Claims
- 1. In a flexible tube, valve means which comprises: a tubular portion having a closed end; an elongated, generally rigid member carried on the exterior of said closed end and positioned within said flexible tube; and frangible means to permit the opening of said closed end by manual manipulation of said elongated member from outside of the flexible tube, to separate said elongated member from the tubular portion and to open said closed end, said elongated rigid member being adapted to fit in sealing relation within said tubular portion after said opening to permit resealing of the valve.
- 2. The valve means of claim 1 in which the end of said generally rigid member which is adjacent said frangible means is tapered to facilitate said fitting in sealing relation within the tubular portion.
- 3. The valve means of claim 1 in which said frangible means comprises an annular line of tearing weakness positioned at said closed end of the tubular portion.
- 4. The valve means of claim 1 in which said elongated, generally rigid member defines longitudinal vanes to provide flow channels along its length.
- 5. The valve means of claim 4 which is part of a multiple blood bag system.
- 6. The valve means of claim 5 in which said tubular member is carried within a sealed edge of a blood bag with the closed end of said tubular member pointed outwardly.
- 7. The valve means of claim 6 in which said annular line of bearing weakness includes an annular groove defined in said closed end on the side thereof opposite from the elongated, generally rigid member.
- 8. A flexible collapsible container comprising
- a sealed edge peripherally defining an interior,
- a flexible tube communicating with said interior and the atmosphere,
- a tubular valve member carried within said sealed edge of said container and extending into said flexible tube, said tubular valve member including a closed end wall blocking flow communication through said flexible tube,
- an elongated, generally rigid member carried on the exterior of said closed end wall and extending within said flexible tube outwardly from said end wall away from said container interior, and
- frangible annuular groove means on said closed end wall and defining thereon an annular zone of weakness operative for opening said closed end wall by breaking about said annular zone in response to manual manipulation of said elongated member from outside of said flexible tube to thereby open flow communication through said flexible tube.
- 9. A flexible collapsible container according to claim 8 wherein said elongated, generally rigid member defines longitudinal vanes to provide flow channels along its length.
- 10. A flexible collapsible container according to claim 9 which is part of a multiple blood bag system.
- 11. In a flexible tube, valve means which comprises: a tubular portion having a closed end; an elongated, generally rigid member carried on the exterior of said closed end and positioned within said flexible tube; frangible means to permit the opening of said closed end by the breaking of said closed end about an annular zone of weakness by manual manipulation of said elongated member from outside of the flexible tube, for opening of said valve, said elongated, generally rigid member defining longitudinal vanes to provide flow channels along its length.
