Patent ID: 7470264

Claim:
A disposable wearing article having longitudinal and transverse directions, said article comprising: a liquid-impervious chassis comprising: an inner surface, a front waist region, a rear waist region, and a crotch region extending in the longitudinal direction between the front and rear waist regions, front and rear ends respectively extending across said front and rear waist regions in said transverse direction, and opposite lateral sections extending in said longitudinal direction between said front and rear ends; a body fluid absorbent first panel having a front portion, a rear portion and opposite side edges, and being laid on the inner surface of said chassis so as to extend over said rear waist region and said crotch region of said chassis; and a body fluid absorbent second panel having a proximal portion, a distal portion and opposite side edges, and being laid on the inner surface of said chassis so as to extend over said front waist region and said crotch region of said chassis; wherein said first panel is fixed at least at said front and rear portions to said chassis while said second panel being fixed at least at said proximal portion to said front waist region of said chassis; said distal portion of the second panel extends over said crotch region of said chassis; said opposite side edges of said first and second panels extend along the opposite lateral sections of said chassis; said distal portion of said second panel is bent, along a bending zone contiguous to said proximal portion, upward at a predetermined angle with respect to said chassis so as to define an upward convex shape and to form between said chassis and said upwardly bent distal portion a pocket which opens toward said rear waist region; said front end of said first panel extends into said pocket and terminates within said pocket at a location rearwardly spaced in the longitudinal direction from said bending zone of said second panel; and said pocket is provided with a spacer extending in said transverse direction, said spacer having transversely opposite ends joined to at least one of the transversely opposite lateral sections of said chassis and transversely opposite lateral portions of the distal portion of said second panel, and an intermediate section defined between said transversely opposite ends, wherein the transversely opposite lateral sections of said distal portion are drawn by said spacer inward as viewed in said transverse direction of said chassis to keep the distal portion of the second panel in said upward convex shape and spaced upwardly from the intermediate section of the spacer.
