ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to absorbent garments, especially incontinence protectors, according to the preamble to the appended claim
1
.
BACKGROUND
An absorbent garment of the above mentioned type is described in the Swedish Patent Application 9301631-9 and shows fixed tapes of hook material for hook and loop joints on the absorption unit, also known as a chassis. These are intended to cooperate with the outside of the belt. For this purpose the outside of the belt is made as a unit from a complementary hook and loop material suitable for cooperation with the hook material—a loop material. The belt is made as a multilayer laminate.
In order for the fastening means to be able to hold up a large, fluid-drenched absorption unit by the belt, a hook and loop material with a relatively high force transmitting ability is required. Such materials are expensive, wherefore the belt becomes expensive. This is unfavourable, especially if the belt is intended for single use or is fastened to a garment of single use-type.
A similar fastening between an absorption unit and a belt is shown in EP-A-0 409 307, where the belt is intended to be able to be used a number of times.
Additionally, GB 2 257 895 describes a hook and loop fastening arrangement in another type of product, viz. an hourglass-shaped diaper or incontinence protector without a belt. In each end part of the rear waistband is fastened a projecting tape, which supports a hook and loop fastening means. This has two hook and loop tapes which grip each other and an outwardly facing layer of glue which during the first use of the diaper is fastened on the front waistband. The joint can thereafter be opened and closed by the hook and loop tapes being pulled apart and pressed together again.
A motive for the invention is the task of providing an absorbent garment of the type mentioned in the introduction, especially for single use, which is cheaper than known such garments. It should, however, still be possible to comfortably adapt the garment to the shape of the body of the user by the selection of different connecting positions between the absorption unit and the belt.
SUMMARY OF THE INVENTION
According to the invention this task is fulfilled through the garment having the characteristics mentioned below.
As the belt material itself does not need to interact with the first hook and loop material, which appropriately is a hook material, it can be made of a cheap and pliable material, e.g. a thin nonwoven textile material, nonwoven, a plastic film coated or laminated with an outer material which is kind to the skin, or even a purely plastic film. The exposed glue layer on the fastening means can be fastened in arbitrarily desired places on the belt the first time the garment is used, whereby an optimal fitting of the garment to the user is achieved. The absorption unit can thereafter be detached and refastened to the belt through the hook and loop joints being opened and then pushed together again. If the two pieces of complementary hook and loop material then are again positioned directly in front of each other, the earlier made fitting of the garment is again achieved but a certain adjustment is also possible.
An advantageous design for packing without projecting tapes or ends of bands is obtained by the protective layer being fastened to the inner casing layer on the end part of the front short side. The fastening means in the unused condition then is fastened to the front short side and can be removed and folded out when the short side is to be fastened to the belt for the first time. As the protective layer is attached to the absorption unit, the user does not have to take care of loose protective layer pieces when the garment is to be put on.
Further advantages and characteristics of the invention are evident from the independent claims and from the following description of embodiments with reference to the accompanying figures.
