Appl. No.:

12/398552

Inventors:

William J. Schulz - Baraboo WI, US
Randal D. Leiser - Baraboo WI, US
Steven T. Roule - Covington GA, US

International Classification:

B60K 15/05
B65D 51/24

US Classification:

Abstract:

A cap for a fluid container that includes an outer member and an inner member is provided. The outer member has an inner surface that has at least one finger projecting away therefrom. The inner member is located within the outer member and may rotate relative to the outer members. The inner member also has a recess that has a plurality of ratchet teeth to engage the at least one finger of the outer member. Each ratchet tooth has a torque limiting surface against which the at least one finger is capable of transmitting torque up to a threshold and against which the at least one finger is capable of slipping when the threshold is exceeded. The inner member rotates relative to the outer member when the at least one finger slips against the torque limiting surface.

Abstract:

An electrostatically stimulated air filtering device includes a dielectric filter material having an inlet side and an opposed outlet side for filtering out contaminants in an air stream directed through the device. A grounded control electrode is positioned upstream of the filter material, and an ionizer electrode is positioned between the control electrode and the filter material. A flexible ground electrode is positioned downstream of the filter material, the ground electrode being comprised of an electrically conductive painted coating confined to and in planar contact with the outlet side of the filter material.
