Claims45
A disposable diaper, comprising:
- an absorbent pad, a fluid impervious backing sheet defining a back surface of the diaper, a front surface, a plurality of longitudinally extending folds defining a box-pleat configuration of the diaper, a pleated end flap of the box-pleat diaper adjacent one end of the diaper, said pleated flap being folded over the front surface of the diaper, and means for retaining at least a portion of the flap against the underlying front surface of the box-pleat diaper.
A disposable diaper, comprising:
- an absorbent pad, a fluid impervious backing sheet, a pair of side edges, a pair of end edges connecting the side edges, with said backing sheet extending to at least one end edge of the diaper, a front surface, a box-pleat fold of the diaper defining a longitudinally extending central panel, a pair of first pleat panels extending from and overlying the central panel, and a pair of second pleat panels extending from and overlying the first pleat panels, and end section of the diaper including flap means adjacent said one end edge of the diaper having its front surface folded against the front surface of an inner adjacent portion of the diaper relative said one end edge, and means for securing a lateral region of the flap means to the front surface of said adjacent portion of the diaper, with a second lateral region of the end section being free of attachment from the diaper.
A disposable diaper, comprising:
- an absorbent pad having a pair of end edges, a backing sheet having a portion extending past at least one end edge of said absorbent pad, a front surface, a plurality of folds defining a pleated configuration of the diaper, an end section of the extending portion of said backing sheet, said end section having at least a portion of its front surface folded against the front surface of the diaper adjacent the end section after formation of the pleat with said end section overlying at least a portion of the pleat, and means for retaining a portion of the end section against the front surface of the diaper underlying the end section.
A method of making a disposable diaper, comprising the steps of:
- folding a flat diaper having a fluid impervious backing sheet into a box-pleat configuration;
- folding an end section of the box-pleat diaper including a portion of the backing sheet over the top of the diaper with a front surface of the end section facing the front surface of the diaper adjacent the end section;
- and
