Abstract
Disclosed are diapers, and particularly baby diapers, which are made and provided to the user of such products in a substantially flat condition and are formed into a three dimensional garment by the diaper user and maintained in this position by means of a closure system. The closure system consists of a tape type closure system with a designated zone on the diaper where the tape type closures are to be attached. Preferably the closure system comprises a mechanical interlocking system known as hook loop fastening system or as Velcro™ closure systems.
Claims10
A disposable diaper comprising a longitudinal center line defining a longitudinal direction and a transverse center line defining a transverse direction perpendicular to said longitudinal direction, said diaper having a front portion, said front portion being intended to be worn towards the belly of a wearer during use, and a rear portion being intended to be worn towards the back of a wearer during use, said transverse center line separating said front and said back portion, said diaper comprising an inside and an outside surface, said inside surface facing towards the wearer during use and said outside surface facing away from the wearer during use, said diaper having two longitudinal side edges, both extending from said front into said rear portion of said diaper, and two transverse ends, one in each of said front and said rear portion of said diaper,
- said diaper further comprising a closure system, said closure system comprising a landing zone having loop engagement elements and at least two tapes each comprising a mechanical hook fastener capable of engaging with said loop engagement elements,
- wherein said landing zone is provided on said outside surface of said front portion of said diaper, said landing zone has a longitudinal dimension and a transverse dimension, said landing zone has a central portion and a boundary portion, said central portion is optically highlighted versus said boundary portion, said central portion has a maximum longitudinal dimension which is smaller than said longitudinal dimension of said landing zone, said boundary portion has a dimension in longitudinal direction making up the difference between said longitudinal dimension of said central portion and said longitudinal dimension of said landing zone,
- wherein each of said tapes is provided in said back portion of said diaper and extends beyond said longitudinal side edge of said diaper during use, each of said tapes is substantially non-elastic and comprises said mechanical hook fastener on said portion of said tape which extends beyond said longitudinal side edge during use, said mechanical hook fastener has a longitudinal dimension, said portion of said tape which extends beyond said longitudinal side edge of said diaper during use having a longitudinal outer tape edge, a portion of said tape between said longitudinal outer tape edge and said mechanical hook fastener provides a finger tab for manipulating said tape from a disposition in which said tape is delivered for usage into a position during usage of said diaper,
- wherein said hook fastener longitudinal dimension is from 60% to 125% of said maximum longitudinal dimension of said central portion of said landing zone,
- wherein said longitudinal dimension of said mechanical hook fastener is not larger than said longitudinal dimension of said landing zone, and
- wherein said longitudinal outer tape edge forms a wavy line for improving the possibility to grab said finger tab.
