impervious barrier layer under the absorbent system to prevent collected liquid to escape therefrom. The fluid-permeable cover layer is attached to the liquid-impervious barrier layer to form a flange seal enclosing the absorbent system. The flange seal includes two zones, namely a first zone and a second zone separated by a common boundary, each zone manifesting different mechanical properties. The first zone that resides closer to the outer edge of the flange seal is more resistant to shear stresses than the second zone residing near the inner edge of the flange seal. This arrangement reduces the likelihood of the flange seal being torn during use of the sanitary absorbent article.
摘要:
The present invention relates to a disposable absorbent article such as a sanitary napkin or a panty-liner, basically comprising an upper layer, a lower layer and an absorbent core of a design suitable to be used with tanga-type underwear, disposed between both layers; the core has a front section and a back section and wings or lateral projections preferably extending along the entire length of the absorbent core.
