Abstract
Abstract A separation-resistant capsule for containing, for example, oral medication, having a sealing band established between telescopically engageable body and cap portions of the capsule. The sealing band is provided by conforming mating tapers on both said portions rendering the capsule substantially airtight when said portions are fully telescopically engaged with one another.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
184 words
A separation-resistant capsule comprising: a tubular body having an open end and a closed end; an external tapered sealing zone on said body adjacent its said open end, the diameter of said tapered zone increasing progressively towards said open end; a cap within which said body is telescopically installable having an open end and a closed end; an annular constriction in said cap intermediate its said open and closed ends; an internal tapered sealing zone in said cap intermediate its said constriction and closed end, the diameter of said tapered zone increasing progressively towards said closed end of the cap; said sealing zones being conformingly tapered and dimensioned to mate with each other and form a broad, substantially hermetic, tapered, seal when the body is fully telescopically installed in the cap, and a skirt on said cap extending from its said constriction to its said open end, said skirt flaring towards said open end, the maximum external diameter of the body sealing zone being less than the internal diameter of the open end of the cap but exceeding the internal diameter of said constriction.
Claim 2
Dependent Claim
184 words
A separation-resistant capsule comprising: a tubular body having an open end and a closed end; an external tapered sealing zone on said body adjacent its said open end, the diameter of said tapered zone increasing progressively towards said open end; a cap within which said body is telescopically installable having an open end and a closed end; an annular constriction in said cap intermediate its said open and closed ends; an internal tapered sealing zone in said cap intermediate its said constriction and closed end, the diameter of said tapered zone increasing progressively towards said closed end of the cap; said sealing zones being conformingly tapered and dimensioned to mate with each other and form a broad, substantially hermetic, tapered, seal when the body is fully telescopically installed in the cap, and a skirt on said cap extending from its said constriction to its said open end, said skirt flaring towards said open end, the maximum external diameter of the body sealing zone being less than the internal diameter of the open end of the cap but exceeding the internal diameter of said constriction.
Claim 3
Dependent Claim
51 words
A separation-resistant capsule as claimed in claim 1 wherein: said skirt is differentially flared in two discrete portions between said constriction and the open end of the cap, the degree of flaring being greater in the portion adjacent said constriction than in the portion adjacent the open end of the cap.
Claim 4
Dependent Claim
24 words
A separation-resistant capsule as claimed in claim 1 wherein: said sealing zone on said body extends to the rim of its said open end.
Claim 5
Dependent Claim
41 words
A separation-resistant capsule as claimed in claim 1 wherein: said body is externally tapered over its full length from its said open end to its said closed end; said body sealing zone being constituted by a portion of said tapered body.
