Abstract: A support unit for supporting a drain tap in a flexible bag located in a bag-in-box (BIB) liquid dispenser includes a substantially planar plate with a least one surface adapted to abut the outer surface of the box. The support unit has a slit to receive the drain tap when lead through the wall of the box and form a supporting collar around the drain tap where the plate area next to the slit tapers towards the opening of the slit, forming two tapering areas on each side of the slit. The support unit may further include an area that is convex.

Abstract: A method for manufacturing an accordion filter insert in which an accordion filter pack is introduced into a mold and a space remaining thereafter in the mold is filled with a liquefied polymer material so as to form a frame surrounding the accordion filter pack. At least one peripheral elastically deformable sealing lip, consisting of the material of the frame, is produced together with the frame and is consolidated concurrently therewith.

Abstract: A filter arrangement made up of an accordion fold pack which is sealingly arranged in a housing. The housing is deep drawn in one piece from a polymeric material sheet. A limit stop is punched out of the base of the housing. A seal surrounds the accordion fold pack and seals against the housing.

Abstract: A method for manufacturing a filter cartridge that has a filter medium, which, on the circumferential side, is surrounded with clearance by a gasket-seal. The method provides for a frame to be arranged in the gap formed by the clearance, and sealingly bonded to the edges of the filter medium and the gasket-seal.

Abstract: An accordion filter insert has a frame formed about the filter material. The frame has an elastically deformable sealing lip on the periphery of the frame. The elastically deformable sealing lip is formed of the same material as the frame itself. The sealing lip and frame are formed as a unitary piece.

Abstract: A cartridge filter has a filter element and a frame formed of plates. The plates are installable around the filter element and are interconnectable in the area of the sides of the plates. The plates have plug-in connection members which interact with corresponding plug-in connection members of adjacent plates to thereby affix the plates to one another.

Abstract: A filter cartridge has a frame made of tough material, which sealingly surrounds an accordion fold pack on its circumferential side. The frame is made of assemblable, plate-shaped frame elements and has, on the circumferential side along the lower and/or upper edge of the frame, a tongue, the tongue being insertable in a latticed holder having a U-shaped profile. A viscous joining compound is used to affix the tongue in place. The tongue is formed by strip-shaped tongue elements, each tongue element being joined to a frame element, wherein the adjacent ends of the tongue elements are sealingly fastened to each other by connecting corner pieces.

Abstract: A filter insert. The filter insert includes an accordion fold pack that is made of a filter material and is joined to a filter frame. The material of the filter frame is injected in a flowable state into the folds of the accordion fold pack which are open in the on-coming flow direction of the medium to be filtered. The material is subsequently hardened during automatic claw fixation with the fold walls. The entire peripheral edge of the accordion fold pack sealingly overlaps the outer boundary surfaces of the filter frame, and is designed as a sealing device.
