Definitions

• This invention relates to an absorbent article. It is particularly concerned with an absorbent article, for example in the form of a sanitary pad, which can be used by women suffering from light and moderate incontinence.
• an absorbent article for example in the form of a sanitary pad, which can be used by women suffering from light and moderate incontinence.
• the invention will be so described below.
• the invention is of more general applicability in relation to the abso ⁇ tion of body fluids, either urine or menstrua.
• an elongate absorbent article which comprises a fluid-permeable topsheet, a core for providing fluid-storage, a fluid- receiving layer located between the topsheet and the core for transferring to the core fluid which passes through the topsheet, and elastication means located between the core and the fluid-receiving layer, the elastication means being in tension when the article is in a generally flat condition.
• the fluid-receiving layer is referred to below as a secondary topsheet.
• Figure 1 is a perspective view of an embodiment ofthe invention
• Figure 2 is a longitudinal section through the embodiment of Figure 1, taken along the longitudinal centre line thereof,
• Figure 3 is a transverse section through the embodiment of Figure 1, taken on the transverse centre line thereof, and Figure 4 is a view similar to Figure 3 but showing a modified embodiment.
• the embodiment shown in Figures 1 to 3 is an absorbent sanitary pad for use by a woman suffering from light incontinence. It comprises a fluid-permeable topsheet 1, a fluid-impermeable backsheet 2 which is sealed thereto, by a seal 3 at the periphery ofthe article, for example by heat sealing or adhesive.
• the article further comprises an absorbent core 4, for example one which contains an absorbent gelling material (AGM), and a secondary topsheet 5 which serves to receive fluid and transfer it to the core.
• AGM absorbent gelling material
• topsheet, backsheet and absorbent core may be those which are conventionally used for absorbent sanitary products.
• the article further comprises an elastication system which serves to cause the article to curve in a way which enables it to conform closely to the user's body and at least substantially prevent, or reduce, the risk of urine escaping past it.
• this elastication system comprises an elastic thread 6 which runs along at least a major portion ofthe length ofthe article, preferably substantially the whole length ofthe article, beneath the secondary topsheet 5, and is attached at its ends, or along its whole length, or at selected points along its length, to the secondary topsheet and/or to the core. As can be seen, this causes the pad to assume a configuration which is upwardly concave as seen in longitudinal section (Figure 2), and upwardly convex as seen in transverse section (Figure 3).
• the pad is thus resiliently raised towards the body of the user and held in close contact with it, so providing a better fit and a better ability to acquire even the lightest release of urine.
• the core is relatively stiff, and stays substantially flat as view in transverse section, thus enabling it to maintain good contact with the user's panty.
• Figure 4 shows a modified embodiment which comprises in addition an elastic thread 7 which runs transversely above the core 2, and below the secondary topsheet 5 with its longitudinal elastic thread 6.
• the transverse elastic thread 7 is shown fixed to the secondary topsheet 5, though if it were slightly longer it could alternatively, or additionally, be fixed to the primary topsheet 1. In any event, it is preferably fixed only at its ends. By pulling the sides ofthe secondary topsheet and/or primary topsheet inwards, the transverse elastic thread assists in giving the article, as seen in transverse section, the desired upwardly convex shape.
