DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to an absorbent article in the form of a pants-type diaper or a sanitary panty which comprises an elongated absorbent body enclosed between two casing sheets which at opposing front and rear end parts of the absorbent body have side parts which extend laterally beyond the absorbent body on both sides thereof.
So-called all-in-one diapers are being replaced to an ever greater extent with pants-type diapers, or so-called trainers, for slightly older diaper-wearing children. Pants-type diapers have a number of good features. They fit well on the wearer, they are easy to put on and take off with the child in a standing position, they sit firmly in place after having been put onto a child, and conform to the anatomy of the child as the child moves, in a comfortable fashion. Moreover, pants-type diapers resemble conventional underpants and it is easy to understand how they shall be used, thereby in many instances enabling somewhat older diaper-wearing children to perform themselves the simple operations required in putting on the diaper. However, pants-type diapers, or trainers, also have certain drawbacks. They are difficult to change while the user is lying on his/her back and, when changing the diaper, require any garment that is worn on top of the diaper to be removed completely. Neither can a used pants-type diaper be rolled-up and sealed in the same manner as an all-in-one diaper. In addition, a dirty pant diaper which contains feces is liable to soil the wearer when removing the diaper.
OBJECTS AND SUMMARY
An object of the present invention is to eliminate the aforesaid drawbacks.
According to the present invention, this object is achieved in that an absorbent article in the form of a pants-type diaper or a sanitary panty, wherein mutually opposing front and rear side parts are joined together through the medium of a fastener element which is joined to one of the mutually opposing side parts by means of a first, strong join or fastening and can be released from and refastened to the other side part by means of a second join or fastening which is weaker than the first join, is characterized in that the second join includes a first fastener means which is destroyed when the second join is opened for the first time, and a second refastenable fastener means which cannot be opened for a first time without destroying the first fastening.
According to a preferred embodiment of the invention, the second join is stronger in a non-released state than when resealed after being released for the first time . The first fastener means is comprised of a weld join or a glue join and the second fastener means is comprised of a mechanical fastener type and the mechanical fastener is the fastening type. The fastener element is preferably comprised of the male part of a ribbon-like self-fastening fastener, i.e. that part of such a fastener which includes a large number of hooks projecting from one surface thereof, and the female part of the self-fastening fastener is comprised of a nonwoven material which forms a casing sheet of the article at the same time.
