Abstract: The invention relates to a filter system (10) including a filter element (14) for filtering a fluid within a cylindrical case (12). The filter element is an absorbent tissue paper material in the form of a sheet compactly wound to form inner winding turns therein and to form a tubular cylinder inside the case (12) in a manner to partition a radially outside part (26) from a radially inside part (30). The axial ends of the filter element are capped by the closed ends (18, 20) of the case. The inner winding turns exhibit a contour which prevents the inner winding turns from unraveling inward. In operation, the fluid moves across the filter element (14) in a generally centripetal direction. The filter element (14) is characterized in that it is devoid of a central core.

Abstract: The invention proposes a dispenser of paper, or other equivalent product, including a housing storing the product in the form of folded sheets to be dispensed through a dispensing opening. The paper is contained in a detachable cartridge compatible with the paper dimensions and assembled to the dispenser inside the housing. The cartridge includes an end wall situated opposite an opening of the housing wherein is located a dispensing slot of which the shape matches the paper sheets to be dispensed. The cartridge includes walls which guide the stack of folded sheets.

Abstract: The invention proposes a dispenser for a web wound into a coreless roll, the roll (11) being mounted on an irrotational, substantially cylindrical support spindle (14), the web in this dispenser being dispensed by rotationally unwinding the roll (11) around the axis (A1) of the support spindle (14), characterized in that the support spindle (14) includes means (46, 48, 50, 52) axially locking the roll (11) and in that the spindle (14) bears means (36, 50, 52) for decelerating the roll (11) being unwound.
