摘要： A filter assembly for use with a bottle having a circular cross-section neck or open end includes a fine filtration media having a mean pore size of about 1-3 microns and capable of removing contaminants of 3-4 micron size and larger, and an inner filtration media disposed radially inward of the fine filtration media. The inner filtration media includes activated carbon, preferably a porous activated carbon/plastic matrix having a porosity of between about 10-150 microns. The outer housing contains the fine filtration media and the inner filtration media, and is dimensioned to pass through the neck or open end of the bottle. The fine filtration media preferably comprises sheets on opposite faces of a microfiber filter media formed of glass microfibers of varying cross-sectional diameters, with the fine filtration media in a pleated or accordion configuration. A filter assembly may also be provided having a spring pressed straw. The filter assembly may also include a generally tubular plastic housing with a number of ribs each having an inner surface and an outer surface at least 50% larger than the inner surface. The filter element may also be provided comprising a porous rigid matrix of at least 35% activated carbon, styrene, and metal removing polymer bound to the styrene. Also the filter assembly may have a filter element housing extending upwardly from and operatively connected to a cap and having a maximum cross-sectional area at least 20% larger than the cap top area, for example in the form of a disc or a sphere. The filter may be formed by mating hemispherical portions, and the housing may have a novelty configuration.
摘要翻译：用于具有圆形横截面颈部或开口端的瓶子的过滤器组件包括平均孔径为约1-3微米并且能够去除3-4微米尺寸和更大的污染物的精细过滤介质，以及内部过滤介质径向向内设置在精细过滤介质上。内部过滤介质包括活性炭，优选孔隙率在约10-150微米之间的多孔活性炭/塑料基质。外壳包含精细的过滤介质和内部过滤介质，并且其尺寸适于通过瓶的颈部或开口端。精细过滤介质优选地包括由具有不同横截面直径的玻璃微纤维形成的微纤维过滤介质的相对表面上的片材，其中精细过滤介质是打褶或手风琴构型。还可以提供具有弹簧压缩的吸管的过滤器组件。过滤器组件还可以包括具有多个肋的大体上管状的塑料外壳，每个肋具有内表面和比内表面至少大50％的外表面。还可以提供过滤元件，其包含至少35％活性炭，苯乙烯和结合到苯乙烯的金属去除聚合物的多孔刚性基质。而且，过滤器组件也可以具有从帽盖向上延伸并且可操作地连接到盖子的过滤器元件壳体，并且具有比顶盖区域大至少20％的最大横截面面积，例如以盘或球体的形式。过滤器可以通过配合半球形部分形成，并且壳体可以具有新颖的构造。
