Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
258 words
A tip device for use with a cigarette comprising a sleeve having a first portion at an inner end thereof receiving one end of said cigarette, a plug of porous absorbent material located against said one end, a cylindrical member having a chambered end disposed adjacent said plug and having a centrally disposed passageway having a first end leading to said chamber and having a second end, a first barrier spaced from said second end and located along the axis of said passageway, said first barrier extending from said sleeve and havinG a free edge portion spaced from said sleeve on the opposite side thereof, a second plug of porous absorbent material spaced from said barrier and forming a second chamber therewith, a second barrier in said second chamber and transversely coplanar with said second plug and spaced from said first barrier, said second barrier being affixed to said opposite side of said sleeve and having a free edge portion extending into said second chamber and located at a distance from said opposite side of said sleeve greater than the space between said free edge portion of said first barrier and said opposite side of said sleeve, and a filter enclosed in the outer end of said sleeve and located next to said second plug, said first barrier spacing providing means communicating said passageway to said second chamber whereby a gas drawn from said inner end toward said outer end is accelerated when passing through said passageway and impinged against said barrier prior to reaching said outer end.
Claim 2
Dependent Claim
258 words
A tip device for use with a cigarette comprising a sleeve having a first portion at an inner end thereof receiving one end of said cigarette, a plug of porous absorbent material located against said one end, a cylindrical member having a chambered end disposed adjacent said plug and having a centrally disposed passageway having a first end leading to said chamber and having a second end, a first barrier spaced from said second end and located along the axis of said passageway, said first barrier extending from said sleeve and havinG a free edge portion spaced from said sleeve on the opposite side thereof, a second plug of porous absorbent material spaced from said barrier and forming a second chamber therewith, a second barrier in said second chamber and transversely coplanar with said second plug and spaced from said first barrier, said second barrier being affixed to said opposite side of said sleeve and having a free edge portion extending into said second chamber and located at a distance from said opposite side of said sleeve greater than the space between said free edge portion of said first barrier and said opposite side of said sleeve, and a filter enclosed in the outer end of said sleeve and located next to said second plug, said first barrier spacing providing means communicating said passageway to said second chamber whereby a gas drawn from said inner end toward said outer end is accelerated when passing through said passageway and impinged against said barrier prior to reaching said outer end.
Claim 3
Dependent Claim
24 words
The device of claim 1 wherein said means is an arcuate passageway between said sleeve and first barrier and axially nonaligned with said passageway.
Claim 4
Dependent Claim
14 words
The device of claim 1 where said cylindrical member is of a plastic material.
Claim 5
Dependent Claim
22 words
The device of claim 3 wherein said cylindrical member and said first barrier are integral with one another forming a single element.
Claim 6
Dependent Claim
13 words
The device of claim 4 wherein said element is of a plastic material.
Claim 7
Dependent Claim
10 words
The device of claim 5 wherein said element is hollow.
Claim 8
Dependent Claim
14 words
The device of claim 1 wherein said second barrier is of a plastic material.
Claim 9
Dependent Claim
175 words
A smoke-treating device comprising a sleeve, a cylindrical element within said sleeve and having a chamber at one end thereof having a surface leading to the first end of an axially disposed passageway through said cylindrical element and of a diameter substantially less than that of said element, a first barrier overlapping the other end of said passageway and extending radially inwardly from said sleeve, said first barrier having a portion spaced from said sleeve to form a second axial passageway transversely offset from said first passageway means supporting said first barrier in spaced axial relationship to said other end of said passageway and a second barrier axially spaced from said first barrier and extending radially inwardly from said sleeve in a direction opposite that of said first barrier a distance sufficient to overlap said second passageway, said second barrier having a portion spaced from said sleeve to form a third axial passageway offset from said second passageway, said third passageway being filled by a porous absorbent disklike plug transversely coplanar with said second barrier.
Claim 10
Dependent Claim
175 words
A smoke-treating device comprising a sleeve, a cylindrical element within said sleeve and having a chamber at one end thereof having a surface leading to the first end of an axially disposed passageway through said cylindrical element and of a diameter substantially less than that of said element, a first barrier overlapping the other end of said passageway and extending radially inwardly from said sleeve, said first barrier having a portion spaced from said sleeve to form a second axial passageway transversely offset from said first passageway means supporting said first barrier in spaced axial relationship to said other end of said passageway and a second barrier axially spaced from said first barrier and extending radially inwardly from said sleeve in a direction opposite that of said first barrier a distance sufficient to overlap said second passageway, said second barrier having a portion spaced from said sleeve to form a third axial passageway offset from said second passageway, said third passageway being filled by a porous absorbent disklike plug transversely coplanar with said second barrier.
Claim 11
Dependent Claim
16 words
The invention of claim 8 wherein filter means are disposed at either end of said element.
