Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
166 words
A portal bushing for use with a reservoir body in a reservoir assembly to provide access thereinto for an applicator, said bushing comprising: a generally cylindrical body with a passage therethrough between a first axial end and a second axial end; means for affixing a seal around the external periphery of said cylindrical body, said affixing means being disposed on said first axial end; and a lip for interlocking with the reservoir body and means for penetrating into the reservoir body, said lip and said penetrating means being disposed on the external periphery of said cylindrical body between said first axial end and said second axial end, said lip being engageable with a groove in the reservoir body to translate thrust forces therebetween and said penetrating means being engageable into a penetrable portion on the reservoir body to translate torsional forces therebetween, said lip and said penetrating means being effective to retain said cylindrical body in the reservoir body with no continual stress being exerted therebetween.
Claim 2
Dependent Claim
166 words
A portal bushing for use with a reservoir body in a reservoir assembly to provide access thereinto for an applicator, said bushing comprising: a generally cylindrical body with a passage therethrough between a first axial end and a second axial end; means for affixing a seal around the external periphery of said cylindrical body, said affixing means being disposed on said first axial end; and a lip for interlocking with the reservoir body and means for penetrating into the reservoir body, said lip and said penetrating means being disposed on the external periphery of said cylindrical body between said first axial end and said second axial end, said lip being engageable with a groove in the reservoir body to translate thrust forces therebetween and said penetrating means being engageable into a penetrable portion on the reservoir body to translate torsional forces therebetween, said lip and said penetrating means being effective to retain said cylindrical body in the reservoir body with no continual stress being exerted therebetween.
Claim 3
Dependent Claim
15 words
The portal bushing of claim 1 wherein said lip is annularly disposed about said bushing.
Claim 4
Dependent Claim
30 words
The bushing of claim 1 wherein said penetrating means includes teeth, said teeth being arranged to pierce the penetrable portion on the reservoir body upon assembly of said bushing therewith.
Claim 5
Dependent Claim
30 words
The bushing of claim 3 wherein said teeth are disposed about the full periphery of said bushing, said teeth presenting a bite parallel to the longitudinal axis of said bushing.
Claim 6
Dependent Claim
32 words
The bushing of claim 3 wherein said teeth are disposed in groups periodically about the periphery of said bushing, said teeth presenting a bite parallel to the longitudinal axis of said bushing.
Claim 7
Dependent Claim
39 words
The bushing of claim 1 wherein said lip is annularly disposed about said bushing and said penetrating means includes teeth, said teeth being arranged to pierce the penetrable portion on the reservoir body upon assembly of said bushing therewith.
Claim 8
Dependent Claim
30 words
The bushing of claim 6 wherein said teeth are disposed about the full periphery of said bushing, said teeth presenting a bite parallel to the longitudinal axis of said bushing.
Claim 9
Dependent Claim
32 words
The bushing of claim 6 wherein said teeth are disposed in groups periodically about the periphery of said bushing, said teeth presenting a bite parallel to the longitudinal axis of said bushing.
Claim 10
Dependent Claim
185 words
A portal bushing for use with a reservoir body in a reservoir assembly to provide access thereinto for an applicator, said bushing comprising: a generally cylindrical body with a passage therethrough between a first axial end and a second axial end; means for affixing a seal around the external periphery of said cylindrical body, said affixing means being disposed on said first axial end; means for interconnecting the reservoir assembly to the applicator, said interconnecting means being disposed on said second axial end; and a lip for interlocking with the reservoir body and means for penetrating into the reservoir body, said lip and said penetrating means being disposed on the external periphery of said cylindrical body between said first axial end and said second axial end, said lip being engageable with a groove in the reservoir body to translate thrust forces therebetween and said penetrating means being engageable into a penetrable portion on the reservoir body to translaTe torsional forces therebetween, said lip and said penetrating means being effective to retain said cylindrical body in the reservoir body with no continual stress being exerted therebetween.
Claim 11
Dependent Claim
185 words
A portal bushing for use with a reservoir body in a reservoir assembly to provide access thereinto for an applicator, said bushing comprising: a generally cylindrical body with a passage therethrough between a first axial end and a second axial end; means for affixing a seal around the external periphery of said cylindrical body, said affixing means being disposed on said first axial end; means for interconnecting the reservoir assembly to the applicator, said interconnecting means being disposed on said second axial end; and a lip for interlocking with the reservoir body and means for penetrating into the reservoir body, said lip and said penetrating means being disposed on the external periphery of said cylindrical body between said first axial end and said second axial end, said lip being engageable with a groove in the reservoir body to translate thrust forces therebetween and said penetrating means being engageable into a penetrable portion on the reservoir body to translaTe torsional forces therebetween, said lip and said penetrating means being effective to retain said cylindrical body in the reservoir body with no continual stress being exerted therebetween.
Claim 12
Dependent Claim
186 words
A portal bushing for use with a reservoir body in a reservoir assembly to provide access thereinto for an applicator, said bushing comprising: a generally cylindrical body with a passage therethrough between a first axial end and a second axial end; means for affixing a seal around the external periphery of said cylindrical body, said affixing means being disposed on said first axial end; thread means for interconnecting the reservoir assembly to the applicator, said thread means being disposed on said second axial end; and a lip for interlocking with the reservoir body and means for penetrating into the reservoir body, said lip and said penetrating means being disposed on the external periphery of said cylindrical body between said first axial end and said second axial end, said lip being engageable with a groove in the reservoir body to translate thrust forces therebetween and said penetrating means being engageable into a penetrable portion on the reservoir body to translate torsional forces therebetween, said lip and said penetrating means being effective to retain said cylindrical body in the reservoir body with no continual stress being exerted therebetween.
Claim 13
Dependent Claim
186 words
