Embodiment Construction

[0010] The present invention relates to a method of applying a fastening device to an absorbent product, and to an absorbent product comprising the fastening device, and to the use of expandable inks in fastening devices for absorbent products. When ready for use, the fastening means includes an adhesive area and a raised non-adhesive area. The raised non-adhesive area acts as a distance that protects the adhesive from inadvertent contact and prevents the adhesive area from contacting any surface unless it is pressed against the surface. The fastening device thus does not need to be protected by a release sheet during manufacture, packaging or storage. When the absorbent product is attached to a surface, such as a textile surface, the raised areas act as spacers and initially prevent contact between the adhesive and the surface. The absorbent product is held in place due to friction between the raised areas and said surface. When the user applies pressure on the absorbent pr...

Abstract

A method of applying a fastening means to a back sheet of an absorbent product, said back sheet facing away from the user during use, and being opposite to a body facing side of the absorbent product, which method comprises the steps of applying an adhesive layer on the back sheet of the absorbent product, and applying an expandable ink wherein 5-95% of the back sheet is covered by the expandable ink; and an absorbent product comprising a body facing side, a back sheet facing away from the user during use, and being opposite to the body facing side of the absorbent product, and a fastening means applied on the garment facing side, said fastening means comprising an adhesive layer and an expandable ink.

Description

technical field [0001] The present invention relates to a method of applying fastening means to the backsheet of an absorbent product, to an absorbent product comprising the fastening means, and to an expandable ink in combination with an adhesive layer as a fastening means. The purpose of the fixed device. Background technique [0002] Absorbent products, such as pantiliners, sanitary napkins, and incontinence pads are often held in place by pressure sensitive adhesives, such as double-sided tape or hot melt adhesives applied on the garment-facing side of the product. form. The adhesive holds the absorbent product in place by adhering it to the crotch of the user's underwear. The pressure sensitive adhesive is covered with a release paper which prevents the adhesive from inadvertently sticking during manufacturing, packaging and storage. Before applying the product to underwear, the user must remove the release liner, thus creating waste. US 6004308A discloses an adhesi...
