Problems solved by technology

[0008] Although electronic detection devices that indicate the state of absorbents have significant advantages over visual detection devices, they still suffer from the disadvantages of being expensive, rigid, bulky, and difficult to incorporate into absorbents during manufacture
Also, many traditional (silicon-based) electronic components are not easy to handle or degrade (for example, batteries and PCBs (printed circuit boards))

Embodiment Construction

[0022] absorbent

[0023] The present invention relates to absorbent articles such as diapers, cover diapers, belt diapers or incontinence pads, indicated generally at 10 in FIG. 1 . The absorbent article comprises a liquid permeable topsheet 12, a liquid impermeable backsheet 14, and an absorbent core 16 located therebetween.

[0024] The liquid-permeable topsheet 12 is optionally composed of a nonwoven material such as continuous fiber spunbond, meltblown, bonded carded web, or apertured plastic film. Laminations of different types may also optionally be used, for example, laminations of non-woven materials and plastic films. Materials suitable for the liquid-permeable topsheet 12 should be soft and non-irritating to the skin. Furthermore, the topsheet 12 may be different in different parts of the absorbent article 10 .

[0025] The liquid-impermeable backsheet 14 may consist of a plastic film, a non-woven material treated with a liquid-impermeable material, or a hydropho...

Abstract

The present invention concerns an absorbent article (10) comprising at least one wetness detecting means (18). This at least one wetness detecting means (18) comprises an electrical circuit (20), which is integrally formed into said article (10). The at least one electrical circuit (20) is fabricated from an electrically active material (22) which has been printed onto one or more components of the absorbent article (10).

Description

technical field [0001] The present invention relates to absorbent articles comprising wetness detection means. Background technique [0002] Absorbents containing different types of detection means are known which help to alert the user or caregiver of changes in the absorbent (eg soiling events). Such detection means allow the user or caregiver to easily determine whether the absorbent needs to be replaced without the need for careful inspection or removal of the absorbent. [0003] Well known detection devices that can be incorporated into absorbents are chemicals that change their form or properties upon contact with liquid. For example, an indication that the absorber is soiled may come from a color change or appearance or disappearance of elements on the absorber. Such techniques are known, for example, from US 5389093, WO 04 / 028403 and WO 05 / 030084. Such detection devices are useful in certain situations, but not so useful in facilities like childcare centers, aged ...
