US Patent 7288081 Disposable wearing article

In a disposable wearing article, connector sheet strips for connecting front and rear waist regions of the article have proximal sections and flap-like sections. The proximal sections are fixed to the rear waist region on its inner surface along zones contiguous to transversely opposite side edges of the rear waist region. Flexural rigidity of the flap-like sections as measured in a transverse direction of the article is higher than that of the article as measured in regions lying immediately inside the respective zones which are, in turn, contiguous to the respective side edges, so that a direction in which the connector sheet strips extend can be easily reversed.
