Abstract
Symmetrical ends of a diaper are fastened by the use of hook and pile fasteners which are mounted on wings that extend laterally from the main diaper body. The hook sections of the fastener are substantially longer than the pile sections and face outwardly of the diaper so as not to irritate an infant's skin yet allow a large degree of adjustability. Elastic strips are sewn to the main body in the vicinity of the leg openings to make the diaper hug the legs of the infant. The diaper is composed of a plurality of layers of material which channel moisture to a central layer which is not easily contacted either from the inside or outside of the diaper. Quilt stitches can also be included to dissipate moisture along the entire length of the diaper.
Claims12
A reusable diaper for children comprising:
- a main body having inwardly and outwardly facing surfaces, a first longitudinal end, a second longitudinal end, a first side edge and a second side edge;
- a first pair of oppositely directed laterally extending wings formed on said first end;
- a second pair of oppositely directed laterally extending wings formed on said second end and adapted to overlap said first pair of wings;
- hook and pile fastener means connected to said first and second pairs of wings and comprising a hook section and a pile section for maintaining said wings in overlapped disposition to form said diaper to the torso of an infant;
- wherein said hook section is disposed on said outwardly facing surface of said first pair of wings and said pile section is disposed on said inwardly facing surface of said second pair of wings;
- and
- elastic stretch means attached longitudinally of said body for gathering portions of said body about the legs of an infant;
- wherein said hook section is substantially greater in length than said pile section, and
- wherein said elastic stretch means comprises two elastic strips attached to the outer surface of said main body in a position substantially parallel to and spaced laterally from said first and second side edges for providing padding on both sides of each elastic strip.
