An apparatus pertains to a product preparation featuring a permeable body comprising an extraction chamber(s), along with a flexible, free-motion mechanism structure appropriately coupled to the body. The apparatus is equipped with a sealing mechanism at an opening, allowing for the insertion of a predetermined portion of ingredients. In some embodiments, to enhance filtration, a sleeve filter may be inserted within the container. When the container is submerged in a vessel to a level suitable for extracting a beverage, it securely affixes to the inner wall of the vessel through the flexible structure. The depth within a vessel is adjustable to control the product quality.
