Patent number: 4765499Abstract: A venting closure (10) for containers (12) having a pour opening (14) defined by a circumferential rim (16) includes a top wall (20) having inner (22) and outer (24) surfaces. A side skirt (26) extends from the top wall (20) about the inner surface (22). A liner (28) is mounted adjacent the inner surface (22) for perfecting a seal between the top wall (20) and the circumferential rim (16) when the closure (10) is secured upon the rim (16) and over the opening (14). The liner (28) includes a gas impermeable non-hydrophobic portion (30) at least about the periphery of the liner (28) and an integral gas permeable hydrophobic portion (32) offset therefrom.Type: GrantFiled: December 29, 1987Date of Patent: August 23, 1988Inventors: Charles von Reis, Karlis Vizulis

Patent number: 4561868Abstract: A canister filter assembly (10) for use in a vacuum line for trapping particulates and liquids from fluid drawn through the vacuum line including a cupped shaped container portion (12) and a lid portion (14) disposed over the container (12) in sealing engagement therewith. The lid (14) includes a fluid inlet (28) and a fluid outlet (30). A filter assembly (16) including a hydrophobic filter (32) and a prefilter (34) filters the particles and aerosols from the fluids passing through the fluid outlet (30). A filter support (18) supports the filters (32, 34, 36) within the filter assembly (16) and includes a cap member (40) spaced below the prefilter (34). The cap member (40) includes an upwardly extending peripheral rim (42) perfecting a seal with the remainder of the filter support (18).Type: GrantFiled: July 2, 1984Date of Patent: December 31, 1985Inventors: Charles von Reis, Karlis Vizulis

Patent number: 4459139Abstract: The disposable filter device of the invention has a housing with a fluid inlet chamber and fluid outlet chamber separated by a hydrophobic filter and having a hydrophilic filter on the inlet chamber side of the hydrophobic filter. In the liquid aspirating system, the disposable filter device is connected between the liquid collection container and the inlet to the aspirator, the hydrophobic filter functioning to prevent the passage of any liquid to the aspirator and the hydrophilic filter functioning to prevent a large accumulation of liquid on the inlet chamber of the filter device and to better assure against any spillage of liquid in the inlet chamber during replacement of the device.Type: GrantFiled: September 14, 1981Date of Patent: July 10, 1984Assignee: Gelman Sciences Inc.Inventors: Charles E. vonReis, Karlis Vizulis
