Abstract

A one way valve assembly flows a sterile flowable substance from a source to an outlet orifice and prevents any backflow of contaminants through the one way valve assembly when the flowable substance ceases to flow. The valve assembly includes an elastomeric membrane which aids in preventing any backflow of contaminants when dispensing of the flowable substance is stopped.

Claims

AMENDED CLAIMS received by the International Bureau on23 July 2007 (23.07.07)
1. A continuously sealing one way valve assembly and delivery system
for dispensing a flowable substance, comprising:
a source for storage of the flowable substance, the source
having an opening;
a valve assembly coupled to the opening of the source, said
valve assembly including
(i) an inner core having an inlet opening for receiving the
flowable substance into a passageway and at least one
port opening from the passageway,
(ii) a tubular flexible membrane having a first end and a
second end, the first end being thicker than the second
end, wherein the tubular flexible membrane is fitted over
an outer surface of the inner core and when the flowable
substance is placed under pressure the flowable substance
exits through the at least one port opening and expands
said membrane outwardly from said outer surface of said
inner core such that the flowable substance exits from the
first end of the tubular flexible membrane; a cover enclosing the flexible membrane and having an outlet
orifice for dispensing the flowable substance from the valve
assembly when pressure is applied to the flowable substance
and
wherein when the pressure on the flowable substance is
released, the first end of the tubular flexible membrane moves
back into tightly fitting contact with the outer surface of the
inner core before the remainder of the tubular flexible
membrane moves back into tightly fitting contact with the outer
surface of said inner core.
2. The continuously sealing one way valve assembly and delivery
system of claim 1, wherein the tubular flexible membrane has an
axially extending uninterrupted continuous band at the first end of the
tubular flexible membrane adjacent the outlet orifice in the cover and
completely encircling the core.
3. The continuously sealing one way valve assembly and delivery
system of claim 1, wherein said membrane has a radially outwardly
extending flange at the second end thereof adjacent to the passageway
of the inner core, and the cover also has a radially outwardly
extending flange pressing the flange on the membrane into fluid tight contact with a radially outwardly extending flange at the passageway
opening into the inner core.
4. The continuously sealing one way valve assembly and delivery
system of claim 3, wherein a collar and connector member on the
source secure the valve assembly to the source .
5. The continuously sealing one way valve assembly and delivery
system of claim 4 wherein the connector member is a threaded screw
which mates to the collar.
6. The continuously sealing one way valve assembly and delivery
system of in claim 5 wherein the collar and connector member on the
source effect a positive lock preventing opening of the source.
7. The continuously sealing one way valve assembly and delivery
system of claim 1, wherein the outlet orifice in the cover is arranged
so that it can dispense a selected quantity of the flowable substance.
8. The continuously sealing one way valve assembly and delivery
system of claim 1, wherein the outlet orifice in the cover is formed of
a soft material.
21
9. The continuously sealing one way valve assembly and delivery
system of claim 1, wherein the outlet orifice in the cover is formed of
a flexible material.
10. The continuously sealing one way valve assembly and delivery
system of claim 1 , wherein the cover is formed of an inner axially
extending flexible member laterally enclosed by an axially extending
rigid plastic shell.
11. The continuously sealing one way valve assembly and delivery
.system of claim 1, wherein an overcap is arranged to fit over and form
a seal with said valve assembly sufficient to prevent external
contamination from coming in contact with the valve assembly during
storage.
12. The continuously sealing one way valve assembly and delivery
system of claim 1, wherein at least two ports extend from the
passageway through the inner core and to the inner surface of the
flexible membrane.
13. The continuously sealing one way valve assembly and delivery
system of claim I7 wherein the source comprises a collapsible
22 reservoir reducible in volume in proportion as the flowable substance
is dispensed from of the collapsible reservoir.
14. The continuously sealing one way valve assembly and delivery
system of claim 13, wherein said collapsible reservoir is one of a
bellows, a tube and an internal bag.
15. The continuously sealing one way valve assembly and delivery
system of claim 1, wherein an axially extending housing laterally
encloses the source.
16. The continuously sealing one way valve assembly and delivery
system of claim 15, wherein the housing has a slot extending in the
axial direction for applying dispensing pressure to an actuator of the
collapsible reservoir.
17. The continuously sealing one way valve assembly and delivery
system of claim 1, wherein the cover has a closed outlet orifice which
opens for dispensing the flowable substance from the cover when
dispensing pressure is applied to the source.
18. The continuously sealing one way valve assembly and delivery
system, of claim 17, wherein the outlet orifice in the cover is
23 impervious to the flowable substance and does not retain the flowable
substance inwardly of the outlet orifice.
19. A one-way valve assembly and delivery system of claim 1 , wherein
the source is filled with a preservative free product.
20, A one-way valve assembly and delivery system of claim 19 wherein
said preservative-free product is selected from one of pharmaceutical
products, food stuffs, cosmetic products, and liquid vitamins.
