  • Publication number: 20060100599
    Abstract: The present invention relates to packaged absorbent articles, which are disposable absorbent hygiene articles especially as incontinence care articles like baby-, adolescent- or adult-diapers or training pants, diapering inserts. Such articles are conventionally packaged in bulk quantities such as a household quantity (for example a weekly of fortnightly average consumption quantity of articles) or in institutional quantities of several time the household quantity. The present invention is based on the recognition that there is a need for individually packaged or very small quantity packaged articles. The improvement provided by the present invention is based on the recognition that the article configuration of bulk packaged articles is unsuitable for individually packaged or very small quantity packaged articles.
