Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
86 words
A port and closure assembly for a solution container comprising: a port including an opening, a tubular bore, an outer wall defining the tubular bore, and a rib circumscribing the outer wall; a closure including a cap having an inner circumference substantially equal to the outer circumference of the rib of the outer wall of the port so that a friction fit is produced when the cap seals the opening of the port; and the closure further including a coating sealing the cap to the port.
Claim 2
Dependent Claim
86 words
A port and closure assembly for a solution container comprising: a port including an opening, a tubular bore, an outer wall defining the tubular bore, and a rib circumscribing the outer wall; a closure including a cap having an inner circumference substantially equal to the outer circumference of the rib of the outer wall of the port so that a friction fit is produced when the cap seals the opening of the port; and the closure further including a coating sealing the cap to the port.
Claim 3
Dependent Claim
14 words
The port and closure assembly of claim 1 wherein the port is hermetically sealed.
Claim 4
Dependent Claim
36 words
The port and closure assembly of claim 1 wherein: the port includes a second rib located below the first rib; and the cap sits on the second rib when it seals the opening of the port.
Claim 5
Dependent Claim
14 words
The port and closure assembly of claim 1 wherein the coating is color coded.
Claim 6
Dependent Claim
24 words
The port and closure assembly of claim 1 wherein the coating leaves a color coded band around the port after the closure is removed.
Claim 7
Dependent Claim
17 words
The port and closure assembly of claim 1 wherein the coating is constructed from an organic plasticsol.
Claim 8
Dependent Claim
23 words
The port and closure assembly of claim 3 wherein the coating extends along the port below the second rib of the outer wall.
Claim 9
Dependent Claim
65 words
A closure for a port having a tubular opening and a rib circumscribing an outer wall of the port comprising: a cap cooperating with the rib so that a friction fit is created when the cap covers the tubular opening of the port; and a coating for sealing the cap to the port, the coating providing means for determining if the closure has been opened.
Claim 10
Dependent Claim
65 words
A closure for a port having a tubular opening and a rib circumscribing an outer wall of the port comprising: a cap cooperating with the rib so that a friction fit is created when the cap covers the tubular opening of the port; and a coating for sealing the cap to the port, the coating providing means for determining if the closure has been opened.
Claim 11
Dependent Claim
12 words
The closure of claim 8 wherein the closure hermetically seals the port.
Claim 12
Dependent Claim
23 words
The closure of claim 8 wherein: the port includes a second rib; and the coating extends along the port below the second rib.
Claim 13
Dependent Claim
16 words
The closure of claim 10 wherein the cap sits on the second rib of the port.
Claim 14
Dependent Claim
24 words
The closure of claim 8 wherein the coating is so constructed and arranged that a band circumscribes the port after the closure is removed.
Claim 15
Dependent Claim
11 words
The closure of claim 11 wherein the band is color coded.
Claim 16
Dependent Claim
14 words
The closure of claim 8 wherein the coating is constructed from an organic plasticsol.
Claim 17
Dependent Claim
75 words
A closure for hermetically sealing a port having a tubular opening and at least one rib circumscribing an outer wall of the port comprising: a cap cooperating with a first rib so that a friction fit is created when the cap covers the tubular opening of the port; a coating for sealing the cap to the port; and the coating and cap cooperating to provide means for determining if the hermetic seal has been opened.
Claim 18
Dependent Claim
75 words
A closure for hermetically sealing a port having a tubular opening and at least one rib circumscribing an outer wall of the port comprising: a cap cooperating with a first rib so that a friction fit is created when the cap covers the tubular opening of the port; a coating for sealing the cap to the port; and the coating and cap cooperating to provide means for determining if the hermetic seal has been opened.
Claim 19
Dependent Claim
22 words
The closure of claim 15 including means for leaving a band around the port after the closure is removed from the port.
Claim 20
Dependent Claim
11 words
The closure of claim 16 wherein the band is color coded.
