Abstract: The invention relates to a device (1) for filtering a liquid under pressure, provided with a containment enclosure (4) for a filter (8), containing a volume of water which varies independently of the volume of water contained in the rest of the device. Said enclosure, also called a “cage”, is suitable for allowing the containment therein of a filter (8), such that said filter is fully submerged for a suitable amount of time for the filtration cycle.

Abstract: A device for filtering liquid, including a first reservoir for collecting filtered liquid, a second reservoir for liquid to be filtered, the second reservoir contained at least partially in the first reservoir, the walls of said second reservoir having at least a filtering opening allowing transfer of liquid between the first and second reservoirs, an injection opening having a filter blocking the filtering opening, and a flexible pressurization device to inject air into the second reservoir via the injection opening. The pressurization device is located completely outside the second reservoir, and has a volume that is variable between two positions: a deployed position, in which the volume of the pressurization device is maximal, and a folded position, in which the volume of the pressurization device is minimal.

Abstract: Waste collecting device including a base (10), an intermediate body (2) having a disk (30) for carrying three bags and having three openings for the passage of waste into the bags, a first cylinder or rod (34) arranged to slide along a second cylinder or rod (35) mounted on the base (10) so as to set the height of the intermediate body, and a cover (3) made of upper and lower elements (50,70), having a circular shape and pivotable around a horizontal axis. Both upper and lower elements include a half jaw which cooperate to crush and reduce the volume of waste items. Upper element (70) has an opening for the passage of glass bottles. Lower element (50) has a set of openings (51, 52, 53, 54, 55) arranged for the passage of waste items into a determined number of compartments and into the three bags.

Abstract: Filtration device for a closed container having a lower element and an upper element provided with an evacuation opening, the upper element adapted to be fixed in a sealed manner on the lower element; an internal filtration device including a reservoir provided with an opening in its upper portion allowing for its content to flow when the container is tilted toward the left or right; a filter, a filter support adapted to receive in a sealed manner the upper portion of the filter and the reservoir, a structural element cooperating with the filter support to define an intermediary volume adapted to receive the liquid after it has flowed through the opening, the structural element including a channel for the liquid to flow upward; the internal filtration device being arranged inside the container so as to enable collection of filtered liquid after passage through the filter.
