Claim 9

The combined additive and administration port as defined in claim 3 wherein said tubular walled port defines a ledge surface and said annular flange of said guide member contacts said ledge surface.

Claim 10

The combined additive and administration port as defined in claim 2 wherein said outer resealable member is defined by a base portion for attachment to said inner guide member and includes a cover portion hinged to said base portion.

Claim 11

The combined additive and administration port as defined in claim 9 further including means to releasably secure said cover portion to said base.

Claim 12

The combined additive and administration port as defined in claim 1 wherein said tubular walled port includes an end wall placed outside the comfines of said container and said outer resealable member is secured to said end wall at a side opposite said container.

Claim 13

The combined additive and administration port as defined in claim 11 wherein said outer resealable member includes a reseal button.

Claim 14

The combined additive and administration port as defined in claim 12 wherein said reseal button is mechanically secured to said tubular walled port.

Claim 15

The combined additive and administration port as defined in claim 13 wherein said resealable member includes a port cover and said tubular walled port is sealed in part by said port cover and said reseal button is secured to said cover.

Claim 16

The combined additive and administration port as defined in claim 14 wherein said tab portion is directly attached to said reseal button.

Claim 17

The combined additive and administration port as defined in claim 14 wherein said tab portion is directly attached to said port cover.

Claim 18

The combined additive and administration port as defined in claim 14 wherein said reseal button is secured in said cover by means of a groove in said reseal button and a complementary annulus in said cover.

Claim 19

The combined additive and administration port as defined in claim 14 wherein said cover includes a preweakened portion for removal from said tubular walled port.

Claim 20

A unitary additive and administration port for a container having flexible wall portions adapted to receive a sterile intravenous liquid comprising: a semirigid tubular walled port in communication with the inside of said container and sealed to said flexible wall portions; an inner diaphragm member forming a portion of said port and sealing the inside of said container to outside atmosphere; said tubular walled port and said diaphragm member composed of the same material as said flexible wall portions of said container; an outer resealable and pierceable member removably secured to said port and positioned from said diaphragm member in a direction opposite the inside of said container; and a handle portion operatively connected to said resealable member for removing said resealable member from said port.

Claim 21

A unitary additive and administration port for a container having flexible wall portions adapted to receive a sterile intravenous liquid comprising: a semirigid tubular walled port in communication with the inside of said container and sealed to said flexible wall portions; an inner diaphragm member forming a portion of said port and sealing the inside of said container to outside atmosphere; said tubular walled port and said diaphragm member composed of the same material as said flexible wall portions of said container; an outer resealable and pierceable member removably secured to said port and positioned from said diaphragm member in a direction opposite the inside of said container; and a handle portion operatively connected to said resealable member for removing said resealable member from said port.

Claim 22

The combined additive and administration port as defined in claim 19 wherein said flexible wall portion of said container, said tubular walled port and said diaphragm member are composed of a thermoplastic material and said resealable member includes a reseal button composed of a rubber containing material.

Claim 23

The combined additive and administration port as defined in claim 19 further including an inner guide member defining a tubular wall and central passageway and said inner diaphragm member seals said passageway.

Claim 24

The combined additive and administration port as defined in claim 21 wherein said resealable member includes a port cover, said inner guide member and said port cover being sealed as one integral component with said port cover having preweakened portions for forceable removal.
