Abstract: The invention concerns the manufacture of personal care articles consisting of compresses having a cooling effect by swelling with water which are presented individually in vacuum packaging. According to the invention, successive doses of powder comprising absorbent particles are placed in grooves formed by elastic deformation in a lower sheet made of water-permeable textile material, which is continuously unwound, and covered with an upper sheet, which is continuously unwound at the same time as the lower sheet. The lower sheet is then heat-welded in the intervals between adjacent grooves thus isolating the grooves from each other. Successive compartments each containing a dose of the powder are then enclosed in each groove by heat-welding the sheets along transverse weld lines across the width of the moving sheet assembly.

Abstract: The invention relates to a compress with a cooling effect, based on particles (6) of a polymer that has a high water absorption capacity, which comes enclosed with a reserve of water to activate it in an item (2) which comprises, inside a watertight outer sachet (3), on the one hand an inner pouch (4) filled with water and sealed in a watertight manner by a wall comprising a frangible region (10) and, on the other hand, the compress (1) produced in the form of a wrapper (5) at least partially permeable to water and containing the polymer particles (6) in the dry state. The sachet (3) is made of a material of a nature able to keep the pouch (4) and the compress (1) sterile.
