Port and elastic closure

Claim 2

A removable elastic closure for sealing the end of a tubular port comprising: an elongated top member; a guide member, the top member and guide member defining an inner bore; a sleeve member surrounding the guide member having in an unstressed condition an inner circumference that is less than the outer circumference of a top portion of the tubular port; the sleeve member and outer portion of the tubular port cooperating to produce an audible signal when the elastic closure is removed from the tubular port; and the guide member and inner bore cooperating to provide means for hampering the reinsertion of the elastic closure into the tubular port.

Claim 3

The elastic closure of claim 1 wherein the guide member has an outer circumference in an unstressed condition that is less than the inner circumference of the tubular port.

Claim 4

The elastic closure of claim 1 wherein the guide member has a greater length than the sleeve member.

Claim 5

The elastic closure of claim 1 wherein the elongate top member includes at least one rib.

Claim 6

The elastic closure of claim 1 wherein the elastic closure is constructed from an ethylene propylene rubber.

Claim 7

The elastic closure of claim 5 wherein the elastic closure is constructed from a EPDM rubber.

Claim 8

A port and closure assembly for a solution container comprising: a tubular port for providing access to fluid with the solution container, the tubular port including an elongated bore, an outer wall defining the bore, a partition wall located in the bore, and a rib member circumscribing the outer wall; an elastomeric closure for removably sealing the tubular port, including a guide member adapted to be received within the bore, and a sleeve for sealingly surrounding a portion of the outer wall of the tubular port; and the sleeve having an inner circumference in an unstressed state that is less than the outer circumference of the rib member, the sleeve having fingers that extend below the rib member when the closure seals the port, the fingers having an outer circumference that is smaller than the outer circumference of a portion of the sleeve that circumscribed the rib when the closure seals the port, the sleeve and tubular port cooperating to produce a Chinese finger effect and an audible signal when the closure is removed form the port if the partition wall is not pierced.

Claim 9

A port and closure assembly for a solution container comprising: a tubular port for providing access to fluid with the solution container, the tubular port including an elongated bore, an outer wall defining the bore, a partition wall located in the bore, and a rib member circumscribing the outer wall; an elastomeric closure for removably sealing the tubular port, including a guide member adapted to be received within the bore, and a sleeve for sealingly surrounding a portion of the outer wall of the tubular port; and the sleeve having an inner circumference in an unstressed state that is less than the outer circumference of the rib member, the sleeve having fingers that extend below the rib member when the closure seals the port, the fingers having an outer circumference that is smaller than the outer circumference of a portion of the sleeve that circumscribed the rib when the closure seals the port, the sleeve and tubular port cooperating to produce a Chinese finger effect and an audible signal when the closure is removed form the port if the partition wall is not pierced.

Claim 10

The port and closure assembly of claim 7 wherein the guide member has a greater length than the sleeve.

Claim 11

The port and closure assembly of claim 7 wherein the elastomeric closure includes a gripping member.

Claim 12

The port and closure assembly of claim 7 wherein the closure is constructed from an ethylene propylene rubber.

Claim 13

The port and closure assembly of claim 10 wherein the closure is constructed from a EPDM rubber.

Claim 14

The port and closure assembly of claim 7 wherein the inner circumference in unstressed condition of the sleeve is less than the outer circumference of the outer wall of the tubular port.

Claim 15

The port and closure assembly of claim 9 wherein the gripping member includes a tubular bore extending from an opening in a top of the gripping member substantially the entire length of the closure.

Claim 16

A port and closure assembly for a solution container comprising: a tubular port for providing access to fluid within the solution container including, an elongated bore, an outer wall defining the bore, a rib circumscribing the outer wall, and a partition wall for dividing the elongated bore into an upper and lower bore; an elastomeric closure for removably sealing the tubular port, including a guide member adapted to be received within the upper bore, gripping means for grasping the elastomeric closure, and a sleeve for sealingly surrounding a portion of the outer wall, the sleeve having in an unstressed condition an inner circumference that is less than the outer circumference of the rib circumscribing the outer wall of the tubular port; and the sleeve and rib cooperating to produce a Chinese finger effect and an audible signal when the closure is removed from the tubular port if the partition wall is intact.

Claim 17

A port and closure assembly for a solution container comprising: a tubular port for providing access to fluid within the solution container including, an elongated bore, an outer wall defining the bore, a rib circumscribing the outer wall, and a partition wall for dividing the elongated bore into an upper and lower bore; an elastomeric closure for removably sealing the tubular port, including a guide member adapted to be received within the upper bore, gripping means for grasping the elastomeric closure, and a sleeve for sealingly surrounding a portion of the outer wall, the sleeve having in an unstressed condition an inner circumference that is less than the outer circumference of the rib circumscribing the outer wall of the tubular port; and the sleeve and rib cooperating to produce a Chinese finger effect and an audible signal when the closure is removed from the tubular port if the partition wall is intact.

Claim 18

The port and closure assembly of claim 14 wherein the gripping means includes a means for hampering the reinsertion of the port, the means including a tubular bore.

Claim 19

The port and closure assembly of claim 14 wherein the gripping means includes at least one rib member.

Claim 20

The port and closure assembly of claim 14 wherein the closure is constructed from an ethylene propylene rubber.
