DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention concerns a sole-shaped disposable hygienic insert with sweat-absorbing pad, of an article of footwear such as mules, half-mules or ballerinas or of an article of clothing such as ankle socks or socks of this type including a permeable film in contact with the foot, an absorbent layer and a film in contact with the shoe.
BACKGROUND OF THE INVENTION
Such an absorbent inner sole is already known from the document FR 87 09 708.
In addition, various makers offer inner linings or "inner soles" which are not well adapted to the problem of heating up of the feet as a result of excessive sweating, their aim being above all to obtain a warmer shoe, or height compensation between the shoe and the foot. These essentially flat inner soles made of natural products such as skins, leather, cork, textiles or synthetic products, are made of a single material or of combined materials.
The average life of these types of linings is equivalent to the life of the shoe for the most durable ones; comfort and hygiene are reduced even if some linings are washable. In addition, the materials used become either weak or more and more rigid, depending on their nature.
The principle drawbacks are as follows: shoe, as socks, stockings, or tights, due in particular to the accumulation of sweat, fungal infections,
OBJECTIVES AND SUMMARY OF THE INVENTION
The object of the invention is to remedy these drawbacks, and to this end concerns an insert of the type defined above, characterized in that: packed,
The insert makes it possible to eliminate sweat as uniformly as possible by drainage associated with frequent replacement (disposable insert), which provides a particularly hygienic lining. The shape of this insert corresponds principally to the sole of the foot, but it may extend onto the sides and the top, in the mule and ballerina versions. In the very economical versions, the insert is flat, in the form of a strip with two rounded ends.
The mule and ballerina versions may also be provided with a textile or a film covering the rest of the foot, the ankle and the calf, in order to provide an ankle sock and a sock, but also a half-mule version constituted only by the front of a mule.
According to other advantageous characteristics: hygienic pad. micro-funnels, or cut by small slits, single or combined into stars, produced without removal of material. insert, comprising pellets or reactive surfaces which gradually change colour, depending on the concentration of sweat. the pad or simply by one or both films, shaped and then glued or welded to one another completely or at various points, or by separate upper and vamp parts also joined by gluing or welding to the base insert, or it is provided with a textile or a film covering the rest of the foot, the ankle and the calf in order to provide an ankle sock and a sock. the foot. situated on the outer film in order to be applied, without spoiling, to the insole and/or to the sides of the shoe, or situated on the inner film of a mule or a ballerina, in the direction of the top and of certain lateral areas of the bare or sock-covered foot. continuous manufacture of an assembly formed of the outer sealing film, the hygienic pad, the inner film, itself optionally provided with another film, to form a sheet which is cut out to the shape of the insert to be manufactured, the cut-out portions being welded at the same time in order to provide the disposable insert.
