Abstract
Abstract An adsorbent cartridge having an elongated hollow cylindrical body member fabricated of polyethylene, polyester or polypropylene, spun-bonded polyolefin membranes closing the open ends of the body member, adsorbent within the body member, and raised splines or ribs extending longitudinally on the outer surface of the body member for causing the cartridge to have a different feel than a medicinal capsule with which it may be packaged.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
180 words
An adsorbent cartrige for placement in a container of pills, medicinal capsules, or the like, with which it is packaged and which can be distinguished from said pills or capsules by feel comprising a rigid plastic body member having first and second ends and an annular central body portion therebetween, an outer surface and an internal surface on said central body portion, circumferentially spaced elongated ribs extending longitudinally on said central body portion between said first and second ends and formed integrally with said central body portion and projecting radially outwardly from said outer surface of said central body portion, said central body portion being completely closed and impermeable to gases between said first and second ends, said adsorbent cartridge being distinguishable from medicinal pills or capsules by detecting the difference therebetween when said central body portion with said ribs thereon is grasped, an opening on at least one of said ends, a planar gas-permeable disc-like membrane closing said opening, and adsorbent within said central body portion of said body member and in direct contact with said internal surface thereof.
Claim 2
Dependent Claim
180 words
An adsorbent cartrige for placement in a container of pills, medicinal capsules, or the like, with which it is packaged and which can be distinguished from said pills or capsules by feel comprising a rigid plastic body member having first and second ends and an annular central body portion therebetween, an outer surface and an internal surface on said central body portion, circumferentially spaced elongated ribs extending longitudinally on said central body portion between said first and second ends and formed integrally with said central body portion and projecting radially outwardly from said outer surface of said central body portion, said central body portion being completely closed and impermeable to gases between said first and second ends, said adsorbent cartridge being distinguishable from medicinal pills or capsules by detecting the difference therebetween when said central body portion with said ribs thereon is grasped, an opening on at least one of said ends, a planar gas-permeable disc-like membrane closing said opening, and adsorbent within said central body portion of said body member and in direct contact with said internal surface thereof.
Claim 3
Dependent Claim
29 words
An adsorbent cartridge as set forth in claim 1 wherein said ribs do not extend all of the way to at least one of said first and second ends.
Claim 4
Dependent Claim
25 words
An adsorbent cartridge as set forth in claim 1 wherein said ribs do not extend all of the way to said first and second ends.
Claim 5
Dependent Claim
23 words

Claim 6
Dependent Claim
50 words
An adsorbent cartridge as set forth in claim 1 wherein said ribs are of triangular cross-sectional configuration, each of said ribs having sides which have first ends which merge with said outer surface and which converge outwardly away from said outer surface and which terminate at a sharp outer edge.
Claim 7
Dependent Claim
26 words
An adsorbent cartridge as set forth in claim 5 wherein said triangular ribs have end portions which include points in addition to said sharp outer edges.
Claim 8
Dependent Claim

Claim 9
Dependent Claim
28 words
An adsorbent cartridge as set forth in claim 1 including a second opening at the other of said ends, and a second gas-permeable membrane closing said second opening.
Claim 10
Dependent Claim
50 words
An adsorbent cartridge as set forth in claim 8 wherein said ribs are of triangular cross-sectional configuration, each of said ribs having sides which have first ends which merge with said outer surface and which converge outwardly away from said outer surface and which terminate at a sharp outer edge.
Claim 11
Dependent Claim
26 words
An adsorbent cartridge as set forth in claim 9 wherein said triangular ribs have end portions which include points in addition to said sharp outer edges.
Claim 12
Dependent Claim
28 words

Claim 18
Dependent Claim
190 words
An adsorbent cartridge for placement in a container of pills, capsules, or the like, with which it is packaged and which can be distinguished from said pills or capsules by feel comprising a rigid plastic body member having first and second ends and an annular central body portion therebetween, an outer surface and an internal surface on said central body portion, a plurality of circumferentially spaced elongated ribs extending longitudinally on said central body portion between said first and second ends and formed integrally with said central body portion and projecting radially outwardly from said outer surface of said central body portion, said central body portion being completely closed and impermeable to gases between said first and second ends, said adsorbent cartridge being distinguishable from medicinal pills or capsules by detecting the difference therebetween when said central body portion with said ribs thereon is grasped, an opening on at least one of said ends, a planar gas-permeable disc-like plastic membrane sealed by fusion across said opening for closing said opening, and adsorbent within said central body portion of said body member and in direct contact with said internal surface thereof.
