Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
188 words
A holder for removably supporting a filter element comprising: a first component comprising a funnel-shaped base including a centrally apertured filter member support section, a hollow stem depending from said support section, a surface formed on said support section opposite said stem adapted to contact and support one side of a peripheral portion of said filter element; a second component comprising a centrally apertured cap including a surface adapted to contact the other side of said peripheral portion of said filter element; and means for removably securing said first and second components together including a tapered peripheral shoulder formed on one of said components, and a rounded resilient re-entrant lip formed about the periphery of the other one of said components and having a plurality of narrow slots radially spaced about said lip enabling said lip to resiliently engage the tapered portion of said shoulder on said one of said components, said taper being in a direction to provide a component of the force of the resilient engagement in a direction urging said first and second components together for clamping said peripheral portion of said filter member therebetween.

Claim 3
Dependent Claim
35 words
The holder of claim 1 wherein the area of said surface of said first component contacting said filter element is greater than the area of said surface of said second component contacting said filter element.
Claim 4
Dependent Claim

Claim 6
Dependent Claim
29 words
The holder of claim 1 wherein said support section of said first component is formed with a series of spaced ribs for providing intermediate support of said filter element.
