2,693,1a9 issued November 2, 1954 or 3,509,879 issued May 5, 1970. During administration of the fluid, such flexible con-tainers will colla~se due to atmospheric pressure and hence it is not necessary eO admit air wi~hin the container. Consequent-ly, a po~ential source of contamination can be eliminated or minimized. However9 such flexible containers are difficult to fill and seal and when hung on a hospital hanger for adminis-tration~ because of their flexible nature causing distor~ion, it is difficult to read the meniscus which is necessary in order to determine the amount of fluid being administered to the patient.
SUMMARY OF THE INVENTIO~ ~ -The present invention comprises a flexible container for medical fluids made of a chemically inert plastic material and having a pair of opposed walls sealed along the entire per-i~eter thereof to form the container. The container also in-cludes a reinforced hanger portion at one end including a stiff ^ card encapsulated within an envelope formed by the sealed opposed walls, the reinforced hanger portion minimizing distortion of ;-the container so that the meniscus formed by the fluid therein can be easily read and the amount of fluid being administered can be accurately determined. A combined fill and administration port i9 disposed on the end of the container opposite the hanger portion and includes a fill port formed by a semirigid tubular portion having open ends. The tubular portion is disposed be- ;
tween the opposed walls of the container and sealed therein to ~i provide communication into the interior of the container. An ;^ annular flange, perpendicular to the axis of the tubular por-tion, extends from the end of the tubular portion spaced away from the container. The administration port includes a close fitting tubular section inserted into the tubular portion of the fill port having a passageway therethrough with an open end spaced away Erom the container. The other end of the passage-:

way is closed by a puncturable diaphraghm. The end of the tubular section of the administration port spaced away from the container has an annular flange also perpendicular to the axis of the tubular portion and the tubular section and extend-ing therefrom. The flange of the tubular section is coextensive with the flange of the fill port. A cover for sealing the com-bined fill and administration port is provided, the cover includ-in8 a body having an annular flange extending therefrom coexten-sive wlth the flanges of the fill and administration port. The respective flanges of the fill port, administration port and cover are sealed together to seal the container. The cover includes a weakening ring formed in the inner surface of the cover radially inwardly of the cover flange and adjacent the ~, :
administration port, and an integral handle extending perpen-dicularly away from the outer surface of the cover, immedia~ely ~; . .
opposite the weakening ring9 which handle and weakening ring facilitate removal of the cover.

Detailed Description - Referxing to the drawings, Figure 1 illustrates a flexible, collapsible container 10 of the present invention suitable for medical fluids. The container 10 includes a sealed flexible bag 11 made of a chemically ! inert, plastic materlal such as polyvinyl chloride.
The bag 11 includes a pair of opposed walls 12, 13 sealed along the perimeter 14 thereof to form the container 10.
At one end 15 of the bag 11 a reinforced hanger portion 16 is fabricated. The xeinforced hanger portion 16 includes a stiff reinforcing card 17 encapsulated within the envelope 18 formed by the two side walls 12, 13 when they are sealed together. Extending from the envelope ~ 18 ls a flap 19 formed by sealing of the two shee~s or ; lS extruded tube of plastic together and having an opening 20 therein for hanging of the bag in use. Reinforcing ribs 21, 22 are formed during the sealing process to provide extra stiffness to the hanger portion -17. The stiff card 17 encapsulated within the hanger portion 16 of the container 10 provldes reinforcement to the hanger ` portion 16 as well as containing label copy. Flexible contaLners when suspended for use, tend to stretch and ; distort so that measurement of the fluid level within the container is difficult. When the container 10 is sus-pended from a hospital qtandard, the reinforced hanger portion 16 acts to prevent distortion of the bag 11 .. ' _ 4 _ ~; ' . -' .

; and therefore provides a well defined meniscus for . . .
improved readability of the calibrations and fluid level.
Of course, the opening 20 in the flap 19 can have a variety of shapes.
^ 5 Depending on the end use intended for the -' conta~ner 10, whether for irrigating 1uids or intra-- venous fluidsJ one or more ports can be incorporated in the bag 11. As illustrated, on the end 23 of the bag 11 : opposite the hanger portion 19 are positioned two ports, .:
;~- 10 a fill and admlnistration port 24 and an additive port 45.
The fill and administration port 24 comprises a fill port 25 formed by a semi-rigid tubular portion 26 having open ~, ends 27 and 28, the tubular portion 26 extendlng within !;'~ the bag 11 to provide communlcation into the interior 15 of the bag 11. An annular flange 29 extends from the end .
28 of the fill port 26. The fill port 25 is sealad in .
place during fabrication of the bag 11. The tubular . portion 26 of the fill port 25 is positioned in place ~; between two sheets of plastic forming the side walls 12, 13 of the bag 11. As the perimeter 14 of the opposed ~ walls 12, 13 is sealed together, the fill port 25 will .~ be sealed in place, the port 25 providing-communication ~ :
- into the interior of the bag 11 for filling purposes. .~:
After the bag 11 is filled through the fill port 25, an administration port 30 is inserted into the fill port 25 and sealed thereto. The administration port 30 , ~ .

! includes a tubular section 31 having a passageway 32 therethrough with an open end 33/ the other end 34 of the passageway 32 being closed by a puncturable dlaphragm 35. Extending from the open end 33 of the administration port 30 is an annular flange 36 adapted to mate with the flange 29 of the fill port 25, The administration port 30 is sealed by a cover 37 which comprises a body 38 having an annular flange 39 extending therefrom coextensive with the flange 29 of the fill port and the flange 36 of the administration port 30 and including a handle 40 extendlng therefrom~ A weakened portion 41 is formed in ; the cover 37 to facilitate removal. The fill port 25, administration port 30 and cover 37 are sealed together . along the flanges 29, 36, 39 thereof after assembly. If :: -; 15 the container 10 is to be utilized for a fluid to which -~
no additional medicament is to be added, the fill and ;
administration port 24 is sufficient and no other ports need be added, The additive port 45 is positioned on one of the side walls 12/ 13 and sealed thereto and comprises a - tubular sec~ion 46 having an open end ~7 and a closed .
- end 48 together with a passage 49 therethrough. The closed end 48 is spaced away from the open end 47 and i forms a puncturable diaphragm 50 to ~acilitate entry of a needle or cannula into the bag 11. An intergral cover 51 is positioned over the tubular section 46, the . . .

' 5 A handle base 57 extend~ from the end wall 54 and includes a handle 58 extending therefrom. The flange 55 of the cover 51 is sealed directly to one o~ the bag 11 walls 12, 13 so that the wall 12, 13 closes off the passage :. ...
;~ and further, forms a puncturable membrane. As is apparent, since the puncturable diaphragm 50 of the additive port 45 is spaced away from the open end 47, the port 45 allows .. . . .
piercing with a long hypodermic needle and minimizes the .
possibility of piercing the opposite wall of the container 10. Additionally, once sterilized, the~ cover 51 will ,~ 15 maintain sterility so that upon use, there isno need to swab the puncturable diaphragm 50 with~a bactericide.
The container 10 can be fabricated to form a bag ll from two sheets of plastic sealed together pre-ferably by heat sealing methods. Prior to sealing ~he perimeter 14 of the opposed walls 12, 13 to ~orm the bag 11, the tubular portion 26 of the fill por~ 25 is `' positioned between the two sheets of plastic and sealed ; in place as previously described.

In use, the cover 37 of the ad~inistration port 30 is removed and the piercing cannula of an administration set is inserted therein, piercing the diaphragm 35 and -thereby providing communication with the inside of the bag 11 so that fluid can flow rom the container 10 - through the tubing of the administratiQn set (not shown) to the patient~ As the fluid i8 administered, the container 10 will collapse due to atmospheric pressure. Accordingly~
no air vent is required, thereby minimizing the . . . . .
possibility of contamination. Likewise, the reinforced hanger portion 16 and particularly the card 17 which is encapsulated therein will prevent the container 10 from -~
distorting so that the meniscus formed by the fluid can be easily read and the amount of fluid being administered ,, , :
to the patient can be easily and accurately determined.
As previously described, if the container 10 iB

In use, the cover 37 of the ad~inistration port 30 is removed and the piercing cannula of an administration set is inserted therein, piercing the diaphragm 35 and -thereby providing communication with the inside of the bag 11 so that fluid can flow rom the container 10 - through the tubing of the administratiQn set (not shown) to the patient~ As the fluid i8 administered, the container 10 will collapse due to atmospheric pressure.

no air vent is required, thereby minimizing the . . . . .
possibility of contamination. Likewise, the reinforced hanger portion 16 and particularly the card 17 which is encapsulated therein will prevent the container 10 from -~
