摘要： A disposable vacuum assisted filter funnel for filtering fluids into bottles. The bottle top filter forms a vacuum dependent seal with the mouth of the bottle. When fluid is introduced into the bottle top filter, the evacuated bottle draws the fluid through the filter into the bottle. The bottle top filter lacks a vacuum plenum between the vacuum source and the bottle. The bottle top filter may be manufactured from one molded piece.

摘要： A disposable filtration unit and method of manufacturing the same, the unit (10) comprising:
a) an upright, generally cylindrical wall (12) having an open top (24) and a closed bottom (26);
b) a shoulder (28) which extends radially inwardly from the internal surface of the cylindrical wall (12) intermediate the top (24) and bottom (26) thereof, which divides the internal volume, as defined by the cylindrical wall (12), into an upper reservoir (18) for receiving the liquid to be filtered and a lower receptacle (20) for receiving the filtrate, and which defines a first opening (32- in Figure 2) therethrough providing communication between the reservoir (18) and receptacle (20);
c) a perforated support plate (42,44) on the shoulder (28) and sealed about its periphery to the internal surface of the cylindrical wall (12);
d) a collar (46) formed integral with and depending from the support plate (42, 44) and extending through the first opening (32) and into the receptacle (20); and
e) a sheet-like filter medium (56) on the support plate (42, 44) with the periphery of the filter medium (56) being fixed to the support plate (42, 44),
wherein the shoulder (28) is formed integral, and being moulded together, with the wall (12), so as to form a unitary structure. The unit (10) may be provided with a pouring spout (22) which is formed integral with the cylindrical wall (12) and opens into the lower receptacle (20), this pouring spout (22) including a breathing tube (38) which communicates with the receptacle (20) at a point remote from the spout (22) and adjacent shoulder (28).-

摘要： A single use disposable filter unit is provided comprised of only two parts joined together, and with those parts configured to support the filter membrane without any additional parts. In addition, the arrangement herein provides for the joining of the two parts of the unit together simultaneously with the sealed annular seating of the periphery of the filter membrane with the filter unit body. Moreover, a decanting spout is incorporated into the unit without the need for a separate air vent.

摘要： A permanent, reuseable liquid filter comprises a thin flexible filter material (A) and a support skeleton (B) secured to the outside surface thereof. The skeleton includes a centrally disposed support rim (20) and a plurality of support rib sets (22) spaced around and extending outwardly from the support rim. Each rib set comprises a plurality of separate elongated ribs (24, 26, 28) extending from adjacent the support rim toward the filter material outer edge (14) with the ribs of each set being connected together by a first connecting web (34). A second connecting web (36) may be advantageously used to connect each support rib set to the support rim. The filter, when not in use, is normally in a generally flat condition as shown and automatically assumes the general shape of a filter basket or other support structure (not shown) upon installation thereinto. The support rim then generally defines a filter bottom area with the ribs (24, 26, 28) urging the remainder of the filter material (A) towards engagement with the filter basket or support structure side wall area. Any necessary filter material folds, pleats or flutes required to accommodate folding from the generally flat condition are formed between adjacent support rib sets (22) and extend generally coextensively therewith.
