BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a pant diaper or a sanitary panty which includes a front part, a rear part and an intermediate crotch part and an absorbent body enclosed between an inner and an outer casing sheet, wherein the front part is detachably joined to the rear part by means of a first fastening.
BACKGROUND OF THE INVENTION
So-called all-in-one diapers are being replaced to an ever greater extent with pant diapers, sometimes called training pants, for slightly older diaper-wearing children. Pant diapers have a number of good features. They fit well on the wearer, are easy to put on and take off with the child in a standing position, sit firmly in place after having been put on to a child, and conform to the anatomy of the child as the child moves, in a comfortable fashion. Pant diapers also resemble conventional underpants and it is easy to understand how the pant diaper shall be used, thereby in many instances enabling somewhat older diaper-wearing children to perform themselves the simple operations required when putting on the pant diaper. Pant diapers, however, also have certain drawbacks. They are difficult to change with the user lying on his/her back and when changing the pant diaper it is necessary to remove completely any article of clothing that is worn on top of the diaper. Neither can a used pant diaper be rolled-up and sealed in a bag in the same way that an all-in-one diaper can. In addition, a soiled pant diaper that contains feces is liable to soil the wearer when removing the pant diaper.
GB-A-2 267 024 teaches a pant diaper of the aforesaid kind which is intended to eliminate these drawbacks. The first releasable fastening is comprised of weakening lines in the front part, close to respective side edges thereof, and the refastenable fastening is comprised of fasteners of the hook and loop type attached to flaps which extend from respective side-edge connections between the front and rear part, slightly inwards over the front part. Many hand maneuvers are required to open such a pant diaper, while opening of the pant diaper is made difficult by the fact that the weakening lines are relatively inaccessible. Moreover, the join formed by the weakening lines complicates manufacture of the pant diaper.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a pant diaper which, similar to the aforesaid known pant diaper, eliminates the drawbacks of conventional pant diapers, and which can be opened easily with a few hand movements and which can be readily manufactured.
This object is achieved in accordance with the invention with a pant diaper or sanitary panty of the kind defined in the introduction which is characterized in that a piece of flexible material extends over said front part and is joined thereto over a large part of its surface by a first releasable fastening which extends on both sides of a centrally located region of the piece of material, from the side edges of the central region to respective side edges of the front part, and in that said piece of material is also joined to the rear part. Because the first fastening extends over a large surface, it is possible to dimension this fastening with a high degree of safety so that the forces that are generated when the pant diaper is in use, particularly when putting-on the pant diaper, will be taken-up by the first fastening with a good margin, while, at the same time, enabling the fastening to be readily released by successively removing the piece of flexible material from said front part.
In one preferred embodiment of the invention said piece of material is connected refastenably with the front part by means of a second fastening and the first fastening means is destroyed when releasing the fastening. The first fastening may conveniently consist of a sparsely configured weld or glue pattern, and the piece of material is elastic and mounted in a stretched state, so as to function as waist elastic. Provided in the centre region of said piece of material is a means for dividing said
