Patent number: 8191469Abstract: In one aspect, a bracket for evacuating a storage bag having a one-way valve element is provided that has parallel first and second flat panels that delineate a gap. A bag can be placed into the gap such that the valve element on the bag aligns with an aperture disposed through the first panel. To evacuate the bag, a nozzle of an evacuation device can be inserted through the aperture and pressed against the bag sidewall about the valve element. When the evacuation device is activated, the sidewall of the bag is pulled against the rim of the nozzle and air is drawn through the valve element. In another embodiment, the nozzle can be pressed against the first panel around the aperture. In another aspect, the bracket can be included as part of a handheld evacuation device.Type: GrantFiled: May 19, 2008Date of Patent: June 5, 2012Assignee: The Glad Products CompanyInventors: Carl L. Bergman, Chinto Benjamin Gaw

Patent number: 7726880Abstract: The flexible storage bag includes overlaying first and second sidewalls defining an internal volume that can be accessed from an open top edge. To evacuate air from the internal volume after the open top edge has been closed, the bag includes a one-way valve element attached to the first sidewall and communicating with the internal volume. To prevent the one-way valve element from becoming clogged by the opposing second sidewall, the bag also includes a clearance member that maintains at least a partial clearance between the first and second sidewalls proximate the valve element. The clearance member can take many forms such as a textured portion on the second sidewall that includes evacuation passages which provide air in the internal volume access to the valve element, a permeable element covering the valve element, and a rigid or compressible structure that spaces the second sidewall from the valve element.Type: GrantFiled: June 29, 2004Date of Patent: June 1, 2010Assignee: The Glad Products CompanyInventors: Dean Arthur Zimmerman, Carl Louis Bergman, Chinto Benjamin Gaw, Michael G. Borchardt

Patent number: 7360724Abstract: A nozzle is provided for use in a dynamic electrostatic air filter, in which the nozzle includes an internal electrode that charges a semiconductive liquid, and includes an external electrode that assists in breaking the liquid into droplets in a predetermined direction. Banks of multiple nozzles are also disclosed, which are separated by a charged “separation electrode” to prevent interference with spray patterns between adjacent banks. An electrostatic fountain is also disclosed which discharges a fragrance, or an inhalable medicine.Type: GrantFiled: October 20, 2004Date of Patent: April 22, 2008Assignee: The Procter & Gamble CompanyInventors: Alan David Willey, Vladimir Gartstein, Chinto Benjamin Gaw, John Rolland Shaw, William Richard Mueller, Krista Beth Comstock

Patent number: 7160391Abstract: A nozzle spray head is provided for use in a dynamic electrostatic air filter, in which the nozzle spray head assembly exhibits multiple nozzle orifices as outlet ports, which extend from the bottom of the nozzle body such that the distances between the outlet ports and a target member are not constant. The charged multiple outlet ports exhibit a more uniform electric field at their tips, thereby enabling a better and more uniform spray pattern to be emitted by each of the individual outlet ports. In one embodiment, the outlet ports are grouped in concentric circles, in which the innermost circle comprises outlet ports of the greatest lengths, and the outermost circle comprises outlet ports of the smallest lengths.Type: GrantFiled: October 20, 2004Date of Patent: January 9, 2007Assignee: The Procter & Gamble CompanyInventors: Alan David Willey, Vladimir Gartstein, Chinto Benjamin Gaw, Jean Angela Jefferson, Krista Beth Comstock

Patent number: 6656253Abstract: An apparatus for removing particles from air, including an inlet for receiving a flow of air, a first chamber in flow communication with the inlet, wherein a charged spray of semiconducting fluid droplets having a first polarity is introduced to the air flow so that the particles are electrostatically attracted to and retained by the spray droplets, and an outlet in flow communication with the first chamber, wherein the air flow exits the apparatus substantially free of the particles. The first chamber of the apparatus further includes a collecting surface for attracting the spray droplets, a power supply, and a spray nozzle connected to the power supply for receiving fluid and producing the spray droplets therefrom. The apparatus may also include a second chamber in flow communication with the inlet at a first end and the first chamber at a second end, wherein particles entrained in the air flow are charged with a second polarity opposite the first polarity prior to the air flow entering the first chamber.Type: GrantFiled: October 29, 2002Date of Patent: December 2, 2003Assignee: The Procter & Gamble CompanyInventors: Alan David Willey, Vladimir Gartstein, Chinto Benjamin Gaw
