CA 2564894

A pad (1) of the optionally flexible, disc-shaped/flat type filled with a product to be extracted such as ground coffee and/or a product to be dissolved such as a creamer, provided with an optionally flexible bottom sheet (4) manufactured from, for instance, filtering paper and an optionally flexible top sheet (6) manufactured from, for instance, filtering paper, the top sheet and the bottom sheet being interconnected at their longitudinal edges so that a covering with a circumferential sealing seam (8) is formed, with the product situated between the top sheet and the bottom sheet, the bottom sheet and the top sheet each forming a filter which is at least virtually impermeable to the product and which is at least permeable to water, while an area (10) of the covering is designed to be at least virtually impermeable to water, the area comprising, preferably, at least one annular sub-area (12) covering at least a part of the sealing seam, and that the area extends outside the sealing seam at predetermined positions.

L'invention concerne une dosette plate, discoïde et éventuellement souple, remplie d'un produit destiné à être extrait, tel que du café moulu et/ou un produit à dissoudre, tel que de la crème, comportant une feuille inférieure éventuellement souple fabriquée, par exemple, à partir de papier filtre, et éventuellement une feuille supérieure fabriquée, par exemple, à partir de papier-filtre, lesdites feuilles supérieure et inférieure étant reliées entre elles au niveau de leur bord longitudinal, de sorte qu'une enveloppe à soudure circonférentielle soit formée, le produit étant placé entre les feuilles supérieure et inférieure. Ces feuilles forment chacune un filtre au moins pratiquement imperméable au produit et au moins perméable à l'eau. Une zone de l'enveloppe est conçue pour être au moins pratiquement imperméable à l'eau, et comprend de préférence au moins une enveloppe de sous-zone annulaire, au moins une partie de la soudure, et s'étend vers l'extérieur de la soudure en des points déterminés.
