Abstract

Abstract Deodorizing is accomplished by contacting odorant, such as that exuded by humans, with solid, essentially non-fluid anion exchanger material in substantially extended form. Articles used in the method are typically those worn on the body, such as hose, or those used to envelop or wipe odoriferous substances and contain anion exchange cotton.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 166 words
A deodorant manufacture configured into a shaped article comprising anion exchange material and normally juxtaposed to a source of odorant of at least secondary status with said anion exchange in contact with said odorant, said anion exchange material being in non-fluid and essentially non-dispersible, substantially extended form and having anion exchange sites capable of substantially sorbing anions from said odorant at the pH existing in the region of contact between said material and said odorant; any components of said material that are endowed with anion exchange sites and are grossly discernible as distinct from one another being, when considered as a group, constrained against any significant flowing so that these components as a group exhibit the characteristic of being non-fluid and essentially non-dispersible; a primary source of odorant being one where odorant is inherent or is, in effect, being generated, and a secondary source of odorant being an odoriferous region of atmosphere immediately adjacent to, and disposed to flow into or out of, a confined space.
Claim 2
Dependent Claim 166 words
A deodorant manufacture configured into a shaped article comprising anion exchange material and normally juxtaposed to a source of odorant of at least secondary status with said anion exchange in contact with said odorant, said anion exchange material being in non-fluid and essentially non-dispersible, substantially extended form and having anion exchange sites capable of substantially sorbing anions from said odorant at the pH existing in the region of contact between said material and said odorant; any components of said material that are endowed with anion exchange sites and are grossly discernible as distinct from one another being, when considered as a group, constrained against any significant flowing so that these components as a group exhibit the characteristic of being non-fluid and essentially non-dispersible; a primary source of odorant being one where odorant is inherent or is, in effect, being generated, and a secondary source of odorant being an odoriferous region of atmosphere immediately adjacent to, and disposed to flow into or out of, a confined space.
Claim 3
Dependent Claim 27 words
The manufacture of claim 1 wherein said article is of the class of articles normally juxtaposed to a body and in contact with odorant while so juxtaposed.
Claim 4
Dependent Claim 37 words
The manufacture of claim 2 wherein said article is of the category customarily worn and so worn as to contact odorant from a region of the body that commonly exudes an odor relatively strongly noticeable to humans.
Claim 5
Dependent Claim 11 words
The manufacture of claim 3 wherein said article is an undergarment.
Claim 6
Dependent Claim 14 words
The manufacture of claim 1 wherein the material comprises weak base anion exchange fabric.
Claim 7
Dependent Claim 45 words
The manufacture of claim 5 wherein said article is of the category customarily worn and is so fabricated and customarily so worn that its anion exchange material contacts odorant from a region of the body that commonly exudes an odor relatively strongly noticeable to humans.
Claim 8
Dependent Claim 11 words
The manufacture of claim 5 wherein said fabric comprises aminated cotton.
Claim 9
Dependent Claim 11 words
The manufacture of claim 6 wherein said fabric comprises aminated cotton.
Claim 10
Dependent Claim 20 words
The manufacture of claim 1 wherin said article is an item adapted to, and normally used to, envelope odoriferous substances.
Claim 11
Dependent Claim 22 words
The manufacture of claim 1 wherein said article is an item adapted to, and normally used to, wipe or scrub odoriferous areas.
