Abstract
Abstract A sealing device comprising a cap having a closed end and an open end and a retention member engaged with the cap at the open end of the cap. The retention member comprises a plurality of resilient projections which may be defined in the following manner. The projections are inclined away from the body of the retention member and toward the closed end of the cap at an angle alpha ( alpha ) with respect to the body wherein alpha is between about 90 DEG and 135 DEG . The projections have free inner ends defining a restricted opening. And the projections have, at their free inner ends, a chamfered surface facing away from the closed end of the cap which makes an angle theta ( theta ) with respect to the longitudinal axis of the body wherein theta is between about 30 DEG and 50 DEG .

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
176 words
A sealing device comprising: a cap having a closed end and an open end; and a retention member engaged with the cap at the open end thereof; the retention member comprising a generally tubular body having an opening at a first end and, at a second end, a plurality of resilient projections extending toward a longitudinal axis of the body and the cap; the projections: (a) being inclined inwardly of the body away from the first end of the body and toward the closed end of the cap and at an angle α defined on a longitudinal section of the retention member between the projection and the internal wall of the body, wherein α is between about 90° and 135°; (b) having free inner ends defining an opening smaller than the opening at the first end; and (c) having at the free inner ends a chamfered surface facing the first end of the body which makes an angle θ with respect to the longitudinal axis of the body, wherein θ is between about 30° and 50°.
Claim 2
Dependent Claim
176 words
A sealing device comprising: a cap having a closed end and an open end; and a retention member engaged with the cap at the open end thereof; the retention member comprising a generally tubular body having an opening at a first end and, at a second end, a plurality of resilient projections extending toward a longitudinal axis of the body and the cap; the projections: (a) being inclined inwardly of the body away from the first end of the body and toward the closed end of the cap and at an angle α defined on a longitudinal section of the retention member between the projection and the internal wall of the body, wherein α is between about 90° and 135°; (b) having free inner ends defining an opening smaller than the opening at the first end; and (c) having at the free inner ends a chamfered surface facing the first end of the body which makes an angle θ with respect to the longitudinal axis of the body, wherein θ is between about 30° and 50°.
