Abstract
Abstract A supplemental additive indication cap for installation about a tubular access port of a container, which defines at one end thereof gripper means such as gripper arms for engaging the access port, to prevent removal of the cap after installation. An auxiliary sleeve is carried by the cap for enclosing the gripper means, to prevent the manual disengagement of the gripper means from the access port and removal of the cap, and also to force the gripper means into engagement with the access port. The cap prevents the addition of further additives such as medication to a parenteral solution container after it is installed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
118 words
A supplemental additive indication cap adapted for installation on a tubular access port of a container, said cap defining at one end thereof a plurality of gripper arms, said gripper arms being positioned to engage said tubular access port upon attempted removal of the cap from the access port to prevent removal thereof, and a sleeve, carried by said cap and immovably positioned about said gripper arms, to prevent the manual disengagement of the arms while the cap is positioned on the tubular access port, the innner diameter of said sleeve being proportioned to enhance the gripping of said access port by the gripper arms by preventing the outward displacement of said gripper arms beyond a predetermined limit.
Claim 2
Dependent Claim
118 words
A supplemental additive indication cap adapted for installation on a tubular access port of a container, said cap defining at one end thereof a plurality of gripper arms, said gripper arms being positioned to engage said tubular access port upon attempted removal of the cap from the access port to prevent removal thereof, and a sleeve, carried by said cap and immovably positioned about said gripper arms, to prevent the manual disengagement of the arms while the cap is positioned on the tubular access port, the innner diameter of said sleeve being proportioned to enhance the gripping of said access port by the gripper arms by preventing the outward displacement of said gripper arms beyond a predetermined limit.
Claim 3
Dependent Claim
21 words
The supplemental additive cap of claim 1 in which said gripper arms define barbed portions for gripping said tubular access port.
Claim 4
Dependent Claim
72 words
The supplemental additive indication cap of claim 2, positioned on a tubular access port of a container, the inner diameter of said sleeve being sufficiently small so that the innermost portions of the barbed portions of said gripper arms are positioned about a circumference which is less than the circumference of said tubular access port at the point of engagement with said barbed portions, said barbed portions being adapted to flex inwardly.
Claim 5
Dependent Claim
40 words
The tubular access port and supplemental additive indication cap of claim 3 in which said access port carries at its outer end, within said cap, an elastic, needle-pierceable injection site, whereby said cap prevents access through said elastic injection site.
